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: 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: 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.

Abstract: A beverage mixer and dispenser is disclosed. The housing of the beverage mixer and dispenser includes a mixing chamber and an extract container positioned above the mixing chamber. A metering device is positioned between the extract container and the mixing chamber to allow dispensing of a desired amount of extract from the extract container into the mixing chamber. The beverage mixer and dispenser includes a feed opening, which is exposed at an exterior surface of the housing and leads into the mixing chamber to allow for manual addition of drink additives to the mixing chamber. The beverage mixer and dispenser also includes a cream chamber. The cream chamber is adapted to receive a liquid-extract combination from the mixing chamber. A rotatable mixing rotor is positioned within the mixing chamber and a rotatable first cream rotor is located within the cream chamber to provide thorough mixing of the liquid-extract-cream combination.

Abstract: Appliances for the preparation of hot drinks are described herein. The appliances include a water container having a container outlet from which, via a heating device and a riser, water heated by the heating device can be supplied to a mixing device. A specific water level height in the riser can be kept at least largely constant by a constant level holding device.

Abstract: The invention is directed to a device for chopping food, in particular ice cubes, which includes a container body (2) subdivided into an upper processing zone (20) and a lower collecting zone (21). The rotary chopping tool (3) received in the processing zone (20) serves to comminute the food materials. A sieve (4; 25; 26) is provided in the transition region from the processing zone (20) to the collecting zone (21). The device of the invention has the advantage of enabling both foodstuffs and ice cubes to be reduced to defined sizes readily. In addition, ice cubes may be reduced without major amounts of energy being absorbed by the chopping tool (3) and without the reduced parts beginning to melt.

Abstract: A processing container for foodstuffs, with a removable container lid and a tool shaft arranged in the container interior and having processing tools fitted thereto, with the tool shaft being mounted for rotation about its center axis in a vertical position by means of an upper bearing arrangement in the container lid and a lower bearing arrangement in the container bottom. The lower bearing arrangement is configured such that the tool shaft is rotatably and tiltably mounted thereon, thereby enabling the tool shaft to be locked in a tilted position when the container lid is removed.

Abstract: The invention relates to a working container (1) which is used to receive and process foodstuffs. The working container (1) is provided with a bottom (3) on which a bearing journal (11) can be placed for rotationally mounting a working tool (34) which processes the foodstuffs. According to the invention, a recess (20) is embodied in the bottom (3) of the container. The bearing journal (11) extends into said recess, whereby food which is not to be comminuted in the receiving area (32) by the usual working tool (34) can be processed, for example, by a working tool (56) of a rod mixer (57) or another working tool of a hand mixer, said working tools (56) not being able to come into contact with the bearing journal (11).
