Abstract:
A process for the lubrication of a tool surface which comprises high pressure blast spraying a powder lubricant having a particle size of 0.6 to 1.5 .mu. at a spray pressure of 4 to 5 bar, onto the tool surface thereby producing a high temperature compacted coherent lubricant film on the surface while simultaneously smoothing, strengthening and compressively stressing the tool surface.
Abstract:
A lubricant composition for use alone or in a lubricating base, comprising a finely divided carbonate of Group IIA metal and a halogenated organic lubricant.
Abstract:
An improved lubricating oil composition comprising a major amount by weight of oil of lubricating viscosity; a minor amount by weight of solid particles effective to improve the lubricating properties of the composition; and a minor amount of a nitrogen containing mixed ester of a carboxy containing interpolymer. This composition provides improved inhibition of sludge and varnish formation in use.
Abstract:
Metal working operations, especially drawing, are facilitated by applying to the metal a composition which provides lubricity thereto and which melts within the range of about 30.degree.-100.degree. C. The composition comprises at least one neutral ester, and preferably a mixture of esters, prepared from polyalkylene glycols and saturated aliphatic alcohols having at least about 10 carbon atoms, and C.sub.12 -.sub.25 aliphatic monocarboxylic acids and C.sub.4 -.sub.20 aliphatic polycarboxylic acids. The preferred ester mixtures are prepared from polyethylene glycols, C.sub.14 -.sub.20 predominantly straight chain alkanols, stearic acid and adipic, azelaic or sebacic acid. Optional ingredients include phosphorus acid salts and anti-oxidants. The composition may be applied in liquid form and solidifies on cooling to normal ambient and storage temperatures.
Abstract:
Beta -Bromo- Beta -nitrostyrene is a preservative for aqueous systems normally subject to spoilage by slime-forming algae, bacteria and fungi microorganisms.
Abstract:
A SOLID LUBRICANT IS FORM OF A MIXTURE COMPRISING ONE PART BY WEIGHT OF HEXAGONAL BORON NITRIDE TO THREE PARTS BY WEIGHT OF SULFUR. A FINELY DIVIDED POWDER OF THE BORON NITRIDE IS DISPERSED IN LIQUID SULFUR BETWEEN THE MELTING POINT AND 160*C., OR BETWEEN 360*C, AND THE BOILING POINT OF SULFUR. THE MIXTURE, IN THE LIQUID OF PASTY STATE, CAN BE APPLIED TO A MATERIAL WITH A SURFACE HAVING RETENTIVE PROPERTIES, AND ALLOWED TO COOL TO FORM LUBRICATING LAYER.
Abstract:
NOVEL COMPOSITIONS OF MATTER FORMED OFAMMONIUM AND NON-HEAVY METAL INORGANIC SALT AND HYDROXIDE INTERCALATES AND HEAVY METAL LAYERED CHALCOGENIDES, WHEREIN THE CHALOCOGEN IS SELECTED FROM SULFUR, SELENIUM AND/OR TELLURIUM. THE NOVEL INTERCALATED COMPOUNDS DISPLAY ADVANTAGEOUS CHARACTERISTICS WHEN UTILIZED AS SOLID LUBRICANTS, AND AS X-RAY DIFFRACTION GRATING CRYSTALS. CERTAIN OF THE INTERCALATED TRANSITION METAL CHALCOGENIDES ALSO EXHIBIT UNIQUE SUPERCONDUCTIVITY CHARACTERISTICS.
Abstract:
An improved gas turbine regenerator seal system having a new configuration wherein one of the rubbing seal members thereof carries a new material providing an initial working surface comprised of an iron oxide matrix containing an interspersed mixture of boron nitride, nickel coated graphite and sodium sulfate - Na2SO4, sodium phosphate - Na3PO4, or calcium fluoride - CaF2.
