Abstract

998,486. Cathode-ray tubes. SOC. DES VERRERIES INDUSTRIELLES REUNIES DU LOING. April 30, 1962 [April 28, 1961], No. 16430/62. Heading H1D. In the manufacture of a cathode-ray tube a rigid band is placed in position over the area of the welding line between the screen and cone portions of the envelope before the evacuation step so that, on account of the swelling observed to occur in this region of the envelope during evacuation, a good contact is obtained between the envelope and the band. The band may be of metal and in two parts 6, 6a and with an inner material 7 having a relatively high softening point, e.g. cuprous chloride.
