<p>1,245,172. Surface aerators. VIZGAZDALKODASI TUDOMANYOS KUTATO INTEZET. 4 March, 1969 [6 March, 1968], No. 11530/69. Heading B1C. A rotatable surface aerator 4 is attached by a bridge 3 to floats 2 and tied by members 6 to a fixed point such as a pile 7 in such a way as to permit of gyratory motion about the pile under the reaction forces generated by rotation of the aerator. These may be increased by mounting the aerator non- equidistantly between the floats as shown, and by a baffle (5, Fig. 2 not shown) on one side of the aerator. A second gyrating aerator 4a is linked to the first, and there may be a third aerator 4b. Reference has been directed by the Comptroller to Specification 1,016,342.</p> |
