Zusatz zum Patent 379222.Addendum to patent 379222.

Patentiert im Deutseben Reiche vom 2. Dezember 1923 ab. Längste Dauer: 24. April 1937.Patented in Deutseben Reiche on December 2nd, 1923. Longest duration: April 24, 1937.

Im Patent 379222 ist eine Schaltung angegeben, die darauf beruht, daß die Maschine ganz oder teilweise von wattlosen Strömen entlastet wird. Dieses wird nach der Erfindung dadurch erreicht, daß parallel zum Umformer eine Kapazität geschaltet ist, welche ganz oder teilweise tlen Magnetisierungsstrom für den Umformer hergibt. Diese Anordnung hat aber den Nachteil, daß die höheren Harmonischen teilweise in den Kapazitätszweig gelangen und den Kondensator belasten, so daß eine Erhitzung desselben eintritt.A circuit based on the machine is completely or partially relieved of wattless currents. This is according to the invention achieved in that a capacitance is connected in parallel to the converter, which wholly or partially tlen magnetizing current for the converter. This arrangement but has the disadvantage that the higher harmonics are partly in the capacitance branch arrive and load the condenser, so that heating of the same occurs.

Außerdem entsteht bei einer solchen Anordnung leicht Doppelwelligkeit, die wohl darauf zurückzuführen ist, daß der aus den Wicklungen und der ParalleTkapiz'ität bestehende Kreis zu Eigenschwingungen angestoßen wird.In addition, with such an arrangement, double waviness is easily created, which is probably due to it is due to the fact that the existing from the windings and the ParalleTkapiz'ität Circle is triggered to natural oscillations.

Die Erfindung besteht nun darin, daß man in den durch die Kapazität und die Transformatorwicklungen gebildeten Kreis einenThe invention consists in that one in the through the capacitance and the transformer windings formed circle

ίο aus einer Selbstinduktion und einer Kapazität bestehenden Zweig, welcher ganz oder annähernd auf die Grundwelle abgestimmt ist, einschaltet. Dieser Zweig ändert für die Grundwelle nicht die Verhältnisse, wohl aber bildet er ein Sperrsystem für die höheren Harmonischen, die daher von der Parallelkapazität ferngehalten werden und im günstigen Wirkungsgrad auf die Antenne übertragen werden können.ίο from a self-induction and a capacity existing branch, which is fully or approximately matched to the fundamental wave, turns on. This branch does not change the conditions for the fundamental wave, but it does it forms a blocking system for the higher harmonics, which is therefore caused by the parallel capacitance are kept away and can be transmitted to the antenna with low efficiency.

In den beiliegenden Zeichnungen sind zwei Ausführungsbeispiele der Erfindung angegeben. In der Abb. 1 ist das Sperrsystem in die Verbindung zwischen der Primärwicklung und der Parallelkapazität eingeschaltet, während nach Abb. 2 dieses Sperrsystem in dem Kondensatorzweig liegt.Two exemplary embodiments of the invention are given in the accompanying drawings. In Fig. 1 the locking system is in the connection between the primary winding and the parallel capacitance switched on, while according to Fig. 2 this locking system in the capacitor branch lies.
