  • Patent number: 6699575
    Abstract: A wood sheathing panel, suitable for use in building construction, includes reinforcement strips of fiber reinforced polymer material incorporated into the panel. The reinforcement strips cover an area that is within the range of from about 5 to about 50 percent of the surface area of the panel. The reinforcement strips of fiber reinforced plastic material can be incorporated in the perimeter of the panel, or can be incorporated into the corners of the panel. The spacing of the intermittently incorporated reinforcement strips can generally coincide with a standard spacing of framing members so that when the wood sheathing panel is applied to a building frame, the reinforcement strips are generally aligned with framing members of the building. Preferably, the reinforcement strips are sufficient to provide an increased ductility over an equivalent unreinforced wood sheathing panel in an amount within the range of from about 75 percent to about 500 percent.

  • Patent number: 6699578
    Abstract: Composite film structures exhibit a predetermined finished color tone comprised of a transparent film layer which exhibits a color deficiency as compared to the finished color tone, and a pigment which is visually associated with, and satisfies the color deficiency of, the film layer. Most preferably, the pigment is provided as a homogenous dispersion in a transparent color-matching layer positioned adjacent to the film layer. Thus, when the film and color-matching layers are viewed collectively as a unit, the perceived color tone will be that of the finished predetermined color tone. That is, the color-matching layer provides visually an additive effect on the perceived color of the composite film structure.

  • Patent number: 6699579
    Abstract: We make particulates, especially magnetic Fe—Co alloys having high magnetic permeability, of controlled dimensions, especially those having a narrow thickness size distribution centered around a median or target thickness in the range of about 0.1-1.0 &mgr;m, using electrodeposition typically on a smooth (polished) titanium cathode. Our preferred continuous process uses a rotating drum cathode inside a fixed anode to grow flakes and to produce them automatically by inherent instability in the deposited film. The drum preferably rotates about a substantially vertical axis. The particulates shed (slough off) into the electrolyte (because of mismatch between the cathode surface and the plated metal or alloy at the molecular level) where they are separated in a magnetic separator or other suitable device. If the flakes are soft iron or iron-cobalt alloys, the drum generally is titanium or titanium alloy.

    Abstract: A coating composition (24) for a thermal/environmental barrier coating (T/EBC) system (14) particularly suited for protecting silicon-containing substrates (12), such as articles exposed to high temperatures including the hostile thermal environment of a gas turbine engine. The coating composition (24) is an alkaline earth aluminate or an alkaline earth aluminosilicate containing, by molar percent, about 20% to about 40% barium oxide, about 9% to about 20% strontia, about 19% to about 50% alumina, and optionally up to about 40% silica, wherein barium oxide and strontia are present in a combined amount of about 37 to about 50 molar percent of the coating composition (24). The T/EBC system (14) may include one or more intermediate layers (16,20,22) that adhere the coating composition (24) to the silicon-containing surface (12). The T/EBC system (14) may further include an outermost coating (18) of stabilized zirconia or another high-temperature ceramic material.

  • Patent number: 6699609
    Abstract: A fuel cell system includes a fuel cell in which a first reactant gas and a second reactant gas are supplied to generate electricity. An evaporator evaporates a raw fuel, which combustor exhaust gas discharged from the fuel cell and uses the exhaust gas to evaporate and volatile a raw material for the first reactant gas. A reformer reforms the evaporated and volatilized raw fuel vapor of the raw material by a reforming catalyst to produce the first reactant gas. An air-introducing device introduces the air that is used to be reformed into the evaporator or the reformed in a manner wherein the flow rate of the air is controlled depending upon the output from the fuel cell and upon the temperature of the raw fuel vapor.

  • Patent number: 6699611
    Abstract: A thermo-responsive polymer is incorporated into a fuel cell (50) in order to maintain optimum hydration of the polymer electrolyte membrane. The thermo-responsive polymer (52) is situated proximate to the membrane electrode assembly (54) such that fuel or oxidant gas passes (56) through the thermo-responsive polymer to the membrane electrode assembly. The thermo-responsive polymer swells or shrinks in response to changes in the operating temperature of the membrane electrode assembly, altering the flow rate of the fuel or oxidant gas passing through the thermo-responsive polymer.

  • Patent number: 6699612
    Abstract: The invention reduces free water volume in a fuel cell power plant so support systems of the plant are freeze tolerant. The fuel cell power plant includes a coolant system having a sealed cooler plate that circulates an antifreeze coolant in heat exchange with a fuel cell and that collects fuel cell water; a water vapor removal system that removes water vapor from the antifreeze coolant to regulate the antifreeze concentration; and a start-up system having a start-up heat exchanger and a start-up valve that selectively direct heated antifreeze coolant into the cooler plate for a start-up procedure. The plant may also include a fuel processing system that utilizes the removed water vapor, and that is in heat exchange with the start-up heat exchanger. The antifreeze coolant is a low vapor pressure solution, such as an alkanetriol or polyethylene glycol.
