摘要:
A tool comprising a cutting section on which a multiplicity of blades or cutting edges and flutes are formed; a shank section, which forms a chucking section on a side which faces away from the cutting section, wherein a number of fluid channels which corresponds to the number of flutes is formed in the chucking section in such a manner that the fluid which emerges from axial discharge openings of the chucking section can be fed in a free jet along the shank into in each case one associated flute of the cutting section. Also, a method for supplying the blades of such a tool.

Components for static micromixers, micromixers constructed from such components and processes carried out by the use of said micromixers are described. The components are in the form of a disk with at least one inlet opening (2) for introducing at least one feed stream into a linking channel (3) disposed in the plane of the disk and at least one outlet opening (4) for the outflow of the feed stream into a mixing zone (5), wherein the inlet opening (2) is connected in a communicating manner with the outlet opening (4) through the linking channel (3) disposed in the plane of the disk and wherein the linking channel (3) before opening into the mixing zone (5) is divided by microstructure units (6) into two or more part channels, the widths of the part channels being in the millimeter to submillimeter range and being smaller than the width of the mixing zone (5).The micromixers can be used for mixing, homogenizing, dispersing, emulsifying, dissolving or gassing liquids or for carrying out chemical reactions and particularly combustion reactions.

A process is described for the extraction of one or more substances from a fluid starting material with an appropriate extraction agent by use of a static micromixer for mixing the starting material with the extraction agent. The static micromixer is provided with disk-shaped components, the disk (1) being provided with at least one inlet opening (2) for introducing at least one fluid stream into a linking channel (3) disposed in the plane of the disk and at least one outlet opening (4) for removing the fluid stream into a mixing zone (5) disposed in the plane of the disk, the inlet opening (2) being connected with the outlet opening (4) in a communicating manner through a linking channel (3) disposed in the plane of the disk, and the linking channel (3) before opening into the mixing zone (5) being divided by microstructure units (6) into two or more part channels (7), and the widths of the part channels being in the millimeter to submillimeter range and being smaller than the width of the mixing zone (5).

摘要:
In a method of manufacturing metallic or ceramic microparts using a three-dimensional body formed by first and second polymer fractions in a two-component injection molding process, wherein one of the polymer fractions comprises an electrically non-conductive polymer and the second an electrically conductive polymer, the polymer fraction used for the first injection molding step has a higher melting point than the polymer fraction used in the second injection molding step and the metal micropart is formed by galvanic deposition of a metal from an electrolyte and the ceramic micropart is formed by electrophoretic deposition of ceramic material from a ceramic suspension or colloid on the electrically conductive polymer fraction surface of a substrate surface of the interim body.
摘要:
A rotating shaft tool has a base body, with a guide slot in the base body, in which at least one elongate cutting blade can be arranged. An axial adjustment means which can be arranged at the mouth of the guide slot and by means of which the cutting blade can be adjusted axially in the guide slot. At least one spherical force exerting element, capable of moving the cutting blade in the axial direction, can be arranged at one end face of the cutting blade. Its axial displacement can be adjusted by means of at least one second force exerting element which deviates from the direction of movement of the first spherical force exerting element.
摘要:
The packaging system has two storage chambers for separately storing two components and a static micromixer for mixing them to prepare a formulation. The static micromixer is provided with plural disks (1) arranged in a stack. Each disk (1) has at least one inlet opening (2) for a feed stream, which is connected via a linking channel (3) with at least one outlet opening (4) for outflow of the feed stream into a mixing zone (5). The linking channel (3) is divided into two or more part channels (7) by microstructure units (6). Each part channel has a respective width that is smaller than a width of the mixing zone (5). A method of in-situ preparation of a formulation by mixing the components in the packaging system is also described.

An apparatus (1) to remove one individual hair/fiber (2) at a time from a tuft (3) using a gripping device (4), which has a first and a second opposing gripping element (5, 6). The first and the second gripping elements (5, 6) are relatively moveable with respect to one another, wherein the first gripping element (5) has a wedge-shaped groove (7) oriented towards the second gripping element (6) and the second gripping element (6) has an essentially flat counterpressure zone (8), and wherein the first gripping element (5) is tapered on the side of the wedge-shaped groove (7) (taper A) (FIG. 2).
