  • Patent number: 7329456
    Abstract: A method of forming a box-like acoustical substrate is provided. Portions of an acoustical substrate having a decorative surface are compressed to form a flange, a first compressed region, a second compressed region, and a third compressed region. First, second, central, and third uncompressed regions are positioned respectively adjacent to the compressed regions. A left first surface and a right first surface of the acoustical substrate may be folded toward the back surface of the substrate until the second compressed region and the third compressed regions are flush with the central uncompressed region. An outer portion of the left surface may then be folded towards the back surface until the flange is flush with the right edge. The acoustical product may be used as an acoustical trap or duct. When the acoustical product is utilized as a duct, an air impermeable sheet may be positioned on the external surface.

  • Patent number: 7326304
    Abstract: A neutralization system for controlling the pH of the washwater used to clean and maintain polyacrylic bound glass forming equipment is provided. The neutralization system introduces a base solution to a washwater solution when the pH of the washwater solution contained in a closed loop washwater recovery system and in a washwater tank holding the washwater solution is determined to be below approximately 8.0. Maintaining the pH of the washwater solution reduces the corrosion rate of the glass fiber forming equipment that is typically associated with acidic binders. In a second embodiment of the invention, a closed-loop hoodwall reclaim washwater recovery system utilized in addition to the washwater neutralization system that allows for the recovery and reuse of a polycarboxylic acid binder with a minimal amount of base solution. The closed-loop hoodwall reclaim washwater system is not connected to the closed-loop washwater neutralization system.

  • Patent number: 7308803
    Abstract: Provided is an assembly for insulating substantially vertical runs of cooled surfaces that are continuously or periodically exposed to air or another gas that has a dewpoint temperature above that of the cooled surface, thereby resulting in condensation water vapor on or adjacent the cooled surface. One embodiment of the insulating assembly provides a wicking material layer adjacent the cooled surface that, in combination with transporting and evaporating structures, removes the condensate from the vicinity of the cooled surface and allows for its evaporation into the ambient gas surrounding the exterior surface of the insulating assembly. Another embodiment provides for exposing the condensate to an internal conditioned gas stream to provide for evaporation that does not necessarily utilize an exterior surface. Both embodiments remove condensate from the insulating structure and thereby tend to avoid any substantial condensate accumulation and maintain the insulating performance.

  • Patent number: 7294218
    Abstract: A method of forming a multilayer insulation material formed of an acoustical composite layer and a first thermal layer is provided. The acoustical and insulting layer is formed of a polymer based thermoplastic material and reinforcing fibers. Preferably the reinforcing fibers are wet use chopped strand glass fibers (WUCS). The acoustical composite layer may be formed by opening the WUCS fibers, blending the reinforcement and polymer fibers, forming the reinforcement and polymer fibers into a sheet, and then bonding the sheet. A first thermal layer formed of one or more polymer based thermoplastic organic materials is then positioned on a first major surface of the acoustical composite layer. A second thermal layer of polymeric fibers may be optionally positioned on a second major surface of the acoustical composite layer. The multilayer acoustic material may be utilized in semi-structural and acoustical applications.

  • Patent number: 7281622
    Abstract: A conveyor assembly is configured to convey and maintain compression of multiple compressible batts. Adjacent pairs of conveyor systems within the conveyor assembly define a space between the pair of conveyor systems for receiving and conveying compressible batts. Each pair of adjacent conveyor systems has at least two upper belts in a coplanar relationship. One of the two upper belts travels in an advancing direction and other upper belt travels in a returning direction. Each pair of adjacent conveyor systems also has at least two lower belts in a coplanar relationship. One of the lower belts travels in the advancing direction and the other lower belt travels in the returning direction.

  • Patent number: 7279059
    Abstract: An acoustical and thermally absorbent chopped strand mat formed of thermoplastic bonding materials and bundles of reinforcing fibers is provided. The reinforcing fibers are preferably wet use chopped strand glass fibers (WUCS). The thermoplastic bonding materials may be any thermoplastic or thermosetting material having a melting point less than the reinforcing fiber. The chopped strand mat may be formed by partially opening the WUCS fibers and filamentizing the thermoplastic bonding materials, blending the reinforcement and thermoplastic bonding fibers, forming the reinforcement and thermoplastic bonding fibers into a sheet, and bonding the sheet. During bonding, the sheet is heated to a temperature above the melting point of the thermoplastic bonding fibers but below the temperature of the glass fibers. The melted thermoplastic bonding fibers act as a glue to hold the glass fibers in bundles. The chopped strand mat thus formed may be used as a reinforcement material in automotive applications.

  • Patent number: 7267782
    Abstract: A two-part sizing composition including a precursor size composition and a binder composition, the binder composition being substantially free of any aminosilane coupling agent for is provided for the production of reinforcing fiber materials that exhibit little or no coloration. The two-part sizing composition may be advantageously employed to make substantially colorless, densified fiber pellets of a reinforcing fiber material. The densified fiber pellets may be produced by applying the sizing composition to reinforcing fiber strands, chopping the reinforcing fiber strands to form chopped strand segments, applying the binder composition, and palletizing and densifying the coated chopped strand segments to form flowable densified fiber pellets.
