Abstract
1394552 Agitating liquids AUTOTROL CORP 7 May 1973 [10 May 1972] 21695/73 Heading B1C A rotor, 20, 21 providing support for an aerobic bacterial sluice in the treatment of waste water comprises a stack of discs 28a, 28b formed to provide radial passages 30, 36 and generally concentric passages (31, Fig. 3 not shown) defined by corrugations 33a-e and extending between and opening into the radial passages. As shown the formed discs are stacked back to back; they may be of polystyrene or polyethylene, vacuum formed and solvent or sonic welded. Each disc may consist of a group of sectors (see Figs. 6 and 7 not shown), the # junctions between sectors in adjacent discs being staggered. In another arrangement (see Figs. 8-10, not shown) the formed discs may alternate with flat discs, the formed discs having cut-outs which provide the radial passages; and in a modification (see Figs. 11 and 12, not shown) the formed sheets are continuous and the flat sheets have cutouts. In an embodiment which avoids vacuum forming, Fig. 15, the formed discs are replaced by trapezoidal sectors 83 cut from a continuous extruded strip (84, Fig. 13 not shown).
