With Means To Eject Flare From Casing Patents (Class 102/342)
  • Patent number: 6286429
    Abstract: A longitudinal launcher tube made substantially of polyurethane resin or plastic having a rear end closed by a transverse rear wall and an open front end. The invention allows a projectile to be housed in the tube and adapted to slide longitudinally inside it towards the front, to be expelled from it via the front end tube, means for defining with the tube and projectile a rear gas expansion chamber immediately to the rear of the projectile, and an impulse cartridge adapted on command to develop gas pressure in the rear chamber to cause the expulsion of the projectile via the front end of the tube. The apparatus is a pyrotechnic device for rigidly supporting fireworks such as mortar-type, rocket-type, projectile-type, and other pyrotechnic devices so that the launcher device is reusable, whereby the launcher substantially retains its integrity after each launch to minimize harm caused to persons and the environment.

  • Patent number: 6244185
    Abstract: A skyrocket is provided which provides a first fireworks effect prior to launch as well as a second effect after launching. The skyrocket includes a body which houses or is coupled to a rocket motor, a first effect and a second effect. A transparent or translucent nose cone is placed on the top end of the body which provides both the ability to view one of the effects placed therein but also maintains the aerodynamic properties of the skyrocket. The first effect may be a strobing effecting which during burning provides a pulsating intensity of light visible through the nose cone prior to lift-off of the skyrocket, and the second effect may be a bursting charge which explodes after the rocket is in flight. An ignition fuse leads to the first effect and a second fuse leads to the rocket motor so that by lighting the first fuse, no further fuses need be lit and a delay is provided before the rocket motor ignites.

  • Patent number: 5979328
    Abstract: An apparatus for the deployment of a visible plume to alert other motorists that a proximate motor vehicle has been involved in a collision is described as having a tube which is open at one end disposed at the top and closed at a distal end. The distal end houses an activation device that is used to detonate an explosive charge in response to the detection of an output signal. The output signal is generated by a sensor subsequent to the motor vehicle experiencing an impact of sufficient magnitude. Both the sensor and the output signal are compatible with current technologies used to detect impacts which result in the deployment of air bags, and accordingly the device may rely upon these systems as may already be installed in the motor vehicle. The explosive charge expels a signaling media above the motor vehicle in a plume above the motor vehicle to visually alert other motorists that a collision has occurred.

  • Patent number: 5739462
    Abstract: A pyrotechnic device includes a launcher for launching and igniting a plurality of pyrotechnic stars for creating an aerial fireworks display. The launcher comprises a launching tube having an igniter that ignites the pyrotechnic stars as they are being expelled from the launching tube under the force of pressurized air. The igniter may comprise a section of the launching tube having a locally reduced diameter so that the pyrotechnic star frictionally engages it during launch, causing a striker composition on the interior of the launching tube to ignite a prime composition on the exterior surface of the pyrotechnic star. Alternatively, the igniter may comprise a flame within the launching tube to ignite the prime composition on the star. Various feeding mechanisms are provided to rapidly feed a large number of pyrotechnic stars for launching from the launching tube. The launcher utilizes pressurized air to launch the pyrotechnic stars and, thus, minimizes adverse environmental impact.

  • Patent number: 5616884
    Abstract: A propellant system is disclosed which includes a propellant applied to at least one surface of a substrate which is in the form of a strip. The propellant strip is adhesively attached to itself in a configuration which conceals propellant within the configuration and which allows the attached strip to peel away from itself under applied forces thereby resulting in smooth and continuous exposure of propellant for burning. The system is directed to use with ejectable projectiles which are slidably disposed within a canister or casing. The propellant system is interconnected between the projectile and the cannister which houses the projectile. The propellant is urged to peel, and thus expose propellant for burning, as the projectile is ejected from the canister. Alternatively, the propellant is telescoped and covered with a sleeve which peels away as the projectile is ejected.

  • Patent number: 5551345
    Abstract: A smoke screen shell is provided having a rapidly burning decoy charge that generates a spontaneous fog and a slowly burning camouflage charge that generates a lasting fog. The decoy charge and camouflage charge are fired from a canister sleeve by an ejection charge. Upon firing, pressure from the ejection charge is communicated through a channel to a relief chamber positioned between the decoy charge and the camouflage charge. This results in an accelleration difference, causing a separation and slightly different trajectories, the decoy component accelerating at a higher rate. The decoy charge takes effect in the air prior to the camouflage charge. The collocation of the spontaneous fog and of the lasting fog essentially occurs in the target. The decoy charge and the camouflage charge land within a proximity at a target area such that a collocation occurs between the spontaneous fog and of the delayed lasting fog.

    Abstract: A combustible ignition system for use in an illuminating flare warhead. The ignition system includes a pickup charge positioned contiguous the separation charge of the ignition initiator. The pickup charge is positioned such that the firing of the separation charge triggers combustion of the pickup charge. The pickup charge extends to a combustible train which comprises a continuous thin-layer explosive composition positioned within a plastic tubing. The firing of the pickup charge creates sufficient shock that the combustible train is detonated. The combustible train extends along the flare casing adjacent the parachute system and the illuminant. At the head end of the warhead, the explosive train connects to an output charge. The explosive shock of the explosive train is sufficient to detonate the output charge. The output charge transfers the combustion to a BKNO.sub.3 pellet basket within the illuminant igniter of the warhead.
