Abstract: A plastic is manufactured on the basis of at least four starting components (A, B, C, F) of which at least a first primary component (A) and a second primary component (B) can react with one another. A chemical reaction of the two primary components (A, B) is accelerated in such case by addition of at least one secondary component (C) serving as a catalyst. Additionally, according to the method, a tertiary component (F) serves as a filler, especially a color-giving filler. Initially a first multicomponent system (BF; CF; BCF), especially also a storable system, serving as an intermediate component, is formed, which contains, at least in part, both the secondary component (C) as well as also the tertiary component (F). Additionally, on the basis of the first multicomponent system (BF; CF; BCF) a flowable, especially liquid, second multicomponent system (ABCF) is formed, which contains the four starting components (A, B, C, F) in concentrations enabling the chemical reaction of the primary components (A, B).

Abstract: An apparatus for measuring volume- or mass-flow of a medium in a pipeline. The apparatus includes: a measuring tube, through which medium flows in the direction of the measuring tube axis, wherein the measuring tube has, in stream direction of the medium, a first end region and a second end region; a magnet system, which a produces a magnetic field passing through the measuring tube essentially transversely to the measuring tube axis; at least one measuring electrode coupled with the medium and arranged in a region of the measuring tube lying essentially perpendicular to the magnetic field; and a control/evaluation unit, which delivers information concerning volume- or mass-flow of the medium in the measuring tube on the basis of a measurement voltage induced in the at least one measuring electrode. In order to keep costs for the magneto-inductive flow measuring device low, the measuring tube is embodied as one-piece and the first end region and the second end region of the measuring tube are flared.

Abstract: A method for the manufacture of a measuring tube of a flow measuring device, and to a flow measuring device. The measuring tube has a lumen for accommodating a flowing, measured material. The method comprises: introducing at least one, essentially cylindrical, hollow body into a support tube; joining the essentially cylindrical, hollow body to the support tube by mechanically deforming at least one portion of the essentially cylindrical, hollow body; and embedding the hollow body joined to the support tube in an electrically and/or chemically insulating, isolating material; wherein the lumen of the measuring tube is formed by the electrically and/or chemically insulating, isolating material.
