Patent number: 6237209Abstract: The invention features utilization of a duplicate form for creating a conformal cavity which equally mates with an original form having the same shape as the duplicate form. The duplicate form is situated in the wall from the inside of the wall, elastomer is cured onto the outside of wall and around the duplicate form, the duplicate form is removed, and the original form is situated in place of the duplicate form. The shape of the hole in the wall is not in strict conformity with the shape of the duplicate form and the original form, but rather is characterized by a small aberration which leaves a space when either the duplicate form or the original form is situated in the hole. This small aberration, together with the elastomeric quality of the cured material, permits ingressive venting during removal of the duplicate form and egressive venting during insertion of the original form. In typical inventive practice, the manipulative steps are performed from the inside of the wall.Type: GrantFiled: April 19, 1999Date of Patent: May 29, 2001Assignee: The United States of America as represented by the Secretary of the NavyInventor: Edward A. Leibolt

Patent number: 6170138Abstract: A capacitor is described, in particular a vacuum capacitor, comprising two electrodes (1, 1′), at least one insulator (5), and means for fastening (4, 4′). A process is proposed according to which the two electrodes (1, 1′) are each produced as one piece of an electrode material through a cold-flow extrusion process. The electrodes so produced are distinguished by a high surface quality. The result of this, in the capacitors produced from such electrodes, is high quality-factors, low temperature coefficients, a high current-carrying capacity, and an excellent dielectric strength, as well as a compact structure with a simultaneous reduction in the number of components required. Capacitors of this type, in particular vacuum capacitors, find application in HF technology for fixed and variable capacitance values.Type: GrantFiled: March 6, 1998Date of Patent: January 9, 2001Assignee: Comet Technik AGInventors: J.

Patent number: 6122814Abstract: A process for manufacturing a ring that has at least one cylindrical end section that ends in a chamfer is disclosed. The process entails providing a flat-shaped article which is formed of a material capable of being deep-drawn. The flat-shaped article is stamped to provide indentations which correspond to the chamfer in the finished product. The flat-shaped article is then punched out to form a preform. The preform is then deep drawn, converting the preform into the shape of the ring. In the step of deep drawing the preform, the indentations form a chamfered section on the ring.Type: GrantFiled: December 11, 1998Date of Patent: September 26, 2000Assignee: Firma Carl FreudenbergInventors: Helmet Pennig, Wolfgang Nickl, Wilhelm Dieter

Patent number: 6098262Abstract: A process for manufacturing a hollow body made of two mutually welded together metal bars which are flatly disposed on one another. Within an internal high-pressure forming tool in a closed position, the metal bars are widened by introducing a pressure fluid under a high pressure into the parting line existing between the metal bars, until they are placed on the die sinking of the forming tool defining the final contour while forming the hollow body. The metal bar composite is trimmed by a cutting operation, and the pressure fluid inlet area of the metal bar composite is cut off after the widening has taken place. In order to reliably manufacture a flangeless hollow body in a simple manner from two metal bars, the metal bars are seam-welded before entering into the forming tool, and the resulting metal bar composite is then trimmed by a beam welding process in the weld seam.Type: GrantFiled: September 28, 1998Date of Patent: August 8, 2000Assignee: DaimlerChrysler AGInventors: Volker Thoms, Andreas Poellmann
