Abstract: The system constructed according to the present invention operates by properly positioning a base compact disc (CD) onto a cutting table and then cutting the CD to a preprogrammed shape. Base CDs are stacked on an elevator system. The CDs include one side on which data is recorded, and another side on which the CD label is printed. A robotic arm with a vacuum gripper then picks-up a CD from the stack and moves the CD to a cutting table. While the arm moves the CD, a machine vision system takes a picture of the CD label and compares the picture to an image of the label stored in data. An image mapping program then determines the rotational orientation of the CD by comparing the picture and data image. Once the orientation of the disc is known, the robot arm rotates the disc a calculated amount so that it can then be placed on the cutting table in a proper normalized orientation. The CD is held in place on the cutting table by a vacuum chucking system.

Abstract: The invention is a method and apparatus for purging an oxidant or residual fuel by controlled oxidation within a closed loop system. The particular application disclosed can operate to purge oxygen from an anode loop of a fuel cell just prior to startup, and can also operate to consume the remaining hydrogen or fuel at shutdown. The method employs the addition of additional fuel to a feed stream within the anode loop to a level that will through oxidation within the apparatus deplete the desired amount of oxygen. The method also employs the addition of air into a hydrogen feed loop that through oxidation within the apparatus consumes the hydrogen. Oxidation is accomplished first by diffusion burning and then catalysis to accomplish the depletion quickly. The method and apparatus eliminates the need for a separately stored inert gas purge tank and associated systems.
