 in welche die Anordnung eingeschaltet werden soll. Für die   Rufströme geringer   Frequenz wirken dagegen die Kondensatoren als grosse Widerstände, weshalb diese Ströme die Wege A, B, E, 0, D   und a', B', E', C', D' wählen, Um gute Übertragung, der Rufstrome zu erhalten, kann somit die Rufstromspule in der Weise konstruiert werden, dass die Wirkung derselben auf die Übertragung   die bestm0glichste wird. Nach der Theorie soll diese Spule mit vielen Wmdungen gewickelt werden und einen Eisenkern mit geringem magnetischen Widerstande haben. Der Eisenkern wird daher nach denjenigen Prinzipien konstruiert, die   gewöhnlich   für Transformatoren gelten. 



   Man kann auch eine Parallelschaltung beider Spulen verwenden. Die entsprechende An-

   PATENTANSPRÜCHE :
1. Übertrager für Fernsprechleitungen, gekennzeichnet durch die Vereinigung von zwei Induktionsspulen, die in Bezug auf ihre elektrischen und magnetischen Eigenschaften so   beschaffen   sind, dass die eine den hochfrequenten Sprechstrnmen und die andere den niederfrequenten Ruf-   strömen   angepasst ist.

 in which the arrangement is to be switched on. For the low frequency ringing currents, however, the capacitors act as large resistors, which is why these currents choose the paths A, B, E, 0, D and a ', B', E ', C', D ', for good transmission, the ringing currents Thus, the ringing current coil can be designed in such a way that the effect thereof on the transmission becomes the best possible. According to the theory, this coil should be wound with many turns and have an iron core with low magnetic resistance. The iron core is therefore designed according to the principles that usually apply to transformers.



   You can also use a parallel connection of both coils. The corresponding
