    Abstract: The apparatus and methods include moving an optical fiber over a fiber path that includes a marking location at which resides a marking unit that dispenses an ink-jet stream. A centering method is performed whereby the optical fiber is incrementally moved in a lateral direction through the path of the ink-stream and the mark number density of marks formed on the optical fiber is measured along with the optical fiber position. A process window is defined by the range of lateral fiber positions over which a target mark number density is formed on a consistent basis. A controller calculates an optimum fiber path position and stores it memory for future reference while also moving the fiber path to the optimum position. The initially wet ink marks are dried and the fiber coated with a transparent protective overcoat to form a coated and marked optical fiber.

    Abstract: The apparatus and methods include moving an optical fiber over a fiber path that includes a marking location at which resides a printer unit. The moving optical fiber has an amount of undamped fiber vibration that can exceed a fiber vibration tolerance at high fiber speeds. The printer unit is configured to dispense ink onto the optical fiber to form wet ink marks along the optical fiber as it moves past the marking location. The wet ink marks are dried and counted for quality control. The marked optical fiber is then covered with an overcoat to protect the ink marks. A position sensor measures an amount of vibration of the optical fiber substantially at the marking location. One or more vibration dampers disposed along the fiber path are used to reduce the fiber vibration below the fiber vibration tolerance. This allows for high-speed marking of the optical fiber.

    Abstract: A method of marking an optical fiber includes forming an ink stream, moving an optical fiber over a fiber path adjacent the ink stream, and intermittently deflecting the ink stream with a gas jet so that the optical fiber at least partially enters the deflected ink stream so that the ink from the deflected ink stream forms spaced apart marks on the optical fiber outer surface. An optical fiber marking apparatus is also disclosed that includes payout and take modules that move the optical fiber over the fiber path, a marking unit configured to form an ink stream adjacent the fiber path, and an ink stream deflection device that causes the ink stream to deflect and overlap the fiber path so that ink from the ink stream forms spaced apart marks on the outer surface of the optical fiber.

    Abstract: A method of marking an optical fiber is disclosed, wherein the method includes forming an ink stream, moving an optical fiber over a fiber path that resides adjacent the ink stream, and periodically changing the position of the fiber path so that the optical fiber at least partially enters the ink stream so that the ink from the ink stream forms spaced apart marks on the outer surface of the optical fiber. An optical fiber marking apparatus is also disclosed that includes payout and take modules that move the optical fiber over the fiber path, a marking unit configured to form an ink stream adjacent the fiber path, and a fiber positioning device that causes the optical fiber to periodically intersect the ink stream so that ink from the ink stream forms spaced apart marks on the outer surface of the optical fiber.

    Abstract: A glass article including: at least one anti-glare surface having haze, distinctness-of-image, surface roughness, uniformity properties and sparkle properties, as defined herein. A method of making the glass article includes, for example, slot coating a suspension of particles on at least one surface of the article to provide a particulated mask covering from about 40 to 92% of the coated surface area; contacting the at least one surface of the article having the particulated mask and an etchant to form the anti-glare surface, and optionally continuously polishing the suspension of particles just prior to slot coating. A display system that incorporates the glass article, as defined herein, is also disclosed.

    Abstract: The present disclosure is directed to a method, called herein the “wrap-around” method, of applying polymers to glass articles having one or a plurality of shaped edges. The glass articles have a selected length, selected width and selected thickness which define a first face, a second face and one or a plurality of edges. Circular and oval articles are deemed to have a single edge. Rectangular, square, hexagonal, octagonal, and other shapes having angled corners are deemed to have a plurality of edges defined by the faces and thickness of the glass. The glass articles can be either (1) flat or planar as shown in FIG. 6a, which is sometimes referred to as a two dimensional or 2D article, or (2) three dimensional or 3D article in which the glass article is non-planar as is illustrated in FIG. 7b.
