Abstract

375,265. Gramophones. MAZZA, COUNT G., 7, Lungarno Guicciardini, and ANTINORI, MARQUIS G., 3, Lungarno Torrigiani, both in Florence, Italy. Dec. 16, 1930, No. 37905. Convention date, Dec. 21, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] A gramophone adapted for reproduction by means of an electric pickup is driven by a spring motor a which also drives two dynamos d,d<1>. These dynamos d, d<1> supply current to energize a valve-amplifier e by which the currents produced in the circuit of the. electric pick-up are amplified and then fed to a loud-speaker f.
