Abstract
988,799. Capacitors. RADYNE Ltd. Oct. 15, 1963 [Sept. 17, 1962], No. 35330/62. Heading H1M. [Also in Division H3] The output coupling coil 2 of radio frequency heating equipment (see Division H3) is provided with a screen formed as a capacitor consisting of three plates 3, 4, 5, Fig. 1. If solid dielectric is used between the plates, e.g. polythene film, the plates may be made of silver-plated copper. Alternatively, polytetrafluoroethylene or silicone rubber may be used as dielectric. In an alternative form the screen may be formed as coaxial cylinders or flattened tubes. In order to match the output capacitance to the load, the output circuit is provided with a series variable capacitance comprising plates 14, 17, Fig. 3, the plate 17 being pivoted at one end 20 to vary the capacitance. Plates 14, 13, 16 also form a fixed capacitance to earth.
