Abstract

919,422. Measuring electrically. B.P.L. (INSTRUMENTS) Ltd. Nov. 7, 1960, No. 38135/60. Class 40 (1). The engine R.P.M. meter of Fig. 1 of Specification 919,421 is modified to permit the pulses to be derived from the primary circuit of the ignition coil rather than the secondary circuit. The pulses from the engine contact breaker being applied to terminal B and filtered by the 33 K. resistor and 0.05 ÁF capacitor, rectified by the diode, and applied via a 300 pf capacitor to the monostable trigger and metering circuit of Specification 919,421.
