  • X-ray tube having a variable focus which is self-adapted to the load
    Patent number: 5060254
    Abstract: Problems of thermal resistance both of the anode and of the cathode of an x-ray tube are solved by constructing a flat cathode which is set within a stair-step focusing device. It is shown that, depending on the shape of this device, the heat output on the anode is constant irrespective of the load on the x-ray tube.

  • Cathode for an X-ray tube and a tube including such a cathode
    Patent number: 5031200
    Abstract: The invention relates to X-ray tubes, and more particularly to cathodes for such tubes. The invention lies in the cathode, which includes an electron-emitting filament (26), being made in the form of a main body (10) of insulating material having metal electrodes (16 and 19) deposited thereon which are insulated from one another by the main body. The filament (26) and the electrodes (16 to 19) are connected to conductors (27, 21 to 23) which pass through the main body.
