  • Patent number: 10859451
    Abstract: The prism coupling methods disclosed herein are directed to determining a stress characteristic of an original IOX article having a buried IOX region with a buried refractive index profile that is problematic in the sense that it prevents the original IOX article from being measured using a prism coupler system. The methods include modifying the buried IOX region of the original IOX article in a surface portion of the buried IOX region to form a modified IOX article having an unburied refractive index profile that allows the modified IOX article to be measured using a prism coupler. The methods also include measuring a mode spectrum of the modified IOX article using the prism coupler system. The methods further include determining one or more stress characteristic of the original IOX article from the mode spectrum of the modified IOX article.

    Abstract: A method of making a hollow container-shaped glass article composed of soda-lime-silica glass includes forming a particulate feedstock comprised of pulverized soda-lime-silica cullet particles into a hollow monolithic glass container preform without melting the cullet particles. The hollow monolithic glass container preform has a container shape that includes a wall defining an interior containment space and an opening to the interior containment space and, upon formation, has a temperature above the glass transition temperature of the soda-lime-silica glass. The hollow monolithic glass container preform is eventually cooled into a hollow, amorphous soda-lime-silica glass article, such as a partially-formed container or a finished container, that retains the previously-established container shape.

  • Publication number: 20150111717
    Abstract: A method of manufacturing glass ceramic articles such as glass ceramic plates for cooktops or fireplace windows is provided. The method facilitates the adjustment of a specific hue or a specific absorptivity of the glass ceramic in the visible spectral range. The method is based on the finding that the absorption of light by coloring agents which are appropriate for or present in glass ceramics can be attenuated during the ceramization process by adding substances that have a decoloring effect.

  • Patent number: 8999483
    Abstract: Disclosed is a honeycomb catalyst support structure comprising a honeycomb body and an outer layer or skin formed of a cement comprising an amorphous glass powder with a multimodal particle size distribution applied to an exterior surface of the honeycomb body. The multimodal particle size distribution is achieved through the use of a first glass powder having a first median particle size and at least a second glass powder having a second median particle size. In some embodiments, the first and second glass powders are the same amorphous glass consisting of fused silica. The cement may further include a fine-grained, sub-micron sized silica in the form of colloidal silica. The cement exhibits a coefficient of thermal expansion less than 15×10?7/° C., and preferably about 5×10?7/° C. after drying.

  • Publication number: 20150038313
    Abstract: Systems and methods are described for forming continuous laser filaments in transparent materials. A burst of ultrafast laser pulses is focused such that a beam waist is formed external to the material being processed without forming an external plasma channel, while a sufficient energy density is formed within an extended region within the material to support the formation of a continuous filament, without causing optical breakdown within the material. Filaments formed according to this method may exhibit lengths exceeding 10 mm. In some embodiments, an aberrated optical focusing element is employed to produce an external beam waist while producing distributed focusing of the incident beam within the material. Various systems are described that facilitate the formation of filament arrays within transparent substrates for cleaving/singulation and/or marking. Optical monitoring of the filaments may be employed to provide feedback to facilitate active control of the process.
