ESAB Introduces Manual Cutting Packages

ESAB has introduced two new models in its Powercut line of manual cutting packages. The lightweight portable Powercut 900 and 1600 packages are designed to make cutting easier and more economical due to design features that simplify operation, reduce setup time and enhance consumable life. The Powercut models are said to offer the highest speeds and thickness capabilities in their class, as well as high duty cycles. Through a combination of long parts life, high speeds and simple torch design, they give the lowest cost per metre of cut of any machine in their price class, claims ESAB. The power source is contained within a durable, damage-resistant external housing that is also corrosion and weather resistant. The sensitive internal electronics are suspended from the aluminium frame and insulated from shock and vibration. Silicone-sealed switches are also immune to corrosion and dust/dirt infiltration. A quick-disconnect torch disconnects from the machine simply, allowing easy disman

Spherical Rod Ends Suit Aggressive Environments

Elesa's BJT series of M6 to M14 glass-reinforced technopolymer spherical rod ends are suitable for rotary, oscillating and linear movements, even in particularly aggressive environments. They can also be used where water or humidity, fine dusts, dirt, fabrics and machining residues are present. The shaft rotary movement can take place directly on the inner diameter of the spherical cap, made of self-lubricating materials - they are designed to require zero maintenance with low wear and to absorb vibration and stress while minimising noise. They have high mechanical strength and low weight, while being corrosion resistant, even in aggressive industrial environments. The BJT series is maintenance free and especially good at compensating misaligned linkages and absorbing vibrations and transverse stresses with low noise. Applications are likely to include sensor mechanisms, gas struts, rod-control linkages, motion control - low-power movement transmission and pneumatic actuator syst

Facom Introduces Roller Cabinets for Workshops

Mail-Sorting System Implements PBC Linear Actuator

Recently, print-mail automation specialist Capstone designed its large-scale Autoviri mail sorting and packing system, which included a PBC Linear actuator, to perform a critical transfer task. After working through some initial design challenges, Capstone, with PBC Linear's support, was able to produce an efficiently automated system that processed 1,000,000 pieces of mail per shift without shutdown or manual intervention. The complete Autoviri packing system performed 99 per cent complete packing automation from beginning to end. PBC Linear was contacted to provide a linear motion solution to transfer the mailing trays into the package-sleever. Capstone required a system that was robust, could operate at high speeds and could run 24/7 with virtually no maintenance upkeep. The linear motion system also had to fit into the already specified profile Ellison had specified. Based on the initial loading and motion-profile requirements, Ellison chose PBC Linear's MT series linear

Leisure Centre Pool Set to Save with ABB Drive

A leisure centre in Sittingbourne, Kent, is set to save GBP4,000 a year on the costs of air handling for its swimming pool following a trial with an ABB low-voltage AC drive. The Swallows Leisure Centre is operated on behalf of the local authority by Serco Leisure, which was concerned by the energy use of the air-handling unit (AHU) in the upper pool area. To deal with a condensation problem in the pool hall, this AHU was being run 24 hours a day, 365 days a year, with no control over its output. To improve this situation, Serco asked ABB Drives Alliance member Mid Kent Electrical (MKE) to investigate the application and determine any savings that could be made. To assess the application, MKE monitored the power being consumed by the existing 22kW supply fan in the AHU over a period of one week, revealing that the average power consumption of the fan during the period was slightly more than 19.5kW. The second stage of the trial involved replacing the star/delta starting system with a

Sensor Enhances Reliability of Fluidic Systems

Sensirion has introduced the LG01 micro flow switch for ultra-low liquid flow rates and bubble detection in bio-medical and process control applications. The sensor is said to make fluidic systems more reliable by enabling the detection of liquid flow within the range of a few millilitres per minute and less. For such measurements, the sensor offers a response time of less than 100ms. Its output signal of either 0V or 5V indicates whether the current flow rate is above or below the specified flow switch level. At continuous flow rates above this limit, the identification of air bubbles within the flow channel is equally consistent. Maximum flow rates are accepted up to 220ml/min. Fluidic connections can be made via 1/4-28 standard fittings, suitable for connecting plastic tubing with outer diameters of 1/8in (3.2mm) or 1/6in (1.6mm). Barb connector adapters are available as an alternative. The small and light sensor is designed for integration into bio-medical applications and gene

