Patent AU-2001294014-A1 (AU)
Title: Gamma-ray spectrometry
Inventor: RAMSDEN DAVID KEITH
IPC: G01T1/36
Filed: 2001-10-11
Abstract: Different geometries of scintillation spectrometers are disclosed which provide improved resolution over prior art scintillation spectrometers. By ensuring that photons generated by scintillation events occurring in different locations within the scintillation material generate similar light profiles on the photo-detector, the output signal is made less sensitive to the initial interaction site. This can be achieved in a number of ways, such as: by limiting the exit window of the scintillation crystal to a smaller detector, by introducing an optical spacer ( 94 ) between the scintillation crystal and detector ( 99 ), and/or by making the crystal longer than necessary to stop the gamma rays. A principal advantage of these new geometries is that deconvolution of the raw-data is more effective, thus improving resolution.

Patent CA-2001223-A1 (CA)
Inventor: CHANG SHIH-GER
IPC: B01D53/60
Filed: 1989-10-23
Abstract: ABSTRACT    Exhaust gases are treated to remove NO or NOX and SO2 by contacting the gases with an aqueous emulsion or suspension of yellow phosphorus preferably in a wet scrubber.  The pressure is not critical, and ambient pressures are used.  Hot water temperatures are best, but economics suggest about 50°C are attractive.  The amount of yellow phosphorus used will vary with the composition of the exhaust gas, less than 3% for small concentrations of NO, and 10% or higher for concentrations above say 1000 ppm.  Similarly, the pH will vary with the composition being treated, and it is adjusted with a suitable alkali.  For mixtures of NOX and SO2, alkalis that are used for flue gas desulfurization are preferred.  With this process, 100% of the by-products created are usable, and close to 100% of the NO or NO and SO2 can be removed in an economic fashion.
