Der Gegenstand der Erfindung betrilit eine weitere Ausbildung der Empiangsanordnung für drahtlose Telegraphie nach Patent 3325S1. Nach dem Hauptpatent wird ein Kathodenstrahlenrelaiä mit Hilfe eines an der Empfangsstelle erzeugten Wechselstromes derart beeinflußt, daß die aufgefangene Hochfrequenzenergic gleichzeitig umgeformt und verstärkt wird. Die Intensitätsänderungen dieses Wechselstromes können dann mit den bekannten Mitteln, z. B. durch ein gewöhnliches Telephon, beobachtet werden. Man hört dann entsprechend den ankommenden Signalen den Ton der lokalen Wechselstromquelle.The subject matter of the invention relates to a further development of the empire arrangement for wireless telegraphy according to patent 3325S1. According to the main patent is a cathode ray relay influenced with the help of an alternating current generated at the receiving point, that the captured high-frequency energy is transformed and amplified at the same time. the Changes in the intensity of this alternating current can then be carried out using known means, e.g. B. by an ordinary telephone. You then hear accordingly to the incoming Signals the sound of the local AC power source. Eine besondere wirksame Anordnung besteht nach vorliegender Erfindung darin, daß als Kathodenstrahlenrelais eine Röhre mit zwei Anoden und zwei Verstärkungsgittern verwendet wird, wobei das eine Gitter von der ankommenden Hochfrequenz und das andere von dem Wechselstrom beeinflußt wird.A particularly effective arrangement according to the present invention is that as Cathode ray relay uses a tube with two anodes and two reinforcing grids with one grating from the incoming radio frequency and the other from the alternating current is affected. Auf der Zeichnung ist ein Ausführungsbeispiel liner derartigen Anordnung dargestellt.In the drawing, an embodiment of such an arrangement is shown. ι bedeutet das Kathodenstrahlrelais mit zwei Anoden 2, 3 und zwei Hilfsanodcn (Verstärkungsdm-ri 4 und 5.

"6 is the hot cathode, which can be heated by the battery 7. 8 is a battery, which is located between the anode 2 and the cathode υ , while the battery u is arranged between the cathode ft and the anode 3: The voltage of the battery η is chosen to be somewhat higher than that of the battery ^. By means of the coil ΐυ. which couples with the coil 11 of the antenna 12 «i .-t, the intercepted high-frequency oscillations can be fed to the tube 1, where the resistance for the path 6-5-3 increases ν The electrons flowing to the anode. 3 are partially repelled and there is a lower resistance on the \ 6- 4-2. In FIG. 4, these electron ions are now fed in by a local alternating current of low frequency, which comes from the machine 14 via the transformer 13, and the effect is amplified in a known V. Since the electron current, fluctuations follow immediately, Incoming signals can be heard on the telephone 15a, always in the tone of the frequency of the machine 14.
