  • Plural light source and camera to detect surface flaws
    Patent number: 7663745
    Abstract: A method for detecting specular surface flaws on a coated substrate includes impinging visible non-integrated electromagnetic radiation from a first source onto the coated substrate, reflecting the visible non-integrated electromagnetic radiation off the coated substrate into a first photosensitive device, forming a recorded high frequency surface flaw image, and impinging visible coherent electromagnetic radiation from a second source onto a coated substrate at an oblique angle. The visible non-integrated electromagnetic radiation and the visible coherent electromagnetic radiation on the coated substrate are collocated but not combined on the substrate. The visible coherent electromagnetic radiation is reflected off the coated substrate onto a screen material to form a low frequency surface flaw image. The low frequency surface flaw image is recorded to form a recorded low frequency surface flaw image.

  • Charge transport layer processing
    Publication number: 20060014097
    Abstract: This invention is generally directed to charge transport layers and charge transport layer formulations comprising polytetrafluoroethylene particles. This invention is also generally directed to methods of forming charge transport layers on electrophotographic imaging members. The inventive methods of forming charge transport layers provide a stable dispersion of polytetrafluoroethylene.
