  • Device for granulometric analysis of particles in fluids
    Patent number: 4226532
    Abstract: According to the invention, the device for granulometric analysis of particles contained in fluids comprises a feeding channel and a receiving channel intended for passage of a fluid under investigation. The two channels communicate with each other through a nozzle. The ratio between the diameters of the nozzle and the receiving channel is in the range of 1/4 to 1/7. The receiving channel is provided with transparent windows for passage of a light flux emitted by a lighting means through the fluid in that channel. The device further includes a light-sensitive means to receive light reflected from particles contained in the fluid.

  • Device for introducing samples into fluid analyzer
    Patent number: 4206650
    Abstract: According to the invention, the device for introducing samples into an analyzer of an apparatus for granulometric analysis of particles contained in fluids comprises a funnel whose outlet is connected to a channel communicating with a supply channel of an analyzer. Immediately downstream of the funnel, the channel has a horizontal portion of a length roughly equal to 3 to 5 channel diameters. Downstream of the horizontal portion there is a vertical portion whose diameter first gradually increases until it is 4 to 6 times greater than its initial value and is then gradually reduced to the initial value.

  • Apparatus for calibrating instruments for granulometric recording
    Patent number: 4193288
    Abstract: An apparatus for producing a fluid flow containing particles of a given size is intended to calibrate the instruments for granulometric recording of particles in fluids. The apparatus comprises a chamber having an inlet port and an outlet duct to communicate with the inlet of the instrument being calibrated, and having a feeding duct to feed the chamber with reference particles. At least one portion of the chamber near the outlet duct is implemented as a horizontally oriented transparent cylinder in which a transparent duct is disposed coaxially with the cylinder. One end portion of the transparent duct tapers to a diametrical size which is commensurate with the maximum diameter of the reference particles. An inspection means to monitor the size of the reference particles is disposed above this end portion.
