1,158,481. Capacitors; spark gaps. GLOBEUNION Inc. 4 Aug., 1966 [5 Aug., 1965], No. 34951/66. Heading H1M and H1X. A component for use in electrical circuits comprises separate conductive members on an insulating supporting body and provided with leads, an air gap extending through the supporting body between the conductive members so that the shortest path between them is through air. As shown, a capacitor comprises electrodes 14, 16 deposited on one face of a steatite disc co-operating with a single electrode (18) on the opposite face (Fig. 3, not shown) and a spark gap for over-voltage protection is provided by slot 24. The arrangement may be encapsulated, except for the spark gap with e.g. phenolformaldehyde resin. Parallel resistance may be incorporated by local doping of the steatite or by interconnecting the electrodes with resistive paint. |
