Filed:

Mar 4, 1985

Appl. No.:

6/707908

Inventors:

Kenneth F. Halls - Arvada CO

Assignee:

Acoustic Industries, Inc. - Golden CO

International Classification:

B32B 3500

US Classification:

156 98

Abstract:

A method and apparatus for on-site repair and refinishing of building panels that have been discolored or worn is provided. In one embodiment, worn acoustical tiles are first removed from their installed location ceiling and worn parts are cut off. Replacement parts are then fitted to the remaining portion of the worn tile and adhesively attached. The repaired tile is then sprayed with adhesive and a sheet of decorative material is attached. Finally, the repaired tile with the decorative material attached is run through pinch rollers, resulting in a neat and secure bonding. The tile is then re-installed in its original location with the decorative material exposed. In another embodiment, a worn or discolored ceiling tile is removed from the ceiling and placed into a pre-fit, semi-rigid decorative covering. The tile and decorative covering are then replaced in the ceiling in the original position of the tile with the decorative covering exposed.

International Classification:

B08B 504

US Classification:

134 21

Abstract:

A method and apparatus for cleaning a surface using a high velocity stream or streams of cleaning fluid. The high velocity stream or streams issue from one or more nozzles that are moving at a high velocity relative to the surface to be cleaned. In a preferred embodiment, three nozzles are mounted to a common hub member with two of the nozzles directed at the carpet so that they tend to move the hub member in a first direction about the axis of rotation. The third nozzle is directed at the carpet so that it tends to move the hub member about the axis of rotation in a second direction opposite to the first. The first two nozzles determine the direction of rotation and the third nozzle is then moved relative to the surface so that the velocity imparted to the stream issuing from the third nozzle because of its motion adds to the existing velocity of the stream due to the high pressure alone of the source of the cleaning fluid. This embodiment has been found to work particularly well on carpets.

US Classification:

156 92

Abstract:

Disclosed is a system for covering installed ceiling tiles without removal of the tiles from the ceiling. The system includes a novel facing for covering an installed ceiling tile, a method of applying the facing to the face of an installed tile and apparatus for carrying out the method. The novel facing includes a panel of at least semi-rigid material having a decorative surface, an underside surface and a flexible border which extends at an angle from and about the periphery of the decorative surface. The panel's underside surface is prefit to cover the face of an installed ceiling tile and is provided with selectively located pins which project from the underside surface of the facing. The disclosed method includes providing the aforementioned decorative facing and marking the face of the tile to provide selectively located marks on the face of the tile which are capable of aligning with the facing's selectively located pins to center the facing on the tile. After marking the tile, the decorative facing is positioned up against the tile so that its pins are in contact with and aligned with the alignment marks provided on the face of the tile.

International Classification:

B32B 3500

US Classification:

156 94

Abstract:

Disclosed are a method and apparatus of refinishing a building panel such as a acoustic ceiling panel or tile. The method includes placing the building panel to be resurfaced on a support surface having a plurality of perforations. The building panel is placed so that its back surface is in contact with the perforated support surface. The perforations extend beyond the building panel's side edges. An adhesive is applied to one side of an air impervious sheet or film. The coated sheet or film is placed over the decorative surface of the building panel and over the exposed perforations in the support surface which are located beyond the building panel's side edges. Vacuum is drawn between the sheet or film and the perforated support surface via the perforations which is sufficient to enable ambient air pressure to force or collapse the sheet tightly against the decorative surface so that the sheet substantially assumes or conforms to the contour of the building panel's decorative surface. When the adhesive dries or cures, the sheet will be tightly adhered to the decorative surface of the building panel. A preferred embodiment employs means for heating the adhesive to expedite its heating or curing.
