Definitions

  • 'I'he present invention relates to vacuum tube devices, and more specifically to electron discharge tubes having coaxially related tubular lead-in conductors for the electrode system thereof.
  • the present invention has for its object to eliminate drawbacks of the aforementioned kind.
  • 'I'he tubular conductors are, according to the 30 main feature of my invention, provided with a number of apertures circumferentially arranged thereon in radial relation to each other and in ⁇ (Cl. Z50-27.5)
  • the tubular conductors I and 2 may be chrome-iron pipes, for example.
  • each conductor of the coaxial system is provided with a number of apertures eircumferentially arranged in radial relation to each other in one geometric plane. These apertures are indicated l5 at l in the accompanying drawing.
  • a fluid vitreous sealing material poured onto the upper surface of either of the members 3, 4 and 5 for producing a vacuum seal between the several members of metal and ceramic material is allowed to iiow through these apertures so as to form a continual undivided glass coating 8 of uniform tensional properties, which will not give rise to any diiiiculties of the heretofore mentioned nature.
  • a vacuum tube comprising an envelope, an electrode arrangement therein, a coaxial conductor system having an inner and an outer tubular conductor electrically connected with said electrode arrangement, and means to aiiix said conductor system to said envelope comprising a disc of ceramic material in said inner conductor at right angles to the axis thereof, a first annular ceramic member in the space between said inner and said outer conductor, a second annular ceramic member arranged about said outer conductor and in one plane with said disc and said first annular member, a row of radial apertures in each of said tubular conductors located in a further plane parallel with and slightly above said first mentioned plane, and a layer of vitreous material on the upper surfaces of said disc and said annular members in the said further plane and extending through said apertures.
