The mold release properties of a molded polyurethane foam are improved by including the foamable mixture to be molded, a reaction product of a polysiloxane and an organic monoisocyanate or polyisocyanate.

A power line disturbance (PLD) detector circuit includes a digital counter which is driven by pulses provided by a clock in an associated data processing system. The PLD detector circuit includes a comparator amplifier for comparing primary AC power to a DC reference voltage on a cycle-by-cycle basis. The amplifier generates a reset pulse once during each AC cycle as long as the AC voltage exceeds...

A process is provided for mechanically surface-finishing a textile fabric which comprises ccontinuously feeding said fabric from a source of supply, such that said fabric lies in a single plane, subjecting successive adjacent sections of the fabric to intermittent mechanical impact with an abrasive means across the width of said fabric thereby avoiding substantial sustained contact between the fab...

PURPOSE:To produce the titled resin having high fluidity and low scattering tendency, by adding and mixing a specific organic liquid to an aqueous dispersion of vinyl chloride resin, separating the obtained granular aggregate from the water phase, and drying the aggregate while restricting the content of the fine particles in the separated aggregate. CONSTITUTION:A 10-70wt% aqueous dispersion of a...

A disc brake for installation on heavy automotive vehicles, comprises at least two rotating discs fixed to each other and spaced apart axially and rigidly fixed on the brake rotor, and a stirrup fixed on the brake stator. The stirrup comprises two external portions between which the discs are disposed, and at least one intermediate portion between the discs. The stirrup portions have pairs of oppo...

PURPOSE:A hollow superconductive wire is obtained by securing the molded units comprising braiding and molding composite strand wires then heat treating these to form superconductive intermetallic compound to the grooves on the outside diameter of ahollow conductor.

A brake actuator for a vehicle having air brakes is disclosed in which air pressure is expelled through the actuator upon release of the brakes in order to purge the latter of contaminants. The actuator includes a housing in which a piston reciprocates. Fluid pressure is admitted to the chamber defined between one side of the piston and the corresponding end of the housing in order to urge the l...

A sealing ring firmly grips a movable piston, performs the normal sealing function, and when pressure is released on the piston the sealing ring pulls back on the piston so as to retract the piston. The sealing ring is designed so as to fit in a conventional seal or "O" ring groove without any modification of the groove.

Starch products which were hitherto used as pore-forming substances in the manufacture of polyvinyl alcohol acetal sponges are replaced by polyethylene glycol or polyacrylamide. This results in a more uniform distribution of pore size, lower shrinkage of the sponge material during the acetalization, and easier washing of the sponge after the acetalization.

Thermoplastic polystyrene laminates are disclosed, one of the layers of which comprises a filled polystyrene composition containing from about 5 to about 50 of filler, such as calcium carbonate, clay, asbestos, etc. The filled polystyrene composition is prepared from a filled polystyrene masterbatch of impact polystyrene, filler, rubber and mineral oil, cut back by mixing with other polystyrene, e...