Three-Way Sorting Capability for Food Processors

Key Technology has introduced a three-way sorting capability on its Manta automated sorter for the food industry. Featuring two ejector systems, three-way sorting allows food processors to automatically eject product that can be reworked and recovered separately from material sent to waste, typically foreign material (FM). Good product continues through the camera/laser sorter unaffected as usual. Key Technology said this capability allows processors to produce a high-quality finished product without losing recoverable off-grade product to the waste stream or requiring additional sorting expense to separately rework product. Manta with three-way sorting is suitable for processors that want to remove foreign material as well as valuable off-grade product from their primary product. For these processors, traditional two-way sorters require the reject stream be re-sorted using manual inspection or a second automated sorting system to recover valuable off-grade product. Depending on the

Wedge-Locking Washer for Demanding Applications

Heico Fasteners UK is to showcase its Heico-Lock anti-vibration bolt securing system at the Subcon 2011 event. The high-quality wedge-locking washer is suitable for demanding bolt-fastening applications and meets the requirements of the DIN 25201-4 standard and DIN 65151 'Junker' vibration test. Heico-Lock wedge-locking washers positively lock fasteners using tension instead of friction. The pre-assembled pair of washers have inclined clams on the inside and radial 'teeth' on the opposite sides. Tightening of the bolt leads to a gripping action of the teeth, thus seating the surfaces. Once in place, movement is only possible across the face of the cams. Working together, both sides of the locking washers combine into a fastening system that prevents loosening of joints by shock and vibration.

Material Storage/Retrieval Tower for Punch Presses

LVD has introduced a compact material storage and retrieval tower (CT-P) for Strippit turret punch presses, including Strippit V, VT, M and VX series models. The space-saving CT-P system is said to provide increased productivity by facilitating optimal material flow and unattended operation for uninterrupted punching. The system provides full capabilities for loading, unloading and storage of raw material and finished parts, enabling automated production from stored raw material to stacked finished parts, as well as providing increased storage capacity. The CT-P unit facilitates unmanned, 'lights out' production in a compact cell environment. The tower is offered in two configurations: six-pallet and 10-pallet units. The system can handle workpieces as large as 2,500 x 1,225mm and sheet weights up to 90kg with a maximum load/unload pallet storage capacity of 2,500kg.

Separable Bearings for Wind Turbine Gearboxes

SKF has introduced its separable high-capacity cylindrical roller bearings to support high-speed shafts in wind turbine gearboxes. Equipment manufacturers can add advanced technology and increase system reliability by incorporating these bearings within gearboxes and turbine units, the company said. For wind farm owners and operators, the ability to reduce gearbox failures and turbine downtime can minimise operating and maintenance costs, helping to lower cost per kWh and increase profitability. The separable high-capacity cylindrical roller bearings from SKF combine the advantages of conventional cylindrical roller bearings and SKF high-capacity cylindrical roller bearings. They are sized to match standard original bearings, yet feature extra rollers for increased load-carrying capacity. In addition, they offer the ability to separate the inner ring from the rest of the bearing components without the risk of the rollers becoming disengaged. Conventional bearings used to handle minim

Trumpf Introduces Electric Punching Machine

The Trupunch 3000 electric punching machine from Trumpf offers efficient, skeleton-free punching made possible by powerful nesting software combined with the option to rotate parts and scrap. The result increases reliability in several areas, according to the company. For example, parts are cleanly separated from the skeleton, the operator no longer needs to remove leftover material from the table, and the machine automatically separates finished parts from the scrap. Production costs are also reduced in the region of 10 per cent because less material is required. The Trupunch 3000 introduces Trumpf's electric punching head, which is said to bring several benefits. It is quieter in operation and uses little power in standby mode. When it is punching it is more energy efficient, using 2kW of power per hour less than its predecessor. The punching head is also more productive, according to Trumpf. Tools are rotated at higher speed giving more benefits - threads are formed quicker, f

Linear Technology Offers LTC3833 DC/DC Controller

Linear Technology has introduced the LTC3833, a high-frequency controlled on-time synchronous step-down DC/DC controller with differential output voltage sensing and clock synchronisation. The controlled on-time, valley current-mode architecture forces a very fast transient response by increasing its operating frequency during a transient event, allowing the LTC3833 to recover from a large load step in only a few cycles. Its 4.5 to 38V input range encompasses a variety of applications, including most intermediate bus voltages. Strong onboard N-channel MOSFET gate drivers allow the use of high-power external MOSFETs for high load current, up to 25A in applications with output voltages ranging from 0.6 to 5.5V, making it suitable for point-of-load requirements. The LTC3833's differential amplifier provides true remote output voltage sensing of both the positive and negative terminals, enabling high-accuracy regulation independent of IR losses (up to +/-500mV) in trace runs, vias an

Custom Design Service Targets Displays with Icons

GPEG's custom design service is suited to manufacturing segmented displays with icons, such as energy metering, marine electronics, industrial instrumentation, consumer products and readout displays. Using vertically aligned LCD technology produces a display with a good contrast ratio and wide viewing angles. Typically, the contrast ratio is more than 800:1 with viewing angles of 80/-50deg up/down and -80/80deg left/right. The manufacturing process does not require a traditional black mask, thus reducing the complexity of the display. Using a white LED backlight ensures a bright, sharp image with an extended operating temperature range of -20 to 80C. The displays also work well in direct sunlight. The standard display features a black and white image, however alternate colours can be produced using colour films or a different coloured LED backlight.

