摘要： A powder feed nozzle for laser welding applications including a multiple outlet nozzle tip for focusing a discharged powder stream. The multiple outlet nozzle tip disperses multiple outlet streams and includes a powder discharge outlet and at least one focus gas discharge outlet, radially spaced from the powder discharge outlet, for dispersing a powder stream and a gas stream. Powder flows from a powder source through a powder channel to discharge a powder stream. Focus gas flows through a focus gas channel angled relative to the powder channel to discharge a focus gas stream.

摘要： In making a quick connection and hermetic seal for coupling low pressure systems of a type such as heat pipes and the like, a pre-installed fitting forming the sealing portion of a quick connection assembly is disposed in a depression formed in the sidewall of the low pressure chamber so that the chamber and the sealing portion of the connecting assembly can be fully processed together. The open end of a second system is coupled into the inserted sealing fitting by means of threads formed about a pipe plug device and carried by the tubular end portion of the second system.Sealant applied between the threads of the plug and fitting so that as the plug advances along the fitting a gas-tight seal will be obtained. The fitting includes a sealing membrane disposed across the inserted end thereof to be upset by advancing movement of the tubular end portion carried by the plug.

摘要： An online valve monitoring system senses operational characteristics of a valve and provides a diagnosis of aberrations in the characteristics. Sensors, coupled to a valve, supply sensor signals as output to a data acquisition system to be transmitted to a remote location. An I/O processor at the remote location receives the sensor signals and a diagnostic processor extracts characteristic features from the sensor signals as deviations from baseline data for the valve. An expert system applies a rule base to the characteristic features individually or in combination to diagnose the causes of the deviations. Use of multiple sensors increases the confidence of the diagnosis which can be immediately communicated to an operator and used for scheduling maintenance of the valve. Use of this diagnosis and the trend line of historical data permits scheduling of preventive maintenance.
