    Abstract: A fire protection system and discharge head utilized in the system in which the head is actuated by a release of a thermal responsive link for permitting extinguishant to discharge from the head. One or more shear pins are provided which connect a cap over the discharge opening of the head, and which are adapted to break in response to a predetermined extinguishant pressure existing in each head to release the cap and allow the head to open. In the event the temperature in the vicinity of the head reaches a predetermined relatively high value, the head will open despite the absence of the above-mentioned predetermined extinguishant pressure.

    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 translation: 一种流体控制装置，其中主体构件具有通过其中的通道，其在适于连接到压力下的源流体的入口和适于连接到用于排出流体的头部的出口之间延伸。 控制单元由主体构件支撑并且包括通常阻挡通道并且具有暴露于通道中的流体压力的一侧的可动构件。 提供了一个封闭的腔室，它包含一个通常会迫使活动件进入通道阻塞位置的加压气体，其中可动件适合于响应于该通道中的流体压力而超过通道阻塞位置超过预定值， 克服室内的加压气体的力，以允许通道中的流体流到头部以便排出。

    Abstract: An apparatus for controlling fluid flow through a conduit, including a housing having an inlet and an outlet adapted to register with the conduit. A valve member is disposed in the housing and is operatively connected to an actuator for moving the valve between an open position in which fluid flow is permitted through the housing and a closed position in which fluid flow through the housing is prevented. The valve is normally urged to the open position and the arrangement is such that a continuous manually applied energy input to the apparatus is required to move the valve to the closed position. A fire protection system incorporating the above apparatus.

    Abstract: A pressure responsive discharge head in which an expellable plug is disposed in the outlet of a body member having an inlet adapted for connection to a source fo fluid, with the plug being connected relative to the body member in a position preventing the discharge of fluid from the outlet. A connector is provided which applies a constant force to the plug to maintain it in the flow preventing position and which is adapted to release the plug in response to a predetermined fluid pressure existing in the body member.

    Abstract: A method for fire protection wherein a nozzle discharges an extinguishant in response to a predetermined fire condition in a manner to create an aspiration effect which circulates the combustion products from the fire in a path including the fire. The circulation of the combustion products is terminated and the rate and manner of discharge of extinguishant from the nozzles can be changed in response to an additional predetermined fire condition.
