Abstract
279,861. Loewe, S., and Kunze, W. Oct. 28, 1926, [Convention date]. Vacuum tubes.-In a supersonic-heterodyne wireless receiver, a double-grid valve 3 is used in association with a triode valve 4 and the two sets of electrodes may be enclosed in a single envelope, as shown in Fig. 5. When the filaments: are connected in series, and the coupling resistance or condenser 8 is housed within the envelope, only six external connections are required. for the combined valve.
