Title: The Innovations of Neal Roger Langley

Introduction

Neal Roger Langley is a notable inventor based in Midland, MI (US). He has made significant contributions to the field of materials science, particularly in the development of innovative methods and materials. With a total of 3 patents to his name, Langley continues to push the boundaries of technology and engineering.

Latest Patents

One of Langley's latest patents is a method of measuring yield stress. This invention addresses the yield stress of rheologically plastic fluids, such as coatings, sealants, and personal care lotions. The yield stress determines the tendency of these fluids to flow under low gravitational stress. Langley developed an on-line technique to monitor yield stress during processing, which can be instrumental in controlling the slump or non-slump behavior of these products. Additionally, he has created a method to measure residual stress after a flow excursion returns to zero shear rate, which is related to yield stress and can be used for process monitoring.

Another significant patent by Langley involves polymer-derived ceramic fibers with improved thermal stability. This invention pertains to ceramic fibers of the Si-C-N-O series, which have a diameter of less than about 20 micrometers. Langley discovered that minimizing the impurity content, particularly metals or metallic compounds, enhances the thermal stability of these fibers. The result is that fibers with low levels of contaminants can retain over 60 percent of their initial tensile strength when exposed to high temperatures of 1300-1400°C for at least 30 minutes in a non-oxidative environment.
