Abstract:
The bearing material produced by impregnating in the porous metal or alloy layers, for example, copper or copper-like alloy layers formed by known means, for instance by sintering on the back of a metal plate such as steel, a composition containing 1 to 30% by volume of one or both of a lead-tin alloy, which contains 1 to 25% by volume of lead fluoride and 3 to 30% by weight of tin, and lead wherein the total of the said lead fluoride and lead is 2 to 35% by volume and, as the residual part, polytetrafluoroethylene (PTFE). The capacity of the bearing may be further improved by adding about 0.1 to about 5% by weight of at least one member of the additives consisting of molybdenum disulfide, tungsten disulfide, cadmium oxide, aluminium oxide, calcium fluoride, lithium fluoride, graphite, lead iodide, glass fibre, carbon fibre and phosphates. The bearing is especially suitable for being applied to the shock absorber of vehicles moving under changeable load.

Abstract:
PURPOSE: To provide a parting agent for low-speed casting which does not pollute the working environment, has an excellent run property and lubricity, and has excellent washability of dies. CONSTITUTION: The parting agent for low-speed injection die casting consists essentially of an inorganic lubricant, spherical resin particles having an average particle size of 0.1 to 10 μm, organic carboxylic acid metal salt and water. The inorganic lubricant is 100 pts.wt., the spherical resin particles having the average particle size of 0.1 to 10 μm are 5 to 100 pts.wt., the organic carboxylic acid metal salt is 5 to 100 pts.wt. and the water is 100 to 1,000 pts.wt.
Abstract:
A lubricant additive for gear oils and an improved gear oil are disclosed. The additive comprises about 0.01 to about 65 percent, by weight, of solid lubricant particles selected from the group consisting of molybdenum disulfide, graphite, cerium fluoride, zinc oxide, tungsten disulfide, mica, boron nitrate, boron nitride, borax, silver sulfate, cadmium iodide, lead iodide, barium fluoride, tin sulfide, fluorinated carbon, PTFE, intercalated graphite, zinc phosphide, zinc phosphate, and mixtures thereof; combined with about 0.1 to about 25 percent, by weight, of a stabilizing agent consisting of an ethylene-propylene copolymer; and a fluid carrier. The lubricant additive provides the gear oil with improved demulsibility, stability, and compatibility characteristics of the gear oil when contaminated with water.
