Реферат: 3650. Stevens, G. A. Feb. 14 Direct gas-pressure apparatus.-Steam or compressed air supplied by a pipe a forces the matter to be treated up a pipe c to the filter-press A by means of an ejecting or injecting action. When the pressure in the filter approximates to that of the compressed gas, a valve a<1> is closed and the gas pressure is communicated to the filter through the valve d' and pipe d. When filtration has finished, the pressure is released by opening the tap e<1> of a waste pipe e. The arrangement is stated to be applicable in the treatment of such matters as iron oxides, white lead, ochres, China-clay, and sewage sludge.
