Abstract:
An engine lubricant formulated as a complete crankcase motor oil or additive concentrate composed of a combination of chemical constituents including a base oil selected from a synthetic oil, a mineral oil or semi-synthetic base oil (hydrogenated oil) or combination thereof, an oil soluble molybdenum additive, a dispersant inhibitor containing zinc dithiophosphate, and viscosity index improvers and one or more seal swelling agents to lubricate the engine and recondition the seals of new and/or high mileage engines. Addition of a polyalphaolefin and/or one or more esters such as a diester or polyolester may also be utilized therein. The lubricant may be formulated as a complete engine oil crankcase lubricant, or concentrated into an additive for addition to conventional mineral oil based engine oil, synthetic engine oils, or blends thereof in an effective amount of up to 30 percent volume percent, typically from 20 to 25 percent by volume.

NOVEL COMPOSITIONS OF MATTER FORMED OF AMMONIA, HYDRAZINE, AND ORGANIC NITROGEN COMPOUND INTERCALATES AND HEAVY METAL LAYERED CHALCOGENIDES, WHEREIN THE CHALCOGEN IS SELECTED FROM SULFUR, SELENIUM AND/OR TELLURIUM. THE NOVEL INTERCALATED COMPOUNDS DISPLAY ADVANTAGEOUS CARACTERISTICS WHEN UTILIZED AS SOLID LUBRICANTS, AND AS DIFFRACTION GRATING CRYSTALS. CERTAIN OF THE INTERCALATED TRANSITION METAL CHALCOGENIDES ALSO EXHIBIT UNIQUE SUPERCONDUCTIVITY CHARACTERISTICS.
Abstract:
A swash plate type compressor is arranged with a plurality of semispherical shoes 4 and a disc shaped swash plate 2. A resin coating 12 is formed on a surface 2A and a rear surface 2B (sliding surface) of the swash plate 2 which slides with the shoe 4. The resin coating 12 includes a structure whereby multiple hexagonal cylinder bodies 12B are fabricated on a surface of a substrate 11 and an end surface 12C of each cylinder body 12B forms a sliding surface which slides with the shoe 4. In addition, a honeycomb shaped groove 12A is formed at an adjacent position of each cylinder body 12B forming a storage part of a lubricant O and a container part for foreign objects 15. The swash plate 2 can be provided with excellent wear resistance, seizure resistance and lubrication retention.
Abstract:
A lubricating composition for cold working which has good lubricating and anti-seizure properties and which is less flammable without addition of a chlorine compound and a method for cold working using the same are provided. The lubricating composition for cold working comprises at least one carbonate selected from alkali metal carbonates and alkaline earth metal carbonates and at least one hydroxide selected from alkali metal hydroxides and alkaline earth metal hydroxides in a lubricating base oil and which is free of chlorine compounds, wherein the content of the carbonate in the composition is at least 10% by mass and less than 100% by mass and wherein the content of the hydroxide is greater than 0 parts by mass and at most 5 parts by mass per 100 parts by mass of the carbonate.
Abstract:
This invention is directed to a liquid metal and oil treating composition and to the process of preparing the composition. In the process there are first mixed together a vegetable oil such as cashew oil, anoleate ester such as magnesium oleate, and Ingredient A which is material selected from the group consisting of (a) ferric chloride, (b) at least one of pulverized lead oxide, ferric oxide, iron carbide, chromium carbide and tungsten carbide dispersed in an aqueous solution of acid selected from the group consisting of hydrochloric acid, perchloric acid and sulfuric acid. The acid solution is concentrated, preferably containing about 40 volume % acid. The mixture is heated and stirred and then distilled. The residue is then heated to about 100-150°F, while adding to it, with stirring, an antioxidant, a polar hydrocarbon, a carbonyl, a carboxyl amide, a viscosity improver, at least one of a tackifier and a sulfonate, and a petroleum oil until a homogeneous liquid is obtained.
Abstract:
The invention relates to lamina-like iron pigments produced by the deformation of carbonyl iron powder, the lamina-like iron pigments having a size distribution of a D- 50 value in a range of 3 to 16 μm and a size-to-thickness ratio in a range of 2 to 50. The invention further relates to a magnetorheological fluid containing the lamina-like iron pigments according to the invention, and to a device containing the magnetorheological fluid.
Abstract:
A motor oil performance-enhancing engine treatment oil additive formulated for addition to conventional motor oil to improve the lubricating properties of the engine oil and enhance the performance of the engine. The novel engine additive comprises a synergistic combination of chemical constituents including an oil soluble molybdenum additive, polyalphaolefin, diester, polytetrafluoroethylene, dispersant inhibitor containing zinc dithiophosphate, mineral oil base stock, viscosity index improvers, and borate ester used in combination with a conventional crankcase lubricant at about a 20 to about a 25% volume/percent. The improved performance of the engine additive in comparison with conventional crankcase lubricants is attributable to the synergistic effect of optimizing the design parameters for each of the individual chemical constituents and combining the chemical constituents according to the present invention to obtain surprisingly good results including improved: wear, oxidation resistance, viscosity stability, engine cleanliness, fuel economy, cold starting, and inhibition of acid formation. The novel engine additive formulation comprises a synergistic combination of compounds, ingredients, or components, each of which alone is insufficient to give the desired properties, but when used in concert give outstanding lubricating properties. Of course, it is contemplated that additional components may be added to the engine additive formulation to enhance specific properties for special applications.
