摘要： A thickness of at least one preselected portion of a substrate, such as glass substrate for example, is controlled. A laser beam is directed to the at least one preselected portion of the substrate in a viscous state, thereby increasing a temperature and reducing a viscosity of the at least one preselected portion of the substrate in a viscous state sufficiently to cause the at least one preselected portion of the glass substrate to attain a desired thickness. The laser beam after it is generated can be directed to a reflecting surface from which the laser beam is reflected to the at least one preselected portion of the substrate in the viscous state. The substrate can comprise a glass ribbon produced in a downdraw glass forming process for example, and the laser beam can be directed onto a plurality of preselected portions of the glass ribbon.

摘要： A float glass process for production of high melting temperature glasses utilizes a binary metal alloy bath having the combined properties of a low melting point, low reactivity with oxygen, low vapor pressure, and minimal reactivity with the silicate glasses being formed. The metal alloy of the float medium is exothermic with a solvent metal that does not readily form an oxide. The vapor pressure of both components in the alloy is low enough to prevent deleterious vapor deposition, and there is minimal chemical and interdiffusive interaction of either component with silicate glasses under the float processing conditions. Alloys having the desired combination of properties include compositions in which gold, silver or copper is the solvent metal and silicon, germanium or tin is the solute, preferably in eutectic or near-eutectic compositions.

摘要： A pair of glass ribbon edge detectors each have a power source connected to a carbon probe suspended over the molten metal bath of a glass forming chamber and to the molten metal bath to form a pair of capacitors. The voltage output of each capacitor has a first value when the probe is over the molten metal bath, a second value when the probe is over the glass ribbon and a third value when the probe is over a portion of the molten metal bath and a portion of the glass ribbon edge. Displacement and direction of displacement of each probe is used to determine glass ribbon width.A tweel for metering glass onto the molten metal bath has linear displacement gauges mounted at each side thereof and directly connected to the tweel so as to monitor displacement of the tweel to determine the flow of molten glass into the forming chamber. Movement of the tweel in response to the capacitors' output controls the flow of molten glass to control the ribbon width.

摘要： An apparatus for manufacturing flat glass wherein a pool of molten metal is provided for supporting the glass during its manufacture is provided with a molten glass delivery facility that includes a refractory glass supporting member that extends into contact with the molten metal upon which the glass is to be delivered and formed. The refractory that contacts the molten metal is a gas impervious refractory, preferably a glass phase refractory, that permits the direct delivery of molten glass from the refractory support onto the molten metal while avoiding the introduction of fine seeds or bubbles into the glass.

摘要： A flat glass manufacturing apparatus is disclosed which comprises a glass melter and molten glass conditioner connected to a forming chamber which contains molten metal on which a continuous sheet of flat glass may be formed. The molten glass conditioner is connected to the forming chamber by a molten glass delivery means which includes a convex threshold over which the molten glass flows onto the molten metal. Molten glass contact with the threshold member is minimized in that most of the glass entering the forming chamber has not contacted the threshold member and that which has moves relatively slowly in comparison to the general flow of molten glass over the threshold member.

摘要： An apparatus for mounting a threshold in communication with a glass forming chamber containing molten metal includes a supporting structure and tension members for drawing the threshold against both the supporting structure and the inlet end of a glass forming chamber. The apparatus may also include outboard compression members for urging side members or jambs inwardly against the threshold. The entire assembly is easily removable for repair or replacement, yet a glassmaking apparatus including it is not subject to loss of molten metal due to separation of the threshold from the forming chamber during use.

摘要： Molten glass is poured on to a bath of molten metal to form a pool of molten glass on the bath, which pool is held back on the bath surface by an elongate member which can be solid, wetted by the glass, extending across the downstream end of the pool. A ribbon of glass is drawn from a forward flow of molten glass beneath the member and the ribbon is rapidly cooled to stabilize its dimensions as it is drawn away from the member. The glass is heated in the region of the member to maintain forwardly flowing glass in that region at a viscosity which is lower than the viscosity of molten glass of the pool upstream of the member but at viscosity at which the glass also wets on to the member. The ribbon is drawn from the lower viscosity, forwardly flowing glass. The method is suitable for the production of flat glass of thickness in the range 0.5 mm to 10 mm; also the production of glass foil of thickness in the range 0.005 mm to 0.5 mm.

摘要： In the manufacture of float glass, the width of the glass formed in controlled by detaching the width of the ribbon after it is substantially cooled and attenuated, and employing the error of the detected width from the target width to control the target width of the ribbon at a point upstream in the process where the ribbon is hot and acting as a viscous liquid, by detecting the width of the ribbon at the upstream point and employing the error that detected width from its target width to control the target position of a tweel or gate controlling the flow of molten glass in the float bath and controlling the tweel to ultimately control final ribbon width in a stable manner.
