Abstract: 907,028. Determining physical dimensions. COULTER ELECTRONICS Ltd. May 29, 1959 [Dec. 29, 1958], No. 18419/59. Class 37. A particle studying apparatus comprises an apertured vessel having a vitreous ceramic wall to which is fused an apertured wafer of highly heat-resistant material such that the two apertures are in alignment. The vessel, Fig. 2, comprises a glass tube 16 of, for example, borosilicate glass having a flattened wall 40 in which a hole 78 is formed by touching a heated glass stick on the wall long enough to adhere to it and pulling it away. The outer surface of the wall is then ground flat giving it a frosted appearance, and a sapphire wafer 76 having a small (e.g. 30-500 microns) aperture 42 is aligned with the aperture 78. The sapphire is then heated with a pointed flame until the glass softens and fuses with the bottom of the sapphire. The complete apparatus (Fig. 1) comprises the vessel 16, an outer glass vessel 18 and a branched glass member 24 which engages in a fluid-tight joint with the vessel 16. One branch 28 connects with a metering device 14, a second branch 30 fitted with a tap is used for flushing, and the third branch 34 also fitted with a tap, is connected to a source of vacuum. Electrodes 48, 50 are placed in the vessels 16, 18 and are connected to a detecting device 12 containing a cathode-ray oscilloscope and a counter to provide a means of measuring the change in resistance between electrodes as particles suspended in a fluid 44 pass through the gap, and also a means for counting the number of pulses produced in a predetermined time. In operation the vessel 16 is filled with a fluid (which may differ from that in the outer vessel) and the tap 36 is opened to connect the vacuum which draws a piston 58 up the arm 28. On closing the tap the piston moves down the tube under the influence of a weight 66 drawing fluid 44 into the inner vessel through the scanner orifice. The piston is connected to the weight by a cord passing over a pulley wheel 64, and as the wheel rotates a projection on it closes a counter start switch 70 and then, after a predetermined time interval the stop switch 72. Specifications 722,418, 865,069 and 903,156 are referred to.
