Abstract: A monitoring and testing system which is designed to automatically seal off the system from its gas supply and monitor internal pressure during that time to perform regulatory testing. The scheduling can be automated and can be done without maintenance personnel having to monitor the time passage and pressure manually. The system may also be designed to monitor operation of the air compressor, or related gas supply device, and evaluate if the operation of the gas supply is operating in a fashion indicative of a larger than desired leak. This effectively allows the system to monitor pressure changes during regular operation and on a somewhat continuous basis.

Abstract: A fire sprinkler head has a valve with an X-brace latch, and includes a flexible conduit. A sprinkler nozzle is secured to a first end of the flexible conduit. The sprinkler nozzle includes a first fitting, a sprinkler orifice and fusible element. A second fitting is secured to the second end of the flexible conduit and includes the valve. The valve has a valve element which is moveable from a latched position to an unlatched position. A flexible link extends from the sprinkler nozzle to the X-brace valve latch. Breaking of the fusible element releases the flexible link to move from the latched position to the unlatched position, releasing the valve for flow there-through.

Abstract: A storage system is described where goods are stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of tracks on which load handling devices run. The load handling devices take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked out. The framework may be provided with one or more of the following services: power, power control, heating, lighting, cooling, sensing, and data logging. A method of partitioning the storage system prevents the spread of fire or prevent damage caused by sprinkler activation.

Abstract: Provided is a fire extinguisher which reduces a risk of a discharge accident caused when a stopper is unintentionally separated at a normal time and from which a handle is easily pulled out when fire occurs. According to the fire extinguisher, a force pressing an upper handle is not transmitted to a valve stem as a gap between the upper handle and a plug is maintained by a gap support part when the stopper is installed on the handle, and the force pressing an upper handle is transmitted to the valve stem through a valve pressing part as the gap support part horizontally moves by an elastic member so as not to overlap the plug when the stopper is separated from the handle.

Abstract: A protective device includes a pipe in a pipe system for transmission of a flow of a fluid from an upstream end of the pipe system to a downstream end of the pipe system. The device includes a pipe insert, disposed within the pipe system between the upstream and downstream ends. The pipe insert has a cylindrical body. A valve is within the pipe insert and is moveable between open and closed positions. The open position opens the pipe insert, enabling transmission of the flow of the fluid, and the closed position occludes the pipe insert, disabling transmission of the flow of the fluid. A sensor is within the pipe insert for disposition within the flow of the fluid to detect a target compound in the pipe insert. The valve moves from the open position to the closed position when the sensor detects the target compound.
