Definitions

  • the tubular metal anode envelope l has positioned within it the grid-2, and the cathode 3.
  • the electrodes 4, 5, and 8, in the form of concentric tubes, are supported in spaced rela- 40 tion by concentric ceramic rings 1, i, and 9, which, with the ceramic plug l in the base of the tubular conductor 6, form a flat or disc-like inset plug corresponding to a press in a conventional tube.
  • the leads are extended perpendicu- 45 lar from the closure and supporting member into the envelope, and form in the space outside the envelope a co-axial tubular system which is free from radio frequency radiations.
  • the electrodes are supported within the metal envelope solely 50 by the leads.
  • a cathode such as shown in Figure 2, comprising so-called twin or double prism lamentary cathodes i5 and i6 each consisting of three or more spaced parallel current-carrying filaments connected together at their ends so that they lie in the edges of an imaginary prism.
  • the filaments which traverse a pair oi prisms are all interconnected at the' bottom as shown and supported solely bythe lead conductors.
  • no central rod is required for supporting the cathode, thereby eliminating the possibility of such a rod forming an oscillatory system with the electron emitting laments of the cathode.
  • a tube formed by riveting the edges of the molybdenum sheet together in this way may then be smply fused to the ceramic insulator, provided the molybdenum tube has a suiliciently thin wall.
  • An electron discharge tube for use at high frequencies comprising a tubular metal envelope open at one end, member of ceramic material closing the open end of said envelope, a plurality of concentric tubular leads imbedded in said member, and electrodes supported solely by said leads within said envelo 2.
  • An electron discharge tube for use at high frequencies comprising a tubular metal envelope open at one end, a member o1' ceramic material closing the open end oi said envelope, a plurality oi concentric tubular lead conductors imbedded in said member and supported in spaced relation with each other and with the envelope by said press. and electrodes supported on said lead conductors within the envelope.
  • An electron discharge tube for use at high frequencies and comprising a'tubular metal envelope open at one end, an inset plug of ceramic material closing the open end of said envelope, a plurality of concentric tubular lead conductors imbedded in said inset plug, and electrodesincluding a cathode comprising a plurality o! parallel maments arranged to traverse a pair of prisms supported by said lead conductors within the envelope.
  • Anl electron discharge tube for use at high frequencies/ and comprising a tubular envelope open at onev end, a :dat inset plug o! ceramic materia] closing the open end of the envelope.
