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: Fire suppression apparatuses include a housing with gas generant material disposed therein, an initiator for igniting the gas generant material, and a cooling system. The cooling system includes a first chamber with a coolant material disposed therein and a second chamber. The coolant material is caused to flow from the first chamber into the second chamber to cool gas formed by the ignition of the gas generant material upon exiting from the housing under pressure. The cooling system may further include a piston disposed within the first chamber and movable responsive to gas pressure. Methods for cooling a fire suppressant gas and methods for suppressing a fire include flowing a fire suppressant gas into first and second chambers of a cooling system, flowing a coolant material from the first chamber into the second chamber, and contacting the fire suppressant gas with the coolant material to cool the fire suppressant gas.

Abstract: A fire suppression apparatus that includes a housing defining a first chamber containing a gas generant. The apparatus further includes an initiator operatively associated with the first chamber and in reaction initiating communication with the gas generant. The initiator, upon actuation, acts to ignite at least some of the gas generant to form gas. The housing further defines a second chamber adjacently disposed to the first chamber. The second chamber contains an endothermically-alterable material and a piston assembly including a piston. Upon actuation, the piston moves to expel at least a portion of the endothermically-alterable material from the second chamber such that the expelled endothermically-alterable material contacts and cools gas formed by the ignition of the gas generant. The housing further has at least one discharge opening to permit cooled gas to exit the housing. Corresponding or associated methods for suppressing a fire are also provided.

Abstract: A carbon dioxide cartridge is triggered when a lance with a piercing tip punctures its burst disc. The cartridge has a cap that has an outlet and a passage for the lance and puncturing tip to travel. The lance is pushed into the burst disc when a heat expanding substance which is stored hermetically the cap in such a way that the only direction to expand is to displace and push the lance right into the burst disc. Once the burst disc is pierced, the cartridge empties its contents quickly out the outlet. In at least one embodiment the cartridge and the cap are attached by screw threads.

Abstract: The present invention offers a solution to the potential hazards associated with an accidental overheating of a full compressed gas cartridge, by offering an automatic heat-actuable pressure discharge system. The compressed gas cartridge is protected from dangerous explosions caused by excessive heat by the use of a lance that pierces the compressed gas cartridge safely when a spring loaded hammer is released from its constraints when a length of heat sensitive material fails in the presence of excessive heat, thereby avoiding a very serious fire hazard.

Abstract: Improvements to a portable fire extinguisher where the improvements relate to a system where the owner of the extinguisher can service and maintain their fire protection. Systems in place today require the servicing of a third party. The service companies (third parties) are charged with maintaining the system. Further Improvements include an anti-bridging mechanism that is articulated from the exterior of the chamber to fluff, mix or stir the powder within the chamber to keep it in a liquefied state. The improvements further include a wall mounting bracket that reduces tampering with the extinguisher, an automatic fluffing motor and manual fluffing wheel with a chuck for use with a drill. These features extend the service intervals while maintaining the fire extinguisher in a ready condition. The fire extinguisher is construction of components that are interchangeable and provide equal operation for left and right handed people.

Abstract: The present invention comprises an extension tube that attaches to the bore end of a water jet producing device that is used to render safe improvised explosive devices by disrupting the firing train of said devices. The present invention comprises an extension tube having a sudden enlargement of cross section, that may be formed by adjusting the dimensions of the interior diameter of the extension tube, at the point of attachment, and a series of apertures in the attachment tube. The extension tube provides a more uniform jet of water with more focused energy by containing the jet until breech pressures are vented. Better control of the water jet will be maintained during firing operations. Further, more energy may be put into the water jet to accomplish specific tasks.

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: In fire-fighting equipment having a drive unit for supplying extinguishing liquid, the drive unit is at least one hydraulic accumulator in which a high initial drive pressure falls to a reduced drive pressure in use. The hydraulic accumulator supplies only the extinguishing liquid at the high initial drive pressure and a mixture of the extinguishing liquid and a gas at the reduced drive pressure. For this, the hydraulic accumulator has a liquid space for the extinguishing liquid and a gas space for the gas that each communicate through an outlet valve with an outlet line for the use. The outlet valve responds to the high initial drive pressure and reduced drive pressure for opening only a liquid outlet connection at the high initial drive pressure and opening also a gas outlet connection at the reduced drive pressure.
