Hochfrequenzspule.

ist, der insbesondere überwiegend aus Luft und teilweise aus einem andern verlustarmen Isolierstoff besteht. Es hat sich nämlich eigenartigerweise gezeigt, dass trotz der durch den Abstand zwischen Kern und Wicklung verursachten Verringerung der Selbstinduktion, welche eine Verlängerung des Kupferweges und somit eine Vergrösserung des Ohmschen Widerstandes bedingt, die Güte der Spule zunimmt.
In den Fig. 3 und 4 sind Ausführungsbeispiele der erfindungsgemässen Hochfrequenzspulen dargestellt. Fig. 3 zeigt ein beispielsweise aus Polystyrol bestehendes dünnwandiges Isolierrohr 7, auf welchem die gemäss Fig. 1 und 2 hergestellte fortschreitende Kreuzwieklung 8 aufgebracht ist, während im Innern des Isolierrohres 7 der stabförmige Eisenkern 9 unter Einhaltung des für die Güte der Spule wichtigen lichten Abstandes 23 angeordnet ist. Der Eisenkern 9 kann mit der Schraube 10, welche vorzugsweise mittels eines Zapfens 11 in den Kern eingeklebt oder eingeschraubt ist, axial gegen die Wicklung 8 verschoben werden, wodurch sich eine sehr gleichmässige und feinfühlige Änderung der Selbstinduktion ergibt. Spulenkörper 7 und Schraube 10 sind in einem Befestigungsteil ange-

is, which in particular consists predominantly of air and partly of another low-loss insulating material. Strangely enough, it has been shown that despite the reduction in self-induction caused by the distance between the core and the winding, which causes the copper path to be lengthened and thus the ohmic resistance to be increased, the quality of the coil increases.
In FIGS. 3 and 4, exemplary embodiments of the high-frequency coils according to the invention are shown. Fig. 3 shows a thin-walled insulating tube 7, for example made of polystyrene, on which the progressive cross shape 8 produced according to FIGS. 1 and 2 is applied, while inside the insulating tube 7 the rod-shaped iron core 9 while maintaining the clearance important for the quality of the coil 23 is arranged. The iron core 9 can be moved axially against the winding 8 with the screw 10, which is preferably glued or screwed into the core by means of a pin 11, which results in a very uniform and sensitive change in the self-induction. Bobbin 7 and screw 10 are attached in a fastening part.
