Abstract

390,026. Wireless receiving - sets MARCONI'S WIRELESS TELEGRAPE CO., Ltd., Marconi House, Strand, London -(Assignees of Roberts, W. van B. ; 155 Hodge Road, Princeton, New Jersey, U.S.A. June 13, 1932,'No. 16709. Convention date, June 12, 1931. [Classes 40 (iii) and 40 (v).: A wireless receiver 12 is completely shielded, a low-pass filter 8, 9 is inserted in the energy supply leads 4 passing through the receiver screen, the receiver is coupled. to its aerial A through a screened filter 15, and the screening for the latter and the receiver is continuous. The filter 8, 9 is screened, and a screened lowpass filter 10 is also inserted in the leads 3 to the loud-speaker. The filter 15 consists of a plurality of sections 14. The band-pass filter shown may be replaced by a filter consisting of circuits tuned to the desired frequency and rejector circuits tuned to interfering frequencies Fig. 2 (not shown). High-frequency is thus prevented from penetrating to the receiver except by the discriminating filter 15. Specification 375,737 is referred to.
