Abstract

631,255. Distributing radio programmes. BRITISH THOMSON-HOUSTON CO., Ltd., and MOIR, J. Jan. 30, 1947, No. 2928. [Class 40 (iv)] In a wired radio-distributing system, the primary of a line transformer for each subscriber's receiver is connected to the main feeder through equal impedances such that the total impedance as seen from the line is materially greater than the product of the feeder impedance and the number of subscribers to be supplied.
