  • Publication number: 20110159199
    Abstract: Certain example embodiments relate to an in-line scalable system that may be used in the combustion deposition depositing of thin films. The systems of certain example embodiments may comprise one or more modules, with each such module including at least one burner and at least one high volume cooling section. In certain example implementations, multiple burners and multiple cooling sections are provided to a single module in alternating order. The systems of certain example embodiments may, in addition or in the alternative, comprise a combined flame guard and exhaust system. The combined flame guard and exhaust system of certain example embodiments advantageously may provide a means to reduce the amount of interference of the deposition process by ambient conditions, improve flame uniformity in the deposition zone, contain and exhaust combustion products while reducing restrictions to the stable operating space of the combustion deposition process, etc.

  • Patent number: 4952227
    Abstract: An apparatus for processing glass sheets includes a furnace and a bending station traversed by a conveyor for carrying the glass sheets. A plurality of heaters mounted in the furnace each heat associated areas of the glass sheets in accordance with setpoint temperature signals representing desired values of temperatures for heating associated areas of the glass sheets. One or more parameters of the glass sheets, such as thickness and color, are sensed and the setpoint signal values are changed accordingly. The parameter values are also utilized to change the spacing between the upper and lower mold members in the bending station to adjust the bending pressure applied to the glass sheets. Furthermore, the parameters are utilized to change the speed of the conveyor sections in order to vary the time that the glass sheets are in the furnace and thus the amount of heat imparted to the glass sheets.
