  • COMPOSITE SUPPORT SYSTEMS USING PLASTICS IN COMBINATION WITH OTHER MATERIALS
    Publication number: 20100018143
    Abstract: The invention describes a load-bearing system which is composed of a plurality of components of different materials. At least one component that dissipates load here is composed of plastic. A frictional bond achieved via at least one bonding technique transmits the loads for the various components. The plastic can be transparent.

  • High-frequency generator with harmonic-tuned resonant circuits
    Patent number: 5602515
    Abstract: In order to improve the efficiency of a self-starting high-frequency generator, where for self-starting power is fed back from the anode circuit to the control grid of the grid-controlled electron tube used as amplifier element, the following measures are provided. An additional oscillating circuit (L.sub.A3, C.sub.A3) which is tuned to a multiple of the operating frequency (f.sub.1) is arranged in the anode circuit. An oscillating circuit (L.sub.G31, L.sub.G32, C.sub.G3) tuned to a multiple of the operating frequency (f.sub.1) is likewise arranged in the control-grid circuit. Components (L.sub.G31) belonging to the feedback circuit are at the same time components of the oscillating circuit arranged in the control-grid circuit.

  • Circuit for preventing retarding field oscillations in electron tubes, especially for a pulse-width modulation stage in transmitters
    Patent number: 4720683
    Abstract: A circuit for preventing retarding field oscillations in electron switching tubes, includes a feeding diode connected to the plate of the switching tube, and a power supply for generating the retarding field voltage, the power supply being connected in parallel with the switching tube through the feeding diode.

  • Electron tube, especially transmitting tube, with a device for eliminating interfering retarding-field effects
    Patent number: 4501990
    Abstract: Electron tube assemble having coaxial electrodes and grids, including a tube with given electrode trajectories and oscillation period, and interfering retarding-field effect elimination means disposed around the tube for generating a magnetic field having field lines running inside the tube substantially parallel to the electrodes and grids deflecting the trajectories of the electrons moving radially with respect to the anode during operation of the tube and substantially perpendicularly intersecting and elongating the trajectories of the electrons for increasing the oscillation period of the electrons and eliminating interfering retarding-field effects.
