摘要： 968,494. Counting particles. W. H. COULTER. Aug. 4, 1960 [Aug. 19, 1959], No. 13476/64. Divided out of 968, 491. Drawings to Specification. Heading G1N. The disclosure is identical with that of Specifications 968,491, 968,492 and 968,493, but the claims are directed to apparatus in which the pulses produced by the detecting means pass to a threshold producing means which has a power supply in common with the current source. Specification 722,418 also is referred to.

摘要： A curve tracer of two variables respectively represented on axes of variables Y and X on a recording rack, capable of being removed at a speed depending upon the first of the said variables, said tracer comprising a first regulation loop having a first movable organ, the removal of which is regulated by the variations of the second of the said variables, a second regulation loop having a second movable organ, allowing to trace a curve on the said recording rack, a scale transformation device, mechanically coupled with the first said movable organ and having a second recording rack on which is traced a scale transformation curve representing for each value to be transformed of the second variable, represented on the axis of X, a transformed value represented on the axis of Y, and detector means mounted in the second said regulation loop and adapted so as to be able to move along the axis of Y of the curve of the said second recording rack, the movement of the second movable organ being regulated by the movement of the detector means.

摘要： A method and apparatus for correcting a particle pulse count subject to coincidence error is disclosed wherein particle pulses, developed in response to passage of particles in a particulate system through a sensing zone, are counted for a predetermined period of time. The predetermined period of time is increased or extended in response to each pulse counted by a time increment that is a function of a characteristic of the counted pulse, such as the pulse width, duration, or amplitude. The total additional time period allows the counting of additional particle pulses such that the total count at the end of the extended time period is an error corrected count for the number of particles detected in the predetermined time period.
