  • Patent number: 7387280
    Abstract: In a switch including a main track and a branch track, wherein one rail of each track is each configured as a tongue rail and movable into abutment on the respective stock rail, at least one stock rail (1), in its region of abutment on the tongue rail (2), is designed to have a reduced rail head width as compared to the region located outside said region of abutment, wherein the rail head width, starting from the tip (3) of the tongue, decreases as far as to a point (4) at which the carrying wheel comes into lateral contact with the tongue rail (2) and increases in the region following thereupon, and that the tongue rail (2) is designed to be reinforced in cross section towards the stock rail (1) according to the reduction in the width of the stock rail head.

  • Patent number: 5148980
    Abstract: In a device for mounting in position guide rails (1), in which device the guide rail (1) is free of perforations and is seized by claws (3), which claws (3) are fixed in a mounting part, the mounting part has a mounting plate (2) extending in parallel relation to the longitudinal direction of the guide rail, noting that the claws (3) can be passed through perforations (16) in the mounting plate and can be braced against the mounting plate (2), in particular with the interposition of a spring (4), at the side, located opposite the guide rail (1), of the mounting plate (2).

  • Patent number: 5118991
    Abstract: In an electron beam generator where the heating current for the cathode is transformed by an insulating transformer 7 disposed on the high-voltage insulator 4 of the beam head, the primary winding of this insulating transformer 7 being connected to ground potential, and where a single-pole high-voltage connection 2 and a single-pole high-voltage cable 2 connect the beam head 3 to a high-voltage generator 1, the high-voltage cable 2, at its terminal ends, has a protective resistor 10 corresponding to the surge impedance of the high-voltage cable 2 in order to reduce the damages to insulating and component parts.

  • Patent number: 5117085
    Abstract: 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.

  • Patent number: 5095241
    Abstract: 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.

  • Patent number: 5089686
    Abstract: In the electron beam generator the cathode (3) the control electrode (4) and the anode (5) are provided with easily replaceable parts (12, 13, 14, 28, 29) so as to be able, by exchanging the parts, to optimize the electron beam generator in a simple manner for a selected power range within the working range of the electron beam gun.

  • Patent number: 4927102
    Abstract: 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.

  • Patent number: 4917339
    Abstract: In a reversing device for rails which are swivelable around a swivelling axis, or for movable frogs within the crossing area of a railway switch, the swivelable rails or, respectively, the movable frogs are supported in their position being in alignment with wing rails or, respectively, connecting rails or, respectively, being in contact with such rails by supporting ro)$

  • Patent number: 4061786
    Abstract: 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.

  • Patent number: 3961085
    Abstract: 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.
