Abstract
1470926 Aerating liquids MACHINEFABRIEK W HUBERT & CO BV 13 Aug 1975 [29 Aug 1974] 33772/75 Heading B1C A rotatable surface aerator has a boss 1, 2 carrying a plurality of radial blades 3 interconnected by a ring 7, the blades extending at 10 beyond the ring and having lower edges which extend perpendicularly to the rotational axis at 5 and thereafter upwardly, and upper edges which extend outwardly and upwardly the adjacent blade portion 9 being bent in the intended direction of rotation. Preferably the angle of the portion 9 is 30‹ to 60‹ to the plane of the blade, and a part of the lower edge of the blade may be bent in the same sense. As shown the ring 7 is upwardly convex but it may be planar or frusto-conical, or diminished to a slip.
