Stemming the Tide: The fluoro-elastomer
edge on teh SA33 gasket can withstand -40 10 150C fluids.
Many automotive gaskets may see coolant temperatures of "only" 110C (220F). But radiant heating, especially after shutdown, can drive temperatures at thermostats, exhaust-gas regenerator components, and water manifolds upwards to 150C.
To counter these conditions, engineers at InterFace Solutions Inc. have incorporated a fluoro-elastomer edge into the rubber-edged composite technology Select-a-Seal® system gaskets, SAS33 series. Unlike many such materials, this fluoro-elastomer is also formulated for low temperature performance, down to –40C. In addition, the edge resists erosion from high fluid-flow rates, allowing use in hydraulic pumps and motors.
The Select-a-Seal combines compressive and adhesive sealing. The adhesive action helps maintain the seal when the material relaxes over time, but can still be peeled off flanges. Compressible base material holding the seal also overcomes stress relaxation in the edge by transferring its stored energy to the seal to add to edge compression. Base material is chosen for shear resistance, strength, and temperature resistance, with a density and pore structure optimized to conform to flanges as well as irregularities in the finish. Material resilience can also be tailored to mitigate noise and vibration.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.

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.
