Abstract
274,028. Ideal Radiotelefon & Apparatefabrik Ges. July 9, 1926, [Convention date]. Vacuum tubes.-Plug-carrying bases of thermionic valves are provided with four separate or independent projections k, Fig. 3, of hollow formation in which the plugs s are assembled so that the plugs do not contact with the inner walls of the projections k, as shown in Fig. 4, or only contact therewith at isolated points. The recesses e between the projections k extend nearly to the bulb, the surface leakage path being thus increased and the capacity-loss between the plugs decreased.
