    Abstract: The present invention is directed to a method and a system for fault detection analysis in a power device which is operatively associated with a differential protection unit. The power device has one input side and one output side through which an input current and an output current flows into and out from it, respectively. Signals representative of the input and output currents are processed in order to verify if an occurring fault is external to the power device. Under a condition of an external fault, the differential protection unit is disabled for a determined interval of time.

    Abstract: A polymer reaction and quality optimizer that optimally determines all factors affecting the finished polymer prior to initiating the batch, uses the optimized parameters in setting up and starting the batch, in an on-line procedure for correcting assumptions made in the optimal determination based upon measurement responses from batch startup, and in an on-line procedure that periodically executes to determine and adapt reactor temperature control profiles across the remaining life of the batch to achieve the desired polymer properties and optimal polymer yield. The reaction and quality optimizer also determines at the end of a batch using several criteria if any of the equipment used within the process such as the reactor should be cleaned.

    Abstract: A signal processing technique that allows the flame signal from a first source of flame and the flame signal from a second source of flame to be discriminated from each other when only both the first and second flame signals are viewed by the same flame scanner. The signal from the flame scanner is processed to enhance one or more of the attributes associated with the first flame and is simultaneously processed to enhance one or more attributes associated with the second flame.

    Abstract: A system for use in ac to ac or dc to ac power conversion equipment to detect faults in an inverter when the inverter (18) is in a high impedance mode. The system detects ground faults or cross wiring conditions by converting the inverter outputs to digital signals and evaluating the frequencies of the resulting signals. The system keeps the inverter in the high impedance mode until after it has been determined that neither of the described abnormal statuses exist. The system tests for both of the abnormal statuses on power up and thereafter tests only for a ground fault whenever the inverter switches are disabled.

    Abstract: A control system for a centrifuge that allows the centrifuge to continue to run when there is a short duration failure or outage of the AC power source. The control system allows the centrifuge to be brought to a stop in a normal shutdown mode where there are longer duration failures or outages of the AC power source. This allows power to be maintained to the pump that lubricates the centrifuge bearings so that the bearings are lubricated during the coast down of the centrifuge and the differential speed of the centrifuge to be controlled during coast down allowing the centrifuge bowl to be cleared of solids so that the centrifuge can be immediately started up at lower vibration levels once power is restored.

    Abstract: An intelligent automatic bypass for a motor control device determines if a fault that is occurring in the motor control device is a restricted or non-restricted fault. A restricted fault is one that may damage or destroy the motor if an automatic switch to bypass is allowed to occur for all faults that occur in the motor control device. The intelligent automatic bypass allows the automatic switch to bypass only if the fault is a non-restricted fault and blocks the automatic switch to bypass if the fault is a restricted fault.

    Abstract: There is described a method and apparatus for controlling the combustion by-product formation rate in at least one burner of a fossil fuel fired power plant. The burner has an associated flame scanner which is focused on a small area of the burner flame to obtain an image signal of the flame. A flame signal that represents properties of temporal combustion in the visible light spectrum of the burner is generated from the image signal. Combustion turbulence at the burner is analyzed from the flame signal by a dynamic invariant that has a relationship to the combustion by-product values and different combustion by-product levels at the burner and the combustion turbulence is correlated to the combustion by-product formation rate at the burner.The method and apparatus can also be used to correlated the combustion turbulence at a multiplicity of burners to the associated combustion by-product formation rate.
