Abstract: The invention relates to a composition comprising a thermoplastic polyurethane, where the thermoplastic polyurethane has been prepared from a) a diisocyanate, b) a polyol comprising a polyol A and a polyol B and c) a chain extender, optionally with the aid of catalysts and optionally further comprising additives and/or auxiliaries, and a salt and/or an ionic liquid, preferably an ionic liquid, is comprised in the composition and the polyol A comprises ethoxy and propoxy groups and the polyol B comprises butoxy groups.

Abstract: A pipe switch having a setting system, a housing and a closure element. The housing includes an inner wall in which a feed opening and at least two discharge openings are provided. The position of the closure element is rotatably changeable relative to the discharge openings. The setting system including a control and a drive controls the closure element such that a plurality of positions of the closure element relative to the discharge openings are realized accordingly. The closure element may be in the form of a slide or a two-part element having flaps. The setting system in cooperation with the closure system provides the plurality of positions of the closure element relative to the discharge openings, in each of which the sum of the cross-sectional areas of a first and of a second discharge opening not covered by the closure element is substantially constant.

Abstract: The present invention relates to a process for the continuous production of thermoplastically processable polyurethane elastomers, by metering a polyisocyanate (A), a proportion of 1-80 equivalent%, based on the isocyanate group content of the polyisocyanate (A), of a compound (B) having an average of at 1.8-3.0 hydrogen atoms having Zerewitinoff activity, with an average molar mass of 450-5000 g/mol, and a proportion of 12-99 equivalent%, based on the isocyanate group content of the polyisocyanate (A), of a chain extender (C), into a self-cleaning twin-screw extruder whose diameter is 32-62 mm, which is operated at shear rates above 6000 s?1 and residence times of 1-20 seconds, and then bringing the mixture from the self-cleaning twin-screw extruder into a second apparatus in order to complete the reaction.

Abstract: A method for extracting bulk material from a container which is open at the top by means of a suction apparatus which comprises at least one suction pipe (10) and one or more scrapers (12), with the suction apparatus being laid from above onto the surface of the bulk material in the container and bulk material being sucked away through the at least one suction pipe (10), wherein, during a repeated relative rotational movement between the scraper (12) and the surface of the bulk material in the container, bulk material is conveyed along the one or more scrapers (12) in the direction of the at least one suction pipe (10).
