Patent number: 7358216Abstract: A process is disclosed for manufacturing a lubricant composition comprising combining a superabsorbent polymer with a material for decreasing friction between moving surfaces. The superabsorbent polymer absorbs from about 25 to greater than 100 times its weight in water and may comprise a polymer of acrylic acid, an acrylic ester, acrylonitrile or acrylamide, including co-polymers thereof or starch graft co-polymers thereof or mixtures thereof. A product produced by the process includes the material for decreasing friction comprising a petroleum lubricant containing an additive, water containing an additive, synthetic lubricant, grease, solid lubricant or metal working lubricant, wherein the synthetic lubricant, grease, solid lubricant or metal working lubricant optionally contain an additive. A process comprising controlling the delivery of a lubricant to at least one of two moving surfaces in order to decrease friction between said moving surfaces, is also disclosed.Type: GrantFiled: December 11, 2003Date of Patent: April 15, 2008Assignee: Lee County Mosquito Control DistrictInventor: Richard Levy

Publication number: 20080015123Abstract: The present invention is directed to an apparatus for distributing a cable-pulling composition onto a cable as it is being pulled through a conduit. In one embodiment, the cable pulling composition is a block of an enhanced composition, e.g., consisting essentially of boron nitride that facilitates the pulling of cables through conduits. The invention further relates to a method for pulling cables through conduits by applying an effective amount of boron nitride composition onto the cable surface through the use of the cable-pulling apparatus of the invention.Type: ApplicationFiled: November 1, 2006Publication date: January 17, 2008Applicant: General Electric CompanyInventors: Joerg Student, Rickson Sun, Andy Switky, Jesse Fourt, Mian Ding, Chunlin Yao

Publication number: 20080015122Abstract: The present invention is directed to enhanced compositions that facilitate the pulling of cables through conduits. In one embodiment, the composition comprises a sufficient amount of boron nitride, which, upon application onto the cable surface, allows the cable to be pulled faster and/or with less force through the conduit than without the boron nitride present. The invention further relates to a method for pulling cables through conduits by applying an effective amount of boron nitride composition onto the cable surface. Lastly, the invention relates to an apparatus for distributing a cable-pulling composition comprising a block of boron nitride onto a cable as it is being pulled through a conduit.Type: ApplicationFiled: November 1, 2006Publication date: January 17, 2008Inventors: Joerg Student, Rickson Sun, Gregory W. Shaffer, Donald Lelonis, Paul Hans, Robert Marchiando, Jennifer Klug

Publication number: 20080004191Abstract: A thermal conductive grease used for diffusion of heat generated in electronic appliances is provided. The thermal conductive grease comprises: (A) a base oil having a viscosity of 112 to 770 mm2 at 40° C. and comprising a copolymer of an unsaturated dicarboxylic acid dibutyl ester and an ?-olefin; and (B) a thermal conductive filler filled in the base oil. The thermal conductive grease does not include conventionally used silicone oil so that insulating substances will not be formed in the thermal conductive grease.Type: ApplicationFiled: June 29, 2006Publication date: January 3, 2008Inventor: Tsukasa Ishigaki

Patent number: 7244696Abstract: An anti-seize composition which is non-flowable and dimensionally stable at temperatures greater than about 120° F. and dispensable at room temperature without the application of heat is provided. The composition includes a solid anti-seize lubricant, such as of metallic copper, metallic nickel, metallic aluminum, metallic lead, metallic zinc, graphite, calcium oxide, calcium carbonate, calcium fluoride, calcium stearate, lithium, molybdenum disulfide, boron nitride, barium sulfate, or combinations thereof. The anti-seize lubricant is dispersed in a carrier which is a solid at about room temperature. The carrier includes a grease with an ASTM D 217 penetration at 25° C. from about 200 to about 400 mm, a matrix material, and a naphthenic petroleum oil having a viscosity of less than about 300 SUS at 100° F. and having an API gravity at 60° F. from about 23 to about 25. The matrix material is a polymeric material. Optionally, a refined petroleum wax may also be included.Type: GrantFiled: October 29, 2002Date of Patent: July 17, 2007Assignee: Henkel CorporationInventors: Prakash S. Patel, Shabbir Attarwala

Patent number: 7125499Abstract: Liquid phase liquid crystal polymers (LCPs) are disclosed having a composition and structure that can be varied to provide desirable properties. The liquid phase LCPs have polyiminoborane, polyaminoborane, and/or borozine polymer backbone molecules, with silicon and/or phosphorous side chain molecules linked to the backbone that provide a degree of alignment assigned an Order Parameter (S), defined as S=? [3 cos2 ??1], where ? is the angle between the axis of an LCP molecule and the vertical direction. The inventive liquid phase LCPs have an average Order Parameter in the range of about 0.2 to about 0.99 and are applicable to a number of rinse, coolant, lubricant, sterilization and other protectant processes.Type: GrantFiled: August 12, 2002Date of Patent: October 24, 2006Assignee: LCP Tech Holdings, LLCInventors: Thomas David Ferguson, Rakesh Govind
