Abstract: A device for producing sponge iron from iron oxide lumps consists of a reduction shaft in which a hot dust laden reducing gas is delivered. The gas is produced in a gas generator by means of partial oxidation of solid carbon carriers and passes into the lower end of the reduction zone via lateral reduction gas inlets. The iron oxide lumps are fed to the upper area of the reduction shaft and are radially fed as sponge iron to the lower end of said reduction shaft via delivery organs. The delivery organs are arranged in such a manner that the sponge iron is conveyed only radially outwardly.

Abstract: A process for preparing a homogeneous liquid mixture consisting essentially of a normally solid polyolefin rubber copolymer of at least two different monoolefinically unsaturated hydrocarbons of 2-8 carbon atoms or of at least two different monoolefinically unsaturated hydrocarbons of 2-8 carbon atoms and at least one copolymerizable unconjugated diene hydrocarbon of 6-16 carbon atoms and at least an equal amount by weight of an extending oil having a viscosity of 50-5000 centistokes and a specific gravity of 0.84 - 0.98, which comprises:A. adding the copolymer to said extending oil at a temperature of 80.degree. - 230.degree.C; andB. admixing the copolymer with the hot extending oil at an agitation speed of 1-500 cm/sec and a shear velocity of 0.5 - 100 sec.sup..sup.-1 for a period of time sufficient to form said homogeneous liquid mixture substantially free of particulate copolymer.
