  • Patent number: 10308479
    Abstract: An example elevator system may include a shaft in which at least one elevator car can be vertically displaced. The elevator car may be coupled to a counterweight via a cable arrangement wherein the cable arrangement has at least one cable portion. Horizontal deflection of the cable portion can be limited by at least one limiting member. In some examples, the at least one limiting member may be configured as a limiting roller that is mounted laterally alongside the cable portion such that it can be rotated about an axis of rotation and can be made to rotate by a controllable rotary drive that depends on a speed and a movement direction of the cable portion.

  • Patent number: 10017466
    Abstract: The present invention relates to a process for purifying the xanthophylls astaxanthin and canthaxanthin. The process comprises suspending the xanthophyll in an organic solvent or solvent mixture, treating the suspension of the xanthophyll in the organic solvent or solvent mixture at elevated temperature, and subsequent separation off of the xanthophyll from the solvent by a solid-liquid separation, wherein the organic solvent is selected from ketones of the general formula (I) and mixtures of ketones of the general formula (I) where R1 is C1-C4 alkyl and R2 is selected from C1-C6 alkyl, C3-C8 cycloalkyl, phenyl and benzyl, wherein the phenyl rings in the two last-mentioned radicals are unsubstituted or can have 1 or 2 methyl groups, or R1 and R2 together are linear C4-C6 alkylene, which can bear 1, 2 or 3 methyl groups as substituents.

  • Publication number: 20180110741
    Abstract: The present invention relates to astaxanthin compositions for use in foodstuffs, food supplements or feedstuffs or as a medicament. Astaxanthin compositions which comprise up to at least 50% by weight, in particular at least 60% by weight, particularly at least 70% by weight, specifically at least 80% by weight or at least 90% by weight, based on the total weight of astaxanthin and astaxanthin derivatives in the composition, of an astaxanthin monoester with an aliphatic, unbranched C10C22-monocarboxylic acid have a particularly good bioavailability when at least 90% by weight of the monoester present in the astaxanthin composition is a monoester with precisely one aliphatic, unbranched C10-C22-monocarboxylic acid. They are therefore particularly suitable for the use in foodstuffs, food supplements or feedstuffs and for the therapeutic use as medicament and as constituent for medicinal preparations and pharmaceutical compositions.
