Description
Glimmlichtventilröhre Die Erfindung betrifft eine praktische Ausgestaltung von Glimmlichtven üMhren. EI-Endungsgemäß wird,die Anode bzw. werden die Anoden. der Röhre derart gestaltet, daß durch Vergrößerung des an der Entladung beteiligten Teiles.der Anode deren Wärmekapazität erhöht wird. Die so konstruierten Anoden sind gegenüber dem bisher Bekannten gegen Zerstörungseinflüsse, insbesondere .gegen Erwärmung, äußerst widerstandsfähig.Glow valve tube The invention relates to a practical embodiment of glow light veins. According to EI, the anode or the anodes. The tube is designed in such a way that by enlarging that involved in the discharge Teiles.der anode whose heat capacity is increased. The anodes so constructed are against the previously known against destructive influences, especially against warming, extremely resistant.
Die Abbildungen zeigen ein Ausführungsbeispiel der Erfindung. Der obere Teil des Anodendrahtes ist von einer Spirale L von schwer schmelzbarem Materialumgeben. Als Material für idlese Spirale wird zweckmäßigerweise Molybd@ändraht von 0,3 mm Dicke gewählt, während der Draht, um den sie gewickelt ist, aus Eisen von o,8 mm Dicke besteht. Die Entladung geht von der Molybdändrahtspitze aus. Während -des Betriebes schweißt sich das Melybdän mit :dem Eisen zusammen, so .daß eine vorzügliche Wärmeableitung vom. dem Molybdändraht nach dem Eisendraht hin stattfindet. Damit die Spirale von dem Eisendraht nicht abgleitet, wird sie an dem oberen Ende mit einer Flachzange ;gequetscht, wobei gleichzeitig ein leichter Druck der Spiralen nach dem Steatitkörper s erfolgt, so daß dieser auf das Glasröhrchen g fest aufgepreßt wind. Durch dieses Flachdrücken des oberen Teils der Spirale einerseits und die Verschweißung während des Betriebes andererseits ward bewirkt; daß sowohl die Spirale wie auch ider -Steatitkörper und die Glasfüßchen fest miteinander zusammenhängen.The figures show an embodiment of the invention. The upper part of the anode wire is surrounded by a spiral L of difficult-to-melt material. Molybdenum wire 0.3 mm thick is expediently chosen as the material for the ideal spiral, while the wire around which it is wound consists of iron 0.8 mm thick. The discharge originates from the molybdenum wire tip. During operation, the Melybdän welds itself together with: the iron, so that excellent heat dissipation from the. the molybdenum wire takes place towards the iron wire. So that the spiral does not slip off the iron wire, it is squeezed at the upper end with flat-nose pliers; at the same time, the spirals are pressed gently towards the steatite body s so that it is pressed firmly onto the glass tube g. This flattening of the upper part of the spiral on the one hand and the welding during operation on the other hand was effected; that both the spiral as well as the steatite body and the glass feet are firmly connected to one another.
