  • Patent number: 11471966
    Abstract: The invention relates to a work station for electrochemically machining a workpiece, having a number of recesses, including a base structure; a module which is fastened to the base structure and is configured to electrochemically machine the workpiece. A workpiece holder is fastened to the base structure. The workpiece holder is movable relative to the base structure along a feed axis which is parallel to the axis of rotation of the module. The module includes an electrode carrier arrangement, which is coupled to the module base body so the electrode carrier arrangement can be rotated together with the module base body about the axis of rotation of the module. The electrode carrier arrangement has a carrier frame and an electrode frame, where at least one electrode is detachably fastened to the electrode frame.

  • Patent number: 10201845
    Abstract: The invention relates to a device and a corresponding method for manufacturing brush seals with obliquely positioned bristles. The method comprises the following steps: As the first step, a metal filament or wire (50) comprising a material for bristles is wound over two wire cores (42, 46) disposed at a distance from and running parallel to one another, to form a tightly packed metal filament or wire package (48). As the next step, the metal filament or wire package (48) is fastened to at least one wire core (42, 46). Then the region around at least one of the two wire cores (42, 46) is locally heated. Subsequently, at least one of the two wire cores (42, 46) is displaced.

  • Patent number: 7270843
    Abstract: A device and a method used when coating a wafer is described. The fluid coating is provided by an inside coating as well as an edge coating. The fluid chocolate in a container is stirred by displacing a vat up and down. During this displacement, the vat will be brought in contact with the wafer, so the chocolate substance, which is provided in there, provides an edge coating. Displacement of the first vat provides a repression of the chocolate substance, which through a nozzle is injected into the wafer in order to provide an inside coating. By repression, a pumping occurs, which is interrupted substantially simultaneously with the edge of the wafer getting in contact with the surface of the chocolate in vat, when it is elevated up towards the wafer, which is suspended in a commonly known apron conveyor (not shown).

  • Patent number: 7005151
    Abstract: There is described an apparatus (1) that may be used for providing ice lollies (2) with a coating from a dipping container (4). The coating mix (3) comprises almond flakes (16) and fluid chocolate (10) which is inserted in a third area (38). Displacement bodies (25) are lifted and lowered into first areas (28) while the ice lolly (2) is lowered in a central second area (20). The lowering occurs when the displacement means are completely down whereby a well-defined surface level (23) is achieved by using level plates (21). The movement of the displacement means (25) creates sufficient stirring and flow in flow ducts (36, 43) in order to ensure homogenisation of the coating mix (3) situated in the central second area (20) where the ice lollies (2) are coated.
