The choice of a refrigeration motor is much bigger than a hum, a whir, or a whine. Electronically communicated motors are beginning to challenge shaded pole and PSC motors, but issues with reliability and motor surge currents, some real, some perceived, may be holding ECMs back.
Advancements in polymers in recent years are expanding the capacities of cooking appliances. Lightweight, tough plastics are catching up to the dishwasher durability and surface integrity of glass, but are consumers ready to pay more for it?
Cornell Dubilier is a leading manufacturer of capacitors for the power electronics market. For the past several years, the company has used ultrasonic spot welders to weld multiple layers of foil to capacitor posts.
Vibration welding uses heat generated by friction at the interface of two thermoplastic parts to produce melting in the interfacial area. The molten materials flow together under pressure and bond, forming a weld upon cooling.
This past year, baby boomers began turning 65. Because these individuals tend to live more active lives than previous generations, some medical device companies, like Skeletal Dynamics, are developing implants to withstand up to 1 million load cycles without loosening or backing out.
Engineers have developed several ways to detect extension or retraction of a pneumatic cylinder. Anisotropic magnetoresistive and giant magnetoresistive sensors are smaller, faster and reliable alternatives.
Wireless technology has created a new class of devices that easily move about the plant floor. Mobile powered workstations improve efficiency, eliminate waste and boost productivity.
Orion RED has fabricated several sets for the Academy Awards. For the 2011 ceremony, the company was asked to create an elegant, crystal-studded “Winners Circle” in which the honorees would receive their Oscars. The project involved building a 15.5-foot circular stage studded with more than 40,000 Swarovski Elements crystals.
Canadian manufacturers such as Plastech Inc. have high natural gas bills, especially in the winter. Over time, Plastech’s natural gas bill has increased to $6,000 annually (Canadian) just to heat its shipping area. So the company began looking into solar technology to lower its heating costs and learned about Lubi solar air heaters.
