Definitions

  • the basic idea of the invention consists with the consequence that far smaller dimenin using compounds, more especially hydrides of sions may be chosen for the anode and thus for such metals rather than the pulverulent metals.
  • the whole tube conjointly with a chance of using These are decomposed in outgassing during the metals that had heretofore been unserviceable pumping process while incidentally resulting in for the present purpose, under like -load conditions, such as nickel. It has been discovered that 75 highly reactive metallic powder in a state of extremely ne division.
  • the method 95 It may also be advantageous to use as the supwhich consists in coating the member with the port for the porous layer a sort of metal such as hydride of a gettering material, heating said nickel which is capable of alloyng itself with the member to remove the hydrogen from the rna ensuing porous metal such as zirconium, because terial and to obtain a porous metal coating capable this promotes the adhesiveness upon the subof absorbing large quantities of deleterious gases. 100
  • the method of improving the heat radiating Occasionally it may be advantageous, with aA qualities of anode electrodes in electron discharge view to promote the adhesiveness of the active tubes, which comprises coating the anode with metal upon the substratum, to roughen the latzirconium hydride. ter or to provide it with a porous coat consisting 5.
