  Spulen für Empfangsschaltungen der Hochfrequenz-Telegraphie und-Telephonie. 



   Es sind Spulen für   Empfangsschaltungen   der Hochfrequenztelegraphie und-telephonie bekannt, bei welchen es besonders zweckmässig ist, die Kerne bei Spulen für   Empfangsschaltungen   aus dünnem Draht von weniger als O'l mm Durchmesser zu machen. 



   Die vorliegende Erfindung besteht nun darin, auch für diese Kerne Nickeleisenlegierungen zu verwenden. Besonders geeignet erscheint die sogenannte Permalloy-Legierung, die ungefähr   80%   Nickel und 20% Eisen enthält. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Coils for receiving circuits in high-frequency telegraphy and telephony.



   Coils for receiving circuits in high-frequency telegraphy and telephony are known, in which it is particularly expedient to make the cores of coils for receiving circuits from thin wire less than 1/1 mm in diameter.



   The present invention now consists in using nickel iron alloys for these cores as well. The so-called permalloy alloy, which contains approximately 80% nickel and 20% iron, appears particularly suitable.
