Patent number: 5549928Abstract: A process for making an absorbent structure having a capillary substrate and regions of osmotic absorbent on the capillary substrate. The osmotic absorbent is cured from a liquid precursor applied to the capillary substrate. The capillary substrate has regions of topographically different elevations, taken normal to the plane of the capillary substrate. The capillary substrate is passed through a gap between a transfer roll and an anvil roll in a printing apparatus. The transfer roll has at liquid precursor on its periphery.

The oligo- and polyurethanes containing the oxadiazine trione ring are reaction products ofA polyisocyanates with a functionality of from 1.95 to 2.05, preferably from 1.99 to 2.01 andB compounds containing predominantly two zerewitinoff active hydrogen atoms, selected from hydroxyl and/or amino compounds in the molecular weight range of from 18 to 6000.under the condition that the ratio of isocyanate groups present in A to zerewitinoff active hydrogens present in B lies in the range of from 0.75:1 to 1.Type: GrantFiled: December 16, 1987Date of Patent: September 26, 1989Assignee: AGFA-Gevaert AktiengesellschaftInventors: Johannes Gerum, Heinrich Kober, Walter Meckel

Patent number: 4832983Abstract: A process for producing a metallized plastic film comprising the steps of applying a masking oil supplied from an oil supply source to the surface of a rubber roll drivingly in rotation and having formed on its surface projections or indentations in conformity with the margin pattern to be formed, applying the masking oil on the surface of the rubber roll to the surface of a plastic film in a pattern substantially similar to the margin pattern, and forming a vacuum-evaporated metal film on the oil bearing surface of the plastic film. Margins can be formed in a desired pattern efficiently by this process.Type: GrantFiled: March 5, 1987Date of Patent: May 23, 1989Assignee: Shizuki Electric Co., Inc.Inventors: Kyosuke Nagatomi, Teruki Kajiwara, Hisashi Ookuma, Ryo Tachibana

Patent number: 4826722Abstract: The invention relates to the forming of felts, the fibres of which are disposed in random directions.These felts are obtained by depositing the fibres which are carried by a current of gas on a gas-permeable conveyor, the fibres, prior to being deposited, being coated with a binder composition. The felt constituted on the conveyor is subject to at least a longitudinal compression, the intensity of which is regulated in such a way that no creases form on the surface.The felts obtained are highly resistant to compression, to tearing and to flexion.Type: GrantFiled: June 15, 1987Date of Patent: May 2, 1989Assignee: Saint-Gobain RechercheInventors: Alain Debouzie, Francois Bouquet, Alain De Meringo

Patent number: 4793837Abstract: An improved filter pad particularly useful to remove offensive pet odors emanating from animal crates and in aquariums is disclosed. The filter pad includes a base formed of unwoven, randomly oriented synthetic fibers impregnated with a mixture of zeolite particles and activated carbon particles effective to substantially reduce gaseous components having an offensive odor and discoloring agents in aquarium applications.Type: GrantFiled: January 15, 1988Date of Patent: December 27, 1988Assignee: Columbus Industries, Inc.Inventor: Jeffrey S. Pontius

Patent number: 4788100Abstract: A filter fabric comprises a needle felt substrate comprised of a non-woven air permeable fabric having spaced surfaces. An open pour air permeable plastic foam is incorporated into the substrate and extends from one surface toward the other.Type: GrantFiled: April 21, 1987Date of Patent: November 29, 1988Assignee: Thomas Josef Heimbach GmbH & Co.Inventors: Eberhard Janssen, Willi Hunold

Patent number: 4774110Abstract: A non-woven fabric suitable for clothing manufacture, comprising a fiber web substantially formed of a continuous filament of a synthetic fiber, wherein a plurality of weakened portions in a form of a scratch or a crack are distributed on the filament constituting at least one surface of the fiber web. Some of the weakened portions are broken to form free ends, some of which are projected from the fabrice surface to form a short fluff, and some of the remaining ends are embedded in the interior of the fiber web and entangled with the filament. The weakened portions of the filament are provided by nipping the fiber web between a pair of rollers, at least one of which has a rough surface formed of a plurality of prominences of hard particles. A punching treatment of the fiber web after the weakened portions has been imparted is effective for breaking the filament to form short fluffs on the fabric surface and for entangling the filaments with each other.Type: GrantFiled: October 23, 1987Date of Patent: September 27, 1988Assignee: Toray Industries, Inc.Inventors: Kakuji Murakami, Takashi Nakayama, Atsumi Morioka
