Abstract: A self-recocking actuation device. One possible use for it is in conjunction with a pneumatic fire protection system. This invention employs the process known as occlusion to store large amounts of gas in a small volume. Metal hydrides in a chamber are used to store hydrogen in the disclosed preferred embodiment. Upon the application of heat--from a heat source like a resistance heater--the charged metal hydride releases its hydrogen (H.sub.2) in a chamber having only one exit opening which empties into a sealed bellows. This bellows contacts a piston located in another chamber wherein a biased resetting spring is provided to normally maintain the piston in contact with the bellows. As the pressure from the H.sub.2 gas builds up, it overcomes the biased spring to move it and the piston along with an associated pin or other actuator.

Abstract: The method and appliance for fire extinguishing according to the present invention are suitable for use in stationary depot premises, baggage and engineering compartments of transportation facilities, etc. According to the method of the invention, at a suitable position in a compartment, an individual container is fixed, which is fitted with a fuse 3 responding to infrared radiation and carries a fire extinguishing compound whose function is effectuated by a chemically active liquid inhibitor confined in miniature capsules made from thermoplastic material and which is distributed over the compartment after ignition of the fuse 3 by conversion from a liquid to a gas. Vapors of the gaseous inhibitor escape from the container and produce a noncombustible atmosphere in the compartment. The appliance for performing this method embodies a container made non-gastight and fitted with a thermal charge placed inside it in the form of a rod manufactured from a highly inflammable oxygen-containing substance.

Abstract: A fire protection means comprises a panel consisting of a honeycomb core, having in cells thereof a fire-extinguishing fluid, and of facing sheets bonded to each face of the core, the panel being arranged so that, in use, it is more rigidly enclosed on one side than the other. On entry of, or impact with, a projectile, the facing sheet on the less rigidly enclosed side of the panel peels away, or otherwise preferentially breaks up or away, consequent upon passage of the projectile and/or the ensuing hydraulic shock, so that the fire-extinguishing fluid is rapidly liberated from a large proportion of the area of the panel and substantially in the preferred direction to suppress or extinguish rapidly any fire caused by entry of the projectile.

Abstract: A fire extinguisher of the type comprising a burstable container adapted to provide a high mass flow rate of discharged extinguishant is provided with venting means so adapted to direct the flow of extinguishant from the container that the reaction forces upon the container during discharge of extinguishant compensate one another to reduce the resultant force upon the container.

Abstract: Disclosed is an automatic fire-extinguishing system comprising one or more portable automatic fire-extinguishers placed at desired locations within a region wherein automatic extinguishment should be effected when a fire occurs therein. Each of the fire-extinguishers includes integrally a bomb containing a fire-extinguishing gas under a pressure condition and a gas jetting nozzle connected through a valve to the bomb. At least one fire sensor is arranged at a desired location within the region. Each fire extinguisher is provided with an electro-mechanical means for opening the valve, an electrical means for actuating the opening means and an internal gas pressure detecting switch, and; an electric control circuit formed by the combination of the electric circuit of the opening means, electrical actuating means and the gas pressure detecting switch which are connected in series.

Abstract: A fire-extinguishant mechanism comprising a thick-walled bottle containing pressurized fire extinguishant liquid. Liquid outflow from the bottle is through a poppet valve located at the lower end of the bottle; the valve discharges pressurized extinguishant in one or more preselected directions, depending on the location or application of the bottle system; valve actuation is by means of an explosive squib and/or explosive cartridge (as backup). The bottle is initially filled and pressurized through a multi-purpose fitting at the bottle upper end; a filler tube extends from the fitting downwardly into the bottle to introduce the pressurizing agent below the liquid extinguishant surface. The fitting is specially constructed to mount a charging valve, a pressure gage, rupture disc, and liquid deflection mechanism.

Abstract: The invention consists of a Christmas tree ornament which contains a fire extinguishing powder. When the ornament is exposed to an elevated temperature such as a flame heat sensitive adhesive holding the ornament together softens and a spring within the ornament forces it apart releasing the powder thus extinguishing the flame.

Abstract: Panels and other objects are formed by blowing hollow bubbles of plastic into a mold and stacking the bubbles in the mold in abutment with each other while the bubbles are tacky to form a mass of bubbles bonded together in a desired contour. The bubbles are formed by blowing successive bursts of compressed air into a mass of plastic material confronting an orifice and cutting the bubble off from the mass of plastic material on the side of the orifice opposite the liquid plastic. A panel for construction purposes is illustrated and includes fire extinguishing means integral with the panel.

Abstract: A heat actuated valve comprises a base adapted to be mounted on a fire extinguisher container. The base includes a passsage communicable with the container interior. A pair of stop fingers extend forwardly from the base. A fusible element interconnects the stop fingers. The base, stop fingers and fusible element are of one-piece, integral construction. A plunger is slidably mounted in the passage and includes a passage-blocking portion which blocks the passage when the plunger abuts the stop fingers during a fire sensing mode of operation. The plunger is slidable rearwardly to shift the passage-blocking portion to a first passage-opening position to allow the container to be filled. The plunger is operable, in response to melting of the fuse, to spread the stop fingers apart and travel forwardly sufficiently to shift the passage-blocking portion to a second passage-opening position, enabling the container contents to be discharged.

Abstract: A pressure sensitive exposion barrier which is activated by a static pressure rise. A liquid tight housing with a latched door contains the explosive suppression agent, usually water, until activation takes place. Upper hinges on the door allow it to be pivoted outwardly and its agent released. Normally a latch keeps the door locked until the pressure rise from the explosion causes a connected bellows assembly to be depressed. Once depressed, the latch is released and the door is forced outwardly by a biasing member to release the agent before the explosion arrives.
