Abstract:
This invention relates to a composition that is a novel improvement of non-oil containing metalworking fluids, also known as synthetic metalworking fluids. The invention is a non-oil containing metalworking lubricant composition, having an engineered particle size of greater than 200 nanometers upon dilution. The expansive particle size results in a substantial increase in lubricity, suitable for the heavy-duty operations previously attainable only with oil-containing products. Additionally, this non-oil containing metalworking lubricant incorporates the best of the positive attributes of oil-containing products into its composition, including excellent corrosion inhibition and heavy-duty operation capable lubricity.
Abstract:
The aim of the invention is to create a mixture for producing green bodies having high green strength and a high compression density, said mixture also helping to reduce the ejection force from the pressing tool. Said aim is achieved by a mixture comprising a metallic and/or plastic material and a pressing aid which contains 25 to 60 percent by weight of a polyglycol and 40 to 75 percent of a montan wax, the percentages being relative to the total quantity of the pressing aid.

Date Apr. 2, 1998The present invention relates to novel lubricant compositions comprising a solid lubricant and a binding agent in water medium suitable for lubricating steel-steel interfaces such as tractor-trailer couplings, rail-wheel systems and other heavy duty applications. The invention also relates to compositions described above which include friction modifiers with high or very high and positive coefficients of friction such that the coefficient of friction is considerably higher than the solid lubricant. The invention further relates to compositions comprising a binding agent and a friction modifier with a very high and positive coefficient of friction in a water medium.

Abstract:
A method of preparing thickened polyalphaolefin base oil greases comprises (a) producing a simple or complex soap thickener in a quantity of a first polyalphaolefin (PAO) of viscosity lower than that of the desired base oil component in the final grease composition to produce a thickened PAO and (b) adding to the thickened PAO a quantity of a second PAO of viscosity higher than that of the desired base oil component in the final grease composition sufficient to produce a final grease product having the desired base oil viscosity. Reduction in thickener quantity for given grade is achievable.
Abstract:
This invention provides oil-soluble complexes of oil-insoluble phosphorus-free strong mineral acids and alcohols. The complexes are useful antiwear additives in lubricating oils, particularly automatic transmission fluids.
