摘要:
An elastic laminate that contains a nonwoven web bonded to an elastic layer is provided. The elastic layer contains one or more elastomeric polymers that are generally polar in nature, such as polyurethanes. To the contrary, the nonwoven web is formed from a material that is non-polar in nature. Nevertheless, one or more surfaces of the nonwoven web are fluorinated so that the resulting surface tension is increased. In this manner, the present inventors have discovered that, despite the difference in polarity between the layers, good attachment may be achieved without necessarily requiring an adhesive. Not only will such layers remained attached, but the functionality of the resulting laminate is also not adversely affected.

Absorbent articles with carefully controlled stretch properties are disclosed. In particular, the articles exhibit stretch not only in the lateral direction but also in the longitudinal direction. Specifically, the articles have a biaxial stretch ratio, which refers to a ratio of stretch along the hip circumference of the article to the amount of stretch in the longitudinal direction, that is from about 1.0 to about 2.5, and particularly from about 1.1 to about 1.5. Absorbent articles made in accordance with the present invention are capable of accommodating a relatively large size range of wearers. The articles also exhibit improved fit and prevent sagging or drooping of the crotch region, even after the crotch region has been wetted.

A method and apparatus for completing a natural solar distillation cycle (comprised of maritime trade winds being elevated over mountain formations to form orographic clouds) includes enabling the low cost harvesting of freshwater during time periods when weather conditions permit, despite the absence of rain. The cloud-catching wind management structures preferably incorporate minimal pressure drop gas cyclones to centrifuge condensate particles out of the air stream, and jet pump-like flow guide structures to help overcome pressure drop, for efficient, energy-passive production of freshwater utilizing only the stagnation pressure of natural wind velocity. The permanence (design and anchoring against natural disasters) of the structures provides for incorporation of water treatment means, and connection with permanent collection reservoirs and distribution systems, for large volume supply of potable freshwater for public and industrial use.

Absorbent articles having elastomeric end regions and methods of making such articles are disclosed. The absorbent article includes a bodyside liner and a garment-side outer cover. In particular embodiments, the liner includes a base layer of material and at least two strips or regions of elastomeric material attached to the base layer material with a space therebetween such that a center region of the base layer material is bordered on at least two end by composite regions of the elastomeric materials and the base layer material. In particular embodiments, the base layer material comprises a neckable non-extensible material. In other embodiments, the base layer material comprises an inherently extensible material. In certain embodiments, the composite region or regions can form a portion of the outer cover. Absorbent articles employing the material can have stretchable or elastomeric end regions.

A method for producing a machine direction and cross-machine direction elastic laminate includes the steps of providing a one direction elastic laminate material including at least one elastic layer and one facing layer and having a single direction of elasticity and coursing the one direction elastic laminate material through at least one stretching apparatus, such that the stretching apparatus stretches the laminate material in a direction perpendicular to the single direction of elasticity of the elastic laminate material, thereby producing a material that extends in a direction perpendicular to the direction of elasticity and also extends the elastic performance of the laminate in the single direction of elasticity.

A patient support device for supporting a patient at four points during back-related surgery. The device includes a generally rectangular frame having two opposing end members and two opposing side members. Two front posts are slidably mounted to one of the two end members. A travelling member is slidably mounted to both side members and may be displaced in a longitudinal direction between the two end members. Two rear posts are slidably mounted to the travelling member and may be displaced therealong, in a transverse direction between the side members. A front lead screw assembly is connected to the two front posts and allows simultaneous and opposing displacement of both front posts along the end member so that both front posts may be moved an equal distance from a center axis. Similarly, a rear lead screw assembly is connected to the two rear posts to allow simultaneous and opposing displacement of both rear posts along the travelling member. Each post includes a U-shaped channel to collectively accommodate a film cassette used in radiography. A conforming cushion is positioned above each post for contacting the patient.

A drug delivery device for delivering a drug either intermittently or to a pre-selected region of the gastro-intestinal tract, particularly to the colon, consists of an a solid core comprising an active agent coated with a delay jacket, then coated with a semi-permeable membrane which is optionally drilled to provide a release orifice, and then optionally further coated with an enteric material. The device delivers substantially all of the active agent to the targeted site.
摘要:
Absorbent articles with stretch direction properties are disclosed, having at least three stretch zones. A first edge zone and a second edge zone are separated by a middle zone. The middle zone, which may the same length as each edge zone, has different stretch-direction characteristics than the edge zones. The middle zone may stretch in a single direction, whereas the edge zones may stretch in a different single direction or in bi- or multi-axial directions. The flaps may be created from the edge zones. Through this construction, the absorbent article exhibits improved fit and appearance.
摘要:
A scoreboard clock having a front face including a plurality of display areas arranged to represent a scoreboard, indicia disposed adjacent each of the display areas, and a time means for generating chronological information elements and displaying the elements in the display areas. Each indicia indicates a selected information element related to a selected sporting event that is not related to the chronological information elements being displayed in the display areas.
摘要:
An improved mechanical fastening system that includes a male component and a female component is disclosed. The female component is adapted for releasable engagement with the male component, and the female component comprises a fibrous web, wherein the fibrous web comprises a layer of elastomeric fibers. A disposable absorbent article employing the improved mechanical fastening system is also disclosed.
