Patent ID: 7030393

Claim:
A system for applying radiant energy to articles, a carousel having a hollow configuration and movable continuously in a loop at a substantially constant speed, the carousel defining compartments for holding the articles for movement with the carousel, an accelerator disposed relative to the carousel to provide radiant energy to the articles in the carousel during the movement of the carousel continuously at the substantially constant speed in the closed loop, a first member disposed within the hollow configuration of the carousel and having the configuration of the loop and having properties of shielding against the radiant energy from the accelerator, a second member disposed externally of the carousel and having the configuration of the loop and having properties of shielding against the radiant energy from the accelerator, a motor for driving the carousel in a first direction, and a control system for detecting a fault, for stopping the motor upon the detection of the fault, for reversing the motor after the stoppage of the motor and for resuming the operation of the motor in the first direction upon a clearing of the fault.
