20090181870 | 1,3 DITHIOLANE-2-THIONE ADDITIVES FOR LUBRICANTS AND FUELS - Fuels, especially hydrocarbon fuels, and lubricants, especially lubricating oils, contain a class of anti-corrosion, anti-wear, anti-fatigue, and extreme pressure additives that are derived from 1,3-dithiolane-2-thiones. | 07-16-2009 |
20110306531 | ETHER POLYSULFIDES AND POLYETHER POLYSULFIDES, THEIR PREPARATION AND USE - Novel sulfur-containing compositions comprise a polyether polysulfide or an ether polysulfide. The polyether polysulfide may be based upon an alkoxylate (an alcohol or glycol-initiated compound) that is a copolymer of at least two of ethylene oxide, propylene oxide and butylene oxide. The polyether polysulfide may alternatively be based upon a homopolymer of ethylene oxide, propylene oxide or butylene oxide. The ether polysulfide may be based upon a methoxy-capped polyglycol or an alkyl ether of 1,3-dichloro-2-propanol. | 12-15-2011 |
20140038868 | SLIDING MEMBER - A sliding member includes: a substrate which has a sliding surface sliding under the presence of lubricating oil; and a film which is fixed to at least a part of the sliding surface. The film contains carbon (C), titanium (Ti), and boron (B), is obtained by repeatedly and alternately layering a first layer containing amorphous carbon as a principal component and a second layer containing C and Ti as principal components, and has hardness of 18 GPa or more. | 02-06-2014 |

20110118157 | RUST INHIBITORS TO MINIMIZE TURBO SLUDGE - A turbo-charged, sump-lubricated internal combustion engine which is susceptible to contamination of lubricant with liquid fuel, may be lubricated with a lubricant which contains an amount of a rust inhibitor effective to reduce the deterioration of said lubricant and turbo sludge formation. | 05-19-2011 |
20120302473 | OIL-IN-OIL COMPOSITIONS AND METHODS OF MAKING - This invention is directed to a lubricant composition that is comprised of a continuous phase and a discontinuous phase, i.e., a two phase lubricant composition. The continuous phase and the discontinuous phase of the lubricant of this invention are oil or oil type compositions that are essentially insoluble in one another. The lubricant composition is comprised of a continuous phase base oil that is comprised of a low viscosity Group II, III, IV or GTL base stock or a blend of at least two of the Group II, III, IV and GTL base stocks, optionally including a low viscosity Group V base stock, with the continuous phase base oil having, independently, a viscosity of from 1 to 100 cSt at 100° C. The lubricant composition is further comprised of a discontinuous phase that is comprised of an ester composition having a mean average droplet size of from 0.01 microns to 20 microns, in which the ester composition is comprised of an ester compound having no ether linkages. | 11-29-2012 |
20150080279 | Electrorheological Compositions - The present invention relates to an electrorheological composition with corrosion-inhibiting properties, methods for the production thereof and the use thereof. | 03-19-2015 |
