Publication number: 20100243383Abstract: A clamping device with a housing, a spindle which is rotationally mounted in the housing, and an elastic clamping element, the clamping element being movable by application of a force out of a first position in which the spindle can be turned into a second position in which the spindle is clamped by the clamping element. The clamping element has an inner cylinder which surrounds the spindle to be clamped, an outer cylinder which is located coaxially to the inner cylinder, and a membrane which connects the inner cylinder to the outer cylinder. The clamping element is annular and roughly cup-shaped with an opening in the middle of the clamping element so that the inner cylinder surrounds the spindle to be clamped. The clamping element is shaped and arranged such that, by applying a force to the clamping element the curvature of the membrane can be changed.Type: ApplicationFiled: March 22, 2010Publication date: September 30, 2010Applicant: PEISELER GMBH & CO. KGInventors: Benedict KORISCHEM, Hans Hölter

Patent number: 6848609Abstract: In a method of making finned tubes as components of air-cooled systems or condensers, a sheet metal strip of aluminum is first shaped into a waved finned structure with plural fins in parallel relationship and arched ends for connecting the fins, thereby defining crests on opposite ends of the finned structure. A fluxing agent of cesium-aluminum tetrafluoride is applied in lines onto the crests on at least one of the ends of the finned structure. The finned structure is then placed upon a broad side of a flat steel tube coated with a zinc/aluminum alloy. The finned structure and the flat tube are subsequently joined in a brazing furnace in the presence of an inert gas at a temperature between 370° C. and 470° C. to produce a unitary structure which is then allowed to cool down at room temperature.Type: GrantFiled: December 16, 2003Date of Patent: February 1, 2005Assignee: GEA Energietechnik GmbHInventors: Benedict Korischem, Horia Dinulescu, Raimund Witte, Eckard Volkmer

Patent number: 6715667Abstract: In a method for joining a steel tube with an aluminum rib, a zinc-aluminum alloy layer, having an aluminum content of 0.5% by wt. to 20% by wt., is applied to the surface of the steel tube or the aluminum rib, and then a fluxing agent in the form of cesium-aluminum tetrafluoride is applied between the steel tube and the aluminum rib at room temperature before or during the mechanical contact of the aluminum rib with the steel tube. The steel tube provided with the aluminum rib is then heated to a soldering temperature of between 370° C. and 470° C. and subjected to room temperature to cool down.Type: GrantFiled: July 22, 2002Date of Patent: April 6, 2004Assignee: GEA Energietechnik GmbHInventors: Benedict Korischem, Horia Dinulescu, Raimund Witte, Eckard Volkmer

Patent number: 6474272Abstract: Apparatus for the condensation of steam, includes a substructure, a fan supported by the substructure and a plurality of self-supported tube bundles which are arranged in a roof-shaped manner in opposing relationship with respect to a vertical center longitudinal plane and mounted to the substructure above the fan, with each of the tube bundles having an upper tube plate and a lower tube plate. A steam distribution duct is fluidly connected to the upper ends of the tube bundles, whereas condensate collection pipes are fluidly connected to the lower ends of the tube bundles. The upper tube plates of opposite tube bundles so mutually support one another as to allow a limited pivotal movement of the tube bundles, and the condensate collection pipes are so positioned on the substructure as to be shiftable relative to the substructure in parallel relationship to the center longitudinal axis.Type: GrantFiled: April 10, 2001Date of Patent: November 5, 2002Assignee: GEA Energietechnik GmbHInventors: Heinz-Dieter Bensing, Benedict Korischem
