ABSTRACT:
In an apparatus for mounting, within the glass neck of a cathode ray tube envelope, an electron gun assembly which includes the usual glass stem in the form of a disk with an exhaust tubulation extending centrally therefrom for eventual evacuation of the envelope, an upright support tube is provided with a central bore which is closed at its lower end and opened at the upper end for receiving the exhaust tubulation when the electron gun assembly is supported by such tube with the stem above the upper end of the support tube, and the support tube further has longitudinal passages therein spaced outwardly from the central bore and isolated from the latter, such longitudinal passages opening at ends thereof adjacent the upper end of the support tube. The cathode ray tube envelope is supported with its glass neck extending downwardly about the stem of the electron gun assembly carried by the support tube, and the glass neck is heated in the vicinity of the stem so as to fuse together the neck and stem, whereupon an inert gas under pressure is supplied to the longitudinal passages of the support tube and exits therefrom through the passage ends below the stem to act on the heated neck for severing the latter immediately below the fusing thereof to the stem without the danger of blowing dust into the cathode ray tube envelope through the exhaust tubulation upon the supplying of the inert gas.
