A mounting and stabilization system including a base portion and a mounting portion pivotally coupled to the base portion. The base portion and the mounting portion have a closed configuration where the base portion and the mounting portion are generally parallel with each other and an open configuration where the base portion and the mounting portion are generally perpendicular with each other. The system further includes a collapsible container positioned between the base portion and the mounting portion, where the collapsible container is adapted to expand and receive ballast therein when the base portion and the mounting portion are in the open configuration. The collapsible container is adapted to collapse between the base portion and the mounting portion when the base portion and the mounting portion are in the closed configuration.

A temperature-control and fire-suppression system is provided for a system space, which optionally houses IT equipment. The system space has a ventilation system for providing controlled temperature air, for example to the IT equipment. A store of a fire-suppressing gas in liquid form is coupled to a supply means for supplying the fire-suppressing gas in liquid form to the system space, such that evaporation of the fire-suppressing gas in liquid form cools, or absorbs energy, from, the air in the system space. A temperature sensor is provided for sensing a temperature in the system space and a controller is responsive to the sensed temperature for controlling the supply means, to supply the fire-suppressing gas in liquid form while maintaining the sensed temperature above a predetermined lower temperature.

A fire suppression nozzle includes a first conduit including an inlet and an outlet, a second conduit coupled to the first and including a plurality of outlets spaced apart from a second plurality of outlets. The nozzle includes a first annular sound absorbing member positioned on a first side of the outlet and a second annular sound absorbing member positioned on a second side of the outlet wherein the first conduit provides inert gas to the second conduit. The inert gas exits the outlet in a first direction and a first portion of the inert gas is directed toward the first plurality of outlets in a second direction and a second portion is directed toward the second plurality of outlets in a third direction opposite the second direction, wherein the second and third directions are generally perpendicular to the first direction.

A fire-fighting appliance for distributing water droplets includes a rotating nozzle unit configured with nozzles distributed about the periphery of the nozzle unit, and a tubular element that is prepared for connection to a source of water for supply of water to the nozzles. Furthermore, the fire-fighting appliance includes a motor that is attached to the tubular element and is driven by the water pressure from the water source. The motor is rotatably connected to the nozzle unit and an adjusting device is provided for controlling the rotational speed of the motor for dispersing water droplets through the nozzles in a pulsating action.

Disclosed herein is a solid aerosol detonator capable of generating a fire extinguishing gas by vaporizing an internal solid fire extinguishing agent in order to extinguish a fire which may be generated in a place to live or an industrial place and a fire extinguishing apparatus using the same. The solid aerosol detonator and the fire extinguishing apparatus using the same can be detonated using only a fire extinguishing agent of a solid form without using an electronic match or an ignition agent, that is, a material coated on an electrical percussion. Accordingly, the combustion action of a solid aerosol can be stably generated because the solid aerosol detonator and the fire extinguishing apparatus using the same are not sensitive to a change in the physical properties and a change in the temperature even after a lapse of a specific time.

A storage facility includes a storage space, a container handling vehicle, a first upper vehicle support, a first lower vehicle support, a container delivery vehicle, a transit space, and a first separation wall. The storage space encloses a storage and retrieval system including a storage grid configured to store a plurality of storage containers in vertical stacks. The first upper vehicle support extends in an upper horizontal plane above the storage grid. The container handling vehicle is configured: to transport at least one of the plurality of storage containers by a wheel arrangement between at least two locations on the first upper vehicle support; and to vertically displace the at least one storage container by a lifting device. The first lower vehicle support extends in a lower horizontal plane below the first upper vehicle support. The container delivery vehicle operates within a lower section of the storage space above the first lower vehicle support. The container delivery vehicle is configured to receive the at least one storage container from the container handling vehicle and to transport the at least one storage container between at least two locations on the first lower vehicle support by a wheel arrangement. The transit space includes a second lower vehicle support extending in the lower horizontal plane and arranged relative to the first lower vehicle support such that the container delivery vehicle may move between the lower section of the storage space and a lower section of the transit space.
