  • Patent number: 4075462
    Abstract: A particle analyzer system which operates on-line, real-time and is adaptable to use in process control systems wherein the analysis provides a basis for control of the process. Images of particles are focused onto an array of light sensitive electronic elements. The resulting light pattern is translated into digital data which is retrievably stored in a memory. Analysis of the data by digital logic yields information as to particle counts, size, shape and other physical characteristics. Interim storage in the light sensitive array itself is provided which allows data accumulation using short duration stroboscopic illumination.

  • Patent number: 4063233
    Abstract: Three-dimensional images are produced within a transparent cathode-ray tube by directing a plurality of electron beams into a cloud of phosphorescent particles and causing the beams to intersect at a point within the cloud. Each individual beam's current is maintained at less than the threshold of luminescence of the particles but the combined currents may be caused to exceed that threshold by a controlled amount thereby producing light spots of variable brightness at the beam intersection point, which point may be directed into any part of the volume of the cloud. The particle cloud is produced by a high-gradient electric field pump. Use of the pump for particle cloud production in such applications as beam testing is also described.
