20110005780 | FIRE SUPPRESSOR CYLINDERS WITH ENHANCED BUBBLE PRODUCTION - A fire suppression cylinder includes a valve at an outlet of a canister, and a control for the valve. The canister receives a liquid suppressor agent and a pressurized gas. A feature within a portion of the canister will receive the liquid suppressor agent. The feature increases the formation of gas bubbles within the liquid suppressor agent. | 01-13-2011 |
20110083864 | FIRE SUPPRESSION SYSTEM - A fire detection system includes a detection tube and a sensing device. The detection tube contains a sensing fluid having a first physical condition and a second physical condition. The sensing fluid is in the first physical condition below a temperature threshold, and is in the second physical condition above the temperature threshold. The sensing fluid is at least partially liquid in the first physical condition. The sensing device is movable to open in response to a transition of a portion of the sensing fluid from the first physical condition to the second physical condition. | 04-14-2011 |
20110138880 | SENSOR APPARATUS AND METHOD THEREFOR - A sensor apparatus includes a metal oxide semiconductor (“MOS”) sensor with a gas-sensing surface normally having a first sensitivity to a first species of flammable gas and a second sensitivity to a second, different species of flammable gas. A selective sensitivity-enhancement layer is disposed on the gas-sensing surface such that the first sensitivity becomes increased and the second sensitivity remains substantially unchanged. | 06-16-2011 |
20110138881 | SENSOR APPARATUS AND METHOD THEREFOR - A sensor apparatus includes a metal oxide semiconductor sensor and a housing having an internal chamber in which the sensor is disposed. The housing includes at least one window for the ingress of a gas into the internal chamber from an atmosphere exterior to the housing. A gas-selective barrier is disposed across the at least one window. | 06-16-2011 |
20110297401 | SMOKE DETECTOR SYSTEM - A smoke detector system includes a smoke detector sensor and oxygen sensor mounted to a housing. | 12-08-2011 |
20120012346 | ODORANT FOR FIRE SUPPRESSION SYSTEM - A method for protecting a user in an enclosed environment includes providing an enclosed environment that holds cargo that has first odor; flowing a gas to the enclosed environment; and adding an odorant having a second odor to the gas, the first odor being distinctive from the second odor such that a presence of the second odorant provides a warning that the gas is present. | 01-19-2012 |
20120217027 | EXTENDED DISCHARGE OF ODORANT - A method for fire suppression includes flowing a first inert gas output into an enclosed space at a high rate of discharge and flowing a second inert gas output into the enclosed space at a low rate of discharge. The method further includes metering an odorant into the second inert gas to provide an extended warning that inert gas is present in the enclosed space. | 08-30-2012 |
20120217028 | ACTIVE ODORANT WARNING - A fire suppression and warning system for an aircraft includes an inert gas delivery system, an inert gas indicator, an on-ground indicator, and a warning device. The inert gas delivery system delivers an inert gas output to an enclosed space on the aircraft. The inert gas indicator signals that the inert gas delivery system has delivered the inert gas output to the enclosed space. The on-ground indicator signals that the aircraft is located on the ground. The warning device actively warns that the inert gas output is present in the enclosed space in response to a signal from the inert gas indicator and a signal from the on-ground indicator. | 08-30-2012 |
20120279732 | MANUAL RELEASE FOR A PYROTECHNICAL ACTUATOR FIRED BY A PIEZOELECTRIC GENERATOR OR IGNITER - A fire extinguishing apparatus has a structure defining a first chamber containing an electrically operable explosive device, a piezoelectric cell capable of producing an electrical output in response to a mechanical force upon the piezoelectric cell electrically connected to the electrically operable explosive device, a container of fire suppressant in contact with the structure, and a mechanical mechanism adjacent the piezoelectric cell for producing the mechanical force on the piezoelectric cell. The mechanical force produced by the mechanical mechanism is applied to the piezoelectric cell to produce the electrical output that actuates the electrically operable explosive device. | 11-08-2012 |
20140177675 | HEAT DETECTOR WITH SHAPE METAL ALLOY ELEMENT - A temperature sensing system comprises a conductive tube, a shape memory alloy (SMA) element, and a detector. The SMA element is disposed to create an electrical contact with the electrical tube when subjected to at least a critical temperature, and the detector is configured to identify an alarm condition when the conductive tube and the SMA element form a closed electrical circuit. | 06-26-2014 |
20140261748 | VALVE MECHANISM WITH FRANGIBLE PLUG - A valve mechanism is herein described that utilises a frangible plug. The valve mechanism comprises a valve body having an inlet port and an outlet port and a passageway extending therebetween. The valve mechanism comprises a frangible plug that is held within the valve body to block the passageway when the plug is intact. The plug comprises a predefined fracture plane and is configured to fracture across the predefined fracture plane upon application of an impact force. | 09-18-2014 |
20140318259 | METHOD OF MANUFACTURING A PRESSURE SENSOR - A method of manufacturing an overheat or fire alarm detection system, comprises the steps of micromachining a pressure sensor and securing a sensor tube in fluid communication with the pressure sensor. The sensor tube may comprise a hollow tube containing a material that evolves gas upon heating. The micromachining step may comprise doping at least a portion of a first layer, forming a cavity at least partially within the doped portion and forming a deformable diaphragm over the cavity. | 10-30-2014 |
20140320292 | PNEUMATIC PRESSURE SWITCH - A pneumatic pressure detector comprises a first electrical terminal, a second electrical terminal and a deformable diaphragm configured to deform between first, second and third positions. When the diaphragm is in its first position, the first and second terminals are open. When the diaphragm is in its second position, the first terminal is open and the second terminal is closed. When the diaphragm is in its third position, the first and second terminals are both closed. The pneumatic pressure detector may be connected to a sensor tube. | 10-30-2014 |
