This invention relates to any field where crafts (such as avionics) where inhabitants of volumes like passage compartments can be found where the area is subject to extreme conditions such as explosion, fire or other traumatic activity linked with a crash, and more specifically a process and method for the protection of inhabitants or passengers in the volume in the craft using a system for the protection of the inhabitants or passengers in the volume using both an anti-trauma apparatus for blast release of a first chemical within the volume for shock protection and for an anti-explosion apparatus for the blast-release of a neutralizing chemical compound within the fuel tank reservoir in a craft to neutralize the inflammability and explosion capacity of the fuel in the tank to avoid detonations and damage to an adjacent volume.

A method of fire suppression may include injecting a reactive agent into a reaction zone to produce a catalytically active species for fire suppression and conveying the catalytically active species to a fire to catalytically interfere with flame chemistry of the fire. Fire in a fuel tank may be suppressed by injecting the reactive agent into a convective flow of a mixture of fuel and oxidizer in a fuel tank, the reactive agent reacting in the fuel tank to release a species which catalytically interferes with flame chemistry to suppress fire in the fuel tank. Fire at an airplane crash may be suppressed by releasing the reactive agent from the container at the crash site to produce an active species to catalytically interfere with a fire at the crash site.

A fuel tank inerting system includes a primary catalytic reactor comprising an inlet, an outlet, a reactive flow path between the inlet and the outlet, and a catalyst on the reactive flow path. The catalytic reactor is arranged to receive fuel from the fuel tank and air from an air source that are mixed to form a combined flow, and to react the combined flow along the reactive flow path to generate an inert gas. The system also includes an input sensor that measures a property of the combined flow before it enters the primary catalytic reactor and an output sensor that measures the property of the combined flow after it exits the primary catalytic reactor.

A fuel tank inerting system is disclosed, comprising a fuel tank and an electrochemical cell comprising a cathode and an anode separated by a separator comprising an anion transfer medium. A cathode fluid flow path is in operative fluid communication with a catalyst at the cathode between a cathode fluid flow path inlet and a cathode fluid flow path outlet. An anode fluid flow path is in operative fluid communication with a catalyst at the anode, and includes an anode fluid flow path outlet. An electrical connected to a power source is arranged to provide a voltage difference between the anode and the cathode. An air source is in operative fluid communication with either or both of the cathode flow path inlet and the anode flow path inlet. An inert gas flow path is in operative fluid communication with the cathode flow path outlet and the fuel tank.

A flame mitigation device (FMD) for use within a portable fuel container includes a generally cylindrical body having an interior sidewall and exterior sidewall. An annular rim is configured at an upper end of the body and a bottom wall is further configured at a lower end of the body. The FMD includes one or more indented fuel flow members extending from the interior of the annual rim for decreasing cyclonic effect of fuel flowing into the body and a plurality of stepped ribs configured on the interior sidewall of the body for centering diesel and gasoline fuel pump nozzles when inserted into the body. A reverse domed shaped bottom help to disperse fuel though a plurality of substantially rectangular shaped holes through the side wall and bottom wall.

A temperature controller for a heater for a container for use in hazardous areas and a method of programming such a temperature controller. The method of programming such a temperature controller comprises the steps of writing identification data and parameter data to a memory of a portable token in an area remote from the hazardous area; transporting the token to a position in proximity to the temperature controller in the hazardous area; transmitting, by means of near field communication, the identification data and parameter data stored in the memory of the portable token to a receiver in the temperature controller; comparing the identification data received by the temperature controller with identification data stored in a memory of the temperature controller; and if said comparison of identification data is positive, and updating parameter data stored in the memory of the temperature controller with the parameter data received by the receiver.

A catalytic oxidation system for generating inert gas includes a catalytic oxidation unit, which includes a catalyst oriented between an inlet and an outlet of the catalytic oxidation system, a first temperature sensor in operable communication with the catalyst, and a second temperature sensor in operable communication with the catalyst. The first temperature sensor is nearer to the inlet than the second temperature sensor and the second temperature sensor is nearer to the outlet than the first temperature sensor.

A fuel tank inerting system includes an air separation module with an oxygen permeable membrane and a variable vacuum source in fluid communication with the air separation module. The variable vacuum source provides an adjustable vacuum to the permeate side of the oxygen permeable membrane in the air separation module, driving production of inert gas for fuel tank inerting or fire suppression.

A safety cabinet for storing flammable liquids is provided with a flame arresting vent. The flame arresting vent or flame arrestor allows flammable vapors inside the cabinet to leave the cabinet's interior but prevents flame from flowing into the cabinet's interior from outside the cabinet.

The present invention includes systems, assemblies, and methodologies for inhibiting combustion within fluid containers, enhancing the safety of such containers. One aspect includes a novel apparatus for assembling a base module of the present invention. The apparatus may include an initial stage, and intermediate stage, and a rolling stage. The initial stage is operative to receive a spool of mesh material. The intermediate stage is operative to conduct the mesh material between the initial stage and the rolling stage, as well as carry out a number of other operations associated with the present invention. The rolling stage is operative to roll the unspooled mesh material into a base module in accordance with at last one embodiment of the present invention.
