Title: Richard C. Progelhof: Innovator in Thermoset Materials and Optical Fiber Manufacturing
Introduction
Richard C. Progelhof is a notable inventor based in Berkeley Heights, NJ (US). He has made significant contributions to the fields of thermoset materials and optical fiber manufacturing. With a total of 2 patents, his work has had a lasting impact on these industries.
Latest Patents
One of Progelhof's latest patents focuses on the molding of thermoset materials. Various methods have been proposed for measuring the viscosity of thermosetting polymers, but these methods are generally inaccurate. Progelhof proposes a test that avoids the inaccuracies of previous techniques. 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.
Another significant patent by Progelhof pertains to an optical fiber manufacturing technique. 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. This stripping is periodically repeated to ensure that the entrained flow is not re-established, enhancing the overall efficiency of the process.
