Title: Innovations of Gary L Driscoll

Introduction

Gary L Driscoll is a notable inventor based in Boothwyn, PA (US), recognized for his contributions to the field of synthetic materials. He holds a total of 10 patents, showcasing his innovative spirit and dedication to advancing technology.

Latest Patents

Driscoll's latest patents include a process for making synthetic paper pulp. This innovative method involves preparing synthetic thermoplastic polymer fibers by extruding a foamed fibrillated sheet of a normally solid synthetic thermoplastic polymer. The process includes attenuating the molten foamed sheet during extrusion and applying cutting or shearing actions to break it down into short fibers containing numerous fibrils. The polymers used in this process include polypropylene, polyethylene, or a mixture of polystyrene and polypropylene or polyethylene, with the mixture containing more than 40 weight percent of the polyolefin. These short fibers can be blended with natural pulp, allowing for the creation of a coarse paper that can be formed into a final product through heat and pressure, resulting in superior properties.

Another significant patent involves additives to improve the wettability of synthetic paper pulp. In this process, synthetic paper pulp is prepared by extruding a foam sheet of a synthetic thermoplastic fiber-forming resin, which contains from 0.1 to 5.0 wt. % of a soap such as aluminum stearate. The foam sheet is then attenuated and subjected to heat or shearing action to break it down into short fibers. This pulp can be used directly or blended with natural pulp, leading to the formation of a coarse paper and a final product through heat and pressure application. The soap enhances the wettability of the resulting fibers.
