Inventor: HAYES RICHARD ALLEN
IPC: D06M15/263
Filed: 1999-06-30
Abstract: Compositions and textile sizes based on those compositions, which are particular poly(vinyl alcohol) copolymer ionomers, as well as blends of thos e ionomers with other sizing polymers are described. A process to prepare the ionomers is described. The compositions are poly(vinyl alcohol) copolymers which have carboxylic acid ionomer comonomer units. Sizes based on these ionomers are aqueous solutions of the ionomers or solutions of blends of the m with other poly(vinyl alcohol) polymers which are not ionomeric, or solution/suspensions of the ionomers with various starches, or both. Desizin g in either water or caustic solutions is generally far superior to comparable  polymer blends which contain no poly(vinyl alcohol) copolymer ionomer.</SDOA B>

Title: Disposable absorbent articles with improved liquid absorption and retention
Inventor: KLEMP WALTER V
IPC: A61F13/15
Filed: 1999-07-13
Abstract: An absorbent disposable garment (10) such as a diaper, incontinence pant, or  a training pant, having a unitary cuff (34) is disclosed. The construction of the unitary cuff (34) provides improved comfort to the wearer's leg in the cuff area, a tighter seal around the leg to prevent leakage, and achieves these results utilizing simpler manufacturing processes. The unitary cuff (3 4) does not require an additional separate leg gasket cuff. The unitary cuff ha s a proximal edge (152) attached to or extending from the disposable garment (10); an edge (154) distal from the disposable garment; and exhibits elasticity along a width between the distal edge (154) and proximal edge (152). The elasticity (B), nearer the proximal edge (152) has a higher contractile force than the elasticity (A) near the distal edge (154) (i.e., near the wearer's leg) of the unitary cuff.
Patent CA-2339104-A1 (CA)
Inventor: INGLE FRANK W
IPC: A61B18/00
Filed: 1999-07-22
Abstract: The invention provides improved devices, methods, and systems for repeatable, for reliably contracting fascia, and other support tissues, particularly for the treatment of urinary incontinence. A probe surface (24) includes at least one heating element (26) with a heating area, and at least one cooling element with a cooling area. The heating, and cooling areas are interspersed along the probe surface so as to produce alternating heated, and cooled regions across a tissue engaged by the probe. Sufficient controlled energy is transmitted from the surface into the engaged tissue to contract the tissue, and inhibit incontinence (or otherwise provide the desired therapeutic results). The interspersed cooling element helps decrease trauma to the tissue for a given amount of shrinkage.

Title: Electro-optical semiconductor device with a polyimide/silicon oxide bi-layer beneath a metal contact layer
Inventor: LU HANH
IPC: H01S5/223
Filed: 1999-07-29
Abstract: An electro-optical, ridge-waveguide device (10) and method for its fabricati on utilizes a polyimide ridge-protection layer (116), which provides good ridge  protection/planarization while minimizing parasitic capacitance. A silicon oxide interlayer (118) is used between a metal contact layer (112) and the polyimide. This interlayer facilitates the adhesion between the metal contac t layer (112) and the underlying device (108) since good adhesion can be obtained between the silicon oxide layer and the polyimide layer and between  the metal layer and silicon oxide layer. Preferably, the polyimide is roughened to increase the surface area contact between the polyimide layer (116) and silicon oxide layer (118) to further increase adhesion and thus th e pull-off force required to separate the metal contact layer (122) from the device. While such roughening can be achieved through plasma etching, in a preferred embodiment, the polyimide layer (116) is roughened by patterned etching. Specifically, a patterned photoresist (154) is used as an etch- protection layer to form a series of wells in the polyimide layer that have a pitch between 1 and 20 microns.

IPC: H01M8/021
Filed: 1999-12-23
Abstract: A metal oxide ceramic material such as alumina or chromia which has been rendered electrically conductive through its thickness by the incorporation of silver into the material. The metal oxide ceramic material may be in the form of a layer on a substrate such as a bipolar plate or other component for a fuel cell assembly. The electrical conductivity may be achieved by heating the ceramic material and a silver-containing material in contact with each other to at least 750 °C such that silver migrates from the silver-containing material into the metal oxide ceramic material and creates electrically conductive pathways through the ceramic material. In a particular embodiment, the substrate is a steel which forms an alumina, chromia or alumina-rich or chromia-rich surface layer in oxidising atmosphere and the silver-containing material is heated in an oxidising atmosphere in contact with the steel to cause the surface layer to form on the steel and to cause silver from the silver-containing material to occur in and create the electrically conductive pathways through the layer. The silver-containing material may be commercially pure silver or other forms of silver.
