Patent number: 6321998Abstract: 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.Type: GrantFiled: May 5, 1998Date of Patent: November 27, 2001Assignee: Bayer AktiengesellschaftInventors: Klaus Schubert, Wilhelm Bier, Gerd Linder, Erhard Herrmann, Bernd Koglin, Thomas Menzel

Patent number: 6305834Abstract: 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.Type: GrantFiled: August 2, 1999Date of Patent: October 23, 2001Assignees: Forschungszentrum Karlsruhe GmbH, Bayer AGInventors: Klaus Schubert, Wilhelm Bier, Gerd Linder, Erhard Herrmann, Bernd Klinksiek, Bernd Krumbach

Patent number: 6299657Abstract: 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.Type: GrantFiled: October 15, 1999Date of Patent: October 9, 2001Assignee: Bayer AktiengesellschaftInventors: Klaus Schubert, Wilhelm Bier, Gerd Linder, Erhard Herrmann, Bernd Koglin, Thomas Menzel, Christine Maul

Patent number: 6264900Abstract: 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.Type: GrantFiled: May 5, 1998Date of Patent: July 24, 2001Assignees: Bayer Aktiengesellschaft, Forschungszentrum Karlsruhe GmbHInventors: Klaus Schubert, Wilhelm Bier, Gerd Linder, Erhard Herrmann, Bernd Koglin, Thomas Menzel, Christine Maul

Patent number: 6082891Abstract: 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.Type: GrantFiled: April 17, 1998Date of Patent: July 4, 2000Assignees: Forschungszentrum Karlsruhe GmbH, Bayer AGInventors: Klaus Schubert, Wilhelm Bier, Erhard Herrmann, Thomas Menzel, Gerd Linder

Patent number: 5803600Abstract: In a static micromixer for mixing at least two fluids including a flow guide structure having a longitudinal axis extending in the general flow direction of the fluids through the guide structure, separate fluid admission areas disposed at the entrance end of the flow guide structure and a mixing chamber disposed at the exit end of the flow guide structure, the flow guide structure is formed by foils of a thickness of about 100 .mu.m disposed on top of each other and having parallel grooves extending in one foil from one of the fluid admission areas at an angle with respect to the general fluid flow direction through the flow guide structure to the mixing chamber and in an adjacent foil from another of the fluid admission areas to the mixing chamber such that in the mixing chamber the fluid exits of different foils are disposed adjacent each other, the grooves having a width of less than 250 .mu.m and being spaced from each other by less than 70 .mu.Type: GrantFiled: October 9, 1996Date of Patent: September 8, 1998Assignee: Forschungszentrum Karlsruhe GmbHInventors: Klaus Schubert, Wilhelm Bier, Gerd Linder, Dieter Seidel

Patent number: 5249359Abstract: A method of producing a finely structured body which includes a plurality of stacked, cut sections of foil at least one of which is provided with grooves in a selected groove direction on at least one surface thereof, and which has a plurality of closely juxtaposed, channel-like perforations with high shape accuracy, true dimensions and high surface quality. The method includes: a. providing a vacuum clamping means comprised of a ground, sintered metal plate which is connected to a vacuum source and which is positioned on a work table which is movable in two mutually perpendicular directions X and Y; b. positioning a machinable foil on the ground, sintered metal plate and clamping the machinable foil thereto by applying an effective amount of vacuum; c.Type: GrantFiled: March 19, 1992Date of Patent: October 5, 1993Assignees: Kernforschungszentrum Karlsruhe GmbH, Messerschmidt-Bolkow-BlohmInventors: Klaus Schubert, Wilhelm Bier, Gerd Linder, Peter Schmid, Peter Bichler, Winfried Brunner, Wolfgang Simon

Patent number: 5152060Abstract: A method of producing a finely structured body comprised of a plurality of stacked, cut sections of foil at least one of which is provided with grooves. A machinable foil is wrapped around a cylindrical mandrel of a lathe to overlap opposing edges. The overlapped edges are clamped into an axial recess of the cylindrical mandrel by means of a clamping means and a plurality of grooves cut into the surface of the foil by means of at least one shaping diamond positioned in a feed which is finely adjustable. The plurality of grooves each have a groove length, a groove width, and a cross-sectional shape that is constant over the groove length and is freely selectable. Then, the grooved machinable foil is cut into cut sectoins and the cut sections are stacked. The plurality of grooves have a form precision such that, for groove lengths of more than 1000 .mu.m, the groove width has an accuracy of about .+-.1 .mu.m for land widths which equal or exceed about 15 .mu.m.Type: GrantFiled: May 31, 1991Date of Patent: October 6, 1992Assignees: Kernforschungszentrum Karlsruhe GmbH, Messerschmidt-Bolkow-BlohmInventors: Klaus Schubert, Wilhelm Bier, Gerd Linder, Peter Schmid, Peter Bichler, Winfried Brunner, Wolfgang Simon
