Abstract:
An aqueous fluid for the working of metals comprising an aqueous solution of at least one salt of an amido acid of the formula: ##EQU1## in which R is a hydrocarbon group, substituted or not by chlorine, and having between 9 and 25 carbon atoms; n and n' are whole numbers or zero, identical or not, whose sum (n + n') is equal to 1 or 2.
Abstract:
A tire and wheel assembly having a lubricant to enable it to be operated in a deflated condition without destructive heating in which one or more ingredients of the lubricant composition are enclosed in an enclosing means, the other ingredient or ingredients of the composition being placed in the inflation chamber of the assembly. The enclosing means release the first ingredient or ingredients into the inflation chamber, upon loss of inflation pressure, to form the composition.
WHERE R1 and R2 are hydrogen or methyl; R3 and R4 are each an independently selected alkyl group having from 1 to 20 carbon atoms; R5 is the organic residue exclusive of reactive hydroxyl groups of a polyol, p is an integer of from 2 to 6 inclusive and n and m are positive integers independently selected in each chain and whose sum in each chain is from 2 to 20 are prepared by successively reacting boric acid with a glycol monoether and a polyol. These esters are useful as stabilizers and corrosion inhibitors for lubricants and non-aqueous hydraulic fluids.
Abstract:
The addition of a small amount of a soluble salt of perhalometallic or perhalometalloidic acid to an energytransmitting functional fluid sharply enhances the anti-erosion properties of the fluid.
Abstract:
A two-cycle engine oil comprising a polypropylene glycol containing minor controlled amounts of each of a molybdenumcontaining film-strength improver and a halogenated hydrocarbon detergent-film strength improver.
Abstract:
This invention is based on a finding in which an addition of 10 - 30 wt percent of alloy powders to the solid lubricant of graphite-sodium fluoride or graphite-sodium fluoride-tungusten disulfide suitable for use at high temperature contributes to improvements of the mechanical strength as well as the friction coefficient, the preferable alloy being that of the composition of 77Cu-23Pb or 90Cu-5Sn-5Pb. While the addition of 10 - 30 wt percent of a metal salt of tungustate contributes to the formation of strong film or coatings at a high temperature and to prolongation of bearing life.
Abstract:
In the working of non-ferrous metals, particularly zirconium or alloy thereof or titanium or alloy thereof, the improved method of using a mono- or polyamine containing at least 12 carbon atoms as a lubricant.
Abstract:
In the operation of an aluminum rolling mill, in which the lubricant is an oil-in-water emulsion, having an oil phase consisting of a hydrocarbon oil base, containing a free fatty acid and an amino-soap, the average particle size of the oil phase particles is periodically adjusted by the addition to the water phase either of multivalent metallic ion to increase particle size or of an alkali metal soap or material to generate an alkali metal soap by reaction with free fatty acid to reduce particle size so as to retain the particle size within an optimum range.
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:
A hydraulic fluid suitable for use in a tube pressure filter, the hydraulic fluid comprising an aqueous solution of an inorganic salt and an organic material.
