Definitions

  • FIG. 1 shows diagrammatically examples of apparatus embodying the invention and. for use, for exam le, in testing the washin s of fibrous materials (wood pulp, paper pu p or the like).
  • Fig. 1 shows the apparatus insectiozand Fi 2 is a front view.
  • the front wall f and rear wall g of the box a are formed of glass sheets; behind therear wall g there is a source of light )5. with a screen, so that the illuminated material can be clearly examined at Wall v

  • -wn.nnor. emaux;nssrcnoa 'ro-m the front rate of flow so that the individual particles of the material and anyvimpurities can be clearly seen.
  • apparatus such as sizing; or grinding mills, through which there is a constant flow and where a continuous control of 'the propertiesof the material is required, the
  • apparatus is simply inserted in the eflluent.
  • the suspension is in constant motion (for example washin apparatus, bleaching machines or the li e)
  • one portion of the liquid 0- containing the matter in suspension can be branched ofi to the apparatus and the control device inserted in the branch pipe.
  • the funnel-shaped enlargement shown in the drawing'at the inlet to the box d has the advantage that the velocity of flow is reduced, or the pressure lessened, and this flow easily controlled.
  • suspension for. a better estimation of the properties, a standard example of the particular suspension can be rovided within. or without the illuminated eld of observation?
  • the suspension may be illuminated indirectly by providing'the interior of the box traversed by the suspension with a reflecting rear wall.
  • the direction of flow which in the example shown is from below upwards can obviously be in other directions, for example in horizontal or inclined or (particularly in treating very heavy substances) from above downwards.
  • Apparatus for viewing the presence and v nature of solid matter in suspension in a liquid in motion comprising a vessel having its front'and back walls spaced apart a distance less than the distance 2 between its side walls and having an outlet at one end, a chamber having one of its ends in open communication with the other end of saidvessel and having an inlet'in its op 0- site end, the cross section of said chamber increasing from said inlet toward said vessel,
  • a source of light disposed outside the vessel and sheetsof transparent material formin the front and rear walls of said vessel an disposed opposite said source.
