| 20080289364 | Method and system for preheating glass batch or ingredient(s) - The invention includes a method and system for heating one or more ingredients of a glass batch or the entire glass batch that is then used to make molten glass using waste hot gases from a system for generating electricity using a drive for an electrical generator that is powered by a heat engine that exhaust waste hot gases having a temperature of at least about 200 degrees C. At least a portion of the electricity generated can be used to power manufacturing plant equipment and the waste hot exhaust gases exhausted by the heat engine, such as a gas turbine, is used in a static or dynamic heat exchanger to heat the entire glass batch or one or more of the ingredients of the glass batch, prior to feeding the glass batch into a glass melting furnace. | 11-27-2008 |

| 20120247152 | PROCESS FOR PRODUCING CHEMICALLY STRENGTHENED GLASS - The present invention relates to a process for producing a chemically strengthened glass, which includes conducting a sampling inspection including a measurement of a refractive index distribution of a glass. According to the process of the invention, the surface compressive stress and the depth of the compressive stress layer of the chemically strengthened glass can be stably and accurately measured. | 10-04-2012 |
| 20120291489 | METHOD FOR MONITORING GLASS MELTING FURNACE, METHOD FOR CONTROLLING INTRODUCTION OF RAW MATERIAL, AND DEVICE FOR CONTROLLING INTRODUCTION OF RAW MATERIAL - Method for monitoring molten state of a glass batch charged into a melting bath of a glass melting furnace, and a method and control device for controlling an amount of a glass batch to be so charged. Regions to be measured are set in regions corresponding to particular partial regions on an image obtained by capturing an image of a liquid surface of the bath to be monitored using a camera. The occupying ratio of an area occupied by image portions representing unmolten glass batches in each region, and a distribution state of the batches in the partial region is recognized from the measured value of the occupying ratios so as to determine whether the molten state quality of the batch is favorable. When the determined quality is not favorable, the amounts thereof to be charged by batch chargers are controlled so that appropriate distribution states can be obtained. | 11-22-2012 |
| 20130167587 | FEEDING DEVICE FOR GLASS MELTING INSTALLATIONS - A feeding device for introducing particulate feedstock into glass melting installations, comprising pushing conveyors supplied by storage containers via guiding channels and directed onto the melt surface, and comprising a slide for advancing the feedstock on the melt surface. To largely avoid asymmetric material and temperature distribution and movements transverse to a feedstock transporting direction, and exposure of the installation mineral construction materials to changing thermal loads, a) at least three pushing conveyors are arranged alongside one another and, in the region of the guiding channels, are arranged so closely alongside one another that they can be supplied by a common distributing device, and are separated from one another in the intermediate region between two guiding channels by a dividing edge, and b) a linkage for the drive of a slide that can be introduced into the glass melt is led through the spacing between each two guiding channels. | 07-04-2013 |
| 20130180287 | METHOD AND APPARATUS FOR FEEDING PREHEATERS FOR GLASS MELTING INSTALLATIONS - A method and an apparatus for feeding preheaters having heating elements for the feedstock of glass melting installations. In order to distribute the feedstock in an extremely thin, but uniform layer thickness on and between the upper heating elements, thereby effectively suppressing or avoiding agglutination of particles and accumulation of the feedstock, a distributor device is arranged above the topmost heating elements including at least three pivotable distributor plates, the pivoting axes of which run in the horizontal edges of a virtual prism. The topmost distributor plate throws the feedstock alternately onto one of the distributor plates arranged underneath, which throws the caught feedstock to one of its sides sternwards. The movements of the distributor plates are controlled by sensors with an evaluation and control circuit and actuators assigned to the distributor plates with the aim of a uniform area distribution of the feedstock over the cross section of the preheater. | 07-18-2013 |
| 20130199240 | METHOD AND SYSTEM FOR DEWATERING AND PREHEATING MIXTURES FOR GLASS MELTING PLANTS - A method and a system for thermal dewatering and preheating aqueous mixtures for feeding glass melting plants when passing through a shaft-like container provided with heating elements disposed one above another in tiers. To avoid the feed material from becoming glued together or agglomerating in the preheaters while the feed material is heated by exhaust gases with separately guided exhaust gases and feed material, a) the uppermost tier heating elements are closed relative to the mixture and are kept above 100 C, b) the interface between the mixture and the atmosphere above the mixture is shaped and heated by the uppermost tier heating elements so that part of the thermal output is emitted to the atmosphere via the mixture, and c) as the mixture proceeds through the container it is heated by further heating elements to temperatures close to the glass melting plant feeding temperature. | 08-08-2013 |
| 20130283858 | TITANIA-DOPED QUARTZ GLASS AND MAKING METHOD - Methods for selecting titania-doped quartz glass which experiences a reduction in OH group concentration of less than or equal to 100 ppm upon heat treatment at 900° C. for 100 hours as suitable material for the EUV lithography member. | 10-31-2013 |
| 20140130547 | METHOD FOR PRODUCING MOLTEN GLASS, AND METHOD FOR PRODUCING GLASS PRODUCT - To provide a method for producing molten glass, whereby formation of dust can be suppressed when the molten glass is produced by an in-flight melting method. Granules containing silica sand and satisfying the following conditions (1) to (3) are used. (1) In a particle size distribution curve obtained by measuring the granules passed through a sieve having 1 mm openings by a dry laser diffraction scattering method, D50 representing the cumulative volume median diameter is from 80 to 800 μm. (2) The average particle size of the silica sand in the granules is from 1 to 40 μm. (3) In a particle size distribution curve obtained by measuring water-insoluble particles to constitute the granules by a wet laser diffraction scattering method, the ratio of D90/D10 is at least 10. | 05-15-2014 |
