International Classification:

C08G 1828

US Classification:

521172, 521110, 521112, 521130, 525123, 525127, 525453

Abstract:

An ester polyurethane foam is prepared by reacting a mixture of one or more polyester polyols with one or more isocyanates and one or more silicone surfactants in the presence of a blowing agent, such as water, and other additives, such as catalysts. The cured foam is chemically treated in a caustic solution to form a hydrophilic ester polyurethane foam having a water absorption rate of at least 20 pounds of water per square foot per minute, preferably at least 25 pounds of water per square foot per minute. The foam also has greater water holding capacity and wet strength than cellulose.

International Classification:

H01M 2/00

US Classification:

429 34, 429 12, 429 35

Abstract:

The present invention concerns a fuel reservoir for a liquid fuel cell particularly useful for portable electronic devices in which the fuel reservoir can deliver the liquid fuel regardless of the orientation. The fuel reservoir comprises (a) a container defining a cavity for holding the liquid fuel; (b) a wicking structure positioned within the cavity and into which at least a portion of the liquid fuel wicks and from which said liquid fuel subsequently may be discharged or delivered, such as by pumping or wicking. The wicking structure is formed from a wicking material with a free rise wick height greater than at least one half of the longest dimension of the wicking structure. Among materials with such wicking capability are foams, matted, bundled or woven fibers and nonwoven fibers. The container may have a generally flat and thin profile, formed as a pouch or envelope with substantially planar top and bottom faces of flexible film material, such that the container holding the wicking structure and filled with the liquid fuel can be bent or shaped.

US Classification:

Abstract:

Water recovery in direct liquid fuel cells, particularly direct methanol fuel cells, is accomplished by incorporating a capillarity structure composed of a capillarity material, which may be a composite material, adjacent to the cathode. The capillarity material has a free rise wick height of at least one half its longest dimension. The capillarity materials may be selected from foams, matted fibers, bundled fibers, woven fibers and nonwoven fibers. In one embodiment, holes or perforations are formed through the thickness of the sheet, and a conductive layer is adjacent to, adhered to or coated on at least one surface of the capillarity material. To recycle water, a second capillarity structure of capillarity material is incorporated adjacent to the anode, and a liquid flow path is provided between the first and second capillarity structures. The absorbed water flows through the liquid flow path, is mixed with fuel and introduced to the second capillarity structure adjacent to the anode.

International Classification:

B65D001/00

US Classification:

428034100

Abstract:

A reticulated polyurethane foam having a density less than 1.0 pounds per cubic foot [16 kg/m] forms an explosion suppressing material that is installed into the inner volume of a fuel tank to fill from 50 to 90% or up to 100% of the volume of such tank. The reticulated polyurethane foam has particular advantage when used in a fuel tank for an aircraft.

International Classification:

C08J 906
C08G 1810
C08G 1848

US Classification:

521159

Abstract:

Isocyanate-terminated-prepolymers prepared from polyoxyalkylene polyether polyols having low unsaturation are suitable for producing polyurethane molded foam having exceptional physical properties. Preferably, the foams are all water blown, and process well. The foams are noted for concomitant increases in both tensile strength and elongation as well as displaying excellent wet set and other properties.

Arco Chemical Technology, L.P. - Greenville DE

International Classification:

C08G 810

US Classification:

521174

Abstract:

Very soft, very low density, all water-blown polyurethane foams are prepared by reacting an isocyanate-terminated prepolymer with from 30% to 150% stoichiometric excess of water. The foams have molded densities less than or equal to 1. 5 lb/ft. sup. 3 and softness, as measured by 25% ILD of less than or equal to 15 lbs. , yet retain excellent resiliency, tear strength and elongation. The foams are suitable for use in cushioning applications such as those traditionally employing polyester fiberfill.
