Prima Finn-Power's range of sheet metal cutting and processing solutions to be demonstrated at the forthcoming Mach 2010 exhibition will be showcased at a series of open house events. These events will take place at the company's technical centre in Italy on 26-27 March. Products on display will include the company's FB (Fastbend) manually loaded high-speed bender, the E5x servo electric turret punch press and the Zaphiro 2D laser cutter.
The Fastbend applies Prima Finn-Power's experience in servo electric technology to provide accuracy and productivity for manual bending operations. Developed as a replacement for traditional press brakes, the Fastbend allows more bends on each side of the component as part of an automated sequence, without the need for manual intervention or adjustment. It offers both rolling or circular bending modes, along with automatic tool change and barcode reader options.
Automatic setup and a self-learn capability are included alongside Fastbend's controls to ensure simple operation and minimum machine downtime. Fastbend is said to offer a low environmental impact with its efficient energy use, reduced tooling costs, minimal noise and vibration levels all contributing to the machine's low overall installation, running and maintenance costs. Similar attributes are also offered by Prima Finn-Power's latest servo electric punch press, the E5x. The E5x has been designed to provide manufacturing versatility and simple programming.
Capable of producing components from 2.5m sheets without repositioning, the machine can punch 700 holes per minute with a maximum force of 23 tonnes. The E5x also features Prima Finn-Power's Tulus Lite user interface, USB and Ethernet data transfer, and open architecture logic and motion control for precision punching performance. The Zaphiro is Prima Finn-Power's latest high-capability 2D laser machine. Incorporating linear motors, an advanced CNC controller and the company's Perfect Cut system, the Zaphiro provides cutting speeds of up to 240m/min.
The Perfect Cut system allows real-time monitoring of cutting quality and automatic correction of machine parameters. The Zaphiro stores a sample cutting piece for each material and thickness in its CNC controller. In operation, the machine detects differences to the 'perfect cut', and automatically applies adjustments to bring the quality back to the required standard. The sensitivity of the system can be adjusted by the operator - safeguarding the production of acceptable quality parts, while also eliminating expensive scrap and rework costs.
The Zaphiro's latest evolution laser head also incorporates a new F axis with higher dynamics and longer stroke, to ensure cycle-time reductions and cutting quality. Other metal cutting developments on show at the open house events include Prima Finn-Power's latest advances in fibre-laser technology. Offering high output power and efficiency, coupled with compact size and reliability, fibre lasers provide major manufacturing productivity and operating benefits, particularly on lighter gauge materials.
The use of flexible optical fibres on these next-generation machines enables the light beam to be delivered to a moveable focusing element, further improving performance and minimising maintenance downtime. Fibre-laser technology is already available as an option on the company's Syncrono 2D laser cutters and will be demonstrated at the open house events on a Platino 2D sheet metal machine.
Prima Finn-Power's combination laser cutting and punch press machinery will also be showcased at the technical centre. Examples of the company's automated work handling, storage and flexible manufacturing solutions will be on display, including the Night Train concept. This FMS system not only provides optimised 'lights-out' running capabilities, but also underlines the company's end-to-end solutions and consultancy services.

SGS Provides Storage Tank Inspection
SGS Industrial Services has introduced remote ultrasonic testing as a service, offering inspection for corrosion on difficult-to-access tank walls and roofs. Storage tank walls and roofs must be inspected regularly for corrosion. General corrosion, corrosion around liquid levels or welds and other mechanisms can attack the integrity of a tank.However, the inspection work can be difficult and expensive due to the enormous surface area, difficult access and obstacles. SGS Industrial Services can provide remote ultrasonic inspection for tank walls and roofs. With a motorised tank wall scanner with magnetic wheels, carbon steel tanks can be tested for corrosion and weld defects. This method enables remote line scans, remote spot measurements, remote time of flight diffraction (TOFD) inspection and remote visual inspection with a camera that can be steered.
SGS remote ultrasonic inspection does not require scaffolding or cranes and can be implemented on tank walls, even those with obstacles, such as wind girders and overlapping plates. This inspection technique provides detailed data on tank wall thickness with echo-to-echo measurements as required for any tank integrity assessment.
Computrace Determines Iron Content In Boiler Water
The Metrohm 797 VA Computrace is able to detect trace levels of iron in power station boiler waters. Iron in power station boiler waters can be a common problem when dark-coloured deposits are formed. Iron deposits in large amounts can inhibit the heat transfer - making the process less efficient - as well as causing corrosion problems. In the presence of dissolved oxygen any corrosion on the boiler tubing is intensified, which may necessitate the system coming offline for essential maintenance.The iron (and its deposits) can easily and reliably be measured in boiler waters using the voltammetry technique. The 797 VA Computrace from Metrohm is a modern voltammetric measuring instrument that connects to a PC directly via a USB connection. The Windows XP-based PC software controls the measurement, records the measuring data and allows full evaluation of the recorded information. The boiler water sample and auxiliary solutions were added to the reaction vessel and the iron determined using adsorptive stripping voltammetry with the Metrohm Multi Mode Electrode (MME).
