Abstract: Methods and computer systems are provided for data assignment. A computing unit and a data object component for managing a set of data objects are provided. Data objects of the set of data objects can be divided into segments according to selectable criteria. An interface unit may also be provided to interconnect the computing unit and the data object component. The interface unit may be arranged and constructed to include an inventory assignment of segments created in the data object component such that, in case of an assignment inquiry by the computing unit, an assignment of one or more segments being inquired for is carried out in the interface unit.

Abstract: The invention relates to a roller mill with two rollers driven in opposite directions, in which the two gear driven cases are connected directly to one another by a torque support containing a flexible member.

Abstract: The invention relates to a percussion jig in which the chutes for receiving and discharging the material to be separated are each divided into a plurality of individual chute segments arranged spaced from one another so that the spaces between adjacent individual chute segments facilitate a free equalization of the levels of the settling fluid during the upward and downward movements of the settling tank.

Abstract: The invention relates to a percussion jig in which the carrier for material to be separated is freely suspended in the region of its centroidal axis on the piston rod of a hydraulic drive cylinder. This results in a particularly simple construction subject to little wear.

Abstract: An arrangement for controlling the advancing device of a machine for repetitive operations, especially for controlling the advancing speed of a slide carrying a cutting device of a cutting machine for cutting an elongated workpiece, such as a profile emanating at a predetermined speed from an extrusion press, a straightening machine or the like, into sections of uniform length.
