Firefighting gas releasing apparatuses may include a trigger housing. A containment shell may have a plurality of shell sections pivotally carried by the trigger housing. The plurality of shell sections may be positional in a closed shell configuration and an open shell configuration. A shell interior may be formed by the containment shell in the closed shell configuration. The shell interior may be configured to contain a supply of at least one fire-suppressing gas. A selectively-actuatable shell releasing assembly may be carried by the trigger housing. The shell releasing assembly may be configured to engage the plurality of shell sections and maintain the containment shell in the closed shell configuration and disengage the plurality of shell sections for deployment of the containment shell to the open shell configuration. Firefighting gas releasing methods are also disclosed.

The invention relates to an inertization apparatus for inerting a working volume in a chemical production plant by flushing with inert gas, where the chemical production plant comprises a plant-wide inert gas distribution system having pipes for distributing the inert gas and at least one inert gas offtake position which can be connected to a connecting conduit. According to the invention, it is provided that the connecting conduit between inertization apparatus and working volume is connected, at its end nearest the working volume, in a not reversibly detachable manner to an intermediate piece, where the intermediate piece can be connected in a reversibly detachable manner to a counterpiece provided on the working volume.

Fire protection and suppression apparatus, materials, systems, and methods of use thereof are disclosed. In fire extinguishing applications, aerosol extinguishing agent in sheets, panels or other forms can be placed in a variety of implementations, including one or more of, but not limited to, inside an enclosure that contains a fire hazard, in an interior of a fire hazard itself, incorporated into a structure of a fire hazard. Once initiated, the aerosol extinguishing material will burn to create and directly disperse the aerosol particulate that can extinguish the fire. Initiation of the aerosol agent can be by flames or heat from an unwanted fire. Alternative methods of initiation include electric initiators that are signaled by automatic fire detection systems, electric manual methods, or mechanical/thermal initiators.

A fuel tank inerting module, a fuel tank inerting system for an aircraft, and a method of providing fuel tank inerting systems for aircraft are disclosed. The module includes an inlet for ullage gas from a fuel tank, a catalyst, an outlet for the ODA, sensors, filters and valves. The module is sized and shaped to fit in a range of positions near to fuel tanks in various aircraft. The inerting system includes one or more modules connected to the fuel tanks and a controller to control passage of ullage and ODA between the fuel tanks and the modules. The method includes providing an inert gas generation module compatible with any suitable aircraft, positioning one or more modules in an aircraft at locations near to a fuel tank to be inerted.

An ergonomic seam ripper includes: (a) an elongated haft with a bulged profile having a larger cross-section about its medial portion than cross-section at a palm end of the haft, the cross-section about the medial portion of the haft also being larger than a cross-section at a thumb grip end of the haft, wherein the palm end of the haft has an outer surface of generally planar structure and the haft is further characterized by a mounting portion at the thumb grip end of the haft; (b) a gripping member secured to the mounting portion of the haft made of a resilient rubbery material with a plurality of gripping ribs extending thereabout, wherein the gripping ribs are spread relatively close together at an upper portion thereof and relatively further apart at a lower portion thereof; and (c) a U-shaped cutting blade with a tapered projection and balled projection, as well as a shaft, wherein the shaft of the blade is secured to the haft such that the tapered projection is aligned with the upper portion of the gripping member and the balled projection is aligned with the lower portion of the gripping member.

A fire extinguishing device comprising liquid nitrogen filled canister-tank attached to a device to release the LN contents; wherein, the release mechanism comprises a small explosive to tear open the canister and rapidly disperse the LN. The bombs are opened at desired locations and are delivered by any means comprising the aerial, vehicle, drone, robotic systems and hand operated by firemen. The device is used for the purpose of extinguishing forest fires or structure fires.

An exemplary robotic parking device of the present disclosure includes a number of stacks of containers. The stacks being positioned within a frame structure including uprights and a horizontal grid disposed above the stacks. The grid having substantially perpendicular rails on which load handling devices can run. Cars or vehicles are positioned in containers and are moved into and out of the stacks by the robotic handling devices running on the grid. The cars are put into the grid at entry points that may be positioned at points under the stacks.

A vehicle for use with an object handling system, the object handling system including two substantially perpendicular sets of rails forming a first grid, a plurality of first uprights supporting the first grid, a plurality of containers arranged in stacks, each stack being located underneath the first grid, one or more robotic load handling devices configured to drive on top of the rails of the first grid, the one or more load handling devices including means for removing or replacing at least one container from the stacks. The vehicle includes two substantially perpendicular sets of rails forming a second grid substantially at the top of the vehicle above a storage space for carrying containers. The second grid interfaces with the first grid to allow the one or more load handling devices to drive from the rails of the first grid onto the rails of the second grid.

An electrical device having a housing containing at least one electrical component and an automatic fire prevention or extinguishing system with at least one heat and/or smoke sensor, the at least one heat and/or smoke sensor is operably connected to a container holding a fire-retarding, fire-extinguishing or fire-prevention material and the container is arranged to dispense the fire-retarding, fire-extinguishing or fire-prevention material into the housing and/or onto the electrical component when the at least one heat and/or smoke sensor detects heat and/or smoke inside the housing, as the fire-retarding, fire-extinguishing or fire-prevention material is dispensed through at least one conduit operably connected to the container holding the fire-retarding, fire-extinguishing or fire-prevention material. Each conduit is arranged to track electrical wiring of the electrical device or track at least part of an outer surface of at least one electrical component of the device.
