Abstract: A rotatable combination that includes first and second members respectively having first and second longitudinally extending pluralities of splines. The second plurality of splines extend substantially parallel to the rotational axis. The first plurality of splines includes first and second longitudinally extending sections having different orientations with the second longitudinal section defining an angle with the rotational axis. The first longitudinal section engages the second plurality of splines before the second longitudinal section during assembly of the two members. Engagement of the second longitudinal section with the second plurality of splines generates a greater resistance to longitudinal movement than engagement of the first longitudinal section with the second plurality of splines.

Abstract: A septic tank system including a tank and a downstream fluid system. The tank is adapted to receive sewerage and discharge liquid effluent into the downstream fluid system. A treatment chamber is located in the downstream fluid system and receives an ultraviolet light transmitting device which is removably insertable into the treatment chamber. A photoelectric device can be positioned in the downstream fluid system proximate the ultraviolet light transmitting device to monitor the operation of the device.

Abstract: Disclosed is a disposable absorbent article having a length and a width. The disposable absorbent article defines a first and second waist portion and a first and second longitudinal marginal portion. The disposable article includes the components of a backsheet layer, a topsheet layer, and an absorbent structure located between the topsheet layer and the backsheet layer. The article includes at least one elasticized area formed from an elastomeric, hot melt, pressure-sensitive adhesive, a first component and a second component, said first and second components being adhered to one another by said elastomeric, hot melt, pressure-sensitive adhesive.

Abstract: An apparatus and method for manufacturing a pad wherein a rotatable forming screen which has a generally cylindrical surface and at least one outwardly projecting nob is employed. The nob is positioned on the forming screen whereby the nob is circumscribed by the material, e.g., cellulosic fluff, deposited on the forming screen to form the pad. The pad is transferred from the forming screen to a moveable transfer surface. The transfer surface may be either flat or round and moves at a velocity which is at least as great as the velocity of the forming screen. The nob located on the forming screen includes a thrust surface disposed on a trailing edge of the nob. The thrust surface imparts a compressive force on the pad during the release of the pad from the forming screen. The compressive force is at least partially directed towards the transfer surface and thereby assists in the release and transfer of the pad. A vacuum may also be used to attract the pad to the transfer surface.

Abstract: An improved wet wipe includes a multiple layer basesheet to provide a unique combination of properties to the wipe which are not capable in a single layer basesheet. The layered basesheet includes at least two layers which include different fibers and have different physical properties. One of the layers may include polyethylene fibers to provide a soft, gentle feel for contacting the skin of the user during use while the other layer may include polypropylene fibers to provide strength and resiliency to the wipe to withstand the forces exerted by the user, and maintain its shape and integrity in use.
