Abstract: A conveyor apparatus for a particulate material to be conveyed, e.g., a synthetic resin granulate or powder, with a plurality of handling devices (30, 31) for processing the conveyed material, a storage bin (20) for the material to be conveyed, a conveying line (2) provided with a suction probe (1) for withdrawing the material to be conveyed from the storage bin, and a negative pressure source (4) connected to the handling devices via a suction line (7). The handling devices (30, 31) are all connected to a common conveying line (2), and a control member (8) is provided on the suction probe (1) to control the air volume going through the conveying line (2). This control member is controlled by an air pressure sensor (5) disposed on the suction line (7).

Abstract: An apparatus for conveying granular plastic materials, for example silicone granulate, including a storage tank, a device for loosening granular plastic material positioned within the storage tank, as well as a discharge device for indirectly or directly transporting granular material to an extruder antechamber. Even granular plastic materials that are difficult to pour can be conveyed in a reliable and economical way due to the process of loosening the granular plastic materials by means of a suitable device.

Abstract: An apparatus for supplying scraper pigs, e.g., to material supply pipelines, which has within a housing at least one feeder or supply magazine which has at least two chambers, each chamber being able to hold one pig. The apparatus also has at least one drive which serves to drive the at least one feeder, and at least one pig inlet and at least one pig outlet.

Abstract: The invention relates to a process and an apparatus for closing and/or opening a hopper or container (5) with a bottom outlet. A flap (7) fastened to at least one lever mechanism (2) is urged toward a closed position by means of a counterweight (6) mounted on the opposite end of the lever mechanism (2). At least one driving element (9) operatively connected to the shaft (8) supporting the lever mechanism (2), via a partial free wheel mechanism composed of a pair of conditional forcible drive members (3, 4) mounted on the shaft, promotes the closing of the flap (7) when the force of gravity acting on the counterweight does not bring the flap to the fully closed position.

Abstract: A multi-way distributor having at least two mutually parallel and displaceable disks provided with at least two through-holes or connection pieces. At least two flexible tubes are fastened to at least two of these displaceable disks, and by the relative movements of the disks with respect to one another, different connections can be achieved which the distribution of the material flows takes place.
