Title: Innovations of Steven J Graham

Introduction

Steven J Graham is a notable inventor based in Fairlie, GB. He has made significant contributions to the field of pyrotechnics, holding a total of five patents. His work focuses on enhancing the reliability and efficiency of ignition devices.

Latest Patents

One of his latest inventions is a pyrotechnic ignition device. This device comprises a hollow tubular coiled charge of pyrotechnic sheet material that defines an ignition initiation position. The internal diameter of the charge decreases while the wall thickness increases over a portion of the charge extending from the initiation position in the direction of burning. This configuration enhances the reliability of ignition and the rate of flame development. The adjacent plies of the coiled charge are preferably spaced apart. Additionally, the coiled charge has a portion downstream from the initiation position that decreases in external diameter and wall thickness, which enhances the speed and violence of burning of a main gas-generating propellant charge ignited by the coiled charge. The pyrotechnic sheet material used in this invention comprises a substrate of oxidizing polymeric film coated with an oxidizable metal, such as magnesium.
