Description
- Glühkathodengleichrichterröhre Es besteht häufig das Bedürfnis, einem Glühkathodengleichrichter gleichzeitig mehrere Ströme verschiedener Spannung und Stärke zu entnehmen, z. B. zum Laden der zum Betrieb eines Radioapparates nötigen Sammlerbatterien, wobei die aus ein bis drei Zellen bestehende Heizbatterie mit starkem, die aus mindestens 3o Zellen bestehende Anodenbatterie mit schwachem Strom zu laden ist. Um dies zu ermöglichen, besteht der Gleichrichter aus einem Transformator mit mehreren sekundären Wicklungen verschiedener Spannung und aus einer Entladungsröhre mit mehreren Anoden und einer Glühkathode. ° Gegenstand der Erfindung ist eine hierfür besonders geeignete Entladungsröhre, deren Ansicht die Abbildung zeigt.- Hot cathode rectifier tube There is often a need to a hot cathode rectifier, several currents of different voltages at the same time and strength to be taken, e.g. B. to load the necessary to operate a radio set Collector batteries, with the heating battery consisting of one to three cells strong, the anode battery consisting of at least 3o cells with weak current is to be loaded. To make this possible, the rectifier consists of a transformer with several secondary windings of different voltages and from a discharge tube with several anodes and a hot cathode. ° The subject of the invention is one for this particularly suitable discharge tube, the view of which is shown in the illustration.
Die Glühkathode b in Form einer Spirale ist umgeben von der größeren Anode c, aus zweimal rechtwinklig gebogenem Blech mit etwas verschmälertem Boden. Die kleinere Anode c2 ist ein nur mit seiner Spitze aus einem Quarzrohr ragender Draht. Zwischen dieser Spitze und der Kathode liegt der Boden der größeren Anode cl, durch welchen die kleinere an der höheren Spannung liegende Anode c2 gegen die Kathode b geschirmt ist, so daß ein Stromübergang in der ungewollten Richtung reit Sicherheit vermieden wird. Außerdem sind die Elektroden von einfacher Gestaltung; so daß die Herstellungskosten der Röhre gering sind. Es sind zwar schon Entladungsröhren bekannt, bei welchen die eine Anode durch die andere gegen die Kathode abgeschirmt ist, doch zeigen diese Röhren- eine viel verwickeltere Bauart und besitzen auch nicht eine aus einem mit Ausnahme seiner Spitze isolierten Draht bestehende Anode, durch deren Verwendung die Röhre nach der Erfindung besonders einfach geworden ist. Eine solche Anode war zwar an sich bekannt, aber nicht in Verbindung mit einer zweiten Anode.The hot cathode b in the form of a spiral is surrounded by the larger one Anode c, made of sheet metal bent twice at right angles with a slightly narrowed bottom. The smaller anode c2 is one that protrudes from a quartz tube only with its tip Wire. The bottom of the larger anode lies between this tip and the cathode cl, through which the smaller anode c2 lying at the higher voltage against the Cathode b is shielded so that a current transfer rides in the unwanted direction Security is avoided. In addition, the electrodes are simple in design; so that the manufacturing cost of the tube is low. They are already discharge tubes known in which one anode is shielded from the cathode by the other is, but these tubes show and also have a much more intricate design not an anode consisting of a wire which is insulated except for its tip, through the use of which the tube according to the invention has become particularly simple. Such an anode was known per se, but not in connection with a second one Anode.