A typical sample from a UK-based power station was analysed and found to contain 3.6ug l-1 of iron, demonstrating the sensitivity of voltammetry for a fraction of the purchase and the running costs of spectroscopic techniques. Calibration is performed on each and every sample using standard addition, which takes into account any background matrix effects. To enhance the accuracy and improve the sample throughput, the technique can be automated using Metrohm Dosinos (for the addition of the standard solutions) and a choice of auto samplers.
Emerson Releases DVC6200 Digital Valve Controller
Emerson Process Management has added the DVC6200 Series digital valve controller to its Fieldvue product range. The DVC6200 Series digital valve controller features linkage-less, non-contact feedback technology. The Fieldvue DVC6200 instrument was designed for applications that experience high levels of vibration, corrosion or material entrapment. The linkage-less, non-contact feedback technology improves reliability by eliminating linkage wear.The Fieldvue DVC6200 instrument has undergone electro-magnetic compatibility (EMC) testing to meet IEC standards and will ship with the CE mark. It is available with either the Hart or Foundation Fieldbus communication protocols. Orica Mining Services put the new device to work in its Kooragang Island ammonium nitrate factory in New South Wales, Australia. Orica supplies commercial explosives and blasting systems for the mining and construction industries.
The Kooragang site has standardised on Fisher valves with Fieldvue instruments. The plant also uses the Emerson 375 Field Communicator and AMS Device Manager with Valvelink Snap-On application software as part of its calibration, valve-monitoring and predictive maintenance system. Orica personnel worked with the local Emerson office to improve the performance of a Fisher valve in liquid ammonia service. The valve's high-cycle service conditions and the ammonia atmosphere in which it operates represent one of the most severe environments in any process plant.
Emerson engineers recommended the new Fieldvue DVC6200 instrument with linkage-less, non-contact feedback technology for this harsh application. Using basic hand tools, Orica's instrument technician Richard Fielding installed the new Fieldvue DVC6200 instrument on an ammonia-service valve. He said: 'This device was easy to install, program and set up. 'It has been operating trouble-free and has enabled this critical valve to provide accurate and repeatable response throughout its range of travel.
'The reliability of the Fieldvue DVC6200 instrument, plus its on-line monitoring capabilities, enables our operators to avoid manual checks and valve repairs in areas filled with ammonia vapours,' he added. Since installing the device, Orica has not experienced any production losses due to valve failures. 'This single instrument application has saved us thousands of dollars,' finished Fielding. Orica plans to order 30 Fisher valves with Fieldvue DVC6200 instruments for an upgrade at its Kooragang ammonia plant.
Objet 3D Printing Systems Use Polyjet Technology
Objet Geometries offers ultra-thin layer (0.016mm), high-resolution 3D printing systems. The company's range includes the Eden line of professional 3D printers and the Alaris range of desktop 3D printing systems, both of which are based on Objet's Polyjet technology. Top of the range is the Connex - a multi-material 3D printing system. Connex is based on Polyjet Matrix technology, which jets multiple model materials simultaneously to create composite digital materials on the fly.All of the company's systems use Objet's Fullcure materials to produce accurate, clean, smooth and detailed 3D models. Resins within the Fullcure range includes transparent, coloured, opaque, flexible and rigid properties. Fully cured models can be handled immediately after being built, whereas other RP technologies and materials require lengthy post-processing. Objet's Polyjet technology works by jetting state-of-the-art photopolymer materials in ultra-thin layers on to a build tray layer by layer until the part is complete.
The entire process is managed by the Objet studio software. Each photopolymer layer is cured by UV light immediately after it is jetted. The gel-like support material, which is specially designed to support complicated geometries is removed by hand and water jetting, making it compatible with office environments. Model production is fast due to high-speed raster build up at full width, while simultaneous building of multiple items can be accommodated.
Objet systems are said to produce a resolution of 0.016mm to ensure smooth, accurate and detailed parts and models. Objet's Polyjet Matrix technology enables simultaneous jetting of different types of model materials. Available on Objet's Connex range of 3D printing systems, Polyjet Matrix is claimed to open up several opportunities for closely emulating the look, feel and function of final products. It provides the technology foundation for 3D printing systems that can, in a single build process, print parts and assemblies made of several materials with different mechanical and physical properties.
Polyjet Matrix also allows on-demand fabrication of composite materials, called Digital Materials. This technology works by jetting two distinct Objet Fullcure photopolymer model materials in preset combinations. The dual-jet process can combine materials in several ways, enabling the simultaneous use of two different rigid materials, two flexible materials, one of each type, any combination with transparent material, or two jets of the same material.
Each material is fed into a dedicated liquid system connected to the Polyjet Matrix block, which contains eight printing heads. Two synchronised printing heads are designated for each material, including the support material, while Polyjet Matrix technology controls all of the 96 nozzles in every print head. Preset composites of model materials are jetted from designated nozzles according to location and model type, providing full control of the structure of the jetted material and its mechanical properties.
This enables each Digital Material to provide specific values for tensile strength, elongation to break, HDT and even Shore A values. The first commercial implementation of Digital Materials consisted of 21 materials. Objet then released nine additional Digital Materials, which together formed Digital Materials Pack 1. The latest Digital Materials Pack 2 includes an additional 18 materials, 12 rubber like and six rigid.
