Patent number: 10463053Abstract: 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.Type: GrantFiled: July 31, 2018Date of Patent: November 5, 2019Assignee: UPFIELD US INC.Inventors: Frank Emile Wubbolts, Cynthia Akkermans, Tjerk De Vries, Ernst Jan Siewers, Daniela Oana Trambitas, Rolf Sebastiaan Wilms

Patent number: 9752273Abstract: 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.Type: GrantFiled: June 24, 2015Date of Patent: September 5, 2017Assignee: CO2Nexus, Inc.Inventors: Guy Robert Babbitt, Andrew Timothy Maxey, Ernst Jan Siewers, Stuart Parker, Nicholas Paul Echter

Patent number: 9518355Abstract: 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.Type: GrantFiled: June 28, 2013Date of Patent: December 13, 2016Assignee: HUNTSMAN TEXTILE EFFECTS (GERMANY) GMBHInventors: Harald Chrobaczek, Günther Tschida, Tanja Refle, Ernst Jan Siewers

Publication number: 20150247277Abstract: 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.Type: ApplicationFiled: March 10, 2015Publication date: September 3, 2015Applicant: CO2NEXUS, INC.Inventor: Ernst-Jan Siewers
