Abstract: A method for producing essentially spherical dry pellets largely comprising combustible materials, a method for using the pellets as cores by uniformly coating them with a ceramic-forming powder and sintering the powder to volatilize the combustible core material and form hollow ceramic balls, and a method for using the balls as catalyst supports by coating them with platinum and palladium salts and reducing the salts to elemental metals so that satisfactory oxidizing catalysts are obtained. When the ceramic is an aluminosilicate such as mullite, satisfactory oxidizing catalysts are obtained that pass the bulk density, crush strength, dust-free surface, and oxidizing temperature requirements of specifications developed to meet automobile exhaust emission requirements.

Abstract: A carbothermic process for the production of aluminum contaminated with no more than about 10 weight percent of aluminum carbide is disclosed which involves charging alumina values and carbon values into a furnace and subjecting only a minor portion of said charge at any given time of an open arc so as to heat the reagents to reaction temperture. The various vapors which form pass through the charge where they undergo additional reaction. The aluminum formed flows over the charge which is maintained at a temperature lower than reaction temperature, so as to obtain aluminum contaminated with no more than about 10 weight percent of aluminum carbide.

Abstract: A roll end support for a dispensing carton for sheet material and carton produced therefrom. A dispenser roll having sheet material wound on a hollow core is disposed within a carton and is supported by a pair of support assemblies located at opposite ends of the core. Each support assembly includes a first support member having a polygonal base corresponding substantially in size and shape to the polygonal ends of its receiving carton and further having a cylindrical body portion. A second support member has a cylindrical body portion rotatably received on the cylindrical body portion of the first support member. The two support members are locked to prevent axial separation and the second support member is inserted into the hollow core of the dispenser roll to permit rotary dispensing of the sheet material.
