Abstract: The invention relates to a device and method for separating bulk materials with the aid of a blow-out device provided with blow-out nozzles arranged on a fall section which is disposed downstream from a conveyor belt. The blow-out nozzles are controllable by computer-controlled evaluation means according to sensor results of radiation, which penetrates the flow of bulk material on the conveyor belt, and emitted from an x-ray source and captured in the sensor means. The x-ray radiation, which passes through the particles of the bulk material, is filtered into at least two spectra of differing energy ranges before the radiation is captured by local resolution with the aid of at least one sensor means integrated within an energy range.

Abstract: Method of coating a board and a board coating system for performing the method. The inventive method is intended for coating a board with liquid coating material, particularly for coating a basis plate intended for circuit boards with liquid photoresist. Here, the plate which is to be coated is transported by a transport apparatus past a coating roller while in contact with the latter. The coating roller is rotated in a vertical orientation and, during coating, the board is held by the transport apparatus on its upper edge in a vertically hanging position and is led past the vertically oriented coating roller by the transport apparatus.
