The jeta of water impinge uponspraying saucei-s or trays placed witliin the tower directlybelow each of the nozzles. The trays have upturned,serrated edges which may be varied as to inclinatioDand height in order to vary the angle at which the sprayis projected from their upjier surfaces.—W. H. C.

The liquid to be filtered enters through the pipe, G,-and passes through the sand, E, which rests on the per-forated plate, D. The perforations in this plate havedomed covers, d, pierced with small holes. Below D,is a layer of pebbles, C, supported on the perforatedplate, B. After passing through the sand and pebbles,the liquid is discharged through the pipe, J. When itis necessary to cleanse the sand, the supply of wateris shut ofi by the tap, g, and clean wateris forced throughthe pipe. L, into the annular pipes, k, and the radia!pipes, /.-l ; the latter have perforations, M, closed bynon-return valves which open only by pressure fromwithin. At the same time the wedge-shaped agitatorblades, /. provided with pointed, wedge-shaped pro-jections, /I, are rotated by the shaft, F, so as to stir upthe sand with the washing water. The latter flowsaway through the pipe, N, carrying the impurities withit.—W. H. C. Filter for viscous liquids. L. Morane. Fr.