With Digital Material Pack 2, a Connex part can be printed with up to 11 materials in a single build. As well as emulating the mechanical properties of the target design, Polyjet Matrix allows the combination of black and white rigid materials, creating a range of greyscales suitable for consumer electronics and other applications. It also reduces the risk of error when creating complex moulds for double injection by enabling the majority of testing to be performed on early stage prototypes instead of requiring silicon moulds. Companies interested in 3D printing can contact Objet Printing Solutions for a no-obligation demonstration, or request a free sample 3D model from CAD data.
Controllers Enable High-Temperature Processing
National Instruments has released two Compact RIO programmable automation controllers (PACs). These are said to offer engineers and machine builders an ideal solution for high-performance measurement and control applications operating at extended temperatures. The NI cRIO-9023 and NI cRIO-9025 real-time controllers are also available with conformal coating for additional protection of components and circuitry within harsh conditions.The Compact RIO controllers provide even more processing for advanced measurement and control applications ranging in temperatures between -40 and 70C. The NI cRIO-9023 controller has a 533MHz Power PC processor and the NI cRIO-9025 controller has an 800MHz Power PC processor, as well as dual Ethernet ports for network programming, communication and expansion I/O.
Both controllers work with the existing Compact RIO reconfigurable chassis, which include field-programmable gate arrays (FPGAs) that are programmed using the NI Labview 2009 graphical system design platform.
Using Labview and Compact RIO, engineers can quickly implement custom analogue and digital control loops, along with high-speed signal-processing algorithms to meet their advanced measurement application needs. In addition to an extended operating temperature, the Compact RIO controllers are available with conformal coating.
This coating is a specially formulated thin film material applied directly to circuit boards or circuit card assemblies and provides an impermeable seal to protect circuitry from humidity, moisture, mould, mildew, fungus, dust and corrosion caused by exposure to extreme environments. Application areas in which conformal coating can provide protection include marine, railway, automotive, factory monitoring, fuel-cell testing and oil and gas refining.
Lubriserv Offers Vanishing Forming Lubricant
The Evolution range of vanishing fluids can be used in fin forming or drawing and magnetic sheet pressing as it removes the need for cleaning prior to the next operation of brazing or welding. The vanishing fluid dissociates without smokes, flames and residue. During the brazing phase, it does not form aldehydes. Other features include increased die and punch life, seizing up elimination, less down time, clean fin or worked sheets, eliminating washing operations.
Vanishing lubricants disappear after the forming/pressing operation. These compounds leave a light coating of lubricant on the part during pressing and then evaporate shortly afterwards. In most cases, the vanishing lubricants can completely eliminate the need for cleaning operations. Lubriserv claims its vanishing oils do not turn tacky, have mild or no odour and are designed to always remain as fluid.
Vanishing lubricants can be used both on ferrous and nonferrous metals. Low viscosity vanishing lubricants are suitable for light-duty stamping, pressing and blanking on ferrous and nonferrous metals. Products are non staining and formulated to leave minimal film on components so that any post assembly operations such as welding or brazing can be carried out without inter-operational washing or excessive smoke and fumes.
Latest synthetic vanishing technology is designed for thermal degreasing at low temperature leaving no residue on components after processing. Products are also completely odourless for operator acceptance.

AMP Launches Multi-Format Video Encoder
Advanced Micro Peripherals (AMP) has unveiled a multi-format video encoder that combines graphics overlay, motion detection and enhanced watermark authentication on a PC/104-Plus module. The MPEG4000WA captures and compresses up to four concurrent live analogue video inputs to full D1 resolution using either MPEG-4, MPEG-2 or M-JPEG encoding standards.The board can also encode audio for each video channel. It can decompress and play back recordings from storage to display and offers an additional incoming live video path for a simultaneous preview on the host screen. Digital watermark authentication technology assures users that the recorded data is protected from unauthorised tampering, modification or editing. It uses a patented digital watermarking algorithm, which is classed as sensitive, making any attempted interference with the data immediately evident during playback.
The algorithm is sensitive to most image manipulation operations, including scaling, cropping, frame removal and insertion and macroblock swapping. The detection of spatial and temporal tampering is also possible. For digital-video-recorder (DVR) and video-streaming applications, the MPEG4000WA enables full bit-mapped graphics overlay with several levels of alpha blending to be combined with the live video for both preview and compression.
The board also supports motion detection (based on a defined region of interest) along with a 'babysitting' mode, which can be used to control the recording process based on detected activity. With the supplied SDK, user-defined data such as camera identification, date, time and location can be added to the video image. The MPEG4000WA is supported by a suite of drivers for embedded PC-based Windows XP/XP Embedded and Linux systems.
The standard video-recording SDK and sample applications are supplied free with the board. AMP also offers a video-streaming SDK, enabling compressed video to be streamed in real time over an IP network. The MPEG4000WA is available as both commercial and extended-temperature-range (-40C to +85C) variants and may also be supplied with a conformal coating for defence and industrial applications.
