    摘要： A sensor device having an incremental encoder and a measuring sensor generating a measuring signal is assigned to two control devices. A synchronization device generates a synchronization signal. A conditioned first measuring signal is generated in the first control device as a function of the measuring signal. A conditioned second measuring signal is generated in the second control device as a function of the measuring signal. The value of the conditioned first measuring signal at a predefined time after the reception of the synchronization signal in the first control device is transmitted to the second control device. The second control device synchronizes the conditioned second measuring signal as a function of the values of the conditioned first and second measuring signals that the signals have at the predefined time after the respective reception of the synchronization signal in the first and second control devices.

    摘要： An apparatus for delivering powder onto a plane surface (1) of a device for creating a three-dimensional part in a layer-by-layer fashion, in particular of a laser sintering machine, is provided. It comprises a covering means (3) which can be moved back and forth in a second direction perpendicular to said first direction by means of a drive between a lateral first position and a second position located on the opposite side. In at least one of the positions it can be filled with powder. In order to simplify the apparatus and improve its operation, the covering means (3) comprises a slit (6) extending across the entire width and open at its top and its bottom as well as smoothening elements (7, 8) at the ends opposite of the surface. A store container (9) is provided above the covering means (3), the volume of said store container at each location across the entire width being at least equal to the volume of the slit cavity located underneath.
