| 20080221845 | APPARATUS AND METHODS FOR PERFORMING PROCESS SIMULATION USING A HYBRID MODEL - The invention provides an apparatus and methods for performing process simulation and structural analysis using a hybrid model. For example, a method of the invention automatically defines a hybrid solution domain by dividing a representation of a plastic component or mold cavity into two portions—a portion in which a simplified analysis may be conducted, and a portion in which a more complex analysis is required. The method may use as input any form of CAD data that describes the surface of a component or mold. Furthermore, the invention provides methods for simulating fluid flow within a mold cavity by automatically creating a hybrid solution domain, automatically discretizing the domain, and solving for the distribution of process variables within the solution domain. | 09-11-2008 |

| 20100326327 | ENVIRONMENTALLY-FRIENDLY CEMENTITIOUS ARTICLES, FORMULATIONS, METHODS OF MAKING AND USES - Described herein is a cementitious article and a method of making using a water-based manufacturing system that incorporates a closed-loop or partially closed loop water recycling system and an alkali removal process. The system, as such is environmentally friendly, saves resources, such as water and other raw materials, and reduces waste disposal. The system further provides for a cementitious article having a low alkali content. Articles prepared by one or more processes described herein have characteristics that include a low apparent density, high strength and high freeze-thaw performance as compared with an article of the same general formulation but made from a comparative manufacturing system that does not include an alkali removal process. Articles described herein are suitable for use as building products, such as siding, the underlayment panel, board, trim, fascia, roofing, decking, and fence. | 12-30-2010 |

| 20090146108 | Methods and Formulations for Producing Low Density Products - A method of preparing a low-density material and precursor for forming a low-density material is provided. An aqueous mixture of inorganic primary component and a blowing agent is formed, the mixture is dried and optionally ground to form an expandable precursor. Such a precursor is then fired with activation of the blowing agent being controlled such that it is activated within a predetermined optimal temperature range. Control of the blowing agent can be accomplished via a variety of means including appropriate distribution throughout the precursor, addition of a control agent into the precursor, or modification of the firing conditions such as oxygen deficient or fuel rich environment, plasma heating etc. | 06-11-2009 |
| 20090156385 | Manufacture and use of engineered carbide and nitride composites - Carbides and nitrides are provided containing a controlled amount of pre-determined diluents and methods for their manufacture and use are disclosed. The pre-determined diluents include at least one of the silica, silicon metal, carbon, alumina, boron oxide, alkaline earth oxides such as calcium oxide, magnesium oxide, alkali oxides such as sodium oxide, potassium oxide, iron oxide, titanium oxide, and other components typically present in glass, ceramics, or metals. The carbides and nitrides with pre-determined diluents are formed by optionally pyrolyzing a precursor material to form a carboneous mixture and heat treating the carboneous mixture for a pre-determined time and at an elevated temperature during which carbon and/or nitrogen reacts with silica in the mixture to form carbides and/or nitrides and controlled amounts of pre-determined diluents. The carbides and nitrides disclosed herein may be used as blowing agents in a glass, ceramic, or metal forming processes or for promoting dispersion of the carbides and nitrides throughout a glass, ceramic, or metal composite. | 06-18-2009 |
| 20100192808 | Synthetic Microspheres and Methods of Making Same - A building product incorporating synthetic microspheres having a low alkali metal oxide content is provided. The synthetic microspheres are substantially chemically inert and thus a suitable replacement for natural cenospheres, particularly in caustic environments such as cementitious mixtures. The building product can have a cementitious matrix such as a fiber cement product. The synthetic microspheres can be incorporated as a low density additive and/or a filler for the building product and/or the like. | 08-05-2010 |
