Abstract: Munitions are dropped from military aircraft to quickly combat large area fires within vast threatened regions. Each munition has a shell-shaped case having a chamber containing an air-bag power module and fire retardant. A lid closes one end of the chamber, and switches on the case provide signals for the air-bag power module to suddenly forcefully displace the lid from the chamber by the air-bag module and suddenly forcefully eject the fire retardant from the chamber and out of the case by the air-bag module. Munitions containing fire retardant can be targeted accurately at single hot spots, isolated structures, and along fire lines or can be quickly and accurately dropped to create a protected zone behind an area that has been made not to burn by munitions to protect fire fighters trapped in the path of runaway fires. Munitions are deployed from aircraft by military crewmen without requiring additional training.

A drill, with a power device, is connected to the opposite end of the cylinder setup and cylinder mast's weapon container for drilling a hole into the earth.

Abstract: Shell for trench mortars and similar firing systems, which shell includes an effective portion, which can be fired from a barrel by a propellant charge, there being a pressure plate provided between the effective portion and the propellant charge, which pressure plate carries the influence from the propellant charge. To provide effective fire above the ground a support portion is releasably arranged in front of the effective portion in the firing direction. The support portion carries a second propellant charge and in its front end a percussion cap, which, when the shell is fired, is located partly exposed outside the front end of the support portion and initiates the second propellant charge when hitting ground.

Abstract: The spinning mine has all of its projectiles concentrated in one small ar It is launched from a spring-loaded threaded screw launcher and acquires angular momentum as it ascends into the air from the launcher to a pre-determined detonation altitude. As the mine spins, the detector assembly on board detects the presence and location of potential targets and sends appropriate indicative signals to a microprocessor, also on board. The microprocessor determines therefrom the location of the largest target or the largest cluster of targets in the environment and triggers the detonation of the mine such that the projectiles are jettisoned in a conical pattern toward the largest target or the largest cluster of targets for a more efficient destruction of the targets.

Abstract: To simulate the output of a laser to a Multiple Integrated Laser Engagement ystem (MILES), an electronic circuit having a PLL subcircuit and a microprocessor is used to detect an acoustic signal having a predetermined frequency and pulse rate. Upon detection of the correct acoustic signal, a prestored universal kill code is provided to an inductive loop magnetically coupled to the antenna coil of a harness to which the MILES is integrated. The thus received inductive signal is recognized by the MILES which in turn outputs an audio alarm to indicate that a kill has occurred.

Abstract: The invention relates to a mine with at least one ejectable sub-munitions body disposed in a cup-shaped starting device and with a propulsion device for propelling the sub-munitions body into a selectable altitude range. For achieving that the propulsion device requires only a small structural volume, entails low cost because of the use of reduced amounts of propulsion charges and in addition operates safely and dependably. It has been proposed to dispose the propulsion device not in or on the sub-munitions body, but in the bottom part of the cup-shaped starting device. In this case the propulsion device advantageously consists of a high pressure chamber facing the bottom of the starting device, in which the propellant charge is contained, and of a low pressure chamber facing the sub-munitions body. The high pressure and low pressure chambers are separated from each other by a perforated plate provided with jets (holes).

Abstract: A trip wire type mine has a plurality of trip wires, each trip wire being wound on a reel and ejected through an opening in a body of the mine by means of an ejection system. The ejection system may include a cutting device to cut a lid in a plate forming a plane wall of the hollow body of the mine, a movable system to displace the cutting device, and a pyrotechnic charge to drive the movable system. A projectile is attached to one end of each trip wire, and the charge is also used to eject the plurality of projectiles through the opening, thereby deploying the trip wires and placing the mine in an operational state.

Abstract: An area defense mine has an orientable launch tube to fire a projectile at any bearing angle. The projectile contains at least one explosive charge, an arrangement for spinning the projectile about an axis of rotation and a device for detecting a target. The launch tube is orientable according to at least two different angles of sight. An arrangement for positioning the projectile in the launch tube allows the projectile to be positioned on a sabot of the tube in such fashion that the axis of rotation of the projectile remains oriented at a given axis whatever the angle of sight selected. Such a mine can be used either in a short-range or in a medium-range operating mode.

Abstract: An acoustic training mine simulator system for use with the pre-existing tiple Integrated Laser Engagement System (MILES). The MILES, located on a target, responds to the acoustic output of said mine simulator upon simulated detonation. The MILES acoustic detection circuitry momentarily disconnects the MILES power supply from the rest of the MILES circuit, causing the MILES to generate an audible alarm indicating a target has been hit.

Abstract: A mine, particularly a land mine, is equipped with at least one active (i.e. destructive) element which is accommodated in a housing of the mine and can be brought to the functional level by means of a rocket engine. For attaining a definite ascent of the active element, the rocket engine is mounted to this active element in such a way, and is designed in such a way, that its exhaust nozzles are located outside the mine housing and the propellant gases of the rocket engine effect extraction of the active element from the mine housing which is open at an upper end. The rocket engine furthermore exerts preferably a torque on the active element about the longitudinal axis of the element so that, in conjunction with an effective charge, the effective direction of which is inclined obliquely downwardly, the effective area on the ground continuously increases in a spiral fashion during ascent of the active element.

Abstract: A proximity detector mine system comprises a mine depolyable on the ground and including a propellant device effective upon actuation to propel the mine above the ground, explosive material, a detonator for detonating the explosive material a predetermined time after the propellant has been actuated, a sound sensor producing electrical signals in response to the sound sensed thereby, and a processor for processing the electrical signals and for actuating the propellant device in response to the electrical signals received from the sound sensor.

Abstract: A treadle assembly for throwing armor piercing shaped charges or squash charges against the underside of armored vehicles has a tripping batten connected at an angle or cant to a lever arm or leg which leg holds an armor-penetrating munition on its far end. The batten and lever arm structure is such so that the munition is oriented in the correct direction when the assembly is deployed on the surface of the ground, such as a field or roadway. The munition has a firing pin which, when armed, extends upwardly to contact the underside of the armored vehicle when the vehicle wheel or tread pushes over the treadle plate thereby pivoting the lever arm and raising the munition.

Abstract: An arrangement in a mine which is capable of being neutralized, comprising detecting means (33) operative to detect a neutralization of the mine, and initiator means (3) adapted to initiate detonation of a spotter charge (5) incorporated in the mine in response to the detection of a neutralization, and a spotter (1) which is arranged to be propelled from the mine by said detonator charge to the surface of the ground, in order to disclose the location of the mine. A penetrator (4), which is intended to drive a pathway through the ground to facilitate passage of the spotter (1), is arranged forwardly of the spotter in the mine, as seen in its direction of travel. The spotter (1) is capable of forwardly driving the penetrator (4) during a first phase of the spotter firing sequence; and the arrangement further includes a separating device (9) which is intended to separate the spotter from the penetrator during a second phase of the firing sequence.
