Ein Relais 21 mit zwei Elektromagneten. in Serie mit dem Kondensator 22. mit einem Kondensator 23 in Brücke, ist mit der Primärwicklung der Abgabeübertragerspule 20 in Reihe geschaltet. Die Kondensatoren 22 und 23 sind beziehungsweise von solcher Kapazität, dass der Stromkreis, der die Primär- wicklung des Abgabestransformators 20 und den Kondensator 23 in Reihe geschaltet enthält, bei Strömen von Spreehfrequenzen mitselhwingt und der Parallelstromkreis. der die Wicklungen des Relais 27 und den Kondensator 22 enthält. bei Strömen von Rufstromfrequenz mitschwingt. Es ist daher klar. dass das Relais 21 durch Telephonströme nicht beeinflusst werden wird.
Mit der Sekundärwicklung der Abgabe-

Es wird nun angenommen, dass Rufstrom oder andere Strome mit Charakteristiken, die von jenen der Telephonströme verschieden sind, zur Übertragerstation über den Leitungsabschnitt 11 geschickt werden. Dieser Rufstrom geht vom Leitungsabschnitte 11 über die Sekundärwicklungen der Abgabe-

beschriebenen Weise kurz. Das Relais 31 wird daher sofort abfallen, das Relais 41 zum Ansprechen bringen und den Stromkreis des Relais 28 offenen.
Mit anderen Worten, während beide Relais 21 und. 31 durrh Rufstrom, der von irgend einem Leitungsabschnitte zur Übertragerstation kommt, betätigt werden können, wird nur das Relais, welches den verstärkten Rufstrom empfängt, betätigt bleiben.
Der verstärkte Rufstrom geht über die Wicklungen des Relais 27, geht auch über die Primärwicklung der Abgabeübertragerspule 20 und als Resultat endlich wird der verstärkte Rufstrom in der Sekundärwicklung derselben induziert, welche im Stromkreise des Leitungsabschnittes 12 liegt.
Diese Rufstromübertragung über den Leitungsabschnitt 11 verstärkt bei der Übertragerstation, wie beschrieben, und sodann auf den Leitungsabschnitt 72 induziert. kann zur Betätigung von Signaleiurichtungen irgend einer Art verwendet werden.
Hieraus ergibt sich, dass der Apparat funktioniert, um den über Linienabschnítt 12 einlangenden Rufstrom zu empfangen, zu verstärken und sodann diesen verstärkten Strom auf den Linienabschnitt 11 zu übertragen.

A relay 21 with two electromagnets. in series with the capacitor 22, with a capacitor 23 in bridge, is connected in series with the primary winding of the output transformer coil 20. The capacitors 22 and 23 are or respectively of such a capacity that the circuit, which contains the primary winding of the output transformer 20 and the capacitor 23 connected in series, resonates with currents of speaking frequencies and the parallel circuit. which contains the windings of the relay 27 and the capacitor 22. resonates with currents of ringing current frequency. It is therefore clear. that the relay 21 will not be affected by telephone currents.
With the secondary winding of the delivery

Transfer coil 20 connected and act in the same way. An artificial compensating line 34 is also connected with the delivery transfer coil 30.
It is now assumed that ringing currents or other currents having characteristics different from those of the telephone currents are sent to the transmitter station via the line section 11. This ringing current goes from the line sections 11 via the secondary windings of the output

If now ringing current comes from the line sections 11. it first goes through the secondary windings of the delivery transformer coil 30, where sufficient current is induced in the primary winding of the same. to operate the relay 31. whereby the relay 41 is released immediately and the relay 28

described way briefly. The relay 31 will therefore drop out immediately, the relay 41 will respond and the circuit of the relay 28 will open.
In other words, while both relays 21 and. 31 so that ringing current coming from any line section to the transmission station can be actuated, only the relay that receives the amplified ringing current will remain actuated.
The amplified ringing current goes over the windings of the relay 27, also goes over the primary winding of the output transmitter coil 20 and as a result, finally, the amplified ringing current is induced in the secondary winding of the same, which is in the circuit of the line section 12.
This ringing current transmission via the line section 11 is amplified at the transmitter station, as described, and is then induced onto the line section 72. can be used to actuate signaling devices of any kind.
As a result, the apparatus functions to receive and amplify the ringing current arriving via line segment 12 and then to transmit this amplified current to line segment 11.
