Abstract: An insulative cover is utilized to protect an insulator supporting an electrical power line relative to a support structure in an electrical power transmission system. A first end of the cover is secured to the insulator adjacent the insulator's first end and a second end of the cover is secured to the insulator adjacent to the insulator's second end. The cover defines a volume substantially enclosing a central portion of the insulator.

Abstract: The present invention is directed to a low friction coating composition, comprising (1) about 60 wt% to about 95 wt % of a high temperature epoxy; (2) about 1 wt % to about 30 wt % of molybdenum disulfide; and (3) about 1 wt % to about 20 wt % of polyimide powder, all based on the total weight of the coating composition. The present invention is also directed to a substrate coated with the low friction coating composition of the invention, and a method of coating a substrate with the low-friction coating composition of the invention.

Abstract: A self-lubricating coating composition that is a curable admixture of two specific epoxy resin compositions; a di-epoxide reactive diluent; polytetrafluoroethylene; molybdenum disulfide, and mica. This composition, when cured, may be incorporated onto the undamaged surfaces or into damaged or worn areas of a substrate (e.g., aircraft fuel and oil pump housings).

Abstract: A bearing assembly comprises coengaging inner race and outer race members movable relative to one another. The inner race has an outer bearing surface to which is fixedly secured a self-lubricating bearing material which engages and is movable relative to the bearing surface of the outer race member. The outer race is case hardened titanium.

Abstract: A track-roller bearing assembly is disclosed which includes a fixed inner ball race member having an outwardly facing arcuate peripheral bearing surface; an annular body of self-lubricating bearing material affixed to the outwardly bearing surface of said inner race; and a coaxial outer race which is rotatable about an axis of the inner race and anguarly displaceable relative to the axis of the inner race so as to accommodate track deflections or irregularities. The track-roller further includes a resilient element disposed between respective ends of the inner and outer races so as to bias the races back into axial alignment after they have been angularly displaced relative to each other.

Abstract: A flanged bearing includes a layer of woven braid which is continuous throughout a sleeve and a flange portions thereof, with at least one braid strand substantially parallel to a bearing axis. The sleeve may be cylindrical in shape and the flange portion washer shaped, and the braid may include carbon fiber strands impregnated with a polyimide resin so that the bushing is lightweight and self-lubricating at high temperatures.

Abstract: A light-weight push, pull and/or torsion rod includes a light-weight core, fittings on either end, pins protruding from the outer surface of each fitting, and a tubular strength member surrounding the core and overlapping much of the end fitting. The strength member includes a fibrous braided layer which overlaps and closely captures the protruding tips of the pins to anchor the strength member to the end fitting. In one embodiment, the end fittings are conically tapered from the side adjacent the core and flare out from the narrow end of the cone, and the braid is woven tightly around the conical portion and flared portion of each end fitting so that the strength member abuts or bears against the end fitting when the rod is exposed to tension or compression forces.

Abstract: A bearing assembly comprises two engaging members movable relative to one another. One of said members has a bearing surface made of metal or ceramic coated with a thin film of a parting agent, and the other bearing surface is a woven fabric impregnated with a cured acrylate composition.

Abstract: The disclosure embraces a self-aligning spherical bearing having two hemispherical rings; each of the rings have inner annular surfaces and substantially planar mating surfaces; one of the mating surfaces is provided with a recess adjacent its inner arcuate edge while the other mating surface is provided with a projecting lip on its inner arcuate edge so that, when the mating surfaces are disposed in abutting relationship, the recess and lip will define a circumferential cavity; a ball member is disposed between the ring members prior to placing the mating surfaces in abutting relationship and then the mating surfaces are fusion-bonded by an energized beam of electrons to form the assembled spherical bearing.

Abstract: The disclosure embraces a method of securing sealing members in place in a bearing of the type having two relatively movable members, one being an outer bearing member having a surface that is complementary to the exterior surface of the inner bearing member; the method includes the steps of disposing the inner member inside of the outer bearing member, with the sealing members located between opposing surfaces of the inner and outer bearing members so as to maintain a space between the surfaces of the bearing members, injecting a curable mixture of a bearing surface compound in the space between the bearing members, curing the injected compound to form a bearing surface on the inner surface of the outer bearing member and to bond the sealing members in place; the disclosure also embraces a bearing member made according to the foregoing method.

Abstract: A bearing assembly comprises two engaging members movable relative to one another. One of said members has a bearing surface made of metal or ceramic coated with a thin film of a parting agent, and the other bearing surface is a cured mixture of a curable acrylate composition and particulate polytetrafluoroethylene.
