Abstract: The specification describes a process and apparatus for monitoring and controlling the ellipticity of preform tubes during Modified Chemical Vapor Deposition. In response to computer generated signals from the monitoring device, the tube collapse rate is adjusted dynamically by locally changing the temperature of the glass tube, or by changing the physical force acting to collapse the tube.

Abstract translation: 该说明书描述了用于在改进的化学气相沉积期间监测和控制预成型管的椭圆率的方法和装置。 响应于来自监测装置的计算机产生的信号，通过局部改变玻璃管的温度或通过改变用于使管塌缩的物理力来动态地调节管塌陷率。
