    摘要： A device for determining the rotational speed and position of a rotor of an electric motor having at least one signal track arranged on the rotor includes at least one sensor located at a stator-side of the electric motor for scanning the signal track, and an evaluation circuit connected to the sensor, the sensor being sensitive to given stimuli of the signal track for alternatively adopting one of three different states which individually produce levels of different magnitude; the evaluation circuit including detectors responsive in accordance with the levels, for cutting off levels of given magnitude so that a recognition of the rotor position is derivable from a first and a second one of the three states, and the rotational speed is derivable from the third one of the three states.

    摘要： A device for producing multi-layer composites made of thermoplastic materials, including a coextrusion adapter through which the thermoplastic materials can flow. The adapter has an inlet opening and an outlet opening, in which the thermoplastic materials are combined in layers. The coextrusion adapter has a modular design including a plurality of housings stacked on top of each other in a modular manner, each having a central channel arranged in the housing and at least one coextrusion channel opening into the respective central channel. The central channels of the housings stacked on top of each other continue one another, and the thermoplastic materials can flow through the central channel and the coextrusion channels in the direction of the outlet opening. Each housing further includes a receiving bore that extends through the central channel and into which a coextrusion pin can be inserted, which in turn has a channel bore that continues the central channel and in some regions forms a partial section of the at least one coextrusion channel between the outer surface and the wall of the receiving bore.

    摘要： A method and a device for producing a film made of a thermoplastic material, wherein a plastic melt is blown up into a film bubble and is shaped into a desired film by a calibrating arrangement, and a downstream arranged flattening device. For providing as contactless as possible a guidance, calibration and flattening, film guidance elements are used with a laminar uniform air cushion between the film guidance element and the surface of the film bubble, without contact between the surface of the film bubble and the film guidance element.
