  • Patent number: 7185388
    Abstract: One embodiment of the improved squeegee has a front deflector bar, and a plurality of material folding devices that are oriented and positioned on the front deflector bar such that the material encountering the front deflector bar is folded back onto material not yet encountered by the front deflector bar. The front deflector bar has an inside wall with a predetermined configuration and the material folding devices extend from this inside wall. The material folding devices may extend substantially perpendicular from the inside wall or at other angles. The improved squeegee may also have a back support section and a blade. The front deflector bar may be operatively connected to the back support section. The blade may be secured at least partially between the back support section and the front deflector bar.

  • Patent number: 6514072
    Abstract: This invention is for a novel method of treating carbon fiber. Carbon fiber is a very unique material and its processing requires high temperatures. Also since carbon fibers are lightweight and porous, heating is accomplished in this process by radiation with a heated gas flowing through the material. Also a float is used to transfer the material from one process station to another so as to prevent delaminating of the carbon fiber.

  • Patent number: 6464493
    Abstract: A multi-axis rotary seal system to provide a gas-tight seal between a stationary hood and the end of a rotating tube kiln comprises a stationary hood positioned at the end of the rotary tube and having extended therefrom, a fully flexible bellows attached at the other end to a structural ring which, in turn, is attached to a graphite ring, slidably pressed against a flange on the rotary tube to form an atmospheric seal. The structural ring is held to the stationary hood by multi-axis supports that allow movement of the ring in three axial directions. In operation, during expansion and contraction of the rotating tube and eccentricities of motion, the integrity of the slidable seal formed by the graphite ring against the mating surface of the tube flange, is maintained by a biasing device pressing the graphite ring and the tube flange together in slidable engagement.
