Abstract: 415,140. Wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and RUST, N. M., 109, London Road, Chelmsford. Feb. 23, 1933, No. 5585. [Class 40 (v).] A modulation system comprises a bridge of four resistances R1-R4, Fig. 1, with the carrier applied across one diagonal and the modulated output taken from the other diagonal ; the signal being applied to the control electrode T3 of one or more negative-resistance valves V connected in series or in parallel with one or more of the bridge arms. Fig. 1 shows a single dynatron valve connected across the resistance R4, the carrier being derived from a tuned circuit C, L, and the output taken to a valve amplifier VI. A condenser C3 is used to balance the capacity introduced by the valve V In Fig. 6, a negative resistance valve N is arranged in series with each of the resistance arms R4, R1 and the signal circuit T3, T4 is connected in phase opposition to their respective control grids. If one of the valves N is arranged in shunt to the corresponding resistance, the signal is applied in phase agreement to the grids (Fig. 7, not shown). A negative resistance valve N may be associated with each resistance arm R1-R4, Fig. 8, one phase of the signal being applied in parallel to a series-connected and a shunt-connected pair, the other phase to the other pair. The bridge is normally unbalanced so that the carrier is not suppressed, and the signal varies the degree of unbalance ; maximum signal may bring the bridge into balance, giving 100 per cent modulation. Specification 399,616 is referred to.
