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.
Abstract:
The coefficient of friction of aluminum can surfaces after alkaline cleaning and drying can be substantially reduced by adding to the alkaline cleaner a mobility enhancing additive, preferably a surface active quaternary ammonium salt with hydroxyethyl substituents on the quaternary nitrogen atoms. A can surface suitable for automatic conveying and high quality lacquer or printing ink adhesion can thereby be obtained, if desired without including any substantial fluoride content in any treatment stage.
Abstract:
Railroad wheel flange lubricating is carried out with a lubricating composition which is particularly useful in a locomotive-mounted applicator. The water base lubricant comprises a compatible blend of two polyoxyalkylene glycols, one a synthetic lubricant and the other a synthetic thickener. The lubricating composition is persistent and environmentally innocuous.
Abstract:
The present invention concerns a surface coating sliding member made of rubber or plastic applied with a coating of excellent durability and high sliding property, in which the coating contains a solid lubricant such as molybdenum disulfide and a resin matrix, wherein the resin matrix comprises a fluoro-olefin vinyl ether polymer resin and/or fluoro-olefin vinyl ether vinyl ester copolymer.
Abstract:
An electrorheological material comprising a carrier fluid and an atomically polarizable particle component. The atomically polarizable particle component has a crystalline lattice structure which allows atoms to shift position with respect to each other in response to the application of an electric field. The electrorheological materials are subjected to an alternating current electric field at a frequency of at least 500 Hz. The materials exhibit substantial electrorheological activity over a broad temperature range.
Abstract:
A composition useful as a rinse aid for metal surfaces and for improving the mobility of formed metal surfaces is described. The composition comprises(A) from about 10 to about 90% by weight of at least one nonionic polyoxyalkylene glycol comprising poly(oxypropylene) hydrophobic groups and poly(oxyethylene) hydrophilic groups, and(B) from about 10 to about 90% by weight of at least one alkoxy derivative of at least one ethoxylated and propoxylated glycol, and particularly at least one nonionic polyoxyalkylene glycol comprising poly(oxypropylene) hydrophobic groups and poly(oxyethylene) hydrophilic groups. A process is also described for improving the drainage of water from metal surfaces and for improving the mobility of formed metal surfaces. The process comprises contacting said metal surface with an aqueous composition comprising water and the above-described composition. The composition and process of the present invention result in lower oven temperatures and reduced coefficient of friction which results in improved mobility.
Abstract:
A high performance lubricating grease effectively lubricates and greases front-wheel drive joints. The lubricating grease has excellent extreme pressure properties and antiwear qualities and is economical, effective, and safe. In one preferred form, the lubricating grease comprises a base oil, a polyurea thickener, an additive package comprising calcium sulfate and calcium acetate.
Abstract:
An aqueous hydraulic fluid comprising as, active ingredients, 5-30% by weight of alkylpolyglycoside, 0-20% by weight of surfactant additives, and 0-10% by weight of nonsurfactant additives; and water to 100% by weight; the proportion of active ingredients in the fluid being at most 40% by weight; provides a medium for energy transfer having adequate viscosity and good lubricating action at low concentrations of active ingredients.
Abstract:
Marked mineral oils containing basic dyes which have at least two, optionally substituted, amino groups and which, on addition of a protogenic acid and, optionally, a metal halide, experience a bathochromic shift of their absorption maximum and an increase in absorbance, and a method of marking mineral oils with basic dyes.
