An Automatic Vibroscope

Abstract

A simple, automatic version of the vibroscope now frequently used for the determina tion of mass per unit length of fibers, filaments, and yarn is described. The automatic vibroscope gives continuous indication, is very fast in response, and permits the study of sorption kinetics in single fibers. It is also more sensitive than most manually ad justed versions. Details are given of the construction and operation of the instrument, and an assessment is made of the accuracy of measurement under usual operating condi tions. Some other possible applications are briefly discussed.
