    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: Preparation of stable fine particle powders comprises: (a) dissolving one or more substances (A) and one or more substances (B) in a super-critical, compressible fluid; and (b) relaxing the fluid along a residence path, where the solubility limit of (A) is earlier than that of (B) in the residence path. An Independent claim is included for an apparatus for carrying out the process comprising a first high pressure autoclave (2) for dissolving substance (A) in a super critical fluid and a second high pressure autoclave for dissolving substance (B) in a super critical fluid. Two separate feeds (3, 7) connected to relaxation devices (4, 8) relax both fluids so that their flows intersect.

    Abstract: The method for chemically differential imaging using a scanning force microscope uses chemically modified samples, where the imaging is in normal force, elasticity or tapping/non-contact mode. A detector (1), laser source (2), piezoelectric adjuster (3), tip and lever arm (4) are used to evaluate the sample (5). The scanning tip is either a metal or oxide layer, or it may be coated with one or more substances, such as thiol groups with additional acid or base functions, thiol with nuclein base, disulphide with acid base or nuclein base.

    Abstract: Method for the continuous preparation of beta -carotene solubilisates by brief heating of beta -carotene together with an emulsifier until solution takes place, rapid cooling of the homogeneous solution to below 100 DEG C by addition of water and subsequent adjustment of the required final concentrations of beta -carotene, which is characterised in that a suspension, which has been preheated to 20 to 80 DEG C, of 1 to 40% by weight beta -carotene in an emulsifier is pumped through a heating coil located in a heat-transfer oil, where the temperature in the solubilisation mixture is 120 to 180 DEG C and the residence time is 10 to 300 seconds, and the homogeneous solution is turbulently mixed in a mixing chamber with such quantities of water at 10 to 80 DEG C that a solubilisate containing 0.5 to 6% by weight beta -carotene is produced and is, where appropriate, further diluted to the required final concentration.

    Abstract: Pharmaceutical compsns. in aq. liq. or water-dispersible powder form contain a soln. of a water-insol. drug (I) in an edible oil or fat (II) in microdisperse form, together with an emulsifier (III) and a protective colloid (IV). The compsns. comprise (dry basis) 0.5-34% (I), 2.5-68% (II), 5-50% (III), 0.1-30% (IV), 0-70% plasticiser and 0-60% of one or more additives. The dia. of the oil-phase particles is less than 0.5 micron. (I) is a cpd. with a positive logarithmic octanol/H2O partition coefft., e.g. anipanil, propafenon, rilapin, nesapidil, verapamil, nonipamil, biperidin, kawain, ibuprofen, mefloquin, diazepam, carbamazepin, Na cromoglycate or amonafide.

    Abstract: Preparation of pulverulent water-dispersible carotenoid preparations in which the carotenoid is present dissolved in an edible oil and the oil solution is present in the form of small droplets, by rapidly dissolving a carotenoid in a volatile, water-miscible, organic solvent at between 50 and 240 DEG C together with from 1.5 to 20 times the weight, based on the carotenoid, of an edible oil and also an emulsifier, under atmospheric or superatmospheric pressure, immediately mixing the resulting molecularly dispersed solution with an aqueous solution of a protective colloid at between 0 DEG C and 50 DEG C to transfer the hydrophilic solvent component into the aqueous phase, forming the hydrophobic oil phase, which contains the carotenoid in solution, as a microdisperse phase, and stripping the resulting two-phase mixture of solvent and water in a conventional manner.
