  • METHOD AND PRESS FOR THE PRODUCTION OF MOLDING ELEMENTS
    Publication number: 20080067707
    Abstract: In a method for producing molding elements having a predetermined thickness profile, in which a filling tool of a filling device is filled with a molding material and the molding material is released in the direction of gravity from the filling tool into a pressing mold of a press, the molding material is held in the filling tool by means of suction, and its release into the pressing mold is effected by a reduction, particularly a deactivation, of the suction force.

  • Membranes based on silicic acid heteropolycondensates and a process for their production
    Patent number: 4505985
    Abstract: Membranes based on silicic acid heteropolycondensates are produced by hydrolytic polycondensation of at least one silicic acid derivative in the presence of water and, if appropriate, a condensation catalyst, the polycondensation being carried out at the surface of a support, which supports the resulting membrane. The reactants can be fed to the surface of the support via the gas phase or via one or more liquid phases.

  • Abrasive compositions
    Patent number: 4440745
    Abstract: Abrasive compositions comprising a porous, organo-modified silicic acid hropolycondensate as abrasive and one or more conventional components selected from the group of carriers, adjuvants and active substances such as pharmaceuticals, disinfectants, insecticides, bactericides, etc. The compositions are useful in medical and cosmetic applications, such as in the treatment of acne or as a tooth paste, and also in various technical and industrial fields, e.g., as a polishing or cleansing material.
