Abstract:
This invention provides a coating for zinc coated steel surfaces and other zinc containing alloys, including zinc/iron, zinc/nickel, zinc/cobalt, zinc/aluminum, and any other suitable metal surface. The coating product of this inventions contains the following ingredients: copolymers made from acrylic, vinylacrylic, and acrylstyrene monomers, has carboxylic radicals from acrylic and/or methacrylic acids, and has an Ia of 30 to 60 mg. of KOH. The water soluble copolymers and lubricatory additives, which include natural or synthetic waxes, graphite, and molybdenum sulfide, are in solid form dispersed in aqueous solution at a ratio of from 1 to 10%.
Abstract:
In a method of lubrication between two sliding members at least one of which is made of a ceramic material, the improvement according to the present invention is characterized in that soot as produced by burning a hydrocarbon fuel is supplied between the two sliding members.
Abstract:
A die-casting powdery mold releasing agent according to this invention is a mold releasing agent comprising a mixture of powdery or granulated mold releasing base material composed of an inorganic compound as used for lubricant in a solid form and an organic compound giving adhesive property to the mold releasing agent, the both having powdery or granulated configurations, or configurations in which the organic compound is covered on the mold releasing base material. The mold releasing agent allows production of castings of high quality, in the die-casting method with good workability and without worsening environmental situations.
Abstract:
A lubricant composition comprised of (A) fatty acid, (B) polytetrafluoroethylene fluorocarbon resin powder (C) pyrogenic amorphous silica powder and (D) carrier. The lubricant is prescribed for use with a pneumatic tire and wheel assembly containing a run-flat device. The lubricant is contemplated as a component in such an assembly.
Abstract:
A bearing element for at least one adjustable guide vane of a turbomachine, in particular an aircraft engine, is provided. The bearing element comprising a porous matrix made of carbon and/or graphite and at least one metallic phase or a metal salt that is at least partially arranged inside the pores of the matrix, so that what results is a metal-infiltrated or a metal-salt-infiltrated material.
Abstract:
The present invention provides a refrigerator oil composition comprising a base oil which is at least one member selected from mineral oils and synthetic oils, and at least one imide compound, said imide compound in an amount of 0.01 to 5% by mass based on the total amount of the refrigerator oil composition, and also provides a compressor and a refrigeration apparatus using the refrigerator oil composition. The refrigerator oil composition and the compressor and the refrigeration apparatus using the refrigerator oil composition satisfy both sludge dispersibility and prevention of wear and seizing of a sliding part made of aluminum and/or iron.

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.
