Abstract: Suspensions comprising an organic base and at least one carrier fluid. The organic base comprises an amine group and at least one hydrophobic group attached to the amine group. The at least one hydrophobic group may be functionalized with one or more functional groups. Methods of extracting and obtaining a hydrocarbon material from a subterranean formation or bitumen using the suspension are disclosed.

Abstract: A fuel soluble additive for a diesel engine, a method for improving performance of fuel injectors and a method for cleaning fuel injectors for a diesel engine. The fuel soluble additive includes a quaternary ammonium salt derived from the reaction of (a) a hydrocarbyl amine containing at least one tertiary amino group, (b) an epoxide compound selected from a glycidol, a glycidyl ether, glycidyl ester, polyglycidyl ether, a polyglycidyl ester, and combinations thereof, wherein substituents of the glycidyl group have, on average, less than five carbon atoms per hetero atom, and (c) optionally a proton donor.

Abstract: The invention provides a lubricating composition containing an oil of lubricating viscosity and a nitrile compound. The invention further relates to a method of the lubricating an internal combustion engine with the lubricating composition.

Abstract: Disclosed are a lubricant composition to which is added as buffer particles to a lubricant polyurethane resin particles obtained by reacting and synthesizing long-chain polyol having a number-average molecular weight of not less than 500, a crosslinking agent having three or more active hydrogen groups in one molecule, and polyisocyanate as buffer particles, a speed reduction gear filled with the lubricant composition, and an electric power steering apparatus having the speed reduction gear incorporated therein, wherein noise produced by the speed reduction gear can be made lower than ever before irrespective of the magnitude of backlash in a case where a worm and a worm wheel are combined with each other and without complicating the configuration of the speed reduction gear by the buffer action of the buffer particles added to the lubricant composition, thereby making it possible to reduce noise produced in an automobile due to the electric power steering apparatus at low cost.

Abstract: The present invention provides a rolling apparatus comprising a movable member which can undergo rotary or linear motion, a support member which carries the movable member, rolling elements which are interposed between the movable member and the support member and which roll with the movement of the movable member, and a lubricant composition which is disposed between the movable member on which the rolling elements roll and the support member, wherein the lubricant composition is a mixture of (1) a thickening agent which is at least one selected from the group consisting of a solid fluoropolymer, a lamellar mineral powder, an ultrafinely particulate organic material, an organic solid lubricant and an ultrafinely particulate inorganic material, and (2) a base oil comprising a liquid fluorinated polymer oil.

Abstract: The present invention relates to at least simply unsaturated polyolefins with a number mean molecular weight in the range of 400 to 1,500 dalton and a dispersibility of M.sub.W /M.sub.N <1.2, obtained through catalytic dimerization from at least simply unsaturated olefin-oligomers, as well as to the method for their production. The present invention further relates to derivatives of these polyolefins which can be obtained by functionalizing at least a double link of the polyolefin. The invention also relates to the use of polyolefins and/or functionalization products as additives for fuels or lubricants.

Abstract: The lubricant of this invention is a combination of a PLURONIC.RTM. polyol and a phospholipid. The lubricant is applied to the surface to be lubricated by forming a solution of water and the lubricant. This solution may also include Vitamin E or its derivative. In addition, a solution stabilizer and an antimicrobial agent may be used to clarify the solution and to inhibit microbial growth in the solution.

Abstract: Lubricants containing a compound of the structureR.sub.1 R.sub.2 N--C(X')S--(CR.sub.3 R.sub.4).sub.a Ywhere X' is an oxygen or sulfur atom and Y is, e.g., an activating group; also containing a phosphorus acid or ester of the formula (R.sub.6 X)(R.sub.7 X)P(X).sub.n X.sub.m R.sub.8 or an amine salt thereof; and also a surfactant, exhibit good antiwear properties. They are particularly useful in pressure transmitting applications such as tractor hydraulic fluids.

Abstract: Oil soluble compounds having the formula: ##STR1## wherein R and R.sup.1 are independently cyano, alkoxycarbonyl, aryloxycarbonyl, alkenyloxycarbonyl, alkylcarbonyl, arylcarbonyl, alkenylcarbonyl, alkylsulfonyl, arylsulfonyl, alkenylsulfonyl, substituted aminocarbonyl, alkylphosphoryl, arylphosphoryl, alkenylphosphoryl, aryl, or heterocyclics, or together form a carbocycle or heterocycle, and R.sup.2 and R.sup.3 are independently alkyl, alkenyl, hydroxyalkyl, sulfurized alkyl, alkoxycarbonylalkyl, arylalkyl, or borated hydroxyalkyl, with the proviso that R, R.sup.1, R.sup.2 and R.sup.3 together contain sufficient carbon atoms to render the compound oil soluble in an oil of lubricating viscosity. The compound are useful as wear protectants or extreme pressure agents to enhance wear protection or extreme pressure properties in lubricating oils and greases.
