Abstract

400,913. Rotary fans. JAUCH, L., 30, Rue Desaix, Paris. Jan. 29, 1932, No. 2732. Void [Abridged as open to inspection under Sect. 91 of the Acts, March 13, 1932]. [Class 110 (i).] The blades of screw propellers, paddlewheels, fans and other surfaces moving relatively to a fluid are provided with ducts in the vicinity of areas liable to cavitation whereby a fluid may be conducted to destroy this phenomenon. The blade P of a paddlewheel has a cross duct c leading from the working face A to a position B on the following face at a greater radial distance. Alternatively, a less inclined duct D may be used and it is then of frusto-conical -longitudinal section. In another modification, the fluid may be supplied from the hollow axes 0 along a duct R. As applied to a screw propeller blade, an inclined main channel C with an inlet at A on the driving face has transverse branches t<1>, t<2> leading to orifices b<1>, b<2> on the rear face and having cross sections which alter the pressure of the discharged fluid. With longitudinal main channels and transverse branches, the fluid is supplied under pressure from a passage in the hub. The channels may be constituted by tubes embedded in the cast metal.
