摘要： A highly selective, sensitive, fast detection system and method are disclosed for detecting vapors of specific compounds in air. Vapors emanating from compounds such as explosives, or stripped from surfaces using heat and suction from a hand-held sample gun, are collected on surfaces coated with gas chromatograph (GC) material which trap explosives vapors but repel nitric oxide, then are desorbed and concentrated in one or more cold spot concentrators, A high speed gas chromatograph (GC) separates the vapors, after which specific vapors are decomposed in two pyrolyzers arranged in parallel and the resulting nitric oxide is detected, A low temperature pyrolyzer with silver produces NO from nitramines or nitrite esters; a high temperature pyrolyzer decomposes all explosives vapors to permit detection of the remaining explosives, Also disclosed is a series arrangement of pyrolyzers and gas chromatographs and an NO detector to time-shift detection of certain vapors and facilitate very fast GC analyses, The use of hydrogen as a carrier gas, plus unique collectors and concentrators, high speed heaters, NO detectors, and very fast, temperature-programmable GC's enhance selectivity, sensitivity and speed of detection,

摘要： To detect a turbid contaminant in a moving container, radiant energy having a wavelength that is absorbed by contents of the moving container that include the turbid contaminant at a different level than energy having the wavelength is absorbed by contents of the moving container that include a non-contaminant is directed into the container. Thereafter, a level of radiant energy scattered by contents of the container is detected. The presence of a turbid contaminant is indicated when the detected level of scattered radiant energy differs from a threshold level.

摘要： Disclosed are a method and apparatus for high speed, selective detection of vapors of specific compounds, particularly nitrogen-containing compounds, utilizing, a bypass branch and high speed gas chromatography for improved selectively and sensitivity of detection. A system with two gas chromatographs (GC's) alternating in series with two pyrolyzers provides two time intervals of detection in a downstream detector, with the second time interval containing signals delayed and further separated relative to signals from the first time interval. The bypass branch, in diverting a portion of the flow of gas samples from passage through the second gas chromatograph and second pyrolyzer, avoids interferences in the first time interval of detection from non-GC-retained compounds decomposed in the second pyrolyzer. Also disclosed is an arrangement for rapid, precise heating of vapor concentrator tubes in which vapors are rapidly focussed and then injected into a GC, and for rapid, precise heating of the GC's.

摘要： Disclosed is a walk-in inspection apparatus for active production of air samples containing vapors of explosives, drugs, or other substances carried by a person. The apparatus includes a U-shaped booth with an open end through which a person walks past walls which may contain a metal detector, then stands facing a vertical end wall. In the collection of an air sample a blower outside the booth sucks a large volume of air around the person and horizontally through a vertical array of shaped funnels in the end wall and through ducts connected to a collection manifold for subsequent analysis. Infrared heaters in the end wall heat the clothing and skin of the person during sampling, and many small nozzles extending through the end wall direct low volume, high momentum pulsed jets of puffs of air at the person to dislodge vapors, expel air from beneath clothing, and disrupt stagnant boundary layers of air near the person. Curved shapes of portions of the booth and funnels provide smooth, low loss airflow, and height and distance sensors facilitate automatic operation of the inspection apparatus.

摘要： Disclosed is a walk-in inspection apparatus for active production of air samples containing vapors of explosives, drugs, or other substances carried by a person. The apparatus includes a U-shaped booth with an open end through which a person walks past walls which may contain a metal detector, then stands in front of a mesh screen facing a vertical end wall containing a vertical array of shaped funnels. Light-transmissive wall sections near the end wall help encourage entry of the person into the booth, and the light colored mesh screen draws attention of a person in the booth away from the darker funnels. In the collection of an air sample a blower outside the booth sucks a large volume of air around the person and horizontally through the funnels in the end wall and through ducts into a collection manifold for subsequent analysis. During sampling, infrared heaters in the end wall heat the clothing and skin of the person and many small nozzles extending through the end wall direct pulsed jets or puffs of air at the person to dislodge vapors, expel air from beneath clothing, and disrupt stagnant boundary layers of air near the person. Substantially all of the air drawn around the person is collected, and curved shapes of portions of the booth, funnels, and ducts provide smooth, low loss airflow to the collection manifold.

摘要： A controller is disclosed for controlling the operation of selected electro-mechanical devices without the use of a microprocessor or similar computing machines. The controller includes a memory programmed to output a data word each time the memory is advanced to its next successive memory address. Responsive to the data word, an electro-mechanical device, identified by the data word, is actuated to perform its function. As the function of an electro-mechanical device is completed, a sensor develops a control signal for altering the internal count of a counter. The counter, in turn, advances the memory to its next address for outputting its next data word. The cycle continues as the memory is advanced through its addresses and selected electro-mechanical devices are successively actuated to perform their assigned functions.
