摘要： The present invention provides for steam generation replacing natural gas with a selected refined product of a feedstock of bitumen, asphaltines or heavy oil using locally produced surplus bitumen, asphaltine or heavy oil, separating the asphaltines and other components of the feedstock for use in providing a liquid fuel for steam generation. The lighter products from the separation equipment not used for liquid fuel may be blended into the produced bitumen, asphaltines or heavy oil, to increase its API gravity and reduce the diluent required for transportation. This technology may be employed in open pit mining operations for the generation of steam and power. The refined components of the feedstock used to provide liquid fuel are selected to optimize energy output balancing planned energy demand against the value of the components of the feedstock used.

摘要： Chopper circuitry may be adapted to operate in a high-temperature environment of a turbine. A first semiconductor switch (122) may have a first terminal coupled to receive a first output signal from a first leg (148) of a differential amplifier (150). A second switch (128) may have a first terminal coupled thru a first resistive element (R1) to a second terminal of the first semiconductor switch. The first terminal of the second semiconductor switch may be coupled to receive thru a second resistive element (R2) a second output signal from a second leg (152) of the amplifier. Switches (122,128) may be responsive to a switching control signal to respective gate terminals of the switches to supply an output signal, which alternates in correspondence with a frequency of the switching control signal from a first amplitude level to a second amplitude level, which effectively provides a doubling amplification factor.

摘要： A telemetry system for use in a combustion turbine engine (10) that includes a first sensor (306) in connection with a turbine blade (301) or vane (22). A first telemetry transmitter circuit (312) is affixed to the turbine blade and routes electronic data signals, indicative of a condition of the blade, from the sensor to a rotating data antenna (314) that is affixed to the turbine blade or is on a same substrate as that of the circuit. A stationary data antenna (333) may be affixed to a stationary component (323) proximate and in spaced relation to the rotating data antenna for receiving electronic data signals from the rotating data antenna. A second sensor (335) transmits electronic data signals indicative of the stationary component to a second telemetry circuit (332), which routes the signals to the stationary antenna.

The catalyst is deactivated by sequentially admixing therewith a minor amount of a nitrogenous base, especially an aqueous solution of such a base, followed by a solution of a salt of an alkaline earth metal or zinc and an aliphatic monocarboxylic acid dissolved in hydrocarbon solvent. The ratio of water:nitrogenous base should not be greater than 5. The hydrocarbon solvent and other volatile matter are then separated from the resultant solution and a composition comprising said high molecular weight polymer is recovered. The amount of nitrogenous base plus any water is not more than 2.5 moles per mole of halogen plus alkyl radicals in the coordination catalyst.
