  • Publication number: 20190237224
    Abstract: The invention describes electrically conductive shaped bodies with an inherent positive temperature coefficient (PTC), produced from a composition which contains at lest one organic matrix polymer (compound component A), at least one submicroscale or nanoscale, electrically conductive additive (compound component B) and at least one phase-change material with a phase-transition temperature in the range from ?42° C. to +150° C. (compound component D). The phase-change material is incorporated into an organic network (compound component C). The electrically conductive shaped body with an inherent PTC effect is, in particular, a filament, a fibre, a spun-bonded web, a foam, a film, a foil or an injection-moulded article. The switching point for the PTC behavior is dependent on the type and also the phase-conversion temperature of the phase-change material. By way of example, a self-regulating surface heater in the form of a film, foil and/or textile can be realized in this way.

  • Patent number: 6305834
    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.

  • Patent number: 6299657
    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.

  • Patent number: 6225497
    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.

  • Patent number: 6082891
    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.
