    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: Disclosed is the polyelectrolytic titration of serum lipoproteins, the negative surface charge of the latter being determined quantitatively by adding an excess amount of a polycation in aqueous solution to the particular serum lipoprotein and then back-titrating the positive charge, of the polycation, which has not been neutralized by the negative surface charge, against a chromotropic polyanion, in the presence of a metachromatic dye as the indicator. The method according is used for the diagnosis of lipometabolic disorders.

    摘要: A process for the continusous preparation of Beta-carotene together with an emulsifier by briefly heating Beta-carotene together with an emulsifier to give a homogeneous solution, rapidly cooling the latter to below 100.degree. C. by adding water, and subsequently adjusting to the required final concentration of Beta-carotene, comprises pumping a suspension, which has been preheated from 20.degree. to 80.degree. C., of 1 to 40% by weight of Beta-carotene in an emulsifier through a heating coil located in a heat transfer oil, where the solubilization mixture is at from 120.degree. to 180.degree. C. and the residence time is from 10 to 300 seconds, and subjecting the homogenous solution to turbulent mixing in a mixing chamber with an amount of water at from 10.degree. to 80.degree. C. to result in a solubilizate which contains from 0.5 to 6% by weight of Beta-carotene and is, if necessary, diluted to the required final concentration.

    摘要: Finely divided, pulverulent carotinoid or retinoid compositions, in which the carotinoid or retinoid essentially has a particle size of less than 0.5 micron, are prepared by a process wherein a carotinoid or retinoid is dissolved in a volatile, water-miscible, organic solvent at from 50.degree. C. to 200.degree. C., if necessary under superatmospheric pressure, within the space of less than 10 seconds. The carotinoid is immediately precipitated, in a colloidally disperse form, from the molecularly disperse solution by rapidly mixing the latter with an aqueous solution of a swellable colloid at from 0.degree. C. to 50.degree. C., and the resulting dispersion is freed from the solvent and the dispersing medium in a conventional manner.
