Abstract

556,167. Coil-less resonators. KOLSTERBRANDES, Ltd., and CORFIELD, D. N. March 20, 1942, No. 3716. [Classes 40 (iii) and 40 (v)] A coil-less resonator comprises an outer chamber joined at one end to a centrally disposed tube the other end of which is electrically connected to the movable system of a condenser of the parallel vane type. The condenser is adjusted by means of a rod 3 passing along the tube.
