    Blocld : ondensator für. Radioempfaagsanlagen.   



   Bisher wurden als Dielektrikum bei Blockkondensatoren für Radioempfangsanlagen entweder   Schichten aus verschiedenem Material (Wachspapier, Ölpapier, Glimmer usw. ) verwendet oder   wurde das Dielektrikum durch Distanzierung der Kondensatorplatten aus Luftschichten gebildet. Die erstgenannten dielektrischen Schichten bilden einerseits keinen absoluten Isolator, wodurch sich grosse Hysteresisverluste ergeben, und ermöglichen anderseits durch den Kriechweg einen unbeabsichtigten Nebenschluss, daher in beiden Fällen starke Dämpfungsverluste. 



   Kondensatoren mit Luftdielektrikum haben wohl keine Hysteresisverluste, arbeiten also dämpfungsfrei, haben aber dadurch, dass speziell bei höheren Kapazitätswerten die Abmessungen solcher Kondensatoren zu gross werden und die Herstellungskosten wegen der besonderen Präzision einen hohen Verkaufspreis bedingen, zu grosse Nachteile, als dass ihre allgemeine Verwendung in Frage käme. 



   Diese Nachteile werden nach vorliegender Erfindung dadurch beseitigt, dass die dielektrischen Schichten aus unhygroskopischen Isolierplatten bestehen, die mit gitterförmigen Durchbrechungen versehen sind, so dass ein Luftkondensator mit Isolationsschicht entsteht, bei welchem wegen der besonders günstigen   Oberi1 chenisolation   (3000 Megohm) auch der Kriechstrom nicht in Betracht kommt, wodurch ein vollkommen dämpfungsfreies Arbeiten gewährleistet wird. 



   In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt u. zw. zeigt : Fig. 1 den Kondensator in Ansicht und Fig. 2 in Daraufsicht bei abgehobener Deckplatte. 



   In der Zeichnung bezeichnet a,   d die   obere bzw. untere Deckplatte, b die Kondensatorplatten, c die Gitterplatten, cl Isolationskappen für die. Schrauben.

    Blocld: ondensator for. Radio reception systems.



   Up to now, either layers of different materials (wax paper, oil paper, mica etc.) have been used as the dielectric in block capacitors for radio reception systems or the dielectric has been formed by spacing the capacitor plates from layers of air. The first-mentioned dielectric layers on the one hand do not form an absolute insulator, which results in large hysteresis losses, and on the other hand, due to the creepage distance, allow an unintentional shunt, therefore in both cases strong attenuation losses.



   Capacitors with an air dielectric do not have any hysteresis losses, i.e. work without attenuation, but because the dimensions of such capacitors become too large, especially at higher capacitance values, and the manufacturing costs result in a high sales price due to the particular precision, they have disadvantages that are too great for their general use in Question would come.



   According to the present invention, these disadvantages are eliminated in that the dielectric layers consist of unhygroscopic insulating plates which are provided with grid-shaped openings, so that an air capacitor with an insulating layer is created, in which, due to the particularly favorable surface insulation (3000 megohms), the leakage current does not occur It comes into consideration, whereby a completely damping-free work is guaranteed.



   In the drawing, an example embodiment of the invention is shown u. Between shows: FIG. 1 the capacitor in a view and FIG. 2 in a plan view with the cover plate lifted off.



   In the drawing, a, d denotes the upper and lower cover plate, b the capacitor plates, c the grid plates, cl insulation caps for the. Screws.
