Abstract
566,651. Electron oscillators. STANDARD TELEPHONES & CABLES, Ltd. (Western Electric Co., Inc.). March 28, 1942, No. 4166. [Class 39 (i)] To assemble in alignment electrodes such as those used in a velocity modulated electron discharge tube, the electrodes are carried by discs 18 on the opposite faces of which are sealed short lengths of glass tubing 24a, 24b ; the electrodes are then mounted by the aid of jigs 32, 33, Fig. 5, on a central rod 36 and the adjacent lengths of glass tubes are sealed together. The jigs are held in place by removable spring clips which when withdrawn allow removal of the jigs. The electrodes may have corrugations 40, Fig. 6, to allow expansion or contraction without straining the seal to the glass ; the central electrode may be in the form of a plain disc. In another form, a spacer formed of a number of blocks 44, Fig. 8, with extensions 45 is placed round the assembly rod 46 with the jig 43 to position the electrodes 42.
