Description

Die neue Schaltung ist in beiliegender Zeichnung dargestellt, ι ist die Vakuumröhre, 2 deren Glühkathode, 3 das Gitter, 4 Anode. ' Von der Anode führt es über die Batterie 5 mit parallel liegendem Kondensator 6 über eine ■ Spule 7 zur Glühkathode 8. Spule 7 ist gegebenenfalls variabel. Die Antenne 9 ist über einen Variometer 10 an die Spule 7 angeschlossen oder induktiv mit derselben gekoppelt und kann noch einen Kondensator 11 aufweisen. Das Gitter 3 wird durch einen völlig unabhängigen Schwingungskreis, bestehend aus Spule 12 und Kondensator 13, erregt.The new circuit is shown in the accompanying drawing, ι is the vacuum tube, 2 its hot cathode, 3 the grid, 4 anode. It runs from the anode via the battery 5 with a capacitor 6 lying in parallel via a coil 7 to the hot cathode 8. Coil 7 is optionally variable. The antenna 9 is connected to the coil 7 via a variometer 10 or inductively coupled to the same and can also have a capacitor 11. The grid 3 is composed of a completely independent oscillation circuit Coil 12 and capacitor 13, energized.

Das Neuartige dieser Schaltung besteht darin, daß zwischen dem Schwingungssystem des Gitters und dem Anodenkreise keinerlei induktive oder kapazitive Kopplung besteht. Dies bedeutet gegenüber dem Stande der Technik insofern etwas Neues, als man bisher eine Rückkopplung zwischen dem Anödenkreise als demjenigen, welcher die verstärkten Schwingungen führt, und dem Gitterkreise, welcher zur .Steuerung und Aufrechterhaltung der Schwingungen dient, für notwendig gehalten hat. Während die bskannten Schaltungen den Nachteil haben, entweder nur für die Erzeugung sehr schneller oder nur für die Erzeugung verhältnismäßig langsamer Schwingungen geeignet zu sein, zeigt sich, daß die vorliegende Schaltung ein fast unbegrenztes Gebiet von Wellenlängen zu erzeugen gestattet und mit einem ganz vorzüglichen Wirkungsgrad arbeitet. Vor allem treten auch keinerlei störende Nebenschwingungen auf. Die erzeugte Wellenlänge ist vielmehi^y^Iig^emvggUig^ woraus sich nach Meinung derXnmelder der vorzügliche Wirkungsgrad erklärt. ,The novelty of this circuit is that between the oscillation system of the There is no inductive or capacitive coupling in the grid and the anode circuit. Compared to the state of the art, this means something new to the extent that it was previously a feedback between the anode circuits as the one that generated the amplified vibrations leads, and the grid circles, which for .Control and maintenance of the Vibrations serves, has considered necessary. While the known circuits use the Have disadvantage, either only for the generation very quickly or only for the generation to be suitable for relatively slow vibrations, it turns out that the present Circuit allows and with an almost unlimited range of wavelengths to be generated works at an excellent level of efficiency. Above all, there are also no disruptive secondary vibrations on. The generated wavelength is much more emvggUig ^ y ^ Iig ^ from which we can see The reporter's opinion explains the excellent efficiency. ,

■Zur Vermeidung von Nebenschwingungen ist es wesentlich, die Antenne mit dem Anodenkreis zu koppeln, und zwar vorzugsweise galvanisch. Die Einstellung verschiedener beliebiger Wellenlängen erfolgt durch Einstellung des Gitterkreises auf die gewünschte Welle und Nachstimmung der Antenne auf das Maximum des Ausschlages..■ To avoid secondary vibrations, it is essential to connect the antenna to the anode circuit to be coupled, preferably galvanically. Setting various arbitrary Wavelengths is done by setting the grating circle to the desired wave and Adjustment of the antenna to the maximum of the deflection.
