Abstract: Methods and systems for making an absorbent pad for use in an absorbent article utilize a forming device for forming material into an absorbent core, a supply device for supplying a containment layer against the first surface of the absorbent core and spray apparatus for spraying fibers of molten resin onto the second surface of the absorbent core. The fibers form a stabilization layer on the absorbent core that increases the integrity of the absorbent core. The spray apparatus includes a nozzle having a resin aperture for exhausting resin therefrom and multiple gas apertures for exhausting gas therefrom to provide a random pattern to the fibers of molten resin as the fibers are sprayed onto the second surface. Resin can also be sprayed onto first and second portions of the containment layer extending outwardly from edges of the absorbent core so the containment layer and the stabilization layer encompass the absorbent core.

Abstract: This invention pertains to a fish pond system for use as a fish pond amusement park. The fish pond system includes a fish pond having at least one fish container in a deeper, typically a central region, and a pond liner extending outwardly from the fish container, preferably inclined at a generally upward angle, preferably less than 10 degrees. The pond has a shallower zone having a depth of at least about 7 inches at the juncture of the central region and the shallower zone. The fish container has greater depth than the shallower zone such that fish congregate in the fish container. The fish pond system preferably includes a water recirculation system receiving water from the bottom of the fish container, passing the water through a settling container, typically a settling pond, and returning the water to the fish pond. Fish waste solids settle to the bottom of the settling pond, and are removed to a decomposition pond within the fish pond system, where the fish wastes are biologically decomposed by plants.

Abstract: An absorbent article includes an absorbent pad and an outer cover. A release agent is applied to one of the outer surface of the absorbent pad and the inner surface of the outer cover. The release agent prevents at least a portion of the outer cover from adhering to the absorbent pad. In embodiments where the outer cover is extensible in a cross-direction and/or a longitudinal direction, the release agent prevents the absorbent pad from resisting mobility of the outer cover. Thus the absorbent pad has substantially no adhesion to the outer cover where the release agent is applied. Therefore, tearing of the absorbent pad and damage to, or release, of superabsorbent material from the absorbent pad during extension of the outer cover, is prevented. The release agent can be a silicon-active agent or a powder material having properties that prevent adhesion between adhesive and a forming tissue of the absorbent pad, or the outer cover.

Abstract: This invention relates to absorbent pads, and methods for fabricating absorbent pads, having improved fluid intake and preferential wicking in the longitudinal direction. The absorbent pads have patterns of apertures which encourage the preferential wicking. The apertures are characterized by size, spacing from each other, and depth of penetration into the absorbent pad, such that fluid intake rate is increased and distribution of fluid in the longitudinal direction is improved. Apertures are preferably spaced close enough to each other that aqueous liquid is preferentially transferred from aperture to aperture by capillary effect, along the length of the absorbent pad. Preferential wicking between apertures in the longitudinal direction increases the overall effective liquid absorption rate of the absorbent pad, thereby increasing overall effective liquid capacity of the respective absorbent article.

Abstract: This invention pertains to metal-air electrochemical cells wherein one or more air entry ports is located in the bottom of the cathode can, to provide for entry of oxygen-rich air into the cathode can, where the oxygen participates in the chemical reaction whereby the cell produces electrical energy. In this invention, multiple small air entry ports are provided. Generally, the use of multiple ports distributed over the bottom of the cathode can, opposite the reaction surface of the cathode assembly, while not increasing the overall open area of the ports, results in an increase in the ratio of the cell limiting current to the rate at which moisture is lost from the cell. Accordingly, moisture loss as a function of electrical energy produced, is reduced.

The invention provides improved structure, and methods for making the outer edge of the closed end of the can at the joinder of the closed end of the can with an side wall extending from the closed end. A substantially flat portion of the outer surface of the closed end of the can extends outwardly of the inner surface of the side wall. The electrochemical cells are assembled using improved assembly methods. Button-type electrochemical cells made using the invention are free of the inward dishing common to especially cathode cans in such button cells.

Abstract: An absorbent article includes an absorbent core positioned between a bodyside liner and an outer cover. Containment flaps are inwardly folded to form containment reservoirs which inhibit exudates from leaking through or out of the absorbent article. The containment flaps include flap elastics which form surface contact with the user's body. The containment flaps are generally spaced outwardly from the absorbent core to increase the capacity of the reservoirs. In one embodiment, the unfolded containment flaps have a width greater than the crotch side width from the absorbent core to an outer edge of the absorbent article. This arrangement also allows the absorbent article to contain a sudden increase in exudates.

Abstract: This invention pertains to novel electrochemical metal air cells having improved closed circuit voltage characteristics. The improved voltage characteristics are illustrated at a constant load of 51 ohms. The closed circuit voltage during an initial placement into use of the cell of the invention has a decreased voltage drop relative to prior art cells, and recovers to a higher voltage. For example, the closed circuit voltage of the metal air cell drops to a minimum voltage during the first 20 seconds of initial placement into use. The minimum voltage is no more than 22% less than the initial open circuit voltage. This voltage drop is less than the voltage drop of other known metal air cells at 51 ohms. Metal air cells of the invention recover, during the first minute of use, to a closed circuit voltage of at least 79% of the initial open circuit voltage. The value of the open circuit voltage of the metal air cell of the invention is preferably about 1.43 volt.

Abstract: The invention relates to methods of applying adhesive to a lateral edge of a first web. The method includes transporting the first web along a first path and transporting a second web along a second path generally in surface-to-surface relationship with the first web at the lateral edge, with the second web extending outwardly from the first web. When adhesive is applied such as by spraying to the first web at the lateral edge, at least some adhesive passes outwardly of the lateral edge as overspray and is received by the second web. Thus, adhesive applied to the edge of the first web is received in combination by both of the first and second webs. Both of the first and second webs can be utilized in manufacturing articles. In some embodiments, adhesive is applied at both first and second lateral edges of the first web. In some embodiments, spaced leg cutouts are formed in lateral edges of the web.

Abstract: This invention relates to absorbent pads, and methods for fabricating absorbent pads, having improved fluid intake and preferential wicking in the longitudinal direction. The absorbent pads have patterns of apertures which encourage the preferential wicking.

Abstract: An ultrasonic method for intermittently changing a condition of a workpiece is disclosed. The ultrasonic system includes an ultrasonic horn and a rotating anvil roll positioned to form a close relationship with each other comprising a nip. One of the ultrasonic horn and the rotating anvil roll includes an outer radial surface having a first length having a first amount of surface area per unit length of the respective outer radial surface, and a second length having a lesser amount of surface area per unit length of the respective outer radial surface. When ultrasonic energy is applied to the ultrasonic horn, the second length changes a condition of the workpiece when applied in the nip, but the first length does not change that condition. The change in condition occurs because the decrease in surface area along the second length increases the ultrasonic energy per unit area, as applied in the nip, to at least the threshold amount necessary to change the condition.
