Abstract: An odor generation alarm and a method for informing an unusual situation having a high attention attracting effect and a high degree of safety are provided. An odor generation alarm includes an odorant receptacle, a drive section, a detector and a circuit section which is a controller. The odorant receptacle contains an odorant. A concentration of the odorant in air at which a person can no longer tolerate a strength of smell is lower than a no observed effect concentration of the odorant. The drive section causes the odorant to be emitted from the odorant receptacle. The detector detects occurrence of an unusual situation, and outputs a detection signal. When the detection signal from the detector is inputted, the controller causes the drive section to emit the odorant in accordance with the detection signal.

Abstract: A protective device with a pressure tank (1) includes an elastic extinguishing agent balloon (3) filled with an extinguishing agent (23) and a propellant, where the elastic extinguishing agent balloon (3) borders onto at least one elastic component (32) and this elastic component is fluid permeable. The upper part of the elastic extinguishing agent balloon (3) is formed as a sealing ring. The device has the advantage that when it is used in mobile and stationary objects, where vibrations and other forces act on the extinguishing device, a high degree of operational safety of the extinguishing device can be assumed, that makes it possible to discharge almost 100 percent of the extinguishing agent without any malfunctioning. The operation of the extinguishing device is also temperature independent so that no additional safety measures are required in the case of a change in the spatial attitude of the pressure tank.

Abstract: A device for discharging a fire retardant material comprising a housing capable of storing a fire retardant material. The housing has an initiator attached to a first end, while a discharging port is attached at a second end. Additionally, sealed within the housing is a driver which forces the fire retardant material towards the discharging port.

The choke assembly has a choke body with a first and second cavity. Furthermore, choke body has passageways and apertures for directing the flow of both the fire retardant material and the pressurized gases.

Abstract: A device for protecting flammable fluid reservoirs, or the regions in immediate proximity thereof, from the hazards due to impact and reservoir rupture, and subsequent potential of fire, corrosion or other damage or injury due to contact with reactive fluids. Such impacts may arise from collisions, such as encountered in transportation systems, or structural or thermal failure and/or rupture of components and systems, or separation of system components. Such a device may be formed as a close-fitting shroud over such components, or surrounding fittings and junctions of mating components in such systems, or mounted near the location of such components in the direction of impact or failure. Such a device may have a pattern of pre-scored lines to facilitate break-up of the device upon impact or thermal stress.

Abstract: A method and apparatus for dispensing a liquid, such as a fire suppressing gent, with a gas wherein both the liquid and a combustible propellant for generating the gas are stored in separate sealed compartments at atmospheric pressure. The liquid is stored in a chamber between an annular piston and a central pedestal containing a gas generating canister. A portion of the gas generated drives the piston to expel the liquid into a mixing chamber in the pedestal, and another gas portion is fed into the mixing chamber so as to mix with and propel the liquid through a nozzle. The liquid may be atomized or vaporized depending on its composition. Mixing of the liquid with the gas may be enhanced by tangentially injecting the liquid into the mixing chamber.

Abstract: A nozzle unit for discharging and atomizing a fire or explosion suppressant comprises a rigid-walled cylindrical container having a nozzle portion at one end with radially directed discharge orifices. A rupturable barrier normally blocks the nozzle portion from the interior of the container. At the other end of the container, a piston is positioned so as to be sealingly slidable along the container in response to pressure generated by a gas pressure generator. The moving piston pressurizes the suppressant agent within the hollow interior until the rupturable barrier bursts. The suppresessant agent is accelerated substantially instantaneously and discharged in atomised form through the discharge orifices. The gas pressure generator may be a pyrotechnic gas generator. The arrangement is such that the pressurizing gas does not come into contact with the suppressant agent.

Abstract: A pressurized container consisting mainly of a protective flask, a lid, an elastic storage bag disposed within the flask, and a working bag disposed within the elastic storage bag. The elastic storage bag is filled with a predetermined amount of a desired medium to be dispensed. Then, the working bag is filled with air or another appropriate working fluid. The pressure exerted from the working bag on the elastic storage bag causes the elastic storage bag to expand until lining the interior of the protective flask. A deaerating vent is provided on the protective flask to allow air trapped between the elastic bag and the protective flask to escape. The added pressure supplied by the working bag assures that all of the contained medium will be dispensed. The protective flask also may include an opening and a puncturing tip covered by a thermal fuse. When the thermal fuse melts, the puncturing tip ruptures the elastic storage bag, thereby dispensing the medium contained inside.

Abstract: An automatically activated fire extinguishing apparatus mounted within a stove hood. The apparatus has a plastic bag liner enclosing a composition of fire extinguishing materials under pressure within a metal necked container. A pressure gauge housing having an interior channel containing an end of the plastic liner separates the necked container from an actuating header. A plastic nipple, located in a channel of the actuating header, closes an open end of an insert connected to the plastic liner. A fire sensitive device actuates a trigger which causes a cutting ram to sever the end of the nipple to permit exit of the fire extinguishing composition.

Abstract: Disclosed is a fire extinguisher comprising a container separated into two compartments, one compartment containing pressurized gas and the other containing an extinguishant. The container has a valve to release the extinguishant, which is forced from the container when the bladder is expanded by the pressurized gas. The center of the bladder has a force absorbtion means for protection against the impact of the bladder striking the inner wall of the container. The force absorbtion means has two disks clamped together to retain an annular bead of the bladder.

Abstract: This invention relates to novel composition and methods for neutralization and solidification of hazardous acidic spills. A dry particulate composition of varying reaction grades of alkaline compounds and varying grades of absorptive materials may be used to neutralize and solidify acidic spills, solidify the spills and render them harmless. These compositions may be applied to the spills by fire-extinguisher-like delivery devices which spread the compositions on the spills from a relatively safe distance without splattering the hazardous material.

Abstract: An explosion suppression system wherein a photodetector (10), a capacitor circuit (12) and a detonator (14) provide an initiation signal to a dispersion tube (18). The dispersion tube includes a casing (20) having orifices (26), an inner tube (28) where the explosion suppressant is stored, and a propellant cord (34) that is located between the storage casing and the inner tube. In response to the initiation signal, the explosion suppressant is expelled from the orifices (26) and through nozzles (27) to form a controlled spray pattern to quench initial flame in a fuel tank before there is time for a damaging pressure rise.
