  • Patent number: 8945678
    Abstract: An article of manufacture and a method of manufacturing a soft batt insulation material. The article of manufacture comprises fibers having crimps and surface features such as scales that provide a batt structure which is resiliently compressible. Fiber treatments provide fire, pest, fungus, and mold resistance. The treatments can be to the surface or to the internal structure of the fiber. The insulation batts are comprised of one or more layers of intermeshed fibers. The fibers can be wool or other protein based hair. The batts can include a restrainment structure that limits that expansion of the batts.

    Abstract: Wood products, specifically wood commonly used in construction including dimension lumber, pressure treated pine, composite wood materials such as plywood, particle board, and wafer board, and samples of paper and fabric were variously treated with concentrations of sodium silicate (Na2O.SiO2) also known as water glass. Cellulosic materials including dimension lumber, plywood, particle board, wafer board, paper, and fabric were treated with sodium silicate (Na2O.SiO2) in concentrations ranging from 400-0.04 g Na2O.SiO2/kg water. To overcome the disadvantages of sodium silicate, sodium silicate treated samples were further treated to convert the water soluble sodium silicate to a water insoluble form, thereby overcoming the disadvantages of water solubility, and rendering the material effective for internal and external uses.

  • Publication number: 20090117285
    Abstract: Provided is an electroless iron bath capable of depositing a ferromagnetic FeB coating onto Pd/Sn-catalyzed substrates at room temperature without the need for an accompanying galvanic couple. The new electroless iron bath is comprised of Fe2+ as the metal source, citrate as the metal chelator, boric acid buffer as the pH controller, and borohydride as the reductant. Surface analysis following plating confirms the deposition of an amorphous FeB coating onto the surface of Pd/Sn-catalyzed cellulose microfibers.

  • Patent number: 7297411
    Abstract: Wood products, specifically wood commonly used in construction including dimension lumber, pressure treated pine, composite wood materials such as plywood, particle board, and wafer board, and samples of paper and fabric were variously treated with concentrations of sodium silicate (Na2OSiO2) also known as water glass. Cellulosic materials including dimension lumber, plywood, particle board, wafer board, paper, and fabric were treated with sodium silicate (Na2O.SiO2) in concentrations ranging from 400-0.04 g Na2O.SiO2/kg water. To overcome the disadvantages of sodium silicate, sodium silicate treated samples were further treated to convert the water soluble sodium silicate to a water insoluble form, thereby overcoming the disadvantages of water solubility. and rendering the material effective for internal and external uses.

  • Patent number: 7288146
    Abstract: A coated titanium dioxide pigment with good opacity and simultaneously good retention for use in decorative laminating paper characterized by a surface coating containing aluminum oxide phosphate and attached hollow bodies, e.g., hollow microbodies. A manufacturing method is characterized in that an aluminum containing component and a phosphorus containing component are first added to a TiO2 suspension, during which time the pH value does not drop below 10. The hollow bodies are subsequently added, followed by addition of at least one acidic component, as a result of which the pH value of the suspension is lowered to the range from about 4 to 9. In an alternative embodiment of the method, the suspension has a pH value of under 4 at the time of addition of the aluminum containing component and a phosphorus containing component.

  • Patent number: 7160606
    Abstract: A method of treating building materials with boron and boron treated building materials. The method involves introducing boron during manufacture of the building materials in the form of a water soluble copper-borate complex. The copper-borate complex enables a wider range of glues and adhesives to be used, is slower to leach out, and provides enhanced fungicidal properties.

  • Patent number: RE40517
    Abstract: Materials variously treated with sodium silicate were studied until enough information was obtained to find a way to solve the problems that have prevented sodium silicate from being the used as a fire retardant. These problems are: 1) water solubility (miscible with water), which results in extensive leaching when exposed to water, 2) cracking, chipping and peeling of treated surfaces, and 3) surface granulation. During flame tests it was discovered that sodium silicate formed a foam-like material, and this material was found to have become water insoluble, yet its elemental composition had remained virtually identical to that of the unmodified sodium silicate. This investigator proposes that under the influence of heat and dehydration, sodium silicate undergoes a polymerization process resulting in particles sizes too large to dissolve in water, and then developed a mechanism to explain how the process could occur.
