Abstract: A micromechanical structure, in particular an acceleration sensor, is described, having a substrate, a seismic mass, which is movable relative to the substrate, and at least one anchoring element, which is fixedly connected to the substrate, the seismic mass being attached to the substrate by the anchoring element, and at least one spring element being situated between the seismic mass and the anchoring element, and furthermore, the anchoring element has at least one stop element for interaction with at least one counterstop element of the seismic mass.

Abstract: A screen assembly for grain husking, decorticating, polishing and whitening machines, the assembly to be mounted on a frame part of the respective machine. The assembly comprises at least two screen sectors which form a substantially cylindrical shape around a longitudinal axis in assembled condition. A frame is provided for each of the screen sectors for framing and supporting the screen sectors by reinforcing the circumference of the screen sectors. An axle arrangement on at least one of the frames extends substantially parallel to the longitudinal axis and is provided for adjusting the distance between the longitudinal axis and a respective one of the screen sectors and one circumferential side of the screen sectors. The axle arrangement comprises a first and second axle parallel to each other within the range of two adjacent circumferential sides of two adjacent screen sectors. A pitman rod connects the axles.

Abstract: A rotor disc for accelerating and projecting particles radially outwards off the disc toward an encircling impact element includes a rotatable disc base having radial channels for guiding particles radially outwards. The channels are formed of side walls fixed to the disc base with side faces on opposite sides of each channel. The corresponding side faces of each pair of sidewalls are arranged essentially parallel and have, in each pair of opposed faces, at least a first face which a radial chamfer having at least a first and a second chamfer face which are angled to form a groove disposed above the disc base for guiding the particles.

Abstract: Impact mill comprising a housing (1) wherein a drivable centrifugal rotor (3) rotatable about a rotational axis (8) and an impact body (7) enclosing this centrifugal rotor are provided. At least one sensor (11, 111, 211, 311, 411) is assigned to the impact ring (7), which sensor functions during the operation of the mill and which is designed for detecting at least the operational efficiency, preferably also for determining the extent of the wear of the impact ring (7). The sensor (11) senses the impact body (7) through an opening (12) in its annular or cylindrically-shaped housing (13).

Abstract: A distribution head of an impact mill rotates about a vertical axis and throws raw material against a cylindrically-shaped impact body. The latter has a rotational axis, which forms an angle with the vertical axis to equalize the wear over the height of the impact body.
