The dirt and fountain solution mixture in the dirt and fountain solution mixture container (24) is caused to settle in layers and the layer, containing the fountain solution, is transferred by an overflow (26) in to the fountain solution storage tank (20).Type: GrantFiled: April 28, 2005Date of Patent: November 6, 2007Assignees: Technotrans AG, Westfalia Separator GmbHInventors: Christian Walczyk, Christian Brüggemann, Jürgen Mackel

Publication number: 20070193959Abstract: A drip-filter extraction apparatus comprises a container, a flow rate controller and an extraction device. The container receives a liquid therein. The flow rate controller controls the liquid in the container flowing out at a constant flow rate. The extraction device collects the liquid and mixes it with extraction material to form a mixed liquid, and then the extraction device filters and collects the mixed liquid.Type: ApplicationFiled: February 20, 2007Publication date: August 23, 2007Inventor: Min Nin Yu

Patent number: 7235182Abstract: The invention provides a flotation device including a thickening tank (1) having right cylindrical sidewalls and a downwardly sloping frusto-conical floor. A drive shaft (2) is centrally rotatably mounted within the tank. Each one of a plurality of rake arms (3) is fixedly connected to the drive shaft and extends radially outwardly, substantially parallel to the tank floor. Each arm supports an array of blades (4) extending axially into the tank. An array of baffles in the form of rectilinear baffle plates (5), fixed relative to the tank, extends axially into the tank in complementary alternate radially spaced relationship with the blades (4). The baffle plates are located within the swept volume of the blades to retard fluid rotation in response to the rotation of the rake. A diametrical service bridge (6) is fixedly connected to the tank for mounting the baffle plates.Type: GrantFiled: March 11, 2003Date of Patent: June 26, 2007Assignee: OUTOTEC OYJInventors: David John Buchanan Taylor, Jeffrey Victor Belke

Patent number: 7217365Abstract: Methods wherein a blood cell concentration gradient is formed in a pooling unit in which blood is pooled before or after introducing the blood into a filter for eliminating leukocytes followed by the filtration are disclosed. By the first method comprising forming a blood cell concentration gradient in the pooling unit before introducing blood into the filter for eliminating leukocytes followed by the filtration, leukocytes can be efficiently eliminated from a whole blood preparation or a high platelet collection ratio can be established while maintaining a high leukocyte elimination ratio. By the second method comprising forming a blood cell concentration gradient in the pooling unit after introducing blood into the filter for eliminating leukocytes followed by the filtration, leukocytes can be efficiently eliminated from a whole blood preparation or a platelet preparation and platelets can be collected at a high ratio.Type: GrantFiled: April 26, 2002Date of Patent: May 15, 2007Assignee: Asahi Kasei Medical Co., Ltd.Inventors: Tatsuya Fukuda, Morikazu Miura

Patent number: 7153439Abstract: An oil/grease separator separates a lighter liquid from a mixture of the heavier liquid and a lighter liquid. A housing has an inner volume, an inlet to receive influent flow, an outlet to discharge the heavier liquid, which defines a static liquid level, and an outlet port above the static liquid level to discharge substantially all of the lighter liquid and portions of the heavier liquid. The lighter liquid floats on the heavier liquid, so that large volume flows into the inlet raises the liquid level in the housing, flowing the floating lighter liquid through the outlet port.Type: GrantFiled: November 10, 2004Date of Patent: December 26, 2006Assignee: Thermaco, Inc.Inventors: William C. Batten, Bruce Kyles, Charles Kemp

Patent number: RE40407Abstract: A method for entraining and mixing gas with liquids within a conduit or drop structure, comprising the channeling of one or more liquid flows into spiral flows of predetermined radius (radii), reducing the predetermined radius (radii) to increase the centrifugal forces acting upon the spiral flow(s) as the spiral flow(s) enter the conduit, and allowing gas access to the conduit to mix with and entrain within the spiral flow within the conduit or drop structure. The method can facilitate the mixing of gas with one or more fluid flows and/or reduce the release of gas emissions from the fluid(s) into the surrounding environment.Type: GrantFiled: October 14, 2005Date of Patent: July 1, 2008Assignee: Vortex Flow, Inc.Inventor: Eugene M.
