    Abstract: 1420692 Magnetic recording tape BADISCHE ANILIN- & SODA-FABRIK AG 27 April 1973 [28 April 1972] 20074/73 Heading B2E A thermostable rigid base plated with a firmly adhering film of ferromagnetic metallic material containing cobalt has applied thereto a layer from a solution of at least one film-forming organic coating resin in a volatile solvent, the layer in dried and unbaked condition being not more than 3000A thick, and drying and baking being effected at 200-300‹C for 1-15 hours. Specified resins are polycarbonates, polyurethanes, acrylic polymers, polyglycidal ethers and esters cured with polyamines and polyaminoamides and phenol-amine resins. The ferromagnetic metal may be Co-P, Co-B, Co- Ni, Co-Fe-Ni alloys. Ketones, ethers and hydrocarbons are typical volatile solvents.

    Abstract: A process for the preparation of zeolites of the ZSM-5 structural type from a mixture of SiO2 and Al(OH)3 by hydrothermal crystallization in an aqueous amine solution, in the absence of alkali, at from 100 DEG to 200 DEG C., wherein the crystallization is carried out in the presence of a triamine, tetraamine and/or higher amine and the reaction mixture is formulated to have an SiO2/Al2O3 molar ratio defined by an equation which involves the chain length and number of amine groups of the amine employed, as well as to have certain molar ratios of H2O/amine and amine/Al2O3, and the use of these zeolites as catalysts for the conversion of alcohols and/or dialkyl ethers to olefins and/or aromatics.

    Abstract: Amorphous metal/magnesium silicates of the general formula MxMgy(SiO2).nH2O. where M is a divalent, reducible metal atom from the group consisting of Cu, FeII, Co and Ni, x and y are numbers which together can add up to a value of 1.5 and n after drying, expressed in % by weight, ranges from 0 to 80 are prepared by subjecting a freshly precipitated magnesium silicate to an ion exchange, washing the product and then neutralizing it with an alkali and are used in catalytic reactions after the reducible metal in the metal/magnesium silicates has been converted into the metallic state with a reducing gas.
