Abstract:
The invention concerns a threaded portion of a tubular element for a threaded tubular connection having an axis of revolution, the portion comprising a threading extending over its outer or inner peripheral surface, and a first sealing surface on the peripheral surface, the first sealing surface being capable of producing metal-metal interference with a corresponding second sealing surface belonging to a complementary threaded portion. The threading and the first sealing surface are coated with a metallic anti-galling layer wherein zinc (Zn) is the major element by weight, the metallic anti-galling layer being at least partially coated with a lubricant layer comprising a resin and a dry solid lubricant powder dispersed in the resin.
Abstract:
A method for preparing an estolide compound and an estolide compound prepared thereby are disclosed. The method for preparing an estolide compound includes: converting biomass fat into a fatty acid; separating the fatty acid into a C16 saturated fatty acid and a C18 unsaturated fatty acid; preparing a linear internal olefin (LIO); increasing an amount of oleic acid through partial hydrogenation of the C18 unsaturated fatty acid; synthesizing an estolide polymer through cross metathesis of the oleic acid; capping the C16 saturated fatty acid onto the estolide polymer; and reacting the estolide polymer with the linear internal olefin.
Abstract:
Polyol ether derivatives, a method for producing the polyol ether derivatives, and a working fluid composition for a refrigerating machine containing a hydrofluorocarbon and a refrigeration oil containing the polyol ether derivatives as a base oil.

Abstract:
A process for preparing an aqueous gel which comprises mixing a water-soluble acetoacetylated high molecular compound, a cross-linking agent and water, thereby cross-linking said high molecular compound to form an aqueous gel. According to the process of the invention, an aqueous gel having excellent transparency and small serum-separation, can be prepared at room temperature by only mixing. Also, according to the present invention, there are provided the aqueous gel composition containing perfume or deodorant, and the lubricant and the method for use thereof, which utilizes the process of claim 1.
Abstract:
A composition useful in isothermal forging or sizing of metal articles comprising a major amount of a glass moiety fusible at a temperature below forging or sizing temperature, and a minor amount of a finely divided abrasive moiety dispersed in the glass moiety and having a predetermined hardness.
Abstract:
An oil-well metal pipe according to the present disclosure has a pipe main body including a first end portion and a second end portion. The pipe main body includes a pin formed at the first end portion, and a box formed at the second end portion. The pin includes a pin contact surface including an external thread part, and the box includes a box contact surface including an internal thread part. The oil-well metal pipe according to the present disclosure also includes a resin coating containing a resin, a solid lubricant powder, and copper phthalocyanine on or above at least one of the pin contact surface and the box contact surface.
Abstract:
The invention relates to a solid compressed lubricating member for a razor cartridge comprising from 10% to 90% by weight of a particulate material comprising water soluble polymer and from 12% to 40% by weight of a hydrophobic compound or mixtures thereof; wherein at least a portion of said water soluble polymer particulate is spray coated with said hydrophobic compound and methods of manufacture thereof.
Abstract:
This invention relates to a hydroxyaromatic functionalized polyalpha-olefin comprising the product of the combination of: a) a polyalpha-olefin comprising one or more C3 to C20 linear alpha-olefins and having at least 10% vinylidene unsaturation, a viscosity index of 80 to 400, an Mn of 300 to about 20,000, and a pour point of 0° C. or less; and b) a hydroxyaromatic moiety; wherein the analine point of the functionalized polyalpha-olefin is at least 10° C. lower than the analine point of the polyalpha-olefin.
Abstract:
A lubricating oil composition comprising: (A) a base stock; and (B) a liquid additive package. The liquid additive package comprises: (i) an alkylated diphenylamine; (ii) at least 5 weight % of a phenyl naphthylamine, based on the weight of the additive package; and (iii) a sulfur-containing phenol.
