Abstract: Diesel engine cylinder oils of improved cleanliness and load carrying ability and reduced port deposit characteristics for use in marine and stationary slow speed diesel engines are based on medium heavy Group I or Group II neutral base oils, typically from 300 to 500 SUS using a liquid, oil-miscible polyisobutylene (PIB) in combination with the neutral base stock and an additive package comprising a detergent component or components, an antioxidant, an antiwear agent, and a dispersant. The detergent component preferably comprises one or more overbased phenates, phenylates, salicylates or sulfonates in order to confer the desired alkalinity characteristics on the finished oil. The oils are produced in the viscosity range of 15 to 25 cS (100° C.), usually with a nominal viscosity of 20 or 24 cS, i.e., from 18.5 to 21.9 cS or 21.9 to 26.1 cS (100° C.). The viscosity index of the improved oils is at least 95, typically from 105 to 120. Total Base Number of the oils is in the range 40 to 100.
Abstract: A lubricating oil composition has a major amount of an oil of lubricating viscosity, a minor amount of a carbonated sulfurized metal alkyl phenate and, a minor amount of a carbonated metal alkyl aryl sulfonate. The total base equivalents donated by the phenate is more than 85% of the total base equivalents donated by the phenate and sulfonate. The composition also has alkenyl or alkyl succinimide additives that are the reaction product of a high molecular weight alkenyl- or alkyl-substituted succinic anhydride and a polyalkylene polyamine having an average of greater than four nitrogen atoms per mole, wherein the reaction product is post-treated with a cyclic carbonate.

Abstract: An improved micro machine has at least a first element which is moveable relative to a second element such that the first and second elements can be in contact with each other. The contacting portions of both the first and second elements are protected with a long-lasting lubricant to prevent the elements from sticking or adhering to each other. The lubricant is a polar low molecular weight compound preferably applied as a vapor. This class of low molecular weight lubricants consists of acetone, ethanol, ethylene glycol, glycerol, isopropanol, methanol, and water. According to the disclosure a lubricant has a low molecular weight if its molecular weight is less than ˜100 amu, or has a vapor pressure ≧5 Torr at room temperature. The preferred micro machine is a GLV wherein the bottom of the deformable ribbon contacts the landing electrode when the reflector is in a down position (close to the substrate).
Abstract: The invention provides dispersants and dispersant viscosity index improvers which include polymers of conjugated dienes which have been hydrogenated, functionalized, optionally modified, and post treated. The dispersant substances include a copolymer of two different conjugated dienes and an aryl-substituted olefin. The polymers are selectively hydrogenated to produce polymers which have highly controlled amounts of unsaturation, permitting highly selective functionalization. Also provided are lubricant fluids, such as mineral and synthetic oils, which have been modified in their dispersancy and/or viscometric properties by means of the dispersant substances of the invention. Also provided are methods of modifying the dispersancy and/or viscometric properties of lubricating fluids such as mineral and synthetic lubricating oils. The dispersant substances may also include a carrier fluid to provide dispersant concentrates.
