Patent number: 6833340Abstract: A method of delivery of active substances to a water-filled environment, specifically a toilet bowl, with a water-soluble polymer as the primary delivery means. The present invention is activated by placement in the water, with the soluble polymer protecting the skin from exposure to the active ingredients. The soluble polymer is composed of a bi-layer capsule or tablet, preferably, with a solid, gas, gel, or liquid core. Alkali metal particles embedded in an interior layer of the capsule or tablet react with water once an exterior layer has dissolved. The alkali metal particles elevate water temperature, especially locally to the interior layer, and volatilize active substances contained within the interior layer. The active substances are preferably deodorants. Alternatively, capsule or tablet is covered with a non-water-soluble final coating layer so that if the present invention is stored or delivered in an aqueous solution, the active substances will not be delivered until desired.Type: GrantFiled: April 17, 2003Date of Patent: December 21, 2004Assignee: LB Developments, LLCInventors: Michael Lefenfeld, Steven Berman, Jared Berman, Murray Katz

Patent number: 5206094Abstract: A fuel cell stack is cooled by evaporation of water into a carrier gas such as fuel or oxidant. The coolant and the carrier gas are separately supplied to the cooler, and this allows the fuel cell to operate at high pressure without raising cell temperature.Type: GrantFiled: November 30, 1990Date of Patent: April 27, 1993Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: Murray Katz

Patent number: 5009968Abstract: The end plates (16) of a fuel cell stack (12) are formed of a thin membrane. Pressure plates (20) exert compressive load through insulation layers (22, 26) to the membrane. Electrical contact between the end plates (16) and electrodes (50, 58) is maintained without deleterious making and breaking of electrical contacts during thermal transients. The thin end plate (16) under compressive load will not distort with a temperature difference across its thickness. Pressure plate (20) experiences a low thermal transient because it is insulated from the cell. The impact on the end plate of any slight deflection created in the pressure plate by temperature difference is minimized by the resilient pressure pad, in the form of insulation, therebetween.Type: GrantFiled: September 8, 1989Date of Patent: April 23, 1991Assignee: International Fuel Cells CorporationInventors: Robin J. Guthrie, Murray Katz, Craig R. Schroll

Patent number: 4983472Abstract: A fuel cell has a current collector plate (22) located between an electrode (20) and a separate plate (25). The collector plate has a plurality of arches (26, 28) deformed from a single flat plate in a checkerboard pattern. The arches are of sufficient height (30) to provide sufficient reactant flow area. Each arch is formed with sufficient stiffness to accept compressive load and sufficient resiliently to distribute the load and maintain electrical contact.Type: GrantFiled: November 24, 1989Date of Patent: January 8, 1991Assignee: International Fuel Cells CorporationInventors: Murray Katz, Stanley P. Bonk, Donald L. Maricle, Martin Abrams

Patent number: 4761348Abstract: An electrolytic cell stack includes inactive electrolyte reservoirs at the upper and lower end portions thereof. The reservoirs are separated from the stack of the complete cells by impermeable, electrically conductive separators. Reservoirs at the negative end are initially low in electrolyte and the reservoirs at the positive end are high in electrolyte fill. During stack operation electrolyte migration from the positive to the negative end will be offset by the inactive reservoir capacity. In combination with the inactive reservoirs, a sealing member of high porosity and low electrolyte retention is employed to limit the electrolyte migration rate.Type: GrantFiled: March 17, 1987Date of Patent: August 2, 1988Assignee: The United States of America as represented by the United States Department of EnergyInventors: H. Russell Kunz, Robin J. Guthrie, Murray Katz

Patent number: 4596748Abstract: Electrolyte lost from a fuel cell, such as by evaporation, is replenished by introducing electrolyte from an external source into a reactant gas stream being delivered into the cell. The fresh electrolyte is vaporized or formed into droplets as it enters the cell such as by spraying the fresh electrolyte into the gas stream. If the electrolyte vapor pressure in the entering gas stream is made high enough, evaporation of the electrolyte from the cell can be halted or electrolyte can even be added to the cell from the gas stream.Type: GrantFiled: April 11, 1984Date of Patent: June 24, 1986Assignee: United Technologies CorporationInventors: Murray Katz, Harold R. Kunz

Patent number: 4548874Abstract: Electrical short protection is provided in an electrolytic cell stack by the combination of a thin, nonporous ceramic shield and a noble metal foil disposed on opposite sides of the sealing medium in a gas manifold gasket. The thin ceramic shield, such as alumina, is placed between the porous gasket and the cell stack face at the margins of the negative end plate to the most negative cells to impede ion current flow. The noble metal foil, for instance gold, is electrically coupled to the negative potential of the stack to collect positive ions at a harmless location away from the stack face. Consequently, corrosion products from the stack structure deposit on the foil rather than on the stack face to eliminate electrical shorting of cells at the negative end of the stack.Type: GrantFiled: November 29, 1984Date of Patent: October 22, 1985Assignee: The United States of America as represented by the United States Department of EnergyInventors: Murray Katz, Craig R. Schroll

Patent number: 4259302Abstract: Ammonia gas is scrubbed from a gas stream in a bed of material soaked with acid, and the bed is regenerated by passing an oxygen containing gas therethrough. The preferred acid is phosphoric acid and the preferred support material is carbon in the form of porous particles. In a fuel cell system dual scrubbers alternately scrub ammonia from reform gas and are subsequently regenerated so as to provide the fuel cells with a continuous flow of substantially ammonia free hydrogen.Type: GrantFiled: November 8, 1979Date of Patent: March 31, 1981Assignee: United Technologies CorporationInventors: Murray Katz, Gary A. Gruver, H. Russell Kunz

Patent number: 4078119Abstract: A porous conducting particle, hydrophobic bonded, substrate supported electrode is prewetted with the electrolyte. A D.C. voltage is applied to the electrode to assist in the prewetting with the electrolyte. A soluble catalyst-containing material is then introduced into the electrode structure and the catalyst deposited within the electrode. By appropriate selection of the porous conducting particles and the catalyst-applying techniques, precise control of the location of the catalyst can be obtained. If graphite materials are used as the conducting particles, a catalyst-containing salt is allowed to dissolve in the electrolyte in the prewetted electrode, and the catalyst-containing material is reduced to the metal. If the reduction is done by reaction with a reducing gas such as hydrogen, the catalyst will be deposited only in those regions of the electrode at which there is an electrolyte-reactant gas interface which is in electrical-conducting relationship with the substrate.Type: GrantFiled: May 17, 1976Date of Patent: March 7, 1978Assignee: United Technologies CorporationInventors: Murray Katz, Arthur Kaufman

Patent number: 3990912Abstract: In a fuel cell stack utilizing an alkali metal electrolyte, the electrolyte is distributed in parallel between the electrodes of a plurality of fuel cells and is then fed to regenerator cell which converts carbonate ions to molecular CO.sub.2 gas which is discharged from the cell. Regeneration is effected through the establishment of a hydroxyl ion gradient within a regenerator cell. The regenerated electrolyte is then returned to the fuel cells. In this manner a carbonate buildup in the cells is prevented.Type: GrantFiled: June 13, 1974Date of Patent: November 9, 1976Assignee: United Technologies CorporationInventor: Murray Katz
