if the output voltage is reduced to between +3.9 and +8.2
pulses and sequence timing pulses is determined by the
volts dc, it turns off the rotation logic, disengages the
time taken to again pass the thresholds of CR10 and
sequential pulsing logic, and removes the gating pulse
CR9. If, when the gating pulse is supplied, the output
from the operational amplifier. When the operational
voltage of AR1 remains below +3.9 volts dc or above
amplifier is returned between the thresholds of CR10 and
+8.2 volts dc (below or
CR9 by a gating pulse, the pulse rate of the gating
