Abstract: A mounting device includes a base having a first major surface and a second opposite major surface; a supporting member having a supporting surface connected to the base, and spaced from and facing away from the base, and an engaging member having an engaging surface in facing relationship to the supporting surface. The engaging member is connected to the base and the supporting member such that moving the supporting member toward the base moves the engaging member toward the base. A biasing force, e.g. a spring or movement of the supporting member, biases the engaging surface toward the supporting surface. The mounting devices can be mounted on a surface of a substrate, e.g. an automotive transparency, to provide a panel, and the panels can be fixedly secured over an opening, e.g. an opening the body of a vehicle, without the use of structural adhesive.

Abstract: Light weight structural wall panels are made of two layers of load bearing skins, separated by a light-weight concrete, using expanded materials such as Perlite, Pulverized Fuel Ash, Styrene or foam cement to form a sandwiched construction for structural strength. The load-bearing skins, which are sprayed into a mold, are made of glass fiber, sand and cement matrix in different thickness and mix ratios. All edges of the encapsulated panels are made of the same GFRC matrix. The distance between GFRC inner & outer layers dictates the required structural strength of overall finished panel to resist wind & earthquake loadings. The sprayed layers and the core are made/cast while the concrete is green, before its initial setting-time to ensure structural integrity of components after curing.

Abstract: As shown schematically in FIG. 1, hot gases, containing molecular oxygen, from generator elements, (14) and (19), pass through a bed of coal chunks in an ODD reactor chamber (2). The molecular oxygen content of these hot gases is less than stoichiometric, relative to the coal volatile matter content, so that partial oxidation of only the volatile matter occurs within the ODD reactor chamber, (2), during devolatilization therein. Two products are thusly created, a partially oxidized, and hence cleaner burning, volatile matter fuel gas, and a solid devolatilized coke. The hot coke is transferred, by overfeed, into a coke reaction chamber, (7), where counterflowing primary air, via air meter, (12), gasifies the coke into carbon monoxide with some carbon dioxide. Finally, the carbon monoxide and the partially oxidized volatile matter, are admixed with overfire air, and burned fully to carbon dioxide in overfire burner chambers, (23), (26).

Abstract: In an exhaust aftertreatment system comprising a NOx adsorber-catalyst followed by an SCR catalyst, means are provided for preventing the SCR catalyst from becoming heated to near the same peak temperatures as the NOx adsorber-catalyst during desulfation. In one embodiment, the means is a thermal mass between the NOx adsorber-catalyst and the SCR catalyst.

The temperature peaks are damped as they travel from the NOx adsorber-catalyst to the SCR, whereby the SCR experiences much lower peak temperatures than the NOx adsorber-catalyst.

Abstract: A power generation system comprising a LNT for exhaust aftertreatment. The LNT has an effective operating temperature range. When the LNT is near a limit of its effective operating temperature range, the transmission is used to select operating points that increase the LNT's effectiveness. Generally, these operating points reduce the exhaust flow rate, although other factors such as the exhaust temperature may also be taken into account in selecting the operating points. Preferably, the LNT's effective operating temperature-range includes exhaust temperatures produced by the engine at its point of peak power output, whereby the LNT does not approach the limits of its effective operating temperature range except when the engine is at less than peak power. At lower power levels, it is generally possible to select operating points that provide lower exhaust flow rates than the flow rate occurring at the peak power level.
