Abstract: A fire's electrostatic field is used to directly control and extinguish a fire. A flame is, in and of itself, a virtual electrode. The inventive electro-static fire control and extinguishing device uses at least one common electrode and allows the fire's own electrostatic field to act as the other virtual electrode to repel the fire's flame, controlling the spread of the fire or to control its direction or to totally extinguish it. The electro-static fire control and extinguishing device exploits the electrostatic properties of the fire's flame, directly using at least one electrode set at the appropriate electrostatic charge to create the desired fire control while the fire acts as the second source of the electrostatic field in which the electrostatic attraction/repulsion interaction takes place. A high voltage electrostatic field is produced by a high voltage static generator and the desired charge level is delivered to the flame via a conductive grid.

Abstract: Ground fires are contained by an apparatus such as a brush cutter that creates a fuelbreak. The brush cutter (10) includes a rearwardly positioned tractor (11) and a forwardly positioned cutter assembly (12) for cutting fuelbreaks through brush. The brush cutter renders cut brush into smaller pieces that lay substantially on the ground after cutting and that smolder when ignited while lying on the ground. Outboard rectilinear cutting blades (49 and 51) rotate in their forward arcs toward each other so as to urge the cut brush inwardly toward the adjacent blades for re-cutting. The leading skirt (31) of the cutter deck (30) engages and bends the taller brush in the direction of movement of the brush cutter before the lower portions of the brush are cut, thereby inducing the brush to fall in the path of the brush cutter, so that it is overrun by the brush cutter and chopped. The chopped brush is disposed along the path of cut brush, thereby providing a pathway through the uncut vegetation.

Abstract: A rocket propelled textile and cordage net fire extinguishing system is deployed from a platform at a safe standoff distance from a fire. The rocket propelled matrix-like net flies over, lands on, and drapes over the burning site. A detonating means, or detonating network on the net is actuated to rupture spaced-apart canisters on the net that are filled with halon and/or other fire extinguishing compounds. The detonating network quickly disperses the fire extinguishing compounds to engulf and extinguish the fire safely and efficiently without unduly exposing fire fighters to danger. The net fire extinguisher system can extinguish fires aboard a maritime vessel, particularly when the burning craft cannot be safely boarded or burns so fiercely that it cannot be approached closely. The net fire extinguisher system can combat highly dangerous fires including chemical and oil fires, (oil rig fires) on land and at sea.

It is significant that when a predetermined lowest pressure drop is registered, for the ventilating air in the direction of flow, over a measuring spot at the inlet side or the outlet side, a blocking is effected of the flowing area of the ventilating air past the measuring spot.

Hot combusted gases from the engine are periodically passed through the desiccant chamber and condenser chamber to remove the moisture and regenerate those chambers. Pairs of chambers are preferably provided so that timer controlled valves channel the combusted gases through one set of a condenser chamber and a desiccant chamber while another set of chambers is being regenerated.

Abstract: The present invention contributes a novel device and method of controlling fire growth by diverting the heat release site from the flame zone to an easily extinguishable catalytic surface. The invention introduces a screen or mesh having a catalytic coating into a flame and causes severe flame instability. The catalytic surface of the screen has a significantly lower activation energy than the flame zone. Therefore, upon insertion of the catalytic screen into the flame plume, the heat release site transitions from the flame zone to the catalytic screen, and the glowing surface of the screen replaces the violent fire plume above a burning object. Because the glowing surface is less violent and combustion occurs at a much lower temperature, the fire is prevented from propagating to nearby structures. Further, without the strong buoyancy forces of hot gases rising upward and flame being augmented by crosswinds, the glowing surface of the catalytic screen is readily extinguished.
