Abstract: Lens connector for optical through-connection of light guides, which comprises two lens connector halves whose frontal faces face one another. The lens connector half (1) comprises a coupling housing provided with an internal space open at the front and rear of the coupling housing and with an optical system housed in the front-most portion of the internal space. The end of the light guide is fastened in the rearmost portion of the internal space (22). In the one lens connector half the light beam emanating from the guide fastened therein is widened by the optical system (24) and in the other lens connector half the received light beam is focused, by the optical system housed therein, onto the light guide associated therewith.

Abstract: Wind turbine for generating electrical energy by means of wind energy, comprising a turbine rotor which can be mounted on a mast and is rotatable about a rotor shaft with one or more rotor blades, and a generator equipped with rotor and stator. The generator is a sector machine of the asynchronous type, the stator of which has one or more discrete stator sectors, and the rotor of which is in a continuous, uninterrupted annular form and is directly coupled to--and has the same angular speed as--the turbine rotor. The one or more discrete stator sectors extend only opposite a small part of the annular generator rotor, of which the rotary movement is always in one direction. Each discrete stator sector comprises two stator halves which are fixed on the legs of a U-shaped holder mounted on the mast and define an air gap between them. Each stator half contains a plate stack with slits for the coil windings, each individual plate of which is a single plate which is a circular segment shape.
