Description

Die Erfindung bezieht sich auf eine Hochfrequenzeinrichtung zur Behandlung eines Gutes im Feld elektromagnetischer Wellen sehr hoher Frequenz unter Verwendung einer an die Energiequelle angeschlossenen Verzögerungsleitung in Form einer Wendel nach Patent 962 364, bei der das Gut im axialen Feld der einpoligen wenigstens annähernd strahlungsfreien Verzögerungsleitung untergebracht wird. In weiterer Ausgestaltung der im Hauptpatent vorgeschlagenen Hochfrequenzeinrichtung ist erfindungsgeniäß vorge- xo sehen, daß das der Energiequelle abgewandte Ende der Wendel mit einer reflektierenden Fläche abgeschlossen ist, die den Durchtritt des Gutes gestattet. Diese reflektierende Fläche dient als Reflektor für die AVellen, die vom anderen Ende der Welle her an dieser entlanglaufen, und verbessert den Wirkungsgrad der als Strahler arbeitenden Wendel.The invention relates to a high-frequency device for treating an item in the electromagnetic field Very high frequency waves using one connected to the power source Delay line in the form of a helix according to patent 962 364, in which the material in the axial field of the single-pole at least approximately radiation-free delay line is accommodated. In further The design of the high-frequency device proposed in the main patent is proposed according to the invention see that the end of the coil facing away from the energy source is terminated with a reflective surface that allows the goods to pass through. This reflective surface serves as a reflector for the A-cells coming from the other end of the shaft run along this, and improves the efficiency of the filament working as a radiator.

In der Zeichnung ist als Ausführungsbeispiel der Erfindung ein Strahler dargestellt, der zur Verwendung mit einer Einrichtung nach dem Hauptpatent bestimmt ist und sich insbesondere für die Behandlung von langgestreckten Hölzern geringen Querschnittes eignet. Er hat eine Wendel 10, deren Tragkonstruktion der besseren Übersichtlichkeit wegen nicht dargestellt ist. Die Wendel ist an ihrem einen Ende mit einer Scheibe 11 verbunden, die eine Öffnung vom Wicklungsdurchmesser der Wendel hat. Durch diese Öffnung können die zu behandelnden Holzstäbe 15 in die Wendel eingeschoben werden, wobei die Scheibe 11 als Reflektor der Wellen dient, die vom anderen Ende der Wendel her an dieser entlanglaufen. Dieses Ende ist über ein Anpassungsstück 13 und eine Kupplung 12 mit der Hochfrequenzleitung 8 verbunden. Zur Anpassung der Hochfrequenzleitung an die Wendel ist der über die Kupplung 12 hinweggeführte Außenleiter der Koaxialleitung in dem Anpassungsstück 13 trichterförmig erweitert; ferner hat die Wendel 10 in ihren ersten Windungen eine größere Steigung, die in den. folgenden Windungen allmählich abnimmt. HochfrequenzeinrichtungIn the drawing, a radiator is shown as an embodiment of the invention, which for use with a device according to the main patent is intended and in particular for the treatment of elongated wood with a small cross-section. It has a helix 10, the supporting structure of which is not shown for the sake of clarity. The helix is on one of them End connected to a disc 11 which has an opening the winding diameter of the helix. The wooden rods 15 to be treated can be pushed into the helix through this opening, with the disc 11 serves as a reflector of the waves which run along the helix from the other end thereof. This end is connected to the high-frequency line 8 via an adapter 13 and a coupling 12 tied together. In order to adapt the high-frequency line to the helix, the one passed over the coupling 12 Outer conductor of the coaxial line expanded in a funnel shape in the adapter 13; also has the coil 10 in its first turns has a greater pitch, which in the. following turns gradually decreases.
