Abstract

822,556. Electron beam focusing apparatus. GENERAL ELECTRIC CO. Feb. 28, 1956 [March 2, 1955], No. 6181/56. Class 39(1). An electron gun includes a plurality of beam controlling members 13, 15, 17, Fig. 1, supported in spaced alignment by insulating members, e.g. glass rods 19, 21 to which they are connected by straps 23, 25, 27, 29 fixed to the controlling members and having terminal portions with undercut recesses embedded in the insulating members. As shown in Fig. 1 the end portion 44 is formed by a script E cut-out to receive molten glass during assembly. In alternative embodiments, Figs. 3, 4 the end portions are formed respectively as C- shaped cut-outs or by a pair of arcuate recesses 41, 43 separated by a bulbous projection 45.
