  • Asynchronous motor with features creating magnetic field disturbance
    Patent number: 8542800
    Abstract: A component for introducing disturbances into the magnetic field of an asynchronous motor by altering a reluctance of the motor is disclosed. An asynchronous motor is provided that includes a stator having a plurality of windings that is configured to generate a rotating magnetic field when a current is provided to the plurality of windings. The asynchronous motor also includes a rotor positioned within the stator configured to rotate relative thereto responsive to the rotating magnetic field and a component separate from the stator and the rotor that is positioned within the rotating magnetic field, with the component being configured to alter a magnetic reluctance of the rotor so as create a disturbance in the rotating magnetic field.

  • X-ray tube with improved vacuum processing
    Patent number: 8509385
    Abstract: In one embodiment, an X-ray tube includes an electron beam source including a primary cathode configured to emit an electron beam and an anode assembly including an anode configured to receive the electron beam and to emit X-rays when impacted by the electron beam. The X-ray tube also includes an enclosure, at least the primary cathode and the anode being disposed in the enclosure, and a secondary cathode disposed in the enclosure and configured to emit electrons to impact the anode for degassing the enclosure.
