Abstract

320,909. Baird, J. L., and Television, Ltd. April 25, 1928. Divided on 320,639. Television.-A television receiver and a gramophone 50 are geared to a single motor 14 through separate clutches 16, 24 so that either or both may be driven. The clutch 16 drives an exploring disc 8 adjacent to a lightsource 6 electrically connected to the television apparatus, and the clutch 24 controls the gramophone gearing. An electric pick-up device 66 is added to the gramophone. The sight record or sight-and-sound record described in Specification 289,104 may be used on the turntable 48, the record picture being reproduced by the disc 8 and light-source 6, and the modulated current from the pick-up device being amplified in transit by the amplifier 2.
