| 20110163841 | TEMPERATURE SWITCH - A temperature switch comprises a material ( | 07-07-2011 |
| 20110036599 | EXTINGUISHING FIRES AND SUPPRESSING EXPLOSIONS - A fire extinguishing or explosion suppression device comprises a chamber and a nozzle. The nozzle defines a discharge pathway from the chamber. The chamber has an inlet for pressure-driven introduction of a liquid into the chamber. The chamber is shaped so that a gas contained in the chamber before the introduction of the liquid is entrained into the liquid during the pressure driven introduction of the liquid such that a mixture of the liquid and the gas is discharged through the nozzle to create a mist for extinguishing a fire or suppression of an explosion. After the gas has been discharged from the chamber, the nozzle produces a spray having a core of larger liquid droplets with the core being surrounded by smaller liquid droplets. | 02-17-2011 |
| 20100276625 | FIRE FIGHTING FOAMING COMPOSITIONS - In a first aspect a fire fighting foaming composition contains a partially acetylated polyvinyl alcohol. In a second aspect the fire fighting foaming composition contains chitosan together with a surfactant such as a protein derived surfactant or a hydrocarbon surfactant which is either amphoteric or non-ionic. The compositions can form effective fire fighting foams in the absence of fluorinated surfactants and other fluorinated compounds. | 11-04-2010 |
| 20090072981 | FIRE DETECTION - A fire detection system for monitoring a volume containing fluid, typically air, for the presence of smoke particles is disclosed. A conduit for receiving the fluid, and any smoke particles therein, and directing the fluid to a smoke detector has a plurality of inlets formed therein. A respective temperature sensor is associated with each of the inlets which generate a signal indicative of a change in temperature in the region of the inlet. In the embodiments, the temperature sensor comprises one or more fibre Bragg gratings. The fibre Bragg gratings preferably have different grating periods. The reflected light from each fibre Bragg grating is returned back down the fibre optic cable and redirected via a 2×1 coupler to a wavelength detection system and a personal computer. The combination of wavelength detection system and personal computer allow analysis of the reflected light patterns, as well as providing a user interface which enables detection of the occurrence of a spatial and/or a temperature variation. The location of the said variation along the fibre optic cable is advantageously detectable. The system described is highly sensitive to smoke, but can advantageously also provide an indication of the location of the smoke source, because any variation in temperature at any one of the smoke inlets is also detected, the location of the sensor being known. | 03-19-2009 |
