Title: Innovations by Charles J North
Introduction
Charles J North is an accomplished inventor based in West Carrollton, OH (US). He has made significant contributions to the field of materials science, particularly in the development of polyethylene castings. With a total of 2 patents, his work has had a notable impact on manufacturing processes.
Latest Patents
One of his latest patents focuses on large void-free polyethylene castings. This innovation involves blending high-density polyethylene pellets with low-density polyethylene powder. The process requires heating the mixture to above the melting point of the low-density polyethylene while remaining below, or only slightly above, the melting point of the high-density polyethylene. This method allows for the incorporation of flame-proofing additives, crosslinking agents, and other materials before fusing. The combination of high-density and low-density polyethylene significantly reduces shrinkage during the cooling process from melting temperature to ambient temperature. The low-density polyethylene must have a sufficiently low melt viscosity to flow under small pressures above the melting temperature.
Career Highlights
Charles J North is associated with Monsanto Research Corporation, where he has been instrumental in advancing polyethylene technology. His innovative approaches have led to improved manufacturing techniques and enhanced product quality.
Collaborations
He has collaborated with Ival O Salyer, contributing to the development of new materials and processes in their field.
