    摘要: The invention relates to a process and an apparatus for producing stably fine-particle powders. The invention starts from a process for producing stably fine-particle powders in which one or more substances A and one or more substances B are dissolved in supercritical fluids, and the solutions are decompressed along a holdup section. In the process, substances A and B are each dissolved in separate supercritical compressible fluids, and the holdup sections interpenetrate, with the solubility limit of A in the appropriate fluid being exceeded at an earlier time than is the solubility limit of B in the appropriate fluid.

    摘要: The invention seeks to provide a free-flowing formulation of one or more disperse dyes, with which packages can be dyed homogeneously by the HT process without filtering out of the dye, and which is suitable for the thermosol dyeing process. According to the invention such a formulation comprises one or more disperse dyes (a) enclosed in a matrix of one or more polymers (b) which are soluble, or colloidally soluble, both in water and in an organic solvent, in the form of a solid solution in a state of molecular dispersion or of extremely fine subdivision so that in an X-ray spectrum the dye appears amorphous.The formulations may contain additional assistants conventionally present when dyeing hydrophobic fibers. The formulations contain the disperse dye in an extremely fine state of subdivision. Because of the latter, the formulations give level package dyeings, without filtration of the dye, and very level dyeings when used by the thermofixing process.

    摘要: In a fiber-optical Doppler anemometer for measurement of fluctuating light or the Doppler broadening of laser light scattered by a scattering medium, for example by particles in motion, coherent laser light is passed via a fiber-optical coupler (1) and a submerged fiber-optical probe (2) into the scattering medium, and the light scattered back by the scattering medium is picked up by the submerged fiber-optical probe (2), branched by the fiber-optical coupler (1) and passed to a photodetector (3).

    摘要: Rapid in situ estimation of the degree of dispersion in flowing two-phase systems, in particular for determining optimum metering of dispersants or flocculants in concentrated dispersions, is carried out by a method in which assignment of the degree of dispersion is effected by measuring the pressure drop experienced by a flowing dispersion along a defined length during tubular flow.
