Abstract: An electrical tool includes a multi-stage gear transmission (10) located in the gear transmission housing (6) and having at least two axially displaceable indexing gear (42a, 42b), a shifting device (12) for shifting the gear transmission from one stage to another stage and having a shifting slide (14) linearly displaceable between different shifting positions, and at least two connection elements (32) for connecting the shifting slide (14) with respective indexing gears (42a, 42b), with the shifting slide (14) having a tracing profile (20) having two control tracks (22, 24), and the connection elements each having a first and second tracing sections (30a, 30b) to which the tracing profile (20) applies a shifting force in stages and which are arranged on opposite sides of a pivot axis (SA) of a respective connection element (32).

Abstract: A power tool includes an output member (8) projecting from the tool housing (4), a drive (6) located in the housing for rotating the output member (8), and a slip clutch (22) for transmitting torque from the drive (6) to the output member (8) and including a plurality of clutch elements (24) retained against rotation relative to the housing (4), a plurality of separate spring elements (28) for adjustable preloading the clutch elements (24) against the counter-clutch elements (51) of the control element (18) for retaining the control element (18) against rotation upon application of the torque thereto until threshold of the torque is reached, and a common support element for supporting the spring elements and movable relative to the housing (4).

Abstract: The invention relates to a method and a device for husking and degerminating grains of maize. The aim of the invention is to provide an efficient and simple degermination of maize. To this end, during a wet degermination process, cleaned maize is wetted, and then husked and degerminated, and directly supplied to the comminution stage.

Abstract: The invention relates to a method and installation for cleaning cereal grains, particularly wheat. Cleaned and moistened wheat is moistened once again on the surface thereof, and the outer hulls are removed in a hulling machine (20). Afterwards, the dehulled cereal grains can be ground and polished.
