  • Patent number: 11897211
    Abstract: Disclosed herein is a method and apparatus for automatic extrudate loading and alignment. An extrudate handling system includes a head end assembly and an imaging device (which may be part of the head end assembly). The imaging device is configured to image an end face of an extrudate, and generate, during translation of the extrudate, an imaging output signal indicative of a rotational position of the end face of the extrudate. The head end assembly includes a rotational effector to rotate the extrudate during translation thereof and a fixed effector rotationally fixed relative to a track. The extrudate handling system is able to determine the rotational position of the web angle of the extrudate and precisely adjust the rotational position while linearly translating the extrudate along the track.

  • Patent number: 11891687
    Abstract: A method is provided for manufacturing an article comprising a transparent conductive material, wherein a transparent conductive material (e.g., indium tin oxide) is deposited onto a substrate (e.g., fused silica) by physical vapor deposition, then annealed at high temperature (i.e., at least 450° C.) in a nitrogen atmosphere. The resulting article comprises a transparent conductive material that reduces the trade-off between low resistivity (or sheet resistance) and high near infrared transmission. For example, the transparent conductive material thus obtained may possess a transmission of at least 80% at 1550 nm while having a resistivity of less than or equal to about 5×10?4 Ohm-cm and a Haacke figure of merit of at least about 40×10?4??1.

  • Patent number: 11891330
    Abstract: The system and methods for marking an optical fiber with color-coded marks disclosed herein include forming closely spaced multiple ink streams, with at least two of the ink streams having different colors. The optical fiber moves over a fiber path that resides adjacent the ink streams. The fiber path and the ink streams are made to briefly intersect so that the ink streams form on the outer surface of the optical fiber a group of spaced apart individual marks, wherein the group of individual marks constitute a color-coded mark. Repeating this marking process at different times as the fiber moves over the fiber path forms spaced apart color-coded marks along the length of the fiber. Subsequent drying and overcoating of the marks fixes and protects the color-coded marks.
