Abstract

341,152. Maintaining equal speeds of motors. McCORMACK, W. E., 12, Charing Cross Road, London. Oct. 30, 1929, No. 32927. [Class 38 (iii).] In order to synchronize a kinematograph machine with a sound recording o r reproducing apparatus, the circuit of the motor M driving such machine includes a resistance R<1> which is continuously varied by a governor G driven from the machine itself and not from the motor driving the machine. Additional synchronizing means is provided by a second circuit shunted across a fixed resistance R<3> in the main circuit, the second circuit being periodically opened and closed in known manner by contacts Tc, Pc provided on discs T, P driven respectively by the gramophone turntable and the kinematograph machine. Before starting up, a resistance R<2> is set by hand to suit the speed at which it is desired to record or project the picture. The motor M may be speeded up by operating a switch S to exclude all resistance from the circuit.
