Abstract: A method of lubricating a railroad track comprising the steps of dispersing together a mixture of at least 30% by weight of powdered graphite having an average particle size of not larger than 50 microns, and an oil based carrier to yield a viscosity of approximately 25,000 centipoise at standard temperature and pressure; applying said dispersion to a railroad track and pressure fixing to form a film like coating thereon.

Abstract: This invention relates to the production of a unique class of granular graphitic carbon materials containing metallic elements dispersed throughout the graphitic structure. More specifically, the unique class of products contain elements that enhance the controlled nucleation of dissolved carbon during the solidification of molten cast irons and are of particular value in the manufacture of quality iron castings. Moreover, the chemical form of the selected metallic elements and their high degree of dissemination within and throughout a graphitic carbon structure has been shown to provide special properties that increase the controlled nucleating or "inoculating" ability of the products of this invention over that obtained by use of the components added individually or in a simple mixture to molten cast iron.

Abstract: The present invention is directed to a reaction product of silica sand and of particulate carbonaceous material to form, silicon carbide on the surface of the carbonaceous particles and within the pores thereof, with the silicon carbide ultra-microcrystallites having a diameter of approximately 500 Angstroms and the composition comprising approximately 60% silicon carbide. The present invention is further directed to the process by which the ultra-microcrystallite silicon carbide product is made. In other preferred embodiments the ultra-microcrystallites of silicon carbide may be separated from the carbonaceous material by heat or physical methods to form a substantially pure ultra-microcrystallite silicon carbide product.

Abstract: One aspect of the present invention relates to methods for the continuous production of silicon carbide and other carbide and refractory products by fluidized bed techniques, the apparatus for such continuous production, and the carbide products produced therefrom being further aspects of the present invention.

Abstract: One aspect of the present invention concerns an improved process for the electrolytic reduction of a metal from a metal compound and comprises the steps of providing a carbon cathode within a container, dissolving the metal compound in a molten salt electrolyte solvent bath which is disposed within the container, the molten electrolyte bath having a higher decomposition potential than the metal compound and having a lesser density than the reduced molten metal, and continuously providing a particulate, free-flowing, high purity, and highly conductive carbon material to the molten bath to serve as the anode, the particulate carbon material having a lesser density than the molten bath, placing an electrical connection in contact with the particulate carbon anode material and applying an electric current thereto, and collecting reduced metal at the cathode.
