Abstract: The invention relates to a wind turbine that extends about a mast on a bearing ring, and comprises two rotors furnished with rotor blades; wherein the rotors are rotatably disposed on the bearing ring and on either side of the mast and a wind deflector plate that extends partially around the mast and is rotatably disposed on the bearing ring, wherein the wind deflector plate is oriented so that the wind blowing towards the mast is diverted towards the rotor blades.

Abstract: A wind generator with a rotor which rotates in the horizontal direction and has a plurality of rotor blades, wherein the rotor blades are surrounded in some areas by a fairing, the fairing being aligned according to the wind direction so that the rotor blades which are running in the opposite direction to the wind direction are always protected. The wind generator is provided preferably for subsequent fixing on already existing masts wherein the device has an annular bearing ring on which the rotor rotates on bearings, the bearing ring extending around the mast and being fixed by connecting braces on the mast.

Abstract: Battery farming equipment suitable for breeding, rearing or fattening purposes has a multi-tiered structure comprising movable perforated flooring for the livestock, and separate plates beneath the flooring for collecting excrement. The flooring extends wholly across the equipment to allow adequate space expansion for the growing livestock and is movable to facilitate a through-flow farming process.
