Patent number: 5117085Abstract: The cathode holder 4 has two terminals 8, 9 which are rigidly connected to one another and together form a flange 20 which by means of a pressure bearing with spheres 27, 28 made of a ceramic material is supported in a carrier flange 3 connected to the control electrode 5. The spheres 27, 28 rest in rolling paths aligned in radial direction to the optical axis 14 and provide a centering of the cathode 7 with respect to the control electrode 6 which is independent of expansions.Type: GrantFiled: September 10, 1990Date of Patent: May 26, 1992Assignee: PTR Praezisionstechnik GmbHInventors: Dieter Fritz, Helmut Spruck

Patent number: 5095241Abstract: In the electron beam generator cooling is provided by the electrical conductors of the incandescent cathode and control electrode which are configured as heat bridges and connected to cooling plates in the interior of the high-voltage insulator which in turn are connected in a heat-conducting manner to a pot-shaped cooling body. The cooling body, configured as part of a capsule for accommodating circuitry for the control of the electron beam generator, is surrounded by a heat exchanger which is connected to a cooling circuit and is at ground potential, and is insulated from the cooling body by a wall of the high-voltage insulator.Type: GrantFiled: September 10, 1990Date of Patent: March 10, 1992Assignee: PTR Prazisionstechnik GmbHInventors: Dieter Fritz, Wolfgang Schwarz

Patent number: 4927102Abstract: In a reversing device for movable parts of a railway switch within the deflection area of a railway switch, in particular tongue rails, monorail deflection device or movable stock rails, in which device the movable rails can be caused to contact rigid switch parts, the movable rails are supported in their contacting position by supporting rods extending in the longitudinal direction of the rail the supporting rods are slideably guided on the sleepers or, respectively, base plates in the longitudinal direction of the rails. In this case, the supporting rods are designed as adjusting members for the reversing operation and comprise thrust supports cooperating with thrust supports of the movable rails for shifting the rails. At least one of the mutually cooperating surfaces of the thrust supports of rail and/or of supporting rod is formed of a wedge surface passing over into a supporting surface extending in an essentially parallel relation to the longitudinal direction of the supporting rod.Type: GrantFiled: November 7, 1988Date of Patent: May 22, 1990Assignee: Voest-Alpine Maschinenbau Gesellschaft m.b.H.Inventors: Gerald Durchschlag, Alfred Lang, Franz Rotter, Dieter Fritz, Heinz Kopilovitsch

Patent number: 4061786Abstract: Dyed edible food casings, e.g., sausage casings, are produced by applying an edible dye to an edible carrier therefor, fixing the dye on the carrier by use of a protein, and admixing the carrier with an edible casing material to form an extrudable composition. That composition is then used for production of the casing by extrusion. The dye can be a water soluble dye, a fat soluble but water insoluble dye, or a water insoluble, alkali soluble dye.Type: GrantFiled: February 18, 1976Date of Patent: December 6, 1977Assignee: Naturin-Werk Becker & Co.Inventors: Bruno Winkler, Bernd Mangei, Dieter Fritz

Patent number: 3961085Abstract: A dyed edible food casing is produced by effecting dyeing prior to filling of the casing. The edible dyestuff is incorporated, as such or in encapsulated form, with the raw composition awaiting extrusion. Instead, the extruded tube is itself dyed. Water-resistance is imparted to the dyestuff by admixing a cross-linkable substance.Type: GrantFiled: February 11, 1975Date of Patent: June 1, 1976Inventors: Bruno Winkler, Dieter Fritz
