Title: Innovations of John P O'Brien

Introduction

John P O'Brien is a notable inventor based in Pawcatuck, Connecticut. He holds a total of 5 patents that showcase his contributions to the field of shock tube technology and safety systems. His innovative designs have significantly advanced the capabilities of signal transmission and detonation systems.

Latest Patents

One of his latest patents is the Signal Transmission Fuse. This invention features a small diameter shock tube with a unique internal surface configuration. The design allows for a higher powder loading per meter of tubing compared to conventional shock tubes. The tube's outside diameter is less than 0.10 inches, preferably 0.085 inches, and it consists of inner and outer layers made from different polymeric materials bonded together through a coextrusion process. The inside surface of the shock tube includes radially inwardly projecting ribs or protuberances, which enhance the internal perphi of the inner surface cross-section, achieving a 30% increase in safety for powder loading per meter.

Another significant patent is the Diode Cutoff and Safe Packaging System for Detonating Cord. This invention involves a block molded from polymeric material that contains a through passageway for percussive shock waves. Angularly related channels connect with the containment passageway to accommodate arcuate segments of detonation cord. The alignment of multiple blocks creates an efficient packaging setup for the cord, allowing a percussive signal traveling along the cord to be short-circuited within the packaging. A diode version of the block can respond to the signal in a specific direction of travel.
