Publication number: 20020088503Abstract: A system and method that removes an unwanted gas or unwanted gases or volatile liquids from containers or spaces that have only one venthole. The unwanted gases are replaced by a desirable, usually inert gas. The containers may be filled with granular solids of any size or shape; the containers may be of any size or geometry. The method consists of a pump system that applies small pressure oscillations to the single vent hole. These oscillations compress and expand the gas in the container. The resulting gas displacements in the container generate vortices in the gas spaces between the granular solids which mix the gases, replacing the unwanted resident gas by a desirable gas. The theory is related to the dispersion in porous media. Experiments are presented that document the time needed for the washout of the unwanted resident gas.Type: ApplicationFiled: January 5, 2001Publication date: July 11, 2002Inventor: Marc J. Jaeger

Patent number: 6095207Abstract: In a sealing device for a filling opening, especially for sealing it against the escape of fuel fumes when filling stationary or mobile supply tanks, a seal is located in the vicinity of the filling opening and abuts in a sealing fashion an object such as a filling device that is inserted into the filling opening. The seal automatically controlled by means of a control unit between an inactive resting position and an active sealing position of the seal. As a result, the seal is protected especially well against damage during insertion or withdrawal of the filling device, and reliable sealing can be expected in the long term.Type: GrantFiled: July 1, 1998Date of Patent: August 1, 2000Assignee: Mannesmans VDO AGInventor: Walter Enders

Patent number: 6076565Abstract: An adhesive fastener for securement to a substrate which has a reservoir comprising a reservoir cup and a piston located therein blocking entry of atmospheric water vapor and preventing unintentional leakage of adhesive from the reservoir and a wall portion of the reservoir may be displaced to prevent hydraulic lock as the piston is pushed into the reservoir during assembly of the fastener and also when the fastener is being deployed against the substrate. Apparatus and a method of filling the reservoir cups and inserting pistons therein while excluding atmospheric water vapor is disclosed.Type: GrantFiled: July 28, 1998Date of Patent: June 20, 2000Assignee: Theodore Sweeney & CompanyInventors: Engelbert A. Meyer, Drew J. Smith, Theodore J. Sweeney, Jr.

Patent number: 6068720Abstract: A method of manufacturing insulating glass units is disclosed that comprises delivering a succession of high temperature insulating glass units from an oven and a press, moving successive IGUs along a travel path with the major surfaces of each IGU extending substantially parallel to the major surfaces of adjacent IGUs, establishing an IGU cooling station on the travel path, moving the IGUs into heat exchange relationship with a fluent cooling medium at the cooling station to reduce the IGU temperature, and thereafter closing and sealing a vent opening of each IGU. Successive IGUs are moved along the travel path with their major surfaces disposed in substantially vertical planes and successive IGUs disposed in closely spaced relation. The cooling station comprises at least a blower for directing cooling medium onto IGUs moving through the cooling station. The blower directs cooling medium onto the IGUs in a direction parallel to the major surfaces.Type: GrantFiled: July 1, 1998Date of Patent: May 30, 2000Assignee: Edge Seal Technologies, Inc.Inventor: Michael P. McHugh

Patent number: 6050307Abstract: A method and apparatus for removing a heavier liquid from a container having a cover and containing a plurality of liquids of differing specific gravities. A sealable access is provided in the cover and a conduit having an end positioned within the liquid to be removed is connected at an opposite end to the sealable access. A superatmospheric medium is introduced into the container through the sealable access to create a pressure on a lighter liquid which acts as a plunger to pressurize the heavier liquid and force it through the conduit to be ejected to an exterior location via the sealable access.Type: GrantFiled: August 26, 1998Date of Patent: April 18, 2000Inventor: Armand R. Conti

Patent number: 6047747Abstract: Systems are provided for vehicular, land-based distribution of pressurized liquefied natural gas at a pressure of about 1035 kPa (150 psia) to about 7590 kPa (1100 psia) and at a temperature of about -123.degree. C. (-190.degree. F.) to about -62.degree. C. (-80.degree. F.). The systems include at least one container that is constructed from an ultra-high strength, low alloy steel containing less than 9 wt % nickel and having a tensile strength greater than 830 MPa (120 ksi) and a DBTT lower than about -73.degree. C. (-100.degree. F.).Type: GrantFiled: June 18, 1998Date of Patent: April 11, 2000Assignee: ExxonMobil Upstream Research CompanyInventors: Ronald R. Bowen, Moses Minta

Patent number: 6047743Abstract: An apparatus for providing oxygen-enriched air at a first pressure and at a second pressure, the second pressure being greater than the first pressure. The apparatus comprises, in combination, a pressure swing adsorption system and a pressure intensifier. The pressure swing adsorption system for enriching the oxygen content of air has a pressure of at least the first pressure. The pressure swing adsorption system is adapted to provide oxygen-enriched air to a first outlet at the first pressure and to provide oxygen-enriched air to a pressure intensifier at the first pressure. The pressure intensifier pressurises the oxygen-enriched air and provides the oxygen-enriched air to a second outlet at the second pressure.Type: GrantFiled: May 26, 1998Date of Patent: April 11, 2000Assignee: Litton Systems, Inc.Inventor: Gary Neal Byrd

Patent number: 6044647Abstract: A cryogenic liquid transfer system, for servicing a use device, releases stored cryogen from a bulk storage tank to a gas supply tank and a dispenser tank. The liquid cryogen in the gas supply tank is circulated through a circuit that includes a heat exchanger and the gas thus generated is returned to the gas supply tank so as to pressurize it. The pressurized liquid cryogen is released from the gas supply tank so that it flows through a vaporizer. The gas produced by the vaporizer is bubbled through the liquid cryogen in the dispenser tank so as to raise its temperature and pressure to the level required by the use device being serviced. Gas from the vaporizer is then delivered to the space above the liquid cryogen in the dispenser tank to as to create a pressure head that will cause the liquid cryogen to flow to the use device upon release. A venturi is connected to the tubing between the gas supply tank and the dispenser tank and is used to reduce the pressure in the bulk storage tank.Type: GrantFiled: August 5, 1997Date of Patent: April 4, 2000Assignee: MVE, Inc.Inventors: Thomas K. Drube, Paul A. Drube, A. Duane Preston
