Abstract:
A composition for lubricating a metal workpiece prior to cold forming consists essentially of: an aqueous alkaline stearate compound present in an amount sufficient to impart metal lubrication between about 180.degree. F. and about 320.degree. F.; an aqueous alkaline palmitate compound present in an amount sufficient to impart metal lubrication below about 160.degree. F.; an aqueous metallic stearate compound present in an amount sufficient to impart metal lubrication between about 320.degree. F. and 440.degree. F.; a polymeric glycol present in an amount sufficient to provide temperature stability, act as a carrier for the aqueous compounds, and impart a waxy lubrication to the metal; a compound present in an amount sufficient to act as a carrier for the aqueous compounds and to provide a translucent film barrier on the metal; an alkaline buffering agent present in an amount sufficient to provide dispersion, viscosity and stability; a hydrotropic agent present in an amount sufficient to solubilize the lubricating composition. A process is disclosed for lubricating a metal workpiece outer surface prior to cold forming, the process comprising the step of disposing a non-reactive lubricating composition on the workpiece outer surface, the outer surface having been alkaline cleaned, hot water rinsed, acid pickled, and cold water rinsed.

Abstract:
Multifunctional additives having a variety of advantageous properties are described. They are formed by a process which comprises heating concurrently or in any sequence a) an oil-soluble ashless dispersant containing basic nitrogen with b) an alkoxylated alcohol of at least 8 carbon atoms c) a borating agent and optionally d) an inorganic oxyacid or anhydride of phosphorous. The reactants are in proportions on an active ingredient basis of about 0.03 to about 0.35 part by weight of b) per part by weight of a), and about 0.005 to about 0.06 part by weight of boron as c) per part by weight of a). The reaction temperature can range from about 50.degree. to about 150.degree. C. Water and/or solids present in the resultant mixture can be removed. Preferably, the optional phosphorous component is used in the formation of these additives. This phosphorous component can be an inorganic oxyacid or anhydride of phosphorous.
Abstract:
A lubricant composition including ethoxylated long chain primary alcohols and, preferably, boron compounds but excluding most other previously used organic lubricant materials gives superior results in tube pointing operations, especially with thick walled tubes, and is also useful for drawing operations, either subsequent to pointing or independently of pointing, where very high quality surface finishes are desired.
Abstract:
A coating and bonding composition is disclosed which includes a suspending agent, bonding agent, thinning agent, and a metallic flake designed to bond a dissimilar metal to the thread surface to prevent seizing and galling.
Abstract:
A stearate free solid lubricant for cold working of metals contains approximately equal amounts of an alkene-acrylate ionomer and an alkoxylated alcohol in which the alcohol moiety has from 18-60 carbon atoms and the alkoxylate block has about the same number of carbon atoms. This lubricant can be conveniently applied from aqueous solution/suspension and works effectively even when the underlying steel surface has no conversion coating, which is usually required with stearate lubricants for best results.

Abstract:
The invention includes a lubricating composition comprising a major amount of an oil of lubricating viscosity, and a minor amount of (A) a sulfite or sulfate overbased or borated overbased metal salt of an acidic organic compound, wherein the lubricating composition contains less than 1.5% by weight of the reaction product of a polyisobutene substituted succinic anhydride and a polyamine, and provided that when (A) is a sulfate overbased or borated overbased metal salt, then the lubricating composition includes (B) at least one phosphorous of boron antiwear/extreme pressure agent, or (C) a sulfur compound. The invention also includes grease and functional fluids containing the sulfite and sulfate overbased metal salts. These composition have improved antiwear, antiweld, and extreme pressure properties.

Abstract:
The invention generally relates to gelled oil compositions which employ aluminum complex soaps as gelling agents. The gelled oils comprise an oil component, a bleed inhibitor of polybutene, and optional amounts of antioxidant and pour point depressant. The gelled oils are particularly suited for use as buffer tube gels and as filling compounds for waveguides.
