Abstract: A scannable detector system for echelle grating spectrometers is disclosed in which a photodetector is positioned behind an aperture plate having a plurality of apertures corresponding to focal positions of the spectral array eminating from the grating. The detector is arranged to scan from aperture to aperture to measure the presence of individual wavelengths in the array. Additionally, the detector may be removed from the field of the plate to permit the substitution of a non-scannable array of detectors and an associated masking aperture plate to simultaneously measure the presence of a plurality of wavelengths in the spectral array.

Abstract: A spectrometer readout system with storage capacitors for temporarily storing output signals generated by a series of photomultiplier tubes that are positioned to monitor selected spectral lines. A voltage-time converter sequentially discharges the capacitors to a preset level and converts the stored voltages into signals that are linearly related to a known signal and an unknown signal. The output of the voltage-time converter defines the discharge time period which is measured and stored by a computer.

Abstract: An improved atomic fluorescence spectrometer in which good correlation between output signal and concentration of sample is achieved by providing a dual channel biomodal detection system for the detection of modulated signals. This detection system provides means to allow for scattered light intensity as well as non-fluorescent emitted light. An improved method of detection of square or approximately square modulated signals allows information to be derived from the signals during up to 80 percent of elapsed time. Attachment of memory means with arithmetic capability allows automatic processing of output data.

Abstract: An improvement in the processing of bituminous sands is described, whereby the concentration of bitumen in tar sand feed is measured by infrared light reflected from the tar sand surface. Near infrared is shone onto the surface of the incoming tar sand and reflected light is collected and passed through two parallel filters, one being a measuring filter having a wavelength range of 2180 to 2260 nm and the other being a reference filter having a wavelength range of 2270 to 2350 nm. The beams emerging from the filters are measured electronically and the resulting signals are separately integrated and amplified by electronic means. The ratio of the amplified signals is used to provide a read-out signal responsive to the bitumen concentration. The results may be used to adjust processing conditions in the extraction process to allow for the variations of bitumen in the feed.
