Abstract

1,108,781. Film Packs. L. L. DECROP. May 12, 1965 [May 15, 1964], No. 20070/65. Heading G2A. An X-ray film 9 is contained in a pouch 3 of an envelope consisting of front and back walls 101, 100 welded together at their longitudinal marginal edges, at one end, and along a longitudinal centre line (18) Fig. 1, (not shown) to form two compartments (16), 17. The pouch is formed by a band 103 welded to wall 100 so as to extend over approximately one half the height of the envelope. A pocket 105 for a metal screen 106 is formed by welding a flap 104 on to the band 103. Each compartment (16), 17 is provided with a pulling tab (108), 107, the lower ends of which are welded to the wall 100. The compartments contain developing or fixing salts or concentrated solutions. After exposure, water is added to each compartment. The tab 107 is then pulled so as to rupture the wall 100 to allow the developer to flow through an aperture 110a and bathe the exposed film 9. When the film is developed, the fixing solution is applied in a similar manner. In another embodiment Fig. 9 (not shown), only one compartment (125) is provided, and the exposed film is bathed with a monobath solution.
