Static electricity of polymers reduced by treatment with iodine

Treating organic polymers with iodine improves the electrical conductivity. Diffusion enables products of desired properties to be custom formulated. This eliminates a buildup of static electricity and the need for fillers or bound metal salts.

Lead plated aluminum ring provides static high pressure seal for large diameter pressure vessel

Lead plated aluminum ring provides a positive static seal for a large diameter pressure vessel for use in a hazardous environment at cryogenic temperatures with high pressure fluid flow. This design can be used in high and low pressure lines of any diameter for any fluid, with appropriate material modification.

Device measures static friction of magnetic tape

Device measures the coefficient of static friction of magnetic tape over a range of temperatures and relative humidities. It uses a strain gage to measure the force of friction between a reference surface and the tape drawn at a constant velocity of approximately 0.0001 inch per second relative to the reference surface.
