Title: Improved means for driving television or other apparatus at a predetermined speed
IPC: H04N5/04
Filed: 1927-06-07
Abstract: 301,847. Baird, J. L., and Baird Television Development Co., Ltd. June 7, 1927. Constant speed control systems.-For driving television or other rotary apparatus at a predetermined speed, a direct-current motor 20 is automatically controlled by a rotary contact device resembling a commutator with two long segments 28, 30 and a short tapered intermediate segment 32, the whole being driven by the motor 20. A rotary brush 36 driven by a constant speed master motor 34 remains in contact with the segment 32 so long as the speed of the motor 20 is equal to that of the master motor. If it lags or leads, the brush moves into contact with one of the segments 28, 30 which short-circuit resistances 50, 52 in the armature and field circuits respectively of the motor 20. Axial adjustment of the brush 36 increases or diminishes the delicacy of the speed-control.
