DEFINITION

Classification: 352/16

(under subclass 15) Subject matter which comprises a control means actuated by the sound record to produce a signal which controls the time rate of operation of the picture.

(1) Note. The subject matter in this generic subclass includes, for example, systems which the control is by a physical configuration of the sound record such as notches or speed change of the sound record as opposed to control by a recorded signal as in the indented subclass 17.
