anlage erhält infolge der Dämpfungswirkung des Widerstandes 9'nur ganz allmählich ansteigend Strom, so dass die sämtlichen Glühkathoden geschützt sind.
Statt des Glühkathodeugleiehrichters 3 kann natürlich auch ein solcher ohne Glühkathode, beispielsweise ein Quecksilberdampfgleichrichter verwendet werden. Desgleichen kann statt des Widerstandes 9'auch ein Widerstand 9"im Anodenkreis 7 eingeschaltet sein. Bei Anschluss der Verstärker- anlage an ein Gleichstromnetz wird man den Widerstand 9"stets anwenden. In diesem Falle fällt der links von den Punkten A, B, a liegende Teil der Schaltanordnung fort. Statt dessen wird zwischen die genannten Punkte ein Spannungsteiler gelegt. Dann kann beim Einschalten der Heizstrom über die Punkte A, B, C sofort fliessen, während der Anodenstrom nur allmählich ansteigt.
Die vorstehend beschriebenen Anordnungen sind nur Beispiele. Der Erfindungsgegenstand kann sinngemäss auch auf andere Glühkathodenentladungsgefässe in anderer Schaltung übertragen werden, z. B. auf Gleichrichter mit mehr als zwei Anoden, Wechselrichter usw. Ferner ist er mit Vorteil für Glühkathoden-Sender-Röhren, insbesondere für hoch beanspruchte Senderöhren mit Wasserkühlung verwendbar.
PATENT-ANSPRÜCHE :
1. Anlasseinrichtung für Glühkathoden-Entladungsgefässe, dadurch gekennzeichnet, dass in den
Anodenstromkreis der Entladungsgefässe Anlasswiderstände mit negativem Temperaturkoeffizienten, vorzugsweise aus Urandioxyd, eingeschaltet sind.

As a result of the damping effect of the resistor 9 ', the system only receives a gradually increasing current so that all of the hot cathodes are protected.
Instead of the hot cathode rectifier 3, one without a hot cathode, for example a mercury vapor rectifier, can of course also be used. Likewise, instead of the resistor 9 ', a resistor 9 "can also be switched on in the anode circuit 7. When the amplifier system is connected to a direct current network, the resistor 9" will always be used. In this case, the part of the switching arrangement lying to the left of points A, B, a is omitted. Instead, a voltage divider is placed between the points mentioned. Then, when switching on, the heating current can flow immediately via points A, B, C, while the anode current only increases gradually.
The arrangements described above are only examples. The subject matter of the invention can analogously also be transferred to other hot cathode discharge vessels in a different circuit, e.g. B. to rectifiers with more than two anodes, inverters, etc. It is also used with advantage for hot cathode transmitter tubes, especially for highly stressed transmitter tubes with water cooling.
PATENT CLAIMS:
1. Starting device for hot cathode discharge vessels, characterized in that in the
The anode circuit of the discharge vessels, starting resistors with a negative temperature coefficient, preferably made of uranium dioxide, are switched on.
