Abstract: An on-off fluid control device in which a body member has a passage extending therethrough between an inlet adapted for connection to a source of fluid under pressure and an outlet adapted to be connected to a head for discharging the fluid. A gate valve is operable to selectively close the passage and open the passage in response to temperature variations occurring in the vicinity of the body member. The gate valve is initially maintained in its open position despite the existence of a temperature corresponding to the temperature that would normally move it to its closed position, to prevent jamming or locking of the valve. An assembly incorporating the control device in combination with a pressure responsive control device and a fire protection system incorporating the control device.

Abstract: A method and apparatus for fighting fire wherein a plurality of extinguishant-discharging heads are supported in an elevated position within the space to be protected and are adapted to discharge the extinguishant in a substantially square pattern over the area to be protected. The heads are arranged in spaced parallel rows with the location of the heads of each row being staggered relative to the location of the heads of its adjacent row, and the diagonal of the square pattern of each head of each row being canted relative to the diagonal of the square pattern of the heads of its adjacent rows.

Abstract: A fire protection system and a sprinkler head utilized in the system, wherein extinguishant is supplied to the sprinkler head which is actuated by a release of a thermal fuse to discharge the extinguishant against a deflector disc and form a hemispherical pattern of droplets. If the fluid pressure in each head does not attain a predetermined value, the head will not be actuated despite release of the thermal fuse.

Abstract: A fire extinguishing sprinkler head for use with a wide range of extinguishants, such as water and hydrolized ablative gel, which has an expellable plug retained in a discharge opening in the sprinkler head by fire-responsive release means. Upon actuation of the release means, the plug is expelled from the sprinkler head by the pressure of the extinguishant to clear the discharge opening of obstacles which could affect the spray pattern of the extinguishant emitted from the sprinkler head. The plug is released at a predetermined inlet head pressure so that the sprinkler head will not provide the extinguishant to the fire at a pressure which will materially affect the spray pattern from the sprinkler head or adversely influence the spray pattern of other sprinkler heads in the system. The sprinkler head also includes means for modulating the flow of extinguishant in response to the inlet pressure of the extinguishant to retain a predetermined extinguishant spray pattern and to maintain the extinguishant supply pressure to the system at a higher level.

Abstract: The application of ablative water in combating fire is improved by wetting the surfaces of the combustible materials to be protected with water containing a surfactant prior to the application of ablative water to such surfaces in order that the subsequently applied ablative water readily penetrates the combustible material down to where the fire is in order that the ablative water be available where it is required.

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.
