Greases for homokinetic joints incorporating an organic molybdenum compound

Improved greases for use in homokinetic joints are proposed which comprise a base oil, a thickening agent, and an organic molybdenum compound. Greases comprising a base oil, a thickening agent, an organic molybdenum compound, and an organic zinc compound are also proposed. These greases exhibit smaller friction coefficients than conventional greases used for this purpose. On the homokinetic joint lubricated with the grease according to the present invention, the axial force produced is reduced and vibrations generated on the engine are absorbed. The vehicle is prevented from vibrating. The use of an expensive organic metallic extreme-pressure additive is unnecessary.

Improvements in or relating to ribbons of foils, films or the like containing cellulose derivatives and to wires and other articles covered therewith

Talc or like solid unctuous substance is applied to ribbons of foil made of or containing cellulose derivatives, and the ribbons are then wrapped on electric conductors such as wires, cables, ribbons, bus-bars, and coils. The solid lubricant does not impart tackiness as is the case with oils, and it enables narrow ribbons of foil to be passed at high speed through the guides of the winding devices, and to be unwound from packages without sticking. Instead of talc, there may be used a metallic salt of a fatty acid such as zinc stearate or palmitate, or aluminium oleate, or bismuth oxychloride, or fuller's earth. The solid lubricant may be applied by rubbing, dusting, or blowing on to the surface of the foil. The quantity deposited is preferably so small that the transparency is not materially affected and subsequent cementing or welding is not interfered with. The foil may be of cellulose nitrate, acetate, formate, propionate, or butyrate, or of methyl, ethyl, or benzyl cellulose. The foil ...

Substantially linear ethylene/alpha-olefin polymers as viscosity index improvers or gelling agents

Substantially linear ethylene polymers, such as ethylene/octene copolymers and ethylene/propylene/diene modified polymers, when added in a viscosity modifying amount to an oleaginous material, such as a lubricating oil, provides the material with a viscosity index that exceeds that of the material alone. The substantially linear ethylene polymers, prepared by constrained geometry catalysis, may be grafted with one or more unsaturated organic compounds, such as maleic anhydride, that contain ethylenic unsaturation. The grafted polymer may be further functionalized by reactions with, for example, an alcohol or an amine compound. The substantially linear ethylene polymers, when subjected to shearing action either before or after addition to an oleaginous material, improve shear stability of the oleaginous material. The substantially li near ethylene polymers, whether grafted, grafted and further reacted or not, also work as a thickening agent for compositions such as those used in greases, cable filling coumpounds and cosmetics. In addition, the substantially linear ethylene polymers provide effective results when blended with other components of conventional oleaginous material compositions.
