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. |

An aerial fireworks display device includes a plastic bottle for holding a quantity of combustible liquid, such as diesel fuel, and a one piece plastic lid structure which is threadable onto the bottle and has an open-topped depending well portion in which a quantity of flash powder may be placed. After the flash powder has been placed in the lid well portion a fuse-containing plug structure is snap-fitted into the top end of the lid well. The diesel fuel is poured into the bottle and the lid is screwed onto the bottle so that the flash powder-containing well extends into the bottle interior, and a portion of the fuse extends outwardly through the upper end of the plug structure. The assembled device may then be inverted and placed in a mortar tube for launching. |

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. |

A remotely-actuated fireworks launcher apparatus includes a housing assembly, a signal receiver housed within the housing assembly, an ignition servo electrically connected to the signal receiver and housed with the housing assembly, and a servo-actuated ignition switch operated by the ignition servo. The servo-actuated ignition switch is in an ignition circuit which also includes an electric igniter assembly, and a power supply. A fireworks receiver assembly is attached to the electric igniter assembly. The fireworks receiver assembly receives a fireworks device that is ignited by the electric igniter assembly. A manually operated ignition signal transmitter is actuated to transmit signals for activation of the signal receiver. The servo-actuated ignition switch includes a first switching element operated by the ignition servo and a second switching element selectively connected to or disconnected from the first switching element. The signal receiver receives electromagnetic waves, and the manually operated ignition signal transmitter transmits electromagnetic waves. In a second embodiment, a receiver-tilt servo is controlled by the signal receiver. A manually operated tilt signal transmitter is actuated to transmit signals for activation of the receiver-tilt servo. A tilting assembly is connected between the receiver-tilt servo and the fireworks receiver assembly. A pivot assembly is connected between the housing assembly and the fireworks receiver assembly. The receiver-tilt servo receives electromagnetic waves, and the manually operated tilt signal transmitter transmits electromagnetic waves. |

A pyrotechnic device comprises a receptacle which contains a charge of pyrotechnic material and an electric fuse to initiate the charge. The receptacle is formed of a plastics housing which has an area formed of lines of weakness adapted to rupture on activation of the pyrotechnic material and a closure having an integrally moulded projection which defines a screw-thread, electric contacts being associated with the projection and trapping the bared ends of wires associated with the fuse. |

A blast simulator for use as a noise environment tester in a simulated mile launcher. The blast simulator includes a cylinder capped at both ends by a paper disc and encloses a pyrotechnic charge. An electric squib is inserted through either the cylinder walls or the end discs and when actuated ignites the pyrotechnic charge. |
