Patent number: 11858843Abstract: A device for annealing glass panes includes rollers for transporting the glass panes and two sets of slit-shaped nozzles, which run parallel to the axes of the rollers and from which cooling air can be directed onto both sides of the glass panes. In the device, cooling air acts as effectively as possible on the two surfaces of the glass pane, and anisotropies and stresses within the glass are reduced. This can be achieved by each nozzle being formed as a continuous flow channel, which extends over the width of the glass panes and on both parallel running sides of which partitions are arranged, for the forming of a flow pocket assigned to this flow channel. The cooling air that comes back from the glass panes is returned between this flow channel and the associated partitions.Type: GrantFiled: July 31, 2019Date of Patent: January 2, 2024Assignee: sedak GmbH & Co.

Publication number: 20100024485Abstract: The conservation of energy in the glass industries via the use of heat shields to decrease the amount of energy lost during transportation from the forming process to the annealing process. For maximum effectiveness, the thermal shields are made of materials whose surface has an emissivity of, but not limited too, less than 0.3. They are mounted from, or adjacent to, the means of conveyance of the glass material such that their use will not prohibit the normal production of such glass product. Their installation shall include the means for quick removal or relocation in case of production upsets. The heat shields reflect the radiant energy that is emitted from the high temperature glass back onto itself, and adjacent products, in a manner such as to reduce the loss of energy from such product that may subsequently be necessary for the annealing process.Type: ApplicationFiled: July 30, 2009Publication date: February 4, 2010Inventor: William Stuart Duerk

Patent number: 7554629Abstract: A method of manufacturing a microlens substrate having a plurality of microlenses includes the steps of: preparing a substrate having two major surfaces and a plurality of concave portions formed in one of the two major surfaces, each of the concave portions having a shape corresponding to that of each of the microlenses being formed in the one of the two major surfaces of the substrate; preparing a base material substrate formed of glass having a transformation point lower than that of a constituent material constituting the substrate; and pressure-joining the substrate to the base material substrate in a heating state. In the pressure-joining step, the substrate is joined to the base material substrate and the concave portions fill with the glass material of the base material substrate which is melted by the heat.Type: GrantFiled: April 26, 2006Date of Patent: June 30, 2009Assignee: Seiko Epson CorporationInventors: Nobuyuki Miyao, Mitsutoyo Tanaka

Publication number: 20090100873Abstract: Methods of drawing glass sheet via a downdraw process are provided. In certain aspects, the methods utilize rapid cooling below the root (70) of the forming apparatus (10). Such rapid cooling can, for example, facilitate the use of glass having a liquidus viscosity less than about 100,000 poise. In other aspects, the methods utilize slow cooling between the viscosities of 1011 poises and 1014 poises. Such slow cooling can facilitate the production of glass substrates which exhibit low levels of compaction. In further aspects, substrates are removed from the glass sheet at elevated temperatures which can facilitate increases in the production rates of downdraw machines. In still further aspects, rapid cooling below the root, slow cooling between the viscosities of 1011 poises and 1014 poises, and/or substrate removal at elevated temperatures are combined. Such combinations can facilitate economically effective utilization of downdraw equipment.Type: ApplicationFiled: July 21, 2006Publication date: April 23, 2009Inventors: Douglas Clippinger Allan, Olus Naili Boratav, Andrey V.
