Abstract: A safety razor adapted to deliver a non-solid shaving aid material during normal use includes a handle, a razor cartridge and a reservoir for the shaving aid material in fluid communication with an applicator of the razor cartridge. When the non-solid shaving aid material includes liquid oil, the applicator has an outer layer of a hydrophobic non-woven material and an inner body of an oleophilic fibre pad.

Abstract: A handle for a safety razor is provided that includes an elongated hand gripping structure with a cartridge support structure at an end of the hand gripping structure. The hand gripping structure includes a frame and a first and second gripping pad. Each gripping pad can have a thermoplastic elastomeric gripping layer and a nonelastomeric thermoplastic support layer. The first gripping pad has an extension that cooperates with an opening of the frame to provide a snap fit joint between the frame and the first gripping pad. The second gripping pad has an extension that cooperates with the extension of the first gripping pad to prevent disengagement of the snap fit from the opening of the frame. The extension of the first gripping pad can be bifurcated and the extension of the second gripping pad can be received in the bifurcation.

Abstract: According to one aspect of the present invention, a lubrication box includes a first portion, a shaving aid material, and a second portion. The first portion of the lubrication box has a skin-engaging surface and at least one sidewall that, together, form a cavity. The skin-engaging surface includes at least two holes therethrough. The shaving aid material is pre-formed in a pre-determined shape, placed in the first portion of the lubrication box, and then compressed. The second portion of the lubrication box is attached to the first portion such that the cavity is substantially closed. A gap exists between in the cavity between the shaving aid and the second portion of the lubrication box to permit the shaving aid material to expand during normal use.

Abstract: The invention relates to primary electrochemical cells having a jellyroll electrode assembly that includes a lithium-based negative electrode, a positive electrode with a coating comprising iron disulfide deposited on a current collector and a polymeric separator. More particularly, the invention relates to a cell design which optimizes cell capacity and substantially eliminates premature voltage drop-off on intermittent service testing. The resulting cell has a region of increased lithium thickness proximate to/under the terminal end of the outermost edge of the cathode strip.

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 lighting device includes a touch switch with touch contacts 304, 306, located on the grip of the lighting device is that the light 312 can be turned on when the contacts are bridged by the hand of a user. An electronic circuit 300 includes a latching arrangement 302, 316 to latch the light on. The light can be dimmed by use of a further touch contact 308.

Abstract: Electrochemical cells including a casing or cup for direct electrical contact with a negative electrode or counter electrode and serving as the current collector for the electrode. The casing includes a substrate having a plated coating of an alloy including copper, tin and zinc, the coating having a composition gradient between the substrate and the external surface of the coating wherein the copper content is greater adjacent the substrate than at the external surface of the coating and the tin content is greater at the external surface of the coating than adjacent the substrate. Methods for forming a coated casing and an electrochemical cell including a coated casing are disclosed, preferably including providing an electrode casing with a coating utilizing variable current density plating that reduces discoloration of a surface exposed to the ambient atmosphere.

Abstract: A skin engaging member for a razor cartridge includes an erodible first layer and an erodible second layer below the first layer. Each layer includes a lubricious water soluble polymer and can include a water insoluble polymer. The second layer includes a fragrance that can be in the form of microcapsules or a suitable additive of the polymeric material(s). As the first layer erodes during normal use of the razor cartridge the second layer is eventually exposed dissolving or fracturing the microcapsules or otherwise releasing the fragrance. The fragrance is malodorous indicating to e.g. a vision impaired user that the optimal life of the razor cartridge is at or nearing its end. The first layer can also be provided with a non-malodorous fragrance. A third erodible layer can be provided between the first and second layer and can also include a fragrance. End-of-optimal-life indication can be rapid or gradual.

Abstract: A hydrogen generator and a fuel cell system including a fuel cell battery and the hydrogen generator. The hydrogen generator includes a cartridge including a plurality of pellets stacked within a casing, each pellet containing a hydrogen containing material capable of releasing hydrogen gas when heated; a compartment including a hydrogen outlet through a housing and as cavity within the housing within which the cartridge can be removably disposed; and an induction heating system. The induction heating system includes a plurality of secondary coils within the cartridge casing, with each secondary coil in contact with one or more of the pellets. The induction heating system also includes at least one primary coil within the compartment housing. The induction heating system provides an electromagnetic field from a flow of the current in the primary coil, induces an electric current in the secondary coil, and producing heat to heat the pellets.

Abstract: 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.

Abstract: The invention is a hydrogen generator including a pump for pumping a liquid from a reservoir to a reaction area, where the liquid reacts to produce hydrogen gas, and a fuel cell system including the hydrogen generator and a fuel cell stack. The pump is a diaphragm pump with mechanically operated liquid inlet and outlet valves that are opened by cam-operated pushrods, and the pushrods are isolated from the liquid flowpath through the pump by diaphragms. All valves in the liquid flow path between the liquid reservoir and the reaction area are mechanically operated valves.

Abstract: A razor cartridge has a housing having a guard and a cap and a plurality of parallel blades supported by the housing between the guard and the cap, each blade having a respective cutting edge. The guard includes a first and a second group of rows of elongated, elastomeric fins, each group being arranged generally parallel to the cutting edges and positioned to engage a user's skin, the second group being closer to the blades than the first group. The tips of the fins of the first group define a surface and an extension of the surface intersects the outer surface of the outermost fin of the second group to define a step between this intersection and a plane parallel to a plane through the cutting edges and tangential to the tip of outermost fin in a direction away from the guard.
