The gas entei-s the cylindrical apparatus throughA, and deposits most of the liquid dm-ing itspa&sage through the large rest chamber, It then follows an S-shaped path and passesthrough nozzle-like perforations in tlie l>afflo-plates, E. The latter are tixeU between the plates,E, E2, the whole forming a chamber, which canbe withdrawn through an opening at the side ofthe outer casing. The gas escapes through theupper opening, H.—W. H.

CiKCULAB blocks of compressed pulp arranged inlayers are separated by plates having circularcorrugations ; the plates carry outer cyUndricalportions which unite to form the casing, and innercylindrical tubes which form a discontinuouscentral passage. Liquid entering by the annularspace between the and the blocks passesradially inwards over the corrugated plates, fromwhich it is directed by baffles on to the filter blocks,the filtered liquid passing from the blocks into thecentral passage.—W.