Search Tool For Power-Supply Designers Launched
Power Integrations has launched the EuP Standards Finder, an online tool for power-supply designers. Providing access to the specific requirements of the European Commission's EuP Ecodesign Directive, this tool eliminates the need for designers to search through volumes of data to figure out what is relevant to them, according to the company.Hosted on Power Integrations' website, the EuP Standards Finder allows users to select an application from an A-to-Z listing and then immediately view the tier-one and tier-two limits for standby, active-mode and no-load power consumption. Links to relevant Power Integrations reference designs are also displayed in the search results. Commentary from energy-efficiency standards specialist Mr Green provides an additional insight into how the Ecodesign Directive applies to the specified product.
AVX Expands TPM Range Of Tantalum Capacitors
AVX has expanded its TPM series of multi-anode mirror-design tantalum capacitors, offering improved robustness and featuring very low ESR. The D-sized TPM 47uF/25V part offers an ESR of 55mohm. In comparison, a single-anode part in the same package has an ESR of 100mohm. For the E-case device (which has the same footprint but a bigger case size), the minimum ESR is 80mohm.By reducing ESR by 30 per cent, the new capacitors offer an improvement in filtering capabilities, even to the extent that one part can sometimes replace two standard single-anode devices. Also new in the TPM range, the company has released mirror-design multi-anode parts rated at 35V. The TPM D 22uF/35V is suitable for use in circuits with high currents and voltage spikes where the profiles are limited to 3mm.
It is particularly suitable for automotive battery applications running on 12/14V with very low impedance, where it also offers greater robustness and a lower ESR than single-anode capacitors. Since D- and E-case sizes use an identical footprint, the pad design does not need to be changed if the D-case part can be used to replace the larger capacitor. For higher operating voltages, the TPM D 10uF/50V with an ESR of 140mohm is also available. All parts meet the requirements of AEC-Q200, which is said to be a key requirement for automotive designs in Europe.
RF Connector Uses Deep-Drawn Manufacturing Process
Quadrant has teamed up with IMS Connector Systems to develop a radio-frequency (RF) connector that uses a deep-drawn manufacturing process to conform to strict technical and price specifications. Sold under the IMS Part No 3951.11.1412.231, the new connector is a 75ohm SMZ (BT43) bulkhead cable-mount connector designed for TZC75024 coaxial cable.
The connector was developed to meet the specific demands of a European telecommunications company for use on digital distribution frames. The new design uses the deep-drawn process, a method in which a sheet-metal blank is radially drawn into a forming die by the mechanical action of a punch to reduce the process time and component count. Rather than having three parts - the body, the spigot and the ferrule - the deep-drawn process reduces this to just two.
The result is a connector that has been designed to comply with the IEC 169-28 (Type SMB 75), that has been tested to IEC 60068-2 environmental influences and that meets the tight cost target and demanding technical specification set by the customer. It is capable of 500 mating cycles and is suitable for use in analogue or digital telecommunications systems.

Kaman Selects Fibersim Engineering Software
Vistagy has entered an agreement to license Fibersim composites-engineering software to Kaman Helicopters. The software will be used to streamline the design-to-manufacturing process for large composite helicopter blades by providing early visibility into production challenges and facilitating smooth communication of composite manufacturing data to the shop floor.Based upon an extensive evaluation, Kaman estimates that Fibersim will enable the firm to reduce ply development time from 180 to 40 hours, a saving of 78 per cent, and average part layup time from 32 to 20 hours, a saving of 38 per cent. Kaman Helicopters will leverage Vistagy's composites expertise by employing its professional-services organisation to help develop and implement best practices for standardising composites-development processes.
Kaman Helicopters is using Fibersim within its Siemens NX computer-aided-design (CAD) system. Fibersim is completely integrated into major 3D commercial CAD systems to provide powerful functionality specifically for developing products made of advanced composite materials.
Kaman Helicopters selected Fibersim because defining ply flat patterns for each ply in a composite design was taking too much time. By implementing Fibersim, the firm expects to significantly reduce the hours required for ply development and layup, streamline its manufacturing process and eventually eliminate the use of Mylar patterns. Kaman Helicopters is using the software to define flat patterns as well as generate data to drive its laser-projection system.

Preparing Mixes For Determining Octane And Cetane
PC-controlled automatic dosing devices from Metrohm can automate preparation of surrogate mixtures for determining octane and cetane numbers. Commercially available fuels are complex mixtures of hundreds of different hydrocarbons. For the calibration of the test engines or advanced experimental and computational research they are modelled by means of multi-component surrogate mixtures that adequately represent the desired physical and chemical characteristics.By definition, every octane and cetane number corresponds to a specific mixing ratio of primary reference fuels (PRFs). Based on this information, the tiamo-controlled automatic dosing device prepares the surrogate mixtures. The setup drastically minimises time-consuming and error-prone manual-preparation steps and contact with hazardous solvents. Additionally, precise and accurate results are displayed on customisable reports that fully comply with all current GLP and GMP requirements. The octane rating of gasoline is a parameter that indicates how much a fuel can be compressed before it spontaneously ignites.
