Four UK polymer companies will hold a new one-day conference entitled 'Improvement in Production Efficiency', which is aimed at increasing performance and efficiency in the processing of plastics. GandA Moulding Technology, a plastics consultancy and training provider, will host the event at its Peterborough facility on 13 April 2010 and will repeat it the following day. This is in conjunction with machinery supplier Premier Moulding Machinery (PMM), polymer distributor Velox (UK) and Triton Technology.
The conference will consist of a series of papers and practical demonstrations intended to be of interest to polymer processors that are seeking to boost their own production efficiency. At the event, GandA will present its Pro-Op process-optimisation software, which allows users to optimise their processing in a step-wise and logical approach, with an emphasis on process consistency and component quality and, as a consequence, a fall in energy costs through the reduction of scrap and downtime.
PMM will present the Venus series of all-electric injection-moulding machines from Zhafir Plastics Machinery. The Venus series can result in 20 to 70 per cent less energy consumption compared with hydraulic machines and a 10 per cent lower consumption than other general servo machines. PMM will hold a live demonstration of the Asaclean purging compound and mould cleaner for extrusion and injection-moulding equipment. Triton Technology will show its Identipol QA, which uses Dynamic Mechanical Analysis (DMA) and Differential Scanning Calorimetry (DSC) to provide simple and cost-effective quality-assurance testing of mouldable thermoplastics.
It can help prevent the loss of time and money on sub-standard materials. Beyond practical demonstrations of the equipment and systems mentioned above, there will be talks on the advantages of injection-moulding technology training and the savings to be made by investing in power-efficient equipment.
ISD860 Drives Gives High Servo Performance Control
Based on Technosoft Motionchip DSP technology, ISD860 is a flexible intelligent drive. It has been developed for motion applications that require cost-optimised design, embedded intelligence, networking possibilities and high servo performance control. It is able to drive 12A continuous and 31A peak currents at a supply voltage ranging from 12 to 72V DC, with a PWM of 20 kHz frequency. Embedding motion controller, drive and PLC functionality in one 136 x 84 x 26mm unit, ISD860 controls brushless, DC or linear motors up to 860W continuous/2.2kW peak voltage.Due to its advanced motion-control algorithms, a precise control of position, speed or torque over a range of dynamic conditions can be achieved. ISD860 works in single-axis, multi-axis or standalone configurations. The drive setup, tuning and motion programming are made simple with Easymotion Studio and Technosoft Motion Language (TML), according to the company. With ISD860, motion programming can be done from a CAN master, via PC/PLC, using the appropriate motion library, or directly at drive level through its built-in motion controller.
The embedded Technosoft Motion Language includes a high-level command protocol, which can be used by the host through the onboard RS232/CAN serial interfaces. A CANopen version of the ISD860 drive, supporting DS-301 and DSP-402 profiles, is also available. In standalone operation, ISD860 can be managed with programmable I/Os or analogue inputs. Using the TML language, multiple operations can be performed with ISD860: setting of various motion modes (profiles, PVT, PT, electronic gearing or camming, etc), change of motion modes and/or parameters, execution of homing sequences or program flow control.
At the same time, IDS860 can handle digital I/O and analogue input signals, execute arithmetic and logic operations, and transfer data between axes. The drive is able to control other axes via motion commands. ISD860 can send commands to a group of axes, or synchronise all the axes from a network. Flexibility and easy implementation make ISD860 suitable for higher-power motion axis-control using modern distributed intelligence architecture. The drive is suitable for cost-sensitive applications, from medical to factory automation, requiring high servo performance and enhanced compactness.

JVL Servo Motors Support Modbus RTU Protocol
The latest firmware for JVL Industri Elekronik's integrated servo motors - MAC400 and MAC800 - now supports the Modbus RTU protocol. The implementation supports the Read Holding Registers and Write Multiple Registers commands, which will give R/W access to all motor registers at speeds up to 1Mb/sec, though typically the PC standard rates of 9,600;115,200 and 230,400 bit/sec would be used.The implementation uses the original V1.1 version of the Modbus protocol for maximum compatibility. For systems requiring a two-wire RS-485, the MAC00-P4 interface module is used. For four-wire RS-422, the MAC00-FSx modules or one of the MAC00-Bx modules are used.
Sysgo Software Offers Multi-Core Implementation
Sysgo has released version 3.1 of its flagship product, PikeOS, which is said to offer the first multi-core implementation on the market that is part of a DO-178B-certified code basis. The release maintains what is said to be one of the main benefits of PikeOS technology: the same core components are used whatever the market segment. Application specifics are isolated within 'personalities', a concept that allows all PikeOS customers to benefit from the same software layers underneath: PikeOS System Software and PikeOS micro-kernel.Multi-core support through a flexible approach is made available to the user, who can select an execution model ranging from a pure AMP (Asymmetric Multi Processing) to full SMP (Symmetric Multi Processing). The SSV (safe and secure virtualisation) design developed by Sysgo makes it particularly suitable for multi-core architectures. The resource and time partitioning model makes the development of concurrent applications on multi-core platforms easier for the user: only core assignment needs new action from the user and the rest of the partitioning remains the same as before.
