Abstract

442,501. Wireless signalling. BRUNI, R., 36, Via XX Settembre, Genoa, Italy. May 8, 1934, No. 13835. Void [Abridged as open to inspection under Sect. 91 of the Acts, Nov. 12, 1934]. Drawings to Specification. [Class 40 (v)] Relates to systems in which a carrier wave is modulated by audio-frequency-modulated currents of intermediate frequency as described in Specification 436,937 and comprises a heterodyne receiver in which the local oscillator and beat frequency circuits are ganged so as to enable the received intermediate frequency to produce a suitable beat frequency for feeding to the second detector. The arrangement may be applied to the disturbance-removing circuits described in Specification 379,305. The Specification does not permit of satisfactory abridgment.
