The chain has a length sufficient to be positioned about the water line and received by the eyehooks so that plate is securely positioned along the elongated cylinder below the discharge valve nut. | 02-19-2015 |
20150083441 | Electrically Operated Gas Vents For Fire Protection Sprinkler Systems And Related Methods - A fire protection sprinkler system includes a water source, a sprinkler, a piping network interconnecting the water source and the sprinkler, and an automatic gas vent coupled to the piping network and configured to discharge gas from the system. The automatic gas vent includes a sensor configured to sense a presence or absence of a liquid and an electrically operated valve. The automatic gas vent is configured to open the electrically operated valve in response to the sensor sensing the absence of a liquid and close the electrically operated valve in response to the sensor sensing the presence of a liquid. Automatic gas vent assemblies and methods of venting and discharging gas from fire protection sprinkler systems are also disclosed. | 03-26-2015 |
20150129244 | SYSTEM AND METHODS FOR DELIVERY OF MATERIALS - A system and methods for delivering materials including a device with a central manifold portion comprising an intake and one or more outlets through which the quantity of and the pressure and direction at which material is delivered may be controlled. Devices according to the invention control delivery of materials by achieving one or more properties such as flight elevation, flight stabilization, flight maneuvering, environmental resiliency, and ejection of material such as water. | 05-14-2015 |
20150136428 | MIST TYPE FIRE PROTECTION DEVICES, SYSTEMS AND METHODS - Various mist-type fire protection systems for the protection of light and ordinary hazard occupancies of reduced water demand as compared to known mist type systems or sprinkler systems configured to protect the same occupancies. Three system configurations are defined by varying design criteria for the installation of: mist devices having an enlarged coverage area alone or in combination with known nozzles or sprinklers. The preferred mist devices provide for the protection of at least one of a light hazard occupancy only and a light and ordinary hazard occupancy having a ceiling with a maximum ceiling height of at least 8 ft. The preferred device include a body having a passageway defining a K-factor of less than 1 gpm/psi | 05-21-2015 |

20150367156 | SPRINKLER COMPRISING A SHUTOFF MEMBER HELD IN POSITION BY A FUSIBLE MEMBER WITH THE AID OF A MOVEABLE BEARING MEANS - A sprinkler is provided for a firefighting installation including a network of vacuum sprinklers. The sprinkler includes: a fixing connector, which allows the sprinkler to be connected to pipe work and has a nozzle; a fusible member; and a shutoff member for shutting off the nozzle, held in shutoff position by the fusible member. The fusible member is kept bearing against the shutoff member by a moveable bearing, capable of allowing the shutoff member to leave its shutting-off position when the pressure in the nozzle exceeds a predetermined pressure. An ejecting element for ejecting the shutoff member is mounted outside the nozzle and acts in a pulling sense on the shutoff member. | 12-24-2015 |

20160051850 | Fire Protection System - A wild fire protection system is provided. The system is positioned about a building or buildings to be protected, and has a number of fire suppression distributors such as water spraying devices. A plurality of fire sensors are in computerized communication with the distributors and activate them once a fire is sensed. The system is configured to hold back an oncoming wildfire far enough from the building to prevent its damage, and to prevent the spread of the wildfire near the building. | 02-25-2016 |
20160121149 | TUNNEL FIRE PROTECTION SYSTEM - A deluge fire protection system for tunnels having vehicle traffic including a main water supply pipe and a horizontal spray nozzle arrangement. The horizontal spray nozzle arrangement includes a nozzle device having an inlet portion defining an internal diameter and an external nominal diameter. The horizontal spray arrangement includes a coupling arrangement between the main water supply and the nozzle device. The coupling arrangement defines a multi-direction flow path between the main water supply and the nozzle device. The multi-direction flow path has an effective length of at least eight times a diameter of the inlet portion, and a cross-sectional area along the effective length greater than the cross-sectional area defined by a diameter of the inlet portion of the body of the nozzle device. The coupling arrangement provides for water delivery to the nozzle device at a working pressure ranging from about 10 psi. to about 30 psi. | 05-05-2016 |
20160375287 | FIRE-SPRINKLER PROTECTION SYSTEM AND METHOD FOR A COMBUSTIBLE CONCEALED SPACE - A fire-sprinkler protection system for a combustible concealed space having a sloped ceiling has a plurality of fire-sprinklers including pendent sprinklers and sidewall sprinklers disposed beneath the sloped ceiling. Each pendent sprinkler provides a spray pattern that is generally circular cylindrical about the sprinkler. Each sidewall sprinkler provides a spray pattern that is generally rectangular in shape. The hydraulic demand for each sprinkler is substantially equivalent to the projection hydraulic demand for the horizontal footprint projection of the sloped ceiling on the floor. A piping system is coupled to each sprinkler by a plurality of branch lines is sized to provide the hydraulic demand for each sprinkler. | 12-29-2016 |
