Foam generation continues so as to push the foam up in the column, wherein much of the solvent that is in the foam is allowed to drain back down into the column. The foam passes through concentrators which increase the residency time of the foam in the column to further dry the foam and to create larger bubbles. The drier foam is pushed out of the column and into a container. The foam is broken up into gas and the liquid foaming contaminants. The gas is recirculated for injection into the column even after foaming has stopped. The foaming contaminants are concentrated at the surface level of the solvent in the column. These contaminants are removed from the column.Type: ApplicationFiled: May 22, 2003Publication date: November 6, 2003Inventor: Stephen A. von Phul

Publication number: 20030205535Abstract: The invention is directed to a method of purifying water and wastewater as a fluent coming from industrial plants, municipal sewage systems, reservoirs and other water supplies and residential community and commercial water and sewage supplies and systems. The method includes the steps of running the wastewater as a fluent into a headworks where some preliminary treatment takes place. From there the fluent is passed into a primary reservoir. The fluent in the primary reservoir is analyzed as to certain control parameters such as pH and conductivity. Thereafter the fluent flows into a primary reactor having a plurality of electrolytic cells therein. While in that reactor the fluent is subjected to electrolytic reactions. The effluent from the primary reactor passes through a ratio weir into a secondary receptor. The secondary receptor contains sensors for the measurement of control parameters such as pH, (total suspended solids) TSS and chlorine. Thereafter, the fluent is passed to a filtering device.Type: ApplicationFiled: May 3, 2002Publication date: November 6, 2003Inventor: William Jeffrey Roth

Publication number: 20030205537Abstract: A filter for a spa or pool, having a filter body which receives a filter bag having a sheath encompassing the exterior of the filter body and a pocket extending inwardly from the front end of the sheath into the filter. Operation of the spa water circulation system draws spa water into the filter bag pocket while concurrently spa water is drawn transversely through the filter bag sheath and auxiliary spa water openings into the filter body. An O-ring encircles the upper portion of the filter bag to releasably retain such bag to the filter body during operation of the spa water circulation system.Type: ApplicationFiled: May 30, 2003Publication date: November 6, 2003Inventor: Gregg W. Leaverton

Publication number: 20030205538Abstract: A platelet collection device comprising a centrifugal spin-separator container with a cavity having a longitudinal inner surface. A float in the cavity has a base, a platelet collection surface above the base, an outer surface. The float density is below the density of erythrocytes and above the density of plasma. The platelet collection surface has a position on the float which places it below the level of platelets when the float is suspended in separated blood. During centrifugation, a layer of platelets or buffy coat collects closely adjacent the platelet collection surface. Platelets are then removed from the platelet collection surface. Movement of a float having a density greater than whole blood through the sedimenting erythrocytes releases entrapped platelets, increasing the platelet yield.Type: ApplicationFiled: June 18, 2002Publication date: November 6, 2003Inventors: Randel Dorian, Scott R. King, Richard W. Storrs
