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.

This painted scrim must be sufficiently optically opaque to hide the hole punched board, yet sufficiently open to render it acoustically transparent.Type: GrantFiled: November 9, 1995Date of Patent: February 23, 1999Assignee: Armstrong World Industries, Inc.Inventors: James D.

Patent number: 4997323Abstract: Resilient tile within 0.005 inches of square and having sides within 0.005 inches of each other may be produced by positioning unfinished tile on a continuous belt. One edge adjacent the trailing edge of each tile is made to contact a stop means while the trailing edge is made to contact two independently adjustable dogs on the continuous belt. The tile is held down by hold-down rollers while the tile is so positioned. The two edges adjacent the trailing edge are edge finished, preferably by two cylindrical shaper routers. The tile is then positioned on a second continuous belt with one of the finished edges becoming the trailing edge and the remaining two edges being edge finished.Type: GrantFiled: June 22, 1989Date of Patent: March 5, 1991Assignee: Armstrong World Industries, Inc.Inventors: Joseph L. Giandalia, Darryl L. Sensenig

Patent number: 4654244Abstract: The present invention concerns loose-lay floor structures comprising at least two layers of reinforcing material and processes to design and produce them. Loose-lay floors may be designed which will be suitable for use over stable subfloors, or which will accommodate the movement of very unstable subfloors. Flooring constructed according to this invention will have the ability to resist buckling, curling and doming, and will resist moving under a rolling load. A process is also provided for modifying structures comprising a single reinforcing layer in situ so as to convert structures with unacceptable buckling characteristics into structures with acceptable buckling characteristics. As an alternative, the reinforcing layer may be premodified such that, when used to provide a surface covering, the covering will have acceptable buckling characteristics.Type: GrantFiled: July 27, 1984Date of Patent: March 31, 1987Assignee: Armstrong World Industries, Inc.Inventors: Donald C. Eckert, J. Richard George, George L. Lilley, Darryl L. Sensenig, James A. Tshudy

Patent number: 4552606Abstract: A substantially non-overlapping tightly packed layer of plastic chips is formed and attached to the surface of a substrate by a method in which the chips are dispersed onto the surface of a liquid, flowing from a first location to a second location. The rate of flow of the surface of the liquid is reduced at the second location to cause the chips to pack together in a single-chip-thickness layer. The layer of chips is then removed from the liquid by passing a porous web upward at an angle from below the liquid surface through the chip layer-liquid interface. The chip layer is then transferred to a heat-sensitive transparent adhesive coating on a suitable prepared substrate and secured thereon by means of heat and pressure. A resinous wear layer which is transparent after fusion is then applied.Type: GrantFiled: March 7, 1983Date of Patent: November 12, 1985Assignee: Armstrong World Industries, Inc.Inventors: Timothy D. Colyer, Darryl L. Sensenig
