Abstract: A bolted attachment having opposite threaded sections between which a shank is provided having at least two shank sections with different diameter located at a length from the threaded section of at least three times the difference between a diameter of a threaded section and a minimum diameter of the shank. At least one conical transition is formed between two adjacent shank sections where the ratio of its length to a difference between a diameter at one end of the transition and a diameter at the opposite end of the transition is of at least 0.85.

Abstract: A two-piece socket for a ball-and-socket arrangement, including a base and a cap. The socket includes a leg on one of the cap or base of the socket and a receiving groove on the other of the cap or base of the socket, wherein there is at least one opening in the leg which lines up with a corresponding opening in the groove for a fastener to extend through these openings to releasably secure the cap to the base of the socket. The orientation of the fastener is such that the fastener is under shear loading when the cap is pulled apart from the base.

Abstract: An electrical machine comprising a first item having a male portion and a second item having a female portion. The male and female portions have a shape adapted to each other such that the male portion can be fitted into the female portion. The male and/or female portion is formed as a stack of sheets comprising standard sheets and protruding sheets. The “male” standard sheets substantially fit into the female portion and the “male” protruding sheets are larger than the female portion such that, in use, said protruding sheets are deformed during insertion of the male portion into the female portion. The “female” standard sheets have an opening into which the male portion substantially fits, and the “female” protruding sheets have an opening smaller than the male portion such that, in use, said protruding sheets are deformed during insertion of the male portion into the opening of the female portion.

Abstract: The invention relates to a non-toxic composition prepared from agricultural waste, including steps of a) hydrolysing the plant matter in acidic conditions; b) nitrating the released phenolic compounds; c) stimulating the coupling between the phenolic compounds which are nitrated or not; d) insolubilizing and separating the coupled compounds; and e) drying the precipitated insoluble solids. The resulting composition, when applied to plants, has phytoregulating properties that induces favorable metabolic and physiological changes which promote increases in the mass of the roots and the photosynthetic capacity, in the resistance to biotic factors, in the tolerance to abiotic stress factors and/or in the productivity of the crops.

Abstract: It includes at least one platform defining a plane, first and second sets of complementary coupling elements associated with the tower section and the platform respectively, and arranged in levels. In a first relative position of the sets of coupling elements, the platform is allowed to pass, in a substantially horizontal position, through different levels of sets of coupling elements and in a second relative position of the sets of coupling elements, the platform rests with its second set of coupling elements on a first set of coupling elements of one given level. A device for moving the platform may be provided for fitting it inside the tower section. The first or the second set of coupling elements in different levels are aligned along a longitudinal direction inside the tower section.

Abstract: It includes a rotatable hub carrying blades and a device for attaching a portion of the blades to a portion of the hub. The attaching device includes bushings inside of which corresponding studs can be secured. At least some of the bushings are provided with at least one securing end adapted for providing the stud with a degree of rotation relative to the bushing. Bushings may include an inner receiving member for receiving a corresponding end of the stud. The receiving member can be rotated inside the bushing around an axis.

Abstract: A wind turbine lubrication system comprising a pump for pumping lubricant through a lubrication circuit, said pump being driven by a power-take-off from the drive train of the wind turbine, characterized in that said pump for pumping lubricant drives at least a first hydraulic motor providing mechanical power to a first wind turbine auxiliary component.

Abstract: A wind turbine is described. The turbine includes a hub with one or more blades. The hub is rotatably mounted on a frame and operatively coupled to a shaft through a coupling plate mounted on the shaft. The shaft is provided at least partially internally to the frame, and the shaft is a substantially tubular hollow shaft.
