Abstract: The invention is to a roller unit for calenders, planishers or the like, comprising a flex-compensated roller having a roller shell which is hydraulically supported, for the compensation of sags, the roller assembly comprising a mating roller, whereby one of the rollers exhibits a surface engraving, characterized in that the flex-compensated roller is provided with the surface engraving; and in that the surface engraving or, respectively, its carrier is detachably arranged.

Abstract: Process for the manufacture of a propellant for base-bleed gas generators, thus for generators made of a gas-producing charge for the increase of range wherein a binder and one or more granular or powdery solid substances are used at least one of which is an oxidant, characterized thereby that the binder is a thermoplastically deformable elastomer, that solvents are added to said elastomer which is thoroughly mixed with the solid substance and that said elastomer is deposited thereon by removal of the solvent with the formation of a granulate.

Abstract: Process for the manufacture of insulated propellant sets for base-bleed gas generators, said propellant set consisting of a propellant containing one or more solid substances, at least one of which is an oxidant, and a binder being a thermoplastically deformable elastomer, characterized thereby that the propellant is introduced into an insulating envelope, which as an essential component contains a thermoplastically deformable elastomer suited for the binder, and is forced into the envelope at increased temperature.
