  • Patent number: 10463053
    Abstract: Disclosed is a novel method of making a structuring agent for edible dispersions such as margarines or spreads. Fat, or another structuring component, is subjected to a process involving mixing it with liquefied gas or supercritical gas, and expanding the mixture through an orifice. In the invention, water is added to the mixture prior to expansion, so as to provide a spray liquid in the form of a fat and water emulsion.

  • Patent number: 9752273
    Abstract: A densified fluid barrier cleaning system is disclosed in which a pressure vessel encases a movable basket positioned so as to cross a barrier such that one opening of the pressure vessel resides in a first environment and a second opening of the pressure vessel resides in a second environment. A tubular basket within the pressure vessel is positioned such that its central longitudinal axis is aligned with both the first and second opening of the pressure vessel. Responsive to the successful completion of a cleaning cycle, soiled articles that are introduced to the basket via the first opening from the first environment can be removed through the second opening and into the second environment thus bridging the barrier without fear of introducing contaminants from the first environment to second environment.

  • Patent number: 9518355
    Abstract: Compositions comprising a specific ethoxylated/propoxylated product as well as an alkylene carbonate, an epoxysilane or a polysiloxane are useful for dyeing or finishing fibrous materials. Reaction products formed from said products are also very useful for these purposes. Said products are preferably used as solutions in supercritical carbon dioxide.

  • Publication number: 20150247277
    Abstract: A dry cleaning system arranged for washing articles employing a cleaning solution. The dry cleaning system includes awash tank (2) for washing an article to be washed with a cleaning solution. The wash tank (2) is arranged for washing the article at an increased pressure compared to atmospheric pressure. The dry cleaning system includes a fluid displacement device (1), such as a pump, connected to the wash tank (2) and is arranged for transferring the cleaning solution through the dry cleaning system in a first operational mode. The fluid displacement device is arranged to reduce the pressure in the wash tank towards atmospheric pressure in a second operational mode.

  • Patent number: 8569049
    Abstract: The invention provides a photo bioreactor (1) comprising a vessel (10) containing an aqueous liquid comprising a photosynthetic culture and a light distributor (30). The light distributor has a surface (31) arranged to receive light (40) and a tapered surface (32) arranged to emit at least part of the received light. At least part of the tapered surface. (32) is submerged in the aqueous liquid comprising the photosynthetic culture. Light may be distributed efficiently in the aqueous liquid comprising the photosynthetic culture by relatively simple and cheap means. The reactor allows a high illuminated volume fraction.