This spontaneous ignition is also known as engine knocking and adversely affects engine performance. The higher the octane rating of gasoline, the higher the resistance to knocking. By definition, the octane rating of isooctane, a highly branched alkane that burns smoothly, is set to 100. The rating of n-heptane, an unbranched alkane with a tendency for premature ignition, is set to zero. An octane rating of 85 means the fuel has the same knocking properties as a mixture of 85 per cent isooctane and 15 per cent n-heptane. There are different octane ratings such as the research octane number (RON) or the motor octane number (MON).
Both are determined using the fuel on a test engine (such as the CFR ASTM Test Engine) and comparing the obtained results with those for mixtures of isooctane and n-heptane. The different ratings result in different working conditions of the test engine. As the preparation of the solvent mixtures significantly affects the accuracy of the determination of the octane rating, strictly accurate solvent mixtures are of paramount importance. PC-controlled automatic dosing devices allow a straightforward, reproducible and accurate preparation of solvent mixtures. Additionally, the manual handling with hazardous solvents is minimised, which translates into increased operator safety.
The instruments required for this are: the 846 Dosing Interface, Dosino 800, dosing unit and 840 Touch Control Surrogate mixtures. The wide range of hydrocarbon species in commercial gasoline complicates the understanding of fundamental physical and chemical processes in the test engine. A substantial number of surrogate mixtures, mainly consisting of the primary reference fuels (PRFs) n-heptane, iso-octane and toluene, have been developed to mimic concrete fuel properties. The calibration of internal combustion engines used for measuring the motor octane numbers (MONs) of gasoline, for example, requires the accurate preparation of a high number of surrogate mixtures with known MON.
An automated dosing system that is fully controlled by tiamo replaces the tedious, time-consuming and error-prone manual preparation of surrogate mixtures. Whereas for gasoline the desirable property is the ability to resist ignition when injected into the engine, the desired property of diesel fuel is to auto-ignite. The relevant parameter is the cetane number. A compound that has a high octane number tends to have a low cetane number. Binary surrogate mixtures, consisting of the PRFs cetane and a-methylnaphthalene, are needed to adequately describe the chemical complexity of conventional diesel fuels.
Advantages include: upgradable custom-designed setup - surrogate mixtures of numerous primary reference fuels can be prepared; preparation of variable sample volumes between 0.1 and one litre; fully automated dosing minimises manual handling with hazardous solvents; accurate and precise dosing provides highly reproducible surrogate mixtures; detailed and customisable reports are in accordance with GLP and GMP; and the parallel dosing of the primary reference fuels saves time - the preparation of a 200ml surrogate mixture takes less than 5min.
Hach Lange Instruments Enable De-Sludging Trial
Severn Trent Water (STW) has initiated a de-sludging trial to reduce costs and energy consumption by producing thicker sludge in the Primary Settlement Tank (PST). Advanced monitoring instrumentation from Hach Lange played a key role in the trial. STW's Mark Bryan summarised the objective of the trial: 'We believed that if we could monitor and control the settlement process through a real-time control mechanism, we would be able to produce thicker sludge, reduce operational intervention and save the energy and costs involved with further sludge thickening prior to the sludge-digestion process.The trial took place at STW's Stoke Bardolph Sewage Treatment Works. Monitoring and control instrumentation was provided by Hach Lange and a hydraulically operated ram pump with an adaptive control system was provided by EMS Industries. A Sonatax SC probe was deployed for the measurement of sludge blanket level and a Solitax SC probe provided suspended solids and turbidity values. All data was handled by an SC 1000 plug-and-play controller, which interfaced with the EMS adaptive-control system to manage the pump operation.
Hach Lange's Jon Shepherd explained the role of instrumentation in achieving the objectives: 'It was the aim of this trial to establish if thicker sludge could be created in the PST and pumped. 'The benefit of pumping thicker sludge is that more solid material can be transported per litre of water pumped, which provides energy savings and improved process efficiency. He added: 'Our instrumentation reliably monitored the sludge levels under a number of different de-sludging scenarios, including pumping with various sludge densities and using different PST settlement times.
Paul Hawthorne, technical director at EMS said: 'The Hach Lange instrumentation enabled us to refine our adaptive pumping system, allowing the full capability of our pump to reliably pump thick sludge to be achieved. The trial demonstrated that sludge in excess of 5.5 per cent solids has been automatically controlled and regularly drawn from the PST. Sludge blanket-level stability has been maintained by the EMS pump's adaptive-control system, which varied the speed of the pump stroking action to suit changing sludge conditions.
Hach Lange's SC1000 control unit enabled the pump to be run only when a minimum sludge blanket level had been achieved and for pumping to cease when sludge density reached the preset low level (5.5 per cent for the trial). The EMS system is now pumping sludge with solids of over twice the concentration of the traditional system (progressing cavity pump).
Mark Bryan said: 'The trial has shown that the original objectives have been met; the new pump runs for approximately 3hrs each day, as opposed to 8-16hrs with the previous system, resulting in considerable energy savings and increased process efficiency. 'This project has proved that the EMS ram pump can operate comfortably at 5.5 per cent solids and that the accuracy and reliability of the Hach Lange instrumentation has been key to the success of the system.

