Title: The Innovations of Ernest Arthur Sexton
Introduction
Ernest Arthur Sexton is a notable inventor based in St. Catharines, Canada. He holds three patents that showcase his contributions to the field of paper processing and treatment. His innovative approaches have significantly impacted the efficiency of waste paper recycling.
Latest Patents
One of Sexton's latest patents focuses on ink removal from waste paper. This process treats waste paper, particularly newsprint, to release adhering ink particles from the paper fibers. The ink solids and organic contaminants are preferentially collected on the surface of inserted non-soap solids, which have an affinity for the ink solids and are larger in size. The ink-coated solids can then be removed from the system using physical means such as hydrocyclones, screens, or decantation. Another significant patent involves a process for treating a slurry of cellulosic material. In this method, a slurry is diluted to a flowable consistency and subjected to a pressure differential on a permeable surface. This process increases the slurry consistency and forms a mat of cellulosic material on the surface. The liquid and solids that pass through the permeable surface are recycled for use as slurry diluent, while the mat remains on the surface and undergoes treatment in multiple stages.
