Title: Innovations by Robert W. Schrader in Photographic Film Technologies
Introduction
Robert W. Schrader is an influential inventor based in Rochester, NY, who has made significant contributions to the field of photographic films. With a total of 2 patents to his name, Schrader has developed innovative methods that have enhanced the performance and quality of film elements used in various applications.
Latest Patents
Schrader's latest inventions include:
1. **Wrinkle Free Lamination Method for Releasably Laminated, Stretched Webs** - This patent describes a protective web that is releasably laminated to an adhesive-coated stretchable web. The process involves continuously drawing the webs at differential degrees of tensile strain into laminating contact in the nip formed by a resilient and a non-resilient roller. This innovation aims to improve the adhesion and usability of laminated webs.
2. **Process for Reducing Core-Set Curling Tendency and Core-Set Curl** - This patent outlines a process for treating heat-tempered film elements that have a tendency to curl. By heating a core-set-prone thermoplastic polymeric film, such as poly(ethylene terephthalate), under controlled conditions, Schrader’s method effectively reduces the shelf-life core-set curling tendency and core-set curl by as much as 60%. This makes the resulting heat-tempered photographic film particularly suitable for manufacturing low-curl microfiche and amateur movie films.
Career Highlights
Robert W. Schrader is associated with the Eastman Kodak Company, where he has been instrumental in developing advanced film technologies. His work has contributed greatly to improving the quality and reliability of photographic films, addressing critical issues such as curling and adhesion.
