Abstract:
Particles each of which consists of an inorganic polyvalent metal compound as a nucleus and a coating of a metallic soap of the polyvalent metal coating the nucleus (coated particles); products and preparation processes using the particles; a lubricating coating forming agent wherein particles each of which consists of a polyvalent metal salt of phosphoric acid as a nucleus and a coating of a metallic soap of the polyvalent metal coating the surface of the nucleus are suspended in an aqueous solution of a water soluble inorganic salt and/or a water soluble organic acid salt; and a lubricating coating. The coated particles are novel particles which can be used as an ingredient of coating-type lubricating coating; are excellent in seizure resistance; can inhibit wear of tools at the time of plastic working since the friction coefficient of the surface of the particles is low; and are slow to cause pollution of working oils. Lubricating coating obtained by applying the lubricating coating forming agent onto the surface of a metallic material gives excellent cold plastic working properties, namely lubricity and seizure resistance to the metallic material.
Abstract:
The present invention provides a new composite material comprising a porous matrix made of metal, metal alloy or semiconducting material and hollow fullerene-like nanoparticles of a metal chalcogenide compound or mixture of such compounds. The composite material is characterized by having a porosity between about 10% and about 40%. The amount of the hallow nanoparticles in the composite material is 1-20 wt. %.
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 mu m to less than 1 mu m and said lubricant having an apparent viscosity within the range of from 1,000 to 50,000 cP.
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:
The invention relates to a lubricant which can be used as a mandrel lubricant with a content of 75 to 90 wt. % of graphite and contains 1 to 10 wt. % of a phosphate. Said lubricant can also contain 1 to 4 wt % alkali silicate, 1 to 10 wt. % bentonite, 0.5 to 1 wt. % silico-phosphate and common solid lubricants. Said lubricant is preferably used as an aqueous suspension with a solid content of 20 to 40 wt. %.
