In accordance with one implementation, a lubricant comprises food grade based oils substantially complying with USDA H-1 specifications for incidental contact with food, wherein at least one oil is selected from the group consisting of food grade plant oil, food grade poly-alpha-olefin, polyalkylene glycol, and mixtures thereof. In accordance with another implementation, a lubricant comprises canola oil, castor oil and a poly-alpha-olefin. In accordance with yet another implementation, a lubricant comprises canola oil, castor oil and a polyalkylene glycol. In accordance with yet another implementation, a lubricant comprises an oil substantially complying with USDA H-2 specification wherein the oil is at least one item selected from the group consisting of plant oil, poly-alpha-olefin, polyalkylene glycol, and mixtures thereof. In some implementations, the multi-purpose lubricant may be applied to areas of a bicycle chain.Type: ApplicationFiled: December 12, 2012Publication date: June 12, 2014Inventors: Mark Brandon Shiflett, Kurt Richard Mikeska

Publication number: 20040053792Abstract: A conveyor lubricant composition comprises water, a viscosity modifier at a concentration of from 0.01% to 5% by weight of the composition, and a humectant. A surfactant and a biocide are preferably included in the composition, and the humectant is preferably included at a concentration of 10 to 40% by weight of the composition. The composition is superior to conventional aqueous soap- and detergent-based lubricants.Type: ApplicationFiled: February 25, 2003Publication date: March 18, 2004Inventor: Christopher William Wederell

Publication number: 20030186824Abstract: A biodegradable lubricant that is at least 60% biodegradable and has a gelation index of about 12 or less can be formulated using a transesterified triglyceride base oil together with a synthetic ester. A combination of an ester viscosity index improver and an olefin copolymer viscosity index improver also can be added. Further, the composition can be blended with mineral oils to lower the polarity in order to employ standard dispersant/inhibitor packages. Further, by mixing high and low viscosities of mineral oil in the formulation, it is possible to prepare a full range of SAE grade engine oils for gasoline-fueled and diesel-fueled engines.Type: ApplicationFiled: September 24, 2002Publication date: October 2, 2003Applicant: Pennzoil-Quaker State CompanyInventors: I-Ching Chiu, Selda Gunsel, Paul Lacey

Patent number: 6485659Abstract: The present invention comprises a mixture of hydrocarbons having a well-defined chemical composition that is suitable for use as a dielectric coolant in electrical equipment in general, and specifically in transformers. The dielectric coolants of the present invention are particularly suited for use in sealed, non-vented transformers, and have improved performance characteristics, including decreased degradation of the paper insulating layers, as well as a greater degree of safety and environmental acceptability. The present dielectric coolants comprise relatively pure blends of compounds selected from the group consisting of aromatic hydrocarbons, polyalphaolefins, polyol esters, and natural vegetable oils, along with additives to improve pour point, increase stability and reduce oxidation rate.Type: GrantFiled: June 16, 1998Date of Patent: November 26, 2002Assignee: Cooper Industries, Inc.Inventors: Gary L. Goedde, Gary A. Gauger, John Lapp, Alan Paul Yerges