Multi-core related code is integrated within the certified code basis and is hardware agnostic, in line with the original PikeOS principle. Supported processors are the x86, PowerPC, MIPS, ARM and SPARC. The supported personalities are the PikeOS Native, ARINC-653, Linux, Posix and Certified POSIX. The multi-core capability is fully implemented on Intel families. Available hosts are Windows and Linux.

Holotouch Launches Touchless Interface
HoloTSFS408 is a touchless human-machine interface that is operated by inserting a finger into the holographic image of OPEN floating freely in its central cavity. It is powered by a switch-mode, regulated 5V DC output power supply with input voltage that can range from 100V AC to 250V AC at 50, 60 or 400Hz, and has a maximum output current of 1A DC. In demonstration units, there is an auxiliary, unregulated output of 10V DC that is used to power the green LED array at the bottom of the demonstration stand.Internal components of HoloTSFS408 consist of a hologram, an LED to reproduce its holographic image and an infrared sensor, the 'sweet spot' of which coincides with the centre of the plane of its reproduced holographic image. The hologram is laminated between two 2.5 x 2.5in plates of 1/8in acrylic. HoloTSF408's reproducing light source is a super-white LED with a luminous intensity of 20,000mCd (If=20mA), a viewing angle of 20 and a forward voltage of 3.2V. HoloTSF408's sensor is a distance-measuring sensor unit composed of an integrated combination of photo diode, infrared emitting diode and signal-processing circuit.
An object must remain in the infrared sensor's sweet spot (50mm from sensor) for at least 160msec in order to generate an activation command. There is an 800msec inter-activation interval programmed into HoloTSF408's infrared sensor. This sensor consumes 5mA. HoloTSF408 is a double-insulated product and, as such, does not require a ground-wire connection.

Linear Launches Current Monitor For 4-80V Systems
Linear Technology has introduced the LT2940, a power and current monitor for 4 to 80V systems. The LT2940 provides the necessary circuits to accurately measure, monitor and control power in situations where both the current and voltage may vary due to supply-voltage uncertainty, component parametric changes, transient conditions or time-varying signals.
It uses a true four-quadrant analogue multiplier that results in five per cent power-measurement accuracy and three per cent current-measurement accuracy, ensuring that boards and systems achieve optimum power efficiency and reliability. The LT2940 is suitable for use in line cards and servers, power-sense circuit breakers, power-control loops and a variety of metering applications. It measures a high-side current and differential voltage, and calculates the instantaneous power at a bandwidth exceeding 500kHz.
Bidirectional high-side currents and bipolar voltage differences are correctly handled by a four-quadrant multiplier and push-pull output stage, which allow the device to indicate forward and reverse power flow. After current and voltage measurements are taken, current and power levels can be scaled, filtered and monitored separately via their respective proportional-to-current and proportional-to-power current outputs.
Meanwhile, an integrated comparator with complementary open-collector outputs can be used to create PWM control loops, or provide simple logic of, for example, an over-power pin, an LED indicator alarm, a MOSFET load-cutoff switch, an external fan, or a binary counter for metering applications. The LT2940 is offered in commercial and industrial versions, supporting operating temperature ranges from 0 to 70C and -40 to 85C, respectively. It is available in RoHS-compliant, 12-pin 3 x 3mm DFN and 12-lead MSOP packages.

S-2000AN Isolator Measures Small Magnetic Fields
Newport has introduced the S-2000AN Stabilizer Non-Magnetic Vibration Isolator. The S-2000AN is suitable for applications where the measurement of small magnetic fields would otherwise be impacted by traditional magnetic-steel isolators. It provides a 1Hz vertical-resonant frequency, a vertical-isolation efficiency of 98 per cent at 10Hz and a load capacity of 2000lb (907.2kg). It is suitable for isolating optical tables such as Newport's RPR-N tables or platforms, which support large vacuum chambers or other heavy instruments used in materials-research applications.Newport has quantified the magnetic impact of the S-2000 Stabilizer isolators, allowing customers to understand their required level of performance and potentially save thousands of dollars in equipment costs. Warren Booth, product line manager at Newport, said: 'In extreme applications where it is essential that all magnetic materials be removed, the S-2000AN is the best choice due to its aluminium and 316 SS construction. 'In our tests, our AN version induced only a 1.2nT change in measured magnetic field over a distance of 0 - 2ft (0 - 609.6mm).
