Patent number: 8628865Abstract: The invention relates to a method for producing a sheet from renewable raw materials. In the method, after mixing a composition to produce a sheet from renewable raw materials, this composition is applied to a conveyor belt. Protruding materials or unevennesses are eliminated with the aid of a device, preferably a simple doctor blade. Without supplying heat, the composition is then subjected to a first drying process on the conveyor belt, before the endless sheet created in this way is cut into sections. The sections are then passed on to final drying in a storage device. After complete drying, regions at the extremities of the sections that have been adversely affected by cutting up the endless sheet are removed from these sections and chopped up into chips. These chips are returned to the further production process in a final method step by feeding them into the composition for producing a sheet from renewable raw materials.Type: GrantFiled: July 6, 2009Date of Patent: January 14, 2014Assignee: Strohlos Produktentwicklung KGInventor: Christian Losehand

Patent number: 8484922Abstract: The invention is directed to a composite foam material that is alkaline and heat resistance. The composite foam material comprises a foam layer that having a film layer attached thereto and in which at least one of the film or foam layers includes a carbon free radical scavenger agent that is dispersed therein. The carbon free radical scavengers neutralize free radicals that are generated in the polymeric material (e.g., film or foam layer) and help prevent the degradation of the foam composite material. In particular, foam composite materials in accordance with the present invention can be used in underlayment applications in which exposure to heat can degrade the underlayment. As a result, the durability and useful life of the composite sheet material can be extended. In some embodiments of the present invention provides a floor underlayment material that overcomes many of the problems discussed above.Type: GrantFiled: February 17, 2010Date of Patent: July 16, 2013Assignee: Sealed Air Corporation (US)Inventors: Shau-Tarng Lee, Claes Hermansson, Brent Sholl

Patent number: 8481168Abstract: The present disclosure describes various building materials used in the building and construction industry, and to buildings or objects constructed therefrom, and to methods of making these building materials. The building materials comprise a polymeric material, such as sodium alginate and/or calcium alginate which confers significant flame-, fire- and heat-resistance or imperviousness to the materials. Other substances can be added to the materials to improve cross-linking and/or to produce resistance to fungal degradation. The building materials which can be produced, processed, or treated using the alginate polymers of the invention include, but are not limited to, wood products; masonry products; wall, roofing, flooring and siding products; and paint products. Further, sodium alginate in the form of a gel may be used as a firebreak to effectively stop the advance of grass fires, wildfires, and forest fires.Type: GrantFiled: July 19, 2012Date of Patent: July 9, 2013Assignee: Tamarisk Technologies, L.L.C.Inventor: Daniel R. DeBrouse

Patent number: 8470461Abstract: The invention generally provides gypsum-containing slurries including stucco, naphthalenesulfonate dispersant, and pregelatinized starch. The naphthalenesulfonate dispersant is present in an amount of about 0.1%-3.0% by weight based on the weight of dry stucco. The pregelatinized starch is present in an amount of at least about 0.5% by weight up to about 10% by weight of pregelatinized starch by weight based on the weight of dry stucco in the formulation. Other slurry additives can include trimetaphosphate salts, accelerators, binders, paper fiber, glass fiber, and other known ingredients. The invention also comprises the gypsum-containing products made with such slurries, for example, gypsum wallboard, and a method of making gypsum wallboard.Type: GrantFiled: June 11, 2012Date of Patent: June 25, 2013Assignee: United States Gypsum CompanyInventors: Qiang Yu, Weixin D. Song, Michael R. Lynn

Patent number: 8470436Abstract: 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.Type: GrantFiled: February 4, 2013Date of Patent: June 25, 2013Assignee: Johns MansvilleInventors: Duane Paradis, Christopher J Griffin, Raymond C Swann, Joel Evan Hazy, Brad C Burdic
