Patent number: 7494572Abstract: A mechanical water still (10) includes an impervious dome-like upper surface (12) and a membrane base (14) that is coupled (26) to the impervious dome-like structure (12) to form, when inflated, a chamber (20). The membrane base (14) supports a water pervaporation process therethrough. A water collection well (16) has an opening into which water droplets condensed from the water pervaporation process collect. The water collection well (16) is sited within the membrane base (14) and generally extends outwardly and downwardly from the membrane base (14), as shown in FIG. 1. In use, a contaminated water source (24) is brought into, ideally, complete contact with the membrane base (14), with the water collection well (16) arranged both to act as a heat sink into the water source (24) and to provide stability to the water still (10) when floating and immersed in the water source (24).Type: GrantFiled: June 10, 2003Date of Patent: February 24, 2009Assignee: Design Technology and Innovation Ltd.Inventors: Mark Christopher Tonkin, Mark Andrew Young, Neil David Eckert

Patent number: 6803107Abstract: Surface-treated superabsorbent polymer particles obtained by mixing 100 parts by weight of superabsorbent polymer particles with 0.001 to 10 parts by weight of a hydroxyalkylamide, and heating the surface-treated superabsorbent polymer particles to crosslink molecular chains existing at least in the vicinity of the surfaces of the superabsorbent polymer particles is disclosed. Surface crosslinking the superabsorbent polymer particles with a hydroxyalkylamide substantially increases both the rate of liquid absorption and the quantity of liquid absorbed and retained by the superabsorbent particles.Type: GrantFiled: May 16, 2003Date of Patent: October 12, 2004Assignee: BASF AktiengesellschaftInventors: Michael A. Mitchell, David Eckert, Thomas W. Beihoffer

Patent number: 6376618Abstract: Surface-crosslinked superabsorbent polymer particles are obtained by treating 100 parts by weight of superabsorbent polymer particles with about 0.001 to about 10 parts by weight of an oxazolinium ion. The oxazolinium ion can be formed in situ by heating superabsorbent particles treated with an oxazolinium ion precursor, such as a hydroxyalkylamide. A stable oxazolinium ion also can be used to surface crosslink the SAP particle. Surface crosslinking the superabsorbent polymer particles with an oxazolinium ion increases both the rate of liquid absorption and the quantity of liquid absorbed and retained by the superabsorbent particles.Type: GrantFiled: May 31, 2000Date of Patent: April 23, 2002Assignee: BASF AktiengesellschaftInventors: Michael A.

Patent number: 5763658Abstract: A process for decreasing the concentration of phenothiazine from a solution of acrylic acid by contacting the acrylic acid solution with a hydrophobic clay, such as an organophilic clay; or by protonating the phenothiazine, oxidizing the phenothiazine, and contacting the protonated, oxidized phenothiazine with a hydrophilic clay, such as an acid-activated smectite clay or sodium bentonite clay to sorb (absorb and/or adsorb) the phenothiazine into or onto the clay. Once sorbed onto the smectite clay, the phenothiazine easily can be removed, together with the clay, from the solution of acrylic acid, e.g., by filtration.Type: GrantFiled: October 18, 1995Date of Patent: June 9, 1998Assignee: AMCOL International CorporationInventors: Thomas W.