'This compares with more than a 35nT change for traditional magnetic-steel isolators. 'Our standard S-2000A induced a 4nT change in the measured magnetic field, which means for some "non-mag" applications, our standard S-2000A may provide sufficient magnetic immunity, allowing our customers to save nearly USD10,000 (GBP6,680) on isolation equipment compared with competitive offerings,' he added.
In addition to superior isolation performance and quantified magnetic impact, the S-2000AN features Newport's Safelock mounting clips, which secure the isolators to the bottom of any Newport optical table, improving the performance, stability and safety of the system. Available in several popular heights ranging from 16 - 28in, the new vibration isolator is equipped with precision pneumatic re-levelling valves and float-height indicators.

EOS To Show Laser-Sintering System At AAOS 2010
EOS will display orthopaedic applications and an Eosint M 270 Direct Metal Laser Sintering system at the American Academy of Orthopaedic Surgeons (AAOS) meeting, from 9-13 March in New Orleans. The company will also present new process and quality enhancements for its manufacturing equipment. EOS plastic and metal laser-sintering systems are used to create devices, implants, ortheses, prostheses, surgical equipment and instrument prototypes.The systems allow medical designers to tailor-make parts that serve the individual needs of doctors and patients. In addition, laser-sintering enables engineers to create complex geometries such as porous surfaces that encourage osteointegration, and implants with mesh or scaffold structures that are lighter and more comfortable for patients. Materials available from EOS for orthopaedic applications include polyamides, a high-performance PEEK polymer, stainless steels, cobalt chromes and different titanium grades.
Recent developments that EOS will highlight at AAOS are new end-to-end quality assurance and manufacturing-process controls. DMLS now features an Integrated Process Chain Management module to ensure documentation of materials and processes. In addition, plastics laser-sintering systems now include as an option Part Property Profiles (PPP), which offer designers constant access to standardised property profiles and corresponding material values.
As a result, the PPP enables manufacturers to choose, from predetermined settings, the approach that is most cost-effective for their needs. Bestinclass, a micro-machining company, will also exhibit at EOS's booth and will display machined parts and offer technical background. Bestinclass provides post-processing, including fine surface finishing and polishing for laser-sintered metal parts. Several EOS customers that supply orthopaedic services will also exhibit at the AAOS meeting.
LMT Launches Shrink Toolholder System
LMT has developed a ready-to-run shrink-fit assembly toolholder system for CNC milling and turn milling. Suitable for the tool spindles of machining centres and driven tool units on turn-mill centres, the ISG 1000 bench-top unit allows users to overcome problems associated with the more traditional collets and hydraulic chucks. The portable unit measures 390 x 310 x 640mm, is powered from a three-phase plug-in source and will accommodate straight shank tool sizes between 3mm and 16mm diameter by up to 290mm in length.Shrink-fit technology is said to provide a simple way of mounting milling cutters, drills and taps into a toolholder/backend and also provides advantages in the machining process. For instance, it creates a higher rigidity set-up between the machine spindle bearings and the tip of the cutting tool. Run-out at the tool tip should be less than 0.003mm total indicated run-out (TIR), which ensures a more effective rate of feed per tooth can be applied due to the more even loading.
This is especially important on small-diameter or long-series tools. Longer cutting life also results with improved levels of accuracy and surface finish being achieved. In addition, shrink-fit tool assemblies are better able to cope with acceleration of modern spindles and influence of centrifugal force that can allow a normal toolholding arrangement to suffer from slippage in the collet and even tool drop-out. The ISG 1000 unit takes less than 20seconds to heat the nose area of the toolholder through its 6.5kW induction heating coil.
The cutting tool shank is positioned in the holder and is retained as a single unit in the holder as it contracts under cooling. The speed the cooling process, included in the ISG 1000 package is a cooling adapter that enables the heat generated to rapidly dissipate via a series of strategically positioned heat-sink fins. Also included in the LMT UK package is an interchangeable disc, clamping ring and protective gloves.
Controller Measures And Doses Small Liquid Volumes
Burkert has introduced the Liquid Flow Controller (LFC), which integrates a sensor, control electronics and proportional valves. The LFC accurately measures and doses small volumes of liquids with nominal flow rates of 10-600ml/min (0.6 to 36 litres per hour) with a 1:10 measuring span. Thanks to its fast and accurate flow-rate measurement, the LFC is suitable for the dynamic control or metering of liquids such as deionised or demineralised water, methanol or low-viscosity oils.The LFC can, therefore, be used in a number of industrial applications, including heat treatment (by carburisation or endogas generators), testing, surface coating, cooling (machine tools), filling, packaging and, in combination with Burkert mass-flow controllers (MFCs), the simultaneous dosage of gases and liquids in atomising or sterilisation processes. According to the company, the LFC is an integrated, cost-saving solution for applications where several liquids or a liquid and a gas must be regulated simultaneously.
