Abstract: In a process for producing a pulverulent product from a liquid substance or mixture of substances, the liquid substance or mixture of substances to be pulverized is first provided in a pressure vessel. A gas is then dissolved under elevated pressure in the liquid substance or mixture of substances. The resulting liquid/gas solution is then conducted out of the pressure vessel and to an expansion element, through which it is passed and rapidly expanded. Upstream of the expansion element, in the expansion element or downstream, in particular just downstream, of the expansion element, a solid pulverulent auxiliary is admixed. In this manner, a stable pulverulent product results from the solution or from the substance or mixture of substances.

Abstract: A process for the preparation of a stable, homogenous extract of plants or plant parts is disclosed. The process comprises mixing and extracting the plants or plant parts charged in a fresh and/or dried state with at least one solvent and at least one agent (having various disclosed properties), then filtering insoluble compounds to obtain a filtrate which is substantially free of secondary reaction products and contains a native compound mixture. The filtrate is concentrated to a spissum extract and the pressure used for the concentration is adjusted according to the vapor pressure of the solvent(s).

Abstract: A device and an evaluation procedure for the depth-selective, non-invasive detection of the blood flow and/or intra- and/or extracorporeally flowing liquids in biological tissue are described whereby photons of a coherent, monochromatic source of light are entered into the tissue through a first area, photons reemerging from the tissue at different distances from this first area are detected with respect to their frequency and number, or intensity, and, from this information, i.e. frequency and/or number, or intensity, and/or reemerging location, conclusions about the relative modification of the flow amount and/or speed and/or location of the blood flow and/or the intra- and/or extracorporeally flowing liquids in the tissue are drawn with the help of an evaluation program or algorithm.

Abstract: A process for the removal of undesired lipophilic contaminations and/or residues, which are contained in beverages or in vegetable preparations. The process comprises a first step in which a beverage or vegetable preparation is mixed with a lipophilic phase such that the contaminations and/or residues to be removed are dissolved in the lipophilic phase and are concentrated therein nearly quantitatively. In a second step, the lipophilic phase, which contains the contaminations and/or residues, is separated from the beverage or vegetable preparation. Finally, the purified beverage or vegetable preparation is obtained.

Abstract: A device for shaping the cornea of an eye, including a laser (1), the laser beam of which has a circular mode of distribution, and a beam-shaping device and a beam-guiding device, which direct the laser beam onto the cornea. To homogenize the energy density over the cross section of the beam, the beam-shaping device is provided with a focusing optic which focuses the laser beam, a diffraction element which is disposed at a short distance from the focus plane of the focusing optic and the diffraction maxima of which interfere with the minima of the mode of distribution, and an image-field diaphragm which is disposed at a site which is optically conjugate to the cornea.

Abstract: Pesticide-poor concentrates of active components of plants are obtained in that in a first step plants or parts thereof, which may be charged in fresh or dried state, are extracted with at least one polar solvent at a measured pH-value in the range from 3.2 to 9.8 in such a way, that in the obtained primary extract are contained mainly the desired plant components, accompanied by undesired plant components, accompanying substances and pesticides, in a second step said primary extract is contacted with adsorber resin(s) in such a way, that on one hand the desired plant components are adsorbed thereon, and on the other hand the solution with the undesired plant components, the accompanying substances and pesticides are separated from the charged resin, in a third step the desired plant components are desorbed from said resin with at least one solvent, and in a fourth step the solvent(s) is (are) removed either partially or completely, and by this way a concentrate of active components is obtained.

Abstract: Process for separating and purifying substances by crystallization from the melt under high pressuresIn the process for separating or purifying substances by crystallization from melts or highly concentrated solutions under high pressures, gas is dissolved in the melt to be crystallized and is expelled again after the crystallization with reduction in the pressure. Still adhering or occluded impurities are thus removed.

Abstract: In the process for separating and purifying substances by crystallization from the melt under pressure, the melt is subjected to pressure under an inert gas atmosphere and then cooled, whereupon it crystallizes. The residual melt is separated from the resulting crystals, after which the crystals are degassed by reducing the pressure and are caused to sweat, and the sweat oil is separated off.
