The first layer has thickness of 2000-15000 Å and the second layer has thickness of 500-5000 Å, and is thinner than the first. After and/or during heat treatment (e.g., thermal annealing, heat hardening or bending), the protective film is removed. EFFECT: preventing burn-out of the DLC layer on the glass during heat treatment and enabling easy removal of the protective film. 18 cl, 3 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 459 772 (13) C2 (51) МПК C03C 17/34 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2009132524/03, 03.01.2008 (24) Дата начала отсчета срока действия патента: 03.01.2008 (43) Дата публикации заявки: 10.03.2011 Бюл. № 7 (56) Список документов, цитированных в отчете о поиске: US 2005/0048284 A1, 03.03.2005.

Method and apparatus for forming an optical fiber preform by combustionless hydrolysis

The present invention relates to a method and apparatus for fabricating a glass preform used in the manufacture of optical waveguides. The method uses a gas phase flame-free hydrolysis aerosol of a silica precurser without carrier gas and in the substantial absence of combustibles such as CH 4 or H 2 . The flow of the reactants in the reaction chamber is confined and deposited on the target preform by careful control of the thermal profile in the system, namely by providing a thermal gradient in the reaction chamber such that the temperature increases from the inlet to the outlet of the reaction chamber, prior to deposition of the so-formed aerosol on the deposition target.

Method of controlling removal of sheet glass from furnace in process of hardening of sheet glass

FIELD: measurement.SUBSTANCE: invention relates to measurement equipment and can be used for control of sheet glass tempering process. Disclosed is a method of controlling extraction of sheet glass from a furnace in a process of hardening a sheet glass, in which, after the sheet glass is fed into a heating furnace, by means of the monitoring module the operating parameter of the heating elements is monitored in real time and wave filtration of the working parameter of the heating elements is performed. Working parameter of the heating elements passed to the wave filtration is then transmitted to the control module. Control module compares the obtained operating parameter of the heating elements with a given threshold value. When operating parameter of heating elements changes limit value and during further changes again reaches preset threshold value, control module sends command to drive mechanism, and as a result of operation of drive mechanism there is immediate removal of sheet glass from heating furnace or extraction of sheet glass from heating furnace after some time with completion of process of sheet glass heating.EFFECT: technical result is that this invention changes traditional methods of control based on time parameters and allows not only to reduce volume of energy consumption during production of tempered glass, but also to improve quality of finished tempered glass.18 cl, 5 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 737 064 C1 (51) МПК G05D 23/30 (2006.01) C03B 27/012 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C03B 27/012 (2020.08); C03B 27/0417 (2020.08); C03B 29/08 (2020.08); G05D 23/30 (2020.08) (21)(22) Заявка: 2020109890, 11.04.2018 (24) Дата начала отсчета срока действия патента: Дата регистрации: (73) Патентообладатель(и): ЛОЯН ЛЕНДГЛАСС ТЕКНОЛОДЖИ КО., ЛТД.

Glass strengthening and patterning methods

High intensity plasma-arc heat sources, such as a plasma-arc lamp, are used to irradiate glass, glass ceramics and/or ceramic materials to strengthen the glass. The same high intensity plasma-arc heat source may also be used to form a permanent pattern on the glass surface—the pattern being raised above the glass surface and integral with the glass (formed of the same material) by use of, for example, a screen-printed ink composition having been irradiated by the heat source.
