  • Publication number: 20060236573
    Abstract: The invention relates to a display apparatus for changing images. The apparatus comprises a cassette unit adapted for replacement as a single unit. The cassette unit comprises multiple sheet-formed image carriers (21,22,23,24). The image carriers (21,22,23,24) comprises image parts constituting at least two different images. The image carriers (21,22,23,24) are subdivided into panels adapted for sliding between each other. The cassette unit further comprises a back plate (42) covering a side of one of the image carriers (21,22,23,24). The display apparatus further comprises moving means (30) for moving the different image carriers (21,22,23,24) relative to each other, and a frame (28) for supporting the cassette with the image carriers (21,22,23,24) and the moving means. According to the invention, one of the image carriers (21,22) is fixedly attached to the back plate (42) along its edges.

  • Patent number: 6699121
    Abstract: An agricultural harvesting machine has a comminuting device which includes a chopper rotor having a rotor shaft, and a conveying element pivotably connected with the rotor shaft. The conveying element is formed by a first arm and a second arm which are interconnected by a cross web. In one embodiment the cross web has a recess between the first and second arms, and a cutting element is provided which passes either through the recess of the conveying element or outside of the first and second arms of conveying element as the conveying element rotates. In another embodiment the conveying element is provided with both leading and trailing cutting edges arranged in sets. Initially one set of cutting edges is utilized and the conveying element can latter be reversed in position to utilize the other set.

  • Patent number: 5184822
    Abstract: The invention provides a three-dimensional puzzle which consists of a box-like casing and a number of flat plate-like game pieces that are freely movable relative to each other within a closed system defined by the casing. The game pieces are, distinguishable from each other by markings such as symbols or color.The casing is a substantially closed, shape-rententive hollow body of the shape of a geometric solid bound by lateral faces. At least four such lateral faces are identical to each other in size and shape. The interior of the casing serves as a game space for the enclosed game pieces. The game pieces are of a shape that is substantially identical to that of the at least four lateral faces of the casing and are laid out in size so that they are permitted free movement within the game space.
