Abstract:
Lubricating oil compsn. (I) consists of: (a1) 0-80 (wt.%) glass powder; (a2) 0-50 glass frit, where one of (a1) or (a2) is hot 0 wt .%; (b) 10-25 natural or synthetic graphite; (c) 5-20 alkali silicates of formula: Me2OnSiO2 (where Me = Li, K or Na; and n = 1-4); (d) 1-6 water-soluble Na-polymetaphosphate; (e) 0-3 water-insoluble Na-polymetaphosphate; (f) 0.5-4 thickener; and (g) 0-1 borax.
Abstract:
Thin impermeable, surface hardened, corrosion-resistant, durable, dry lubricant surface finishes are provided as well as surface finished products and methods for the production thereof. The surface finishes comprise particulate mixtures of sulfur containing metallic compounds and fluorocarbon polymers and are applied to surfaces of substrates such as metallic surfaces.
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:
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 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. %.
