The article is then conditioned at an elevated temperature greater than or equal to a glass transition temperature (Tg) of a hard phase of the thermoplastic block copolymer. The article is stretch-thinned at the elevated temperature to a desired percentage stretch, forming a stretch-thinned article, after which it is cooled to a temperature below the glass transition temperature of the hard phase of the thermoplastic block copolymer. Films produced by this method are suitable for use in durable and disposable articles including personal care articles such as diapers, incontinence wear, training pants, and feminine care articles, as well as wound dressings, wipes, towels, napkins, and protective apparel.Type: GrantFiled: April 14, 2000Date of Patent: October 8, 2002Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Jack Draper Taylor, Timothy Ray Martin

Patent number: 6450722Abstract: A method of making a head for a semisolid product dispenser, such as a gel deodorant dispenser, comprises the steps of: providing a piece of porous media having a desired shape with a perimeter and openings through the media in the area inside of the perimeter, compressing at least the portion of the media inside of the perimeter between two parts of a hard tool so as to crush the media, thereby reducing the size of the openings, and affixing the porous media to a head frame to form the semisolid product dispenser head. Preferably the porous media is affixed to the head frame by an insert injection molding process, and the media is crushed in the same mold tool as is used to mold the head frame.Type: GrantFiled: July 3, 2000Date of Patent: September 17, 2002Assignee: Filtertek Inc.Inventors: Rick R. Ruschke, Brian J. Franzene, Edward Kandel

Patent number: 6156254Abstract: A method of manufacturing a balloon portion for a balloon catheter for radially expanding a vessel in the body of a mammal, which catheter comprises a tube portion with a passage therethrough and a hollow expandable balloon portion defined by a fluid impervious wall and secured to the tube portion, which balloon portion can be inflated and deflated by means of a fluid passed through the passage, such that:a. the wall of the balloon portion is formed from a flexible substantially fluid impervious material having re-inforcing fibers formed integrally with the wall material; andb. the balloon portion is preformed to the desired radial diameter at its inflated state having smaller diameter end portions and a wider diameter portion intermediate the said ends and has a substantially uniform wall thickness.Type: GrantFiled: February 1, 1999Date of Patent: December 5, 2000Assignee: Ranier LimitedInventors: Geoffrey Thomas Andrews, Robert Adam Snell

Patent number: 6030568Abstract: A method for producing a fibre reinforced three-dimensional product comprises depositing of long fibers in a mould consisting of a frame in which a carrier net for the fibers is suspended. The individual layers of a formed plane laminate are positioned in such a manner that only a first end is secured at a frame side. Said first ends are secured at different frame sides. In this manner it is possible, in a pressing procedure giving the product is three-dimensional shape, to obtain a virtually even distribution of the fibres, even in areas which are subjected to the longest move away from the plane original laminate. In this manner sound well-defined properties are obtained in the three-dimensional product formed.Type: GrantFiled: December 20, 1996Date of Patent: February 29, 2000Inventor: Torben Vestergaard

Patent number: 6017429Abstract: The present invention relates to an improved cathode element for the production of electrolytic copper, and more particularly to an improved cathode element of the reusable type which includes a cathode plate. With the intention of preventing a sleeve-like copper build-up around the cathode plate, the cathode element is provided with electrically insulating edge strips along at least those side edges of the cathode element which, in an active position, are located in the electrolyte bath, wherein the electrically insulating edge strips are chemically bonded to the cathode plate, preferably by vulcanization or by gluing.Type: GrantFiled: May 27, 1998Date of Patent: January 25, 2000Assignee: Svedala Skega ABInventor: Sture V. Persson

Patent number: 6006643Abstract: To prevent a long molding from bending during drying and hardening in a drying furnace after braiding. A pair of rotatable joints 2 and 3 are used as a stretching jig for a long braiding mandrel, the joints are connected to the respective ends of the mandrel, and a loading means 16 is used to stretch the mandrel via the joints to apply tension to it.Type: GrantFiled: August 26, 1998Date of Patent: December 28, 1999Assignee: Murata Kikai Kabushiki KaishaInventor: Masao Hirukawa

Patent number: 5908596Abstract: A method for manufacturing a shaped panel from a continuous length of an expanded mat. The method includes transporting an expanded mat on a conveyor. The conveyor includes side chains and a plurality of spaced apart slats, which extend transversely between the side chains, on which the expanded mat is supported. The side chains and the plurality of slats define a plurality of openings in the conveyor. A length of the expanded mat is confined and shaped between a male mold and a female mold by moving the male mold and the female mold into mating relationship through one of the plurality of openings in the conveyor.Type: GrantFiled: July 24, 1997Date of Patent: June 1, 1999Assignee: Nicofibers, Inc.Inventors: Rodney R. Wilkins, Carl J. Weaver, Donald E. Dickson, Jack E. Compston

Patent number: 5879607Abstract: A protective, impact resistant material and method which includes a fabric of thermoplastic polymeric fibers having a strength of at least 0.5 GPa and an elastic modulus of at least 25 GPa and a matrix of polymeric material disposed in the interstices between the fibers having an elastic modulus of 0.2 to 3.times.10.sup.6 psi. The polymeric fibers can be gel spun, polyethylene, polypropylene, nylon, polyvinyl alcohol and polyethylene terephthalate. In a second embodiment, the matrix is derived from the fabric.Type: GrantFiled: March 29, 1996Date of Patent: March 9, 1999Assignee: Raytheon TI Systems & University of MassachusettsInventors: Paul Klocek, William J.

Patent number: 5833898Abstract: A method for manufacturing a resin-impregnated endless belt structure is carried out on an apparatus having an outer cylinder having an inner cylindrical surface coaxial with a smaller radius cylindrical mandrel. An endless base structure for the endless belt structure is disposed within the outer cylinder on the inner cylindrical surface. The cylindrical mandrel, having an inwardly curved nose, is then inserted into the outer cylinder forming a nip of converging geometry between the nose and the inner cylindrical surface. Polymeric resin material is dispensed continuously into the nip while the cylindrical mandrel is gradually moved completely into the outer cylinder. The nose forces the polymeric resin material into the endless base structure, and air bubbles out, while forcing the endless base structure against the inner cylindrical surface.Type: GrantFiled: October 10, 1996Date of Patent: November 10, 1998Assignee: Albany International Corp.Inventor: William H. Dutt
