Abstract: A system for fighting a fire includes a plurality of containers containing liquid nitrogen. Thermally activated release mechanisms are each connected to one of the containers. Each thermally activated release mechanism is configured to release the liquid nitrogen from a connected container when a predetermined safety threshold temperature is reached, so that the released liquid nitrogen produces an expanding volume of cold nitrogen vapor. A central storage container stores liquid nitrogen. The central storage container is connected to each of the plurality of containers. A sensor system activates refilling of a respective container with liquid nitrogen from the central storage container when the amount of liquid nitrogen in the respective container is below a predetermined threshold.

Abstract: A device for and method of using the device to dispense pourable material from one or more pouches is provided. The device comprises a pair of hinged plates between which one or more pouches can be positioned. The plates of the device are joined by a ratcheting element that secure the plates and any pouches positioned between them. When a squeezing force is applied to the plates, the plates exert pressure upon the one or more pouches to cause the contents of the pouch(es) to be expelled. The ratcheting element is adapted to adjust automatically in response to the force exerted upon the plates. A device adapted to heat and dispense the contents of the one or more pouches is also provided.

Disposed within the discharge head is a plunger member configured to be retained within the discharge outlet, and a heat sensing element which is adapted to release the plunger element from the discharge outlet when a fire is detected. Once the release plunger is released from the discharge outlet, the fire-extinguishing agent exits the container body through the discharge valve and through a sprinkler head onto the fire emanating from the stove top.

Abstract: A fire-extinguishing bomb that can be pre-programmed to explode 2-200 feet above the ground or tree line. The bomb employs a laser or barometric altitude sensor in combination with a GPS-altitude sensor for failsafe detonation with extreme accuracy at the proper altitude. The redundant failsafe altitude-dependent detonation system ruptures a container carrying a payload of wet or dry fire retardant/suppressant, preferably dry environmentally-friendly fire-retardant powder having no toxicity and having fertilizer properties. Upon detonation the device coats the ground below with a uniform fire extinguishing coating. The core components of the bomb can be biodegradable, or alternatively can be readily retrieved and reused after each activation, thereby increasing both economy and reducing environmental concerns.

Abstract: The fire extinguishing ball includes an outer ball cage, an inner ball cage freely rotatable within the outer ball cage about one axis, and an internal fire extinguishing assembly carried by the inner ball cage and freely rotatable therein about a different axis. The internal fire extinguishing assembly includes a hollow ball-shaped body containing compressed gas and fire extinguishing agents. A valve assembly attached to the top of the body permits refilling of the body and dispersion of the contents during operation. The internal fire extinguishing assembly is connected to the inner ball cage so that the valve assembly will be disposed on top when the fire extinguishing ball is at rest. The ball can be tossed or rolled towards fires in difficult to reach areas. Exposure to heat opens the valve in the valve assembly to thereby disperse the contents of the body and extinguish the flames.

Abstract: The object of the inventive method and device for controlling and/or extinguishing fires is to extend the range of means for transporting devices to a fire site, substantially reduce the time for the operating preparation thereof and to exclude a fragmentation field caused by the device explosion which ensures the momentary conversion of a fire-extinguishing composition into a fine cloud associated with a simultaneous airblast effect produced to a fire area and a maximum distribution of said fire-extinguishing composition through the fire volume. Said method for controlling and/or putting out a fire consists in effecting the fire area by an airblast and the high-speed flow of the air-dispersed mixture of the fire-extinguishing composition (7) produced by the explosion of a fire-suppressing device (2) which comprises a dispersing charge (8) and a container (6) with the fire-extinguishing composition (7).

Abstract: A device and a method for explosive quenching of fires are indicated, for example forest and area fires. The quenching device contains two flexible hoses (1, 2) disposed next to one another and transversely to the direction of risk (5), and closable at both ends, for accommodating quenching agents, and in each case an explosive (3, 4) in or on the hoses (1, 2) atomizes the quenching agent by its ignition to form a mist, which is applied to the fire. In order to achieve a directed ejection of the quenching agent in the direction of the area of risk, the pulse (I.sub.1) which emerges from the first hose (1) facing way from the area of risk is greater than the pulse (I2) emerging from the second hose (2) facing the area of risk. For differing hose diameters, dimensioning of the quantities of explosive in relation to the diameter of the associated hose is effected taking into account the density (of the quenching agent according to a formula according to the invention.
