TREATING SOOT PREFORMS WITH A REDUCING AGENT

A silica soot preform (12) is inserted into a furnace (30). The preform is then treated with heat and carbon monoxide gas (32) so as to reduce impurities that could effect the final product.

METHODS OF AND APPARATUS FOR HEATING GLASSY TUBES

... : A preform tube is caused to be collapsed into a preform rod by causing a heat zone provided by a torch assembly to traverse the tube longitudinally in a plurality of passes. During this so-called collapse mode, a muffle tube encloses that portion of the tube which extends through the torch assembly. Advantageously, the muffle tube projects a predetermined distance beyond one major face of the torch assembly. The torch assembly comprises annular semi-circular end plates and an annular semi-circular center portion having a plurality of exit ports through which gases are directed into engagement with the tube. The center portion is caused to be recessed between the end plates thereby causing the heat zone generated by the gases to be narrowed. The narrowing of the heat zone and the substantial confinement of the heat energy within the muffle tube cooperate with increased gas flow rates to cause the tube to be collapsed in a time period which is substantially less than that achieved by prior ...

Method of reforming hollow class cylinder into rod

Изобретение относится к способу пластического преобразования формы трубчатого полого тела из аморфного вещества в стержень без использования инструмента за счет самопроизвольной усадки. Сущность изобретения заключается в том, что во время самопроизвольной усадки за счет непрерывного откачивания поддерживают пониженное давление по отношению к атмосферному давлению в трубчатой части. Полое тело непрерывно при заданной скорости вращения подводят горизонтально к зоне нагрева и там его вязкость понижают таким образом, что вследствие разности давлений между пониженным давлением и действующим на полое тело наружным давлением полое тело самопроизвольно осаживается в зоне самопроизвольной усадки до образования стержня. Стержень непрерывно при заданной скорости вращения вытягивают из зоны самопроизвольной усадки. Для того, чтобы с помощью такого способа изготавливать за одну рабочую операцию гомогенные стержнеобразные тела, наружные и внутренние размеры полого тела, вязкость стеклянного вещества в зоне самопроизвольной усадки, разность давлений между пониженным давлением и наружным давлением, величину пониженного давления, скорость стягивания стержня и скорость подвода полого тела, а также скорости вращения стержня и полого тела выбирают таким образом, что из зоны самопроизвольной усадки против направления стягивания стержня на оси полого тела образуется штенгель с меньшими размерами поперечного сечения по сравнению с размерами поперечного сечения стержня. 4 з. п. ф-лы, 1 ил.
