Abstract: A control apparatus for controlling a thickness of a substrate, such as a glass ribbon. The control apparatus comprises a laser assembly and a shielding assembly. The laser assembly generates an elongated laser beam traveling in a propagation direction along an optical path. The shielding assembly comprises at least one shield selectively disposed in the optical path. The shield is configured to decrease an optical intensity of a region of the elongated laser beam. The shielding assembly is configured to change an intensity profile of the elongated laser beam from an initial intensity profile to a targeted intensity profile. A desired targeted intensity profile can be dictated by an arrangement of the shield(s) relative to the optical path, and can be selected to affect a temperature change at portions of the substrate determined to benefit from a reduction in thickness.

Abstract: An aluminosilicate glass, including in mole percent on an oxide basis, MgO+CaO+SrO+Li2O+ZnO+Y2O3+ZrO2+La2O3+TiO2+Nb2O5+Ta2O5 in a range of from 5 mol % to 25 mol %. The glass is processable by (i) flowing the glass in a molten state over forming surfaces to form a glass ribbon, the forming surfaces converging at a root and (ii) drawing the glass ribbon using pulling rollers to form a glass sheet, wherein the pulling rollers are spaced at a pulling roller distance from the root, and wherein the glass exhibits a viscosity curve slope obtained by plotting a temperature gradient to increase a root viscosity of the glass at the root, to a higher viscosity at one of several positions between the root and the pulling rollers, and a viscosity of the glass at the pulling rollers. The glass comprises a liquidus viscosity, the root viscosity being less than the liquidus viscosity, and the glass comprising a viscosity curve slope that prevents a baggy warp defect. In certain embodiments, when the root viscosity of the glass is in a range of from about 70 kP to about 90 kP, and the viscosity of the glass at the pulling rollers is greater than 90 kP and less than or equal 1×108 kP, the temperature gradient is less than 150° C.

Abstract: Apparatuses for making a laminated glass ribbon may include an upper forming body including an outer forming surface bounded by a pair of upper dams, and a lower forming body disposed downstream of the upper forming body and including an outer forming surface spaced from the outer forming surface of the upper forming body by an interior gap. An edge guide may be disposed along an interior upper dam wall and spaced apart in the interior gap from the lower forming body. Surfaces exterior to the outer forming surfaces of the upper and lower forming bodies may abut and be joined. A formed glass ribbon having a core glass layer and a pair of clad glass layers may include inner and outer portions that have substantially equal thickness ratios based on a glass core layer thickness compared to a combined glass cladding layer thickness in each portion.

Abstract: Disclosed are methods for compensating the varying weight of a glass ribbon the glass ribbon is drawn from a molten glass forming material, and an apparatus therefore. The weight compensating apparatus is configured to apply a force to the glass ribbon that is inversely proportional to the weight of the glass ribbon such that as the glass ribbon weight increases, the force applied to the glass ribbon by the weight compensating device decreases.

Abstract: An apparatus for making a glass sheet including a forming apparatus, a transition member, and a heat transfer device. The forming apparatus forms a glass ribbon from a supply of molten glass. The transition member encloses the glass ribbon adjacent the forming apparatus, and defines an interior space through which the glass ribbon passes. The heat transfer device is disposed within the interior space, and comprises a tube and a fin. The tube defines an exterior surface and an interior passage. The fin projects from the exterior surface. With this construction, the heat transfer device functions to extract heat radiated by the glass ribbon while minimizing the formation of flow vortices.
