Abstract
Abstract The disclosure relates to a gas injected vacuum switch comprising a housing having an interior chamber, a conduit for evacuating the interior chamber, within the chamber an anode and a cathode spaced from the anode, and a detonator for injecting electrically conductive gas into the chamber between the anode and the cathode to provide a current path therebetween.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
A gas injected vacuum switch comprising; a housing having a generally cylindrical interior chamber; first conduit means operably connected to said chamber for evacuating said chamber; an anode disposed within said chamber; a cathode, spaced from said anode, disposed within said chamber; second conduit means for providing a passageway into said chamber; means for sealing said chamber from said second conduit means; and means for producing electrically conductive gaseous material, for breaching said seal, and for injecting said material through said second conduit means into said chamber to provide a conductive path for electric current between said anode and said cathode.
Claim 2
Dependent Claim
101 words
A gas injected vacuum switch comprising; a housing having a generally cylindrical interior chamber; first conduit means operably connected to said chamber for evacuating said chamber; an anode disposed within said chamber; a cathode, spaced from said anode, disposed within said chamber; second conduit means for providing a passageway into said chamber; means for sealing said chamber from said second conduit means; and means for producing electrically conductive gaseous material, for breaching said seal, and for injecting said material through said second conduit means into said chamber to provide a conductive path for electric current between said anode and said cathode.
Claim 3
Dependent Claim
38 words
The invention of claim 1 wherein said cylindrical chamber has a longitudinal axis therethrough, said first conduit means is cylindrical, having a longitudinal axis, and the longitudinal axes of said chamber and said first conduit means are aligned.
Claim 4
Dependent Claim
38 words
The invention of claim 1 wherein said cylindrical chamber has a longitudinal axis therethrough, said second conduit means is cylindrical, having a longitudinal axis, and the longitudinal axes of said chamber and said second conduit means are aligned.
Claim 5
Dependent Claim
25 words
The invention of claim 1 wherein at least one of said anode and cathode contains aperture means for providing passage of said gaseous material therethrough.
Claim 6
Dependent Claim
69 words
The invention of claim 4 wherein said chamber comprises a cylindrical wall and said anode and said cathode are each generally cylindrical, each having a wall and having a longitudinal axis axially aligned with said axis of said chamber, said anode and said cathode being smaller in diameter than said chamber so that said walls of said anode and cathode are spaced inwardly from said wall of said chamber.
Claim 7
Dependent Claim
18 words
The invention of claim 5 wherein said walls of said anode and said cathode contain said aperture means.
