An apparatus and method for shearing tubular billets, the billet being engaged within apertures in a fixed and a moveable shear blade, the end part of the stock to be sheared off being located in the moveable shear blade and adjacent part of the stock in the fixed shear blade. A mandrel comprising three relatively moveable parts is provided. The free end or location part of the mandrel is engaged in the part of the stock within the fixed shear blade and the mandrel has a location part externally...

Durable pellets of a uniform desired size and uniform dense particle packing are produced from a mixture of a liquid, and if desired, fusible and pyrolyzible hydrocarbons and a binder, with finely divided particles of carbon-reducible oxides or oxidic materials, carbon, and mixtures thereof, the particles being in sizes favorable to dense packing. Such a mixture is spread on a horizontal surface to form a layer of uniform desired thickness which is consolidated, by moving a vibrating face under ...

This disclosure relates to a process for the production of a ceramic mould wherein a film-forming polymer is coated onto a pattern of polyurethane foam prior to the application of a ceramic composition.

In the production of aluminum by thermally decomposing an alkylaluminum compound with the aid of suitable apparatus, a problem arises with the fouling of such apparatus by the adherence of aluminum particles. Such fouling is reduced by conducting the decomposition within a neutral liquid solvent which is non-reactive with the alkylaluminum compound and is at a high temperature well above the temperature at which the compound normally decomposes in the pure state. In a commercial operation heated...

A process for producing high BTU gas which comprises contacting an organic feed material, containing hydrogen and at least 10 weight percent oxygen,with steam in a reaction zone in the presence of an alkali metal catalyst at an elevated temperature and an elevated pressure of at least 50 psig. It is particularly preferred to carry out gasification of the organic material at a pressure above 300 psig. Particularly preferred catalysts are potassium compounds, most preferably potassium carbonate. P...

Production of amides by contacting a saturated hydrocarbon and/or unsaturated hydrocarbon with a nitrile and hydrogen fluoride with or without a reaction diluent such as sulfur dioxide, sulfolane and ammonium fluoride followed by hydrolysis to form the amides. The amides have utility as agricultural chemicals, for example, insecticides, herbicides, or fungicides.

The sugar concentration in a vegetable crop is increased by applying to the growing plants an effective sugar enhancing amount of biuret. The biuret is preferably applied directly to plant parts.

Hydrogen is produced by the oxidation of a petroleum fraction in the presence of a catalyst comprising a salt containing nickel or manganese dispersed on a basic inorganic support.

Production of polynucleotides by incubating one or more kinds of nucleoside diphosphate in the presence of one or more kinds of divalent cation with a cultured material of a strain of microorganism rich in extractable polynucleotide phosphorylase and poor in enzymes degrading nucleic acids and nucleoside diphosphates is described.

Increased yields of gasoline may be obtained by isomerizing-cracking a low octane paraffin stream and then alkylating the isobutane fraction therein with an olefin fraction recovered by thermally steam cracking the deisobutanized isomerized-cracked stream.
