Patent number: 7741257Abstract: The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.Type: GrantFiled: March 15, 2005Date of Patent: June 22, 2010Assignee: Ecolab Inc.Inventors: Arturo S. Valencia Sil, Lawrence A. Grab, Bruce E. Schmidt, David A. Halsrud, Guang-Jong Jason Wei, Eric D. Morrison, Hector R. DiBenedetto

Patent number: 6794342Abstract: In a grease composition which essentially comprises a base oil and a thickener, a mixture of a urea compound and lithium soap is blended as the thickener. The content of the urea compound in the thickener is preferably set to 20 to 80 wt %. As the urea compound, an alkyl group- or cyclohexyl group-terminated diurea compound, or, particularly, a diurea compound in which the diisocyanate component is 4,4′-diphenylmethane diisocyanate is preferably used. In a rolling bearing which is lubricated by the grease composition, the acoustic performance is largely improved by a synergistic action of the lithium soap and the urea compound, and simultaneously also the anti-fretting property is enhanced by an action of the urea compound.Type: GrantFiled: March 14, 2002Date of Patent: September 21, 2004Assignee: Koyo Seiko Co., Ltd.Inventors: Hiroshi Komiya, Atsushi Yao, Nao Ito, Youzou Taniguchi
