Description

Es ist ein elektrischer Kondensator konstanter Kapazität zur Kompensation des Temperaturkoeffizienten z. B. von Schwingungskreisen bekannt, bei dem ein mitAußenbelag versehenes Rohr aus zwei oder mehreren Rohrabschnitten mit verschiedener Wandstärke und untereinander verschiedenen Dielektrizitätskonstanten und verschiedenen Temperatutkoeffizientem, aber gleichem Innendurchmesser besteht. In diesem Rohr ist -ein vorzugsweise lkeramisches Rohr, das mit einem Metallbelag versehen ist, verschiebbar angeordnet.It is an electrical capacitor of constant capacity for compensation the temperature coefficient z. B. known from oscillation circles, in which a mitAußenbelag provided pipe made of two or more pipe sections with different wall thicknesses and different dielectric constants and different temperature coefficients, but the same inside diameter exists. In this tube there is a preferably oil-ceramic Tube, which is provided with a metal coating, arranged displaceably.

BeiAnwendung in einem Schwingungskreis dient die mit der verschiebbaren Elektrode abgreifbare HF-Spannung zur Gitterneutralisation einer Triode.When used in an oscillation circuit, the one with the movable one is used Electrode tapped HF voltage for grid neutralization of a triode.

Es wurde nun gefunden, .daß es vorteilhaft ist, das aus mehreren Rohrabschnitten mit verschiedenen Dieiektrizitätskonstantenbestehende Rohr als halbierte Hohlzylinder aus unterschiedlichem izeramiscJhem Werkstoff auszubilden und die Halbzylinder an .ihren planen Längsflächen miteinander zu verbinden, z. B. zusammenzuglasieren oder zu verlöten.It has now been found that it is advantageous to consist of several pipe sections with different dielectric constants existing tube as halved hollow cylinder from different izeramiscJhem material and the half-cylinder .to connect their flat longitudinal surfaces with one another, e.g. B. glaze together or to solder.

In der Zeichnung sind zweü Ausführungsformen der Erfindung beispielsweise dargestellt.In the drawing, two embodiments of the invention are for example shown.

Abb. i zeigt einen Kondensator in Draufsicht; Abb. 2 zeigt den Kondensator in scJhaub'i@ldlieher Ansicht; Abb.3 ist eine andere Ausführungsform in Draufsicht.Fig. I shows a capacitor in plan view; Fig. 2 shows the capacitor in scJhaub'i @ ldlieher view; Fig.3 is another embodiment in plan view.

Zwei Halbzylinder 7 und 8 gemäß Abb. i bzw. io und i i gemäß Abb. 3 bestehen aus verschiedenem keramischem Werkstoff mit unterschiedlichen Dielektrizitätskonstanten. Die Hal@bzylirider sind an ihren Schnittflächen gleichlaufend zur Längsachse miteinander verbunden, z. B. zusammenglasiert oder verlötet.Two half cylinders 7 and 8 according to Fig. I or io and i i according to Fig. 3 consist of different ceramic materials with different dielectric constants. The Hal @ bzylirider are at their cut surfaces parallel to the longitudinal axis with each other connected, e.g. B. glazed together or soldered.

Bei der Ausführungsform der Abb. i und 3 wird ein glatter Außenzylinder. gebildet, der einen festen Innenbelag 13 besitzt. Mit 9 ist eine um die Längsachse drehbare Halbzylinderelektrode bezeichnet.In the embodiment of Figs. I and 3, a smooth outer cylinder is used. formed, which has a fixed inner lining 13 . With a semi-cylindrical electrode rotatable about the longitudinal axis is designated.

Bei der Ausführungsform der Abb.3 ist ein Außenbelag 1q. vorgesehen und eine drehbare Halbzylinderelektrode 12 im glatten Innenraum. Die drehbaren Halbzylinderelektroden 9 bzw. 12 ermöglichen je nach ihrer Einstellung die Änderung des Temperaturkoeffizienten.In the embodiment of Figure 3, an outer covering 1q. intended and a rotatable half-cylinder electrode 12 in the smooth interior. The rotating half-cylinder electrodes 9 or 12 allow the temperature coefficient to be changed depending on their setting.
