  • High energy recording on an acetyl acetonate
    Patent number: 4118229
    Abstract: Method of recording visible data wherein a polymeric layer containing acetyl acetonate is disposed through an image pattern to a laser beam.
    Type: Grant
    Filed: September 24, 1976
    Date of Patent: October 3, 1978
    Assignee: U.S. Philips Corporation

  • X-ray rotating-anode tube with a magnetic bearing
    Patent number: 4081707
    Abstract: X-ray tubes with a magnetic bearing either have the disadvantage that the anode must be at earth potential, so that an asymmetric high-voltage supply is required or that -- in the case of a symmetric high voltage -- a relatively wide air gap is necessary which requires a high driving force and a bearing which has a certain amount of drawbacks. The invention provides an insulator between the anode which is at the high-voltage potential and the rotor which is at the earth potential, so that the air-gap between the rotor and stator can be relatively small and an effective magnetic bearing is possible.
    Type: Grant
    Filed: December 22, 1976
    Date of Patent: March 28, 1978
    Assignee: U.S. Philips Corporation
    Inventors: Walter Hartl, Harry Eggelsmann, Claus-Peter Hodum
  • Rotary-anode X-ray tube
    Patent number: 4024424
    Abstract: A rotary anode X-ray tube wherein the anode carries the high voltage during operation; to achieve shorter acceleration times of the rotor, an insulator is provided between the rotor and the anode disc so that only a minimum air gap is required between the rotor and the stator.
