Abstract

1453083 Assembling cathode-ray tubes RCA CORPORATION 31 Oct 1973 [31 Oct 1972] 50694/73 Heading H1D A method of assembly an electron gun mount 88 and the bulb of a cathode-ray tube comprises holding the bulb (not shown) and the gun mount 88 so that they are coaxial and with the mount outside the bulb, defining an orientation plane, such as a tangent 90 to two of the electron guns, parallel to the axis of the mount 88, measuring by means of sensors 79 the position of the orientation plane 90 relative to a reference plane 84, rotating the gun mount 88 until the measurement indicates the correct orientation and then moving the gun assembly 88 axially into the bulb to which it is then sealed. Fig. 4 (not shown) illustrates a similar arrangement for an in-line electron gun assembly. The apparatus for holding the bulb and moving the gun mount in to the bulb is described with reference to Figs. 1 to 3 (not shown).
