Elektrische Entladungsröhre.
Die Erfindung bezieht sich auf eine elektrische Entladungsröhre mit positiver Säulenentladung und solcher Gestalt, dass die Röhrenenden nebeneinanderliegen. Es hat sich gezeigt, dass, wenn an diesen
Röhrenenden ein gemeinsamer Sockel festgekittet wird, die Röhre beim Betrieb manchmal platzt. Man hat festgestellt, dass dies durch die während des Betriebes stattfindende Ausdehnung der Röhre herbeigeführt wird. Der Nachteil tritt denn auch in der Hauptsache bei Entladungsröhren auf, in denen die Entladung im Dampf eines schwer verdampfbaren Metalles, z. B. Natrium, Lithium, Magnesium, Zink, d. h. im Dampf von Metallen, erfolgt, deren Dampfdruck bei einer Temperatur von 2000 C nur einen Bruchteil eines Millimeters beträgt. Diese Entladungsröhren werden beim Betrieb auf eine hohe Temperatur erhitzt, wodurch das Glas einer erheblichen Ausdehnung ausgesetzt ist.
Der erwähnte Nachteil wird nun gemäss der Erfindung dadurch beseitigt, dass die Enden der Röhre mit einem Sockel versehen werden, der nur an einem der Röhrenenden starr befestigt ist. Es hat sich gezeigt, das hiedurch das Platzen der Röhre unter dem Einfluss der Wärmeausdehnung auf sehr einfache Weise vermieden werden kann.
Zweckmässig wird in dem oder den Stromzuführungsdrähten zwischen dem Sockel und dem nicht starr an dem Sockel befestigten Röhrenende eine Ausdehnungskrümmung angebracht, so dass bei der Ausdehnung der Röhre auch der oder diese Stromzuführungsdrähte keine unerwünschten mechanischen Spannungen veranlassen.
In der Zeichnung ist eine beispielsweise Ausführungsform des Gegenstandes nach der Erfindung dargestellt. Fig. 1 zeigt eine Entladungsröhre mit Sockel teilweise im Schnitt. Fig. 2 ist ein Querschnitt nach der Linie J7-J7 der Fig. 1.
In Fig. 1 ist eine Entladungsröhre 1 dargestellt, die U-förmig ausgebildet und an den beiden Enden mit einem Füsschen 2 ausgestattet ist, auf dem eine Glühkathode 3 und eine Anode 4 angeordnet sind.
Die Röhre enthält eine Menge Edelgas, z. B. Neon, unter einem Druck von einigem mm, sowie eine Menge Natrium, das beim Betriebe Natriumdampf entwickelt, so dass die Röhre dann ein intensives gelbes Licht ausstrahlt und eine positive Säulenentladung aufweist.
Die Röhre ist mit einem Sockel 5 ausgestattet, der aus Isolierstoff, z. B. Asbestzement, besteht.
Dieser Sockel weist an der Unterseite zwei zylindrische Aussparungen auf, in denen die Enden der Röhre angebracht sind. Das Ende 6 ist dabei mittels einer Kitt-oder Gipsmasse 7 starr an dem Sockel 5 befestigt, was beim Röhrenende 8 nicht der Fall ist. Zwischen diesem Röhrenende und dem Sockel 5 ist ein Spielraum von z. B, 1 mm vorgesehen.
Der Sockel ist als Bajonettsockel ausgebildet. Die beiden Kontakte 9 stehen mit den Elektroden in Verbindung, wobei jede Kathode 3 mit der sie umgebenden Anode 4 verbunden ist. Da jeder Elektrodensatz nur mit einem Stromzuführungsdraht versehen ist, können die Glühkathode 3 nicht durch einen besonderen Heizstrom geheizt werden, sondern es erfolgt die Heizung dieser Elektroden durch den Entladungsstrom selbst. Es wäre aber auch möglich, den Sockel mit einer solchen Anzahl Kontaktorgane zu versehen, dass besondere Heizströme durch die Glühkathoden hindurehgeführt werden können.

Electric discharge tube.
The invention relates to an electric discharge tube with positive columnar discharge and such a shape that the tube ends are adjacent to one another. It has been shown that when on this
Tube ends are cemented to a common base, the tube sometimes bursts during operation. It has been found that this is brought about by the expansion of the tube that takes place during operation. The disadvantage arises mainly in discharge tubes in which the discharge occurs in the vapor of a metal that is difficult to evaporate, e.g. B. sodium, lithium, magnesium, zinc, d. H. in the vapor of metals, the vapor pressure of which is only a fraction of a millimeter at a temperature of 2000 C. These discharge tubes are heated to a high temperature during operation, which causes the glass to undergo considerable expansion.
The above-mentioned disadvantage is now eliminated according to the invention in that the ends of the tube are provided with a base which is rigidly attached to only one of the tube ends. It has been shown that the bursting of the tube under the influence of thermal expansion can be avoided in a very simple manner.
An expansion curve is expediently made in the power supply wire or wires between the base and the tube end that is not rigidly attached to the base, so that when the tube is expanded, the power supply wire or wires do not cause any undesired mechanical stresses.
In the drawing, an example embodiment of the object according to the invention is shown. Fig. 1 shows a discharge tube with a base partially in section. FIG. 2 is a cross section taken along line J7-J7 of FIG. 1.
In Fig. 1, a discharge tube 1 is shown, which is U-shaped and is equipped at both ends with a foot 2 on which a hot cathode 3 and an anode 4 are arranged.
The tube contains a lot of noble gas, e.g. B. neon, under a pressure of a few mm, as well as a lot of sodium, which develops sodium vapor when operating, so that the tube then emits an intense yellow light and has a positive column discharge.
The tube is equipped with a base 5 made of insulating material, e.g. B. asbestos cement.
This base has two cylindrical recesses on the underside in which the ends of the tube are attached. The end 6 is rigidly attached to the base 5 by means of a cement or plaster mass 7, which is not the case with the tube end 8. Between this tube end and the base 5 there is a margin of, for. B, 1 mm provided.
The base is designed as a bayonet base. The two contacts 9 are connected to the electrodes, each cathode 3 being connected to the anode 4 surrounding it. Since each set of electrodes is only provided with one power supply wire, the hot cathode 3 cannot be heated by a special heating current, but these electrodes are heated by the discharge current itself. However, it would also be possible to provide the base with such a number of contact elements that special heating currents can be passed through the hot cathodes.