Application Note Explores NIR Chemical Imaging
Chemical imaging specialists at Malvern Instruments have published an application note. The note demonstrates that, by reverse engineering pharmaceutical tablets using data from the Synirgi near-infrared chemical-imaging (NIR-CI) system, they could determine extensive and detailed information about the formulations and processing techniques used to create each dosage.This is said to have valuable applications in troubleshooting product failures. The application note, entitled 'NIR chemical imaging for tablet deconstruction: A case study for solid dosage forms', can be downloaded from the Malvern knowledge database on the website. While high-performance liquid chromatography (HPLC) can provide basic information about a product makeup, the application of NIR-CI adds novel information relating to its manufacture.
Using Malvern Isys chemical-imaging analysis software to evaluate the size, shape and proximity of chemical components, the Synirgi global imaging approach provides a visual representation of a product composition and engineered structure. Synirgi delivers robust automated sampling capabilities that deliver rapid data acquisition, as well as advanced data analysis via an easy-to-use interface. The NIR-CI technique demonstrated in the Malvern application note takes advantage of Synirgi hardware and Isys software advanced features.
This type of reverse engineering has demonstrated the ability to help understand product failures and can primarily be used for troubleshooting. The wealth of chemical and physical information in a chemical image provides a fingerprint of the tablet production properties and, ultimately, its performance. It is suitable for pharmaceutical dosage analysis and enables refined quality control.
Dynsim Gives Medium-Fidelity Simulation Solution
Invensys Operations Management has announced the availability of its Simsci-Esscor medium-fidelity simulation solution, Dynsim Checkout. Available as part of the Dynsim 4.5 software release, the solution provides the industry with a way to quickly identify, validate and resolve control- and safety-application design errors throughout the project life cycle, while addressing plant-operator process-familiarisation needs and clearing obstacles such as late-arriving design information.Medium-fidelity simulation provides a library of unit-operation models (valves, pumps, conveyers, reactors) similar to high-fidelity models, but requires far fewer engineering hours and less specialised expertise to configure and tune. The models can be auto-generated using plant life-cycle management software that features intelligent piping and instrumentation diagrams (PandID), shortening the time it takes to construct the model.
The Simsci-Esscor medium-fidelity simulation solution also requires less design data to complete the model, with PandID and process flow diagrams being the key required information. By providing this simulation facility the early stages of the project, potential control and safety-application design errors, omissions and changes can be captured before construction, resulting in higher quality for the automation system, as well as significantly reduced client risk at the plant startup and commissioning phases.
Medium-fidelity models, while less complicated than high-fidelity, are also suitable for operator familiarisation training, allowing operators to learn procedures 'live' on the new control platform and to attain a level of knowledge that was previously impossible at such an early stage in the project. These models can be efficiently rebuilt many times throughout the life of the project and can therefore remain current with the latest control and safety designs.
Cogent Urges Employers To Shape Vocational Future

Weighing Technology Reduces Product Giveaway
Weighing technology and software from Avery Weightronix has reduced product giveaway and improved the yield from a batch of chemicals for Schlotter by five per cent. Schlotter blends chemicals for a variety of industries, including automative, microelectronics, metal finishing and medical devices. The cost of blended chemicals varies but can be up to EUR50/kg, so process efficiency was a key driver in the company's lean manufacturing programme.
Schlotter would normally fill 25kg to 1,000kg containers but would also offer product in 1kg to 10kg bottles of the blended chemical, depending upon customer requirements. Previously the operator would place the drum or other container on to a floor scale and then fill it manually to the required level. In order never to short ship, the operator would overfill these containers so, for example, a 25kg drum could receive 1kg extra and sometimes as much as 2kg.
Giveaway was even more extreme on the smaller 4l bottles - often up to 10 per cent extra. Another problem was that if there was any spillage or product left in the filling tank, then the company has to pay for its proper disposal as a hazardous waste, in line with its IPC licence. Avery Weightronix installed and programmed its Evolution E1110 indicator to control the pump and filling head from the filling tanks in response to the weight readings from the existing floor scales.

Orbit3 System Networks All Industrial Sensor Types
Solartron Metrology's high-speed Orbit3 networking system is a fast and simple way to network industrial sensors of all types, including dimensional and position-measuring transducers. It builds on the Orbit2 system, offering substantial improvements and enhancements. Among the new enhancements are greater accuracy, which has been halved to 0.05 per cent of reading, and improved diagnostics, with local LED diagnosis displayed for each unit.The sensors are now hot-swappable - an advantage where a large number of sensors are employed, such as in the manufacture of automotive windscreens. Up to 200 probes can be connected in a single network. Orbit3 is a means of building large, flexible sensors and gauging systems with a single common interface, regardless of sensor technology. Its high data-transfer rates provide dynamic and synchronisation capabilities for the measurement of moving parts.
In addition to Solartron digital transducers, the network allows a range of third-party sensors to be connected, including pressure, temperature and force transducers. At the heart of the network is Solartron's digital probe technology coupled with a robust RS485 multi-drop communications link. A system of nine-pin lockable connectors called T-Cons is used to channel the output of each input/output device on the network to the receiver electronics for analysis and display.
