Description

Entladungsgefäß zum Zwecke der Gleichrichtung, Verstärkung oder Erzeugung von Schwingungen Gegenstand der vorliegenden Erfindung ist ein Entladungsgefäß, das zum Zweck der Gleichrichtung, der Verstärkung oder der Erzeugung von Schwingungen verwendet wird. Als Kathode für dieses Entladungsgefäß wird eine Elektrode verwendet, die unter dem Einfluß einer äußeren Bestrahlung oder äußeren Erhitzung Elektronen aussendet. Man hat bei Elektronenröhren mit derartigen indirekt beeinflußten Kathoden beispielsweise einen Teil der Glaswand selbst als Kathode benutzt, der mit einem emittierenden Überzug versehen wird. Für die Heizung wird an der Außenwand des Vakuumgefäßes ein Heizkörper angebracht, z. B. einige Windungen Widerstandsdraht gelegt. Als Kathodenmaterial verwendet man zweckmäßig Oxyde oder Überzüge von Alkalimetall.Discharge vessel for the purpose of rectification, amplification or generation of vibrations The subject of the present invention is a discharge vessel, that for the purpose of rectification, amplification or the generation of vibrations is used. An electrode is used as the cathode for this discharge vessel, the electrons under the influence of external irradiation or external heating sends out. In electron tubes with such indirectly influenced cathodes for example, part of the glass wall itself is used as a cathode, which is connected to a emitting coating is provided. For the heating is on the outer wall of the vacuum vessel a radiator attached, e.g. B. put a few turns of resistance wire. As cathode material it is advisable to use oxides or coatings of alkali metal.

Vorliegender Erfindung gemäß wird das Glas selber mit solchen Zusätzen versehen, daß es durch Erwärmen zum Emittieren gebracht werden kann, wobei dem Glase eine solche Leitfähigkeit zu geben ist, daß der Emissionsstrom durch das Glas seinen Rückweg findet.According to the present invention, the glass itself is made with such additives provided that it can be made to emit by heating, the glass such a conductivity is to be given that the emission current is through the glass Finds the way back.

In den Abbildungen ist schematisch eine Röhre gemäß der Erfindung dargestellt.In the figures is schematically a tube according to the invention shown.

K ist der Teil der Glaswand des Entladungsgefäßes E, der als Kathode wirkt. G ist das Gitter, A die Anode. Um den Teil K des Gefäßes ist ein Heizdraht H gewickelt.K is that part of the glass wall of the discharge vessel E that acts as the cathode works. G is the grid, A is the anode. There is a heating wire around part K of the vessel H wrapped.

Während Abb. z im wesentlichen eine Röhrenanordnung darstellt, bei welcher ein plattenförmiges Gitter vorgesehen ist, stellt Abb. a eine Röhrenanordnung dar, bei der ein zylindrisches Gitter geschlossen die plattenförmige Anode umgibt. Die Kathode ist in diesem Falle die gesamte Gefäßwand der Röhre mit Ausnahme der zu isolierenden Teile am Röhrenfuße.While Fig. Z essentially shows a tube arrangement, at which a plate-shaped grid is provided, Fig. a shows a tube arrangement represents, in which a cylindrical grid closed surrounds the plate-shaped anode. The cathode in this case is the entire vessel wall of the tube with the exception of the parts to be insulated at the tube base.
