Abstract

423,274. Distributiag music &c. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, LUCAS, G. S. C., 75, Eastlands Road, and HALL, E. S., 16, Oval Road, both in Rugby. Dec. 11, 1933, No. 34828. [Class 40 (iv)] Direct current from a battery 4 is superimposed on a feeder line 3 so that an instrument 5 gives an indication of the number of loudspeakers 2 connected across the line. A condenser 6 byepasses the audio-frequencies. A variable impedance 7 across the line enables the operator to adjust the load as required.
