Description
Die Erfindung betrifft ein gas- oder dampfgefülltes elektrisches Entladungsgefäß mit Steuerelektrode. Der Zweck der Erfindung ist eine solche Ausbildung des Rohres, daß die Gesamtanordnung vereinfacht und verbessert wird. Erfindungsgemäß enthält ein gas- oder dampfgefülltes elektrisches Entladungsrohr mit Gittersteuerung eine Gleichrichberstrecke, welche zur Erzeugung einer festen Gleichspannung (Gittervorspannüng) für das Steuergitter dient. Diese Anordnung -ist besonders dann vorteilhaft, -wenn eine der Hauptelektroden des Gefäßes gleichzeitig die eine Elektrode der Gleichrichterstrecke bildet.The invention relates to a gas or vapor-filled electrical discharge vessel with control electrode. The purpose of the invention is such a design of the tube, that the overall arrangement is simplified and improved. According to the invention contains a gas or vapor filled electric discharge tube with grid control one Rectifier section, which is used to generate a fixed DC voltage (grid bias) is used for the control grid. This arrangement -is particularly advantageous -when one of the main electrodes of the vessel is also one of the electrodes of the rectifier path forms.
An Hand der Figur läßt sich dies deutlich zeigen. In dieser ist i ein steuerbares Entladungsgefäß mit Metallwand, die, aus zwei miteinander längs Flanschen verschweißten Teileng und 3 besteht. Zwischen die Flansche ist gleichzeitig das Steuergitter 6 eingeschweißt. Die Anode 5 ist mittels eines ringförmigen Körpers d. aus Glas oder glasähnlichem Werkstoff in den Wandungsteil2 eingeschmolzen. Die Glühkathode 7 sitzt innerhalb eines Wärmeschutzschirmes, 8, der einerseits mit dem einen Kathodenende, andererseits mit dem Haltestab 9 verbunden ist. Durch eine öftnung io ragt in den vom Schirm 8 umschlossenen Raum das Pumpröhrchen i i hinein; dieses bildet mit seinem einen Ende die Anode der Hilfsentladungsstrecke, die zur Erzeugung der Gittervorspannung dient. Die hierzu notwendige Wechselspannung liefert der Transformator 13, der über die beschriebene Gleichrichterstrecke den Kondensator 1q. ständig derart auflädt, das an dem Gitter stets eine negative Vorspannung liegt.This can be clearly shown on the basis of the figure. In this i a controllable discharge vessel with a metal wall, which, from two to each other, lengthways Flanges welded parts tight and 3 consists. Between the flanges is simultaneous the control grid 6 welded in. The anode 5 is by means of an annular body d. Made of glass or glass-like material melted into the wall part 2. the Incandescent cathode 7 sits within a heat shield, 8, on the one hand with the one cathode end, on the other hand, is connected to the holding rod 9. Through an opening io the pump tube i i protrudes into the space enclosed by the screen 8; this forms with one end the anode of the auxiliary discharge path, which is used to generate serves to prestress the grid. The transformer supplies the AC voltage required for this 13, the capacitor 1q via the rectifier path described. constantly like that charges, which is always a negative bias on the grid.
Die Anordnung gestattet besonders bei dem erläuterten Ausführungsbeispiel, auf das die Erfindung natürlich nicht beschränkt ist, große Vereinfachungen in der Schaltung, da keinerlei äußere Gleichspannungsquelle erforderlich ist. Trotzdem ist der Aufbau des Gefäßes selbst denkbar einfach; es werden lauter Teile zur Bildung der Gleichrichterstrecke verwendet, die ohnedies vorhanden sein müssen. Die Zahl der durch die Glaspfropfeneinschmelzung 12 hindurchtretenden Stäbe wird durch die Gleichrichterstrecke nicht erhöht, da das Pumpröhrchen als Anode dieser Strecke verwendet wird.The arrangement allows, particularly in the illustrated embodiment, to which the invention is of course not limited, great simplifications in the Circuit, since no external DC voltage source is required. Nevertheless the structure of the vessel itself is very simple; there are lots of parts for education the rectifier path, which must be present anyway. The number of the rods passing through the glass plug seal 12 is through the Rectifier path not increased, since the pump tube acts as the anode of this path is used.
