Abstract

485,618. Impedance networks. CORK, E. C., and PAWSEY, J. L. Nov. 18, 1936, No. 31604. [Class 40 (iii)] In a network, at least one reactance is tuned by virtue of the length of wire employed, and all the reactances are individually shielded, the shields 13, 14, 15 being connected together as by a junction box 15a to form a unitary structure. The invention is applied to a low-pass filter for eliminating very high frequencies and comprising a T-network with series inductances 9, 10 tuned by their length and a shunt series tuned circuit 11, 12. Specifications 442,537 and 453,842 are referred to.
