Description
Einrichtung zur drahtlosen Nachrichtenübermittlung mit elektrischen Wellen. Die Erfindung betrifft eine Einrichtung zur Nachrichtenübermittlung, insbesondere zur Telephonieübertragung mit elektrischen Wellen, die durch Kathodenstrahlröhren in Sende- und Empfangsschaltung erzeugt bzw. aufgenommen werden. Es ist bekannt, mit der Welle, auf der die Nachrichtenübermittlung selbst durchgeführt werden soll, gleichzeitig auch den Anruf durchzuführen. Sowohl der Verkehr zwischen zwei Stationen als auch der Anruf wird daher auf seiten der anrufenden Station mittels elektrischer Wellen durchgeführt, und die Welle für den Verkehr wird gleichgewählt mit derjenigen für den Anruf.Device for the wireless transmission of messages with electrical Waves. The invention relates to a device for transmitting messages, in particular for telephony transmission with electric waves passing through cathode ray tubes are generated or recorded in the transmitting and receiving circuit. It is known, with the wave on which the message transmission itself is to be carried out, make the call at the same time. Both the traffic between two stations as well as the call is therefore made on the part of the calling station by means of electrical Waves carried out, and the wave for traffic is chosen the same as that for the call.
Des weiteren ist es bekannt, jedem Teilnehmer eine besondere Verkehrsweile zuzuordnen, so daß mit dem Einstellen der Verkehrswelle bei der anrufenden Station sowohl die Auswahl des Teilnehmers erfolgt als auch der Anruf unter Verwendung dieser Welle ermöglicht ist.Furthermore, it is known that each participant has a special traffic time assign, so that with the setting of the traffic wave at the calling station both the selection of the subscriber and the call are made using this Wave is enabled.
Es ist weiterhin bekannt, zur Einstellung der Verkehrswelle Druckknöpfe, Schleifer, Drehscheiben o. dgl. zu benutzen, welche die zur Erzeugung oder zum Empfang der elektrischen Wellen zugehörigen Schwingungskreise entsprechend verändern bzw. abstimmen. Gemäß der vorliegenden Erfindung jedoch sollen bei einer Sende- oder Empfangsschalteng für Glühkathodenröhren, die ohne äußere schaltungstechnische Rückkopplung zwischen Gitter und Anodenkreis arbeiten, eine zwangläufige Verbindung dieser beiden Irreise vorgesehen sein. Die Bedienung dieser zwangläufigen Verbindung kann auch gleichzeitig mit dein Wellennehmerwähler erfolgen, wodurch eine Vereinfachung des Betriebes erreicht wird.It is also known to use push buttons to adjust the traffic wave, To use grinders, turntables or the like, which are used for generating or receiving Modify or change the oscillation circuits associated with the electrical waves accordingly. vote. According to the present invention, however, should be a transmission or Receiving circuits for hot cathode tubes that do not have any external circuitry feedback work between the grid and the anode circuit, an inevitable connection between the two Wandering away from home should be provided. The operation of this compulsory connection can also at the same time as your wave taker selector, which simplifies the Operation is achieved.