Previously, this type of control was comparatively complex, involving the use of individual components, which raised issues of cost and interfacing incompatibilities. However, the LFC features an integrated design that optimises the differential-pressure process for liquid flow-rate measurements to give precise, fast and repeatable measurements in a compact device. The company claims that the digital controller combines reliability and functionality with features such as flow-rate measurement inside the medium flow (without moving parts); configuration and diagnosis via a serial interface using free Burkert software; an integrated totaliser for consumption analysis; flexible interfaces (analogue/digital via fieldbus or RS232/RS485); configurable binary inputs and outputs; and the option of an IP65 version for arduous environments.
The LFC is based on the tested software, hardware and mechanics of Burkert's MFC series. The controller is said to be simple to install and can be accommodated in difficult locations, such as directly behind angled piping. The device is available as either a closed-loop controller with an integral proportional control solenoid valve (LFC) or as a flowmeter (LFM).
Celesco Sensors Offer Linear Measurement Up To 43m
Celesco's PT9000 cable-extension position sensors, available exclusively in the UK from Variohm Eurosensor, are suitable for heavy-duty, high-accuracy linear measurement up to 43m.

The standard version has 11 measurement range options from 0m to 14m, with an optional extended range to around 43m. The operating temperature spans -40C to +90C and the vibration rating is 10G at 2,000Hz. The best-position accuracy is 0.1 per cent of full stroke with repeatability to 0.02 per cent of full stroke.
Throughout the range, the drum-mounted durable plastic-hybrid precision potentiometer, with a 250,000 minimum rated cycle life, is factory configured for a choice of electrical output covering voltage divider, position/velocity output (with additional tachometer), 0/4-20mA and 0-10VDC. An incremental encoder version is also available with a positioning resolution from 10 to 250 pulses per inch of travel. Canbus- and Devicenet-compatible output versions may also be supplied.
Additional options include a redundant brush system that offers extra protection for dirty environments and a velocity-limiting system that prevents the cable from reaching damaging velocity during a free release. Up to seven electrical connection options are available for each output version - from plastic or metal connectors to fully pressure-tested, waterproof cable. To match application requirements, the PT9000 series is also available in a choice of powder-painted aluminium or 303 stainless-steel housings, with IP67- or pressure-tested IP68-rated protection from immersion in liquids.
Hazardous-area certification is also available and measuring cable options include further nylon-coated stainless steel, stainless-steel only or thermoplastic cable. The Celesco PT9000 series typically requires a 150mm width to install with a tolerance of misalignment between the cable fixing point and the housing. The design also caters for a choice of four with four cable exit options.
SGS Inspects China Pavilion Structural Welds
SGS Industrial Services has been awarded a contract to provide independent welding inspection for the China Pavilion in Shanghai, which is manufactured from 23,000 tons of steel. The China Pavilion has been constructed as part of the World Expo 2010 event. It is shaped like an oriental crown and is 69m tall. The building consists of a 30m-high roof, which is made of traditional wooden brackets symbolising China's 56 minority ethnic groups and a large steel structure requiring 23,000 tons of steel.Given the high number of expected visitors, the safety checks on the construction of the steel structure were of crucial importance. For this reason, SGS China was awarded the contract to provide independent technical inspection of the welds. The main target of SGS's third-party inspection was to verify that the welds conform to all the applicable quality standards. SGS China set up an inspection team of eight experienced and qualified experts responsible for identifying, analysing and eliminating failed welds.
Moreover, the SGS engineers ensured that the welds met defined quality standards. For the technical inspection work, the team of SGS experts conducted ultrasonic testing and magnetic particle testing. These are non-destructive testing (NDT) methods for the detection of discontinuities and corrosion in material. Conventional ultrasonic testing uses the principle of sending a pulsed beam of high ultrasound from a handheld transducer, which is placed upon the surface of the weld being tested.
This wave will be partially returned from spots with internal imperfections. By measuring this sound, a skilled engineer can identify the location and size of the discontinuity. For magnetic particle testing, a magnetic flux is sent through the ferrous material. At the location of the imperfection a leakage field is created. This attracts metal iron dust, which is sprayed onto the surface. SGS's inspection work took seven months and was completed in January 2009.
Ball Bearing Provides Sealing And Lubrication
Baldor Electric has launched a Dodge-brand mounted ball bearing incorporating sealing and lubrication functions. Dodge Ultra Kleen ball bearings can extend equipment lifetimes in harsh, washdown-duty operating environments, such as food and beverage processing. They employ a 100 per cent stainless-steel bearing insert and feature a patented sealing system and a ball retainer that maintain lubrication and prevent washout in wet operating environments.The new sealing system, Quadquard, consists of two patented features: a triple lip seal and a rubberised flinger. The triple lip seal offers three points of contact, keeping the lubricant in and contaminants out. This design maximises sealing with a minimal amount of drag, according to the company. The rubberised flinger is a moulded nitrile rubber component that is bonded to the flinger surface, providing an additional barrier to contaminants.
