Inventors
The first patented detonation flame arrester was developed by Nicholas Roussakis et al., U.S. Patent 4,909,730 and was issued in March 20, 1990. Its need was initially driven by new environmental legislation, namely the Clean Air Act of the USA. Regular flame arresters had been around for years, but they had very limited applications.
There have been at least a dozen more since then. A few are as follows;
- Nicholas Roussakis & Dwight E Brooker, U.S. Patent 5,415,233 issued May 16, 1995
- Dwight E Brooker, U.S. Patent 6,644,961 issued Nov 11, 2003
- Dwight E Brooker, U.S. Patent 6,699,035 issued Sept 6, 2004
- Dwight E Brooker, U.S. Patent 7,056,114 issued June 6, 2006
