Abstract
1,213,437. X-ray film cassettes. AGFAGEVAERT A.G. 29 May, 1969 [4 Dec., 1968], No. 27203/69. Heading H5R. In an X-ray film cassette the film 6 is enclosed between two backing foils 4 and 5 which are connected together along one edge by a tape 8 to form a book-cover-like arrangement, the film and backing-foil assembly being supported in a tray formed by a base-plate 2, e.g. of plastics material, to which the foil 5 is secured, and having upstanding edges 3 along at least three of its sides, the whole being disposed within an envelope 1 made of a laminated structure formed by aluminium foil with plastics material on each side, the evelope being light-proof, gasproof, and flexible, and being evacuated and heat-sealed subsequent to the introduction of the film-holding assembly. For X-ray photographs taken downwards, a lead foil may be included between the inner surface of the baseplate 2 and the adjacent backing foil. Preferably, the plastics layer outside the aluminium foil is a regenerated cellulose film having an outer layer of vinyl chloride-vinylidene chloride copolymer, and that inside the aluminium foil is a polyethylene film, to permit heat sealing. The aluminium foil may be 0À012 to 0À020 mm. thick.
