THEY CUT THE CABLE LINE Micro Plastics has lowered prices on their line of ADJUSTABLE CABLE CLAMPS. These adhesive-backed clamps are molded in black nylon 6/6 with a 94-V2 U.L. rating and allow for the easy addition or removal of cables and wires. Available in 5 sizes, ranging from .311" to 1" bundle diameters, they provide an easy open/close design and unlimited usage. See Catalog #38 for a complete line of nylon fasteners, with samples at no cost available on request. Visit Micro Plastics.
Precision to "die" for in beverage can making
In the world of beverage can manufacturing, the quality of the dies that shape each can directly impact manufacturing quality and productivity. Addressing the demand for more precise, longer-lasting dies, Pride Engineering developed the Model 30 Air Bearing Grinder, a five-axis air bearing carbide die grinder that uses the Bosch Rexroth IndraMotion MTX CNC controller and drive platform.

Tiny Bellows = Huge Performance! Miniature bellows from Servometer® are used as miniature pressure responsive devices, micro-seals, precision springs, electrical contacts or flexible micro couplings. These electrodeposited micro miniature metal bellows can be produced for a variety of stroke and pressure combinations and temperatures from -423° F to +350° F, with diameters as small as .020 inch (0.5 mm). Sample bellows available at no cost upon request. For additional information visit Servometer® online.
New high-resolution bolt is a smart fit
Seeing is believing, they say. Critical bolted joints often require exacting tightening procedures to establish the optimum clamp load. Direct Tension Indicator (DTI) SmartBolts were invented by Stress Indicators, Inc., to set up the proper bolt tension with no need for torque wrenches, strain gages, wires, or electronic or ultrasonic equipment. In fact, there is no need to touch or contact the fastener at all in order to verify its clamp load condition. A simple glance is sufficient. Read the full article
Dramatic increase in thermoelectric efficiency achieved
Researchers at Boston College and MIT have used nanotechnology to achieve a major increase in thermoelectric efficiency, a milestone that paves the way for a new generation of products — from semiconductors and air conditioners to car exhaust systems and solar power technology — that run cleaner. The team's low-cost approach involves building tiny alloy nanostructures that can serve as micro-coolers and power generators. Read the full article
Wheels: New 2- and 4-stroke prototype auto engine produces 27% fuel savings
Ricardo and a consortium of automotive partners recently completed an advanced prototype research program based on the highly innovative 2/4SIGHT engine concept. This gasoline engine concept uses novel combustion, boosting, control, and valve actuation technologies to enable automatic and seamless switching between two- and four-stroke operation, with the aim of delivering significant performance and fuel economy improvements through aggressive downsizing.

5-Star Product: Control computers half a mile away
Conventional cable-linked KVMs (keyboard, video, mouse devices) max out at about 500 ft, but the new CyberResearch wireless LVCW KVMs have an unobstructed range of 3,000 ft. Not only do they increase range by a factor of six compared to cable, they also slash costs by eliminating the hassles associated with laying cables. Simple antenna alignment is all you need.

Engineer's Toolbox: Whiplash gets one-two punch
Even a crash-test dummy needs a little help sometimes. If you're the physical BioRID II dummy, help comes in the form of new advanced finite element analysis (FEA) software that may — just may — take the blows for you once in a while. SIMULIA's Abaqus BioRID II (Biofidelic Rear Impact Dummy II) model, in combination with the physical BioRID II crash test dummy, is used by automotive OEMs and suppliers to evaluate the realistic performance of seats and head restraint systems.
