INTERCEPTOR

Dust explosion protection systems, namely, indoor flameless explosion venting and suppression devices comprised of metal pipes or tubes containing gas flow obstructions to quench and release blasts of expanding gases and flames for safer exhaustion

Dust explosion protection systems consisting of automatic isolation valves for closing pipes between chambers upon detection of explosions and automatic explosion suppression, and chemical isolation devices for delivery of dry chemical extinguishing agents into developing explosions, consisting of cartridges for containing an explosion extinguishing agent, cannon barrels for propelling the explosion extinguishing agent into developing explosions, electrically-ignited actuators for loosening explosion extinguishing agent and/or providing accelerating forces to the explosion extinguishing agent as it leaves the cannon, pressurized tanks for adding pressurized gas to the accelerating force of the actuators, and associated power supplies, monitors, pressure sensing devices and switches, and detector interfaces and controls, all sold as a unit
