Abstract
245,574. Pressland, C. Dec. 10, 1924. Vacuum tubes.-A combined valve-holder and filament resistance comprises a support adapted to be fixed on the inside of a panel by means of clamping devices engaging in holes in the panel, one of the clamping devices accommodating the resistance-controlling rod which projects through the panel, while the other accommodates a valve inspection window. As shown, a flanged sheetmetal bracket 1 carries a valve-holder 3 and a resistance 7 having a control rod 8 passing through a sleeve 9, which is clamped inside an aperture in the panel 12 by a nut 13; a window 15 is mounted in a sleeve 14, which is secured in an aperture in the panel, and to the bracket by a nut 16. The resistance comprises a wire 7 wound on an insulating core and a sliding contact 20 mounted on the rod 8. The bracket acts as a screen for the valve and leads, and is maintained at earth potential by a connection with the earthed terminal of the filament battery.
