| 20090075050 | Addition of continuous elements to non-woven mat - A reinforced chopped strand mat formed of a plurality of chopped reinforcement fibers and at least one continuous element positioned in a substantially parallel orientation in the machine direction is provided. In the reinforced chopped strand mat, the fibers are dispersed in a randomly oriented configuration at least partially surrounding the continuous elements. In preferred embodiments, the continuous element is either a wet continuous glass strand or a dry continuous yarn. The continuous elements are positioned within the chopped strand mat in a parallel or substantially parallel orientation and may be substantially equidistant from each other or irregularly spaced. Desirably, the continuous elements are equidistantly spaced about 0.25 inches to about 3 inches apart. The continuous elements simultaneously improve tensile strength and tear strength of the reinforced chopped strand mat. Methods of forming the reinforced chopped strand mat are also provided. | 03-19-2009 |
| 20090159228 | Variable dispersion of wet use chopped strand glass fibers in a chopped title strand mat - A size composition for reinforcement fibers used to form non-woven mats that contain variable amounts of individual filaments dispersed from chopped reinforcement fiber bundles is provided. The size composition contains a polyvinylamine film former, one or more silane coupling agents, and, optionally a lubricant. The size composition works in conjunction with the whitewater components in a wet-laid mat forming process to disperse individual filaments from the bundles of chopped fibers. The whitewater contains an anionic polyacrylamide viscosity modifier and/or a cationic or non-ionic amine dispersant (e.g., ethoxylated amine). The presence of a cationic or non-ionic amine in the whitewater disperses individual filaments from the chopped glass fiber bundles. The greater the amount of cationic or non-ionic amine present in the whitewater, the greater the amount of fiber dispersion. The absence of a cationic or non-ionic amine and the presence of an anionic polyacrylamide viscosity modifier maintain full bundle formation integrity. | 06-25-2009 |
| 20090209681 | UREA-FORMALDEHYDE RESIN REINFORCED GYPSUM COMPOSITES AND BUILDING MATERIALS MADE THEREFROM - A composite material containing substantially homogeneous matrix of a gypsum material and a urea-formaldehyde material where wet-used chopped strand fibers are filamentized within the substantially homogeneous matrix. | 08-20-2009 |
| 20110056157 | UREA-FORMALDEHYDE RESIN REINFORCED GYPSUM COMPOSITES AND BUILDING MATERIALS MADE THEREFROM - A composite material containing substantially homogeneous matrix of a gypsum material and a urea-formaldehyde material where wet-used chopped strand fibers are filamentized within the substantially homogeneous matrix. | 03-10-2011 |
| 20110190434 | UREA-FORMALDEHYDE RESIN REINFORCED GYPSUM COMPOSITES AND BUILDING MATERIALS MADE THEREFROM - A composite material containing wet chopped strand fibers, gypsum, and a polymer material is provided. The wet fibers are filamentized within the polymer material. In exemplary embodiments, the wet chopped strand fibers are wet-used chopped strand glass fibers. The gypsum may be α-gypsum, β-gypsum, or combinations thereof. In at least one embodiment, the polymer is a urea-formaldehyde resin. The composite material may contain a facing layer on at least one exposed major surface of the composite material. A method of forming a composite material that includes mixing gypsum with a polymer material to form a substantially homogeneous matrix and adding a sufficient quantity of wet-used chopped strand fibers to form the composite material is also provided. | 08-04-2011 |

| 20130108940 | Hydrogen Generator | 05-02-2013 |
| 20140044605 | Fuel Unit, Refillable Hydrogen Generator And Fuel Cell System - A packaged fuel unit and a refillable hydrogen generator that uses the fuel unit to produce hydrogen gas are disclosed. The fuel unit includes a reactant that can undergo a thermal decomposition reaction that produces hydrogen gas when heated to at least a minimum initiation temperature. The reactant is contained within a package that includes a poor thermal conductor with one or more thermal conductor sections for conducting heat from outside the package to the reactant. The hydrogen generator includes a holder with a cavity in which the fuel unit can be removably disposed and a heating system for heating the fuel unit when disposed therein. The hydrogen generator can be part of a fuel cell system including a fuel cell battery that is provided with hydrogen gas from the hydrogen generator. | 02-13-2014 |
| 20140137562 | Hydrogen Generator Having a Thermal Actuator - A hydrogen generator having one or more actuators coupled to one or more heating elements in which the actuator(s) are used to improve the transfer of thermal energy from heating element(s) to one or more fuel units contained within the generator. In one embodiment, an actuator allows insertion and/or removal of packaged fuel units without the need of removing the heating element(s) and/or the actuator(s). When the actuator is in a retracted state (e.g., a low temperature state), the packaged fuel unit may be inserted and/or removed from a cavity of the hydrogen generator. When the actuator is in an extended state (e.g., a higher temperature state), the actuator forces contact between itself or the heating element and the fuel unit when a prescribed operating temperature is reached. | 05-22-2014 |
| 20140295304 | METHODS OF GENERATING HYDROGEN GAS AND POWER - A hydrogen generator and a fuel cell system including a fuel cell battery and the hydrogen generator. The hydrogen generator includes a cartridge, a housing with a cavity to removably contain the cartridge, and an initiation system. The cartridge includes a casing; a plurality of pellets including a hydrogen containing material; a plurality of solid heat transfer members in contact with but not penetrating the casing; a hydrogen outlet in the casing; and a hydrogen flow path from each pellet to the hydrogen outlet. A plurality of heating elements is disposed inside the housing. When the cartridge is in the cavity, each heating element is disposed so heat can be conducted from the heating element and through the casing and corresponding heat transfer member to initiate the release of hydrogen gas. The initiation system can selectively heat one or more pellets to release hydrogen gas as needed. | 10-02-2014 |

The hydrogen generator includes a reactant that undergoes a thermal decomposition reaction to produce hydrogen when heated. A laser is used to initiate the reaction. The reactant is contained in a reactant composition in a user-replaceable disc-shaped fuel unit. The reactant composition can be segregated into individual quantities. The fuel unit and the laser beam are periodically realigned by incrementally rotating the fuel unit and/or incrementally redirect the laser beam. | 03-12-2015 |
