Abstract: A conferencing assembly, the assembly comprising a support, at least one table top member forming a substantially flat top surface, the at least one top member supported by the support with the flat surface substantially horizontal, the at least one top member including at least first and second substantially straight edge sections where the second edge section forms an angle with respect to the first edge section of less than substantially sixty degrees and at least first and second display screens positioned adjacent and substantially parallel to the first and second edge sections, respectively, each of the first and second display screens facing across at least a portion of the top surface of the top member.

Abstract: A method and apparatus for low NOX combustion of natural gas in a compact steam boiler having output steam delivery controlled by predetermined outlet steam pressure. The compact boiler employs a small high heat release combustor discharging into a forced draft convective heat exchange section. In operation, the compact boiler is completely and automatically self-operating, employing flue gas recirculation (FGR) wherein the FGR is admitted into the burner combustion air through a valve controlled by boiler flue gas NOX content. A novel bell mouthed flue gas scoop is utilized in the boiler stack upstream of the NOX sensor. In an alternate combustion chamber design, a cylindrical water wall coil surrounds the combustion process, increasing boiler efficiency through the inherent large temperature difference between the coil and the combustion in process, along with reducing the combustion temperature and further reducing the NOX content of combustion products.
