Definitions

  • the invention relates to sealing-in wires and especially sealing-in wires for discharge tubes.
  • An object of the invention is to provide a sealing-in'wire that will not have the high losses of magnetic material when used with short waves and on the other hand will have an expansion i coefficient suitable for sealing with the glass casing or the glass utilized as vacuum-tight sealing mate- 'iial around the wire with casings of other mate-
  • Figure 1 is a cross-section through the press of a discharge tube illustrating the preferred embodiment of the invention.
  • Fig. 2 is an elevation with parts in cross-section of a press of a discharge tube illustrating another 2@ modification of the invention.
  • the sealing-in wires for discharge tubes are usually made of certain materials, such as, for instance, alloys of iron or chromium, which are magnetic and which cannot be used, therefore, in
  • non-magnetic materials such as copper, which have been proposed for the purpose just men- 39 tioned have the disadvantage that their expansion coefficients differ too much from the expansion coeilicient of glass, so that if sealing-in leads in the form of wires or rods made of such a material are used, diiculties will be encountered when the 35 seals are made, while afterwards the seals may start to leak.
  • the present invention covers an alloy whose expansion coeicient is about equal to the expansion coefficients of the ordinary commercial grades 40 of glass, while on the other hand the alloy is practically non-magnetic.
  • .erjsealing-in wire for short-Wave discharge tubes is made of a material obtained by alloying iron or nickel either with tantalum, or with columbium 45 (also called niobium) or with tantalum and columbium, the iron or nickel content, or the content of iro'n and nickel in combination, being not higher than It has been found that the expansion of an alloy of this kind is such that the 50 alloy is a very suitable material to be sealed in by fusing in ordinary commercial grades of glass.
  • the alloy should contain a smaller or larger amount of nickel or iron, depending on the grade of glass. This content of iron or nickel should 55 not exceed 30% in order to obtain a material hav- (Ul. 25d-27.5)
  • the sealed-in lead should be called uponcto carry, in addition to a high-'frequency currenta 25 strong current of normal frequency 50 or 60 cycles say, it would be advisable to use a lead in the form of a tube made of an alloy covered by this invenf tion into which has been shoved a core of copper.
  • a lead-arrangement is repre- 30 sented in Fig. 1 on the drawing.
  • the tube made of non-magnetic alloy described in this specication is designated by l, and the copper core by 2. Air-tight joints between these two parts can be made in any suitable manner.
  • this copper core offers the advantage that a highly conductive lead is obtained, a point of great importance if the lead must carry heavy currents, While the tube-shaped sheath of the lead, which is made of an alloy covered by this 40 invention, is very well suitable for sealing-in purposes insofar as the expansive properties of the material are concerned.
  • a sealing-in lead for electric discharge Vessels consists of a tube-shaped outer part into which has been shoved with some clearance a rod-shaped or tubeshaped core, whereupon the clearance space between core and sheath has been closed by soldering the ends of the latter to the core.
