Abstract

After a gas panel has been constructed, and prior to the filling operation of the panel, the panel is heated to purge the interior thereof of any contaminants in the panel. Upon the completion of the purging operation, and while in the bakeout stage, the panel is filled with an ionizable gas and the tubulation which is connected to the panel for allowing the purging operation, and the entry of the gas must be "tipped-off" to seal the tubulation.

Tip Off Heater Assembly for Gas Panel

After a gas panel has been constructed, and prior to the filling operation of the panel, the panel is heated to purge the interior thereof of any contaminants in the panel. Upon the completion of the purging operation, and while in the bakeout stage, the panel is filled with an ionizable gas and the tubulation which is connected to the panel for allowing the purging operation, and the entry of the gas must be "tipped-off" to seal the tubulation.

Existing tip-off heaters in automatic systems have to be constantly adjusted because of the sagging of the heater (tip-off) assembly, or because the panels themselves do not align to the tip-off heater. Additionally, some of the tip-off heater assemblies become askew due to handling and exert unnecessary pressure on the tubulation or filling tube of the gas panel during the bakeout, effecting tubulation breakage.

In the drawing, the floating tip-off heater assembly 10 has been developed to permit a through center-to-center alignment of the heater 18A towards a vacuum chuck holding device 20, which permits alignment of the tubulation 11 connected to the gas panel 12 to permit tipping-off the tubulation 11 and sealing it.

As illustrated, a port nut 13 is used to seal the tubulation or tube 11 to the vacuum chuck 20. A plurality of guide bushings 14 are threaded into the existing port nut 13 and spaced about the port nut, the bushings being held in place on the port nut 13 by jam nuts 15...
