Abstract: A pitch controlled wind turbine comprising a tower, a nacelle mounted on the tower, a hub mounted rotatably on the nacelle, and at least three wind turbine blades is disclosed. Each wind turbine blade extends between a root end connected to the hub via a pitch mechanism, and a tip end. The wind turbine further comprises at least three blade connecting members, each blade connecting member extending between a connection point on one wind turbine blade and a connection point on a neighboring wind turbine blade, the connection points being arranged at a distance from the root end and at a distance from the tip end of the wind turbine blade. The wind turbine further comprises at least three pre-tension members, each pre-tension member being connected to one of the blade connecting members and to a hub part, the pre-tension members thereby providing pre-tension in the blade connecting members.

Abstract: Disclosed is a guiding device (100) for receiving an elongated metal object being propelled by a first propulsion means and guiding it towards a second propulsion means. The first propulsion means and the second propulsion means being configured to propel the elongated metal object along a longitudinal axis (101), wherein the guiding device (100) comprise guiding means for receiving the elongated metal object and guiding it towards the second propulsion means. The guiding means (100) have a shape configured to guide the elongated metal object to a predetermined position along a first axis (103), the first axis (103) being perpendicular to the longitudinal axis (102), wherein the predetermined position is determined by the shape of the guiding means (100).

Abstract: The present invention relates to a method of controlling the aerodynamic load of a wind turbine's blades individually in such a way that the dynamic aerodynamic loads on the turbine are reduced and power production is optimised. In general the present invention will improve the overall stability of the turbine leading to reduce fatigue loads, reduced extreme loads during operation and reduced risk of blade-tower interaction. In particular preferred embodiment of the invention, flow properties are measured locally on the different blades or in front of the blades and from these measurements the pitch angle settings are changed, in other ways changing the aerodynamic properties, for the blades through a control unit.

Abstract: A steering system and a method for steering a vehicle, that has a wheel steering and an articulated steering. The steering system (1) has a steering unit (2), a first steering motor arrangement (7), which acts upon steered wheels, a second steering motor arrangement (8), which acts upon a converting kit, and a selection valve (6), which connects the steering unit (2) with either the first steering motor arrangement (7) or the second steering motor arrangement (8) in such a way that a steering will activate either the wheel steering or the articulated steering.

Abstract: A hydraulic steering system (1) for a vehicle with two steering motor arrangements, particularly an articulated vehicle with wheel steering, with a hydraulic steering unit (2) having a measuring motor section (22, 23), with a selection valve (6), which connects an outlet (L, R) of the steering unit (2) with either a first steering motor arrangement (7) that preferably acts upon steered wheels, or a second steering motor arrangement (9) that preferably acts upon a converting kit, and which is hydraulically operable via a pilot valve (14), and with a pump (4), which is connected with the steering unit (2) and the pilot valve (14). This permits the vehicle to be steerable in connection with an emergency.

Abstract: Disclosed herein is a method for hydraulic steering. The method includes supplying a steering unit with a controlled working pressure from a load signal line dependent upon a load signal. The load signal being generated via a load signal fluid having a fluid flow. Also disclosed herein is a hydraulic steering arrangement for carrying out the method. A load signal adjustment device is provided through which the fluid flow can be adjusted to an at least approximately constant value.

Abstract: Apparatus for controlling the movement of hydraulically movable work equipment that is arranged at the end of a length-adjustable and pivotable arm, along a substantially rectilinear path of movement, the work equipment being moved with the assistance of hydraulic drive units that act on the arm in dependence on input control signals that determine the path of movement. Even in the case of non-ideal control loops for the control of the drive units, it is intended that the work equipment be moved along a desired path. For that purpose, starting from an actual position of the work equipment, a sequence of desired positions in the path of movement is ascertained and the work equipment is moved from an actual position to the next desired position, the movement into the next position not being initiated until the work equipment is located in a predetermined tolerance band about the preceding position.
