Device (1) for closed systems for equalization of pressure surges, having an outlet nozzle (2), on which an impact plate (3) is provided and a hinged cover (4) is mounted pivotably, wherein the hinged cover (4) lies in a rest position (5) on the outlet nozzle (2) and in an open position (6) bears on the impact plate (3), wherein at least one holding-closed device (7) is provided, which presses the hinged cover (4) in the rest position (5) against the outlet nozzle (2) and in the case of a pressure surge releases the hinged cover (4), wherein the device has a control unit (8) that controls the holding-closed device (7).

A subsea fluid storage system comprising a soft bladder disposed within a pressure balanced reservoir, a rotatable piston, and a piston rotator which rotates and twists the rotatable piston as it travels along a predetermined axis within the pressure balanced reservoir, predictably and repeatabley collapses the soft bladder when the rotating piston cooperatively travels about the piston rotator, twisting the soft bladder as the rotating piston moves along the predetermined axis, collapsing the bladder inward and thereby emptying the bladder of fluid within the bladder. The piston's rotation pulls the soft bladder away from the pressure balanced reservoir's interior, thereby preventing the bladder's binding or pinching the pressure balanced reservoir's interior. In configurations, fluid is allowed to enter the pressure balanced reservoir via a valve until a balance is achieved between an interior and an exterior of the pressure balanced reservoir.

Embodiments described herein include layered mesh containers and methods for using the containers to safely transport and dispose of airbag inflators having ammonium-nitrate-based propellant. For example, a container is provided that can hold multiple airbag inflators and withstand up to 4 moles of matter being deployed from an inflator having ammonium-nitrate-based propellant. The container can contain the inflator and any shrapnel associated with the explosion while also venting gases expelled as a result of the explosion. Various container designs are provided, along with methods for using these containers.

A container may have a floor, a ceiling, a first side wall, and a second side wall, a first end wall, and a second end wall. The first side wall, the second side wall, the first end wall, and the second end wall may be formed from a container wall for reducing an effective radar cross section of the container. The first side wall and the second side wall in a longitudinal direction of the container mid-height between the floor and the ceiling may be foldable inward into the interior of the container. The first side wall may include a first cladding board that is permeable to radar rays and reduces the effective radar cross section of the container. The first cladding board may have a reflective agent that reflects radar rays and can be aligned to be at least partially inclined relative to a plane of a main extent of the first cladding board.

A leak preventing appliance and method for preventing liquid from leaking out of a damaged tank (2). The appliance comprises a suction head (4) to be pressed against an outer wall (5) of the tank under the effect of an underpressure generated by a vacuum pump (3). The suction head comprises a first chamber (6) and a second chamber (9) arranged around the first chamber. Each chamber has an opening (7, 10) intended to face said tank wall. The suction head is attachable to the tank wall under the effect of a reduced pressure produced in the second chamber by the vacuum pump. The first chamber is connectable to the vacuum pump via a valve device (8), which is configured to keep the first chamber connected to the vacuum pump when a reduced pressure produced in the second chamber by the vacuum pump is below a threshold value and to otherwise keep the first chamber disconnected from the vacuum pump.

The disclosure relates to a flameless venting system, along with associated devices and methods. In one aspect, the disclosure is directed to a flameless venting system having a curved flange, which may allow the system to mount directly to the curved surface of a vessel. In another aspect, a disclosed flameless venting system has a curved filter exit. In still another aspect, a disclosed flameless venting system may be configured such that a flame-arresting quenching body component may be joined to a vessel prior to installation of an explosion panel component. In addition, a quenching body component may be configured to provide access to its interior, to facilitate inspection, replacement, or maintenance of an explosion panel contained therein.
