1376420 Particle analyzer system GENERAL SCIENCE CORP [15 May 19721 14500/74 Divided out of 1376419 Heading G1N The invention comprises a circuit arrangement for providing automatically a statistical correction for particles coincident in the aperture of a particle analyzing system, such as that described in the Specification 1376419. As shown in Fig. 3 a signal representing the number per unit volume from integrator (90) Fig. 1 (not shown) is applied to an exponential function generator zoo, having RBC and WBC settings controlled by switches 222, 224. Gates circuits are opened during the volume measuring time, so that oscillator 208 generates pulses which are added to the counter for that part of the time when the exponential signal exceeds a reference level as determined by comparator 208. The gates are controlled by an ON-OFF pulse from the volume measurement Fig. 1. |
