Abstract: 1,211,194. Microscopy. NATIONAL RESEARCH DEVELOPMENT CORP. Oct.31, 1967 [Aug.1, 1966], No.34410/66. Heading G2J. [Also in Division G1] A dispersion of particles is laid down in a narrow strip on a film base for microscopic examination by means of a two-bladed feeder. A 35 m.m. perforate or imperforate safety film base strip 6, Fig. 3, is wound continuously or in strips between spools 10, 15 and passes through inspection stations 13. The sample is applied by applicator 16 as the film passes round the sprocket 11, and forms a thin strip on the film base. If chromatographic separation of sample components occurs across the strip, the inspection stations may be trained on different lateral parts of the strip. The inspection stations may be visual microscopes, photo-diode matrices, flying-spot scanners or photo-electric devices responsive to distortions of moirÚ fringe patterns. They may respond to reflected, transmitted or fluorescent light or heat and the phase contrast microscope principle may be used. The radiation may be polarized or limited to a broad or narrow band of the spectrum. A cylindrical lens or fibre optics may be provided between the film and the inspecting station. The sensers may respond to gamma-rays. A magnetic stripe may be provided on the film and used for indexing and recording the results of an inspection alongside the inspected area. The results may be combined with other information before recording, and used to control subsequent inspection stations. The feeder 16, comprises two blades 18, Fig.4, whose spacing is adjustable by a screw 20. The sample contained between the blades flows from their tips onto the film 6 after the small gap has been temporarily bridged. Sedimation of the sample may be avoided by magnetic agitation of the blades. The space between blades 18 may be supplied with sample through a capilliary tube 24 or by a pump. The sample may be taken up in a volatile dispersion medium and a suitable binder or a film solvent such as acetone or acetic acid. When the strip has dried it may be sealed by nitrocellulose lacquer. The specimen may be stained before or after deposition. The apparatus may be used for exfoliative cytology e.g. cervical smear tests, haematology, chromosome and bacteriological study, crystal recognition and particle size analysis of pigment powders. To these ends, the inspection stations may measure longest chords and bi-sectors thereof, centroids and second moments of particles and the positional relationship between these features.
