Abstract: Apparatus for measuring the optical absorbency of samples of liquids, method and reaction container for its implementation. The apparatus comprises a receiving body for receiving the reaction containers carrying the samples to be analyzed, with means for causing each of the reaction containers to be passed through by a luminous signal of controlled wavelength, having means for conducting it to a scanning head where the luminous signals are picked up by a single CCD sensor, constituting a digital processing system for evaluating the absorbency of the corresponding sample.

Abstract: A method, probe, and system for detecting presence of cavitation in a fluid and measuring cavitation density and intensity of a specific locale in the fluid. A first cavitation void and associated energy perturbation, produced in a first fluid, moves within the first fluid and is received at a very thin plate, which separates the first fluid from a second fluid and is part of a light-proof chamber containing the second fluid. An energy perturbation in the first fluid is received at the thin plate and produces at least one cavitation void or associated energy perturbation in the second fluid; and the energy perturbation in the second fluid is eventually converted into an electromagnetic signal. This signal is received by a photomultiplier and converted to an electronic signal that indicates the presence of cavitation. The system can distinguish between cavitation voids produced at one location and/or time interval and voids produced at another location and/or another time interval.

Abstract: A fiber optic epi-fluorescence imaging system in which the optical fibers are rearranged so that the system can be used for measuring luminescence samples. The system comprises at least two optical fibers (32, 46) or bundles of fibers which lead to a CCD camera (74), the fibers or bundles of fibers from all samples being arranged in two sets, a first set which are formed from a non-fluorescing material and a second set which are formed from a material which may fluoresce but enables the fibers formed therefrom to have a higher numerical aperture than those of the first set.

Abstract: Spectrophotometric apparatus and methodology suitable for continuous and long-term use. The apparatus includes a monochromator providing pre-dispersed monochromatic light to the optical inputs of a pair of fiber optic cables and a translator for alternatively positioning the fiber optic cables at the same location with respect to the monochromator output. One of the cables conducts light to a sample under study while the other cable provides a reference for light intensity measurements. The methodology includes the steps of performing two scans through the monochromator output for each measurement on the sample. The fiber optic cables are moved between scans so that the cable employed in the latter scan occupies the former position of the cable employed in prior scan.

Abstract: A method for separating diamonds from associated gangue in a diamondiferous material. The method comprises the steps of mixing the diamondiferous material with water to form a slurry and passing the slurry through laser radiation of known wavelength in the infra red part of the electromagnetic spectrum to cause Raman spectral scattering of the radiation from the slurry. The scattered radiation is collected and filtered to isolate diamond-relevant radiation and the filtered radiation is analyzed to determine whether it is indicative of the presence of diamond. Finally, on the basis of such analysis, high diamond content slurry is separated from low diamond content slurry.

Abstract: A system for analysis of specific binding complexes. A reaction surface is treated with a specific receptor chemical (SRC) having specific binding properties and is allowed to bind with an unknown reactant to form specific binding complexes (SRC) on the reaction surface. The output of a laser is directed through the reaction surface to a detection mechanism. Shadows in the detected light may be interpreted to detect the presence of the unknown reactant. The unknown reactant may also be quantified. Preferred embodiments of apparatus, and methods of their use, are disclosed for detecting the presence of the unknown reactant within a system for interpreting the results, including interactive system components by which the bases for interpretation may be updated.

Abstract: A system for detecting optically-sensitive properties of sheet materials during manufacture includes a first group of bundles of optical fibers that convey light to selected transmitting locations adjacent one face of the sheet material. The system further includes a second group of bundles of optical fibers that collect and convey light transmitted through the sheet material to a light detector. The light detector measures the intensity of light received from each of the bundles of the second group to provide measurements of optically-sensitive properties of the sheet material at selected cross-directional locations.
