Abstract: A discharge head for fixed fire extinguishing systems of the type in which a fluid extinguishant is supplied under line pressure to a plurality of such heads. The actuation of the head in response to afire is inhibited when line pressure drops below a predetermined magnitude, thereby preserving the ability of already actuated heads in the system to disperse extinguishant directly on a fire. The discharge head operates to release a stream of extinguishant directly on a fire when a predetermined line pressure is present in the head.

Abstract: Imparting a phase change to liquids normally characterized by properties of Newtonian flow and internal convection by converting said liquids to a gel characterized by plastic flow and no internal convection, and exposing said gel directly or indirectly to a heat exchange medium. This method provides essentially instant initial response, minimizes convection losses, and provides phase change without total system involvement.

Abstract: A fire control system in which two fluids are dispensed from two pressurized tanks into a mixing chamber disposed at an elevated position with respect to the floor of the structure to be protected, where they are mixed to form a gel. The gel is continuously discharged from the chamber and forms a gasimpervious sheet extending to the floor to act as a fire barrier.

Abstract: A fluid control system in which a predetermined level of fluid is maintained in a conduit by varying the pressure in the conduit in response to variations in the fluid level. When the fluid level exceeds the predetermined level a powder disposed in a fluid flow relationship with the conduit is wetted by the fluid to produce a gas which causes the pressure in the conduit to exceed the pressure of the fluid, and thus reduce the level of the fluid to the predetermined level. When the fluid level drops below a predetermined level as a result of an increased pressure in the conduit, the conduit is vented to atmosphere to reduce the pressure and raise the fluid level.

Abstract: A fluid control device in which a body member has a passage therethrough extending between an inlet adapted to be connected to a source fluid under pressure and an outlet adapted to be connected to a head for discharging the fluid. A control unit is supported by the body member and includes a movable member normally blocking the passage and having one side exposed to the fluid pressure in the passage. A closed chamber is provided and contains a pressurized gas which normally forces the movable member into the passage blocking position, with the movable member being adapted to move from the passage blocking position in response to the fluid pressure in the passage exceeding a predetermined value sufficient to overcome the force of the pressurized gas in the chamber, to permit the fluid in the passage to flow to the head for discharge.

Abstract: A fire protection system wherein a source of extinguishant is connected to a plurality of high-capacity direct discharge nozzles mounted in an elevated position in the space to be protected. The nozzles are activated in a sequence dictated by their proximity to the fire, with the spacing between the nozzles and the configuration of the extinguishant discharge pattern from each nozzle being such that the operation of each nozzle is independent of the operation of the remaining nozzles. Each nozzle has the capacity to discharge the extinguishant at a rate of no less than one-eighth the total capacity of the system.
