A retreading envelope is produced by extruding an elastomeric material in substantially tubular form, with portions of the wall thickness of the circumference of the extruded tubing being of a thickness substantially greater than the wall thickness of the remainder of the tubing, cutting a length of the extruded tubing from the tubing as extruded, and butt-seaming the free ends of the cut length t...

A colored resin composition characterized in that it has a matrix of a thermoplastic polymer (A), typically a polyester, and a thermoplastic polymer (B), typically a styrene polymer, which is dispersed in the matrix and is separated in phase from the matrix, and the polymer (B) is filled with substantially the entire quantity of a colorant. Since the colorant is blended in only the dispersed phase...

A stable latex composition possessing a viscosity of less than about 50 cp. comprised of an ethylacrylate/methylacrylic acid/acrylic acid polymer and co-surfactant system comprising a nonylphenol polyethylene oxide ether sulfate and a propoxylated, ethoxylated propylene glycol nonionic surfactant block polymer useful for increasing the viscosity of water that is injected into subterranean petroleu...

A disc brake for a vehicle has a pair of friction pads which are disposed on each side of a disc. A shielding plate is provided in such a manner as to shield a boot which shields at least one slide portion. Thus, the boot is protected from sparks which are generated by contact between the disc and the pads, and the boot is thereby prevented from being burned and deteriorated.

A guide for supporting a moving handrail or an escalator or moving walk is formed from a sheet of rolled spring steel or the like. The guide fits onto the top edge of a glass balustrade on the escalator or walk. The guide is secured to the glass balustrade solely by means of a spring clamping action which results from stressing the guide when it is forced down over the glass. The guide is formed w...
