  • Patent number: 8016968
    Abstract: There is provided a process for producing a seamed, flexible electrostatographic imaging member belt comprising providing a flexible, substantially rectangular, electrostatographic imaging sheet having a first major exterior surface opposite and parallel to a second major exterior surface and a first marginal end region of said sheet opposite and parallel with a second marginal end region; shaping said first marginal end region at an angle to form a first new sloping surface between the first major exterior surface and the second major exterior surface, shaping said second marginal end region at an angle to form a second new sloping surface between the first major exterior surface and the second major exterior surface, wherein the second new sloping surface is substantially parallel with the first new sloping surface; forming the sheet into a loop and overlapping said first new sloping surface with said second new sloping surface to form a mated region; and, joining said first new sloping surface to said seco

  • Patent number: 7685913
    Abstract: There is provided an apparatus for producing a cross-sectional angular surface along a substrate, such as a flexible electrostatographic imaging member belt. The apparatus may include a support body, and a blade support member connected to the blade support body. The blade support member comprises a cutting blade having a straight blade edge. The cutting blade may be positioned at an angle relative to a plane of an associated substrate to be cut.

  • Patent number: 7455802
    Abstract: A stress/strain relief process for a flexible, multilayered web stock includes providing a multilayered web stock including at least one layer to be treated, the at least one layer to be treated having a coefficient of thermal expansion significantly differing from a coefficient of thermal expansion of another layer; passing the multilayered web stock over and in contact with a first wrinkle-reducing roller that spontaneously creates transverse tension stress in the at least one layer to be treated; heating at least the at least one layer to be treated above a glass transition temperature Tg of the at least one layer to be treated to thereby create a heated portion of the at least one layer to be treated, a portion of the web stock in proximity to the heated portion of the at least one layer to be treated thereby becoming a heated portion of the web stock; inducing curvature in the heated portion of the web stock; and cooling the heated portion of the web stock at said curvature.

  • Patent number: 7280791
    Abstract: A weldable intermediate transfer belt having a substrate with a homogeneous composition of polyaniline in an amount of from about 2 to about 25 percent by weight of total solids, and a thermoplastic polyimide in an amount of from about 75 to about 98 percent by weight of total solids, and the polyaniline has a particle size of from about 0.5 to about 5.0 microns, and an apparatus for forming images on a recording medium and incorporating the intermediate transfer belt.

  • Patent number: 7139519
    Abstract: A welded intermediate transfer belt and process for making the same having a substrate made primarily of at least one polyimide polymer. The weld may be ultrasonically or otherwise welded and may have favorable properties such as relatively thin seam thickness and small weld steps. The weld may be overlapped or miter cut.

  • Patent number: 6171198
    Abstract: A merry-go-round with a frame supported for rotation by a plurality of driven wheels, the merry-go-round having a space for a wheel chair and a space for a non-wheel chair bound person. Each separate space on the merry-go-round is associated with a respective crank assembly such that a person in that space can drive one of the driven wheels through a crank. A plurality of smaller wheels secured to the underside of the frame provide additional support for the merry-go-round. The person in the non-wheel chair bound space can stand on the frame, or in an alternate embodiment can sit on a chair. Because the merry-go-round has spaces for both wheel chairs and non-wheel chair bound people, both can use the merry-go-round at the same time.
