Abstract

320,628. Baird, J. L., and Television, Ltd. April 16, 1928. Divided on 320,639, [Class 40 (iii), Telegraphs, Electric]. Centrifugal governors.-For maintaining constant speed of an electric motor driving television apparatus, the governor 12 is loaded with a spring so as to render it unstable, and with an additional weak spring 16 arranged to come into action at the desired speed of running. The governor operates a two-way switch 20 controlling means for accelerating and retarding the motor.
