The spent pods and wet traps are transferred from the carrier web, after processing, to an image bearing web from which image media was transferred to the image frames during processing.

Abstract: This invention relates to a device for monitoring exposure to influences, such as ionizing radiation, adverse to the human body. The device includes a support which carries material sensitive to the influence. The material is demarcated into a plurality of discrete zones each of which is processable individually by processing composition stored in a respective reservoir. Each reservoir is dischargeable individually to process its related zone. The sensitive material produces an indication visible externally of the device if the exposure to radiation has been greater than a predetermined threshold. The zones are processable at will in single succession.

Abstract: An improvement to instant photograph film wherein spotted uneven concentration is effectively prevented, particularly under high temperature conditions, from being produced in the image zone edge portion during the formation of images after pressure and treatment. A zone of grooves is formed, in the width direction along the cross edge portion, in at least one face of the mutually opposite faces between a first sheet and a second sheet adjacent a treating liquid container. Thus, the thickness of the spread treating liquid is made uniform and increases near the grooves to reduce the floating of the second sheet. The second sheet's floating or rising is suppressed due to the increase in contact area with the viscous treating liquid. Trapped air is caught to prevent it from reaching the image zone portion. Since a partial air layer is prevented from being formed between the first sheet and the second sheet, the spotted uneven concentration does not appear.
