Abstract: Procédé permettant de détecter une prédisposition à l'asthme chez une personne. La personne inhale une dose efficace de chlorure de sodium, de mannitol ou de toute autre substance susceptible de modifier l'osmolarité d'un liquide de surface des voies aériennes chez le sujet. La substance se présente sous forme d'une poudre sèche dispersible contenant une proportion efficace de particules de taille respirable. On effectue ensuite des mesures en vue de détecter un rétrécissement des voies aériennes du sujet, ce qui indiquerait une prédisposition à l'asthme. La même technique d'inhalation d'une poudre sèche peut être utilisée pour détecter une prédisposition aux rhinites chez une personne, pour induire la production de salive et favoriser la clairance mucociliaire.

Abstract: An adapter for switching the fluid uptake port (P1) of a manually operated fluid-dispensing pump (P) between a plurality of fluid reservoirs. The adapter has an adapter outlet port (12) in fluid communication with the fluid uptake port (P1) and at least two adapter inlet ports (11). The adapter has concentric outer (13) and inner (16) housings. In a preferred embodiment, the outer housing (13) is affixed to a plurality of fluid reservoirs. The position of the outer housing (13), which is manually rotated with respect to the inner housing (16), is determined by a spring-loaded detent. Rotation of the outer housing (13) through successive detent stops sequentially connects the fluid uptake port (P1) of the fluid dispenser pump (P) with one of the adapter inlet ports (11) which are adapted to be in fluid communication with fluid reservoirs.

Abstract: Multilayer fluid conduits are formed by adhering to a tubular outer surface of a metal pipe, a thermoplastic outer layer. The outer layer permits ends of the multilayer conduit to be joined together in leak-proof fluid conduit systems simply by adhering the conduit ends with compatible thermoplastic fittings. For fire protection systems, the preferred metal is steel, the preferred thermoplastic is CPVC and the preferred adhesive is heat activated. The adhesive coated metal pipe is preheated and the CPVC is extruded onto the outer surface of the heated metal pipe. Through the use of fire resistive CPVC, the multilayer conduit systems of the present invention can be installed in more severe fire threat areas than can existing, all plastic piping, including all CPVC piping systems. The conduit is assembled into systems on site simply by cutting and direct bonding with ordinary, all plastic fittings using appropriate bonding agents such as solvent based adhesives. CPVC fittings are preferred for fire protection systems.

Abstract: The invention relates to a grate assembly for a fluidized bed boiler, a number of parallel sparge pipes extending substantially in horizontal direction and being provided with fluidizing air supply conduits for supplying fluidizing air from within the sparge pipes into a combustion chamber (T) located above the grate assembly. Coarse combustion material is discharged through an aperture system between the sparge pipes and into a receiver unit fitted below the grate assembly. At least some of the sparge pipes are provided with a cooling medium circulation system, wherein at least one coolant conduit of the cooling medium circulation system is placed within a surface of the sparge pipes at the upper edges thereof, to extend in a manner that it provides a limit to the edge of the aperture system in the upper part of the sparge pipe and in longitudinal direction of the sparge pipe. The fluidizing air supply conduits comprise a tubular air supply conduit that is directed upwardly away from the upper surface of the sparge pipe. The air supply conduit is provided with air nozzle apertures, in particular, at its upper end. The air supply conduit for at least some of the fluidizing air supply conduits is fitted in vertical direction to extend vertically above the coolant conduit of the cooling medium circulation system. This provides for an effective fluidizing air supply at the upper end of the aperture without the use of excessive air flow and pressure, thereby controlling operating cost.

Abstract: On décrit des catalyseurs améliorés consistant en un cyanure bimétallique (DMC), utiles pour fabriquer des polymères époxydes. Un catalyseur se compose d'une pâte d'un composé cyanure bimétallique (DMC), d'un complexant et d'eau. La pâte comprend au moins environ 90 % en poids de particules possédant une dimension de particule se situant dans la plage comprise entre environ 0,1 et environ 10 microns, telle que mesurée par diffusion lumineuse dans des dispersions, à base de polyol de polyéther, de particules de catalyseur. Des catalyseurs préférés présentent une distribution bimodale de dimension de particule. Ce catalyseur en pâte est plus actif et plus simple à préparer que les catalyseurs DMC en poudre. Des polyols fabriqués à partir de ce catalyseur en pâte sont faiblement insaturés et visqueux, présentent des répartitions étroites de poids moléculaires et sont utiles dans la fabrication d'une variété de produits en polyuréthane. On obtient également de meilleurs résultats avec des catalyseur DMC sous forme de poudre dont la dimension de particule est très petite.

Abstract: A method and apparatus for monitoring the quality of a laser process such as a welding process comprises monitoring the light emitted from the weld plasma above the surface of the workpiece being irradiated by the laser beam.  The size of the plasma is determined from the light emission and compared to a predetermined value of the size as determined under process and workpiece conditions that produce welds of acceptable quality.  Variations of the monitored plasma size greater than a preselected value can represent unacceptable welds.  Such variations can be caused by changes in the laser beam power, the workpiece speed, laser focusing problems, insufficient shield gas flow, workpiece deformation and weld contamination.  The process monitors the light emission from a selected range of wavelengths that correspond to the major emission peaks of the light spectrum.  The process enables in-process control.

Abstract: A tubular skylight having an improved dome improving the efficiency of the skylight and reducing the shadows cast by the skylight. The dome includes a substantially vertical rear face having an integral prism in a portion of its outer surface, and the rear face is offset inwardly from the perimeter of the reflective tube, thus allowing light to escape from the bottom edge of the rear face downwardly into the reflective tube. The integral prism does not extend to the top or front face of the dome, thus reducing the prevalence of shadows created by light rays entering the dome through the prism.

Granted: 2001-10-30
Abstract: An electrical control system preferably for vehicles such as a transit vehicle is arranged with a plurality of separate modules each receiving input from a series of inputs and each providing a series of outputs so that the modules combined receive inputs from all of the control, transducer and other input elements of the vehicle and the modules as a whole provide output to all of the controlled elements of the vehicle. The modules communicate between one another via a communication bus and an operational program is installed in each of the modules so that all modules contain programming for the functions of each module. A replacement module is generic and thus can contain any operational program and thus can be used for many different designs of the system. As supplied, the module may contain an existing program or no operational program if not yet programmed. On a subsequent power-up after installation of the replacement module, a check program is run to determine that a replacement module is in place and to download the operational program from a selected one of the existing modules into the replacement module. This allows service personnel to readily install replacement modules without the necessity for dedication of the modules to specific design schemes.
