6378258, Apr 30, 2002

Filed:

Aug 18, 1999

Appl. No.:

09/376243

Inventors:

Richard Napoleon Cunningham - Aurora CO
Judith A. Wunsch - Willows CA

Assignee:

Johns Manville International, Inc. - denver CO

International Classification:

E04B 174

US Classification:

524041, 524043

Abstract:

An insulation sheet for insulating a wall, floor, ceiling or roof cavity is flexible, compressible and resilient and has lateral edges extending the length of the sheet. The lateral edges of the sheet are formed with contours along the lengths of the lateral edges, which with the flexibility, compressibility and resilience of the insulation sheet, increase the effective width of the sheet, relative to a conventional insulation sheet of the same length, width, thickness and density with straight lateral edges extending perpendicular between the major surfaces of the conventional sheet, with no or substantially no increase in the amount of insulation material forming the sheet relative to the insulation material used in the conventional insulation sheet. The contours of the lateral edges are formed by reciprocally oscillating cutting blades in a direction transverse to the feed of a sheet past the cutting blades and/or by placing the cutting blades at an angle other than perpendicular to the major surfaces of the sheet being fed past the cutting blades or by synchronously moving the cutting blades back and forth between a negative and a positive angle as the insulation sheet is fed past the cutting blades.

US Classification:

428143

Abstract:

A lightweight asphalt roofing product wherein the asphalt-based coating has a specific gravity less than 1. A lightweight filler is used which has an effective specific gravity in the range of 0. 10-0. 50 and is present in the coating in the range of 3%-25% by weight of the filled coating. In a preferred embodiment, the filler particles have hollow, gas filled inclusions, and comprise expanded perlite particles or expanded permicite particles.

International Classification:

US Classification:

Abstract:

A process for the rapid annealing of refractory fiber is disclosed. Air at a temperature of 750. degree. F. (400. degree. C. ) to 1400. degree. F. (760. degree. C. ) is passed through a refractory fiber body for a period of 5 to 200 seconds while the body is held securely in place for dimensional integrity. Apparatus for performing the process of this invention comprises an annealing unit containing opposed foraminous platens and means for passing hot air through the platens and through the fiber body retained between the platens or opposed foraminous belts and adjacent conduits and means for passing the hot annealing air through the conduits and belts and through the fiber body retained between the belts. The process and apparatus may be used to produce fiber bodies of a single material or laminated bodies of a plurality of interlocked layers, which may be of different fiber materials. The resultant products have excellent dimensional integrity, especially of the critical thickness dimension, and the process operates much more economically and thermally more efficiently than prior art tunnel oven processes.

US Classification:

93 84R

Abstract:

Apparatus is described for the formation of thermal insulation blocks from rolls of fibrous blankets. The apparatus comprises folding means to make alternating transverse folds in the blanket, insertion means to insert block supporting members (pronged beams) into and through folds of the block, and sequencing means to control the location of beam insertion according to a predetermined pattern.

Abstract:

A process for consistently making ceiling tiles having uniform density and surface texture includes using a conveyor along which trays are moved in a generally horizontal direction. A feeder box is used to deposit pulp in the trays, the pulp being comprised of a mixture of water, starch, fibrous material, and other ingredients. The feeder box through which pulp is deposited in the trays is of a special design, and includes a sloping front edge which creates a negative rake angle with respect to layers produced by the system. The lower front edge of the feeder box includes a surface having a compound curvature. Ceiling tiles are produced by the process having improved uniformity of density and surface texture.

International Classification:

B32B 3100

US Classification:

156260

Abstract:

The present invention relates to apparatus for forming a series of shingles from two shingle members. In the past such apparatus has required an inordinate number of hand operations and warehousing of such shingle members. These hand operations and warehousing functions have resulted in a substantial number of non-conforming shingles, which must be rejected, and also causing other problems which affect the overall productivity of such prior art apparatus. The present invention anticipates forming from stock material a complete set of such shingle members, maintaining the shingle members in a set in a predetermined positional relationship throughout the manufacturing operation up to and including the formation of stacks of shingles formed thereby. When such a set of shingle members includes a pair of overlay portions formed of interdigitated tabs, the present invention permits these tabs to be defined to form two styles of shingles. Since the set is maintained correlated throughout the laminating and stacking processes, these two styles of shingles can be placed on the roof in a predetermined pattern to enhance the aesthetic appeal of a roof covering made thereby.

Abstract:

A process for using shredded scrap or virgin fiber glass in combination with starch, water and other components to make ceiling tiles. The tiles are made by initially preparing a mixture of water, starch, boric acid and fire clay. That initial mixture is then heated to form a gel. Fiber glass is then added to the gel to form a pulp. The pulp is fed into trays to form slabs. The slabs are dried and finished into tiles.
