Description
Es ist bereits vorgeschlagen worden, zur Verstärkung oder Erzeugung ungedämpfter elektrischer Schwingungen eine Kathodenröhre mit einem Glühdraht, einem Gitter und einer Anode zu verwenden. Das Gitter war dabei über eine Selbstinduktion an eine Stromquelle gelegt, während die Anode über eine zweite Selbstinduktion, zu der ein Kondensator im Nebenschluß geschaltet war, ebenfalls an die Stromquelle angeschlossen war, wobei die beiden Selbstinduktionen so angeordnet waren, daß sie sich gegenseitig beeinflußten.It has already been suggested to amplify or produce undamped electrical vibrations a cathode tube with a filament, a grid and to use an anode. The grid was connected to a self-induction Current source placed while the anode has a second self-induction to which a capacitor was shunted, was also connected to the power source, the two self-inductions so were arranged to influence one another.
Nach der Erfindung wird von der Verwendung eines Gitters im Innern der Röhre abgesehen, und! die Röhre wird in ihrem Querschnitt zwischen dem Glühdraht und der Anode zu einer Einschnürung verengt, durch welche die Entladung verläuft. Außerhalb der Röhre und um die Einschnürung herum wird ein Metallbelag aus Draht, oder Blech angeordnet, der, wie früher das Gitter, über eine Selbstinduktion an die Stromquelle angeschlossen ist.According to the invention of the use apart from a grid inside the tube, and! the tube is in its cross-section narrowed to a constriction between the filament and the anode which the discharge proceeds. Outside the tube and around the neck a metal covering made of wire or sheet metal is arranged, which, like earlier the grid, over a self-induction is connected to the power source.
Weiter werden nach der Erfindung auf beiden Seiten der Einschnürung die Pole eines Elektromagneten angeordnet, durch dessen Feld der Strom auf den gewünschten Betrag eingestellt werden kann.Furthermore, according to the invention, the poles are one on both sides of the constriction Electromagnet arranged through whose field the current to the desired amount can be adjusted.
Eine Kathodenröhre nach der Erfindung ist in der Zeichnung beispielsweise dargestellt A cathode tube according to the invention is shown in the drawing, for example
V ist eine Kathodenröhre mit einem Glühdraht F und einer Anode H. Die Röhre ist in der Mitte eingeschnürt, und um den eingeschnürten Teil ist ein Belag aus Draht oder Blech vS" angeordnet, der an einen Hochspannungserzeuger G über eine Selbstinduktion R1 zu der im Nebenschluß ein Kondensator K liegt, angeschlossen ist. Ji1, M2 sind die Pole eines Elektromagneten. V is a cathode tube with a filament F and an anode H. The tube is constricted in the middle, and a covering made of wire or sheet metal vS "is arranged around the constricted part, which is connected to a high-voltage generator G via a self-induction R 1 to the im A capacitor K is connected by the shunt. Ji 1 , M 2 are the poles of an electromagnet.
Die Anode H ist in der üblichen Weise mit dem Schwingungserzeuger über eine durch einen Kondensator K1 kurzgeschlossene Selbstinduktion R1 verbunden, und die die Selbstinduktion R, R1 enthaltenen Kreise sind so angeordnet, daß sie sich gegenseitig· beeinflussen. The anode H is connected in the usual way with the vibration generator over a short-circuited by a capacitor K 1 self-induction R 1, and the circles the self-induction R, R 1 contained are arranged so that they mutually · influence.
