    摘要: A digital nuclear reactor control rod position indication system employing a plurality of Hall Effect transducers longitudinally spaced along the control rod drive housing. The transducers are individually responsive to a magnetic field generated by a magnetized portion of the control drive rod to respectively provide an output when in substantial proximity to the magnetized rod portion. The transducer outputs are multiplexed to display the relative position of the control rods within the reactor core.

    摘要: A gas turbine power plant metal combustion chamber cylinder is lined on its inside with two layers of ceramic material. The radially innermost layer is an interlocking, tile-like structure of dense ceramic material providing good thermal shock resistance. The intermediate layer which is disposed between the metal cylinder and the innermost layer is a low density ceramic material providing high thermal insulation. The layers of ceramic material are supported by ceramic tubes extending from the outer metal cylinder of the combustor through the intermediate wall and the inner wall. The tubes are also used to direct cooling air into the combustion chamber and increase the turbulence of the burning fuel and air within the chamber.

    摘要: A method of constructing a magnetic core for electrical inductive apparatus, such as transformers and reactors, having stepped-lap joints between adjoining leg and yoke portions thereof. The method provides a continuous stepped-lap joint which extends around each corner of the magnetic core, while incrementally clipping only one end of each leg and yoke lamination, and the laminations are assembled without any portion thereof protruding past the major outline of the magnetic core configuration.

    摘要: In a liquid-cooled rotor for large dynamoelectric machines such as turbine generators, electrical connection to the rotor winding is made by longitudinal leads extending from the winding along the rotor shaft. These longitudinal leads are connected by radial leads to axial conductors extending through the bore of the shaft for connection to an exciter or other external source of excitation current. The longitudinal leads extending from the radial leads to the rotor winding are cooled by circulation of a coolant liquid such as water through passages in the leads, the coolant liquid being supplied from the same coolant distribution chamber which supplies liquid to the conductors of the rotor winding. The radial leads are preferably also cooled by circulation of the same coolant liquid which cools the longitudinal leads.

    摘要: A radioisotope imaging system wherein the position of an amplified scintillation is determined by optical coding means that is essentially insensitive to variations in the strength of the scintillation. This permits a more accurate position location and, therefore, a higher resolution in the final image. At the same time, sensitivity remains high, as does discrimination in energy.

    摘要: A method and apparatus for controlling the time constant of an integrator linearly as a function of a control voltage. A ramp signal having a negative slope proportional to the magnitude of the applied signal generates a pulse each time it decays to a predetermined level. An accumulated count of the pulses is transformed into an analog output signal by a digital-to-analog converter. Each time a pulse is generated the ramp signal is reset to a level determined by the control voltage, hence, the time constant of the integrator is a linear function of the magnitude of the control voltage.

    摘要: In a waveform generator such as a sawtooth wave generator, automatic slope calibration is provided. A variable resistance element is feedback-responsive and provides an input voltage which affects waveform shape. The shape of the waveform is controlled automatically by a time error signal through the use of a feedback loop which controls the input voltage. In one embodiment, the feedback loop measures the time at which waveform voltage reaches a predetermined level and compares the time span it takes for the value of the waveform to reach the predetermined level to a preselected time span to provide the time error signal. The time error signal is utilized in a closed loop to control the voltage supplied by the variable resistance element. In another embodiment, the feedback loop measures the voltage difference between a fixed reference and the generated waveform at a predetermined time to generate the time error signal and control the input voltage supplied from the variable resistance element.

The gas turbine is provided with a liquid fuel system having a turbine driven pump which supplies fuel to turbine nozzles through a throttle valve. A bypass pump pressure regulator valve and a bypass pressure temperature limiter valve function together to provide stable fuel pressure operation and stable turbine inlet air temperature operation during ignition and other turbine operating periods. Such bypass means are operated substantially independently of the control system.
