Abstract: A protective base 20 for a color picture tube type of electron discharge tube having an evacuated envelope is formed in situ. At least one lead-in conductor 14' is sealed through the envelope, an insulative member 28 disposed around the lead-in conductor so that the insulative member contacts the outer surface of the envelope, and an electrically insulating material 20 is moulded about at least a portion of the insulative member 28, thereby compressibly retaining the insulative member in contact with the outer surface of said envelope. The base 20 may be of polysulphone whilst the member 28 is of silicone resin. Various configurations are shown for the member 28 (Figures 4 to 6). A silo 26 is provided to give a long leakage path between the high voltage electrode 14' and the other electrodes.

Abstract: A sealing fixture for aligning the sealing edges of a funnel and a panel of a kinescope during fritting is tilted so that a funnel placed in the fixture is gravity moved toward a corner of the fixture. All contact between the funnel and the fixture is made through rotatable referencing elements so that gravity accurately positions the funnel in the fixture.

Abstract: A cathode ray tube includes a faceplate panel with a plurality of electrode support studs distributed about and attached to the panel. A color selection electrode having a plurality of support springs is disposed within the panel. Each of the support springs comprises a strap-like element having a proximal end secured to the electrode and a distal end spaced from the electrode. A washer-like element is located between the panel and the distal end of at least one of the strap-like elements. The washer-like element has a frustoconically-shaped portion with an aperture therein for snugly receiving one of the studs. The base portion of the washer-like element is substantially flat and is permanently secured to the strap-like element near its distal end.

Abstract: A deflection adjustment device for a television deflection yoke and kinescope comprises a pair of magnetically permeable tabs adapted for linear movement along the kinescope minor axis. Means are provided for translating the rotary motion of a yoke adjustment machine into the desired linear tab travel. The tabs are moved in equal amounts, either toward or away from the yoke axis, to maintain the tabs equidistant from the yoke axis in order to correct coma errors.
