Abstract: A fire protection system which senses the fire and actuates the dispensing of a fire suppressant without the use of electronics or electrical devices. This invention utilizes the process known as occlusion to storage large amounts of hydrogen gas in relatively small confined volumes. When an external heat source is presented to the system, such as that from a fire and/or explosion, the storaged hydrogen--via a metal hydride--is released and thereby builds up a pressure in its confined volume. This pressure is used to do work, namely moving a piston. After the piston moves a predetermined distance, it actuates the release of a gas which in turn fluidizes a dry powder suppressant which is dispensed via hoses and nozzles to the same fire and/or explosion. After the fire is suppressed, cooling of the metal hydride occurs which causes the hydrogen gas to reenter the metal hydride and the pressure in the piston to decrease.

Abstract: A fire detecting and extinguishing apparatus comprises a plurality of detectors mounted above the areas to be protected, a centrally arranged receiver to pick up electric signals or a different frequency from each detector an emitter to which the signals are fed and which diseminates further signals of differing frequencies, and switches each tuned to one of the frequencies of the further signals to receive the further signals from the emitter and solenoids energized by the switches, a platform actuated by each solenoid, a pressurized cylinder, and a valve on the cylinder onto which operates when a weight falls to release a powder or mist from the cylinder to blanket the fire.

Abstract: Apparatus and a method are disclosed for flame-proofing an internal combustion engine by provision of a sensor for detecting the presence of flammable gases in the vicinity of the assembly, a canopy shrouding a hot surface of the engine, and a source of non-flammable fluid operable responsive to signals from the sensor to inject the fluid into the space between the canopy and the said surface, thereby cooling the hot surface and inerting the atmosphere within the canopy.

Abstract: An electrical fire protection system including a plurality of extinguishant filled suppressor units activatable by explosive squibs connected in series. In response to the detection of an abnormal condition associated with fires, a control circuit initiates an activating current flow that detonates the explosive squibs and induces release of the extinguishant from the suppressor units. A supervisory current supply establishes through the series connected squibs, a constant level of supervisory current flow that is insufficient to induce detonation of the squibs but establishes a detectable voltage drop thereacross. In response to the detection of an abnormally high voltage level across the series connected squibs, a switching circuit switches the squibs from a series to a parallel circuit relationship.

Abstract: A fire extinguishing system for use especially on a floating roof tank includes an enclosure secured to the tank roof. The enclosure carries an agent tank, an expellant tank and an accumulator tank. The agent tank contains fire extinguishing agent and includes an expellant inlet and an agent outlet. The expellant tank contains pressurized expellant fluid. An expellant conduit extends from the expellant tank to the inlet of the agent tank. A sprayer duct is connected to the outlet of the agent tank and is arranged along one protected zone of the roof rim. A control valve is disposed in the expellant conduit. A flow control member is disposed in the expellant conduit upstream of the control valve for metering the rate of flow of expellant fluid. The accumulator communicates with the expellant conduit upstream of the control valve and downstream of the flow control member so that the accumulator is normally pressurized by the expellant tank.

Abstract: An air conditioning system capable of regulating the temperature of incoming air and further comprising safety features relating to the sensing of abnormal conditions within a room or like treated area concerning the detection of fire, smoke or abnormally high temperature conditions.

Abstract: An improved clutch is described for use in a smoke and fire protection system comprising a pulley which in the normal operating position is engaged by a torque transmitting means so that the pulley may be controlled by an associated drive mechanism such as a stall motor or break motor. Either upon receipt of a signal from a remote source or upon an increase in the ambient temperature surrounding the apparatus, such as might occur during a fire, a heat responsive means disengages the pulley from the torque transmitting means thereby allowing the pulley to freely rotate about its axis to deploy its associated fire protection equipment. In the preferred embodiment, one or more bimetallic links of either "straight" or serpentine configurations are employed to move the pulley axially along its axis of rotation, thereby disengaging the pulley from an adjacent associated drive plate.

Abstract: A temperature-sensitive actuator is operatively connected to a valve by means of a spring-loaded linkage. The actuator causes a tensioned spring in the linkage to pass over center upon the occurrence of a predetermined temperature, thereby fully opening or closing the valve. The invention may be embodied in several forms including an automatic drain for water systems and a fire extinguishing system sprinkler control.

Abstract: A method and apparatus for removing fiber waste from yarn spinning rotors of open-end spinning machines and for removing trash waste liberated from fibers in their paths of travel to the respective rotors, utilizing a common primary airflow for drawing air from the rotors and for also drawing air adjacent the paths of travel of the fibers to the rotors so that the airflow adjacent such paths of travel will not interfere with movement of the fibers along such paths to the adjacent yarn spinning rotors. Preferably, the airflow from the rotors of each machine passes through a respective movable filter arranged to arrest fiber waste thereon periodically for intervals of predetermined duration permitting extinguishing of any fire which may have been ignited in the fiber waste being drawn from the rotors of the machines.

Abstract: An improved sprinkler for a fire protection sprinkler system in which the sprinkler opens to discharge water at one temperature and closes to stop the flow of water at a lower temperature. A pilot valve is actuated by a bimetal disc which also resiliently biases the pilot valve in a closed position. The bimetal disc has a snap action resulting in better control of the "on" and "off" temperatures of the sprinkler. A thermal delay for closing is obtained by the hysteresis which is designed into the bimetal disc.
