摘要： A system for implementing accurate V/Hz value measurement and trip time determination for generator/transformer overexcitation protection independent of the conventional frequency tracking and phasor estimation based on Discrete Fourier Transformation (DFT) techniques. A sampled sinusoidal voltage signal is passed through a digital integrator and the magnitude of the digital integrator's output is measured as representative of the V/Hz ratio. The digital integrator is implemented in software using a difference equation in a generator protection unit. The technique may be used with either a fixed or a variable sampling frequency. When the sampling frequency is variable, the filter coefficients of the digital integrator are recalculated on-line each time the sampling frequency is changed, and a new value for the peak magnitude of the output of the digital integrator is calculated using the recalculated filter coefficients. Non-linear frequency response characteristics of the voltage sensors and non-ideal characteristics of the digital integrator are also adjusted using the measured frequency and error-frequency characteristics of the particular digital integrator and voltage sensors used.

摘要： An improved technique for the active control of various combustion devices. This improved technique employs a flame kernel pulse actuator which produces periodic flame kernels by a spark ignition of a stoichiometric air and fuel mixture upstream of the combustion chamber. The discrete flame kernels are convected in a duct of premixed fuel and air which produce discrete pressure oscillations due to the energy release as each discrete flame propagates. Because the source of the energy release is essentially a chemical reaction, the flame kernel pulse actuator is able to produce a substantial amount of energy release even at the high operating pressures which are often encountered in many operational environments. These pressure oscillations may be adjusted to suppress or augment any combustion induced pressure oscillations as well as act to modulate the mixing layer between the fuel and air, thus controlling the downstream combustion process.The flame kernel pulse actuator comprises an actuator housing, a secondary fuel injection system, and an igniter. The combination of the igniter and fuel injection system produces a plurality of discrete flame kernels which are convected downstream toward the combustion chamber. The present flame kernel pulse actuator further includes a pressure sensor which is positioned so as to measure the acoustic oscillations in the combustion chamber and a controller device which uses the output of the sensor to control the frequency, phase shift, and amplitude of the discrete flame kernels.

摘要： A domestic refrigerator control arrangement for automatically defrosting the cabinet with a minimum of cycle time while obviating the buildup of frost within the cold air conduits. A defrost heater is located at the frontal area of the evaporator coils and the defrost thermostat on the rearward edge of the cross fins coil assembly in the air stream of the air circulating fan sensing the temperature of the air exiting the evaporator. The fan is wired in series with the defrost thermostat and operates upon the energization of the defrost heater, while being deenergized upon the opening of the defrost thermostat contacts at the end of the defrost period. The fan remains in its off position until the defrost thermostat recloses, insuring that moisture-laden air is not distributed throughout the refrigerator.
