Schaltungsanordnung für Frequenz-Vervielfachungs-Transformatoren, insbesondere für
Radiotechnik.

<Desc/Clms Page number 2>
Wie aus der Zeichnung ersichtlich, findet sich in dem Sekundärkreis ausser der Selbstinduktion des Transformators 4, dem Kondensator und den Kopplungswindungen 6 keine weitere Induktionsspule angedeutet, was dahin zu verstehen ist, dass in diesen Sekundärkreis nur die zur Kopplung mit dem Zwischenkreis unbedingt notwendige Selbstinduktion eingeschaltet sein soll, weil es nach Möglichkeit anzustreben ist, die Kapazität in diesem Kreise so gross wie nur irgend möglich zu machen, damit der Ohmsehe Widerstand möglichst klein wird. Ferner ist es für die schnelle Änderung bzw.
Einstellung der Wellenlänge von erheblichem Vorteil, dass die Zwischenkreiskopplungen 6 und 9 für die verschieden grossen Weller als variable Kopplungen ausgebildet sind, weil andernfalls bei Anwendung fester Kopplungen durch mechanisches Zuschalten und Abschalten von Kopplung & windungen die Genauigkeit der Einstellung erschwert sein würde.
PATENT-ANSPRÜCHE :
1. Schaltungsanordnung für Frequenz-Vervielfachungstransformatoren, bei denen die höheren Frequenzen durch Kurvenverzerrung infolge hoher Sättigung erzeugt und herausgefiltert werden und die gleichsinnig magnetisiert sind, insbesondere für Radiotechnik, zur Unterdrückung unerwünschter Nebenoder Oberwellen in der Antenne, dadurch gekennzeichnet, dass zwischen dem Sekundärkreis des Frequenz-Vervielfaehungstransformators und der Antenne ein Energie übermittelnder, auf die Antennenfrequenz abgestimmter Zwischenkreis eingeschaltet ist.

Radio technology.

<Desc / Clms Page number 2>
As can be seen from the drawing, apart from the self-induction of the transformer 4, the capacitor and the coupling windings 6, there is no further induction coil indicated in the secondary circuit, which is to be understood as meaning that only the self-induction which is absolutely necessary for coupling to the intermediate circuit is switched on in this secondary circuit should be, because it is desirable to make the capacitance in this circuit as large as possible so that the ohmic resistance is as small as possible. It is also useful for quick changes or changes.
Setting the wavelength is of considerable advantage that the intermediate circuit couplings 6 and 9 are designed as variable couplings for the different sized waves, because otherwise the accuracy of the setting would be more difficult when fixed couplings are used by mechanical switching on and off of couplings and windings.
PATENT CLAIMS:
1. Circuit arrangement for frequency multiplier transformers, in which the higher frequencies are generated and filtered out by curve distortion due to high saturation and which are magnetized in the same direction, especially for radio technology, to suppress unwanted spurious or harmonics in the antenna, characterized in that between the secondary circuit of the frequency -Verielfaehungstransformators and the antenna an energy-transmitting intermediate circuit tuned to the antenna frequency is switched on.
