  • Patent number: 4663061
    Abstract: A metal-working oil composition containing the following three components (A), (B) and (C) as its essential components:(A) one or more lube-oil components selected from the group consisting of oils, fats, mineral oils and fatty acid esters;(B) a cationic or amphoteric water-soluble polymer compound having a molecular weight of 1,000 to 10,000,000, containing nitrogen atoms in its molecule; and(C) a surfactant.A metal-working oil composition according to the invention can further and optionally comprise an extreme-pressure additive, which can enhance the lubrication performance. When the metal-working oil composition is brought into contact with a metallic workpiece, oil droplets having a uniform diameter form a thick and strong lubricating film over the workpiece, thus the composition can be successfully employed for processing metals under high shear, high-speed and high-pressure conditions.

  • Patent number: 4349444
    Abstract: A hybrid lubricant in which microfine PTFE particles are uniformly dispersed in an oil carrier that includes a small but effective amount of an oil-soluble organic molybdenum compound, the hybrid lubricant being diluted with a major amount of a conventional lubricating oil. In operation, a thin film of the molybdenum compound is developed on the rubbing metal surfaces of the lubricated engine, the film reacting in the high-temperature, high-pressure environment of the rubbing surfaces to form a fluoride to which the PTFE particles bond to impart thereto an extremely low coefficient of friction to afford the benefits of both solid and fluid lubrication. The hybrid lubricant minimizes friction under all operating conditions regardless of their severity, and it reduces wear on the engine.

  • Patent number: 4333840
    Abstract: A lubricant especially adapted to meet the requirements of firearms, the lubricant being constituted by a dispersion of microfine PTFE particles in an oil carrier diluted with a major amount of synthetic lubricant having a low viscosity and a high viscosity index, whereby the resultant hybrid lubricant not only reduces wear and friction, but also affords a protective coating for the treated metal surfaces which resists the adhesion thereto of grime, powder, lead and all other contaminants that otherwise make it necessary to frequently clean the weapon to maintain it in proper working order.

  • Patent number: 4332593
    Abstract: Mine run coal is pulverized and the extended surfaces of the coal particles are rendered hydrophobic and oilophilic by a chemical bonding and graft polymerization reaction with a water insoluble organic polymerizable monomer under peroxidation influence in a predominantly water reaction medium.The mineral ash present in the coal and particularly the iron pyrites remains hydrophilic and is separated from the polymeric organic surface bonded coal product in a water washing step wherein the washed coal floats on and is recovered from the water phase and the ash is removed with the separated wash water in a critical wash step.Excess water is removed from the beneficiated hydrophobic surface-altered coal product mechanically. The hydrophobic and oilophilic organic polymeric surface bonded coating about the coal particles is fortified by inclusion of additional unbound free fatty acids by further small additions thereof.

  • Patent number: 4319886
    Abstract: This patent discloses a new class of denaturants for commercial ethyl alcohol, particularly for use in mixtures such as Gasohol. These denaturants are the lower alcoholic esters of monocyclic naphthenic acids and are particularly useful because they can be added in very low concentrations and still provide a noxious flavor and odor to the alcoholic system to make it non-potable.
