Description

In unserem Patent 539 869 ist eine Kathodenröhre mit mehreren Elektroden beschrieben, die in ihrer Wirkungsweise einer Doppel- oder Mehrgitterröhre gleichkommt, und zwar ist das erreicht dadurch, daß Gitter oder Anode oder beide Elektroden Je aus mehreren Teilen bestehen und so in der Flugbahn der Elektronen liegen, daß, vom Glühfaden aus gerechnet, Teile des Gitters und der Anode miteinander abwechseln und daß sämtliche zwischen Kathode und dem äußersten Teil der Anode angeordneten Elektrodenteile durchbrochen ausgebildet sind. In dem" Hauptpatent ist eine Ausführungsform jje-In our patent 539 869 a cathode tube with several electrodes is described, which is equivalent to a double or multi-lattice tube in its mode of action, and that is achieved by the fact that lattice or anode or both electrodes each consist of several parts and so in the trajectory of the electrons are that, calculated from the filament, parts of the lattice and the Alternate anode with each other and that all between the cathode and the outermost one Part of the anode arranged electrode parts are perforated. By doing" The main patent is an embodiment of each

*5 «rfindungsgemäßen Röhre senkrecht zur Achse des Glühfadens dargestellt. Der Glühfaden, in den Abbildungen mit F bezeichnet, ist beispielsweise als linearer Leiter ausgebildet. Es ist im Prinzip selbstverständlich auch möglich, ihn V-förmig oder anders auszubilden. Wie aus der Abbildung ersichtlich, umgeben den Glühfaden F das Gitter G und die Anode A, und zwar sind beide Elektroden annähernd zylindrisch ausgebildet, und zwar so, daß ein Schnitt senkrecht zur Achse des Systems, also senkrecht zum Glühfaden, die Form der Abb. 1 und 2 zeigt. In der Abb. 1 ist eine Ausführungsform dargestellt, wo ein Teil der Anode dem Glühfaden am nächsten liegt. Es folgt dann ein Teil des Gitters und dann erst die Anode. H1 und H- sind die Haltestege, an welchen das Gitter und die Anode befestigt sind. Der verschiedene Abstand der einzelnen Teile des Gitters und der Anode infolge des spiralförmigen Quer-Schnitts wird erfindungsgemäß dadurch aufgeAvogen, daß an den Stellen des Gitters und der Anode, die durchbrochen ausgebildet sind, der Abstand der Gitterstege entsprechend vergrößert ist, so daß also nach allen Riehtungen radial vom Glühfaden aus der Durchgriff der Röhre konstant bleibt, um eine ungünstige Wirkungsweise zu vermeiden.* 5 «tube according to the invention shown perpendicular to the axis of the filament. The filament, labeled F in the figures, is designed as a linear conductor, for example. In principle, it is of course also possible to make it V-shaped or different. As can be seen from the figure, the filament F surrounds the grid G and the anode A, and both electrodes are approximately cylindrical in shape, in such a way that a section perpendicular to the axis of the system, i.e. perpendicular to the filament, has the shape of Fig. 1 and 2 shows. In Fig. 1 an embodiment is shown where part of the anode is closest to the filament. Part of the grid then follows, and only then does the anode. H 1 and H- are the holding bars to which the grid and the anode are attached. The different spacing between the individual parts of the grid and the anode as a result of the spiral cross-section is compensated according to the invention in that the spacing of the grid webs is increased accordingly at the points of the grid and the anode which are perforated, so that after all Direction radially from the filament from the penetration of the tube remains constant in order to avoid an unfavorable mode of operation.
