  • Method and an automatic device for analyzing variations in the transparency of a sample
    Patent number: 4109159
    Abstract: The method consists in generating an electrical signal B which is representative of the time-dependent variations in transparency, in generating a pulse at the initial instant of measurement, in carrying out an initial measurement of the slope of the curve at the beginning of the portion which has a steep slope, in comparing at predetermined instants the measured value of the initial slope with the slope of the curve which is representative of the signal B at these instants, in generating a second pulse when the measured slope becomes significantly different from the initial slope, and in measuring the time interval which elapses between the first and second pulses.
