PATENT-ANSPRÜCHE : 1. Elektrische Entladungsröhre mit einer indirekt geheizten Kathode, einem oder mehreren Gittern und wenigstens einer Anode, wobei der Abstand von den Gittern und der Anode, zur Kathode EMI2.1 zwischen der Kathode und den übrigen Elektroden am grössten ist, eine nur aus einem oder mehreren Stäben bestehende Elektrode angeordnet ist. PATENT CLAIMS: 1. Electrical discharge tube with an indirectly heated cathode, one or more grids and at least one anode, the distance from the grids and the anode to the cathode EMI2.1 is the largest between the cathode and the other electrodes, an electrode consisting of only one or more rods is arranged. 2. Elektrische Entladungsröhre nach Anspruch 1, dadurch gekennzeichnet, dass die Kathode von im wesentlichen runder Gestalt von einer oder mehreren weiteren Elektroden von ovalem oder rechteckigem Querschnitt umgeben ist und dass zwischen der Kathode und der diese unmittelbar umgebenden Elektrode ein oder mehrere Stäbe an jenen Stellen angeordnet sind, wo der Abstand der Kathode von der nächsten Elektrode am grössten ist, - 3. Elektrische Entladungsrohre nach Anspruch l oder 2, dadurch gekennzeichnet, dass die Stäbe während des Betriebes auf einem positiven Potential gehalten werden. EMI2.2 2. Electrical discharge tube according to claim 1, characterized in that the cathode of substantially round shape is surrounded by one or more further electrodes of oval or rectangular cross-section and that between the cathode and the electrode immediately surrounding it, one or more rods at those points are arranged where the distance between the cathode and the next electrode is greatest, 3. Electrical discharge tubes according to claim l or 2, characterized in that the rods are held at a positive potential during operation. EMI2.2
