| 20120120416 | SYSTEM FOR DETERMINING THE LENGTH OF AN OPTICAL FIBER UNWOUND FROM/REMAINING ON A STORAGE REEL PARTICULARLY HOUSED IN AN UNDERWATER WEAPON - A system is provided that determines the length of an optical fiber unwound from or remaining on at least one storage reel. The fiber is used as a medium for transmitting information between a weapon and an underwater vehicle, from which the weapon was fired. The determination system measures the backscattered light power in the fiber, analyzes this power signal in order to detect a backscattered light power discontinuity that corresponds to the location of the fiber where the fiber leaves the reel, localizes this location along the fiber, and determines from this localization and from the length of fiber initially wound on the reel, the length of fiber unwound from or remaining on the reel. | 05-17-2012 |
| 20120094202 | DEVICE FOR PRODUCING ELECTRICITY FOR A SUBMARINE COMPRISING A FUEL CELL - The invention relates to a submarine comprising a device for producing electricity including a fuel cell, means for feeding oxygen gas, means for feeding hydrogen fuel, and means for discharging the gas effluents, characterized in that the fuel cell ( | 04-19-2012 |

| 20110191061 | SYSTEM FOR INSPECTING A HULL OF A SHIP AND ASSOCIATED METHOD - A system for inspecting the hull of a vessel includes a movable machine which moves on the hull and a positioning element to determine an instantaneous position of the machine in a reference point. The positioning element includes: —first and second coaxial encoding wheels separated from each other by an inter-wheel spacing and in contact with the hull, and are capable of measuring first and second linear movements of the machine; —first and second inclinometers arranged so as to measure inclinations, relative to a reference direction, of a first axis and a second axis of a frame of reference linked to the machine; and, —a processing element, which receives data measured in order to calculate a variation of the position of the machine in the frame of reference, and in order to integrate the successive position variations in order to obtain the instantaneous position of the machine. | 08-04-2011 |
| 20110167995 | PRINCIPLE FOR THE INTEGRATION OF MISSILE-BASED WEAPON SYSTEMS ON A FIXED RAMP FOR STEALTH SURFACE VESSELS IN ORDER TO COUNTER ASYMMETRIC THREATS - Device for launching missiles from a ship, includes at least one missile launch ramp, includes a ditch delimited by side walls of which at least two constitute bulwarks which extend around the periphery of the ship, the ditch being open above the exterior deck of the ship, in that the launch ramp is positioned in the ditch so it can be used to launch a missile over a lateral bulwark of the ditch extending around the periphery of the ship. It includes an element for discharging the missile propulsion gases including a duct opening onto an orifice in a lateral bulwark of the ditch extending around the periphery of the ship, and the lateral bulwarks of the ditch are of a height tailored to conceal the missiles in place on the ramp, for angles of incidence of between 0 and −5° with respect to the deck of the ship. | 07-14-2011 |

| 20090220390 | DEVICE FOR GENERATING HYDROGEN FROM HYDROCARBON, WATER AND OXYGEN COMPRISING A REACTION AND HEAT EXCHANGE CHAMBER - A device generating hydrogen from a hydrocarbon, oxygen and water. The reaction is carried out at high temperature. The device includes a first substantially cylindrical zone surrounding the reaction chamber circulates water vapour and hydrocarbon, excluding the reaction products, the zone being separated from the reaction chamber to recover heat lost by the reaction chamber, to preheat the mixture circulating in the first zone. The reagent(s) are in contact with the walls of said first zone to exchange produce heat. A substantially cylindrical second zone surrounds the first zone and circulates water to be vaporized, the water is in contact with the walls of said second zone. The first and second zones are separated such that water circulating in the second zone is preheated by heat of the first zone where the water of the second zone is mixed with the hydrocarbon and introduced into the first zone. | 09-03-2009 |
