A strengthened glass sheet product along with a process and an apparatus for strengthening a glass sheet are provided. The process comprises cooling the glass sheet by non-contact thermal conduction for sufficiently long to fix a surface compression and central tension of the sheet. The process results in thermally strengthened glass sheets having improved breakage properties.

Thin safety glass having improved mechanical characteristics

A strengthened glass sheet product as well as a process and an apparatus for making the product. The process comprises cooling the glass sheet by non-contact thermal conduction for sufficiently long to fix a surface compression and central tension of the sheet. The process results in thermally strengthened glass sheets having improved breakage properties.

Thermally tempered glass and methods and apparatuses for thermal tempering of glass

A strengthened architectural glass or glass-ceramic sheet or article as well as processes and systems for making the strengthened architectural glass or glass-ceramic sheet or article is provided. The process comprises cooling the architectural glass sheet by non-contact thermal conduction for sufficiently long to fix a surface compression and central tension of the sheet. The process results in thermally strengthened architectural glass sheets that may be incorporated into one or more panes in single or multi-pane windows.

Thermally strengthened architectural glass and related systems and methods

Methods and apparatus for testing the actual glass parts that are to be used in electronic devices are disclosed. According to one aspect of the present invention, method for qualifying a glass part includes obtaining the glass part, and applying at least one thermal shock to the glass part. Once the thermal shock is applied, it is determined if the glass part qualifies for use in a device, e.g., a portable electronic device. If it is determined that the glass part qualifies for use in the device, the glass part is identified as qualifying for use in the device.

Thin dicing glass article

A process for the thermal tempering of glass wherein the hot glass is immersed in a vessel in which there are two mutually immiscible liquids. The liquid of lower density is above the liquid of higher density. The glass is precooled for a specific time in the liquid of lower density and then is brought into the liquid of higher density.

Process for the thermal tempering of glass

PROCEDE DE TREMPE DE VERRE DANS LEQUEL ON CHAUFFE LE VERRE A UNE TEMPERATURE SUPERIEURE A SA TEMPERATURE DE TRANSFORMATION ET INFERIEURE A SA TEMPERATURE DE RAMOLLISSEMENT PUIS ON LE REFROIDIT BRUSQUEMENT. LE PROCEDE EST CARACTERISE EN CE QUE POUR LE REFROIDIR ON PLONGE LE VERRE DANS UN RESERVOIR CONTENANT DEUX LIQUIDES NON MISCIBLES SUPERPOSES, DE DENSITE DIFFERENTE, EN LE MAINTENANT PENDANT UN TEMPS DETERMINE DANS LE LIQUIDE A MOINDRE DENSITE POUR LE PREREFROIDIR PUIS EN L'INTRODUISANT DANS LE LIQUIDE DE DENSITE SUPERIEURE POUR LE REFROIDISSEMENT FINAL.
