Abstract: A dosing device for outputting bulk goods from a dosing container is described. An exemplary embodiment includes at least one discharge arm, arranged above the bottom of the dosing container so as to be driven about an axis of rotation. The arm supplies bulk goods in the lower section of the dosing container to at least one output opening. The wall in the lower section of the dosing container extends from a cylindrical section above in a truncated cone-shaped manner and encompasses at least a part of the output opening. The output opening extends to the bottom of the dosing container. The at least one discharge arm includes a blade having a distal edge located opposite the axis of rotation, the edge is shaped to correspond to the cone-shaped wall of the dosing container, and a peripheral speed at the edge is below 1 m/s during normal operation.

Abstract: The invention relates to a weighing scale comprising a base plate and a load plate on which the object to be weighed is placed or on which the person to be weighed stands. At least three planar load cells are arranged between load plate and base plate which load cells are fastened to the load plate and are loosely supported on elevations of the base plate.

Abstract: A process for controlling the throughput rate of aeration air when composting organic waste and/or sewage sludge migrating through a closed reaction vessel from an inlet opening to an outlet opening while aeration air supplied to the reaction vessel flows countercurrently through it, wherein a measured value corresponding to the O.sub.2 content of the waste air evacuated from the reaction vessel is continuously produced and, starting from a minimum value, the throughput rate of the aeration air is increased up to a maximum value until the measured O.sub.2 content of the waste air has dropped to its minimum value, and is decreased again when the O.sub.2 content of the waste air increases, the minimum value of the throughput rate being the value at which the O.sub.2 content of the evacuated waste air just begins to drop as compared to the O.sub.

Abstract: Motive power device for a delivery device located at the base of an upright silo in the shape of a worm screw rotatable about its longitudinal axis, which is swivelable around a central bearing across a circular annularly shaped bottom surface of the silo with the help of a step motor, which consists of two identically designed shoe brakes self-locking counter to the drive direction and engaging at an abutment assigned to the silo wall, of which the one is linked rigidly and the other one displaceably through a controllable power cylinder in the area of a support bearing of the worm and cooperates with the abutment located at the silo wall.
