Description

Einrichtung zum Tasten von Hochfrequenzgeneratoren mittels hilfsmagnetisierter Eisendrosseln. Beim Telegraphieren mittels hochfrequenter Schwingungen ist es in vielen Fällen sehr erwünscht, daß die zur Erzeugung der Schwingungen dienenden Generatoren während des Tastens eine gleichmäßige Belastung beibehalten.Device for touching high-frequency generators by means of auxiliary magnetized Iron chokes. When telegraphing using high-frequency vibrations, it's in In many cases it is very desirable that the generators used to generate the vibrations Maintain an even load during the keying.

Gemäß der vorliegenden Erfindung erfolgt dieses bei mit Zwischenkreis arbeitenden Generatoren dadurch, daß parallel zu den hilfsmagnetisierten Eisendrosseln, die nicht im Antennenkreis liegen, ein Widerstand geschaltet wird.According to the present invention, this takes place with an intermediate circuit working generators in that parallel to the auxiliary magnetized iron chokes, which are not in the antenna circuit, a resistor is switched.

In der Zeichnung bedeutet Gr den Generator, z. B. einen Lichtbogengenerator, C, und C2 sind Blockkondensatoren. C3 und L1 sind die Absiimmittel, D1 die Zwischenkreisdrossel, zu deren Hochfrequenzspule ein Widerstand .W im Nebenschluß liegt. L2 ist die mit dem Zwischenkreis gekoppelte Antennenabstimmspule, die über eine Drossel D2 an die Erde angeschlossen ist.In the drawing, Gr means the generator, e.g. B. an arc generator, C, and C2 are block capacitors. C3 and L1 are the protective devices, D1 the intermediate circuit choke, to whose high-frequency coil a resistor .W is shunted. L2 is the one with The antenna tuning coil coupled to the intermediate circuit, which is connected to the Earth is connected.

Während des Ausstrahlens der Schwingungen sind die Drosseln Dl und D2 gesättigt, und es fällt somit bei gedrückter Taste T die Drosselwirkung aus. Bei nicht gedrückter Taste, d. h. bei nicht gesättigter Drossel, ist die Antenne durch die Drossel abgeschaltet. Die Energie wird nun auf den parallel zu der Hochfrequenzspule der Zwischenkreisdrossel geschalteten Widerstand W geleitet, durch dessen Bemessung ein einfaches Mittel gegeben ist, die Leistung des Generators so zu regeln, daß eine gleichmäßige Belastung desselben während des gesamten Betriebes erzielt wird. Die Drossel D@1 wirkt in diesem Fall nur als Relais für den Widerstand W.While the vibrations are being emitted, the throttles D1 and D2 are saturated, and the throttling effect is therefore deactivated when the T key is pressed. If the button is not pressed, ie if the throttle is not saturated, the antenna is switched off by the throttle. The energy is now conducted to the resistor W, which is connected in parallel to the high-frequency coil of the intermediate circuit choke and whose dimensioning provides a simple means of regulating the output of the generator in such a way that it is uniformly loaded during the entire operation. In this case, the throttle D @ 1 only acts as a relay for the resistance W.