The rubber-baffled design on the external surface of the flinger enhances the removal of liquid as it rotates, while grease chambers on the internal surface of the flinger prevent lubricant from exiting the bearing. A new two-piece ball-retaining cage, called Maxlife, creates a grease compartment around each of the rolling elements. The compartments provide constant contact between ball and grease so an oil film always exists to prevent wear and to minimise friction and heat.
The compartmental construction holds in the grease and prevents it from being washed out. This design extends the life of the bearing and requires less frequent relubrication than standard designs, according to the company. A 65-degree spacing of the setscrews is intended to provide excellent locking force without compromising the strength of the inner ring, while a stainless anti-rotation pin prevents the insert from rotating in the housing.
The stainless housing is made with 300 grade steel. Polymer-housed versions have an added antimicrobial agent that retards bacteria and fungus growth. Both housing styles contain all-stainless hardware and fittings, as well as stainless-steel inserts. All versions feature a solid, flat base that has no cavities or areas that can provide a site for bacterial growth. For additional protection, the housings are machined with a groove to accept a snap-on polymer end cover to cover exposed, rotating shafts and create safer working conditions.
These covers incorporate a drain hole to prevent moisture build-up. Dodge Ultra Kleen bearings are offered in a variety of stainless-steel and polymer housings. The range is available in a range of imperial and metric sizes, from 20mm to 50mm.

Featuring a fully factory configured system, the 3000 Program 19in RMU comes with a communication module, control module for eight cabinet handles, a sensor module (for temperature or vibration monitoring, for example) and unit power supply ready to fit in plug-and-play mode.The standard Elm 1U rack module is quickly installed and connected to the sensors, cabinet handles and to other cabinets, speeding up the process of enhancing cabinet security. The Program 3000 Elm system is designed to meet the needs of modern security systems both in terms of personnel access, control/logging procedures and to handle increasing needs for internal cabinet environmental monitoring/control. It is based on Can-Bus technology and the EMKA Swinghandle program.
The Elm modular network system can be used for monitoring, controlling and reporting of all relevant cabinet events on the network. The system can be used as a simple monitoring system (for example, individual access, temperature, humidity, smoke) and extended up to a complex system, including message sending and activation of control functions suitable for on-line server cabinets or to provide server room security.
Within its own function every module is reprogrammable. The exchange of sensitive data is made via an encrypted code. The Elm system consists of different functional units connected via bus only. Up to 64 modules can be connected to the bus within a maximum 1000m length. The modules can have the same or different functions. A record of the last data status during a power shutdown is made inside the module and it is possible to make a software update or to programme the modules via the bus.

Infinity P4-A Panel PC Works In Harsh Environments
DSM Computer has unveiled an additional Infinity P4-A panel PC, which, thanks to its IP65 front, is suitable for use in harsh environments. The modular and fan-free construction of the Infinity P4-A permits a range of possible applications and offers an expandable and cost-saving alternative to traditional panel-PC systems. The Vesa assembly arm allows the P4-A standalone system to be integrated quickly and easily, according to the company.The arm makes the system particularly suitable for building automation applications, for visualisation tasks with point-of-interest/point-of-sale applications, for machine and plant control and for logistics and transport management. The development of the P4-A system involved particular attention to low heat loss. This is achieved through the use of the Intel Atom N270 processor with the Intel 82945GSE chipset and the ICH7M Southbridge. The processor is clocked with 1.6GHz.
The thermal design power (TDP) of the Intel Atom N270 consumes just 2.5W and less than 50 per cent of expensive ultra-low-voltage (ULV) processors. The integrated 1Gb main memory can be expanded to a maximum of 2Gb. To further reduce power consumption, the 38cm (15in) Infinity P4-A panel system uses a light-emitting-diode (LED) backlight. This allows the display computer with specified 250cd/m to consume up to 20 per cent less power compared with traditional computers. Thanks to the CCFL backlight, the service life at low temperatures is higher than for normal CCFL display solutions.
The panel computer also has an energy-efficient power supply. A 115-230VAC power pack is integrated in the system with a 24VDC power supply available as an option for the user. The Infinity P4-A provides an internal mini-PCI Express slot and a maximum of two PCI slots for various plug-in cards. Interfaces such as eight USB 2.0 (two of which are on the front panel), two local-area networks (LANs) and one audio are accessible from the rear of the computer. The input and control of the panel PC is made using the ELO touch function.
