Title: Louis F. Coffin: Innovator in Pipe Defect Detection
Introduction
Louis F. Coffin is a notable inventor based in Schenectady, NY (US). He has made significant contributions to the field of pipe defect detection, holding a total of 5 patents. His innovative methods and systems have advanced the way defects in structures are identified and addressed.
Latest Patents
Coffin's latest patents include a "Method and system for detecting defects in pipes or other structures." This invention teaches a method for rapidly connecting and disconnecting a large number of point contacts onto a pipe surface for defect detection. The system utilizes a plurality of sharply pointed pin contacts that are independently pressed onto the pipe surface by means such as springs. Each pin is connected to a power supply and sensing apparatus, allowing for effective detection of defects in structures like pipes.
Another significant patent is the "Method of engagement of electrical contacts to pipe members." This scheme involves using gas pressure to press sharply pointed pin contacts onto the pipe surface. Each pin is held in a conforming opening in an annular ring structure, which maintains gas pressure to urge the pins against the pipe surface. This innovative approach also connects each pin to a power supply and sensing apparatus, enhancing the efficiency of defect detection.
