Title: Van B. Johnson: Patent Inventor in Towanda, Pennsylvania

Introduction

Van B. Johnson is an inventor associated with Towanda, Pennsylvania, and E. I. du Pont de Nemours and Company. His patent work includes innovations in daylight x-ray cassette design and materials for preparing surprint proofs. Johnson is credited with 3 patents.

Latest Patents

One of Johnson’s patents describes a daylight x-ray cassette with a movable weight positioned opposite the film entrance slot. When the cassette’s film-holding plates separate, gravity moves the weight to help eject the film, improving the release process.

Another patent covers a process for preparing an improved surprint proof. It uses at least three nonplanar, nonsilver photoimaged elements laminated sequentially onto a specially engineered support. The support’s properties include limited air permeability, strong peel adhesion, and controlled light transmission. These multilayer proofs are intended for pre-press applications.
