    Abstract: In a process for producing a stable, aqueous dispersion or a stable, water-dispersible dry xanthophyll powder: (a) a molecular disperse solution of at least one xanthophyll, if required together with an emulsifier and/or an edible oil is produced in a water-miscible organic solvent or in a mixture of water and a water-miscible, organic solvent, at temperatures above 30 DEG C; (b) this solution is mixed with an aqueous solution of a mixture of protective colloids; (b1) the mixture containing at least one low molecular protective colloid component and at least one high molecular protective colloid component whose molecular weights differ by at least 10,000; (b2) the solvent component being converted into the aqueous phase and the hydrophobic phase of the xanthophyll being produced as a nanodisperse phase; and (c) if required, the thus obtained dispersion is freed from solvent and water to produce a water-dispersible dry powder and dried, if required in the presence of a coating material.

    Abstract: 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).

    Abstract: A process for the preparation of finely divided acicular and pore- free alpha -Fe2O3 from iron (III) salts in the presence of at least one organic substance forming complexes with iron (III) ions in alkaline suspension at temperatures between 80 and 250 DEG C and its use for the preparation of magnetic materials suitable for magnetic recording media.

    Abstract: The optical fibre sensor measures the Doppler shift of dispersed laser light using a quasi-elastic light scattering principle, where the light is dispersed by incidence with moving particles. The exit face (7) for the laser light is provided at the end of a monomode or multi mode optical fibre (3) acting as an immersion probe, with an angle of between 0 and 15 degrees and pref between 1 and 6 degrees between the optical axis (8) of the optical fibre (3) and the normal (9) to the exit face (7). Pref. the dispersed light is fed back to the optical fibre (3) via the exit face (7) for coupling to a detector (12), pref. with an associated signal processing circuit.
