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.

Abstract: In a laser-optical arrangement for producing signals by light scattering, obscuration or reflection, from flowing particles and/or groups of particles, which are recorded, as time-dependent voltage/current fluctuations, by means of a photodetector (9) via appropriate imaging optics (7,8,18), assignment to the degree of dispersion of the flowing system is based on a subsequent measurement (10) of the root-mean-square value, and, according to the invention, the sample stream (1) is separated from a transmitter (6,7,18) and a receiver (8,9,10) by an enveloping stream (4), and the transmitter side consists of an individual light-transmitting fiber (7) provided with a means for parallel or focused emergence of a light bundle having a diameter of the order of magnitude of the particles and/or groups of particles.

Abstract: The use of organosulfur compounds is claimed for bathochromic shifting of the UV/visible absorption spectrum of carotinoids. Independent claims are included for: (A) complexes comprising one or more organosulfur compounds and one or more carotinoids, and (B) preparation of carotinoid formulations, which comprises dispersion of an organosulfur/carotinoid mixture in water or a protective colloid solution, followed by drying of the dispersion.

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 uses a laser light source (1) for illuminating the sample (10), with detection of the Raman dispersed light and division into its spectral lines via a grid spectrograph (6). The intensity of at least one spectral line is measured at least 10 times per second using a photodetector (8), with fluctuation analysis, autocorrelation, or frequency analysis of the measured intensity values.

Abstract: A novel encapsulated fertiliser granulate (I) is obtained by applying to a starting fertiliser granulate (II) aqueous solutions containing (a) a polyelectrolyte (PE) and (b) oppositely charged polyvalent ions (MI). Also claimed is a fertilisation method involving applying (I) to agricultural land. Preferably PE has a solubility in water, at 20 deg C and pH 1-14, of at least 0.1 g per litre. MI consists of alkaline earth metal, zinc, aluminium or iron ions; and/or a second polyelectrolyte (PE') having the opposite charge to PE. PE and MI are especially both bio-polymers. (II) is optionally further treated with (c) a polyfunctional compound (V) which reacts with PE or MI to form at least two bonds, during or in combination with application of (a) and (b); and/or (d) an aqueous dispersion of an optionally salified copolymer if 75-90 wt.% ethylene and 10-25 wt.% alpha -olefinically unsaturated 3-8C carboxylic acid, before or in combination with application of (a) and (b), specifically such that the amount of copolymer is 1-50 wt.% based on PE and MI.
