Abstract: A device for removing flat materials from a mixture of valuable substances comprises a conveyor (1) on which the substance mixture is conveyed, and an extractor for extracting flat materials from the substance mixture in an extraction zone. The extractor comprises extracting prongs (4) which are provided on a revolving transporter (3) which is deflected at least at two points of deflection, with the materials which have been picked up being discharged in a discharge zone.

Abstract: An apparatus for charging a trash sorting device with the contents of trash bags has a feed apparatus of the trash bags connected to an inclined conveyor belt suitable for bearing and transporting trash bags, the upper end of which is located above the charging point of a conveyor which traverses the sorting area. Located above and near the upper end of the conveyor belt is a deflector rake which can be swiveled around an axle which traverses the conveyor belt, the tines of which rake when in the pick up position approach the conveyor belt at a downward angle in the direction opposite the direction of transport of the belt and can be moved from this pick up position opposite the direction of transport to a reject position above the conveyor belt. The deflector rake can be driven in a back-and-forth motion between the pick up position and the reject position.

Abstract: A pivotal implement, such as a pivotal plow includes an implement frame having an axle extending longitudinally in the direction of travel which is pivotally supported on an undercarriage for movement relative thereto about its axle. The undercarriage includes a pair of spaced apart wheels each of which is supported by a transversely-extending axle which is coupled to the undercarriage for independent vertical movement in a substantially vertical direction, relative to the longitudinal axis of the undercarriage, for movement between an upper limiting position and a lower limiting position. Blocking means are associated with each of the wheel axles for preventing a tipping of the undercarriage relative to the implement frame about its longitudinal axis.
