Title: John Christopher Hallahan: Innovator in Gas Flow Technology
Introduction
John Christopher Hallahan is a notable inventor based in San Jose, CA. He has made significant contributions to the field of gas flow technology. His innovative approach has led to the development of a unique system that enhances the efficiency of gas flow management.
Latest Patents
Hallahan holds a patent for a "System and method for dividing flow." This invention provides a solution for dividing a single flow of gas into two or more secondary flows with known, precise values. The system operates without requiring a high upstream pressure, making it both efficient and practical. The design includes an inlet for receiving the single gas flow, along with first and second flow lines connected to the inlet. A mass flow meter measures the gas flow through the first line and provides a signal indicative of the measured flow rate. A restrictor is incorporated to control the gas flow through the first line to a desired flow rate, ensuring optimal performance of the mass flow meter while maintaining a lower pressure than a predetermined upper limit. Additionally, a mass flow controller adjusts the flow rate through the second line based on the signal received from the mass flow meter.
