摘要： A system for detecting and imaging gamma radiation emitted by a contaminated area includes a plurality of collimators spaced a distance apart from each other. The collimators have a plurality of holes therethrough and the holes of one collimator are aligned with the holes in another collimator for forming a plurality of hole alignments which permit gamma rays to pass through the collimators. A scintillator and operatively connected avalanche photodiode are provided with each aligned hole of the collimators for determining the position of the gamma ray which passes through the collimators. A video camera records a visual image of the contaminated area and a monitor displays the video image along with location and size information provided by the avalanche photodiodes.

摘要： A fiber optic loop temperature sensor employs a fiber optic loop (90) having a predetermined fixed radius where a light source (96) supplies light to the signal optical fiber (92) with the loop and a second reference optical fiber (100) receives light from the light source (96) for providing a reference light intensity. The light intensities from both optical fibers are measured and the temperature is determined from differences therein. Advantageously, the fiber optic loop temperature sensor is employed in a temperature compensated, self-referenced fiber optic microbend pressure transducer to compensate for thermal offset of the microbend sensor output. In the preferred embodiment, time division multiplexing provides at least two bi-cell photodetectors (82) with output and source signals for generating a log ratio output for determining the sensed parameter independent of cable and connector offsets and light source fluctuations in addition to compensation for thermal offset. An alternate embodiment uses time domain intensity referencing.

摘要： An apparatus and method for pacing the application of a manual weld along the weld line generates beeps or light flashes at a rate which can be correlated by the welder with markings along the weld line. As each beep or flash is perceived, the welder should reach the next marking. Spacing between the markings determines the desired rate at which the weld is being applied. Alternatively, sequentially lightable areas are distributed along the weld line and sequentially lit a desired rate. The welder chases the sequence along the weld line to achieve the optimum rate of welding.

摘要： An improved wet scrubber tray provides increased resistance to vibration-induced cracking. The tray is self supporting to eliminate wastage of raw material, and additional internal stiffeners added to the tray make multiple intermediate stiffeners. The connection of the intermediate stiffeners to the perforated bottom plate is changed to eliminate the shop weld in the bottom plate. The holes in the perforated bottom plate are repositioned so that they are moved away from the boundaries of the tray to reduce their influence on boundary conditions. The thickness of the tray material may be increased to lower the vibratory stresses. The mechanism for holding the trays themselves within the spray absorber tower is changed so that the trays are now held down by plate material that is attached to the support grid, but not to the trays. Three field welds are applied to the sides of each tray to hold the trays in place relative to each other and are strategically placed to allow adjacent side stiffeners to act together as a composite section, thus increasing their strength. Elastomeric material such as neoprene is used at the tray-to-grid attachments to increase the damping of the system. Formed features in the trays such as single or multiple ribs, bosses, domes or dimples may also be provided to increase tray stiffness or influence wet scrubber performance.
