EMI3.1 1. Einrichtung zur übertragung von Zeichen mittels elektromagnetischer Wellen, bei welcher die Anzeigen in der Empfangsstation durch die Wechselwirkung zweier Kraftfelder hervorgerufen werden, von denen das eine durch die aufgefangenen Impulse oder Schwingungen und das andere durch örtlich erzeugte Impulse oder Schwingungen erzeugt wird, dadurch gekennzeichnet, dass die örtlichen Impulse oder Schwingungen kontinuierlich durch eine ununterbrochen wirksame Wechselstromquelle von sehr hoher Frequenz erzeugt werden, z. B. EMI3.1 1. Device for the transmission of characters by means of electromagnetic waves, in which the displays in the receiving station are caused by the interaction of two force fields, one of which is generated by the captured pulses or vibrations and the other by locally generated pulses or vibrations, characterized that the local impulses or vibrations are continuously generated by an uninterrupted source of alternating current of very high frequency, e.g. B. Wechselstrommaschine 5, deren Frequenz um einen geringen Betrag von der Frequenz der aufgefangenen Impulse oder Schwingungen abweicht, so dass die Schwebungen zwischen den ortlich erzeugten und den aufgefangenen Impulsen zur Erzeugung eines hörbaren Signales, zum Beispiel eines musikalischen Tones benützt werden. AC machine 5, the frequency of which deviates by a small amount from the frequency of the captured pulses or vibrations, so that the beats between the locally generated and the captured pulses are used to generate an audible signal, for example a musical tone. 2, Ausführungsform der Einrichtung nach Anspruch I, dadurch gekennzeichnet, dass der zur Erzeugung des örtlichen Kraftfeldes dienende kontinuierlich wirksame Wechselstromerzeuger gleichzeitig zum Aussenden von Zeichen dient und mit dem Sendestromkreis fest oder lose gekoppelt ist. 2, embodiment of the device according to claim 1, characterized in that the continuously effective alternating current generator serving to generate the local force field is used at the same time to transmit characters and is permanently or loosely coupled to the transmitting circuit. 3. Ausführungsform der Einrichtung nach Anspruch 1 und 2, dadurch gekennzeichnet, dass zwecks Gleichhaltung der Belastung des Wechselstromerzeugers (5) abwechselnd der Sendestromkreis (6) und ein denselben Widerstand darbietender zweiter Stromkreis (37, 38) durch die Sendetaste (7) mit dem Erzeuger (5) gekoppelt werden. 3. Embodiment of the device according to claim 1 and 2, characterized in that in order to keep the load on the alternator (5) alternating between the transmission circuit (6) and a second circuit (37, 38) presenting the same resistance through the transmission button (7) with the Generator (5) are coupled.
