Abstract:
A lubricant additive that includes antimony thioantimonate and antimony trioxide in a specified ratio for enhancing the extreme pressure, antiwear, and antiabrasive properties of conventional lubricants as well as for use in lubrication of a wide variety of lubricated contact surfaces.
Abstract:
A process for drawing wire employing a lubricant comprising perfluorocarbon compounds (PFCs), including aliphatic perfluorocarbon compounds ( alpha -PFCs) having the general formula CnF2n+2, perfluoromorpholines having the general formula CnF2n+1ON, 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.
Abstract:
The invention describes an apparatus having an evacuable cavity surrounded by a casing, there being arranged in the cavity and/or on the casing, and projecting into the cavity, at least one friction assembly and/or bearing assembly having at least two elements each having a surface, the two surfaces interacting, and at least one of the two surfaces being coated with a lubricating varnish, at least in the region of their interaction, the varnish comprising a polymeric binder and also molybdenum disulphide (MoS2) and graphite as solid lubricants. The invention further describes an anti-friction paste, an anti-friction dispersion, and the use of a lubricating varnish under high or ultra-high vacuum.
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 stainless steel wire is plated with nickel (Ni) to a thickness of from not less than 1 µm to not more than 5 µm. An inorganic salt coat film mainly composed of at least one of potassium sulfate and borax (borate) and free from fluorine (F) or chlorine (Cl) is then deposited on the nickel (Ni) plate 2 as the substrate. The steel wire is then drawn to a reduction of area of not less than 60% to adjust the surface roughness thereof to a range of from 0.80 to 12.5 µmRz, preferably from 1.0 to 10.0 µmRz.
Abstract:
The present invention provides lubricant compositions for the powder metallurgical field. The lubricant compositions contain a solid phase lubricant such as graphite, molybdenum disulfide, and polytetrafluoroethylene in combination with a liquid phase lubricant that is a binder for the solid phase lubricant. The binder can be chosen from various classes of compounds including polyethylene glycols, polyethylene glycol esters, partial esters of C3-6 polyhydric alcohols, polyvinyl esters, and polyvinyl pyrrolidones. The binder is solubilized in an organic solvent.
Abstract:
A lubricant for use in hot rolling of high chromium stainless steel, the lubricant being continuously supplied to surfaces of hot rolling rolls in contact with the steel being rolled at least during hot rolling of the stainless steel, which lubricant comprises a viscous aqueous solution of water soluble high molecular weight thickener and from 10 to 40% by weight of iron hydroxide powder dispersed in the aqueous solution, said iron hydroxide powder having a median particle size of from not less than 0.1 µm to less than 1 µm and said lubricant having an apparent viscosity within the range of from 1,000 to 50,000 cP.
Abstract:
A recirculating powder lubricant delivery system having improved oxidative stability and a lubricant therefor where the lubricant is a solid lubricant selected from a group of molybdenum disulfide, graphite and graphite fluoride, and wherein the solid lubricant is microencapsulated from an aqueous suspension of an alkali metal silicate containing a water soluble phosphate.
Abstract:
A surface-coated rubber or plastic sliding member having a coating with excellent durability and high slipperiness,wherein the coating comprises a solid lubricant such as molybdenum disulfide, a resin matrix and a reinforcement, said resin matrix comprising a fluoroolefin vinyl ether polymer resin and/or a fluoroolefin vinyl ether/vinyl ester copolymer resin.
