Abstract: A mixer system for mixing at least two fluids includes a plurality of micromixers that are fluidically connected in parallel. The micromixers are integrated into a guide matrix and are fluidically connected via feed lines for the fluids to be mixed.

Abstract: In a method of producing a self-focusing reflection grating structure for the series manufacture of microspectrometers including flexible foil strips provided with a grating structure and supported in a microspectrometer housing, a foil is first mounted onto a support member of an ultraprecision turning lathe on which circumferential parallel grooves are cut into the foil by microforming diamonds providing a saw-tooth pattern of annular teeth with predetermined tooth spacing, the foil is then cut into a plurality of foil strips and the strips are bent into a curved shape providing a focusing reflection grating structure.

Abstract: There are disclosed and claimed novel polyamides on the basis of a) 1,3-bis-(amino-methyl)-cyclohexane or mixtures thereof with 1,4-bis-(amino-methyl)-cyclohexane; b) one or several aromatic dicarboxylic acid (s); and c) one or several aliphatic amino-carboxylic acid(s); and the process of making the same. These polyamides combine high transparency with very good thermal and mechanical properties, namely high second order transition temperatures, good form stability at higher temperatures, high hardness and impact strength.
