摘要： The speed at which optical fibers can be drawn and coated is significantly increased by efficiently stripping the gas boundary layer entrained by the moving fiber. The stripping is periodically repeated to ensure that the entrained flow is not re-established.

摘要： Various methods have been proposed for measuring the viscosity of thermosetting polymers. It has been found that these method are generally inaccurate. A test which avoids the inaccuracies of previous techniques is proposed. In this test the heated thermosetting resin is forced at a known flow rate through a runner and through a capillary tube at the end of the runner. By measuring the pressure differential across the capillary a meaningful measure of viscosity is obtained.
