Abstract: A system and method for extinguishing fires is provided which includes applying an aqueous solution of a gel-forming material to structures in an area to be protected and separately applying an aqueous solution of a gel-inducing material to the same structures so that the solutions will mix and form a blanket of gas impervious aqueous gel which flowingly envelopes the structures and tends to smother any fire therein. The preferred gel-forming material is polyvinyl alcohol and the preferred gelinducing material is borax.

Abstract: An injection apparatus for introducing a slurry of water swellable gelling agent into a water line feeding a fixed fire extinguishing system to form an ablative extinguishant therein. The apparatus includes a peristaltic pump driven by a hydraulic motor using water at line pressure for motive fluid and controlled by a servomechanism driven in part by a flow sensor to ensure injection rates corresponding to flow rates of water in the line. The injection apparatus is operated in a no-injection failure mode to avoid interference with normal flow of plain water to the fire extinguishing system.

Abstract: A pressure responsive discharge head wherein an expellable plug is disposed in the outlet of a body member having an inlet adapted for connection to a source of extinguishant. A magnetic assembly applies a magnetic force to retain the plug in the outlet in the absence of a predetermined fluid pressure in the body member sufficient to overcome the magnetic force.

Abstract: A system and method for fluid flow control in which a valve located in a main supply conduit for the fluid is biased open to permit fluid flow through the conduit. An actuator moves the valve to and maintains it in a closed position in response to a continuous dynamic energy input, the cessation of which permits the valve to move to its normal open position.

Abstract: A method of fire protection in which extinguishant is delivered to a plurality of discharge heads located in the space to be protected from fire. The number of heads that are opened to deliver extinguishant in response to a fire situation is limited to those located in the immediate vicinity of the fire. In this manner the opened heads are not robbed of valuable extinguishant, and water damage to materials located in areas remote to the fire is minimized. A discharge head utilized in the above method.

Abstract: AN INJECTION APPARATUS FOR INTRODUCING AN ADDITIVE INTO A FLUID LINE FEEDING FIXED FIRE EXTINGUISHING SYSTEM TO FORM AN ABLATIVE EXTINGUISHANT THEREIN. A PUMP IS PROVIDED WHICH IS DRIVEN BY A HYDRAULIC MOTOR USING THE FLUID AS A DRIVING MEDIUM, AND A SERVOMECHANISM CONTROLS THE MOTOR TO INSURE INJECTION RATES CORRESPONDING TO FLOW RATES OF WATER IN THE LINE. THE APPARATUS INCLUDES A DEVICE FOR STOPPING THE INCREASE OF THE INJECTION WITH INCREASING FLOW RATES AFTER A PREDETERMINED FLOW RATE IS ATTAINED.
