Patent number: 7780767Abstract: A condenser and a containment vessel adapted to efficiently condense a gas out of a mixture of condensing and non-condensing gases. In condensers, the fraction of gas within a condenser made up of non-condensing gases can be significantly reduced by withdrawing gas from localised regions of relatively low temperature where the mass fraction of non-condensing gases will be relatively high. In containment vessels, pressures can be reduced by providing a large surface area of the liquid into which the condensing gas condenses in a relatively cool region of the containment vessel. Both these effects result from an appreciation of the manner in which non-condensing gases tend to accumulate in regions which are relatively cold.Type: GrantFiled: April 7, 2004Date of Patent: August 24, 2010Inventor: James Andrew Robinson

A first position includes a standby position wherein the enclosure and the damper arrangement block access to the interior volume. Another position includes a pressure-relief position wherein the interior volume is open to a continuous airflow path through the container. In some arrangements, there is an evacuation position wherein the damper arrangement allows access to the interior volume and blocks a continuous airflow path through the container. A gas turbine intake system includes a hood, a filter arrangement downstream of the hood and a collection hopper. The collection hopper is in airflow communication with an upstream side of the filter arrangement and downstream of the hood. The collection hopper includes a standby position and a pressure-relief position. A method of filtering air includes drawing air into a hood and then into a filter arrangement.Type: GrantFiled: November 30, 2004Date of Patent: November 20, 2007Assignee: Donaldson Company, Inc.Inventors: Dominique Renwart, Michael Handley, Herman Vanormelingen

Patent number: 7279020Abstract: Axial flow demisting cyclone for separation of a mixture of gas and liquid including an inlet 30 for gas containing liquid droplets and an outlet 31 for substantially dry gas, including a mainly cylindrical cyclone tube 16 with at least one path of slots or perforations 19 allowing a part of the fluid, including separated liquid, to flow out of the cyclone tube 16. The demisting cyclone also includes a swirl inducing device 17, 18 to set the entering fluid in rotation. This swirl-inducing device is formed from a cascade of vanes 18 attached to a concentric core body 17, preferably cylindrical in shape, which extends towards the wall of the cyclone tube 16, the vanes 18 being in the longitudinal direction of the vanes from their leading edge 23 to their trailing edge 24.Type: GrantFiled: November 7, 2002Date of Patent: October 9, 2007Assignee: ConSept A/SInventors: Bjorn Christiansen, Knut Sveberg, Inge Hjelkrem, Dag Kvamsdal

Patent number: 7186283Abstract: A cyclonic vacuum cleaner includes a separating unit for separating dirt and dust from a dirt-laden airflow which is drawn in by the cleaner. The separating unit has a chamber with a collection area for collecting dirt and dust which is separated from the airflow. A base of the separating unit is movable between a closed position in which the closure member seals the chamber and an open position by operation of a releasing means. The releasing means is inhibited from releasing the base when the unit is stowed on the chassis of the cleaner.Type: GrantFiled: January 24, 2002Date of Patent: March 6, 2007Assignee: Dyson Technology LimitedInventor: Remco Douwinus Vuijk

Patent number: 7182804Abstract: An arrangement for separating a hydrophobic liquid phase from a gaseous stream includes a coalescer filter, a housing, a gas flow direction arrangement, and a liquid collection arrangement. The coalescer filter includes a non-woven media of fibers. The housing includes an interior having a gas flow inlet and a gas flow outlet. The liquid collection arrangement is positioned within the housing construction and is oriented for receiving liquid collected from the coalescer filter and drained therefrom.Type: GrantFiled: February 7, 2005Date of Patent: February 27, 2007Assignee: Donaldson Company, Inc.Inventors: Steven S. Gieseke, Robert A. Dushek, Carolyn J. Finnerty

Patent number: 7165942Abstract: The disclosure relates to a fan impeller including a base plate and a plurality of fan impeller blades fixed to the plate. The fan impeller blades are positioned in an essentially vertical manner on the base plate and have a substantially radial arrangement, each fan impeller blade including a front edge facing radially outwardly that is substantially perpendicular to the base plate, a rear edge facing radially inwardly that is substantially perpendicular to the base plate, an exterior surface located on the delivery side of the fan impeller and an interior surface located on the intake side of the fan impeller. At least one raised element is mounted and/or configured on the exterior surface of at least one selection of the fan impeller blades, the element being positioned at a distance from the base plate and extending substantially in a diagonal manner away from the base plate from the front edge to the rear edge of the fan impeller blades.Type: GrantFiled: August 6, 2003Date of Patent: January 23, 2007Assignee: Rational AGInventors: Elmar Junker, Thomas Schreiner, Bruno Maas, Peter Kohlstrung, Manfred Breunig

Patent number: 7144437Abstract: A vertically oriented separator for separating liquid from a gas stream, where the incoming fluid enters the separator through an inlet nozzle arranged mainly perpendicular to the center axis of the separator and communicates with a circular swirl-inducing inlet device which is outwardly limited by the separator wall, inwardly limited by a mainly centrally arranged pipe and upwardly limited by a sealed top cover. The separator includes a first separation compartment arranged below the pipe and a second separator compartment arranged above the pipe, so the incoming fluid successively and under continuous swirl is forced to pass from the circular swirl-inducing inlet device to the first separator compartment and further through the pipe to the second separator compartment.Type: GrantFiled: October 18, 2002Date of Patent: December 5, 2006Inventors: Bjorn Christiansen, Knur Sveberg, Inge Hjelkrem, Dag Kvamsdal
