Abstract

1,240,466. Press filter. ENGLISH CLAYS LOVERING POCHIN & CO. Ltd. 1 July, 1968, No. 7373/71. Divided out of 1,240,465. Heading B1D. The disclosure corresponds to that relating to Figs. 1 to 5 of Specification 1,240,465 and the claims relate to the operating process, emphasising the scouring of the lower part of the filter element by the ingoing slurry and the generally equal densities of slurry and hydralic pressing fluid.
