Description

Schaltung für Elektronenröhren zur Abnahme einer negativen Gittervorspannung Zusatz zum Patent 574 924 Im Hauptpatent wird vorgeschlagen, zur Abnahme einer negativen Gittervorsparn@ nung in die negative Z,deitung der Stromquelle zu den Kathoden eine Entladungsröhre mit bei wechselnder Belastung praktisch konstantem Spannungsabfall zu schalten. An der Entladungsstrecke wird dann die Gittervorspannung abgenommen.Circuit for electron tubes to decrease a negative grid bias Addition to patent 574 924 In the main patent it is proposed to take a negative Grid precaution in the negative Z, line of the power source to the cathode Discharge tube with a practically constant voltage drop when the load changes to switch. The grid bias is then removed at the discharge path.

Die vorliegende Erfindung schlägt vor, in die negative Zuleitung an Stelle der Entladungsröhre einen oder mehrere in Serie geschaltete Kontaktwiderst:äride zu schalten. Die Kontaktwiderstände sind ebenso wie Glimmentladungsröhren Widerstände, .welche dem Ohmschen Gesetz nicht folgen, sondern bei denen zwischen bestimmten Grenzen der Widerstand dadurch wird, daß der Spannungsabfall auch bei wechselndem Stromdurchgang konstant bleibt. Diese Bedingung wird z. B. von Widerständen erfüllt, die sonst in der Technik für die Wechselstromgleirhrichtung benutzt werden, also Gleichrichterzelten bzw.,andere Detektoren o. dgl. Die Schaltung wird im übrigen in gleicher Weise wie bei der Anordnung des Hauptpatents getroffen. Gegenüber Entladungsstrecken bietet die Verwendung derartiger Widerstände Vorteile. Diese Widerstände .sind klein und unterliegen praktisch keinem Verbrauch. Außerdem können die Spannungen leichter dosiert werden. Für gewisse Zwecke ist es nämlich wünschenswert, genau vorausbestimmte Spannungen zur Verfügung zu haben. Kontaktwiderstände lassen sich mit ganz geringem Spannungsabfall von einigen Zehntel Volt herstellen, und man kann eine beliebige Zahl in Reihe schalten, so daß praktisch jede nur gewünschte Spannung bzw. Teilspannung zur Verfügung steht.The present invention suggests in the negative lead Place one or more series-connected contact resistors on the discharge tube: arid to switch. The contact resistors, like glow discharge tubes, are resistors, .which do not follow Ohm's law, but rather those between certain ones Limits the resistance is that the voltage drop even with changing Current continuity remains constant. This condition is z. B. filled with resistances, which are otherwise used in technology for the alternating current sliding direction, that is Rectifier tents or other detectors or the like. The circuit is otherwise taken in the same way as in the arrangement of the main patent. Compared to discharge lines the use of such resistors offers advantages. These resistances are small and are practically not subject to consumption. Also, the tension can be lighter be dosed. Indeed, for certain purposes it is desirable to have precisely predetermined ones Having voltages available. Contact resistances can be reduced with very little Make a voltage drop of a few tenths of a volt, and you can do any Connect number in series, so that practically every desired voltage or partial voltage is available.
