Abstract: The invention relates to a missile container retaining structure (1a) for a missile launch device of the type comprising a plurality of cells for receiving a missile container (2) and at least one duct (3). The structure is constituted by metal plates (101, 104) which are pre-cut so as to comprise complementary elements which can be fitted one inside the other, the plates being assembled so that the complementary elements of two adjacent plates are fitted one inside the other.

Abstract: A weapon storage device (10) which is to be attached to an external face (8) of a hull (4) of a submarine (2) and which is capable of containing weapons (14), such as ammunition or weapon carriers, which are to be deployed from the storage device on receipt of a deployment signal transmitted from inside the submarine, includes a compensation element (16, 18, 30, 40) which allows the variation in mass of the storage device (10) resulting from the deployment of at least one weapon to be compensated for, partially or wholly, by replacing a volume of gas initially contained in the storage device by an identical volume of water introduced into the storage device.

Abstract: The invention relates to a submarine (1) of the type that includes a bridge (4), a bridge fin (3) and a device (8) for releasing and recovering a secondary self-propelled underwater vehicle (90), said device (8) including a handling means (8A) which can be used to move the secondary underwater vehicle between a storage zone (18) and a release or recovery zone (19) and a reversible grip means (14) solidly connected to the handling means (8A), which can be used to free the secondary underwater vehicle (90) at the moment of release and to attach said vehicle at the moment of recovery. The release and recovery device (8) is designed such that the release and recovery zone is located outside the turbulent zone (7) that surrounds the moving submarine.

Abstract: 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.

Abstract: The invention relates to an armed stealth surface vessel (1) comprising a hull (2), a deck (5, 6) and superstructures (3). The inventive vessel is equipped with sensors, transmitters, arms and, optionally, handling means. The invention is characterised in that the outer casing (4) of the deadworks comprises walls which are all inclined inwards such that the outer faces thereof are oriented upwards and form an angle that is greater than or equal to 20° with the vertical at least above a line located 5 m above the waterline and, along at least 50% of the length of the vessel, above a line located less than one metre above the waterline. The invention is also characterised in that that the essentially-vertical joint lines between two adjacent walls are inclined inwards and form an angle of more than 20° with the vertical. The invention is further characterised in that the sensors and transmitters, the arms and the handling means are concealed or can be concealed in or under the outer casing of the deadworks.

Abstract: A ship hull includes at least one float (10) and a centre of buoyancy (CB) situated behind the centre of flotation (CF), the distance between the centre of buoyancy and centre of flotation is greater by 5% than the waterline length L of the hull.

Abstract: A device (12) for interfacing an external peripheral unit (18) to a store controller (16) and store terminal (14) of a point of sale (POS) system has been provided. The interface device includes an MPU (50) for passively monitoring the data coming from the store terminal without causing any interruption to the POS system. When a specific key sequence indicative of a request for use of the peripheral unit has been detected, the device interrupts the flow of data between the store controller and store terminal and enables the MPU to now send data to the store controller and store terminal. Additionally, the device provides a plurality of data paths for allowing the MPU to read data from the store terminal, for storing and reading data from the store controller, and for transferring data between the MPU and the peripheral unit.
