Title: Flux feeding method and apparatus
IPC: B22D11/108
Filed: 1974-05-17
Abstract: A method and apparatus for feeding flux to the molds of a continuous-casting machine. The apparatus includes a portable carriage on which are mounted one or more gas-tight bins for containing powdered flux, and feeding devices (e.g. screw feeders) under the respective bins.

Title: Catalyst and method for producing the catalyst.
IPC: B01J23/80
Filed: 1981-03-27
Abstract: This invention relates to a catalyst and a method for producing said catalyst.

After filtration and drying, the product is calcined at 750 DEG -850 DEG C. until there is obtained a product having a 60-100 percent spinel structure. Zinc salt is introduced in the pores of the spinel, and the product thereby formed is heated up to at least the decomposition temperature for the zinc salt which is then converted to zinc oxide. Possible addition of zinc oxide in addition to that introduced into the pores of the spinel may be admixed mechanically.
