20080283255 | Liquid Nitrogen Enabler Apparatus - A Liquid Nitrogen Enabler Apparatus is disclosed herein, wherein the apparatus may be configured to protect the earth, people and property. The apparatus is configured to distribute liquid nitrogen that converts to nitrogen gas to achieve its desired effects. Nitrogen gas carries the temperature, the inertness, and the tendency to cloud, gather amongst itself with the exclusion of other gases. Combining the thermal qualities with the inertness of the nitrogen gas, fires and other such crises are handled. There are various advantages associated with treating fires and other such crises with liquid nitrogen such as that when the liquid nitrogen converts into a gaseous form and is applied to a fire draft, rather than directly to the fire itself. The fire draft will pull the gaseous nitrogen into the fire, thus ending the burn. | 11-20-2008 |
20090211771 | Regulated Valve Assembly for Fire Extinguishing Systems - A valve assembly has a valve body having an inlet section for a pressurized fluid and an outlet. A piston is movable within the valve body between an open position and a closed position blocking fluid communication. The piston has an end section, a sealing section and a middle section located between the end section and the sealing section. A cavity receives the piston within the valve body. The cavity has a superior chamber, an intermediate chamber, and an inferior chamber. A spring within the superior chamber exerts a spring force onto the piston to urge the piston towards the open position. An actuator device provides upon actuation for a first flow of fluid outside the cavity from the inlet section to the superior chamber. The first flow causes a pressure within the superior chamber to increase until it is about the same as the pressure within the container so that the spring force moves the piston to the open position. In the open position a main flow of fluid flows from the inlet section via the intermediate chamber to the outlet. | 08-27-2009 |

Also included in the multipurpose fluid distribution system is a series of distribution valves operatively disposed between the water supply and the network of fluid distribution heads. The system can be controlled with a control unit associated with the distribution valves which is configured to automatically open select distribution valves or open select distribution valves according to manual input. The control unit is configured to open certain valves under predetermined conditions or upon a select schedule for the routine irrigation of the landscape with water from the water supply. In addition, the control unit is configured to open select distribution valves for the nonroutine application of water to the landscape in the event a humidity sensor or fire sensor associated with the control unit detects an approaching wildland fire. | 01-07-2010 |