Each module has a unique identifier that simplifies data acquisition, especially in large multichannel networks. The new T-Cons are more robust, with a double latching mechanism and reduced weight, making them suitable for high vibration applications. They can be used individually, daisy-chained using computer cable or banked together in blocks to form a multichannel nest. DIN rail mounting is an option, as is IP65 environmental protection. Connection to PCs and PLCs is possible via an RS232 interface, with Ethernet communication models available shortly. Orbit3 is suitable for use in a range of industries, including automotive, aerospace and consumer electronics as well as test and instrument laboratories.
Renishaw To Show Resolute Absolute Encoder At MTEC
Renishaw will display its latest range of optical incremental encoders at MTEC, which will take place at the NEC, Birmingham from 27-28 April. Demonstrations will include a 1nm resolution version of Renishaw's Tonic incremental encoder, a magnetic chip encoder and an absolute optical encoder capable of 10 atoms resolution at 220mph and suitable for rotary and linear applications. Renishaw's Resolute absolute optical encoder system gives a 1nm resolution at 100 metres per second for both linear encoder and angle-encoder applications, yet still offers excellent dirt immunity.Absolute position is acquired immediately at system switch-on, so the exact orientation of axis and motor commutation angle are known without the need for a reference (datum) return. Large set-up tolerances also enable easy installation and high reliability, while low jitter and SDE (sub-divisional error) meet the demands of high-precision stages. The Tonic range of incremental optical linear and rotary encoders now offers 1 and 2nm resolutions, a dual-output encoder interface and is also available with Renishaw's Dual Signal Interface (DSI).
The higher-resolution options comprise a standard Tonic readhead and new interfaces that apply high interpolation rates to achieve fine resolution and low jitter levels of just 0.51nm RMS. For applications requiring one or more operations to be synchronised with a motion axis, the new dual-output interface simultaneously provides analogue and digital signals. For high-accuracy angle encoding, the new Tonic DSI allows two readheads to be used to improve the accuracy and repeatability of a motion system by eliminating eccentricity, bearing wander and all 'odd' error harmonics.
Renishaw's AM4096 magnetic encoder IC offers 12-bit resolution (4096 steps per turn) and is capable of high-speed operation to 30,000rpm. It provides UVW outputs with 16 poles (eight-pole pairs), incremental, absolute, linear (potentiometer), tacho generator and sinusoidal outputs. Typical applications include commutation and high-speed motor control, position and velocity control, potentiometer replacement and optical-encoder replacement.

Tacom Selects Sturman Digital Injector For Engines
Tank-Automotive and Armaments Command (Tacom) has contracted Sturman Industries to execute the objective of SBIR A09-199 'Ultra High Pressure Jet Propellant-8 (JP-8) Fuel Injection'. This objective is: 'To examine, develop and demonstrate a hydraulically intensified, ultra-high pressure fuel-injection system that will be durable, increase power density relative to volume and or weight, increase fuel economy and reduce specific heat rejection of high-output military diesel engines that are required to operate on heavy-hydrocarbon fuels, including Jet-A1, Jet-A, JP-5, JP-8 and DF-2.
Eddie Sturman, co-founder and chief technology officer of Sturman Industries, is well versed on the current and future fuel-system requirements of the US military. 'Fuel-injection technology from Sturman Industries is currently utilised on MRAP (Mine Resistant Ambush Protected) vehicles in the battlefield. 'Tardec has provided us the opportunity to build upon the success of the hydraulic intensification platform to further demonstrate the ability of the Sturman Digital Injector with regards to ultra-high pressure, rate-shaping, multiple events and multi-fuel capability,' he said.
The Sturman hydraulically intensified fuel injector with intelligent electronic controls and ultra-high pressure capabilities has the potential to improve the performance of engines from military and commercial diesel engines to off-road trucks, passenger cars or ships. In general, higher injection pressures allow for better fuel atomisation and more complete combustion of the fuel, which increases the engine efficiency and reduces the unburned hydrocarbons in the engine exhaust.
At higher injection pressures, it is also possible to inject larger fuel quantities at the same time through the same nozzle holes. This produces more torque and power from the engine while maintaining good atomisation necessary for efficient combustion. Sturman Industries is targeting injection pressures as high as 3000 bar with the latest injector models. The aim of generating injection pressure is to intensify the fuel locally at the injector.
A hydraulically intensified fuel injector has several advantages over a non-intensified fuel injector, especially regarding the capability of running with different fuel types at high pressures. The first benefit is that the fuel is pressurised locally inside the injector rather than in an external pump.
Therefore, the system does not require a pump capable of working with multiple fuel types at ultra-high pressures. This eliminates a significant challenge because the lower lubricity of fuels such as JP-8 used by the military creates wear and durability issues for many of the pump components at these high pressures. In the Sturman injector, only a limited number of sliding parts come into contact with high-pressure fuel, reducing the wear issues caused by low lubricity.

