    摘要： A shaft seal containing magnetic liquid, for pump shafts or the like, consists of a permanent magnet which surrounds the shaft and is a distance away and one or more pole pieces connected to the said magnet. The pole piece, together with the shaft surface, forms an air gap in which the magnetic liquid is held by the magnetic field, so that a liquid sealing ring is produced. A volume of gas located between the magnetic liquid seal and the shaft channel to the medium prevents the magnetic liquid from coming into contact with the medium.

    摘要： Ceramic moldings, in particular those having geometrically complicated shapes, are produced by a process in which a ceramic powder is mixed with a molding additive and the mixture is injected into a mold. In order to improve the mechanical properties of the molding, a solution of a high molecular weight polymer in a solvent is used as the molding additive. The mixture is injected at a temperature below the boiling point of the solvent and under from 100 to 1,500 bar into a porous, gas-permeable mold which is at a temperature above the boiling point of the solvent, the injection pressure being maintained until gas no longer escapes from the molding material or the mold.
