The present grease composition exhibits a long flaking life.

Abstract: The present invention provides a novel oligomeric olefin monoamine for use as an additive in fuel and related products and a method of producing the same. The oligomeric olefin monoamine is free of any undesirable halogens. The method of making the oligomeric olefin includes the steps of forming an oligomeric olefin epoxide, converting the epoxide to an alcohol and then converting the alcohol through the use of ammonia to an oligomeric olefin monoamine.

Abstract: A biodegradable scale inhibitor and dispersant is provided. The scale inhibitor includes a copolymer comprising at least one of N-oxygenatedhydrocarbonamide monomers and at least one of amino acid monomers. A method of reducing scale build-up on heating exchanger surfaces that come in contact with an industrial water is provided by adding a copolymer comprising at least one of N-oxygenatedhydrocarbonamide monomers and at least one of amino acid monomers to the water system such as cooling towers.

Abstract: A grease composition for constant velocity joints comprises (a) a base oil; (b) a lithium-containing thickener selected from the group consisting of lithium soap and lithium complex soap; (c) an organic molybdenum compound selected from the group consisting of molybdenum dithiophosphates and molybdenum dithiocarbamates; (d) a zinc dithiophosphate; (e) a sulfur-phosphorus extreme pressure agent free of any metal; and (f) a calcium salt selected from the group consisting of calcium salts of oxidized waxes, calcium salts of petroleum sulfonates and calcium salts of alkyl aromatic sulfonates. The grease composition for constant velocity joints exhibits a substantially improved effect of reducing friction coefficient and a substantially improved effect of reducing the axial force proportional to the third order component of rotation.

Abstract: A rust-removing composition comprises alkali metal hydrogen citrates, water, optionally citric acid, and optionally a thickener. The invention further provides a method for removing rust from rusted metal surfaces, concrete surfaces, and the siliceous surfaces of natural stone by applying the composition, allowing contact until substantially all of the rust is removed, and washing away the composition and dissolved rust with water.

Abstract: Compounds are described in which a polyamine moiety is linked to a phenolic moiety by a Mannich base linkage involving one of the amino groups of the polyamine moiety, and in which an aminoalkylene-poly(oxyalkylene) moiety is linked to the phenolic moiety by a Mannich base linkage involving an amino group of the alkylene-poly(oxyalkylene) moiety. Compounds of this type have been found to be highly effective in controlling the formation of intake valve deposits in internal combustion engines.

Abstract: The present invention improves the low temperature flow property of a fuel oil having a boiling point of 120.degree.-150.degree. C. by adding a novel compound prepared by reacting pri-, sec- or tert-aliphatic amine containing alkyl group of 1-30 carbon atoms with 9,10-dihydroanthracene-9,10-endo-.alpha.,.beta.-succinic acid or anhydride thereof together with a polymer having ethylene structure and/or a terpolymer of dialkyl fumarate-vinyl ester-vinyl ether.

Abstract: An aqueous lubricant for use in hot rolling of stainless steel to prevent roll scoring which comprises a viscous aqueous having dispersed therein from 1 to 30% by weight of iron oxide powder.

Abstract: Oil-soluble additives with dispersant properties inert towards fluoroelastomers are described, prepared by reacting an alkyl or alkenyl disuccinimide with an anhydride of an unsaturated bicarboxylic aliphatic acid or the corresponding acid. The reaction is conducted at a temperature of between 130.degree. and 170.degree. C. The molar ratio of anhydride to disuccinimide is between 1.05 and 1.

Abstract: A lubricating oil composition is herein disclosed which comprises as the main compounds, (A) a base oil comprising a mineral oil or a synthetic oil; (B) a hindered phenol compound represented by the general formula (I) or (II) ##STR1## wherein m is an integer of 1 to 5; (C) an alkylated diphenylamine compound; and (D) a borated succinic acid imide compound. This lubricating oil composition is excellent in heat resistance and oxidation stability in a gaseous phase of the oil, and it stably functions for a long time as a traction drive oil or the like.
