    Abstract: A device for cooling sheets of glass by jets of air emitted by at least one nozzle in a form of a pipe, including a box supplying the nozzle with air, airflow ejected via an ejection orifice of the nozzle passing successively through a conical part, of which an internal section is reduced in a flow direction, and then through a cylindrical part including the ejection orifice, of which an internal section corresponds to a smallest internal section of the conical part and to an internal section of the ejection orifice. The cylindrical part of the nozzle has a length greater than 6 times the diameter of the ejection orifice. The device achieves a high level of heat exchange when the sheets of glass are cooled, which makes it possible to increase reinforcing effect on the glass and/or to reduce power of fans used to convey air through the nozzles.

  • Publication number: 20100287991
    Abstract: A spray nozzle is used in a process of quenching a hot glass sheet during a laser scoring process or other high energy glass heating process. The scoring is conducted by a high energy means such as a laser. The nozzle is located in proximity to the glass sheet, creating gas in liquid used to quench the glass located in the nozzle (e.g., water). The gas (e.g., air bubbles) is removed from the quenching liquid. Then, the spray nozzle is used to spray the quenching liquid onto the sheet at a location trailing laser scoring of the sheet, such as using a traveling anvil machine at the bottom of the draw. The spray nozzle (purge nozzle) has a purge opening and tubing leading to a discharge location. The purge nozzle can have a sloped passageway that pre-stages gas bubbles near the purge opening in the nozzle. The spray nozzle can include a cooling coil passing around the nozzle passageway that enables a coolant to travel along the coil.

    Abstract: Methods and apparatus for controlling the stress in, and the shape of, the glass ribbon (15) formed in a downdraw glass manufacturing process (e.g., the fusion downdraw process) are provided. In certain embodiments, the control is achieved by cooling the bead portions (21a, 21b) of the ribbon (15) at a rate which provides a heat flux Q?b at the thickest part of the bead (23a, 23b) which is given by Q?b=Q?q+?Q?, where (i) Q?q is the heat flux at a transverse position adjacent to the bead portion (21a, 21b) at which the ribbon's thickness equals 1.05*tcenter, where tcenter is the final thickness at the ribbon's center line (17), and (ii) ?Q??(tb/tq?1)Q?q+10 kilowatts/meter2, where tb is the thickness of the thickest part of the bead portion. The cooling can take place along the entire length of the ribbon (15) or at selected locations, e.g.

  • Patent number: 7694532
    Abstract: A system and method is provided for tempering a glass container. The method includes the steps of pre-heating the glass container to a first predetermined temperature. The method also includes the steps of applying radio-frequency energy to the pre-heated glass container to heat the glass container to a second predetermined temperature and, after a predetermined amount of time, simultaneously cooling at least one surface of the heated glass container to a third predetermined temperature to treat the glass container. The method further includes the steps of, after a predetermined amount of time, quenching the treated glass container to a fourth predetermined temperature to produce a tempered glass container.

  • Publication number: 20100024485
    Abstract: 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.

  • Patent number: 7554629
    Abstract: 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.

  • Publication number: 20090100873
    Abstract: 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.
