Abstract

209,435. Naamlooze Vennootschap Instituut voor Aero-en Hydro-Dynamiek, (Assignees of Ackeret, J., and Betz, A.). Jan. 8, 1923, [Convention date]. Drawings to Specification. Blades, vanes, &c.-The blades or vanes of fastrunning water turbines are made hollow and formed with suction slots through which the water is drawn by suction pipes, the suction being produced by conducting a portion of the driving water through the main suction pipe, to which the suction apertures are connected.
