Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 83 words
A method of operating a torch, comprising the steps of: electrolytically generating hydrogen and oxygen by passing an electric current in the form of pulses of a duration not greater than 50 microseconds between at least a pair of electrodes at least partly immersed in electrolytically conductive water and juxtaposed with one another in a tightly closed tank containing the water; feeding the hydrogen and oxygen thus produced to a torch nozzle to form a mixture; and igniting said mixture at said nozzle.
Claim 2
Independent Claim 83 words
A method of operating a torch, comprising the steps of: electrolytically generating hydrogen and oxygen by passing an electric current in the form of pulses of a duration not greater than 50 microseconds between at least a pair of electrodes at least partly immersed in electrolytically conductive water and juxtaposed with one another in a tightly closed tank containing the water; feeding the hydrogen and oxygen thus produced to a torch nozzle to form a mixture; and igniting said mixture at said nozzle.
Claim 3
Dependent Claim 31 words
The method according to claim 1, in which the pulse interval between adjacent pulses is not less than two times but not greater than thirty times longer than the pulse duration.
Claim 4
Dependent Claim 56 words
The method according to claim 1 in which said electrodes are constituted by a plurality of electrically conductive cylinders concentrically arranged in said tank and of successively increased diameters, said electric current in the form of pulses being applied between the innermost electrode and the outermost electrode with one or more intermediate electrodes forming bipolar electrodes.
Claim 5
Dependent Claim 21 words
The method according to claim 1, in which the innermost electrode is poled anodic and the outermost electrode is poled cathodic.
