    Abstract: Apparatus which receives a train of electrical pulses from a particle analyzing device such as one which is operated in accordance with the Coulter principle, derives statistical hematological indices from such train of pulses, stores the same in suitable storage means, receives a second train of pulses and derives the same indices from the second train of pulses, and compares the two indices. A readout device provides the comparison information. In this manner indices from normal blood may be obtained and thereafter the same indices from unknown blood may be obtained and compared with the normal indices for diagnosis of pathology.

    Abstract: A particle study device wherein a non-diluted specific minute amount of fluid sample containing particles is ejected by an ejecting mechanism into a flow stream leading to a sensing zone in the particle study device. The ejecting mechanism includes a hollow body having a thermal expansion device mounted therein and a power supply circuit which supplies a predetermined amount of electrical energy to the thermal expansion device to raise the temperature of same a predetermined amount and cause the same to expand thereby to eject from the hollow body a specific amount of fluid sample having a volume displacement equal to the volume increase of the thermal expansion device. Preferably the hollow body is part of a syringe including a plunger. The syringe facilitates the picking up of fluid sample of which only a minute specific portion is ejected toward the sensing zone of the particle study device.

    Abstract: Disclosed is an improved method and apparatus for analyzing particles by the Coulter principle of employing an impedance responsive detecting aperture through which pass particles in suspension. Employed herein are a plurality of logically parallel detecting apertures, preferably of different microscopic sizes, each aperture feeding circuitry which is subdivided into a plurality of channels, each responsive to a different narrow subrange of particle size. By time and volume related elements, there is generated an output voltage which is proportional to particle volume per unit time over the entire particle system; hence, statistically valid data is available at all times during an analysis run, even in the event of a malfunctioning blockage of an aperture.

    Abstract: Method for determining the hemoglobin content of a sample by the photoelectric monitoring of a reference and the sample and the transducing thereof into a pair of electrical signals representative of the relative light transmission of the two media. The reference signal is applied to a store and, through comparison with the sample signal, an output signal having a duration directly proportional to the hemoglobin content is elicited. Also, apparatus for carrying out such method in which a capacitive storage circuit is charged proportionally to the reference light transmission through use of a monochromatic light and photocell and is discharged to an intermediate value dependent upon the transmission of the sample, the duration of such discharging being the desired output. Interposed in series between the photocell and the storage circuit is an operational amplifier a diode and a switch. The amplifier provides a voltage follower enabling the diode to be a precise comparator between the two signal levels. The time dependent output is taken from the anode side of the diode.
