Abstract: A method and mechanism for adjusting/controlling the pitch of at least one blade of a wind turbine relative to a wind direction parallel to a longitudinal main shaft of the wind turbine use a mechanism with a motor for rotating drive wheels in the angle gear around a longitudinal blade shaft via drive wheels of an angle gear. The method and mechanism can stop the complete turning of a main shaft of a wind turbine having a motor to rotate a drive pinion in an angle gear via a drive wheel, the angle gear being meant to pitch at least one blade around a longitudinal axis.

Abstract: An offshore wind turbine is disclosed wherein the power transmission in the nacelle is cooled by means of a liquid conducted to the nacelle from the tower on which the nacelle is pivotally arranged around a vertical yawing axis. The liquid transfers heat to the seawater near the turbine which is used as a heat sink of low temperature and enormous heat capacity as compared to traditional air cooling. The liquid is conducted in a closed circuit and the cooling system may comprise more than one cooling circuit. The flow of cooling-liquid may be conducted between the tower and the nacelle through a heat transfer unit having a first part that is stationary with respect to the tower and a second part that is stationary with respect to the nacelle. The parts have at least one annular passageway for a liquid flow defined between abutting surfaces of the parts.

Abstract: A support or separation, especially a book-end consists of a resilient element (1) and a support element (2). The support or the separation achieves its function by, that the branch (5) of the resilient element, which engages the underside of the shelf and the upper branch (3), which the support element slides upon, is wedge shape, thereby one can adapt the support or separation to the thickness of the shelf by displacing the support element on the resilient element. Hereby is obtained a surface pressure between the parts, which results in, that the support is self-locking, and hereby is the function of the support or the separation obtained. The two holes in the support element are placed so, that by turning the support element upside down variations in adaption to the doubled thickness of the shelf can be obtained.
