20110168416 | HIGHLY INTEGRATED DATA BUS AUTOMATIC FIRE EXTINGUISHING SYSTEM - A fire extinguishing system includes a first data bus having respectively first power and command leads. The system has multiple zones, each of which may include one or more detectors, and/or one or more suppressors and activation devices. The first data bus is directly connected and common to the detectors, suppressors and activation devices. A controller is connected to the multiple zones via the first data bus. A fire activation module includes the actuation device. First and second power leads are connected to the actuation device. A capacitor is connected to the actuation device and the power leads. The capacitor is configured to store electricity from the power leads and discharge the electricity to the actuation device during a suppression event. A wiring harness provides a zone identification element in communication with a connector and configured to provide a zone location assignment to the connector. | 07-14-2011 |
20130032741 | SUPPRESSANT ACTUATOR - An exemplary suppressant actuator assembly includes a release member movable from a first position that restricts flow of a suppressant to a second position that permits flow of a suppressant. A biasing member moves from a more-biased position to a less-biased position to move the release member from the first position to the second position. A solenoid is activated to permit movement of the biasing member. | 02-07-2013 |
20130186654 | MULTIPLE DISCHARGE FIRE EXTINGUISHING SYSTEM - A fire extinguishing system for use in a crew compartment of a ground-based vehicle includes at least two cylinders. The cylinders dispense a fire extinguishing agent through a release mechanism. A control for the overall system is operable to actuate the two cylinders. A nozzle is positioned downstream of the release mechanism to distinguish the extinguishing agent into the crew compartment. The majority of the dispensing from at least a first of the two cylinders occurs in less than five seconds. | 07-25-2013 |
20140048292 | HIGHLY INTEGRATED DATA BUS AUTOMATIC FIRE EXTINGUISHING SYSTEM - A fire activation module for a fire extinguishing system includes an actuation device that has an instantaneous actuation current draw during a suppression event. First and second power leads are connected to the actuation device and have a current capacity less than the instantaneous actuation current draw. At least one capacitor is connected to the actuation device and the power leads. The capacitor is configured to store electricity from the power leads and discharge the electricity to the actuation device during the suppression event. | 02-20-2014 |
20140048330 | HIGHLY INTEGRATED DATA BUS AUTOMATIC FIRE EXTINGUISHING SYSTEM - A wiring harness for a fire extinguishing system including a connector that has a pair of power leads and a pair of command leads. At least one zone identification element is in communication with the connector and is configured to provide a zone location assignment to the connector. | 02-20-2014 |
20140262723 | PNEUMATIC DETECTOR INTEGRATED ALARM AND FAULT SWITCH - An integrated switch to indicate pressure changes in an environment includes a housing with a cavity between a first retainer portion and a second retainer portion, a first diaphragm held in the cavity of the housing to indicate fault conditions, and a second diaphragm held in the cavity of the housing to indicate alarm conditions. | 09-18-2014 |
20150097677 | PNEUMATIC DETECTOR SWITCH HAVING A SINGLE DIAPHRAGM FOR ALARM AND FAULT CONDITIONS - A pneumatic pressure detector switch is disclosed that includes a retainer assembly adapted to communicate with a source of pressure, a deformable diaphragm supported within the retainer assembly and movable in response to changes in pressure communicated to the retainer assembly, a fault contact element supported by the retainer assembly adjacent a first side surface of the diaphragm, and an alarm contact element supported by the retainer assembly adjacent a second side surface of the diaphragm. | 04-09-2015 |
20150107685 | POPPET VALVE WITH A FRANGIBLE SEALING DISC FOR A PRESSURE VESSEL - A valve assembly for a pressure vessel is disclosed that includes a valve housing operatively associated with an outlet of the pressure vessel, a frangible hermetic disc sealing the outlet of the pressure vessel, and a poppet valve mounted for movement within the valve housing between a first position supporting the frangible hermetic disc within the outlet of the pressure vessel and a second position spaced apart from the frangible hermetic disc to permit the frangible disc to burst under pressure and permit the egress of pressurized material from the pressure vessel through the outlet. | 04-23-2015 |
