Abstract:
A process for the production of an aqueous lubricant composition free of oil including water and at least one metallic carboxylate, wherein the anionic is at least one saturated linear organic radical containing at least 12 carbon atoms and the cationic is at least one bivalent or trivalent metal having an electro-chemical oxidation-reduction potential greater than -0.7 volts. The process includes mixing of two mother solutions. The first mother solution is an aqueous solution of at least one alkali metal carboxylate soluble in water wherein the anionic is at least one saturated linear organic radical with at least 12 carbon atoms. The second mother solution is an aqueous solution of at least one metallic salt whereof the anionic is selected from the group consisting of hydroxide, chloride, sulphate, nitrate or phosphate ions and whereof the cationic is at least one bivalent or trivalent metal having an electro-chemical oxidation reduction potential greater than -0.70 volts.

Abstract:
A fiber preparation containing or consisting of a tertiary butyl ether of the general formula ##STR1## in which R.sub.1 is a straight-chain or branched C.sub.12 -C.sub.22 -alkyl or alkenyl group.
Abstract:
Synthetic fibers are treated for the purpose of lubrication with a compound of the formula: ##STR1## wherein R.sub.1 is hydrogen or phenyl, R.sub.2 is an alkylene group having 1 to 3 carbon atoms, R.sub.3 is an alkylene group having 2 to 4 carbon atoms or a mixed alkylene group thereof, R.sub.4 is hydrogen, an acyl having 1 to 18 carbon atoms or alkyl group having 1 to 18 carbon atoms, p is a number of from 2 to 5 and n is a number of from 1 to 50.
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.
