  Verfahren zur Unterbrechung von leitenden Verbindungen in Vakuumröhren. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Die Anoden 7 und 8 der Systeme 2 und 3 sind durch eine Brücke 9-vorteilhaft aus Magnesium, beispielsweise aus einem Stück   Magnesiumband-in   der Weise miteinander verbunden, dass die Anode 7 mit dem Halter 10, die Anode 8 mit dem Halter 11 in leitender Verbindung   stellt, während zwischen   den Halter 10 und 11 das Metallband 9 angeordnet ist. Dieses Metallband weist ein   kreisförmiges-   durch Stanzen leicht   herstellbares - Loch 12   auf, so dass in den Metallenen 13 und 14 die Unterbrechung des Metalls erfolgen kann. 



   Ein Stück Glimmer 15 ist zwischen dem Metallband 9 einerseits und den drei Elektrodensystemen   2,   3 und 4 anderseits schirmähnlich angeordnet. 



   Während des Entgasen der Anoden ist die Verbindung der Anoden 2 und 3 untereinander nützlich ; soll sie jedoch nach Fertigstellung der Röhre wiederum getrennt werden, so wird um die Röhre eine wechselstromführende Spule gelegt. Nach kurzer Einwirkungszeit der Hochfrequenzströme ist das Metallband 9 an den Stellen 13 und 14 unterbrochen. Die Zerstäubung des Magnesiums hat im Gegensatz zu andern   Unterbrechungsmöglichkeiten   noch den besonderen Vorteil, dass dadurch die Röhre nicht verschlechtert wird, im Gegenteil, das Vakuum wird sogar verbessert. 



   Durch den Schirm 15 wird erreicht, dass beim Zerstäuben des Magnesiums keine metallischen Niederschläge auf den aus Isoliermaterial hergestellten Elektrodenträgern erfolgen. 



   Die Erfindung ist nicht auf die Herstellung von Unterbrechungen leitender Verbindungen selbst beschränkt. Es kann unter Umständen nützlich sein, Nichtleiter, die an einer Stelle eines Vakuumgefässes vorhanden sind, von dort zu entfernen. Dies kann ebenfalls durch die Erfindung geschehen, etwa in der Weise, dass der betreffende Nichtleiter durch metallische Halter, wie Magnesiumbänder, anfangs festgelegt wird, während man ihn nachher durch Wirbelstromverdampfung frei macht.

   The anodes 7 and 8 of the systems 2 and 3 are connected to one another by a bridge 9 - advantageously made of magnesium, for example from a piece of magnesium tape - in such a way that the anode 7 with the holder 10, the anode 8 with the holder 11 in conductive Connection establishes, while the metal band 9 is arranged between the holder 10 and 11. This metal band has a circular hole 12, which can be easily produced by punching, so that the metal can be interrupted in the metal ends 13 and 14.



   A piece of mica 15 is arranged like an umbrella between the metal strip 9 on the one hand and the three electrode systems 2, 3 and 4 on the other.



   During the degassing of the anodes, the connection of the anodes 2 and 3 to one another is useful; however, if it is to be separated again after the tube has been completed, an alternating current-carrying coil is placed around the tube. After a short exposure time to the high-frequency currents, the metal strip 9 is interrupted at points 13 and 14. In contrast to other interruption options, atomization of the magnesium has the particular advantage that it does not deteriorate the tube, on the contrary, the vacuum is even improved.



   The shield 15 ensures that when the magnesium is atomized, no metallic deposits occur on the electrode carriers made of insulating material.



   The invention is not restricted to the production of interruptions in conductive connections themselves. Under certain circumstances, it can be useful to remove non-conductors that are present at one point in a vacuum vessel. This can also be done by the invention, for example in such a way that the non-conductor in question is initially fixed by metallic holders, such as magnesium strips, while it is subsequently released by eddy current evaporation.

PATENT-ANSPRUCH : Verfahren zur Unterbrechung von leitenden Verbindungen im Inneren von Vakuumröhren, dadurch gekennzeichnet, dass die leitende Verbindung aus einem verdampfbaren oder im Vakuum zerstäubungsfähigen Material in Form eines mit zur Hervorrufung der nötigen Wirbelstromdichten in den belassenen Randteilen hinreichend grossen Löchern versehenen Bandes hergestellt und sodann durch Wirbelströme zur Zerstäubung oder Verdampfung gebracht wird. EMI2.1 PATENT CLAIM: Method for interrupting conductive connections inside vacuum tubes, characterized in that the conductive connection is made from a material that can be vaporized or atomized in a vacuum in the form of a band provided with holes that are sufficiently large to produce the necessary eddy current densities in the left edge parts, and then by eddy currents Atomization or evaporation is brought about.
