Abstract

1402400 Surface aerators SIMON-HARTLEY Ltd 8 May 1974 [9 May 1973] 22068/73 Heading BIC A rotary surface aerator comprises a circular disc 10 adapted to be rotated about its vertical axis, a plurality of angularly spaced blades 15 secured to the underside of the disc, each blade having a flange-like formation 16 on its lower edge extending on both sides of the blade for at least part of its length from its outer end and a further flange-like formation 17 on at least one side at a position spaced above the lower edge of the blade the further flange formation 17 extending from the inner end of the blade towards the outer end thereof. The flange 17 may define the upper edge of the blade 15 thereby providing a generally triangular gap between the upper edge of the blade the disc 10 and a central annular boss 12.
