Abstract: A power generating system comprises a condenser and a deaerator apparatus. The condenser condenses a working fluid into a condensate and operates at an internal pressure above ambient pressure during a normal operating mode. The deaerator apparatus uses steam to remove contaminants from the condensate to bring the condensate to a desirable purity. The deaerator apparatus is deactivated during a typical operating state of the power generating system such that the condensate bypasses the deaerator apparatus. The deaerator apparatus is activated during a non-typical operating state of the power generating system such that the condensate passes into the deaerator apparatus wherein contaminants can be removed from the condensate. The typical operating state of the power generating system occurs when the condensate comprises a desirable purity and the non-typical operating state of the power generating system occurs when the condensate comprises an undesirable purity.

Abstract: Methods and apparatus for monitoring an arc welding process are disclosed. In a preferred embodiment, the present invention creates a digital representation of the arc created during welding and, using a neural network computer, determines if the arc is representative of normal or abnormal welding conditions. The neural network disclosed is trained to identify abnormal conditions and normal conditions and may be adaptively retrained to classify images that are not in the initial set of normal and abnormal images. In certain embodiments, other data, such as current, weld wire emission spectra, or shielding gas flow rate are also collected and the neural network is trained to monitor these data. Also, in certain embodiments, an audio signal is collected from the vicinity of the welding process and is used by the neural network computer to further classify the arc as normal or abnormal. The present invention is most preferably implemented in repetitive and continuous welding operations, such as those encountered in the manufacture and rebuilding of steam turbines.

Abstract: A method and apparatus for monitoring a plurality of processes which are identical with respect to at least one process parameter, employing a plurality of sensors each disposed for monitoring the one process parameter of a respective process, the sensors all having identical responses to the one process parameter. Monitoring is performed by: deriving (2-10) from the sensor responses a succession of response samples each derived from a respective sensor. Then each sample is monitored in succession and a predetermined characteristic of the sensor response represented by each sample is evaluated, the monitoring step being carried out in a processing path having an input to which all samples are supplied in series and providing an output indication of the evaluating result for each sample. Finally, the indication of the evaluating result of each sample is interpreted in order to provide an indication of the status of each process.

Abstract: The present invention provides constant fluid flow and constant pressure to chemical analysis monitors 24-26 for reliably monitoring the quality of fluid in a plant such as a power generating plant. A high pressure fluid source 28 provides fluid to a forward pressure regulating valve 30. The valve 30 supplies a metering valve 36 which regulates flow. The pressure on the output side of the metering valve 36 is maintained constant by a back-pressure regulating valve 40. The constant pressure and flow fluid is supplied from between valves 36 and 40. Excess fluid bled off by valve 40 can be returned to the source 28. A second stage of pressure regulation which improves pressure constancy can be provided by valves 45 and 46 at the first stage pressure or at a different pressure.

Abstract: Fluid flow is determined for a large flow pipe based upon differential pressure across an orifice in the pipe having a known cross-sectional area. In one form, the orifice is variable and adjusted in response to differential pressure so as to maintain differential pressure at a constant value. Flow is determined directly from orifice area. The orifice may be a part of a closed loop flow measurement system which responds to differential pressure changes to adjust orifice area. Various differential pressure settings may be used to accommodate selected back pressures in the flow pipe.
