Description
Kathodenröhren als Relais und Verstärker von Wechselströmen sind bekannt; jedoch ist es infolge der starken Rückwirkung auf die Abstimmapparate nicht ohne weiteres, möglich, diese verstärkten Ströme zum Betätigen elekrischer Apparate, z. B. Morseschreiber, zu verwenden. Cathode tubes as relays and amplifiers of alternating currents are known; however is Due to the strong reaction on the voting machines, it is not easily possible these amplified currents to actuate electrical ones Apparatus, e.g. B. Morse code writer to use.
Die Selenkathodenröhre gemäß der Erfindung löst diese Aufgabe in 'der Weise, daß zwischen Anode und Gitter einer Kathodenröhre eine Selenzelle so eingebaut wird, daß sie von dem durch das Gitter regulierten Kathodenstrom getroffen wird, sie kann also selbst die Anode bilden.The selenium cathode tube according to the invention solves this problem in 'such that A selenium cell is installed between the anode and the grid of a cathode tube in such a way that it is hit by the cathode current regulated by the grid, so it can themselves form the anode.
Ihre beiden Pole sind aus der Röhre hinausgeführt und können z. B. mit einem mechanischen Relais verbunden sein.Your two poles are led out of the tube and can, for. B. with a mechanical Relay connected.
Da die Wirkung der unsichtbaren Strahlen auf die Selenzelle der des sichtbaren Lichtes ähnlich ist, verringern auftreffende Kathodenstrahlen den Widerstand der Zelle und können dadurch in bekannter Weise ein mechanisches Relais o. dgl. sowie die damit verbundenen elektrischen Apparate (Morseschreiber) betätigen. Since the effect of invisible rays on the selenium cell is that of visible light is similar, incident cathode rays reduce the resistance of the cell and can thereby in a known manner a mechanical relay o. The like. As well as the associated Operate electrical devices (Morse code recorder).
Abb. ι stellt eine Kathodenröhre dar, bei der die Kathode« in bekannter Weise zum Glühen gebracht wird und einerseits durch die Leitung b über den Empfangskreis mit dem Gitter c, anderseits durch die Leitung d über eine Hochspannungsquelle mit der Anode e in Verbindung steht. Bei hoher Spannung kann die Heizung fortfallen. Vor der Anode be-findet sich die Selenzelle f, deren beide PoleFig. 1 shows a cathode tube in which the cathode is made to glow in a known manner and is connected on the one hand to the grid c via the line b via the receiving circuit and on the other hand to the anode e via the line d via a high voltage source. If the voltage is high, the heating can be omitted. In front of the anode is the selenium cell f, both of its poles
ζ. B. über eine Lokalbatterie mit dem Relais g verbunden, sind.ζ. B. connected to the relay g via a local battery.
Die Röhre ist so geformt und ihre Wandung so geschwärzt, daß das Licht der Glühlampe die Selenzelle nicht treffen kann, wohi aber können die evtl. durch das Gitter tretenden Kathodenstrahlen sie treffen und beeinflussen. Um bei hohem Vakuum die Verdampfung des Selens zu vermeiden, kann die Zelle durch eineThe tube is shaped and its wall blackened so that the light from the incandescent lamp the selenium cell cannot hit, but where can they possibly pass through the grid Cathode rays hit and influence them. In order to prevent the evaporation of the The cell can avoid selenium through a
ίο feste, jedoch lichtempfindliche und lichtdurchlässige Schicht, z. B. eine fluoreszierende Glasplatte h, abgeschlossen werden.ίο solid, but light-sensitive and translucent layer, e.g. B. a fluorescent glass plate h, be completed.
Abb. 2 zeigt die gleiche Röhre, jedoch mit Ausbildung der Außenseite der einen metallischen Belegung der Zelle als Anode.Fig. 2 shows the same tube, but with the outside of one metallic tube Allocation of the cell as an anode.
Abb. 3 zeigt die Röhre in etwas anderer Form, mit Anordnung der Anode seitwärts der Selenzelle und Verwendung eines geschwärzten Spiegels i zum Reflektieren der Kathodenstrahlen. Fig. 3 shows the tube in a somewhat different form, with the anode arranged to the side of the selenium cell and the use of a blackened mirror i to reflect the cathode rays.
Abb. 4 zeigt die Röhre mit seitlicher Anordnung einer zylindrischen Anode und Verlegung der Zelle außerhalb des Vakuums hinter die fluoreszierende Abschlußwand h der Röhre. Der Spiegel i kann nötigenfalls bei k elektrisch geladen werden.Fig. 4 shows the tube with a cylindrical anode arranged on the side and the cell laid outside the vacuum behind the fluorescent end wall h of the tube. The mirror i can be electrically charged at k if necessary.
