Abstract:
Abstract of DisclosureA 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, and acrylic ester, acrylonitrile or acrylamide, including co-polymers thereof or starch graft copolymers 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. This process includes applying the lubricant composition to at least one of the surfaces. The lubricant composition in this instance comprises a superabsorbant polymer combined with a material for decreasing friction between moving surfaces, wherein the material for decreasing friction comprises a petroleum lubricant, water, synthetic lubricant, grease, solid lubricant or metal working lubricant, and optionally an additive.

Abstract:
A method for treatment of bacterial infections with rifalazil administered once-weekly or twice-weekly. A method for treatment of tuberculosis caused by Mycobacterium tuberculosis, infections caused by Mycobacterium avium complex, infections caused by Chlamydia pneumoniae and infections caused by Helicobacter pylori by administering to a patient suffering from the bacterial infection 1-100 mg of rifalazil once or twice a week. In this dose regimen, the treatment is fast, efficacious and eliminates undesirable secondary symptoms observed with daily doses of 1-50 mg of rifalazil.
Abstract:
A hemispherical bearing apparatus includes a MoS.sub.2 layer formed to a predetermined thickness on the surface of a hemispherical recessed portion formed in a bushing or on the surface of a hemispherical member opposed to the recessed portion. The hemispherical bearing apparatus is capable of enhancing the productivity and reducing the fabrication cost. The method for forming the MoS.sub.2 layer may vary with the material of the bushing and the hemispherical members. The MoS.sub.2 layer may be applied by a coating technology or an impregnating technology.
Abstract:
Boric acid-containing lubricants are disclosed which consist essentially of boric acid and at least one other powder metallurgy lubricant and provide a synergistic free-flowing composition. There are also provided novel compositions of matter for forming sintered metal components comprising a mixture of sinterable, powdered metal and the said lubricants.
Abstract:
A self-lubricating solid coating that contains three layers of lubricants is disclosed. The solid lubricant may be prepared from chromium silicide or chromium carbide; disulfide and diselenide of tungsten, molybdenum, niobium, or tantalum; and silver or gold. This material combination provides superior wear and friction reduction over the temperature range applied. In this invention, chromium silicide or chromium carbide is a hard lubricant with a low wear property to protect the substrate metal; disulfide or diselenide is a soft lubricant with a very low coefficient of friction; and silver or gold with their high thermal conductivity are effective in conducting heat especially at high sliding velocities. Both silver and gold have a low friction coefficient with high oxidative stability. The use of this solid lubricant allows engine manufacturers to develop high temperature engine and partially or totally eliminate the use of liquid lubricants in engines, thus reducing the environmental pollution caused by liquid lubricants in various engines.
Abstract:
A process for drawing wire employing a lubricant comprising perfluorocarbon compounds (PFCs), including aliphatic perfluorocarbon compounds (.alpha.-PFCs) having the general formula C.sub.n F.sub.2n+2, perfluoromorpholines having the general formula C.sub.n F.sub.2n+1 ON, perfluoroamines (PFAs) and highly fluorinated amines (HFAs), and perfluoroethers (PFEs). Such fully and highly fluorinated carbon compounds exhibit a very high degree of thermal and chemical stability due to the strength of the carbon-fluorine bond. Further, because the compounds are fully fluorinated, and therefore do not contain chlorine and bromine, they have zero ozone depletion potential (ODP). Further, because the compounds are photochemically non-reactive in the atmosphere, they are not precursors to photochemical smog and are exempt from the United States Environmental Protection Agency (EPA) volatile organic compound (VOC) definition. Further, because they are volatile, the compounds are easily removed at the end of the process without need for an additional cleaning step. The process provides wire at significantly higher production speeds and longer die life with improved quality and less byproduct debris.

A method of manufacturing a galvanized steel sheet with high press formability, the sheet having an inorganic compound on a metallic galvanized-layer thereof. The method includes the step of effecting a galvanization on a steel sheet followed by an alloying treatment. The sheet of galvanized steel is immersed in a bath of an aqueous solution containing 0.1 wt % or more of borate of an alkali metal, and then taking the steel sheet out of the bath and effecting such control as to make the amount of deposition of the water-containing borate film on the steel sheet surface to range from 10 to 1,000 mg/m.sup.2, and then heating the steel sheet at a temperature ranging from 60.degree. to 400.degree.
