A motive flow of a liquid packing vehicle such as a non-polar organic solvent is established along a feed conduit by a pump (111). The medium, for example silica which is poorly compatible with low-polarity vehicles, is easily entrained in the motive flow by introducing it into the feed conduit (16, 18) via an ejector (30). This avoids subjecting the medium to the action of a mechanical pump.Type: GrantFiled: December 6, 2000Date of Patent: September 10, 2002Assignee: Euroflow (UK) LimitedInventors: Martin J. Hofmann, Gordon R. Thorn

Publication number: 20020121312Abstract: A lifting mechanism includes a plurality of lift pins which may be driven separately and independently upward to engage an alignment surface of the chamber using ambient atmospheric pressure as the chamber is evacuated by a pump. In the illustrated embodiment, each lift pin includes a piston which is exposed to the internal chamber pressure on one side of the piston, and is exposed to the external ambient pressure on the other side of the piston. As the pump evacuates the chamber, the internal chamber pressure decreases, causing each lift pin piston to drive the associated lift pin upward. Once all the lift pins have securely engaged the alignment surface, the lift pins may be clamped to a linking mechanism to permit a motor to actuate the lift pins during processing operations.Type: ApplicationFiled: March 1, 2001Publication date: September 5, 2002Inventors: Dmitry Lubomirsky, Sheshraj Tulshibagwale, Donald Olgado, Avi Tepman

Patent number: 6427729Abstract: A method and system of pressurizing natural gas, and/or other gaseous substances, indirectly, by pressurizing a liquid-filled chamber in which a flexible bladder has been inserted which holds the gas to be pressurized. This Indirect Pressurization Facility (IPF) will take small volumes of gas, at pressures less than the pressure inside a gas sales line, boost the pressure by pumping a liquid onto the outside of the bladder which collapses the bladder and re-positions the trapped gas into a smaller confinement which results in an increase in the pressure of the gas. When the increased pressure reaches a level above the sales line pressure, the gas will be squeezed out and into the sales line. The process is then repeated until the gas supply from the well declines to a point where it is no longer economically-justified to continue operations.Type: GrantFiled: May 30, 2001Date of Patent: August 6, 2002Inventor: James Rose Teel

Patent number: 6427730Abstract: A vent and fluid transfer fitment for sealing and transferring a fluid from an inverted fluid-filled container without premature leakage to a receiver attachment, has a transfer check valve and a venting check valve which are preferably duckbill valves. The transfer check valve is attached to the fitment for allowing fluid to be transferred from the container when the receiver attachment engages the transfer check valve. The venting check valve is also attached to the fitment for allowing air to displace the fluid as the fluid exits the container, wherein both the transfer check valve and the venting check valve have an inherent sealing pressure created by the static pressure of the fluid within the container. In addition, the inherent sealing pressure of the venting check valve is less than the inherent sealing pressure of the transfer check valve which allows air to enter the container due to the pressure differential created as the fluid is displaced.Type: GrantFiled: December 18, 2000Date of Patent: August 6, 2002Assignee: The Procter & Gamble CompanyInventors: Phillip Gene Nagel, James Christopher Bailey, Gordon Edgar Atkinson, Arnold George Benecke

Patent number: 6418982Abstract: A process of bulk filling containers which includes the steps of arranging a number of containers upside down in a tray (24) that has a raised peripheral lip (26). This tray full of containers is then placed in a vacuum chamber (28) which is then evacuated to a predetermined level below atmospheric pressure. Liquid (36) is then introduced into the tray through a reservoir (38) and conduit (40) which penetrates the wall of the vacuum chamber and the vacuum within the chamber is gradually released at a rate that draws the liquid into the containers. At this point in the process unwanted liquid is rinsed away and the tray is removed from the chamber and turned right side up. The final step is to seal the top of the containers with an appropriate cap, barrier, tip or connection. A second embodiment adds a step to the process by positioning the containers upside down in a rack (74) and positioning the rack directly above the tray containing the liquid.Type: GrantFiled: November 21, 2000Date of Patent: July 16, 2002Assignee: Amphastar Pharmaceuticals Inc.Inventors: Jack Y.
