    • A method and apparatus for managing power demand of a motor in a cyclic load system having a rotational mass is provided. Flat power draw is achieved through continuous manipulation of the motor torque as a function of feedback velocity while using the rotational mass of the cyclic load as a means to store/retrieve energy. Alternatively, reduced variation of power draw is accomplished through continuous manipulation of motor velocity as a function of feedback torque. The methods and apparatus are used in systems where zero or reduced power demand variation is either required or desired, such as in generator powered applications.

    • An improved hydroformylation process involving reacting one or more reactants, such as an olefin, with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst, to produce a reaction product fluid comprising one or more products, preferably aldehydes; wherein said process is conducted in a region of the hydroformylation rate curve that is negative or inverse order in carbon monoxide, which is sufficient to prevent and/or lessen deactivation of the hydroformylation catalyst; and wherein total pressure is controlled at a predetermined target value and/or vent flow rate is controlled at a predetermined target value, by adjusting a flow of a carbon-monoxide containing inlet gas, so as to prevent and/or lessen cycling of process parameters, e.g., reaction rate, total pressure, vent flow rate, and/or temperature.

    • Systems and methods are described that carry out an intelligent, variable, time-gain control (TGC) of signal amplification in a long-range, guided-wave inspection and monitoring system. The systems and methods compensate for signal attenuation over the longer distances that guided-wave inspection techniques are capable of operating with. The sensor signal received is divided into relevant frequency bands that are each subjected to a variable TGC through separate variable gain amplifiers (VGAs). The gain selection is processor controlled through the use of a digital look-up table (LUT) stored with predetermined gain functions and/or data that are both time and frequency specific. The signal components are re-combined and digitized for further signal analysis and defect detection. The LUT is established through one or more methods including a weld signal amplitude equalization approach and a background noise equalization approach.
