Roy F Parsons, Deceased

Title: Roy F Parsons: Innovator in Leak Testing Technology

Introduction

Roy F Parsons was a notable inventor known for his contributions to leak testing technology. He was based in Dunstable, MA (US) and held a patent that significantly advanced the field of hermetically sealed parts testing. His work has had a lasting impact on the industry, particularly in the use of helium spectrometers for leak detection.

Latest Patents

Parsons was awarded a patent for a "Sealed parts leak testing method and apparatus for helium spectrometer." This innovative method involves testing small, hermetically sealed pans after exposing them to a trace gas environment, such as helium. The process is designed to identify both gross and fine leaks in the pans, ensuring their integrity. The non-helium expansion technique, used alongside a helium mass spectrometer leak detector, allows for reliable testing by a single apparatus. The test pan is placed in a sealed fixture, and the pressure in an expansion chamber is measured to determine if there are any leaks.

Career Highlights

Throughout his career, Roy F Parsons worked at Varian Associates, Inc., where he developed his patented leak testing technology. His innovative approach to leak detection has been instrumental in various applications, enhancing the reliability of hermetically sealed devices.

Collaborations

Parsons collaborated with notable coworkers, including David G Mahoney and Glenn E Ruiz, who contributed to the development and refinement of his testing methods.

Conclusion

Roy F Parsons made significant contributions to the field of leak testing technology, particularly through his patented methods for helium spectrometers. His work continues to influence the industry and underscores the importance of innovation in ensuring the integrity of sealed devices.
