Abstract

974,665. Filter networks. MARCONI CO. Ltd. July 27, 1961 [Jan. 13, 1961], No. 27246/61. Heading H3U. [Also in Division H1R] A band-pass filter comprises a number of LC sections 9, 10, each section being screened from its neighbour by a non-magnetic conductive screen 13, the screen being connected to one electrode 12 of a capacitor 9 and the sections being coupled by the capacitance 15 which exists between an electrode 12 and the screen of the neighbouring section. The inductors 10 consist of windings on a glass fibre core 6. The capacitors 9 have a common tubular electrode 5 spaced from the outer electrodes 12 (also tubular) by a machined layer 11 of PTFE. The size of the gaps 16 determines the magnitude of the coupling capacitances 15. If necessary, these may be increased by providing each screen 13 with a tube which partly surrounds the tubular electrode 12 of the preceding section. Coaxial sockets 19, 20 are respectively attached to an end member 22 and a casing 21.
