One of the sub-chambers (26) of the vacuum container (10) houses a heating device (28, 30), which heats the fluid mixture. The fluid mixture is guided into an additional sub-chamber (40), and is separated into its constituents by traversing a packed bed. Even cold and consequently viscous fluid mixtures can be supplied, due to the heating device, for separation inside the aforementioned vacuum container.Type: GrantFiled: May 24, 2002Date of Patent: April 3, 2007Assignee: Hydac Filtertechnik GmbHInventors: Knut Herges, Andreas Busch

Patent number: 6264830Abstract: A water treatment method uses a removable, disposable cartridge having an internal mesh structure. A disposable heater heats water fed to the cartridge. Precipitated solids collect on the mesh surface provided temperature and residence time are appropriately maintained. The heat breaks down the bicarbonate hardness of the water thereby depositing carbonates on the mesh surface and heavy metals will be codeposited due to the resultant change in pH. The cartridge has a head-space for collecting entrained gases such as volatile organic compounds, chlorine and air. Water sterility is achieved by heating the water over an appropriate period of time. Turbidity is removed within the cartridge due to settling induced by the low fluid velocity controlled by a controller and by a filter provided at the outlet of the cartridge. The filter will become blocked when bicarbonate hardness is carried over forcing a user to replace a spent cartridge.Type: GrantFiled: August 13, 1999Date of Patent: July 24, 2001Assignee: The Coca-Cola CompanyInventors: George Plester, Willy Van Esch

Patent number: 6206090Abstract: The invention relates to a combined heat exchanger and fluid filter that can be used in a gas turbine engine for example to simultaneously filter lubricating oil and fuel while transferring thermal energy between the oil and fuel. Conventionally, fuel and oil filters as well as a heat exchanger are separately mounted in an engine with a multitude of pipes conducting fluids between them. The invention packages these components together and achieves several benefits as a results, including: reduction in number of parts, cost of manufacture and installation; containment of the risk of damage or leakage; ease of access for assembly, inspection and maintenance; and simple application to a number of different engines by merely extending the length of the filters/exchanger on a standard manifold design.Type: GrantFiled: May 20, 1999Date of Patent: March 27, 2001Assignee: Pratt & Whitney Canada Corp.Inventor: Giusseppe Rago

Patent number: 6139725Abstract: An oil reclamation device includes a full flow filter (10) fitted around a partial flow filter (12) within an open-ended casing (8). The open end of the casing is capped by a housing defining a vaporization chamber (6). In normal operation, oil flows from oil passage (14) through the full flow filter (10) to a branched leg (22). A metering jet (34) provided in the branched leg allows a minor portion of the oil to flow through the partial flow filter and then into the vaporization chamber. The full flow filter extracts solid contaminants having a particle size of 15 microns or greater. The partial flow filter extracts solid contaminants of 1 micron or greater. The filter element of the partial flow filter is composed of compressed cotton fibers and preferably has a higher density in an upper end adjacent the vaporization chamber. In the vaporization chamber, liquid contaminants are removed from the minor portion by a heating element (72).Type: GrantFiled: September 22, 1998Date of Patent: October 31, 2000Assignee: Purdayn Filter Technologies IncInventors: Richard Henry Howard Barr, Albert Neal Davies

Patent number: 5198104Abstract: A device that reclaims industrial fluids. Solid contaminants are removed from the liquid being reclaimed by a series of increasingly fine filter elements positioned within a filter housing. The substantially solid contaminant-free fluid then enters an evaporation chamber having a design that constrains the fluid to form a thin film atop an evaporation plate at the bottom of the chamber to facilitate evaporation of volatile contaminants. Insert members are positioned within the evaporation chamber to increase the surface area of the thin film to further enhance the removal of the volatile contaminants. The temperature and pressure of the evaporation chamber is controlled by a heating element that is under the control of a temperature sensor. Evaporated volatile contaminants escape the evaporation chamber through a port formed in the head that closes the device. Latches are used to secure the head in the absence of conventional nuts and bolts, and the head screw threadedly engages the evaporation plate.Type: GrantFiled: March 12, 1991Date of Patent: March 30, 1993Assignee: Lubrication Technologies, Inc.Inventor: W.

Patent number: 4793938Abstract: A system is provided for purging contaminants from dry cleaning fluid used in a machine for dry cleaning clothing while concurrently decontaminating the filter cartridges through which the dry cleaning fluid is passed. The system is coupled in a recirculating loop to and from a machine for dry cleaning clothing. A plurality of filter cartridge housings are employed so that one filter cartridge housing can be selected and isolated from the dry cleaning machine, while the other filter housings remain in the recirculation loop. A portion of the dry cleaning fluid in the selected housing is vaporized within the filter housing while another portion is forced in liquid form through the filter cartridges in a direction opposite to the flow in the recirculation loop. This liquid portion is passed to a separate boiler for vaporization. The vaporized dry cleaning fluid from both the filter housing and the boiler is condensed and passed to a gravity separator, where water is separated from the dry cleaning fluid.Type: GrantFiled: November 18, 1986Date of Patent: December 27, 1988Inventor: James E.
