Engineers say seals made with Parker Hannifin's carboxylated HNBR sealing material operate better in extremely high temperatures and with highly abrasive fluids than other nitriles. A Canadian oil-well tooling company is using the material as the packing element around casing and piping in oil wells. The well fluids are corrosive and eat the casings, experts say. Plus, the farther into the well hole the tools go, the higher the temperatures they meet. The holes can go down to 10,000 ft. The XHBNR works in temperatures up to 300F and has a tensile strength of 5000 psi. It also resists hydrogen sulfide.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicleís parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but thatís just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
