Abstract: Included are methods and systems for enhancing recovery of a hydrocarbon fluid. An example method includes selecting a liquefied natural gas capable of being processed into a modified liquefied natural gas having a desired composition and adjusting the composition of the liquefied natural gas to provide the modified liquefied natural gas with the desired composition. The method further includes preparing a treatment fluid from the modified liquefied natural gas, introducing the treatment fluid into a wellbore, and contacting the hydrocarbon fluid with the treatment fluid in the wellbore.

Abstract: A single-point munition arming interface provides a more efficient approach to arming a canister-based munition. The single-point munition arming interface interfaces with electrically-initiated canister-based munitions. The arming interface locks and arms munitions in a baseplate system before initiation. The single-point munition arming interface includes a feature for removing the first safety in the munitions safe and arm device which is actuated upon insertion of the munition into the interface. The second step in the procedure is a user action which simultaneously locks the munition to the interface and completes the arming sequence by using a single mechanism to achieve both essential motions. The arming interface can be mechanically or electrically actuated allowing for remote activation which increases operator safety.

Abstract: A pneumatic launch system includes a manifold that stores pressurized gas and releases the pressurized gas on command to sequentially open the store retention hooks and eject the store. The manifold includes an eject valve whose main chamber is part of the high pressure gas storage. A hook release valve is controlled by the eject valve for sequential operation of hook opening and store ejection. A manually selectable pitch valve provides pitch setting to proportion the gas delivered to the ejector cylinders. The manifold minimizes flow path restrictions and provides a fast actuation response with minimum variability to unlock the hooks and quickly eject the store.

Abstract: The present invention relates to a penetration assistance kit fitted to a bomb, notably an anti-infrastructure bomb. The kit includes launch tubes mechanically secured to the bomb. In each of the launch tubes is positioned a detonating projectile and its propulsive charge. A detonating projectile can be ejected from its tube by initiation of its propulsive charge. A system is provided for controlling the initiation of each propulsive charge prior to impact of the bomb with a target. The invention applies notably to the penetration of very thick walls made of non-metallic material such as concrete, for example. The invention also relates to a penetrating projectile equipped with such a kit and to a method of getting such a projectile to penetrate a target.

Abstract: A kinetic energy penetrator includes a plurality of penetrator segments, a penetrator segment sleeve for storing the plurality of penetrator segments, and means for moving the plurality of penetrator segments from the penetrator segment sleeve to locations substantially aligned along an axis of attack. A method includes storing a plurality of penetrator segments away from an axis of attack and moving the plurality of penetrator segments to locations substantially aligned along the axis of attack. A vehicle includes a body and a kinetic energy penetrator disposed in a forward portion of the vehicle. The kinetic energy penetrator includes a plurality of penetrator segments, a penetrator segment sleeve for storing the plurality of penetrator segments, and means for moving the plurality of penetrator segments from the penetrator segment sleeve to locations substantially aligned along an axis of attack.

Abstract: An explosively driven impactor grenade includes a grenade body having a substantially spherical shape and a hollow central portion, the grenade body including a plurality of recesses formed on an external surface thereof with each recess including an opening into the hollow central portion of the grenade body, the grenade body including an opening on the exterior surface that connects with the hollow central portion; a fuze disposed in the hollow central portion of the grenade body; a fuze cap for closing the opening on the exterior surface that connects with the hollow central portion; and a plurality of explosively driven impactors respectively disposed in the plurality of recesses formed on the external surface of the grenade body, the explosively driven impactors being connected to the fuze through the recess openings into the hollow central portion of the grenade body.

Abstract: This invention relates to a releasable body, comprising outspreadable arms articulated at one of the ends of said body and actuation means adapted to pass said arms, in the course of aerial descent of said body, from a position folded along said body to a spread out position substantially perpendicular to said body in order to brake descent thereof, wherein it comprises first means for controlling said actuation means to control retraction of said arms along said body when the latter has reached the ground after its aerial descent, said body then being in standby state, and second means for controlling said actuation means to control outspreading of said arms to pass from the standby state to an active state in which the arms support the body on the ground. The invention is applied to releasable bodies provided with aerodynamic braking means.

Abstract: A forest fire extinguishing device comprising a projectile filled with an inert gas under pressure which is dropped into a fire and automatically disperses the gas. When the device impacts the ground, a plurality of ports are simultaneously opened, allowing the fire extinguishing material to be expelled over a prescribed area.
