Abstract

519,506. Impedance networks. GENERAL ELECTRIC CO., Ltd., and BLOCH, A. Nov. 7, 1938, No. 32220. [Class 40 (iii)] [Also in Group XXXV] A low-pass filter comprises a helical coil 4 connected between the unearthed input and output terminals 7, 8, and one or more conductors, which may comprise split metallic sleeves, 1, 6, extending along but not completely surrounding the coil and connected to the earthed input and output terminals 9, 10 so as to form in conjunction with the coil the capacity elements of the filter. The inner sleeve 1, stiffened if necessary by a core of dielectric material, serves as a former on which the coil is wound. A powdered magnetic core may be provided to increase the inductance. Specification 453,538 is referred to.
