Patent ID: 8765050

Claim:
A portable fluid injector to metal enclosure comprising: a frame; a miniature cutting torch mounted to the frame, the miniature cutting torch comprising a first cylinder of oxygen and a second cylinder of a gaseous, combustible aliphatic hydrocarbon; a third cylinder of an injection fluid mounted to the frame; the miniature cutting torch further comprising: a pivot arm rotationally connected with respect to the frame, the pivot arm comprising a rotating end and a nozzle end; a nozzle supplied with oxygen from the first cylinder and with the gaseous combustible aliphatic hydrocarbon from the second cylinder, the nozzle connected to the nozzle end of the pivot arm; an igniter; and a guide tube extending from the pivot arm to a position below the nozzle such that the guide tube can progress into a hole cut below the nozzle; a limit switch that automatically turns off the miniature cutting torch when the limit switch is engaged by rotation of the pivot arm to the limit switch; a magnet on the frame so as to provide sufficient magnetic force to hold the portable gaseous injector on a magnetic metal; valves controlling release of oxygen from the first cylinder, the gaseous, combustible aliphatic hydrogen from the second cylinder; and the injection fluid from the third cylinder; and a computer radio-frequency controller operably connected to the valves and the igniter.
