Patents by Inventor Hartmut Ganzle

Hartmut Ganzle has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Temperature compensated electron gun system
    Patent number: 4631442
    Abstract: An electron-gun system is described in which the segments of the particularly long electrode neighboring the other electrodes are made of a material having a temperature expansion coefficient differing from that of the other electrodes.
    Type: Grant
    Filed: September 21, 1984
    Date of Patent: December 23, 1986
    Assignee: International Standard Electric Corporation
    Inventors: Hans Reule, Hartmut Ganzle
  • Electron-beam forming system for multi-beam cathode-ray tubes
    Patent number: 4492894
    Abstract: The electrodes of an electron-gun system of a color-picture tube are heated less as their distance from the cathode of the system increases. The electrode materials are so chosen with respect to their coefficients of expansion that no mechanical stresses are caused in the system structure despite the different temperatures.

  • Method of mounting the support for a fast warm-up cathode
    Patent number: 4263701
    Abstract: The cathode support of an indirectly heated cathode for picture tubes is commonly mounted in a ceramic disk by cold riveting. With sheet thicknesses below 0.1 mm, the support cracks during riveting. According to the invention, that portion of the support which projects beyond the ceramic disk is first rolled over by wobble-riveting, after which the support is braced by hot-pressing. This insures that the cathode support is securely held in place and prevents cracking.
