Abstract: A tail station for a scraper chain conveyor, in particular a transfer conveyor, including a machine frame having bearing holders, which are open at the margins, for a demountable chain wheel assembly, including a chain wheel assembly having a chain wheel shaft, a reversing chain wheel and bearing shells for the rotatable mounting of the chain wheel shaft, and having a deflector element assigned to the reversing chain wheel, the bearing holders being configured on cantilever arms connected to the machine frame and are upwardly open, wherein the chain wheel assembly is provided on the bearing shells with bearing blocks, which can be inserted with horizontal motional play into the bearing holders and are horizontally displaceable in the bearing holders between a removal position and a locking position.

Abstract: The invention relates to a DLP-projector for the active projection of stereoscopic images, with the projector comprising a DMD, at least a first driver circuit interacting with a memory (6) and controlling at least one DMD (4), and at least a first signal input (1) for the input of image data of at least a first image channel and a second image channel. In order to enable simplest possible construction of such a DLP-projector, there are provided: A second driver circuit interacting with a memory (6?); and a switching device (7), which is connected on one side with the two driver circuits and on the other side with at least the one DMD (4); with the first driver circuit processing image data of the first image channel and the second driver circuit processing image data of the second image channel; and the switching device directing to the DMD (4) alternately one or more images or frames from the first driver circuit and one or more images or frames from the second driver circuit.

Abstract: In order to develop a lighting apparatus having a light source unit which has at least one light source and a first reflector, and having at least one optical element, with the light which is emitted from the light source being focused by the first reflector to form a light beam which can be influenced by the optical element further, in such a manner that the type of structure, in particular the diameter of the light outlet openings of the lamp housing, does not restrict the optical elements which can be used, said apparatus has a reflector unit having a second reflector and having a concave third reflector, with the concave third reflector having an opening for the light beam and the light beam being reflected by the second reflector onto the third reflector, and with the optical element being arranged between the light source unit and the reflector unit.

Abstract: Effect wheel rotation system, having a base and at least one effect wheel which is coupled thereto and can be rotated about an axis of rotation by means of a drive, the axis of rotation being arranged offset with respect to an optical axis and the effect wheel having at least one optical element which can be rotated into the region of the optical axis, in which system the effect wheel, independently of a rotation about the axis of rotation, can also be rotated about the optical axis.
