An improved process for preparing friction clutch facings comprising continuous fiber strand or filament wherein the continuous strand is extrusion-coated with an uncured or partially-cured friction resin composition, wound into a preform, then thermally cured under pressure.

Process for preparing friction clutch facing

Electrical conductors having an insulation layer comprising a thermosetting elastomeric composition capable of imbibing low molecular weight hydrocarbon well fluids when under pressure and rapidly desorbing the fluids when pressure is removed, and surrounded by a confining braid layer are able to withstand use in gassy oil wells without consequent depressurization-caused rupture failures. Armored electrical cables formed from these insulated conductors without an elastomeric jacketing are suitable for use in powering electric motors in oil wells that have particularly high proportions of gassy hydrocarbons under pressure without undergoing rupture failure.

Insulated and braid covered electrical conductor for use in gassy oil

Electrical cables having conductors, each provided with an insulation layer comprising a thermosetting elastomeric composition capable of imbibing low molecular weight well fluids when under pressure and rapidly desorbing the fluids when pressure is relieved which is surrounded by a confining braid layer, the insulated and braid-covered conductors being surrounded by a perforated outer armor formed of high temperature polyolefin, are able to withstand the environment within corrosive, gassy oil wells without corrosion of the armor and without undergoing depressurization-caused rupture failures.
