Stephen Clark Smith has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7510758
    Abstract: A breathable, elastic, film laminate including layers of an inherently breathable, elastic polymer film alternately stacked with layers of a filled plastic polymer. The laminate may be made by grafting a thermoplastic polymer to an elastomer to form an inherently breathable elastic polymer, extruding, the elastic polymer through a die, extruding the filled plastic polymer through a die, stacking the extruded elastic polymer with the extruded plastic polymer while the polymers are in a melt-extrudable state to create a multilayer film laminate, and stretching the laminate.
    Type: Grant
    Filed: November 12, 2002
    Date of Patent: March 31, 2009
    Assignee: Kimberly-Clark Worldwide, Inc.

  • Patent number: 6706135
    Abstract: A process for temporarily stabilizing an extensible material while incorporating the material into a garment, or while performing any other converting process on the material. The stabilizing process includes the step of selectively bonding regions of the extensible material to provide a bonded material having restricted extensibility. The bonded material can be put through a converting process, such as winding the bonded material onto a roll, spooling the bonded material, slitting the bonded material, laminating the bonded material, or incorporating the bonded material into a garment. After the bonding material has gone through the converting process, the bonded regions can be removed from the bonded material.

  • Publication number: 20020076520
    Abstract: A fastening system wherein complementary components each have engaging elements protruding from a backing, and an attractive magnetic force applied through the complementary components. The attractive magnetic force can be supplied by external magnets attached to the backings, or by using a magnetic composite to form the backings and/or the engaging elements. The fastening system is particularly beneficial when used in absorbent articles.

  • Patent number: 5853881
    Abstract: A composite elastic material is provided having improved hysteresis comprising a layer of an elastic material bonded to a layer of nonelastic material at least one side. The elastic material layer is made from a blend of a narrow polydispersity number polymer and a conventional elastomer, and the blend is essentially free of low molecular weight polyethylene processing aids. The composite elastic material laminate should have a hysteresis at least 15 percent better than a similar laminate made without the narrow polydispersity number elastomer but with the processing aid.

  • Patent number: 5804021
    Abstract: The present invention is directed to elastic fibrous nonwoven web laminates which exhibit elastic properties in at least one direction and, if desired, two or more directions due to the use of at least one fibrous nonwoven web facing layer which contains a plurality of slits. The resultant laminates are useful in a wide variety of applications not the least of which include garments, surgical drapes and other supplies as well as personal care absorbent articles including diapers, training pants, sanitary napkins, incontinence garments, bandages and the like. Processes for forming such laminates are also disclosed.
