20090301735REMOTE CONTROLLED NOZZLE CHANGER - A fire fighting fluid delivery device includes a device body with an inlet, a discharge outlet, and a fluid passageway extending between the inlet and the discharge outlet. A movable member is mounted at the body and movable between at least two positions relative to the outlet. The movable member includes at least two spaced apart transverse openings, with each of the transverse openings for selectively aligning with the discharge outlet when the movable member is moved between the at least two positions.12-10-2009
20080283255Liquid 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
20090211771Regulated 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
20110186310SPRAY HEAD - The present invention provides a sprinkler head for mounting on a pipe of a fire protection system, in particular for dispensing an extinguishing agent, the head comprising: a body having a transfer channel passing therethrough; and an endpiece comprising a base having an outlet channel passing therethrough, and a shutter closing said outlet channel, the endpiece in a “closed” position closing the transfer channel and being suitable for disengaging said transfer channel under the effect of an opening force of less than 1500 N.08-04-2011

20120160525VIDEO-BASED FIRE DETECTION AND SUPPRESSION WITH CLOSED-LOOP CONTROL - A closed-loop system employs video analytic outputs in a feedback loop to control the operation of a video-based fire detection system. In particular, video data captured by a video detector is analyzed by a video analytic system to generate outputs identifying regions indicative of fire. These outputs are employed as feedback in a closed-loop control system to orient the camera such that field of the view of the camera is modified to improve the ability of the video analytic system to verify or confirm the presence of fire within a region identified as indicative of fire. In addition, video analytic system may generate outputs identifying the delivery location of a fire suppressant. These outputs are employed as feedback in a closed-loop control system to orient the delivery of suppressant to extinguish the fire.06-28-2012
