Abstract

934,731. Circuit assemblies; capacitors. SOC. OREGA ELECTRONIQUE & MECANIQUE. June 1, 1961 [June 2, 1960], No. 19824/61. Class 37. [Also in Group XXXV] A tuned circuit device for the I.F. stage of a radio receiver comprises an inductance coil and a tuning capacitor, the latter comprising a strip 9 of dielectric material sandwiched between two conductive strips 8, 10 wound about a ferrite sleeve 1 which closes a frame 2 of carbonyl iron upon which is mounted a winding 3. The inductance of the device is adjusted by means of a screw (not shown) inserted in a threading 4 and a bottom plate 6, which carries leads 7, is secured to the base 5 of the frame 2. The dielectric strip 9 may be of polystyrene and the conductive strips 8, 10 of aluminium. The whole device may be enclosed in a easing to reduce radiation.
