  • Patent number: 11473312
    Abstract: A corner trim material that is made of a material that will bond with current industry mastics such as all purpose joint compounds, resists impact, resists abrasion, and readily accepts common coatings such as drywall mud, texture and paints. The surface of this material generally does not need to be covered by any secondary fiber based material such as paper to improve bonding or coating on the inside or outside. The material generally consists of a polymer mixed with a fibrous material like pulp or glass fiber. A corner trim piece can be directly extruded from the mix. The corner trim piece can have a center hinge, can be bullnose, and the flanges can optionally have holes or optionally be coated with adhesive.

  • Publication number: 20030192251
    Abstract: A steam reformer that produces hydrogen gas from water and a carbon-containing feedstock, such as an alcohol or a hydrocarbon. The steam reformer includes a hydrogen-producing region, in which a mixed gas stream containing hydrogen gas and other gases is produced from water and a carbon-containing feedstock. The steam reformer includes a separation region, in which the mixed gas stream is separated into a hydrogen-rich stream containing at least substantially pure hydrogen gas, and a byproduct stream containing at least a substantial portion of the other gases. In some embodiments, the steam reformer is a vertically oriented fuel processor. In some embodiments, the separation region includes at least one hydrogen-selective membrane. In some embodiments, the steam reformer further includes a polishing region, in which the hydrogen-rich stream produced in the separation region is further purified. In some embodiments, the reformer includes an external metal or sealed ceramic shell.
