Abstract: Method for the in situ formulation of a medicinal substance solution for parenteral administration, in which at least two metered part-streams are continuously combined with the aid of a mixer to an active ingredient-containing total volumetric flow, characterized in that the resulting medicinal substance solution is not in thermodynamic equilibrium, and in that the resulting total volumetric flow after mixing is 0.2 ml/h to 500 ml/h, preferably 5 ml/h to 500 ml/h, an apparatus for carrying out the method, and an active ingredient administration kit which contains the apparatus.

Abstract: In the process for the continuous dispersion of at least one fluid A constituting the disperse phase and at least one continuous phase constituting the enclosing phase of a fluid B, at least one fluid stream A and at least one fluid stream B are fed into a dispersion apparatus and come into contact therein in a dispersion chamber.

Abstract: A method and a device for producing a dispersed mixture from at least two phases. To do this, the first and the second phase are subdivided into split streams so that the split streams from the first phase are located on a first flat layer and the split streams from the second phase are located on a second flat layer, the split streams of the first phase inside the flat layer being fed onto the split streams of the second phase at an angle in order to bring about a dispersion and mixing process, wherein the flat layers are directly arranged on top of each other, and parallel to each other. The device consists of at least one base unit containing two foils into which a parallel assembly of grooves is inserted on one side of each foil. Both foils are configured in the base unit such that the sides of the foils fitted with grooves lie on top of each other and form an angle with each other.

Abstract: In the reaction process, at least two educts A, B are divided by a system, assigned to each of them, of slit-like microchannels 1a, 1b into spatially separate fluid lamellae, which then emerge into a common mixing and reaction space 4. The fluid lamellae here have a thickness <1,000 &mgr;m, preferably <100 &mgr;m, at a width thickness ratio of at least 10. It is essential here that educts A, B can emerge as thin fluid lamellae 6a, 6b into the mixing/reaction space 4, each fluid lamella 6a of an educt A being led into the mixing/reaction space 4 in the immediate vicinity of a fluid lamella 6b of another educt B. The adjacent fluid lamellae 6a, 6b then subsequently mix by diffusion and/or turbulence. As a result, the mixing operation is accelerated substantially compared with conventional reactors. In the case of rapid chemical reactions, the formation of undesirable by-products or secondary products is largely prevented in this manner.

Abstract: A microstructures lamellae mixer comprising a guide component for supplying fluids to be mixed to a mixing chamber, the guide component being composed of a plurality of foils which are layered one above the other and into which microchannels are incorporated such that separate fluids supplied to the guide component are formed into spatially separated microstreams which then emerge adjacent to each other in a mixing chamber.

Abstract: A process for rapidly mixing phosgene and an amine in the gas phase to produce the corresponding isocyanate. Micro-structure mixers are used for the rapid mixing. The educts emerge from the micro-structure mixer in the form of thin free jets which mix very rapidly by diffusion and/or turbulence. As a result, the mixing operation is accelerated substantially as compared with conventional reactors. The isocyanate yield is also increased.

Abstract: In a static micromixer a flow guide structure consisting of a stack of foils provided with passages formed into alternate foils so as to extend between a mixing chamber at one end of the flow guide structure and different admission chambers at the opposite end of the flow guide structure, the passages are curved so that they are all parallel at their exit ends adjacent the mixing chamber and, at their entrance ends, the flow guide structure has face areas which are inclined with respect to the exit end face of the flow guide structure at such an angle that the curved passages have all about the same length.

Abstract: At least one absorbent is added to the exhaust gas, which is passed at temperatures in the range from about 40.degree. to 500.degree. through a fluidized bed reactor and through dedusting means. Part of the solids separated in the dedusting means is recycled to the fluidized bed reactor. At least part of the recycled solids is blown with an entraining gas upwardly through a tube into the lower portion of the reactor. At least part of the combustion exhaust gas is fed to the reactor as a rising stream from a space which surrounds the tube. Air or combustion exhaust gas may be used, e.g., as an entraining gas.

Abstract: The process of removing dust, sulfur compounds and nitrogen oxides from combustion exhaust gases, comprising mixing a combustion exhaust gas with ammonia; feeding Ca(OH).sub.2 and FeSO.sub.4 to a fluidized bed reactor containing mixed solids including fly ash, iron sulfates and calcium compounds, especially Ca(OH).sub.2, CaCO.sub.3, CaO, CaSO.sub.4 and CaSO.sub.3 ; supplying an ammonia-containing exhaust gas mixture to the fluidized bed reactor as a fluidizing gas; operating the fluidized bed reactor at a temperature between 300.degree. and 450.degree. C. to form a reacted exhaust gas; supplying the reacted exhaust gas to a multistage electrostatic precipitator having a first stage and additional stages; recycling solids collected in the first stage to the fluidized bed reactor; and recycling one portion of additional solids collected in the additional stages to the fluidized bed reactor and discharging another portion of the additional solids.

Abstract: There is disclosed a method of manufacturing and marking a cable including the steps of drawing a plurality of conductors in a longitudinal direction through an apparatus that affixes a plurality of magnetizable inserts along the length of the conductors with a distribution associated with a plurality of particular locations along the length of such conductors; applying a protective jacket of insulating material about the conductors and affixed magnetizable inserts; and marking the outside of the protective jacket in accordance with control signals generated by a sensing device that detects the presence of each of the magnetizable inserts as the cable is drawn through the sensing device.
