Patent number: 6284351Abstract: This invention describes two products both with a plain, fine textured, nonperforated surface visual consisting of a fiberboard substrate with or without a laminated porous nonwoven scrim and then a finished painted surface. The finish painted surface decorates or finishes the board, but most important, must remain acoustically transparent to retain the sound absorption properties of the fiberboard prior to painting. The fiberboard substrate is made to be porous or modified with hole perforations to cause it to be a good sound absorber. If the fiberboard substrate is sufficiently porous without hole perforations, then the sprayable, high solids, porous paint can be directly applied. If hole perforations are used to improve the sound absorption properties of the board substrate, then a porous, nonwoven scrim is attached and painted using the same high solids porous paint.Type: GrantFiled: March 24, 1999Date of Patent: September 4, 2001Assignee: Armstrong World Industries, Inc.Inventor: Darryl L. Sensenig

Patent number: 6276421Abstract: An apparatus for applying sheets to substrates including a rotating blade roller with a blade on its surface; a vacuum roller rotating with the blade roller, oriented parallel to the blade roller, and with a surface adjacent to the blade roller surface; at least one slot in the vacuum roller surface into which the blade is inserted as the rollers rotate; and a feeder for feeding a continuous sheet between the rollers so that the sheet is cut into segments. The vacuum roller surface includes surface holes connected to a vacuum source during cutting and disconnected after cutting and manifold holes parallel to the roller axis and located in a circle below the surface. The manifold holes have open ends located at one end of the vacuum roller and are connected to the surface holes. There is at least one plate adjacent the end of the vacuum roller with the open ends.

Patent number: 6197368Abstract: The disclosure is for an apparatus and a method of adhering particulate matter to limited areas of adhesive on a moving web and enabling the use of a very limited amount of particulate matter so that material costs are minimized. The path of a moving web with zones of adhesive and with previously supplied loose particles is shaped to form a trough with substantially vertical sides, so that gravity clears the web of excess material as the web moves down and up through the trough. Meanwhile, the particles falling from the web, go into the bottom of the trough where they stay until they stick to a following portion of the web which has adhesive. The loose particles are thereby immediately recycled for use, without any exposure to other contaminating materials, and the amount of particulate material used approaches the ideal quantity which would be needed to cover only the adhesive areas.Type: GrantFiled: July 7, 1999Date of Patent: March 6, 2001Assignee: Armstrong World Industries, Inc.Inventors: James P. Valenti, Edward M. Kohl

Patent number: 6187840Abstract: A textured metallocene polyethylene foam sheet suitable for use in a floor covering is made using a highly co-activated azodicarbonamide package which blows the metallocene polyethylene effectively. The preferred co-activators are zinc oxide and urea. The textured surface of metallocene polyethylene foam is formed by a chemical embossing process which utilizes a liquid triazole having an alkyl moiety as a foam-expansion inhibitor. The triazole is dissolved in a non-polar solvent to form the foam inhibitor. The preferred inhibitor is a hydrocarbon which may be halogenated.Type: GrantFiled: June 7, 2000Date of Patent: February 13, 2001Assignee: Armstrong World Industries, Inc.Inventors: Li-Ying T.

Patent number: 6156223Abstract: Thermally insulative xerogels and their preparation are described. To obtain these xerogels, an inorganic gel having hydroxyl moieties is reacted with a silicon-nitrogen compound which has a C.sub.1-6 hydrocarbon moiety on the silicon. Shrinkage of the gel during drying the gel is reduced and a more highly porous xerogel is obtained. The more highly porous xerogel has a low thermal conductivity which makes it a good thermal insulation.Type: GrantFiled: April 26, 1993Date of Patent: December 5, 2000Assignee: Armstrong World Industries, Inc.Inventors: Gary A.

Patent number: 6110439Abstract: A wet silica gel can be prepared by a process comprising the steps of contacting a stable, aqueous, fluid, silica system having a pH greater than 7.5 with an ion exchange resin which removes metal ions and replaces them with H+ ions and thereby reduces the pH to less than 5.0, adding an organic liquid to the aqueous silica system, providing, however, that the organic liquid added stays in one phase with the aqueous, silica, system, and does not cause the silica to precipitate, and adding a base to the silica system so that the pH of the silica system is in the range of from about 5.0 to about 7.5, and allowing the wet silica gel to form. The wet silica gel formed by this process is characterized by its high organic solvent content and the low concentration of basic metal ions.Type: GrantFiled: March 3, 1998Date of Patent: August 29, 2000Assignee: Armstrong World Industries, Inc.Inventors: Ravindra Deshpande, Lisa A.