Thermal Imaging Cameras for Heavy Industrial Work

Small Brushless Servomotors Have High Peak Torque

Inmoco has extended its Exlar range of SLM brushless servomotors with a new 180mm frame size that offers users high levels of peak torque (69Nm) from the smallest package available. This performance is the result of T-LAM stator technology, which is employed across the SLM range, providing 35 to 70 per cent more torque and higher efficiency than conventional high-speed brushless servomotors with equivalent frame sizes. The SLM servomotors are a range of motion products designed to offer the OEM good performance, quality and customisation possibilities. The torque performance and efficiency provided by the motors is the result of a design harnessing a combination of high-density Neodymium iron boron magnets and the limited heat-generation qualities inherent in the T-LAM segmented stator design. In particular, the elimination of end turns in the stator and the use of thermally conductive potting removes the parts most susceptible to failure in a traditional stator. The design also be

NGV Project Utilises Mettler Toledo Systems

Gas Filter Sleeves Resist Mechanical Fatigue

Porvair Polypropylene Gas Filter (PPGF) sleeves are made from proprietary binder-free, polypropylene fibre filter media, designed to provide a highly permeable matrix with low resistance to gas flow. According to Porvair Filtration Group, the filtration efficiency of the PPGF sleeves has been extensively tested and confirmed to be fully compliant with the requirements of T-SP-E-13. This standard requires a gas filter to achieve 95 per cent efficiency at the required particle size stated. The PPGF material has a gravimetric efficiency of 99.95 per cent when tested over a size range of 0.75 to 10 micron. PPFG filter sleeves are manufactured in a seamless circular method using a mandrill former, upon which the needling is performed. This process enables a filter media with a high void fraction of approximately 75 per cent to be produced, which provides the benefit of a high relative dirt capacity. Porvair claims the material's compressive nature enhances filtration because, as it ne

Protomold Aids Design of Circuit Breakers

In a recent project to design a range of moulded-case circuit breakers, ABB SACE used Protomold, a Proto Labs service, to make various parts for the Formula and Tmax XT models. Protomold not only produces individual injection-moulded prototype parts, but can also supply relatively small batches of production injection-moulded parts faster than conventional suppliers. Proto Labs offers two services: Firstcut produces CNC precision-machined one-off and low-volume prototype components, while Protomold provides rapid injection-moulded parts in batches from 10 to 10,000 in number. Both operations employ powerful computers and proprietary software to help designers optimise a part for production, meaning that even customers with absolutely no manufacturing experience can still use Protoquote, the company's online automated ordering system. The Protomold online ordering process is available in five European languages, including Italian, and is designed to be straightforward and easy t

Tool Monitors SF6 Insulation in High-Voltage Tools

Vaisala has introduced its Multiparameter Transmitter DPT145 for the online monitoring of SF6 insulation in high-voltage equipment. The DPT145 combines online dew point monitoring with pressure measurement, enabling assessment of the condition of SF6 insulation continuously and in real time.

The direct normalised pressure measurement of the Vaisala DPT145 detects leakages immediately, while online dew point measurement provides early warning on moisture issues, which affect the insulating properties of the gas and cause rapid deterioration. The Vaisala DPT145 is capable of providing online monitoring of seven different parameters at once. It measures dew point, pressure and temperature directly, and provides calculated values for density, normalised pressure, dew point i

Beko Discusses Evolution of Compressed-Air Systems

Beko Technologies discusses the evolution of compressed air and how it is generated and treated. 35 years ago, the salesperson selling compressed-air generation and treatment equipment had very few tools at his disposal. Many systems were oversized because there was no low-cost means of deciding the size of the system, so educated guesswork was used. The only scientific way to determine component sizes was to note all equipment consuming compressed air and then observe the cycles or take a usage factor - if using a drill it is unlikely that the drill would be in constant use as the hole would normally be drilled to insert a screw or bolt. Even doing this usually led to a calculation that would oversize a system. Filter manufacturers were still focusing on sterile air and process filters rather than compressed air. Dryer manufacturers were making fridge dryers with no great attention to power consumption or pressure drop and desiccant dryers were selected on capital cost rather than r

