Abstract: An automatically or manually operable closure system for a closing flap on a transport container is situated on the container frame and a docking stand at an unloading station. A rotating device for moving the closing flap is provided on the docking stand and a locking device for locking the closing flap in the closed position is provided on the container frame. A flap shaft, whose other end is mounted rotatably in the container frame and is implemented as a first connection element, engages axially to the rotational axis of the closing flap. The first connection element is axially coupled using a torsion-fixed tongue-groove pair to an axially displaceable second connection element. Formfitting coupling elements are provided on the second connection element and on the driveshaft for moving the closing flap.

Abstract: The invention relates to a method and a device for monitoring the optical transmissibility of an observation window (2) for the spectroscopic analysis of the homogeneity of a mixture material in a mixing container. According to the method, a product-specific limit value for the spectroscopic data is stored in the analysis unit, which limit value must be undershot within a prespecified time. If the data does not fall below the limit value within that time, the analysis unit emits a signal which contains information to the effect that the observation window (3) is soiled to an unacceptable degree. The device comprises an analysis unit in which product-specific limit value for the spectroscopic data can be stored, a cleaning device for cleaning the observation window and a switching unit for activating the cleaning device. The analysis unit is suitable for emitting a signal if the limit value is not undershot during the mixing process within a prespecified time.
