  • Patent number: 10161557
    Abstract: Cryogenic fluid transfer line comprising a tubular outer jacket housing at least two interior fluid-transfer tubes and a heat shield forming an insulating wall arranged around the interior tubes, the outer jacket comprising a lateral pumping opening connected to a pumping member intended to pull a vacuum in the outer jacket, characterized in that the heat shield comprises an orifice situated adjacent to the opening and an optical cover, the optical cover being positioned facing the orifice and in a plane distinct from that of the wall of the heat shield so as to prevent or limit direct thermal radiation from the outer jacket toward the interior tubes.

  • Publication number: 20180105777
    Abstract: A beer composition including a hydration additive is described. The hydration additive includes a coconut extract and a salt additive. The beer composition may provide a hydrating effect or a feeling of hydration upon consumption. The coconut extract may be in the form of a frozen coconut concentrate that can be diluted with water to form a coconut solution. The coconut solution may be added during the brewing process together with the salt additive in a mixture or may be added separately or sequentially. Typically, the salt additive is in the form of sodium chloride and may contain other optional salts.

  • Patent number: 9631185
    Abstract: Fusion-proteins containing an enzyme, preferably a feed or food enzyme, coupled to a gut surface-binding domain are presented. The fusion-proteins can be used to promote feed utilization in animals. In a particular example, a Fusion enzyme according to the invention comprising a gut-surface-binding polypeptide segment linked to a phytase show an increased resident time in the gut, which leads to an increased amount of time given to the enzyme to catalyse the corresponding reaction which finally leads to improved feed utilisation.