Barden Cuts Bearing Costs On Hippag Air Generator
Barden has helped Ultra Electronics Precision Air Systems to reduce bearing costs and assembly times on its high-pressure pure air generator by 40-50 per cent. Ultra produces a range of mini-compressors known as Hippag (High Pressure Pure Air Generators). These are compact, lightweight, electrically powered air compressors that are carried on-board various military platforms. The Hippag airborne compressor provides a continuous source of high-pressure pure air to cool the infrared seekers of an aircraft's defensive missiles, keeping them ready for action.Hippag also provides a controllable energy source for the pneumatic ejection of aircraft munitions, while meeting the emerging requirement for launching increased quantities of smaller, smart munitions. More than 5,600 Hippags have been delivered for defence applications around the world. Hippag has been developed for the F-35 JSF aircraft and is being supplied for Boeing's Small Diameter Bomb programme, the Eurofighter Typhoon, the US Marine Corps AV-8B Harrier, AH-1W Supercobra, F/A-18 C/D Hornet and the US Navy F/A-18 E/F Super Hornet aircraft.
At the heart of the Hippag system is a bearing assembly based on a swash plate configuration. Supplied by Barden, this super-precision bearing is a customer-designed assembly that comprises a pair of bearings mounted on a cranked shaft with a 15-degree offset between axes. The bearing's main function is to transfer rotary motion into linear motion, enabling the axial motion of the Hippag compressor pistons. The bearing assembly will typically comprise a pair of solid, pre-loaded angular-contact bearings on the swash axis and a second pair of angular-contact bearings for the shaft axis, which are spring preloaded and share a double row inner ring.
The bearings are made from carbon chrome and use standard steel balls, as the Hippag application speeds are relatively low (less than 700rpm). These two bearing sub-assemblies are then mounted onto the offset shaft. Ultra subsequently receives this completed sub-assembly from Barden, which it simply drops into its Hippag housing to mate with the brushless DC motor, which sits on one side of the bearings, with the compressor on the other side. Martin Carpenter, engineering director at Ultra, said Barden's original design was selected because it utilised lower-cost manufacturing methods that used existing tooling and (at the time) a cellular-manufacturing approach that also contributed to a lower-cost bearing solution.
The new bearing assembly integrates directly with the Hippag unit and is smaller and lighter than the original. The original flange-mounted assembly has been replaced with a threaded outside diameter that enables through-grinding. 'The latest design incorporates precision-milled "pots" in the outer ring for the piston rod ends, which reduces the component count. 'Over the years, we've made lots of design iterations, including a low-duty unit in SAE52100 and a special high-duty unit that uses our "Cronidur 30" corrosion-resistant steel with its increased fatigue strength,' said Gary Hughes, application engineering manager for aerospace at Barden.
According to Hughes, there were several engineering challenges to be overcome. For Barden, Hippag is a low-speed high-load application with a short life of less than 500 hours and so the design had to reflect this. Hughes added: 'Through a 360-degree revolution of the Hippag, there's a constantly varying load cycle on the bearings and so we had to develop new methods of modelling this. 'This led to a bearing devolved from the original Ultra design to two bearing pairs and a cranked shaft. 'Investment in new machinery at Barden also enabled us to reintegrate the bearings into the Hippag shaft. 'We were able to eliminate the use of external clamping by incorporating threaded outside diameters on the bearings,' finished Hughes.
Rockwell Unveils Ethernet/IP Indexing Servo Drive
The new Allen-Bradley Kinetix 300 Ethernet/IP indexing servo drive from Rockwell Automation enables machine builders and end users to standardise on a single communication network. This is intended to facilitate commissioning, configuration and start-up. With the new drive, the entire control solution - including the human-machine interface, programmable automation controllers, input/output and motion - can be connected over a standard Ethernet/IP network.According to James Grosskreuz, product manager at Rockwell Automation, the Kinetix 300 servo drive can eliminate the need for a dedicated motion network while maintaining high-speed connectivity with excellent reliability. With the ability to support up to five indexing types and 32 indices, the Kinetix 300 servo drive is suitable for indexing tables, intermittent horizontal and vertical form/fill/seal machines and simple sleevers, case packers and erectors.
By combining the Kinetix 300 servo drive with the Allen-Bradley MP-Series or Allen-Bradley TL-Series motors, along with the Allen-Bradley Compactlogix L23 or Compactlogix L32 controller, the company now delivers an option for machines that demand the power of the Rockwell Automation Integrated Architecture system in a cost-effective package for low-axis-count motion solutions. The drive can work with an Allen-Bradley Micrologix processor to help deliver a cost-effective component machine-level solution. The Kinetix 300 drive features seamless integration with Rockwell Software's RSLogix 5000 through a Kinetix 300 add-on profile.
It also has drive-based web configuration tools. As a result, machine builders do not need to learn, load or maintain dedicated motion software. To help protect personnel and increase productivity, the Kinetix 300 servo drive also comes equipped with safe torque-off functionality. With the safe-off capability, tasks such as machine setup, cleaning, the removal of jams and other typical maintenance work that previously required power-down conditions can now be accomplished without removing power from the entire machine.
Instead, drive output can be safely disabled, enabling faster machine restart and shorter machine downtime, according to Rockwell. Components such as input contactors are not required, simplifying machine design and helping reduce both panel space requirements and overall system costs. The Kinetix 300 servo drive features a compact size and has the available voltage and power ranges to meet a range of global machine requirements, including applications in the packaging, alternative energy and manufacturing and assembly industries.
