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.
Abstract:
A pressurized system using densified fluid can apply and/or activate durable water repellant. Durable water repellant bound to fibers of an article of clothing can be activated by first removing contaminants via a pressurized densified fluid cleaning process and thereafter imputing energy into the durable water repellant via the article's interaction with the densified fluid and its gaseous rinse cycle.
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.

Abstract:
A densified fluid barrier cleaning system (100) is disclosed in which a pressure vessel (110) encases a movable basket (120) positioned so as to cross a barrier (210) such that one opening (220) of the pressure vessel resides in a first environment (225) and a second opening (230) of the pressure vessel resides in a second environment (235). A tubular basket (120) within the pressure vessel is positioned such that its central longitudinal axis is aligned with both the first (220) and second (230) opening of the pressure vessel (110). Responsive to the successful completion of a cleaning cycle, soiled articles that are introduced to the basket (120) 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.
Abstract:
A direct contact densified fluid-based thermodynamic treatment system uses the fluid to effect heat transfer as the working fluid in a separate yet linked treatment system. During certain phases of operation of a densified fluid-based treatment process wherein it is necessary to distill the fluid to maintain the purity of the densified fluid heat is imparted to the densified fluid raising it above the boiling point for the associated pressure within a vessel. A densified fluid-based refrigeration/thermodynamic system removes heat during the condensing cycle of a working densified fluid treatment system and use the removed heat for distillation of the same working fluid in the distillation vessel. The process does not require an external heating or cooling system, and thus can be entirely supported by a single machine using the same densified fluid during its operational phase.
