METHOD OF TEMPERING GLASS SHEET BY QUENCHING

Glass toughening quench system

The air quench system described is a system to provide large volumes of high velocity air directed onto the surfaces of sheet glass to rapidly cool and thus toughen the glass. This is achieved by the use of specially designed compressed air ejectors fitted in manifolds. Compressed air escapes at very high velocity into the throat of the nozzles, and draws into the nozzle cap a much larger volume of atmospheric air. This provides the high volume of quenching air directed onto the glass surfaces. ...

HEATING GLASS SHEETS

A method of heating a glass sheet which is moved on a conveyor which contacts one face of the sheet. In order to reduce the contact between the contacted surface of each glass sheet and to keep the leading edge of each sheet clear of the conveyor, anticlastic bending of the sheet is caused, and the stable anticlastic shape of the sheet is determined such that the sheet is arched away from the conveyor transversely of the sheet with respect to the conveying direction and with the sheet having a reverse curvature along its longitudinal extent so that the leading and trailing edges of the sheet are bent away from the conveyor. Anticlastic bending of the sheet is caused by producing a temperature differential between the central area and at least a part of the periphery of the sheet, for example, by heating said part of the periphery.

Preventing gas from occupying a spray nozzle used in a process of scoring a hot glass sheet

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. This cools the quenching liquid passing through the nozzle, and increases the solubility of bubbles in the quenching liquid in the nozzle. A gas filter can receive gas-rich quenching liquid from the pressurized quenching liquid source, remove gas from the liquid, and send gas-depleted quenching liquid to the spray nozzle.

Preventing gas from occupying a spray nozzle used in a process of scoring a hot glass sheet

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. This cools the quenching liquid passing through the nozzle, and increases the solubility of bubbles in the quenching liquid in the nozzle. A gas filter can receive gas-rich quenching liquid from the pressurized quenching liquid source, remove gas from the liquid, and send gas-depleted quenching liquid to the spray nozzle.

Movement of glass sheets using hoisting jet nozzle and switching operations

FIELD: chemistry. SUBSTANCE: invention relates to a method of switching between operations for moving glass sheets during cyclic moulding of a first and a second glass sheet. The glass sheets are moved through cyclic transportation on a roller conveyor over an assembly of hoisting jet nozzles. Gas can be moved upwards through the nozzle under pressure for upward movement of a glass sheet from the roller conveyor to the bottom surface of the top support lying over the roller conveyor. Stoppers are inserted into those hoisting jet nozzles which do not require supply of gas under pressure in order to move the glass sheets of the first shape upwards. Stoppers can also be removed from closed hoisting jet nozzles which require supply of gas under pressure in order to move second glass sheets upwards. EFFECT: reduced expenses during glass production and reduced time consumption during cyclic movement of heated glass sheets of the chosen shape. 16 cl, 6 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 393 123 (13) C2 (51) МПК C03B 35/24 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21), (22) Заявка: 2008120682/03, 24.10.2005 (24) Дата начала отсчета срока действия патента: 24.10.2005 (43) Дата публикации заявки: 10.12.2009 (72) Автор(ы): ЛЕВАНДОВСКИ Трой Р.

Spray nozzles are used in the process of cooling a hot glass sheet during a laser scoring process or other high energy glass heating process. The scoring is done by a high energy means such as a laser. The spray nozzle is located in proximity to the glass sheet that creates the gas in the liquid (e.g., water) used to cool the glass located in the nozzle. The gas (e.g., air bubbles) is removed from the cooling liquid. Next, the spray nozzle is used to spray the cooling liquid onto the glass sheet at the position where the laser advances the sheet scoring sheet, such as using a movable anvil machine at the bottom of the draw. The spray nozzle (purge nozzle) has a purge opening and tubing connected to the discharge position. The purge nozzle may have a sloped passageway through which the pretreatment gas bubbles near the purge opening of the nozzle. The spray nozzle may include a cooling coil passing around a nozzle passage that can move the coolant along the coil. This cools the cooling liquid passing through the nozzle and increases the solubility of the bubble in the cooling liquid of the nozzle. The gas filter receives a gas-rich cooling liquid from a pressurized cooling liquid source, removes gas from the cooling liquid, and sends a gas-depleted cooling liquid to the spray nozzle.

Moulding/tempering glass sheets - of less than equilibrium thickness

Moulding/tempering of glass sheets of less than equilibrium thickness i.e. the thickness to which it will spread under the sole influence of its surface tension and gravity on a non-wetted surface, by (a) periodically introducing a suitable volume of molten glass into the cavity of a mould, not wetted by molten glass and with dimensions and shape as required for the finished sheet and which is placed in an enclosure heated to the temp. of molten glass, (b) modifying the shape of this volume of glass by a forming tool so that it covers the bottom of the mould and is in continuous contact with the surrounding lateral surfaces, in such a way as to create a pre-form, thinner in its central zone and thicker in its marginal zones than the molten sheet to be produced, (c) simultaneously withdrawing the forming tool and establishing a gas pressure above the liquid glass pre-form above atmospheric and such that the sheet of motel glass can be in equilibrium while covering the bottom of the mould, (d) hardening (solidifying) the molten glass sheet to fix its thickness and finally transferring the hardened sheet to another compartment in which it is energetically cooled to ensure that it is tempered.

Toughening large panes of glass - using groups of air-jets supplied by independently- controlled wind boxes (BE050476)

Device for the rapid cooling of large glass panes using air-jets to achieve thermal pre-stressing, using two wind boxes facing each other and fitted with front plates provided with numerous projecting blowpipes. Each box is divided into at least three separate chambers by walls located at 90 degrees to the front plate, and the press. of the air, which is above atmos. press. in each chamber, can be independently controlled. The wind boxes may consist of a middle chamber surrounded by four separate and independently-controlled chambers, and each chamber may be provided with one or more separate air inlets with flap valves. Used for toughening large panes of glass, e.g. where the front plate of the wind boxes must exceed 10m2.
