Description

Die Erfindung- betrifft eine Einrichtung zur drahtlosen Telegraphie und Telephonie mit Wechselstrombetrieb. Man hat bereits vorgeschlagen, Vakuumröhren mit Wechselstrom. der üblichen Periodenzahl zu betreiben, indem Wechselstrom hoher Spannung, z. B. unter Zwischenschaltung von Transformatoren, als Anoden- und Heizstrom an Stelle von Gleichstrom dem Vakuumschwingungserzeuger zugeführt wind.. Andererseits hat man schon daran gedacht, Wechselstrom einer Frequenz von mehreren Tausend für die Zwecke der drahtlosen Telephonie, z. B. in der Duddellschaltung, zu benutzen.The invention relates to a device for wireless telegraphy and telephony with AC operation. It has already been proposed to use alternating current vacuum tubes. to operate the usual number of periods by alternating current of high voltage, e.g. B. with the interposition of transformers, as anode and heating current instead of direct current to the vacuum oscillation generator fed wind .. On the other hand, one has already thought of using alternating current one Frequency of several thousand for wireless telephony purposes, e.g. Am the Duddell circuit to use.

Gemäß der Erfindung wird eine Schwingungserzeugungseinrichtung mit Vakuumröhren und eine Hochfrequenzmaschine von einer den ausgesandten Ton unhörbar machenden Frequenz zu einer Einrichtung für drahtlose Telegraphie und Telephonie verbunden, bei welcher der Wechselstrom als völlig gleichwertiger Ersatz für Gleichstromwirkt. Es wird auf diese Weise möglich, die schweren Hochspannungsbatterien durchAccording to the invention there is a vibration generating device with vacuum tubes and a high frequency machine from one the emitted sound inaudible making frequency a facility for wireless telegraphy and telephony connected, in which the alternating current acts as a completely equivalent substitute for direct current. In this way it becomes possible to carry the heavy high voltage batteries

as die leichteren Hochfrequenzmaschinen zu ersetzen, was z. B. bei Stationen auf Flugzeugen von großer Bedeutung ist. Die erforderlichen hohen Spannungen können in einfacher Weise mittels eines Transformators erzeugt werden. Auch ist die Erzeugung und Bedienung von Wechselstrom im allgemeinen leichter möglich, als vom Gleichstrom. Es kann sowohl der Glühstromkreis, als auch der Anodenstromkreis mit Wechselstrom gespeistas to replace the lighter high frequency machines, what z. B. is of great importance at stations on airplanes. The necessary high voltages can easily be achieved by means of a transformer be generated. The generation and operation of alternating current is also general more easily possible than from direct current. Both the glow circuit and the Anode circuit supplied with alternating current

werden. Für den Glühstromkreis kommt man mit geringeren Wechselzahlen aus, indem z. B. bei einem Glühfaden mit hinreichend großer Wärmeträgheit schon 1000 Perioden genügen. Tm Anodenstromkreis sind die Periodenzahlen zweckmäßig höher zu wählen, und zwar vorzugsweise in der Größenordnung von 10 bis 20000.will. For the glow circuit you get by with lower alternation numbers by z. B. with a filament with sufficiently large thermal inertia already 1000 periods suffice. In the anode circuit, the number of periods should expediently be selected higher, preferably on the order of 10 to 20,000.

Durch entsprechende Erniedrigung der Periodenzahl hat man es in der Hand, Töne auszusenden, was für viele Zwecke von Bedeutunig ist. Wenn beispielsweise eine ungedämpfte Station mit einer gewöhnlichen Erdstation verkehren will, welche über besondere Einrichtungen zum Empfang- ungedämpfter Schwingungen nicht verfügt, so bewährt sich die Verwendung von Wechselstrom zur Heizung des Glühfadens oder zur Speisung.des Anodenstromkreises als ein besonders einfaches Mittel. Zugleich hat man es dann in der Hand, durch bloße Steigerung der Periodenzahl den Ton zu verändern bzw. unhörbar zu machen, so daß man nach Belieben telegraphische oder telephonische Nachrichten übermitteln kann.By lowering the number of periods accordingly one has it in hand, tones send out, which is important for many purposes. For example, if an undamped Station wants to operate with an ordinary earth station, which has special facilities for receiving undamped Does not have vibrations, the use of alternating current for heating has proven itself of the filament or for feeding the anode circuit as a particularly simple one Middle. At the same time you have it in your hand, simply by increasing the number of periods to change the sound or to make it inaudible, so that one telegraphic at will or transmit telephonic messages.
