  • Patent number: 4155860
    Abstract: A lubricant additive composition for use with petroleum base lubricant media. The additive is formed of an admixture of about 1 to about 3 parts by weight copper metal flake or powder particles having a size of about 1 to about 2 microns, about 2 to about 4 parts by weight chromium metal flake or powder particles having a size of about 1 to about 2 microns, about 1 to about 3 parts by weight zinc metal flake or powder particles having a size of about 1 to about 2 microns and about 2 to about 4 parts by weight molybdenum disulfide particles having a size of about 1 to about 2 microns.

  • Patent number: 4152276
    Abstract: Ethylene/C.sub.3-12 .alpha.-monoolefin copolymers having an average molecular weight of about 10,000-1,000,000 containing about 1-10 pendent amide and/or ester groups per each 10,000 molecular weight are effective ashless dispersants and impart viscosity lift to lubricating oils.

  • Patent number: 4149981
    Abstract: A method for producing plastic and liquid lubricants characterized by conducting a dispersion of the starting components, such as thickeners or reagents for the formation thereof, additives and fillers and base liquids into a vortical bed of ferromagnetic particles formed under the action of a rotating magnetic field.The proposed method makes it possible to reduce the duration of chemical reactions between the dispersed components of lubricants by thousands of times as compared to the known batch processes and by dozens of times as compared to the known continuous processes. The method provides continuous conduction of technological processes with high productivity, reduces by 10-20% specific consumption of expensive components, by 2-3 times the consumption of energy, and allows the process to be conducted at lower temperatures and pressures.
