  • Publication number: 20190174597
    Abstract: Systems and methods for maintaining the illumination intensity of one or more LEDs above a minimal intensity level. The systems and methods may include: (1) a current regulator for regulating the current in a circuit; (2) a voltage source for applying current to a circuit; (3) an LED with a minimal intensity level that correlates to a set-point temperature; and (4) a thermal sensor that is in proximity to the LED and adapted to sense a temperature proximal to the LED. The thermal sensor may transmit a signal to the current regulator if the sensed temperature exceeds the set-point temperature. Thereafter, the current regulator may take steps to regulate the current in order to maintain the LED illumination intensity above the minimal intensity level.

  • Patent number: 7067995
    Abstract: Method and system are disclosed for compensating for color variations due to thermal differences in LED based lighting systems. The method and system involves characterizing the LEDs to determine what PWM (pulse-width modulation) is needed at various operating temperatures to achieve a desired resultant color. The characterization data is then stored in the microprocessor either in the form of a correction factor or as actual data. When an operating temperature that is different from a calibration temperature is detected, the characterization data is used to adjust the PWM of the LEDs to restore the LEDs to the desired resultant color.

  • Patent number: 5061176
    Abstract: An apparatus and process for positioning and for simultaneously oscillating a plurality of heater probes within a plurality of heat exchanger tubes mounted in a tubesheet of a nuclear steam generator is disclosed herein. The apparatus generally comprises a frame, a plurality of probe drivers mounted onto the frame, wherein each driver includes a pneumatically operated, bladder-type gripper for selectively gripping and ungripping the push-cable of one of the heater probes, as well as an oscillating mechanism powered by a variable voltage d.c. motor. A controller connected between the d.c. motor and a power source separately controls the frequency and the amplitude of the cycle that the oscillating mechanism moves the gripper in, and further controls the alignment between the midpoint of the oscillatory cycle and a selected point along the longitudinal axis of the tube.

  • Patent number: 4829660
    Abstract: An improved system for removing a plug from the open end of a heat exchanger tube in a nuclear steam generator is disclosed herein. It is particularly adapted for removing a plug formed from an elongated, cylindrical shell of Inconel.RTM. having a closed end, an open ends, and an expander element that radially expands the shell when axially drawn from the clossed to the open end of the shell. The system comprises an expander remover for axially pushing the expander element from the open end completely through the closed end of the plug shell, and a TIG torch for creating beads along the longitudinal axis of the plug shell which relax the engagement between the plug shell and the tube after the weld beams harden. Finally, the system includes a plug puller for pulling the loosened plug from the tube.

  • Patent number: 4649609
    Abstract: Both an apparatus and process for providing a coolant flow path in the top former plate of the core of a nuclear reactor are disclosed. The apparatus of the invention generally comprises an elongated tool support member having a tool mounting means for detachably mounting various tools in the vicinity of the top former plate, and a clamp assembly for securing and positioning the tool mounting means over the plate. The apparatus also includes an ultrasonic transducer (or probe) for measuring the thickness of the plate, a rotabroach device having a feed and drive assembly for driving a pilot drill bit and a rotabroach bit toward the top former plate, and a piercing tool for removing the slug formed by the rotabroach bit. In the process of the invention, an alternate coolant flow path is provided in the top former plate by boring a plurality of holes therethrough.
