Abstract:
A fibrous grease comprising a base oil and a fibrous diurea thickener comprising the reaction product of toluene diisocyanate, a fatty aliphatic amine and an alkylphenyl amine.
Abstract:
Lubricant compositions adapted for use under extreme pressure, high temperature and high speed conditions comprising a major proportion of an oil or grease base material, having a dropping point above about 300.degree. F., and a minor proportion of an additive system containing as an essential component an inorganic phosphate salt, or mixture thereof, in solid form. Preferred salts are alkaline earth metal ortho- or pyrophosphates exemplified by dicalcium phosphate.
Abstract:
A lubricant composition having special utility as a lubricant in constant velocity universal joints of the type used in front wheel drive vehicles. The composition comprises a low sulfur lubricating oil base grease and an additive package comprising a mixture of an oil soluble, sulfur-free organic compound and an oil insoluble sulfur-free inorganic compound.
Abstract:
Lubricant compositions adapted for use under extreme pressure conditions comprising a major proportion of a lubricating grease, and a minor proportion of an additive consisting essentially of a solid, oil insoluble arylene sulfide polymer, and a metal salt, particularly an alkali metal or alkaline earth metal salt, particularly an alkali metal or alkaline earth metal salt of a phosphorus acid, for example, mono- or dicalcium phosphate, or an alkali metal or alkaline earth metal carbonate exemplified by calcium carbonate, or a mixture of such a phosphate salt and carbonate.
Abstract:
Lubricant compositions adapted for use under extreme conditions comprising a major proportion of an oil or grease base material, and a minor proportion of an aromatic polyamide fibrous substance in an amount sufficient to impart a fibrous texture to the base material.
Abstract:
Lubricant compositions adapted for use in lubricating traction motor gears comprising a major proportion of a base oil such as a mineral oil, and a minor proportion of an oil soluble polymer such as a polyisobutylene.
