Patent number: 6660695Abstract: A power transmission fluid comprising a mixture of a major amount of a lubricating oil and an effective amount of a performance enhancing additive combination comprising: (a) at least one organic phosphate having the structure R1—X2—P(:X1)(R2X3)—X—R5 where R1, and R2 may independently be substituted or unsubstituted alkyl, aryl, alkylaryl or cycloalkyl having 1 to 24 carbon atoms and X, X1, X2 and X3 may independently be sulfur or oxygen. R1 and R2 may also contain substituent hetero atoms, in addition to carbon and hydrogen, such as chlorine, sulfur, oxygen or nitrogen; wherein R5 is derived from a reactive olefin and can be either CH2—CHR—C(:O)O—R6; —CH2—CR7HR8; or R9—OC(:O)CH2—CH—C(:O)O—R10 where R is H or the same as R1, R6, R7, R9 and R10 are the same as R1 and R8 is a phenyl or alkyl or alkenyl substituted phenyl moiety, the moiety having from 6 to 30 carbon atoms, (b) a calcium detergent, and (c) a friction modifier.Type: GrantFiled: March 15, 2002Date of Patent: December 9, 2003Assignee: Infineum International Ltd.Inventors: Raymond F. Watts, Katherine M. Richard

Patent number: 6478830Abstract: The present invention relates to transparent compositions that may be used as a base material of transparent candles, to the transparent candles made therefrom, and to methods of making such compositions and candles. The compositions of the present invention include a liquid base material; at least one copolymer that includes at least one diblock, triblock, radial block and/or multiblock copolymer or combination thereof; and at least one derivative of an N-acyl amino acid. Preferably the at least one copolymer is a triblock copolymer and the derivative of an N-acyl amino acid is N-lauroyl-glutamic acid di-n-butylamide. The candles of the present invention may be formed into free-standing candles or container candles. The compositions and candles of the present invention may optionally further include one or more of the following: fragrances, coloring agents, decorative materials, insect repellants, solvents, stablilizers, antioxidants, and/or UV blockers.Type: GrantFiled: December 15, 2000Date of Patent: November 12, 2002Assignee: Noville, Inc.Inventors: Gerald Allison, Gilbert Virtucio

Patent number: 5767044Abstract: This is invention relates to a lubricating composition comprising a major amount of an oil of lubricating viscosity, (A) an hydrocarbyl phosphite, wherein each hydrocarbyl group is saturated and independently contains from about 12 to about 24 carbon atoms, (B) an organic polysulfide, and (C) (i) a borated overbased metal salt of an acidic organic compound, (ii) a combination of a borated dispersant and a phosphorus antiwear or extreme pressure agent selected from the group consisting of a phosphoric acid ester or salt thereof, a lower alkyl phosphite, and a phosphorus-containing carboxylic acid, ester, ether, or amide, or (iii) a mixture of (i) and (ii). These compositions provide improved frictional properties to lubricating composition while maintaining the extreme pressure protection of the lubricant. The lubricating compositions have good thermal stability.Type: GrantFiled: November 12, 1996Date of Patent: June 16, 1998Assignee: The Lubrizol CorporationInventors: Sean S. Bigelow, Richard E. Gapinski, Syed Q. A. Rizvi

Patent number: 5089154Abstract: Solid lubricants and a lubricating system having oxidative stability up to about 1500.degree. F. (815.degree. C.) comprising a solid lubricant selected from the group of molybdenum disulfide, graphite and a graphite fluoride having the formula (CF.sub.x).sub.n where x is from about 0.25 to about 1.25 and n is unknown, wherein the solid lubricant is characterized by being microencapsulated from an aqueous system with a thermally and oxidatively stable inorganic resin. Other embodiments of the invention comprise recirculating powder lubricant delivery systems using such microencapsulated lubricants and an encapsulated molybdenum disulfide pyrolyzed at a temperature of from about 400.degree. to about 1000.degree. C.Type: GrantFiled: October 16, 1990Date of Patent: February 18, 1992Assignee: Desilube Technology, Inc.Inventor: James P. King