The system already contains a 2.5in (6.4cm) hard disk for data storage. An optional solid-state drive and a Compact Flash slot can be installed. The system is designed for operation in the 0-45C temperature range (+50C with fan). DSM ensures the long-term availability of the panel system for four years. The computer is subjected to a burn-in test for at least 48 hours and is delivered with a two-year guarantee.
Optoisolator Delivers Up To 16kV Isolation At 2Mbd
Optek's new OPI1268 16kV high-voltage optical isolator, available via Pacer, delivers AC and DC voltage isolation up to 16kV while achieving digital data transmission rates of 2MBd. The OPI1268 UL-recognised high-voltage optoisolator is designed for power isolation in high-voltage PC board circuits in industrial electronics systems, medical electronic equipment and office machines.The output IC detects the incoming optical signal and converts it to a proportionate current, which is fed through a high-gain linear amplifier and compensated for temperature, current and voltage, resulting in a stable digital output with an open collector inverter configuration. The OPI1268 optoisolator combines a high-efficiency gallium aluminium arsenide (GaAlAs) light-emitting diode (LED) with a peak wavelength of 850nm, optically coupled to a Photologic photodiode in the output IC.
Forward current (IF) is 10mA typical/50mA maximum, with typical propagation delays (tPHL-tPLH) less than or equal to 500ns. The creepage distance/air path is 0.970in (24.64mm) and the devices are UL recognised under file E58730. Packaged in an opaque high-dielectric plastic housing, the OPI1268 device measures 27.94 x 6.35 x 8.89mm and has a five-lead configuration (cathode, anode, Vcc, output and ground). The operating temperature range is from -40C to +100C. Data and samples are available now from Pacer.
PS900 Soldering System Reduces Micro Cracking
OK International has launched a soldering system for PV tabbing and bussing applications that reduces micro cracking. The PS900 with specially designed hoof-tip geometry optimises the power delivered to the solder joint, while its temperature-sensitive heater ensures low-temperature soldering, thus minimising thermally induced stresses on cell surfaces. The system incorporates the company's patented Smartheat technology, which will produce and maintain a specific, self-regulated temperature with a heater that does not require calibration and that responds directly to thermal loads.There are two suitable solder alloys utilised for solar-cell soldering applications: the Sn96Ag4 with a melting point of +221C or the bismuth-containing Bi58Sn42 with a melting point of +138C. Proper soldering will result in an intermetallic layer that is 1-2um, which demands precise time and temperature control during the solder-joint formation. Hoa Nguyen, vice-president of technology, said: 'The ability to solder at low, controlled temperatures within a short time window reduces the stresses on the cells and the likelihood of micro cracking.
'Connection temperatures must be maintained below 300C. 'This new system employs Smartheat technology to produce thermally controlled, high-quality solder joints,' added Nguyen. The micro cracking of delicate solar-cell substrates is a common defect that can occur during PV tabbing and bussing soldering processes. Reducing the soldering temperature to a minimum prevents the cells being subjected to mechanical or thermal stresses. During the soldering operation, the differential thermal expansion of the copper and the silicon elements can occur at temperatures greater than +300C.
This differential can result in the formation of micro cracks that may not be detected during the manufacturing process and result in a reduced field lifespan. The OK Smartheat PS-900 soldering system with a specially designed STV-DRH40 hoof-tip geometry optimises the power delivered to the solder joint, thus providing high-performance efficiency with increased tip life, according to the company. The temperature-sensitive 'T' heater series ensures low-temperature soldering and thus minimises thermally induced stresses on the surface of the solar cells.

Warner Provides Brakes For Large Wind Turbines
Warner's ERS series of spring-engaged, electrically released brakes is helping to further the growth of wind energy by providing the braking function for large turbines under maximum wind conditions. The modified brakes operate as pitch brakes in wind-turbine applications that require static holding power and the ability to withstand high-inertia dynamic stopping in emergency situations. They are mounted outboard of an inductive encoder, which is fitted to the back of a motor to position the blades to the correct pitch.
The ERS series units have a one-piece design, which is fully enclosed and painted to withstand extreme environmental conditions, such as salt spray, condensation and water. In normal operation, the ERS brakes function as a static brake to hold the blades from rotating in a power-off situation, during routine maintenance or for inspection purposes. However, the design specification produced for one manufacturer requires the brake to also be able to make 1,000 fully loaded dynamic stops during its service life.
The largest in the Warner Electric ERS series, the ERS68 brake offers 100ft/lbs of static torque, with a maximum of 2,000rpm and a brake release time of 0.2sec. The ERS68 weighs 5kg and has been tested to a capacity of more than 20,000 fully loaded dynamic stops, surpassing the design specification by a factor of 20. Warner Electric has also developed a series of static holding brakes as part of its comprehensive package for wind turbines.
