A receive magazine for collecting and transporting sheets of exposed photographic media. The receive magazine includes an elongated, light-tight enclosure having front and back walls, top and bottom walls, and first and second end walls. Sheets of media are gravity fed into the magazine entrance through a collection door on the top wall of the enclosure. The collection door includes a media-receiving slot, a shutter and a spring for biasing the shutter to a normally closed, light-tight position over the slot. A lower downwardly sloping resilient member mounted to the front wall engages the sheets as they are inserted into the magazine and forces the sheets into a vertically stacked arrangement against the back wall of the enclosure, away from the entrance. A ramp surface on the back wall guides sheets being inserted over previously collected sheets. A compound curved surface on the back wall of the enclosure below the ramp surface arcs the sheets to minimize contact during insertion. Collected sheets of media can be removed from the magazine through a retrieve door on the front wall.

Film receive magazine for a laser imager

System for storing and transferring liquid comprising a container for storing liquids, a delivery tube assembly for drawing liquids from said container and transferring said liquids to a second vessel, and, disposed at one end of the delivery tube assembly, a shut-off valve that comprises a casing having a first opening at one end thereof for allowing liquid to enter said casing, a valve head which is normally covering said opening, and a device for biasing said valve head toward said first opening in order to cover same. The container has an actuating device, e.g. a projection, formed on or near the bottom portion thereof, which device actuates the valve head to allow the shut-off valve to open, thereby allowing liquid to be drawn into the first opening in the casing, pass through the casing, and then pass through a second opening in the casing to enter the delivery tube assembly. When the delivery tube assembly and shut-off valve are removed from the container, the valve head closes over said first opening, thereby preventing residual liquid present in the delivery tube assembly from leaking from the tube.
