Disclosed is a method of forming a glass article. In the method, a mid-frame is adhered to a glass sheet in a flat configuration. The glass sheet has a first major surface and a second major surface opposite to the first major surface. The mid-frame is adhered to the second major surface of the glass sheet. The glass sheet and mid-frame are bent over a forming surface of a chuck so that the glass sheet is in a curved configuration. The forming surface includes a first radius of curvature of 20 mm or more, and the first major surface of the glass sheet conforms to the forming surface. A frame is attached to the mid-frame, and the frame holds the glass sheet in the curved configuration.

Strengthened glass-based substrates having a first outer region compressive stress and a first side having first coating thereon are disclosed. The first coating comprising a material selected to have a first coating Young's modulus value, a first coating thickness, and a first coating stress that is either neutral or compressive, such that the absolute value of first outer region compressive stress is greater than the absolute value of the first coating stress. Methods of making glass-based articles are provided, and glass-based articles having coatings that provide different strength values and/or reliability on different sides of the glass-based articles are also disclosed.

Honeycomb extrudate is made by extruding a plasticized ceramic-forming batch material to form a length of wet honeycomb extrudate, transferring the extrudate to a support tray, and transferring the tray and extrudate to a dryer, the tray being capable of contactingly supporting greater than one-third of the circumferential surface of the wet extrudate. The extrudate is subject to reduced handling damage, e.g. from forces of gravitational and/or lateral acceleration arising during transfer.

Apparatus and equipment for making glass sheet from a glass ribbon including scoring, bending and separation in vertical state with improved glass ribbon stability provided by edge restrainers located above the score-line that also travel with substantially the same vertical velocity with the elastic ribbon. The edge restrainers on both sides of the glass ribbon serve to limit the motion and perturbation of the ribbon during scoring, bending and separation, advantageously by tensioning the glass ribbon where needed. The invention can reduce disturbance of the glass ribbon in upstream visco-elastic and/or viscous zones due to scoring, bending and separation, therefore enhance forming process stability and product attributes such as thickness variation, stress and stress variation, and the like. The invention can be particularly advantageous for making glass sheet with large width and/or low thickness using the fusion down-draw, slot down-draw, re-draw down-draw, and other down-draw processes.

A stabilizing system is described herein that reinforces a bowed profile of a downward moving glass sheet which helps to reduce the creation of stress within the glass sheet. In another embodiment, the stabilizing system can also form a rigid zone within the glass sheet which blocks or dampens any disturbances (motion) to the glass sheet that is caused by the scoring and separating of the glass sheet from transferring up the glass sheet. In yet another embodiment, the stabilizing system can also flatten the glass sheet before the scoring and separating of the glass sheet which is desirable because it enables a laser scoring mechanism to cut the glass sheet with the required edge straightness and avoids having to perform another precision cutting process.

A process and apparatus for cutting a continuous glass ribbon involving the use of edge restrainers such as suction cups and clamps connected to an actuator of a robot tooling through a flexible linkage capable of reciprocal motion in the direction of the ribbon velocity. The use of the flexible linkage reduces peak pulling-force when the glass ribbon is pulled or pushed laterally to during bending and separation along a pre-formed score-line. The invention can be advantageously used in the bottom of the draw of a vertical down-draw forming process.

Methods are disclosed for inspecting a cylindrical porous ceramic body by positioning a diffuser near, and spaced apart from, the first end of a ceramic body; flowing a tracer flow toward the diffuser, wherein a first portion of the tracer flow passes through the diffuser, and a second portion of the tracer flow does not pass through the diffuser, the first and second portions of the tracer flow then entering the first end of the ceramic body, wherein the average velocity of the first portion of the tracer flow entering the ceramic body Vis lower than the average velocity of the second portion of the tracer flow entering the ceramic body V; directing light toward the second end of the ceramic body; and detecting reflected light coming from a location proximate the second transverse face at the second end of the ceramic body.

A method of applying a cement mixture to an exposed matrix of intersecting walls of a honeycomb body is disclosed. The method may include the steps of providing an applicator, feeding the cement mixture into applicator, forcing the cement mixture to exit the applicator with a substantially uniform velocity, while depositing the cement mixture on the exposed matrix of the honeycomb body.

Experimental data is presented which shows that laser scoring of glass sheets () with existing techniques produces unacceptable levels of residual stress in the separated sheets as the scoring speed is increased. Methods for solving this problem are disclosed which employ elongated and, preferably, asymmetrically-truncated laser beams (). The methods allow glass sheets () to be scored at speeds of 1000 mm/s and above with low levels of residual stress, e.g., levels of residual stress which are less than or equal to 500 psi. Such low levels of residual stress translate into low levels of distortion during the manufacture of display panels (e.g., LCD panels) as well as in improved properties of the separated edges. The methods can be used with glasses of various types including glasses having low coefficients of thermal expansion.
