Abstract: A drive system for tape transducer capstan drive control for synchronously controlling capstan drive over a wide speed range, the system being a phase locked loop which encompasses the motor, all drive components, and the capstan. The capstan drive to a tape record receives rotation from a capstan drive motor which also provides a rotational sense output. A control circuit receives the sense output as well as a selected reference frequency signal and processes the signals in accordance with selected binary control input thereby to generate the requisite drive voltage for energization of the capstan drive motor.

Abstract: Apparatus for presenting information to a group in attention in a manner whereby the rate of information presentation is variable with respect to the group as a whole; the apparatus consists of a reproducing device for generating both an information signal and a control tone for distribution to a plurality of informationreceiving stations. The distribution system provides for the reproduction of a series of predetermined amounts of information, each amount or serially occurring portion being terminated by a control tone which ceases reproduction and enables a listener response tally. Thereafter, each listener signifies readiness to continue by means of a switch closure, and after a predetermined number of such switch closures the reproducing device is restarted to generate the next segment of its information.

Abstract: Control circuitry for use with tape transducing apparatus which enables increased versatility of tape playback functions. The apparatus has the capability of automatic tape rewind, message recycle, endless message repeat, and other automatic functions valuable in playback of certain forms of music, advertising and the like. A tape motion sense circuit functions in response to sensing of tape drive motor supply voltage to monitor tape forward and rewind conditions for coactive operation with such as tape record control tone information, end of tape and other condition enablement to further control transducer head positioning.
