Die im Hauptpatent beschriebene Taktrelaisschaltung für Fernmelde-, insbesondere Fernsprechanlagen betrifft eine Schaltungsanordnung mit nur einem Relais, das durch einen Kondensatorstromstoß zum Ansprechen und nach Umladung des Kondensators durch einen zweiten Kondensatorstromstoß entgegengesetzter Richtung wieder zum Abfall gebracht wird, was dadurch erreicht wird, daß über einen einen Selbsthaltestromkreis schließenden Kontakt des Taktrelais gleichzeitig der Umladestromkreis des Kondensators verläuft und daß der gleiche Kontakt an einem festen Potential liegt und daß der Umladestromkreis des Kondensators über einen von dem den Taktvorgang steuernden Impulskontakt unabhängigen Stromkreis verläuft.The clock relay circuit described in the main patent for telecommunications, in particular telephone systems relates a circuit arrangement with only one relay, which is triggered by a capacitor surge and after reloading the capacitor by a second capacitor surge in the opposite direction is brought to waste, which is achieved in that Via a contact of the clock relay that closes a self-holding circuit, the recharging circuit of the Capacitor runs and that the same contact is at a fixed potential and that the charge reversal circuit of the capacitor via a circuit that is independent of the pulse contact controlling the clocking process runs.
Das Laden bzw. Umladen des als Energiespeicher wirkenden Kondensators, der fest in Brücke zu zwei Spannungsteilern geschaltet ist, erfolgt über zwei voneinander verschiedene Stromkreise, die abwechselnd in Abhängigkeit vom Erregungszustand des Taktrelais geöffnet und geschlossen werden. Zur Steuerung werden dabei ein Arbeits- und ein Ruhekontakt benötigt, die zu einem Umschaltekontakt zusammengefaßt sind und veränderliche Widerstände der Spannungsteiler darstellen.The charging or reloading of the capacitor acting as an energy store, which is firmly in the bridge to two Voltage dividers is switched, takes place via two different circuits that alternate in Open and close depending on the excitation state of the clock relay. Become a control this requires a working and a normally closed contact, which are combined to form a changeover contact and are variable Represent the resistances of the voltage dividers.
Häufig steht zur Lösung der gleichen Aufgabe nur ein Relaiskontakt zur Verfügung. Es ist daher Zweck der Erfindung, eine solche Schaltungsanordnung zu schaffen, die bei gleichem Aufwand an anderen Schaltmitteln, wie Widerstände, Kondensator und Relaiswicklungen, nur einen Relaiskontakt zur Steuerung benötigt. Dieses wird dadurch erreicht, daß der fest in Brücke mit zwei Spannungsteilern angeordnete Kondensator zum Laden in der einen Stromrichtung in einen vom Relaiskontakt unabhängigen Ladestromkreis geschaltet ist und daß das Umladen des Kondensators über einen zweiten vom einzigen, einen veränderlichen Widerstand in einem der Spannungsteiler darstellenden Steuerkontakt des Taktrelais abhängigen Ladestromkreis erfolgt.Often only one relay contact is available to solve the same task. It is therefore the purpose of Invention to create such a circuit arrangement that with the same effort on other switching means, such as Resistors, capacitor and relay windings, only one relay contact required for control. This will achieved in that the fixed in bridge with two voltage dividers arranged capacitor for charging in the one current direction is connected to a charging circuit independent of the relay contact and that the Reloading of the capacitor via a second from the only one, a variable resistor in one of the Voltage divider representing control contact of the clock relay-dependent charging circuit takes place.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt, dessen Arbeitsweise nachstehend erläutert werden soll:The drawing shows an exemplary embodiment, the mode of operation of which will be explained below:
Im Ruhezustand ist der Kondensator K geladen:In the idle state, the capacitor K is charged:

Die in diesem Stromkreis liegende Wicklung (II) des Relais Z erhält Fehlstrom, so daß das Relais nicht anzieht. Beim ersten Impuls schließt der Impulskontakt i und schaltet den Kondensator K parallel zu der Wicklung (I) des Relais Z. Durch den Entladestromstoß spricht das Z-Relais an und hält sich über seinen Kontakte in einem StromkreiszweigThe winding (II) of relay Z in this circuit receives fault current so that the relay does not pick up. With the first impulse the impulse contact i closes and switches the capacitor K parallel to the winding (I) of the relay Z. The Z-relay responds due to the discharge current surge and stays in a circuit branch via its contacts

Bei Einsetzen des zweiten Impulses wird die Wicklung I des Relais Z erneut parallel zum Kondensator geschaltet und von einem Strom entgegengesetzter Richtung durchflossen, so daß die Erregung der Wicklung (I) der Erregung der Wicklung (II) entgegenwirkt. Das Z-Relais fällt ab, und der Stromkreis 1 ist erneut hergestellt.When the second pulse starts, the winding I of the relay Z is again connected in parallel to the capacitor and a current in the opposite direction flows through it, so that the excitation of the winding (I) counteracts the excitation of the winding (II). The Z relay drops out and circuit 1 is re-established.