The static brakes meet the design criteria for controlling yaw when the wind-turbine nacel is positioned into the wind. For this technically simpler application, the yaw brakes are also mounted on the back end of a motor. Solutions for other smaller wind-turbine applications have also been solved using Warner Electric brakes. These include the Vertical Axis Wind Turbine and the Wind Wall, an urban wind turbine designed to be sited on roofs or on the sides of buildings in windy city areas.

Parker Releases Conversion Kits For CCV Solutions
The Racor division of Parker Hannifin has extended its range of crankcase-ventilation (CCV) solutions with new conversion kits and fittings. Two conversion kits are available, which enable a CCV8000 assembly to be converted to a CCV12000 model, improving the filtration of harmful exhaust gases at minimum cost. To simplify the installation of the latest CCV products, Parker has developed 90deg fitting adaptors, which allow hoses to be connected to the crankcase filter quickly and easily.By installing one of the Parker Racor CCV55613-08 and CCV55613-10 conversion kits, users can increase the filter media of a CCV8000 system by 60 per cent, effectively turning it into a CCV12000 assembly. This makes it simple and affordable to achieve extra capacity in engines that are not easily accessible. Like all Parker Racor CCV systems, the kits are compact and durable, combining coalescence and crankcase-pressure control. The kits are easy to install, especially when used with Parker Racor 90deg fitting adaptors.
These components allow CCV assemblies to be installed in tighter applications, where using a straight barbed fitting may be difficult. Hoses can be routed vertically to the crankcase filter and, once in place, can be locked in any orientation. Added benefits include reduced oil consumption and extended service life for turbos and aftercoolers, minimising maintenance requirements and cutting operating costs for end users.
Test Kit Assesses Grease Conditions In The Field
SKF has develop a complete grease test methodology to assess grease conditions in the field. For fresh and used grease, the test kit enables fast tests on consistency, oil bleeding and contamination analysis. These tests enable users to take immediate action, saving time and reducing samples required by the laboratory as part of a structured lubricant analysis plan.The new portable TKGT 1 grease test kit is designed as a quick assessment tool for use throughout the engineering sector. The system uses a four-step process: collecting information, collecting samples, grease tests and reporting. No specialist training is required to perform the tests as full instructions are provided, complete with detailed test protocols and report templates. No harmful chemicals are required and only small samples of the grease are needed to perform the tests.
The SKF grease test kit can be used with fresh- or used-grease samples. For fresh grease, the kit can help establish the remaining operating life of the grease by assessing its mechanical properties. It can also test the quality of the grease and check for colour or consistency changes between grease batches. It helps to assess whether these inconsistencies are within acceptable limits. For used-grease samples, it can help assess the degradation status of the grease to identify necessary relubrication intervals, which can be adjusted to reflect real conditions.
It can test the physical changes of the grease, such as colour, and help to understand the root causes for these changes. The test can also support decision making on the appropriate grease for a certain application by helping the user to compare different greases. Despite 80 per cent of bearings being lubricated with grease, the majority of lubricant analysis techniques in the field have been traditionally limited to oils, according to the company. SKF has developed the TKGT 1 grease test kit and accompanying methodology, offering customers a new approach to in-field grease status assessment.

Software Increases Machine-Tool Accuracy
Heidenhain has introduced Kinematicsopt software, which compensates for the effects of rotary table/swivel-head spatial error and for geometrical positioning and component error in machine axes. The developments are expected to have a significant impact on multi-axis machining applications - in particular, eliminating relatively long and complicated set-up times for complex, extended-cycle workpieces subjected to five-axis machining.Using a Heidenhain touch probe, the new Kinematicsopt software will automatically measure a machine's rotary axes - whether rotary table, tilting table or swivel head - thus providing users with a quick, easy-to-use fixed cycle that will ensure machine positioning is consistently accurate. Regular use of the five-minute cycle will therefore provide users with an automatic route to check axis positioning and to adjust accordingly.
From the measured values, the Heidenhain TNC control system will calculate static tilting accuracy and the software will automatically minimise any resulting spatial error. At the end of the measurement process, the system will automatically store the appropriate machine geometry in the respective kinematics table or signal an alarm if the measured deviation is beyond a preset limit.

