Definitions

  • An object of the invention is the provision of a simple construction of a mount for the electrodes and the resonator for such devices.
  • an ultra high-frequency electron discharge device comprises a resonator arranged so that its axis is parallel to the major axis of the bulb and mounted upon a metal platform secured to a plurality of pins fused into a dished glass base onto which the bulb is sealed.
  • Figure 1 is a perspective view of the assembled resonator tube and its associated socket
  • Figure 2 is a vertical section through the centre of assembly and Divided and this application-August 10, 1948, Serial No. 43,382.
  • the triangular plate 12 also has cut in it three slots 21' to enable it to take up any strains which may be caused by unequal expansion of the glass and copper.
  • the anode 8,the collector plate 24, the grid 28 and the cathode 29 are mounted upon rods I3 which pass through the mica insulators i4 and I5 and through mica spacing plates Hi. The remaining pins H in the base are'used for connections to the electrodes.
  • the hole 5, Fig. 2 provides communication between the resonator and the glass tube l! which is sealed into the bulb l0 adjacent the hole 5; Conductors 18 for extracting energy from the resonator extend through the tube I1 and are sealed thereto at l9. v I
  • the valve When the valve is plugged into its socket 20, the three pins H which support the triangular platform or plate l2 engage in holes drilled in a substantial metal spider 2
  • the socket 20 is provided with a central hole 33 having a key- Way 34 into which the protruding metal spigot containing the sealing off tube of the glass bulb l0 extends; This spigot has a key which engages with the key-way 34 so as to ensure that the pins H make contact with the, proper terminals 22 of the socket.
  • Figure 3 is a plan of the base at a'section taken on the line 33 of Figure 2.
  • Figures 1 and 2 show how the resonator and its associated electrodes are mounted so that its axis is parallel to the major axis of the enclosing bulb, on a base of the kind comprising a dished glass member 9, the peripheral lip of the member 9 is fused to a lip on the lower end of the enclosing glass bulb I0.
  • Contact pins ll aresealed directly into the dished member 9.
  • the inner conductor ofthe resonator is made up of two copper rods 30 and. 3
  • small ends of the rods support an assembly of fins 32 which defines the slot through which the electron stream is fired.
  • the outer conductor 35 is fixed at both ends to the mushroom heads of therods.
  • the outer conductor of the resonator may be built up from three or more curved sections of suitable shape.
  • An. ultra high frequency electron discharge tube comprising. an elongated envelope'having a glass base at one'end thereof, a plurality of pins fused throughsaid base, a metal platform secured to said pins, a resonator having a center conductor structure mounted upon said metal platform, electrodes disposed adjacent'said res onator in said envelope, insulated means carried by said. centerconductor structure for supporting said electrodes adjacent said resonator, and
