It will be seen that the present invention provides a condenser of small size and of extremely cheap construction comparable in price and compactness to the ordinary paper condenser and far superior to it in its greater capacity, low losses, long life, and self-healing qualities. The condenser, as shown, provides for simple attachment to any radio receiver or similar apparatus with the necessity of making only one connection. The condenser is particularly adaptable to quantity production methods because it comprises only two major parts, namely, the cathode which -is in itself the container, and the anode which non-uniformities of operation.
What is claimed is:
1. An electrolytic condenser comprising a film ing anode, a container forming a cathode, means for supporting the anode within the container, an upstanding boss "adapted to project through a panel and having a vent, and securing means engaging with the boss for attaching the condenser to the panel and protecting the vent.
2. An electrolytic condenser comprising a filming anode having-an integral base, a container forming a cathode and enclosed by the base of the anode, a boss upstanding from the container and having a vent passage, a vent diaphragm, and securing means engaging with the boss and enclosing the diaphragm.
3. An electrolytic condenser comprising a base of filming material, a hollow and generally cylindrical anode having circumferential corrugations formed integral with the base, a circular container having a reduced neck portion provided with a vent opening and sealed to the base at its lower end with the anode centrally disposed therein, and a liquid electrolyte within the container completely submerging the anode.
4. An electrolytic condenser comprising a base of filming material, a hollow and generally cylindrical anode having circumferential corrugations formed integral with the base, a circular container having a reduced neck portion provided with a vent opening and sealed to the base at its lower end with the anode centrally disposed therein, a liquid electrolyte within the container completely submerging the anode, and means for connecting the condenser to a support through the reduced neck portion.