WEG Designs Slip-Ring Motor For Compressor Testing
WEG has supplied a 45-tonne, 14,000kW, 10,000V high-voltage slip-ring motor for the testing of large radial, axial and geared compressors at the Man Turbo Oberhausen plant. Designed and manufactured by WEG to customer specifications, the M-Line slip-ring motor has a robust design that enables it to provide reliable operation under severe test conditions. The motor has two conical shafts, allowing the connection of steam turbines or expanders to the second shaft end, raising its mechanical transfer rating to 20,000kW.The largest motor ever built by WEG is a slip-ring machine, which is used in a wind tunnel for testing aircraft at high Mach numbers. This motor, a 27,000kW, 12-pole, 11kV machine, is 7m (l) x 5m (w) and weighs over 93 tonnes. The increased power required for its operation meant that it needed its own 132kV grid connection. WEG was able to provide a total solution based around this requirement, by supplying a 35MVA 11/132kV transformer with auto-tap changer. The Man Turbo motor is a force-cooled unit that is rated S1 - 100 per cent 14,000kW at F/F rise, from 1,500rpm down to 750rpm, and weighs 45 tonnes.
A slip-ring motor was specified by Man Turbo. Slip-ring motors are suitable for Man Turbo's test purposes, as they do not suffer from any torque pulsations in their drive train. The flexible M-range design enables the motor specification to be tightly tailored to specific customer specifications. The Man Turbo motor is designed with two conical shaft ends, to facilitate tests in excess of the normal capacity of the motor. In these tests, the second of the conical shafts is attached to a turbine or an additional motor to deliver the additional power, raising the mechanical transfer rating of this motor to 20,000kW.
Speed control of the motor is carried out by a liquid rheostat. This unit has two tanks for part- and full-load testing. The speed range is 0 to 1,500rpm, with normal operating in the 50 to 100 per cent range or 750 to 1,500rpm. Within this speed range the motor operates with constant torque. The testing procedure was successful, resulting in further purchases of WEG equipment, including motors and generators.

DSB Uses 6KQs For 'Ethernet Backbone' In Trains
Danish state rail operator DSB is using 6KQ Ethernet switches from Garrettcom to give its trains an 'Ethernet backbone'. The 6KQ switches realise VLANs for various internal train systems, providing network connections for in-carriage IP-enabled security and surveillance equipment, infotainment systems and passenger-counting technology. The 6KQ met DSB's need for a compact, cost-effective 10-port Ethernet switch with gigabit bandwidth, in a hardened package with the assurance of EN50155 certification for railway applications.A 6KQ switch is mounted in each carriage and the switches are linked in a bus topology, providing an Ethernet backbone along the length of the train. The switches provide central points in each carriage into which the IP-enabled equipment can be readily connected. The backbone is also connected to a WLAN gateway, responsible for handling the network traffic between the train and the outside world. Network packages are transmitted and received via an antenna installed on the roof of the carriage.
The switches are all powered from an auxiliary 110V DC system, installed through each coach, and are managed using Garrettcom's MNS-6K software, making it simple to realise optimal network traffic for all subsystems. Train and network operators are looking to provide passengers with an improved journey experience, focusing on safety, security and efficiency. Much of this can be addressed with modern CCTV and video-recording technology. CCTV cameras mounted in the carriages and linked to video recorders form an effective surveillance system that acts as a deterrent against crime and anti-social behaviour, including attacks, vandalism and graffiti damage.
The CCTV cameras are linked to the video recorders over Ethernet via the 6KQ switches. Log files of the recorded data are transmitted from the video-surveillance system server to a central office via the WLAN. The WLAN also transmits the train's position information in real time. It also provides passengers with a free internet connection as part of the infotainment system. Ethernet-enabled cameras are mounted in the carriage doorways and register the number of passengers entering and exiting the train at each station.
Not only does this indicate when carriages are full, but the data generated is also being used in statistical analysis to identify passenger trends and behaviour and so help in the planning of improved train schedules. Key in the choice of the 6KQ switch for this application was its ability to be powered directly from the 110V auxiliary supply, eliminating the need for costly voltage converters. The 6KQ also meets the requirements of EN50155, the standard for electronic railroad applications. EN50155 introduces stringent demands for reliability, covering humidity, extended temperature range (-40C to +85C), shock, vibration and power fluctuations.
In addition, EN50155 prohibits the use of fans in train electronics: only passive cooling technologies are permitted. The 6KQ meets all these requirements. In particular, it is sealed to IP53 for dust- and water-resistance and features a unique case design for maximum heat dissipation, eliminating the need for fan cooling. EN50155 as a precautionary measure suggests the use of protective coatings for PCBs in electronic products to counteract corrosive atmospheres that are often present in railroad applications. Garrettcom offers conformal coating as an optional add-on to ensure continuous operation.
The 6KQ is a rugged field switch developed to meet user requirements for small form-factor gigabit Ethernet switches in demanding applications. It offers a maximum of 12 ports and can be configured with user-selected combinations of 10 and 100Mb and gigabit fibre ports of any connector type. Copper port options include 10/100/1000 RJ-45, as well as up to eight 10/100 PoE (power over Ethernet) ports. To meet the needs of demanding industrial Ethernet applications, the 6KQ can handle stressful workload mixtures of high-burst data traffic and priority streaming traffic.
