Abstract: In a wind power plant having wind surfaces which are moved by air currents and coupled to a generator and are guided in longitudinal frames so as to be staggered one behind the other and are pivotally connected to lateral pulling devices and supported by endless lateral circulation rails, wherein the plant is mounted on a rotatable support plate, an arrangement and construction are provided in which, simultaneously, the wind surfaces are approximately perpendicular in the upper run of the pulling device and horizontal in the lower run and a number of wind surfaces at both ends of the longitudinal frame are in the reverse position. An additional horizontal guide strut may be disposed in the top region of each wind surface, the outwardly projecting ends of which guide strut engage an outer guide bar which, having a larger diameter, is secured to the longitudinal frame at a specific distance from the inner guide groove.

Abstract: In a power transmission plant having pressure surfaces for utilizing the natural flow gradient of water and wind quantities, a plurality of identical parallel conduits are provided which are open at the upper end and each have a rectangular cross-section, wherein two rectangular pressure plates--acting as drive members--are disposed in each conduit so as to be displaceable in a straight line in the direction of flow, said pressure plates being connected to a main shaft and extending in cross-sectional planes of the conduit. Such a plant permits the kinetic energy of turbulent flows to be used for harnessing power, whereby in each conduit a pressure plate, which is displaced in the lower portion of the cross-section by the fluid flow, drives the main shaft, while the other pressure plate moves back into its starting position in the upper portion of the cross-section of the conduit in order to then pass into the lower portion and into the flow.
