New double-coated adhesive tapes from Avery Dennison Specialty Tape Division could soon force unwanted bacteria to go swimming with the fishes. The tape incorporates a biocide to prevent bacterial and fungal growth in a variety of automotive, appliance, and electrical foam-bonding applications. Called FT 8395, the tape features a rubber-based formulation, and is available in two versions, one with 80# densified Kraft liner and the other with 12 point board line.
Gaskets don't have to be so darn creepy. Form-in-place gasket tape from W.L. Gore & Associates is made entirely from a PTFE that's been expanded in multiple directions for a reduction in creep relaxation and a retention of its thickness profile under compression. Called GORE-TEX BG, the tape comes in 1/8, 1/4, and 3/8 inch thicknesses and in widths of 1/4 to 6 inch. Applications include large-diameter or misaligned flanges as well as any other sealing applications that have to contend with surface irregularities or gaps. As it's made from PTFE, the tape resists a wide range of chemicals (pH 0-14), except for molten alkali metals. Operating temperatures range from -450 to 600F.
A line of three pressure sensitive tapes from Adhesives Research Inc. tackle a variety of mobile-phone assembly jobs. ARclad 8314 and ARclad 8901 are both 8-mil-thick, double-sided, acrylic bonding tapes—the former with a clear polyester carrier film and the latter with a black polyester carrier film. They address mounting and bonding tasks all over the phone—including nameplates, lens gaskets, loud speakers, and battery packs. A third double-sided acrylic tape, ARclad 7992, comes in an even thinner 5-mil thickness. All three tapes conform to curved surfaces.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
