Abstract: 1475636 Measuring angular speed electrically R WILKE and H KORTHAUS 24 April 1975 [24 April 1974] 17016/75 Addition to 1418138 Heading G1N The invention is an improvement on Pat. 1418138 wherein the angular speed of a shaft is measured by a tachogenerator of specified construction producing a sine wave voltage of proportional frequency which is fed to a series resonant circuit to produce a voltage which falls at excessive high and low speeds to cut off power from the motor driving the shaft. In the present invention the spacing between the rotor and stator of the tachogenerator G, Fig. 1, is allowed a greater tolerance, and the signal A.C. voltage is clipped by Zener diodes D1, D2 and transistor T 1 to produce a constant sinusoidal voltage across resonant circuit LR, CR, RR when the angular speed of the test shaft is consistent with the resonant frequency. The voltage across resistor RR is rectified and fed to a Schmitt trigger Tr, whose output is 0 when the shaft speed differs from normal by a quantity pre-set on potentiometer P1, to de-energize a relay RL and switch off the power supply. Resonant circuits R8, C8 and R9, C9 and transistor T2 bypass relay RL during starting.
