Abstract

1468738 Filters A ELLILA 7 Oct 1974 [24 Oct 1973] 43355/74 Heading B1D The solids retained on frusto-conical sieve 1 are assisted in their movement towards outlet 3 by directing sprays of liquid from one or more rotating pipes 4 at an oblique angle to the sieve 1. The pipes may have round openings or slits or nozzles attached thereto.
