Abstract:
This invention relates to an aqueous drilling fluid containing a tall oil fraction as a lubricating additive, a method of drilling with said drilling fluid containing said tall oil lubricating additive and the tall oil lubricating additive per se.
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:
A machining fluid includes a basic component in the form of an aqueous solution and an aliphatic acid organic compound which is produced by a fermentation process comprising cultivating a microorganism in a culture medium containing a saccharide, nitrogen source and an inorganic salt and accumulated in a culture broth and separated and recovered from the culture broth.
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:
Method and composition for applying a coating to a metallic surface, the surface being immersed in an acidic aqueous coating composition comprising dispersed solid particles of an organic polymeric resinous coating-forming material and an oxidizing agent, wherein the weight or thickness of the coating formed on the surface is a function of the time the surface is immersed in the composition.
Abstract:
A grease compound of a base oil, a thickener, and minor synergistic amounts of the extreme pressure agent combination of zinc dialkyldithiophosphate, the reaction product of butyl acid phosphate and dodecyl aniline, and Bis(.beta.-chlorophenethyl) disulfide.
Abstract:
A metallic surface is coated with a polymeric resinous coating by immersing the surface in an acidic aqueous coating composition comprising polymeric resinous coating-forming material and an oxidizing agent. The corrosion resistance and/or the surface appearance of the resinous coating is modified by rinsing the coating with an aqueous rinse solution containing hexavalent chromium or an aqueous rinse solution containing hexavalent chromium and reduced forms of chromium.
Abstract:
A lubricant composition comprising water, graphite, an organic thickener, sodium molybdate, and sodium pentaborate. Other additives are sodium bicarbonate, ethylene glycol, or mica. The composition is effective in the hot forging of metals, is virtually non-flammable, and generates very little atmospheric pollution during use.
Abstract:
A method of cold forming ferrous metals is disclosed employing as a cold-forming lubricant a dry solid coating comprising a film of a chlorine-containing, film-forming polymer and a destabilizing agent applied to the surface of a ferrous metal workpiece, which surface is free from other coatings or surface treatment, said coating being applied as a liquid composition and to particular coating compositions.