True Wastewater Pump Energy Costs Revealed

During a speech at the Pump Centre Conference 2011, Stefan Abelin from Flygt urged end users to do more to understand true pump efficiency in actual field conditions. Extensive measurements in the field have shown that end users' actual energy costs are often increased by as much as 30 per cent for on-off pump operation in wastewater, compared to clean water pumping. The costs are even higher for pumps with long duty cycles or those in continuous duty operation. Little effort is being spent on measuring and understanding true pump efficiency. There is a general lack of awareness of the key issues involved in efficient pump operations in the wastewater industry and an over reliance on minimum pump through-let size as a criterion for equipment selection. The pump industry has not yet taken on the task of developing test procedures for wastewater pumps that reflect 'real world' duty. Today the end user is left to assume that the same pump efficiency will be delivered in the

Ishida to Supply Poultry Processing Plant

The Meyn-Ishida alliance has won a contract for the delivery and installation of a complete wall-to-wall poultry processing plant adjacent to an existing factory for Wipasz in Poland. Wipasz, a Polish animal feed supplier, first diversified into poultry processing in 2010 with the acquisition of a 5,000-birds-per-hour facility. The first task of Meyn-Ishida will be to replace the existing live bird arrival system and to upgrade the current bulk pack operation with weighing and tray packing capabilities to enable it to produce a more sophisticated range of products. The next step will be to deliver and install Meyn-Ishida equipment for a new to build processing plant. Both steps will be accomplished during 2011-2013. Meyn-Ishida combines the poultry processing expertise of Meyn with the weighing, packing and end-of-line knowledge of Ishida to offer a full range of integrated systems and equipment. The alliance has already been awarded several international contracts, including fully i

Genevac System Improves ASE Workflow

Genevac has launched the Flip-Flop system, designed to improve post-Accelerated Solvent Extraction (ASE) concentration and preparation of samples. Using the double-ended Flip-Flop tube, samples can be collected directly from a Dionex ASE system. A Samplegenie adaptor with GC vial is then fitted. The tube is flipped over and placed into the Puck sample holder in a Genevac Rocket Evaporator and the cap removed. The samples are then concentrated directly into a GC autosampler vial. The Genevac Rocket Evaporator enables rapid concentration or evaporation of up to 18 Dionex ASE vials simultaneously. In addition, using Genevac's proprietary Samplegenie technology in conjunction with the Rocket Evaporator enables samples to be concentrated directly into an autosampler or storage vial, eliminating the need for manual sample transfer. According to Genevac, addition of the new Flip-Flop system completes the automation of transfers from ASE vials. Using this procedure eliminates manual tr

Heavy-Duty Joystick Controller for Arduous Tasks

Penny and Giles, a designer and manufacturer of position sensors, solenoids and joystick controllers, has introduced a heavy-duty, single-axis joystick controller to its JC6000 product range. It is designed to provide a higher-strength, return-to-centre joystick for use in arduous conditions or applications such as wheeled loaders and heavy plant machinery, where high across-axis loads can be an issue. The increased strength of the heavy-duty JC6000 has been achieved by redesigning the body casting, which the company claims has increased across-axis fatigue life by a factor of five. This heavy-duty version will also use a new gaiter, designed specifically to accommodate the increased strength of the body casting. It is intended to be used as an alternative to existing single-axis, spring-return joystick controllers, as both versions share the same panel-mounting detail. The new JC6000 heavy-duty joystick controller is available with long-life potentiometer track sensors with auxiliar

Point-and-Shoot CCD Camera Images Transient Events

The T-Cam from Specialised Imaging is a scientific CCD camera designed to enable high-resolution imaging of transient events. It is able to capture images of transient events at up to an 11-megapixel resolution. The ability to operate at shutter speeds faster than 1us eliminates motion blur. This, together with high optical sensitivity across a 12-bit dynamic range, enables the T-Cam to provide high image quality. The T-Cam is equipped with two trigger inputs that are capable of accepting trigger signals from almost any conceivable source. The SI Sure-shot velocity triggering system is also incorporated for use where this is appropriate. The Sure-shot system takes an input from two spatially separated detectors, allowing the camera to calculate the correct exposure timing, irrespective of the subject's velocity. Two independent customer-programmable pulse outputs are also included in the T-Cam to allow control of external lighting or other instruments. Combining robust, compact
