Title: Innovations of John S. Piso

Introduction

John S. Piso is a notable inventor based in Framingham, MA (US). He has made significant contributions to the field of measurement technology, particularly in the textile industry. With a total of 3 patents, his work focuses on improving the accuracy and efficiency of yarn measurement processes.

Latest Patents

One of his latest patents is for a moisture corrected denier measurement system. This innovative method utilizes capacitance transducers to automatically correct measurements of yarn denier for moisture content. By testing yarn samples at various moisture levels and frequencies, the system determines the difference in apparent denier outputs between two transducers, which is proportional to moisture content. This difference is then added to one of the measured values to enhance accuracy. Additionally, the method may be further refined using factors derived from the slopes of the curves of transducer output versus moisture and skein denier versus moisture.

Another significant patent by Piso is the finish measuring method and apparatus. This invention determines the amount of electrically conductive finish applied to a filament by measuring its conductance. The measurements are made independently of any differences in conductivity of finish mediums through a reference cell containing a sample of the specific finish medium used. The electric measurement circuit indicates the amount of finish medium on the filament by calculating the ratio of the conductance of the filament to that of the reference cell. This apparatus is designed to be a hand-held device, allowing for practical and efficient use in various applications.
