Abstract: A multi-region twin-shaft cutting system for chopping material. The cutting system includes two shafts which are arranged in parallel and are driven in an opposed manner, each shaft is surrounded by a roll body. The system additionally includes a multiplicity of supporting elements, each supporting element is fitted radially around the roll body. The system further includes a multiplicity of severing elements which are of disc- and/or plate-like design and are each fitted symmetrically or asymmetrically tangentially to the circumferential region of the supporting elements.

Abstract: A multi-region twin-shaft cutting system for chopping material, comprising: two shafts which are arranged substantially parallel and are driven in an opposed manner, wherein each shaft is in each case surrounded by a roll body; a multiplicity of supporting elements, wherein each supporting element is fitted substantially radially around the roll body, wherein each supporting element preferably has a shaft-shaped, symmetrical or asymmetrical circumferential line; a multiplicity of severing elements which are, in particular, of disc- and/or plate-like design and are each fitted symmetrically or asymmetrically substantially tangentially to the circumferential region of the supporting elements; wherein the supporting elements are arranged at a distance around the roll bodies in such a manner that in each case one severing element on one supporting element of the one shaft can engage between two directly adjacent supporting elements of the other shaft; wherein, for each shaft, mating severing elements are fitted i

Abstract: A rotary light switch for motor vehicles is presented that ensures a feel that is not susceptible to mechanical influences. The rotary light switch has an actuator that can be rotated around an axis and that can be moved in the axial direction, and that is non-rotatably coupled to a rotational position indicator and axially coupled to an axial position indicator. Moreover, it has an electronic evaluation circuit to which the signals from the rotational position indicator and from the axial position indicator are fed and, according to a permanently stored decision matrix, said evaluation circuit uses the signals to derive discrete switching states that are converted into switching signals that serve to actuate the lighting system of the vehicle. The rotational position indicator comprises a potentiometer that generates a negligible resistance to the rotational movement, so that no mechanical influences are caused by the rotational position indicator.

Abstract: In a method for robot-controlled cutting of workpieces to be joined by laser radiation, a first workpiece is arranged in vicinity of a second workpiece in a first position. A laser is focused onto the first workpiece. A contour of the first workpiece is cut with the laser beam; this contour is to be assembled and joined with the second workpiece. During cutting, a first spacing of a focal point of the laser beam from the second workpiece is repeatedly determined in a distance direction that is identically oriented during cutting and is adjusted to a direction of assembling the first and second workpieces. During cutting, a second spacing of a processing point of the laser beam from the second workpiece is maintained at a constant value.
