Title: Barrier post assembly
Inventor: HART KENNETH
IPC: E01F15/04
Filed: 1992-05-02
Abstract: A barrier post assembly for a crash barrier system, for mounting on the floor of, e.g. a hospital area, comprises a post (1) and a base plate (2) for supporting the post in an upright position. A metal perimeter frame (4) is positioned around the post at a distance above the base plate to leave a gap between the post and the frame which is filled with an elastomeric material (E). During installation of the assembly, the perimeter frame is bedded on a concrete screed formed around the lower part of the post between the base plate and the elastomeric material, with a compressible filler material (8), such as expanded polystyrene, intermediate the screed and the said lower part of the post. By reason of the bond which is formed between the elastomeric material and the post and the frame, any impact applied to the post is absorbed in the elastomeric material and the compressible filler thereby to prevent the concrete screed from fracturing. <IMAGE>

Title: Boiler with low NOX combustion of gaseous fuels
Inventor: BRADY ROBERT THOMAS
IPC: F23C9/00
Filed: 1992-08-20
Abstract: Flue gas recirculation (FGR) provides low NOX combustion of natural gas in a compact steam boiler 2 having output steam delivery controlled by predetermined outlet steam pressure. The compact boiler employs a small high heat release combustor 30 discharging into a forced draft convective heat exchange section 5. The compact boiler is automatically self-operating, wherein the FGR is admitted into the burner combustion air through a valve 24 controlled by boiler flue gas NOX content. A bell mouthed flue gas scoop 22 is utilized in the boiler stack upstream of the NOX sensor (28, fig 1). in an alternative combustion chamber design, a cylindrical water wall coil 38 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. A further variation in the combustion system utilizes a ceramic shield (56, 58, fig 4) surrounding a natural gas burner as it fires into the compact combustion chamber. Primary and secondary combustion air are admitted to the combustion chamber through first stage combustion inside the shell and second stage combustion occurring in the boiler combustion chamber. <IMAGE>
