Daniel V. Hanson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7728096
    Abstract: The present invention is an adhesive suitable for use in the production of engineered wood products, said adhesive comprised of an aromatic diisocyanate (99.0-10.0 parts by mass) and an aromatic petroleum distillate (1.0-90.0 parts by mass) with low volatility. The adhesive composition may result in improved coverage or distribution on the outer surface of raw materials, such as strands, particles, flakes, fibers, or veneer.
    Type: Grant

  • Patent number: 7726085
    Abstract: Systems for attaching a plurality of wood products are provided. In a first type of system, a first wood product has a first chemical compound applied to a surface of the first wood product. A second wood product has a second chemical compound applied to a surface of the second wood product. An adduct is formed when the first chemical compound contacts the second chemical compound wherein the first wood product becomes adhered to the second wood product. In a second type of system, a pressure sensitive and/or anaerobic adhesive is placed on at least one of the wood products prior to assembly. The compounds/adhesives have an open assembly time greater than or approximately equal to 24 hours.

  • Patent number: 7279226
    Abstract: A composition and method for inhibiting stain formation in a floor covering. The composition includes a copper glycine complex in combination with magnesium hydroxide and a carrier. The composition can be advantageously applied to a wood-based substrate upon which a floor covering is overlaid. Flooring assemblies that include the composition are also provided.

  • Patent number: 7141195
    Abstract: A process for making engineered lignocellulosic-based panels with superior strength and dimensional stability. The process comprising adding to green lignocellulosic particles a low-nitrogen content, high molecular weight, phenol-formaldehyde resin before the green particles are dried. The resin is added in an amount from about 1 to 25 weight percent based on the dry weight of the green lignocellulosic particles. The resin has a nitrogen content of from about 0 to 3%, a viscosity of from about 20 to 2000 cps at 20° C., and a molar ratio of formaldehyde/phenol of from about 1.2 to 3.0. The green lignocellulosic particles treated with the resin are dried until the particles have a moisture content of from 1 to 8%. A second resin is added to the dried particles and then the dried particles are consolidated under heat and pressure to form the engineered panel.

  • Patent number: 6489037
    Abstract: A coating that inhibits stain formation in floor covering. The coating includes a copper amine complex, preferably a copper morpholine complex, and is advantageously applied to an underlayment upon which a floor covering is adhered. Coated panels and floor assemblies that include the coating are also described.
