Abstract: A sanitary napkin including a body-facing cover layer and an absorbent system adjacent the cover layer for receiving liquid therefrom, the napkin having enhanced fluid handing and masking properties.

Abstract: A hydrogen generator is provided for generating hydrogen gas for a fuel cell stack. The hydrogen generator includes a container, and a liquid reactant storage area configured to contain a liquid including a first reactant. The hydrogen generator also includes a reaction area within the container, and a solid containing a second reactant within the reaction area and having a concentration gradient that varies along an axis such as length of the solid. The hydrogen generator further includes a liquid delivery member for delivering the liquid to the solid in the reaction area to generate hydrogen. The concentration gradient controls a reaction rate of the first and second reactants.

Abstract: A battery charger (100) includes a base (102) which selectively receives first (104a) and second (104b) battery pods. The battery pods (104a, 104b), which are adapted to receive one or more batteries (212) for charging, have a form factor which facilitates the handling of the pods (104) and the batteries (212) received therein. Charging energy may be allocated between the pods (104) as a function of the temporal sequence in which the pods (104) are received by the base (102). Charging energy may also be allocated among the batteries (212) so that the batteries (212) are substantially charged at about the same time.

Abstract: A hydrogen generator is provided for generating hydrogen gas for a fuel cell stack. The hydrogen generator includes container, and a first reactant storage area configured to contain a liquid first reactant. The hydrogen generator also includes a reaction area and a solid second reactant within the reaction area, and a hydrogen outlet. The hydrogen generator further includes a flexible liquid delivery member extending into the reaction area and configured to deliver liquid reactant from the first reactant storage area to the reaction area. The flexible liquid delivery member includes a flexible portion that flexes to allow the delivery member to move with the solid second reactant as the second reactant is consumed.

Abstract: A lithium/iron disulfide electrochemical battery cell with a high discharge capacity. The cell has a lithium negative electrode, an iron disulfide positive electrode and a nonaqueous electrolyte. The positive electrode mixture containing the iron disulfide contains highly packed solid materials, with little space around the solid particles, to provide a high concentration of iron disulfide within the mixture. The separator is thin, to allow more space within the cell for active materials, yet strong enough to prevent short circuits between the positive and negative electrodes under abusive conditions, even when swelling of the cathode during cell discharge places additional stressed on the separator. As a result, the ratio of the interfacial capacity of the positive electrode to the electrode interfacial volume is high, as is the actual capacity on low rate/low power and high rate/high power discharge.

Abstract: A replacement cartridge for a safety razor includes a dispensing head and a reservoir for a flowable shaving aid material. A removable shield is between the reservoir and the dispensing head and the shield interrupts fluid communication between channels of the reservoir and the dispensing head when the shield is in place. Fluid communication is permitted when the shield is removed. Removal of the shield is a onetime event. The shield can be a thermoplastic film. A razor cartridge can be disposed adjacent the dispensing head and the housing of the razor cartridge can be integrally formed with the housing of the dispensing head.

Abstract: A valve assembly is provided with concentric fluid paths and may be used on a hydrogen generator to transport liquid reactant to the hydrogen generator and hydrogen gas. The valve assembly includes a housing defining first and second fluid paths, a first valve member disposed in the first fluid path, and a second valve member disposed in the second fluid path. The assembly includes a connector including a first elongated member configured to engage the first valve member to open the first valve member to allow a first fluid to flow through the first fluid path, and a second fluid port including a second elongated member configured to allow fluid to flow through the second fluid path. The valve assembly is concentric in that the second fluid path surrounds at least a portion of the first fluid path.

Abstract: The invention relates to electrochemical cells having a jellyroll electrode assembly that includes a lithium-based negative electrode, a positive electrode with a coating comprising greater than about 94 wt. % of iron disulfide.

Abstract: A hydrogen generator is provided for generating hydrogen gas for a fuel cell stack. The hydrogen generator includes a reaction area and a reactant storage area for storing a reactant composition for reacting to generate hydrogen gas. The hydrogen generator also includes a high pH solution contained within a solution storage area. Hydrogen gas is discharged through an outlet that passes through a filter to supply gas to the fuel cell. A predetermined quantity of high pH solution is injected into the reaction area to stop the reaction when electrical power is no longer demanded.

Abstract: Waste disposal devices and methods are provided. The device includes a housing, a lid, a bucket frame, a pair of members, and a foot pedal. The foot pedal is operatively associated with the lid and the pair of members so that the lid is in the closed position and the pair of members is in the non-use position when the foot pedal is in the upper position. Further, the foot pedal is operatively associated with the lid and the pair of members so that the lid is in the open position and the pair of members is in the use position when the foot pedal is in the lower position.
