Abstract:
A process for preparing a fluid, highly-basic, magnesiumcontaining dispersion, wherein the process comprises: forming an admixture of oil soluble dispersing agent, magnesium oxide, volatile solvent, water, alcohol, and ammonia or ammonium compound, treating the admixture with carbon dioxide, adding to the carbonated admixture a nonvolatile diluent oil, and removing the volatile materials. The process is particularly suitable for preparing large batches of product and, therefore, is suitable for commercial preparation of the product. The product is useful in lubricating compositions for internal combustion engines. Important features of the process are: use of a very small amount of alcohol, use of ammonia or ammonium compound and use of certain types of magnesium oxide.
Abstract:
A method of lubricating a workpiece, especially a wire of steel, titanium, or the like, in a warm forging process such as warm heading performed at a temperature between 450*-800*C, characterized by using an oily lubricant, such as oil, fat, mineral oil and polyethylene glycol mixed with about 5-20 times as much water and spraying the mixture of said lubricant and water by using airless spray at nozzle pressure from 50 to 150 kg/cm2 into engaging surfaces of the workpiece and a tool, whereby due to a cooling effect by the water, the oily lubricant operates satisfactorily even at a high temperature range of 450*800*C.

Abstract:
ORGANIC MATERIALS NORMALLY SUBJECT TO OXIDATIVE DETERIORATION ARE STABILIZED BY INCORPORATING THEREIN A METAL DERIVATIVE OF MONOBASIC OR DIBASIC HINDERED PHENOL SUBSTITUTED PHOSPHONIC ACID AND ONE OR MORE OF THE ADDITIONAL ADDITIVES SELECTED FROM THE PHENOLIC ANTIOXIDANTS, SYNERGISTS, ULTRAVIOLET LIGHT ABSORBERS, ULTRAVOILT LIGHT STABILIZERS, BUFFERS, PIGMENTS, OR DELUSTERING AGENTS, DYES, DYESITES AND PHOSPHITES.
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 APPERANCE OF THE RESINOUS COATING IS MODIFIED BY RISING THE COATING WITH AN AQUEOUS RINSE SOLUTION CONTAINING HEXAVALENT CHROMIUM OR AN AQUEOUS RINSE SOLUTION CONTAINING HEXAVALENT CHROMIUM AND REDUCED FORMS OF CHROMIUM.
Abstract:
An overbased dispersion useful as a lubricating oil additive is prepared by adding a metal alkoxide-carbonate complex to an alcohol or alcohol-aromatic solution of a metal free, oil soluble, neutral or basic dispersing agent containing an acylated nitrogen atom. The dispersing agent is preferably an amide, imide or ester derived from the reaction of a high molecular weight alkenyl carboxylic acid or acid anhydride with an organic nitrogen-containing compound having at least one amino group or hydroxyl group. Concurrently with, or following, addition of the alkoxide-carbonate complex, the complex is hydrolyzed to yield a dispersion of fine particles of metal carbonate. The solvents are then stripped from the dispersion to form a bright, clear composition having a base number of from about 50 to about 250 and useful as an ashless detergent-dispersant additive to lubricating oils.
Abstract:
LUBRICATIING GREASES ARE IMPROVED AS TO BLEEDING, WATER WASH-OUT, AND WHEEL BEARING LEAKAGE PROPERTIES BY THE ADDITION OF A HYDROGENATED BUTADIENE-STYRENE COPOLYMER.
Abstract:
HYDROCRACKED LUBRICATING OILS WHEN TREATED WITH AN ORGANIC PEROXIDE IN THE PRESENCE OF A SYNTHETIC HYDROCARBON LUBRICANT OR ESTER LUBRICANT OR ADDITIVE CONTAINING ABSTRACTABLE HYDROGEN ATOMS PRODUCES PRODUCTS HAVING IMPROVED VISCOSITY PROPERTIES AND OXIDATION STABILITY.
