摘要： A method and apparatus are directed to non-destructive testing for a leak in a sealed package having an interior chamber formed of a gas-permeable portion and a non-gas-permeable portion. A temporary barrier having an aperture is formed to the gas-permeable portion to temporarily seal the gas-permeable portion of the sealed package except at the aperture. A tracer gas is applied through the aperture at the gas-permeable portion, whereby the tracer gas enters into the interior chamber. The concentration of tracer gas is measured at the exterior of the sealed package, thereby testing for a leak in the sealed package.

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： To detect an unpressurized moving container, a fluid such as air is directed at the moving container. Thereafter, a level of deflection of the moving container resulting from the directed fluid is detected. An unpressurized container is indicated when the detected level of deflection exceeds a threshold level. Deflection may be detected by directing a pulse of air or a continuous stream of air against the container. The system is particularly useful in detecting unpressurized, thin-walled aluminum cans.

摘要： A method and system for injecting liquid into containers and for inspecting containers for the presence of certain substances such as potential contaminants such as ammonium salts or amine salts in glass or plastic bottles. A high speed system and method are provided for detecting these contaminants in these bottles. Ammonia and amines can be detected by chemiluminescence of samples of volatiles emitted from the bottles during the high speed inspection process. A solution of Na.sub.2 CO.sub.3 is injected into the bottles in order to enhance the conversion of ammonium or amine salts to free ammonia or amines which are then released as vapors. This enhances the likelihood that a gas-phase detection system such as one using chemiluminescence detection techniques will detect the presence of contaminants containing ammonium salts or amine salts.

摘要： An improved nephelometer for immunochemical complex assay measures forward light scatter in samples. The angle of forward scatter, about 30.degree., is small enough to result in a large amount of forward scatter from the immunochemical complex particles which are to be assayed, whose size is of the order of the wave length of the light used in the optical system. Forward scattering from smaller particles, such as from molecules of buffer, antibody and serum, is constant during the course of a test, and is compensated for by the use of subtraction circuits which are readily and semiautomatically adjusted to subtract proper values, in accordance with the readings taken on standard or "blank" samples of buffer, antibody and serum. Forward scattering from large particles, such as dust, is variable, and results in fluctuating signals, which are electrically processed to ignore the spurious peaks. The results of a test are displayed on a digital read out meter.Also described is a method of and protocol for immunochemical assay, whereby the amount of antigen originally present in a sample is determined by adding a known amount of antibody, and by assaying the "blank" component ingredients and the resulting mixture.
