Abstract: IMPROVED BELT DRIVE AND BELTS AND PULLEYS THEREFOR           ABSTRACT OF THE DISCLOSURE      A belt drive and belt and pulleys therefor in which a toothed power transmission belt operates in conjunction with toothed pulleys.  The dimensional relationship between the belt teeth and pulley teeth is such that in the longitudinal extent of the belt between the pulleys the height of the belt teeth is greater than the height of the pulley teeth or depth of the pulley grooves while as the belt travels around the pulleys the extreme outwardly facing portions or outer extremities of the belt teeth contact the bottom of the pulley grooves and at the same time the belt teeth are compressed to reduce their height so that the extreme radially outwardly facing portions or outer extremities of the pulley teeth come in contact with the bottoms of the belt grooves.          The invention is particularly useful in a synchronous or positive drive system for increasing belt life by relieving stresses on the tensile member in the area between teeth of a positive drive power transmission belt.

Abstract: ABSTRACT OF THE DISCLOSURE           Circuitry for generating a virtually jitter free delay relative to a start pulse and for generating such delays over both integer and non-integer multiples of the time interval between timing pulses.  The circuitry includes delay circuitry and signal generating circuitry.  The delay circuitry is responsive to the start pulse and to the timing pulses for generating first and second signal edges.  The second signal edge occurs later in time than the first signal edge, and both signal edges occur following the start pulse and in timed relation to the timing pulses.  The signal generating circuitry is connected to the delay circuitry and has an output for generating an output signal which includes a timing cycle of known duration.  The signal generating circuitry is responsive to the start pulse for initiating the timing cycle, the first signal edge for interrupting the timing cycle, and the second signal edge for reinitiating the timing cycle.  The output signal begins in timed relation to the start pulse and terminates in timed relation to the end of the timing cycle following interruption.
