Description

Das Hauptpatent 813 576 betrifft Kippschaltungen unter Verwendung von Raumladegitterröhren, bei denen die Anode bzw. ein mit der :Anode galvanisch verbundenes Gitter und das Steuergitter der Kippröhre über einen Transformator fest rückgekoppelt sind. Hierbei ist das zwischen Steuergitter und Kathode der Kippröhre liegende Raumladegitter über eine Impedanz, vorzugsweise eine Induktivität, mit dem Steuergitter galvanisch verbunden.The main patent 813 576 relates to flip-flops using space charge grid tubes, in which the anode or a grid galvanically connected to the anode and the control grid of the tilt tube are permanently fed back via a transformer. Here, the space charge grid located between the control grid and the cathode of the tilting tube is galvanically connected to the control grid via an impedance, preferably an inductance.

Die vorliegende Erfindung betrifft eine Weiterbildung der durch das Hauptpatent unter Schutz gestellten Kippschaltung, die insbesondere dann Vorteile bietet, wenn ein größerer Regel- bzw. Einstellungsbereich für die Kippfrequenz erwünscht ist. Bei den bisher hierfür vorgeschlagenen Schaltungen ist das die Kippfrequenz bestimmende RC-Glied im allgemeinen in die gemeinsame Zuleitung zum Raumladegitter und Steuergitter der Kippröhre eingeschaltet. Will man bei diesen Schaltungen die Kippfrequenz in weiten Grenzen verändern, dann ist es erforderlich, den Ohmschen Widerstand des RC-Gliedes erheblich zu verändern. Durch die Vergrößerung der am RC-Glied liegenden Spannung wird jedoch das Potential des Raumladegitters verringert, und es kann schließlich auf so niedrige Werte absinken; daß der Innenwiderstand der Röhre zu groß wird und daher die Kippscbaltung nicht mehr einwandfrei arbeitet.The present invention relates to a development of the Main patent protected flip-flop circuit, the particular advantages offers when a larger control or setting range for the tilt frequency is desired is. In the circuits proposed so far for this purpose, this is the sweep frequency determining RC element in general in the common supply line to the space charge grid and control grid of the tilting tube switched on. Do you want the Change the sweep frequency within wide limits, then it is necessary to use the ohmic Change the resistance of the RC element considerably. By increasing the am If the voltage is present in the RC element, the potential of the space charge grid is reduced, and it can eventually sink to such low levels; that the internal resistance the tube is too big and therefore the Kippscbaltung no longer works properly.

Erfindungsgemäß wird bei einer gemäß den Lehren des Hauptpatentes ausgeführten Kippschaltung, bei der die Anode bzw. ein mit der Anode galvanisch verbundenes Gitter und das Steuergitter der Kippröhre über einen Transformator fest rückgekoppelt sind und das zwischen Steuergitter und Kathode liegende Raumladegitter über eine Impedanz, vorzugsweise eine Induktivität, mit dem Steuergitter galvanisch verbunden ist, das die Kippfrequenz bestimmende RC-Glied in der Zuleitung zum Steuergitter der Kippröhre, nicht aber in die dem Steuergitter und Raumladegitter geneinsame Zuleitung eingeschaltet. Im nachstehenden wird die Erfindung an Hand eines Ausführungsbeispiels beschrieben. Die Figur stellt eine Transformatorkippschaltung dar, bei der als Kippröhre eine Raumladegitterrölire verwendet wird. Die Anode i ist mit dem Steuergitter 2 der Kippröhre 3 über einen Transformator 4 fest rück- gekoppelt. Das zur Frequenzeitistellung dienende, aus Kondensator 5 und Regelwiderstand 6 be- stehende RC-Glied ist derart in die Steuergitter- zuleitung eingeschaltet, (laß es nicht in der Zulei- tung zum Raumladegitter liegt. ZNvischen Steuer- gitter 2 und Kathode 7 befindet sich ein Raumlade- gitter 8, das über eine Impedanz 9 galvanisch mit der i 2 verbunden ist. An die Anoden- wicklung' des Transformators 4 sind die Ahlenk- spulen io und ii angeschlossen. Die während der Hinlaufzeiten an den Ablenkspulen auftretende Spannung wird über die Diode als elektrische La- dungsenergie im Kondensator 1,3 gespeichert. Der Kondensator 14 dient zur Glättung der Anoden- spannung der Kippröhre. Das zum Betriel) der Kippschaltung dienende Netzger;it wird an die Klemmen i5 und 16 angeschlossen. According to the invention, in a flip-flop circuit designed according to the teachings of the main patent, in which the anode or a grid galvanically connected to the anode and the control grid of the tilting tube are permanently fed back via a transformer and the space charge grid located between the control grid and cathode via an impedance, preferably one Inductance, is galvanically connected to the control grid, the RC element that determines the tilting frequency is in the supply line to the control grid of the tilting tube, but not in the common to the control grid and space loading grid Supply line switched on. In the following, the invention is illustrated an exemplary embodiment described. The figure represents a transformer flip-flop in which A space loading grate roller is used as a tilting tube will. The anode i is connected to the control grid 2 Tilt tube 3 firmly back via a transformer 4 coupled. The one used to set the frequency from capacitor 5 and rheostat 6 standing RC element is in such a way in the control grid supply line switched on, (do not leave it in the direction to the space loading grille. ZNvischen control grid 2 and cathode 7 is a space charger grid 8, which has an impedance 9 with galvanic the i 2 is connected. To the anode winding 'of the transformer 4 are the Ahlenk coils io and ii connected. The during the Delay times occurring at the deflection coils Voltage is transmitted through the diode as an electrical charge energy stored in the capacitor 1.3. Of the Capacitor 14 is used to smooth the anode voltage of the tilting tube. That to the subject Power supply units that serve toggle switching; it is connected to the Terminals i5 and 16 connected.
