Introduction

Marvin M Christensen is a notable inventor based in Baton Rouge, LA (US). He has made significant contributions to the field of synthetic thermoplastic materials, holding 2 patents that showcase his innovative approaches.

Latest Patents

One of his latest patents is titled "Fusion processing of synthetic thermoplastic resinous materials." This invention describes an apparatus and method for the fusion processing of synthetic thermoplastic resinous materials. It utilizes a first high-velocity stream of gas to transport the resinous material through an elongated passageway, directing the stream of gas and transported material onto a workpiece, thereby fusing the resinous material. The elongated passageway is defined by at least one wall with a plurality of foramina or pores, through which a second stream of gas is directed to heat the resinous material to a fusion temperature. This design also provides a slip stream on the inner surface of the wall, preventing the resinous material from sticking to the surface. The first stream of gas may be heated to initiate or supplement the heating of the resinous material.

Another significant patent is the "Method to fabricate polymeric membranes and diaphragms." This method discloses a process to fabricate shaped membranes or diaphragms with substantially leak-free seams, suitable for use in electrolytic cells to produce a halogen and an alkali metal hydroxide. A preferred polymeric sheet material is formed into a desired configuration, and a fusible substance is placed at or near the edges of the polymeric material prior to applying heat and, optionally, pressure to the fusible substance.
