Patent number: 7886837Abstract: An external sprinkler system for use on homes is herein disclosed. It is designed to prevent the ignition of the roof structure from glowing ashes or embers from a nearby wild fire or structure fire. The sprinkler system would use a series of nozzles connected to a common manifold and integrated therein a building structure's roof vents. The piping connecting the manifold is connected to a water supply via a control valve mounted at grade level. Control equipment provides switching between a public water supply and home cisterns. Runoff water is captured by the existing gutter system and recycled through the system. During activation, the system soaks the roof and house and makes it very difficult for ignition from an external source to take place. The system provides manual activation and remote activation from a cell phone or fire station.Type: GrantFiled: November 27, 2007Date of Patent: February 15, 2011Inventor: Hans E. W. Helfgott

Patent number: 7878258Abstract: The invention relates to a fire protection installation (30) comprising a mist sprayer system with at least one nozzle (5, 10) through which extinguishing medium in the form of liquid is arranged to be sprayed out at high pressure, so that a mist is created for achieving fire extinguishing by means of cooling of combustion gases and the seat of the fire. The distinguishing characteristics are that the fire protection installation is portable and has a modular construction comprising a basic system (31) and a number of customized additional systems, which additional systems comprise different additional units that are adapted to a particular function profile that is set in the actual fire protection installation.Type: GrantFiled: February 9, 2006Date of Patent: February 1, 2011Inventors: Torbjörn Lindström, Björn Lundblad

Patent number: 7857069Abstract: A method for activating a sprinkler system comprises maintaining a liquid extinguishant in system pipes under a standby pressure that is less than the operating pressure, determining an arrangement of the sprinklers that will control a fire, and opening the sprinkler system valve in response to a drop in pressure in each of the pipes to which at least one of the sprinklers of the arrangement is connected. An alternate method comprises providing a bypass around the system valve, and opening the system valve in response to (1) a predetermined flow of liquid extinguishant through the bypass and (2) a drop in pressure in the sprinkler system below a predetermined pressure. In a variation of the alternate method, the system valve is opened in response only to a predetermined flow of liquid extinguishant through the bypass.Type: GrantFiled: December 5, 2006Date of Patent: December 28, 2010Assignee: FM Global Technologies LLCInventor: Hong-Zeng Yu

Patent number: 7849931Abstract: An integrated environmental control system for a cargo stowage compartment in a mobile platform, for example in a commercial passenger jet aircraft. A fire detection/suppression subsystem is integrated together with an airflow management system. The airflow management system operates to circulate, and optionally to heat or cool, air withdrawn from a cargo stowage compartment of the aircraft before the air is released back into the cargo stowage compartment. A fire suppression substance, for example, Halon gas, can be discharged directly into a recirculation duct of the airflow management system, thus reducing the duct work required to achieve fire suppression and ventilation operations for the cargo stowage compartment. The integration of the fire detection/suppression and airflow management system operations reduces the overall amount, complexity and weight of the ducting employed in a cargo stowage compartment of a commercial jet aircraft.Type: GrantFiled: September 7, 2006Date of Patent: December 14, 2010Assignee: The Boeing CompanyInventor: Casey Y.

Patent number: 7836966Abstract: An arrangement for testing a fire suppression sprinkler system includes a conduit for supplying a flow of fire suppression fluid to at least one sprinkler. A sensor is configured to sense the flow of the fire suppression fluid to the at least one sprinkler. The sensor has a first condition indicative of a predetermined volume of flow of the suppression fluid to the at least one sprinkler and a second condition indicative of a volume of flow of the fire suppression fluid to the at least one sprinkler less than the predetermined volume of flow. An actuator causes the sensor to be in the first condition or the second condition. A signaler provides an indication to a user that the sensor is in at least one of the first condition and the second condition.Type: GrantFiled: January 28, 2008Date of Patent: November 23, 2010Assignee: AGF Manufacturing, Inc.Inventors: George J. McHugh, George McHugh, IV, legal representative, George McHugh, IV, James P. McHugh

Patent number: 7823650Abstract: A hazard control system according to various aspects of the present invention is configured to deliver a control material in response to detection of a hazard. In one embodiment, the hazard control system comprises a pressure tube having an internal pressure and configured to leak in response to exposure to heat. The leak changes the internal pressure and generates a pneumatic signal. A fire detector may also detect a fire condition associated with fire. A valve may be coupled to the fire detector and the pressure tube. The valve is configured to change the internal pressure and generate the pneumatic signal in response to a signal from the fire detector. The pneumatic signal triggers a delivery system to deliver the control material.Type: GrantFiled: July 11, 2008Date of Patent: November 2, 2010Assignee: Firetrace USA, LLCInventors: William A. Eckholm, Lee Seebaluck
