Abstract
Abstract Sealed electrode mounting, in a spark discharge chamber, comprising a plane cathode and, parallel thereto, two latticeshaped electrodes constituting an auxiliary electrode and anode enclosed in a space forming the spark discharge chamber, the electrodes being along its entire circumference in electrically conductive connection with an electrically conductive material surrounding the periphery of the respective electrodes and extending through sealing means, which run along said electrical material, and out from the spark discharge chamber.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
In a sealed electrode mounting arrangement, in a spark discharge chamber, comprising a plane cathode 1 and, parallel thereto, two lattice-shaped electrodes 2, 3 constituting, respectively, an auxiliary electrode 2 and an anode 3 enclosed in a space forming the spark discharge chamber, the improvement wherein each of the electrodes along its entire circumference is in electrically conductive connection with an electrically conductive material 5, 6, 14, 15 surrounding the periphery of the respective electrodes and extending through sealing means, which run along the electrical material, and out from the spark discharge chamber thus placing the edges of the electrodes outside the spark chamber, and wherein the lattice-shaped electrodes are electrically insulated from one another by means of an annular spacer 4 arranged between them adjacent their peripheries, said spacer being coated with a metallic layer 5, 6, 14, 15 on plane opposing surfaces, said metallic layers comprising said electrically conductive material.
Claim 2
Dependent Claim
152 words

Claim 3
Dependent Claim
47 words
Device according to claim 1, in which the sealing means are arranged so as to provide a seal both against a disc constituting the roof of the spark discharge chamber and against an annular element constituting at least part of the bottom of the spark discharge chamber.
Claim 4
Dependent Claim
18 words
Device according to claim 1 in which the cathode and the electrodes are arranged on annular carrier elements.
Claim 5
Dependent Claim
22 words
Device according to claim 1 in which the sealing means consist of sealing strips arranged along the carrier elements and the spacer.
Claim 6
Dependent Claim
48 words
Device according to claim 3, in which on the carrier element carrying the cathode, there is a gastight foil on the plane confining surface remote from the cathode, the space between the cathode and said foil communicating via channels in the carrier element with the spark discharge chamber.
