Abstract: The invention relates to compounds based on merocyanines with the general formulas I and/or II, where n=0 or an integer from 1 to 3, X=O or S and the residues R1 to R12 are the same or different and signify in particular hydrogen or various organic residues, without or with functional groups, and R2 incorporates an amine function. The compounds in accordance with the invention are suitable as fluorescent dyes (fluorophores) for used in optical determination and demonstration methods, in particular those employing fluorescence, for example in medicine, pharmacology and the biological, materials and environmental sciences. They are characterized by high photostability and long storage life, and exhibit a high fluorescence quantum yield. Excitation causing them to emit light can be achieved in a simple manner, by white-light sources or by laser irradiation in the UV, visible or NIR spectral region.

Abstract: In a method for the hydro-erosive rounding of an edge of a part, particularly an edge in a duct of a high pressure-resistant part, and a use thereof, a liquid to which abrasive elements are added is directed along the edge that is to be rounded. In order to optimize the result of the rounding process, a high-viscosity liquid is used as a liquid (10). The inventive method is used for rounding parts of a fuel injection system.

Abstract: An electrode guide and a method for the spark-erosion of workpieces are disclosed. The electrode guide (1), consisting of a two-piece prism-shaped (2, 3) guide with a pretensioning device (6), enables an electrode (4) to be guided in a play-free manner, thus allowing the production of bores that is accurate to within 1 ?m. A pivoting device (10) for pivoting the electrode guide and an alignment device (14) for the parallel displacement of the electrode guide (1) are also provided, enabling the production of conical bores.

Abstract: A device for transferring a thrust, a fuel injection valve with such a device, and a method for manufacturing such a thrust transferring device. To transfer the thrust of an actuator, especially in an injection valve, mechanical tappets are used, which have substantially the shape of a cylinder whose defining surfaces are substantially triangular, with the corners rounded. By the great width of the tappet, broad contact areas are created so that friction during the transfer is reduced.
