120 cm high, provided with a high pressure-drop gas distributor to insure uniform gas flow. Below the distributor is a specially designed knife valve operated by a solenoid for quick gas shutoff. [Pg.248]

The carriage is provided with a slide rheostat which sends out a voltage proportional to the position of the carriage, to an xy-recorder which traces the subsidence curved simultaneously with the bed collapsing process. This same voltage is also fed to a microcomputer for data acquisition and on-line analysis. [Pg.249]

The entire determination, from gas shutoff to printout from the computer, rarely exceeds three to four minutes for normal solids. Also, since all measurements are taken by the instrument, they are not subject to personal error of observation. The size of a solids test sample is of the order of a kilogram or less. [Pg.250]
