  • Patent number: 9085484
    Abstract: A glass article including: at least one anti-glare surface having haze, distinctness-of-image, surface roughness, and uniformity properties, as defined herein. A method of making the glass article includes, for example, depositing sacrificial particles on a surface of the article; and contacting the resulting particulated surface with an etchant. A display system that incorporates the glass article, as defined herein, is also disclosed.
    Type: Grant
    Filed: April 20, 2011
    Date of Patent: July 21, 2015
    Assignee: Corning Incorporated

  • Publication number: 20150160376
    Abstract: A glass article including: at least one anti-glare surface having haze, distinctness-of-image, surface roughness, and uniformity properties, as defined herein. A method of making the article having an anti-glare surface includes, for example, forming a protective film on selected portions of at least one surface of the article; contacting the at least one surface with a liquid etchant; and removing the protective film from the surface of the article to form the anti-glare surface. A display system that incorporates the glass article, as defined herein, is also disclosed.

  • Publication number: 20150114041
    Abstract: A method of making a strengthened glass article includes providing a flat glass article having a select contour and a glass surface covered by a protective coating layer. The protective coating layer is removed from the glass surface without touching the glass surface with any solid object. Immediately after the protective coating layer is removed from the glass surface, the flat glass article is subjected to an ion-exchange process to strengthen the flat glass article and improve the resistance of the flat glass article to subsequent damage.

  • Patent number: 8393175
    Abstract: Methods for extracting strengthened glass substrates from glass sheets are described herein. In one embodiment, the method for extracting strengthened glass substrates from glass sheets comprises forming a plurality of channel segments in the glass sheet. The plurality of channel segments may extend through the thickness of the glass sheet and are separated by remnant glass webs connecting the glass substrate to the glass sheet. The plurality of channel segments extend around a perimeter of the glass substrate. Thereafter, the glass sheet is strengthened by ion-exchange. The glass substrate is then separated from the glass sheet by severing the glass substrate from the remnant glass webs.

  • Patent number: 8137637
    Abstract: A particulate filter includes first and second honeycomb substrates. An outlet face of a first substrate is positioned against an inlet face of a second substrate such that channels extending longitudinally through the substrates are aligned to form continuous channels. A continuous skin is joined to each of the substrates to form a unified substrate. A portion of the continuous channels are selectively plugged to form a wall flow filter.
