| 20130040108 | MODIFIED FIBERS FOR USE IN THE FORMATION OF THERMOPLASTIC FIBER-REINFORCED COMPOSITE ARTICLES AND PROCESS - A surface-modified fibrous material is provided for incorporation in a thermoplastic matrix to form a fiber-reinforced composite article. Good binding between the fibrous material and the thermoplastic matrix is achieved through the presence of finely roughened surfaces on the fibers of nanoparticles of an inorganic material. Such nanoparticles are provided from an alkaline aqueous size composition containing the nanoparticles dispersed therein (as described). The fibrous material may be provided in continuous or discontinuous form. In a preferred embodiment glass fibers are initially provided in continuous form followed by cutting into discontinuous lengths and drying with the retention of the nanoparticles on the surfaces of the fibers. The surface-roughened fibrous material is incorporated in a thermoplastic matrix as fibrous reinforcement with the application of heat whereby the thermoplastic matrix is rendered melt processable. In preferred embodiments injection or compression molding is utilized. Improved long-fiber thermoplastics also may be formed to advantage. | 02-14-2013 |
| 20130123406 | FORMALDEHYDE FREE BINDER COMPOSITIONS FOR FIBROUS MATERIALS - Compositions for binding organic or inorganic fibers is described. The compositions may include an aqueous solution having a pH of about 4.5 or more. The aqueous solution may include a polycarboxy polymer that is about 10%, by wt., to 100%, by wt., of a butenedioic acid or butenedioic anhydride; and a polyol. The compositions can maintain a pH of about 5 or more after being cured into a thermoset plastic with the fibers. Processes for preparing a binder composition for organic or inorganic fibers are also described. The processes may include providing an aqueous solution of polycarboxylic acid polymers, where the polymers comprise about 10%, by wt., to 100%, by wt., of a butenedioic acid or butenedioic anhydride; adding a polyol to the aqueous solution; and maintaining the pH of the aqueous solution at about 5 or more. | 05-16-2013 |
| 20130139470 | ROOFING SYSTEM INCLUDING ROOFING COMPONENTS AND METHODS - A roofing system includes a plurality of insulation boards adapted for overlying a roof deck to form a layer of insulation, and a plurality of cover boards adapted for overlying the layer of insulation. Each insulation board includes a foam material that includes polyisucyanurate, the foam material having a first density. Each cover board includes a material including polyisocyanurate, the material having a second density greater than the first. The roofing system may further include a waterproofing membrane adapted for overlying the cover boards. The insulation boards and cover boards may include facers on top or bottom surfaces. | 06-06-2013 |
| 20130139471 | MANUFACTURING AND ASSEMBLY OF ROOFING COMPONENTS - A method includes dispensing a first polymer or predominantly polymer material foam precursor and allowing the precursor to rise and at least partially set to form a foam core layer for an insulation board, the foam core layer having a first density. The method further comprises dispensing a second polymer or predominantly polymer material foam precursor and allowing the second precursor to rise and set to form a core layer for a cover board, the core layer for the cover board having a second density greater than the first density. The second foam precursor may include polyisocyanurate. The method may also include feeding facer materials over the precursors to form facers on the core layers. Such insulation boards and cover boards may be cut to length and installed on a roof. | 06-06-2013 |
| 20130145722 | ROOFING SYSTEM INCLUDING INSULATION AND COVER BOARDS - A roofing system includes a plurality of insulation boards adapted for overlying a roof deck to form a layer of insulation, and a plurality of cover boards adapted for overlying the layer of insulation. Each insulation board includes a polymer foam material having a first density. Each cover board includes a material including polyisocyanurate, the material having a second density greater than the first. The foam material of the insulation boards may include, for example, polystyrene, polyurethane, or a phenolic material. The insulation boards and cover boards may include facers on top or bottom surfaces. | 06-13-2013 |

| 20130157030 | BINDER-CONSOLIDATED TEXTILE FABRIC, METHOD FOR PRODUCING IT, AND USE THEREOF - The invention relates to a novel binder system and its use for bonding textile fabrics as well as products containing such bonded textile fabrics. The materials of the invention are suitable for the manufacture of lining materials which can be used in the manufacture of sarking membranes, roofing sheets and water-proof sheetings, in particular of coated sarking membranes, roofing sheets and water-proof sheetings, or in the manufacture of carpets and PVC floorings as a textile backing or as a textile reinforcement. | 06-20-2013 |
| 20130160497 | TRANSVERSE ROW BUSHINGS AND METHODS WITH FREEDOM OF MOVEMENT - An exemplary bushing system utilizes a bushing having a bottom plate having a plurality of holes from which filaments are drawn, and a plurality of support-receiving elements that are each configured to receive an elongated support. The support-receiving elements extend through the bushing generally along a longitudinal axis. A frame supports the bushing and includes a pair of horizontal rails upon which the supports rest. The horizontal rails comprise a treated surface that permits movement of the elongated supports relative to the frame in the longitudinal direction as the bushing expands and contracts due to thermal heating and cooling. | 06-27-2013 |
