  • Patent number: 5523420
    Abstract: A process for preparing .alpha.-tocopherol or tocopheryl acetate by cyclocondensation of trimethylhydroquinone with phytol or isophytol in the presence of an acid catalyst and of a solvent and, where appropriate, subsequent acetylation, which comprises carrying out the cyclocondensation and, where appropriate, the subsequent acetylation in liquid or supercritical carbon dioxide as solvent.

  • Patent number: 5422256
    Abstract: A strain of Bacillus subtilis which is a tryptophan auxotroph, resistant to sulfaguanidine and flourotryptophan and produces anthranilic acid in a nutrient solution containing L-tryptophan, and process for the preparation of anthranilic acid by fermentation.

  • Patent number: 5402946
    Abstract: A process for exploiting plastic wastes arising in the production or further processing or after use of the plastic, by, in a sewage treatment plant, comminuting the plastic wastes then mixing them with a sewage sludge to which organic flocculants are added with or without the addition of further amounts of finely divided coal and/or ash, if appropriate, modifying the surface properties of the plastic with binders in such a way that it binds better into the sludge, filtering the pretreated sludge mixture, where the plastic can assume the properties of a filtration aid, i.e. the filtering residue is reduced, incinerating the resulting filter cake, where the plastic assumes the function of an additional energy source and depositing the ash for example in a sanitary landfill or exploiting it.

  • Patent number: 5169759
    Abstract: Riboflavin is removed from fermentation suspensions by them being heated at from 50.degree. to 90.degree. C. for from 1 to 3 hours, than cooled to from 0.degree. to 30.degree. C. over a period of from 1 to 5 hours, and subsequently being centrifuged to give a sediment fraction and liquid fraction in such a way that the sediment fraction contains predominantly riboflavin crystals as solid, and the liquid fraction contains virtually no crystalline riboflavin, and, where appropriate, resuspending the sediment fraction in from 0.5 to 2 parts by volume of water per part by volume of sediment fraction and repeating procedure c.

  • Patent number: 4977190
    Abstract: Riboflavin produced by a microbial method is prepared in the form of free-flowing, non-dusting, spray-dried granules or microgranules as a feed additive by removing water from the mixture discharged from microbial fermentation for the preparation of riboflavin, wherein the mixture is subjected to(a) a fluidized-bed spray-drying process(b) a one-material spray-drying process or(c) a disk spray-drying process without significant amounts of binders being added to the discharged fermentation mixture.

  • Patent number: 4658884
    Abstract: A tubular mold is included in a coolant container there being a tubular guide sheet arranged around the mold at a certain distance therefrom, the coolant flows through the gap between the mold and the guide sheet; as specific improvement the upper portion of the mold has grooves cut into the outside to be flown though by water offering therefore a relatively enlarged cooling surface as compared with the remainder of the configuration of the mold underneath, the guide sheet has a radially inward extension such that water is forced into and through the grooves; these grooves are provided in the area in which the liquid bath level is expected to occur in the mold.

  • Patent number: 4651937
    Abstract: A light wave conductor or fiber optics is withdrawn from the peripheral groove of a rotating storage disc using a deflection pulley or the like rotating in a plane that runs tangential to a circle through the middle of the groove, a pivotal guide lever for the fiber conductor serves as input for speed control of the disc drive. In case of plural withdrawal equipment, the discs are vertically staggered and overlap.

  • Patent number: 4056801
    Abstract: Apparatus for locating sources of sound in water, including a hydrophone system which is suspended from a buoy after being dropped into the water and whose one given reference axis is automatically aligned with the magnetic field of the earth by mechanically coupling the hydrophone system with a compass magnet (north reference). The hydrophones of the hydrophone system are electrically connected with a switching or control box by means of transmission wires which are insulated with an elastic plastic and pass freely through the water and the hydrophone system is mechanically fastened to the switching box to be rotatable in a recoilless manner about an axis which is perpendicular to the surface of the earth. The control box is in turn connected to the buoy by means of an elastic suspending cable and an electrical connecting cable.
