  • Single-fire two-step soak method
    Patent number: 9005517
    Abstract: A method for making a cordierite filter article, including: firing an extruded green body batch composition according to: a first temperature ramping from ambient temperature up to a first soaking temperature; a first soaking at a temperature of at least 1255° C. for at least 2 hours; a second temperature ramping from the first soak temperature down to a second soak temperature; and a second soaking at a temperature of at least 1250° C. and at least 5° C. below the first soaking temperature, as defined herein.
    Type: Grant

  • Bend insensitive fiber with reduced heat induced loss
    Patent number: 8055110
    Abstract: Microstructured optical fiber for single-moded transmission of optical signals, the optical fiber including a core region and a cladding region, the cladding region including an annular hole-containing region that contains non-periodically disposed holes. The annular hole containing region is doped with at least one dopant selected from fluorine and chlorine. The optical fiber provides low bend loss as well as low heat-induced splice loss.
