Definitions

  • This invention relates to a window made of metal or similar material provided in ametal wall. Such windows are used in'some discharge tubes, in which they serve for the passage of rays, for example, X-rays or cathode rays. 1
  • The'present invention has for its purpose to avoid these diiiiculties and concerns a metal or similar window in a metal wall, which window is fixedby fusing a binding agent consisting of a vitreous material which preferably surrounds the rim of the window.
  • a metal ring or locking-piece covering the rimof the window, a layer of the vitreous binding agent being interposed between such ring or locking-piece and the window.
  • The, provisionof such a locking piece renders the joint more rigid and afiords a certain protection at the same time.
  • the material of which these windows are made may be capable per se of being'fixed to the metal of the wall. If, however, the thickness of the windows is extremely small, sealing the window by fusing or welding its edge to the metal wall damages the window on, account of the heat employed. This difllculty is avoided-by thepresent invention and the risk of overheating the window may be further minimized by keeping the window in contact with a protective body, for example of graphite, during the mounting process whereby the temperature of the window isprevented from rising'unduly.
  • a protective body for example of graphite
  • the metal wall and the locking piece consists of a chrome iron alloy.
  • the bindingagent may also consist of or similar mixtures.
  • A- metal portion l constituting, for example, the wall or" a discharge tube for -X-rays or cathode rays, is provided with an aperture 2 which is shut off by a thin window 3 consistingior example, of.
  • L 1 A metal wallhaving an aperture, the wall at the edge of said aperture having'a peripheral recess, athin non-vitreous disc extending into said recess so as. to form a window, a fused vitreous;
  • binding agent enclosing the peripheral edge of said none'vitreous window, and a metal ringin the recess, said binding agent adhering to the bottom and side walls of said recess and to the metal ring.
  • a metal wall having an aperture, the wall at the edge of said aperture having aperipheral recess, a metallic window closing said aperture, a
  • Ari electric discharge tube for'emitting rays having a metal wall portion showing an aperture; a non-vitreous'window overlying said aperture of said wall portion and permitting the passage of the rays, the wall at the edge of said aperture being formed with a recess, a metal piece disposed insaid recess and spaced from the walls thereof,
