Patent DE-19920504-A1 (DE)
Inventor: WOBBEN ALOYS
IPC: F03D7/02
Filed: 1999-05-05
Abstract: Wind turbines are generally provided with an active driving system for orienting them according to the wind direction. This driving system rotates the wind-turbine nacelle so that the rotor blades are oriented in the wind direction. The driving system used for this orientation generally consists of an azimuthal driving system which is arranged together with the corresponding azimuthal bearings between the top of the tower and the nacelle. In small-size wind turbines, an adjustable driving system is sufficient, while larger wind turbines are provided with a plurality of azimuthal driving systems. The purpose of the present invention is to improve the azimuthal driving system for wind turbines in order to create an azimuthal driving system having a simple structure, to ensure a regular load distribution for each azimuthal driving system and to avoid unwanted torque variation in individual driving systems. This invention essentially relates to a wind turbine comprising a nacelle having a rotor with at least one blade arranged therein, wherein said wind turbine also includes an unit for displacing the nacelle in order to place the rotor in a desired orientation in the wind direction. The driving member of this displacement unit consists of a three-phase asynchronous motor which is supplied with a three-phase current in order to displace the nacelle and which is partially or completely supplied with a direct current during the nacelle inactive period.

IPC: B02C19/22
Filed: 1999-05-29
Abstract: The conveyor spiral (26) has circumferential cutters (46), for pre-reduction in the size of the material being comminuted. Preferred features: The cutters are teeth (50) denticulating the carrier spiral. The end section (48) near the outlet is free of teeth. The spiral extends back to cover the feed channel (22) outlet.

Inventor: KRABBENHOEFT UWE-JENS
IPC: H04N1/60
Filed: 1999-09-29
Abstract: Disclosed is a method for producing a transformation in area of colour, whereby the colour values of a first printing process are converted to the colour values of a second printing process in such a way that the black structure of the first printing process is substantially transferred to the second printing process and the visual impression  of the printed colours in both printing processes are substantially the same. The colour reproduction qualities of the printing processes are characterised by color profiles which indicate a correspondence between the colour values dependent upon a device of the printing processes (CMYK) and the colour values of an area of colour which are independent of a device (LAB). The luminosity curves (L) are determined from these colour profiles according to the black printing inks (K) and the luminosity curves (LAB) are determined according to the coloured printing inks (CMY). Both luminosity curves are combined to obtain the desired transformation of said area of colour.
