  • Patent number: 4383931
    Abstract: The antifriction properties of a lubricating oil are enhanced by the addition of a minor amount of an oil-soluble molybdenyl bis-.beta.-diketonate. The antifriction properties are particularly enhanced when the molybdenyl bis-.beta.-diketonate is used in combination with an oil-soluble active sulfur donor, such as a zinc dialkyldithiophosphate.

  • Patent number: 4382137
    Abstract: Novel resin products produced by reacting unique polycyclic, aromatic, polycarboxylic acid products with low molecular weight polyols display satisfactory toughness properties and good Barcol hardness values. The process for preparing these novel resin products first involves preparing an intimate, finely divided mixture comprising the acid product derived from the nitric acid oxidation of naturally occurring solid carbonaceous material, a roughly equivalent amount of a liquid polyol, and a suitable acid catalyst. The mixture is then subjected to a precure step which involves heating at temperatures between 80.degree. and 150.degree. C. for from about fifteen minutes to about four hours. The precured mixture may thereafter be subjected to suitable molding conditions at a temperature below about 220.degree. C.

  • Patent number: 4378048
    Abstract: Low heating value gases are combusted substoichiometrically in two combustion zones in series in contact with two different supported platinum catalysts in which the concentration of platinum in the catalyst in the first zone is higher than the concentration of platinum in the second catalyst. The combusted gas of reduced carbon monoxide can be directly vented to the atmosphere after energy has been extruded from it for a useful purpose.

  • Patent number: 4376061
    Abstract: There is provided a solid, particulate, catalytic complex suitable for the stereospecific polymerization of olefins prepared by reducing TiCl.sub.4, contacting the resultant reduced solid with a complexing agent to obtain a treated solid and contacting the treated solid with TiCl.sub.4 in the presence of silica which has been treated with an alkylaluminum halide. When such a catalyst complex is combined with a suitable activator to polymerize olefins, a high degree of stereospecificity is attained, the activity of the catalyst complex is reduced for polymerization control and the efficiency of the titanium employed is enhanced.

  • Patent number: 4370253
    Abstract: A stable, isotropic emulsion of a water-insoluble material comprising alkenylsuccinic acid-in-water is prepared without an emulsifying agent. The emulsion is prepared by heating an admixture of a water-insoluble material comprising less than 95 weight percent alkenylsuccinic acid and water at a temperature of at least about 50.degree. C., cooling the heated mixture to below about 30.degree. C. and subjecting the cooled mixture to brisk agitation at a temperature below about 40.degree. C. to form a stable emulsion. The remaining water-insoluble material can be an oleophilic material, such as high molecular weight olefins, paraffin wax, long chain alkyl aromatics, pine oil, or the like. The average particle diameter of the emulsion particles is less than about 30 microns.
