A fire-fighting monitor for directing the flow of fluid from a fluid source includes a base, which is adapted to connect to a fluid source, and a monitor housing. The monitor housing includes an inlet and an outlet, with the inlet releasably mounted on the base and for receiving fluid through the base. The outlet is in fluid communication with the inlet for discharging fluid from the housing. A rotatable connection is provided between the inlet and the base. The inlet is rotatable about the base at the rotatable connection about a first axis. A drive mechanism is associated with the rotatable connection for rotating the inlet about the base at the rotatable connection. The monitor further includes a control system for selectively actuating the drive mechanism and includes a receiver for receiving an input signal from a transmitter remote from the monitor. The control system actuates the drive mechanism in response to the receiver receiving the input signal.

A flexible hurricane shutter or barrier to protect buildings from over pressure has inflatable cushions held in place by a fabric material capable of withstanding winds in excess of 100 mph. The barrier can be stored on site in a rolled fashion. Retainers are mounted on a building to guide and secure the longitudinal edges of the fabric to permit ease of deployment. The retainers may be spaced apart over one side of a building and the barrier may be deployed over an entire surface of a multi-story building by raising and lowering the fabric. Inflatable cushions are held between the fabric and the building. The inflated cushions reinforce the material and distribute the force of impact throughout the surface of the cushions and act as spacers to both hold the fabric off the structure and focus the forces onto stranger portions of the structure.

The invention pertains to a technology of manufacturing and assembling modular doors, which can be assembled on site, and specifically to modular doors, which can be assembled without a use of glue, by mortize and tenons.

The invention discloses an oxygen therapy device for agriculture, in particular to an automatic oxygen therapy crop waterlogging reduction device based on farmland water level. The automatic oxygen therapy crop waterlogging reduction device based on the farmland water level comprises an oxygen bottle, a water level monitoring device, a first automatic controlling valve and an underground pipeline device. The water level monitoring device is arranged underground, the first automatic controlling valve is arranged at the outlet end of the underground pipeline device, the water level monitoring device is connected with the automatic controlling valve, and the oxygen bottle is connected with the underground pipeline device. The water level sensing portion of the water level monitoring device is arranged near the upper portion of the underground critical depth of water, when a preset oxygen supplying condition is met, redundant water inside the pipeline is discharged, oxygen is transmitted to the root zones of crops automatically, the whole discharge pipeline is aerated, and the oxygen is dispersed to around root zones of the crops through holes on the discharge pipe. The automatic oxygen therapy crop waterlogging reduction device is capable of supplementing oxygen at the root zones of the crops to reduce the stress of waterlogging of crops, recovering vitality of the root zone of the crops, fully-automatic during the whole process of working, and beneficial for popularization.

The invention discloses a none-full-depth freezing method for penetrating through ultra-thick water-rich bed rock in shaft deepening. According to the method, a shaft penetrates through surface soil, the water-rich bed rock, a water-resisting layer and low-permeability bed rock sequentially from top to bottom, and main freezing pipes penetrate through the surface soil and the water-rich bed rock sequentially from top to bottom, penetrate into the water-resisting layer by 10m-20m and stop in a low-permeability rock stratum; a none-full-depth freezing depth is 240m-260m and a wall-caving-preventing freezing depth is 40m-45m; the main freezing pipes are annularly arranged with the circle center of the shaft as a circle center and the distance between the main freezing pipes and the outer wall of the shaft is 2m; wall-caving-preventing freezing pipes penetrate into the surface soil only by 43m and are annularly arranged with the circle center of the shaft as a circle center, and the distance between the wall-caving-preventing freezing pipes and the outer wall of the shaft is 1m. The method is fast in construction, safe and efficient and capable of preventing water damage caused when underground water damages a horsehead and related chamber rock mass along annular water diversion channels during construction of the horsehead after a full-depth freezing shaft is frozen, wherein the annular water diversion channels are formed by the freezing pipes and temperature measuring pipes; therefore, cost for treating water burst is saved, and safety construction of the horsehead and a chamber is guaranteed.

An overhaul line system includes a manifold that is attachable to, or formed integral with an attack nozzle. The manifold provides at least one quick connect coupling that allows an overhaul line to be connected to the manifold and to receive fire suppressing fluid from that manifold into a hose. The overhaul line has an elongated nozzle at its end remote from the quick connect coupling. A flow control valve is interposed between the elongated nozzle and the remote end of the overhaul line. A water treatment cartridge container can also be situated adjacent the flow control valve.
