Abstract: A graph-based clinical concept mapping algorithm maps ICD-9 (International Classification of Disease, Revision 9) and ICD-10 (International Classification of Disease, Revision 10) codes to unified Systematized Nomenclature of Medicine (SNOMED) clinical concepts to normalize longitudinal healthcare data to thereby improve tracking and the use of such data for research and commercial purposes. The graph-based clinical concept mapping algorithm advantageously combines a novel graph-based search algorithm and natural language processing to map orphan ICD codes (those without equivalents across codebases) by finding optimally relevant shared SNOMED concepts. The graph-based clinical concept mapping algorithm is further advantageously utilized to group ICD-9/10 codes into higher order, more prevalent SNOMED concepts to support clinical interpretation.

Abstract: A method for controlling emissions of a fossil fuel fired boiler including a high temperature fabric filter house with an SCR catalyst situated therein for receiving flue gases along with an injected ammoniacal compound and sorbent. The sorbent reacts with the SO.sub.x while the ammoniacal compound reduces the NO.sub.x in the presence of the SCR catalyst inside the high temperature fabric filter house. Both the SO.sub.x and the particulates are removed upstream of the SCR catalyst to diminish the problems of SO.sub.2 or SO.sub.3 poisoning of the catalyst and erosion and fouling of the catalyst with the fly ash. Since the sulfur oxides and particulates are removed prior to the heat recovery system, the fouling and corrosion potential are substantially decreased thus allowing the heat recovery system to be operated at a lower outlet flue gas temperature which yields an incremental improvement in energy recovery.

Abstract: A new and improved remotely controlled, day/night mirror apparatus includes an outer housing assembly for connection to an exterior portion of a motor vehicle. An inner housing support assembly is contained within the outer housing assembly and is supported by the outer housing assembly. An inner housing assembly is provided, and an adjustable connection assembly is connected between the inner housing assembly and the inner housing support assembly, for adjusting an angular orientation of the inner housing assembly with respect to the outer housing assembly. A day/night mirror assembly is pivotally supported by the inner housing assembly by a mirror pivot pin. An incremental tilt assembly is connected between the day/night mirror assembly and the inner housing assembly distal from the mirror pivot pin, for incrementally tilting the day/night mirror assembly around the mirror pivot pin from a day position to a night position and vice versa.

Abstract: An apparatus for controlling emissions of a coal fired boiler includes a hot catalytic baghouse for receiving flue gases along with injected ammonia and alkali. The alkali and ammonia react with SO.sub.x and NO.sub.x in the flue gas while particulates in the flue gas are trapped in the baghouse. The still hot but clean flue gases are supplied from the baghouse to a heat pipe air heater which also receives combustion air to be preheated before it is supplied to the boiler for combustion with coal to produce the flue gases.

Abstract: A process of controlling emission of SO.sub.x, NO.sub.x and particulates from a coal-fired boiler system is disclosed. A reagent/catalyst in powdered form is added into the combustion flue gas stream intermediate the boiler and economizer at a temperature below the melting point of the powder. The reagent/catalyst and ammonia are reacted with the SO.sub.x and NO.sub.x while the flue gas passes through the economizer. Further reaction is achieved as the gas is passed through the filter cake which forms on the filterhouse bags.

Abstract: A folding machine has a pair of longitudinally extending folding members which in a rest position shown in chain dotted outline have horizontal co-planar upper surfaces. A holding tool 41 holds a workpiece 42 on the folding members. To produce a fold or bend, the folding members are swung upwardly and outwardly about a common axis to form the workpiece around the holding tool. The adjacent edges of the folding members have interengaging projections and recesses so that the folding members overlap each other in the rest position.
