ABSTRACT:
An automatic x-ray film feed uses a timer and relay system to automatically develop a multiplicity of film slides one-by-one in an x-ray processor without requiring a user to manually advance the slides after each slides in developed. The timer activates a motor through a relay system and the film feed advances a single slide into the processor with a motor and roller assembly. After the film leaves the magazine, a trip switch is triggered, shutting off the motor and halting advancement of the next slide in the magazine. The timer than reactivates the motor based on a pre-selected interval set on the timer, facilitating movement of the next undeveloped film slide in the magazine.
