Abstract

216,585. Seymour, C., Hughes, H. G., and Goldup, T. E. March 1, 1923. Vacuum tubes. - An electrode such as a cylindrical anode A has extensions or supports E of unequal length to facilitate the passage into and engagement with tubes D or supports of equal length attached to or carried by the cap C of a valve. Instead of tubes D rods provided with hollow cups may be employed. The filament leads may be secured to projections N on an insulator P as described in Specification 204,237, and a grid-filament structure as described in Specification 176,898 may be secured in the cap by bent-over portions or springs L.
