Abstract: A water washable thermally conductive grease useful for thermal coupling of electronic chips and heat sinks in electronic modules comprises a hydrophilic liquid polymer carrier, an antioxidant, and up to 90 weight percent of a microparticulate thermally conductive filler. In a preferred embodiment, the thixotropic dielectric composition further comprises an ionic surfactant to promote wetting/dispersion of the microparticulate filler. The thermally conductive grease is non-corrosive, resistant to shear induced phase destabilization and capable of being washed from module surfaces with aqueous solutions. Substitution of the present hydrophilic based greases for art-recognized solvent washable greases eliminates use of non-aqueous solvents in electronic module processing/reprocessing operations.

Abstract translation: 用于电子模块和电子模块中的散热器的热耦合的可水洗导热油脂包括亲水性液体聚合物载体，抗氧化剂和至多90重量％的微粒状导热填料。 在优选的实施方案中，触变介电组合物还包含离子表面活性剂以促进微粒填料的润湿/分散。 导热油脂是无腐蚀性的，耐剪切诱导相不稳定，并能够用水溶液从模块表面洗涤。 用于本领域公认的溶剂可洗涤润滑脂的本亲水基润滑脂的替代消除了在电子模块处理/再处理操作中使用非水溶剂。

Abstract: A solid lubricating material consisting essentially of an intimate mixture of about 15 to 50 mole percent molybdenum trioxide, balance molybdenum disulfide. This material is particularly useful under extreme environmental conditions such as very high temperature or vacuum. The material may be used in powder form, compacted into a pellet or other desired shape, incorporated into a grease composition or incorporated into a resin-bonded solid film lubricant.

Abstract: A LUBRICANT CONCENTRATE COMPOSITION WHICH COMPRISES FROM ABOUT 3 TO 75 PERCENT BY WEIGHT OF AN ALKALI METAL ORTHOPHOSPHATE, ABOUT 15 TO 97 PERCENT BY WEIGHT OF AN ALKALI METAL FATTY ACID SOAP, CONTAINING FROM ABOUT 8 TO 22 CARBON ATOMS, AND AT LEAST 0.1 PERCENT BY WEIGHT OF A SURFACE ACTIVE AGENT SELECTED FROM THE GROUP CONSISTING OF NON-IONIC ETHYLENE OXIDE-ALCOHOL CONDENSATES AND AMPHOTERIC BIODEGRADABLE SURFACE ACTIVE AGENTS. ADDITIONALLY, THE CONCENTRATE COMPOSITION MAY CONTAIN FROM ABOUT 0.1 TO 80 PERCENT BY WEIGHT OF A WATER DISPERSIBLE DILUENT SELECTED FROM WATER SOLUBLE AND COLLOIDALLY SUSPENDABLE DILUENTS, SUCH AS SUGAR AND POLYETHYLENE GLYCOL HAVING A MOLECULAR WEIGHT FROM ABOUT 100 TO 10,000. AN AQUEOUS LUBRICANT COMPOSITION CONTAINING FROM ABOUT 10 TO 400 POUNDS OF THIS CONCENTRATE PER HUNDRED GALLONS OF SOLUTION MAY BE USED TO FORM A LUBRICANT COATING ON A CHEMICALLY COATED METAL SURFACE, SUCH AS A PHOSPHATE COATED METAL SURFACE, WHICH SURFACE MAY THEN BE DEFORMED AFTER THE LUBRICANT COATING HAS BEEN DRIED.

Abstract: Systems and methods are provided for block operation during lubricant and/or fuels production from deasphalted oil. During “block” operation, a deasphalted oil and/or the hydroprocessed effluent from an initial processing stage can be split into a plurality of fractions. The fractions can correspond, for example, to feed fractions suitable for forming a light neutral fraction, a heavy neutral fraction, and a bright stock fraction, or the plurality of fractions can correspond to any other convenient split into separate fractions. The plurality of separate fractions can then be processed separately in the process train (or in the sweet portion of the process train) for forming fuels and/or lubricant base stocks. The separate processing can allow for selection of conditions for forming lubricant fractions, such as bright stock fractions, that have a cloud point that is lower than the pour point.

Abstract: The present invention relates to an engine oil lubricant composition for use in internal combustion engines comprising one or more molybdenum containing compounds that deliver 1-1000 ppm molybdenum to the finished oil, one or more phosphorus containing compounds that deliver 25-650 ppm phosphorus to the finished oil, and one or more poly(meth)acrylate viscosity index improvers (VI improvers) that may or may not be functionalized, for improved fuel economy and turbocharger related deposits. In addition, the composition comprises an antioxidant system which is carefully balanced to provide improved fuel economy, comprising an aminic antioxidant, a phenolic antioxidant and an ashless dithiocarbamate. Additionally, the formulated oil may contain a dispersant poly(meth)acrylate, in addition to the PAMA VI improver, to reduce the amount of traditional succinimide dispersants.
