He has made significant contributions to railway safety technology, particularly with his innovative slip-slide detector system for railway car wheels. His work is essential in enhancing the safety and efficiency of railway operations.

Latest Patents

Edward A Christianson holds a patent for a slip-slide detector system designed for railway car wheels. This inventive system features a magnetic pulse generator mounted on each axle of a railroad car. The outputs from these pulse generators are fed to a detector that compares the speeds of the axles. When wheel slip is detected, indicated by a pulse count difference between axles, the detector activates solenoid-operated dump valves to increase brake pressure on both axles of the slipping axle truck. Once the axle speed recovers to a non-slipping condition, the dump valves are reset, and brake pressure is reduced. Additionally, the detector circuitry can detect wheel slide, allowing for corrective action. The system also includes provisions to prevent synchronous sliding of all axles by sensing the rate of change of count.

Career Highlights

Edward A Christianson is currently employed at Vapor Corp., where he continues to develop innovative solutions for the railway industry. His work has been instrumental in improving safety measures and operational efficiency in railway systems.
