摘要： An automatic shut-off valve assembly for controlling the fill level in liquid storage tanks, sized to fit through existing filler pipes, includes a tubular body having a flow-blocking diverter plate on the lower end, a series of peripheral through-ports disposed upstream of the diverter plate and a concentric sleeve slidably mounted on the valve body and responsive to longitudinal forces transmitted through a pivotable linkage from a cantilevered float. The linkage permits the float to be extended downward along the valve axis for insertion into the tank, then to rotate outward into a cantilevered position. As the float rises in response to the buoyant force of the rising liquid, the sleeve is urged downward by the linkage to sealingly block the ports and limit flow of liquid through the valve. The tank fill level can be selected by adjusting lengths and angles of linkage members or by manipulating the angle and depth of the valve assembly in the tank.

摘要： A sensor for detecting leakage of a particular fluid into an area to be monitored, such as an interstitial space of a double-walled tank or pipeline, comprises first and second fiber optics. A first end of the first fiber optic is disposed to a source of light and a first end of the second fiber optic is disposed to a detector of light. The second ends of the fiber optics are axially aligned with one another. Under normal circumstances light is transmitted from the source to the first fiber optic across the gap into the second fiber optic, and is detected by the detector. The fiber optics are arranged such that when the sensor is exposed to a material to be monitored, effective light-transmission between the second ends of the fiber optics is prevented, preventing light from being transmitted from the source to the detector. This provides a simple and fool-proof method of detecting leakage of the fluid to be monitored into the area to be monitored.

摘要： The present invention provides methods and apparatus for inexpensively and accurately sensing with the use of a fiber optic guide the presence or absence of a particular substance ("analyte"). The preferred embodiment of the sensor of the present invention comprises a light source, a photodetector, and a loop shaped plastic fiber that is exposed to the environment and that acts as a sensing element. In the preferred embodiment, the fiber optic guide comprises a core and a cladding, either of which are coated with a coating that is selected to at least partially degrade in the presence of the analyte. The coating is selected to have an index of refraction below that of the core but sufficiently large to allow at least some light to escape from the core even in the absence of the analyte. A decrease in the amount of light is detected when the analyte is present. Alternatively, the coating is selected to have an index of refraction just above or greater than the core, causing an increase in the amount of light that is detected when the analyte is present.

摘要： A system and method for obtaining information from sensor systems is disclosed. Light, corresponding to information from a plurality of sensors, is projected from a plurality of optical waveguides to a photodetector. The photodetector is coupled to an analog-to-digital converter, which converts an image detected by the photodetector to digital data, which is then stored in a digital memory. A processor extracts information regarding the state of the sensors by processing the digital data.

摘要： A method of monitoring thinning of pipe walls in a piping system including selecting locations to be monitored, normally those pipes particularly susceptible to thinning from erosion/corrosion, boring holes in the outer surfaces of the pipes at the selected locations to depths greater than the thickness at which the pipes will rupture to leave predetermined residual wall thicknesses between the ends of the holes and the inner surfaces of the pipe walls, inserting tracer materials in the holes to be released in the pipes when pipe wall thinning exceeds the residual wall thicknesses of the holes, monitoring fluid flow through the piping system to sense the presence of tracer materials in the fluid, and determining the location of the hole from which a sensed tracer material was released to permit pipe wall thinning to be determined prior to pipe rupture allowing repair or replacement during scheduled downtime of the piping system. Preferably, a series of spaced holes are bored to differing depths at each location such that, knowing the difference in depth and thus residual thickness between holes and the time period between detection of tracer materials from each hole, the rate of pipe wall thinning can be determined, and the period of time in which the pipe can be safely repaired can be calculated.

摘要： A method and apparatus particularly for monitoring leakage of a fluid contained within a double-walled tank into its interstitial space is disclosed. The sensor includes an element which is subject to physical change upon exposure to the material contained in the tank. The condition of the element is remotely monitored to determine leakage. In the case of an underground tank or oceangoing vessel, a second similar sensor sensitive to water may be employed to differentiate leakage into the interstitial space of the material in the tank from ground or sea water.
