A sprinkler system comprises a network of CPVC conduits and a plurality of sprinklers. The system includes an electrically activated solenoid control valve to allow fluid to flow in the pipe network. One or more fire detectors operate independently of the condition of the sprinklers. Upon detection of an incipient fire situation, a fire detector sends an electrical signal to cause activation of the control valve. Upon activation of the control valve, fire suppression fluid is caused to flow through the conduits before the incipient fire situation matures into a sprinkler-triggering event. The cooling effect of fluid flowing through the conduit enables the conduit to resist structural failure prior to sprinkler deployment. The control valve may be disposed at a remote location in the sprinkler line and be operable as part of an inspector's test connection.

A sprinkler discharges a column of water downwardly onto a deflector that has a plurality of peripheral tines with a respective non-radial tapered notch separating each adjacent pair of tines. Opposed cutouts with tabs in the central portion of the deflector combine with the notches and with depressed peripheral tabs to produce a predetermined spray pattern.

The electrical appliances include a minimum complexity necessary to perform their primary functions and to communicate with the server. Additional complexity necessary for the electrical appliances to communicate with the cloud-based applications is enabled by the server remote from the electrical appliances.

A master control system for conserving water used by sprinkler systems within a predetermined geographical region includes a plurality of sprinkler systems each of which is assigned an identifying indicia. A transmitting station is arranged for transmitting control signals receivable at any location within the geographical region. A valve connects each sprinkler system to a water source for selectively feeding water to an associated sprinkler system when the valve is open and for precluding water from being fed to the associated sprinkler system when the valve is closed. A receiver is provided for each sprinkler system within the region connected to an associated valve for receiving the control signals and generating a disabling signal for causing only said valves for the sprinkler systems assigned said identifying indicia to open independently of their status. In this manner, said transmitting station can control and override the operation of selected sprinkler systems assigned said identifying indicia to regulate the extent to which water may be used within said geographical region in accordance with protocols established for the consumption of water by such sprinkler systems within said geographical region.

Methods and apparatus are disclosed for recovering metals from metal-containing support materials such as mineral ores. In one embodiment, the metal may be separated from crushed support material or ore in a bioleaching lagoon by the action of hydrocarbon-utilizing bacteria under anaerobic conditions. The bioleached material is then pumped into a precipitation lagoon where hydrocarbon-utilizing bacteria oxidize the metals under aerobic conditions. In another embodiment, metals may be directly biooxidized from a heap of the metal-containing support material having a hydrocarbon/oxygen injection system embedded therein. A water sprinkler system may be used to wet the heap while the hydrocarbon/oxygen injection system stimulates the growth of hydrocarbon-utilizing bacteria. The resulting effluent solution may be pumped or gravity fed to an aerobic precipitation lagoon where aerobic hydrocarbon-utilizing bacteria are used to precipitate or otherwise deposit the metals onto a deposition material.

Systems (100) and methods (800) for controlling a sprinkler system. The methods involve connecting a Sensor-Based Control System (SBCS) between a Sprinkler Control System (SCS) and at least one valve (106₁, 106₂, . . . , 106_N) and/or pump (109). A user-interactive session is performed to select a threshold value (THR) for a relative moisture content parameter. A Sensor Device (SD) measures a moisture content of soil contained in a tract of land (110). Thereafter, Measurement Data (MD) is communicated from SD (112₁, . . . , 112₅) to SBCS. MD includes information defining an amount of moisture content measured by SD. At SBCS, it is determined if the amount of moisture content exceeds THR. If the amount of moisture content does not exceed THR, an electrical connection is established between SCS and the valve. An electrical connection can additionally or alternatively be established between SCS and the pump.

A sprinkler system and a method for mitigating scaling, microbiological influenced corrosion and oxidative corrosion are disclosed. The system includes a piping network in fluid communication with a source of pressurized water and an air pump. The network is vented to the ambient. The air pump moves initially dry ambient air through the system, either by maintaining a negative or a positive air pressure within the network. The dry air absorbs residual water within the network and exhausts it to the ambient. Rate of air flow through the system is controlled by restrictor elements such as orifices, throttle valves or venturies within the piping network.
