Patent number: 8216342Abstract: A method for producing membranes which contain at least one solid layer on one side of a porous substrate by treating the side of the support, which is to be coated, with a synthetic solution that forms the solid layer. The inventive method is characterized in that the space located behind the side of the porous support, which is not to be coated, is filled with an inert fluid during the production of the solid layer on the porous support, “behind” being from the perspective of the support. The pressure and/or the temperature of the fluid is/are selected such that the synthetic solution is essentially prevented from entering in contact with the side of the porous support, which is not to be coated.Type: GrantFiled: January 13, 2005Date of Patent: July 10, 2012Assignee: BASF SEInventors: Stefan Bitterlich, Hartwig Voβ, Gunter Schuch, Armin Diefenbacher, Manfred Noack, Ronald Schäfer, Ingolf Voigt, Hannes Richter, Jürgen Caro

Patent number: 5954900Abstract: This process serves to form a long-time-vacuum-tight, high-strength, and corrosion-resistant joint, by means of a joining material, between a first body and a second body each made of sintered, polycrystalline alumina ceramic with a purity greater than 92 wt. % or of sapphire. The joining material is interposed in the form of a paste, a foil, or a slip between the first body and the second body. The joining material has been made from 1) an agglomerate-free, highly disperse, high-purity .alpha.-alumina powder with particles of as high a degree of calcination as possible and of a size not exceeding 100 nm (=10.sup.-7 m), 2) an anorganic oxidic powder of an auxiliary sintering agent with particles of approximately the same size as the particle size of the .alpha.-alumina powder, 3) an organic vehicle which is dissolved or suspended in an organic or aqueous solvant and in which the particles of the respective powder are distributed as evenly as possible.Type: GrantFiled: September 23, 1997Date of Patent: September 21, 1999Assignee: ENVEC Mess- und Regeltechnik GmbH + Co.Inventors: Frank Hegner, Elke Maria Schmidt, Andreas Rossberg, Barbel Voigtsberger, Ingolf Voigt, Henry Ludwig
