Abstract

1,200,208. Filter for sewage. KOEHLERDAYTON Inc. 14 Nov., 1967 [14 Nov., 1966], No. 51847/67. Heading B1D. [Also in Division El and E2] The w.c. pan (17) in a bus or aircraft discharges into a closed tank (11) from which the liquid content is drawn through a filter 56 by an internal pump 54 and recycled as flushing liquid to a manifold (38) in the pan (Fig. 1, not shown). The filter comprises a hollow plastics clup-like body with internal or external axial ribs 75 and circumferential, parallel sided slots machined through its vertical wall except for the ribs, and is cleaned by plastics combs 78 which move relatively thereto. In Figs. ,2, 3, 6, the filter has internal ribs and is rotated by a pinion. 72 engaging teeth 70 thereon, and combs 78 are fixed outside the filter. In Figs. 4, 5, 7 (not shown), the filter is fixed and has external ribs, and pinion 72 rotates the combs (115) on their annular support inside the filter. The combs may be moulded and machined like the filter, or may be built up of individual teeth and spacers. Spout (35) (Fig. 1) is hinged at (32) and may 'be pushed aside. An outlet valve (22) is fitted in tank (11).
