Abstract: An apparatus of parallel radiation for curing a resin to produce a resinous framework of a papermaking belt is provided. The apparatus comprises a source of radiation and an elongate reflector having an outer surface, an inner surface, a longitudinal axis, and two ends spaced apart along the longitudinal axis. The inner surface is comprised of a plurality of reflective facets oriented parallel to the longitudinal axis. In its cross-section, the reflector has a concave shape having a cross-sectional axis perpendicular the longitudinal axis. The reflective facets have a common focal point in the cross-section. The reflective facets direct radiation substantially parallel to the cross-sectional axis. Preferably, the plurality of reflective facets form the reflector's inner surface having a parabolic or circular macro-scale shape in the cross-section.
Abstract: Disclosed is a locking assembly for use with a pump-type dispenser to dispense material from a container. The assembly includes an actuator including at least one tooth integral to the actuator and a support ring which slidably engages the actuator. The support ring has at least one integral circumferential ridge with at least one ridge slot. The ridge is for limiting movement of the actuator until the tooth is properly aligned with the ridge slot, thereby allowing movement of the actuator and dispensing of product from the container. Alignment of the ridge slot and tooth may be achieved by rotating the actuator until an actuator position indicator on the actuator is aligned with an unlocking indicator on the support ring.
Abstract: Biodegradable fabric softener compounds that contain ester linkages a substantial level of polyunsaturation in the hydrophobic chains. The compounds can be used to form fabric softening compositions that are aqueous dispersions of the compounds. These compositions have a desirable low viscosity and recover, after freezing and thawing to have a stable low viscosity.

Abstract: Disclosed are absorbent cores for inclusion in articles such as diapers, incontinent briefs, training pants, diaper holders and liners, feminine hygiene garments, and the like, designed to provide improved fit and comfort for the wearer while adequately containing body exudates. The absorbent cores are designed so as to retain low levels of fluid in the crotch region, relative to the other core regions, even when the core absorbs significant amounts of fluid during use. To achieve this, the absorbent core is designed such that fluid is moved substantially from the crotch region to the front and/or rear ends of the article. In particular, the absorbent core comprises in its crotch region a distribution material having high fluid flux capabilities even after long periods of time. The material's flux properties reflect its ability to move significant amounts of fluid from the crotch of the core, even after long periods of time (e.g., 10 and 30 minutes).
Abstract: An improvement in a continuous process for making high internal phase emulsions that are typically polymerized to provide microporous, open-celled polymeric foam materials capable of absorbing aqueous fluids, especially aqueous body fluids such as urine. The improvement involves recirculating a portion (about 50% or less) of the emulsion withdrawn from the dynamic mixing zone of this continuous process. This increases the uniformity of the emulsion ultimately obtained from this continuous process in terms of having the water droplets homogeneously dispersed in the oil phase. This also improves the stability of the HIPE and expands the temperature range for pouring and curing this HIPE during subsequent emulsion polymerization. The improvement also eliminates the need for a static mixer outside the dynamic mixing zone, and allows for processing where relatively low pressure drops are required across the mixing zone.

Abstract: In a sanitary napkin, the retention layer of the absorbent core is covered by first tissue sheet of a density between 0.01 g/cm.sup.3 and 0.1 g/cm.sup.3 and by a second tissue sheet of a density between 0.08 and 0.3 g/cm.sup.3, the difference in density between the tissue sheets being between 0.01 g/cm.sup.3 and 0.2 g/cm.sup.3. The density gradient on top of the retention layer results in a relatively high efficiency of the retention layer and in efficient draining of the topmost tissue sheet, so that chances of rewet are reduced.
Abstract: A dispenser comprises an upper portion having an annular member depending therefrom and a bottom portion having a base and an upright post connected to the base. It also includes a flexible bag capable of containing fluid suspended from the upper portion and located inside the annular member. The flexible bag has a nozzle connected to it such that the flexible bag is closed except at the nozzle. The nozzle has a discharge orifice in fluid communication with the flexible bag. The upper portion telescopingly engages the bottom portion such that the upright post is located substantially aligned with the flexible bag. The upright post is sized to cause the flexible bag to invert when the upper portion and the bottom portion are pressed together. An openable closure closes the discharge orifice so that a fluid-containing flexible bag may be easily handled for replacement of the emptied flexible bag in the dispenser.
