PATENTAMT.PATENT OFFICE.
/ Bei Entladungsröhren nach Patent 254588 ist es für das gleichmäßige Arbeiten der Röhre wichtig, daß der Dampfdruck unveränderlich ist, da ja von diesem die Leitfähigkeit hauptsächlich abhängt./ In the case of discharge tubes according to patent 254588, the It is important to the tube that the vapor pressure is invariable, since it is from this that the conductivity is determined mainly depends.
Wenn sich nun, wie es in jener Patentschrift beschrieben ist, der Bodenkörper an der kältesten Stelle des Rohres befindet, im allgemeinen also eine Temperatur in der Nähe der Zimmertemperatur hat, so schwankt der Dampfdruck und damit die Stromstärke in der Röhre stark mit der Außentemperatur.If now, as described in that patent, the soil body to the coldest part of the pipe, so generally a temperature close to it which has room temperature, the vapor pressure and thus the current intensity fluctuates in the tube strongly with the outside temperature.
Diesem Nachteil hilft die vorliegende Erfindung dadurch ab, daß sie einen dampfbildenden Körper verwendet, der erst bei wesentlich höherer Temperatur als Zimmertemperatur den für den Betrieb erforderlichen Dampfdruck hat, der also von den Schwankungen der Zimmertemperatur praktisch unabhängig ist.The present invention remedies this disadvantage in that it produces a vapor Body used only at a much higher temperature than room temperature has the vapor pressure required for operation, i.e. that depends on the fluctuations the room temperature is practically independent.
Die erforderliche Temperatur kann dem Körper natürlich durch irgend eine beliebige Art der Heizung gegeben werden. Zweckmäßig läßt man ihm aber die nötige Wärme durch Leitung oder Strahlung von der glühenden Kathode zuführen.The required temperature can of course be given to the body by any Type of heating to be given. However, it is expedient to give him the necessary warmth supply by conduction or radiation from the glowing cathode.
Am geeignetsten für diesen Zweck ist ein Körper, bei dem Gleichgewicht zwischen Dampf und Bodenkörper herrscht, wenn der Dampf eine niedrigere Temperatur hat als der Bodenkörper; solche Körper sind z. B. Quecksilberamalgame. Bei diesen ist nicht mehr zu befürchten, daß der Dampf sich an kalten Stellen der Wandung kondensiert oder die Elektroden amalgamiert; bei sinkender Temperatur wird vielmehr der Quecksilberdampf wieder von dem Amalgam absorbiert.Most suitable for this purpose is a body with a balance between steam and bottom body prevails when the steam has a lower temperature than the bottom body; such bodies are e.g. B. Mercury amalgams. With these there is no longer any fear that the steam will get cold Places the wall condensed or the electrodes amalgamated; with falling temperature rather, the mercury vapor is absorbed again by the amalgam.
Die Zeichnung zeigt eine nach dieser Erfindung ausgeführte Röhre. In einem besonderen Ansatz A in der Nähe der glühenden Kathode K befindet sich das dampfliefernde Amalgam; seine Entfernung von der Kathode ist so bemessen, daß es im Betriebszustand der Röhre durch die Strahlung von der glühenden Kathode die Temperatur erhält, die sich als zweckmäßig herausgestellt hat.The drawing shows a tube made according to this invention. In a special approach A near the glowing cathode K there is the amalgam that supplies steam; its distance from the cathode is such that, when the tube is in operation, the radiation from the glowing cathode gives it the temperature which has been found to be expedient.
