Abstract: A casting powder useful in continuous casting of steel contains inorganic oxidic material meltable at the steel casting temperature and active carbon having a specific surface area according to BET of from 800 to 1200 square meters per gram.

Abstract: Tantalum (TaF.sub.5) or antimony pentafluoride (SbF.sub.5) is separated from a product mixture comprised of HF, isobutyryl fluoride and TaF.sub.5 or SbF.sub.5 by distillation below 760 mm of mercury.

Abstract: A process is described for the manufacture of aryl esters such as phenyl esters by liquid phase reaction of an aromatic compound such as benzene with molecular oxygen in the presence of a perfluorocarboxylic acid and carboxylic acid preferably having 5 or more carbon atoms over a catalyst composed essentially of a compound of palladium, an antimony compound and optionally a compound of at least one member selected from the group consisting of chromium, cobalt, nickel, manganese, iron and tin wherein the aromatic compound is added continuously to the reaction and water formed in the reaction is rapidly and continuously removed from the reaction mixture.

Abstract: A process for the production of isobutyryl fluoride by reacting isopropyl fluoride and carbon monoxide in the presence of anhydrous hydrofluoric acid is described.

Abstract: An aromatic isocyanate is formed directly from an aromatic hydrocarbon, nitric oxide and carbon monoxide by contacting a Group VII or Group VIII metal catalyst at a temperature between 350.degree. and 550.degree. C. with a feed stream of said reactants.

Abstract: A foundry binder which contains certain fulvenes and/or prepolymers thereof, and an acid catalyst.

Abstract: A vapor phase process for the direct oxidation of a methyl benzene to the corresponding aldehyde derivative; e.g., conversion of toluene to benzaldehyde, wherein said oxidation is effected in the presence of a catalyst system consisting essentially of uranium and molybdenum oxides in combination with an oxide of lead, tin, zirconium, cadmium, antimony or nickel.

Abstract: A method for the production of an axial roller bearing cage comprising applying pressure transverse to its longitudinal direction along the entire longitudinal extent of one end flange of a flat cage strip of plastically deformable material with two spaced end flanges connected by a plurality of crossbars to form pockets for receiving rollers and an apparatus for effecting the said method.

Abstract: Method for exhaustively alkylating the amine content of an imidazoline product prepared from a higher fatty acid and a dialkylene triamine wherein the protonated species formed in the course of the alkylation reaction are repeatedly neutralized, followed in each instance by reaction with an essentially equivalent amount of the alkylating agent based on the free amine present until the starting amine content of said product is predominantly converted to quaternary ammonium derivatives.

Abstract: A method for the preparation of N,N-dialkyl derivatives of mono- and diacyl hydrazines wherein the corresponding unsubstituted acid hydrazide is reductively alkylated with an aldehyde.
