Mineral Oil-containing Patents (Class 585/6.6)
  • Patent number: 8318846
    Abstract: An object of the present invention is to provide an olefin-based thermoplastic elastomer composition that has both weatherability and flexibility at low temperatures, is excellent in fluidity, and causes no stickiness even in the use at high temperatures; a process oil composition for elastomers that serves as the raw material of the thermoplastic elastomer composition and contributes to the above characteristics; and an oil-extended elastomer containing the process oil composition. The process oil composition for elastomers of the present invention has a property that, when 20 parts by weight of the process oil composition for elastomers are blended with respect to 100 parts by weight of a propylene homopolymer, the melting point of the propylene homopolymer is lowered by 2 to 4.5° C. compared to that of the propylene homopolymer without blending.

  • Patent number: 7682499
    Abstract: The invention provides for a mineral insulating oil having a naphthenic base oil and a paraffinic base oil wherein the naphthenic base oil includes a ratio of total sulfur to basic nitrogen of less than about 80:1. The invention also provides for a mineral insulating oil having a naphthenic base oil, a paraffinic base oil, and an antioxidant agent wherein the naphthenic base oil includes a ratio of total sulfur to basic nitrogen of less than about 80:1. The invention also provides for a process for producing a mineral insulating oil including contacting a naphthenic base oil and a paraffinic base oil wherein the naphthenic base oil includes a ratio of total sulfur to basic nitrogen of less than about 80:1. The invention also provides for a process for producing a mineral insulating oil including contacting a naphthenic base oil, a paraffinic base oil, and an antioxidant agent wherein the naphthenic base oil includes a ratio of total sulfur to basic nitrogen of less than about 80:1.

  • Patent number: 6632970
    Abstract: The present invention deals with the catalytic hydrogenation of fluid used to cool and dielectrically insulate an x-ray generating device within an x-ray system. According to the present invention, a method and apparatus are provided for hydrogenating fluid that has been exposed to x-rays to reduce the amount of H2 gas, free hydrogen atoms and unsaturated molecules in the fluid. The method comprises exposing the fluid within the x-ray system to a catalytically effective amount of catalyst. The catalyst operates in temperatures in the range of about 10-300° C. and pressures in the range of about 0.1-30 atmospheres. The catalyst may comprise a solid, non-soluble catalyst, a soluble catalyst, or a combination of both. A suitable solid, non-soluble catalyst comprises Group VIII elements and their compounds. Group VIII elements comprise iron, cobalt, nickel, ruthenium, rhodium, palladium, osmium, iridium and platinum.

  • Patent number: 6355850
    Abstract: Electrical oils having improved uninhibited oxidation and electrical resistance are derived by blending a substantially nitrogen and sulfur free paraffinic or naphthenic base oil with a hydrofined light gas oil having a sulfur to nitrogen weight ratio of greater than 100:1 wherein the hydrofined light gas oil is added to the base oil in an amount sufficient to provide a blend having greater than about 0.03 wt % sulfur.
