gekoppelten Dipolencoupled dipoles Zusatz zum Patent 624Addendum to patent 624 Bei schwenkbaren Adcockempiängern, bei denen, wie dies in der Abb. 1 dor Zeichnung dargestellt ist. die Dipole U1, a2 mit einem Zwischenkreis ζ über Kopplungstransformatoren L, L' symmetrisch gekoppelt sind, bietet die Herstellung einer völlig symmetrischen Kopplung häufig bedeatende Schwierigkeiten. Bei Verwendung koaxialer Spulen in der Anordnung nach Abb. 2 ist das eine Spulenende der Spule L dem Zwischenkreis näher als das andere Ende, die Kopplung daher unsymmetrisch. Legt man dagegen die Achsen der beiden Spulen L, L' parallel (Abb. 3), so ist es schwer, die Spulen so zu dimensionieren,With swiveling Adcockempiängern, in which, as shown in Fig. 1 of the drawing. the dipoles U 1 , a 2 are symmetrically coupled to an intermediate circuit ζ via coupling transformers L, L ' , the production of a completely symmetrical coupling often presents difficulties. When using coaxial coils in the arrangement according to Fig. 2, one end of the coil L is closer to the intermediate circuit than the other end, and the coupling is therefore asymmetrical. If, on the other hand, the axes of the two coils L, L 'are placed parallel (Fig. 3), it is difficult to dimension the coils in such a way that '5 daß der Kopplungskoeffizient groß genug wird, um einen guten Empfang zu gewährleisten. '5 that the coupling coefficient is large enough to ensure a good reception. Nach der Erfindung kann man die erwähnte Schwierigkeit durch Verwendung von Kopplungstransformatoren vermeiden, bei denen die eine oder die andere Spule nach dem Hauptpatent aufgebaut wird. Bei der nach dem Hauptpatent ausgeführten Induktanz sind ihre beiden Wicklungshälften so gewickelt, daß die Ganghöhe gegenüber der Spulenmitte im gleichen Sinne fortschreitet und die beiden Spulenenden angenähert in der gleichen Ebene liegen, wobei die von den benachbarten Windungen der beiden Spulenhälften umfaßten Flächen zueinander symmetrisch sind, aber sich nur teilweise überdecken. Derartige Spulen besitzen einerseits eine äußerst kleine Eigenkapazität und andererseits eine vollkommene Symmetrie gegenüber den äußeren elektrostatischen und induktiven Einflüssen, so daß durch ihre Verwendung eine vollkommene Symmetrie der Anordnung bei schwenkbaren Adcockpeilern gesichert wird.According to the invention, the aforementioned difficulty can be overcome by using Avoid coupling transformers that have one or the other coil after the main patent is built. With the inductance carried out according to the main patent their two winding halves are wound so that the pitch opposite the Coil center advances in the same sense and the two coil ends approximated in lie on the same plane, with those of the adjacent turns of the two coil halves covered surfaces are symmetrical to one another, but only partially overlap. Such coils have, on the one hand, an extremely small inherent capacitance and, on the other hand, a perfect symmetry with respect to the external electrostatic and inductive Influences, so that by using them a perfect symmetry of the arrangement is secured with swiveling Adcock direction finders.
