Fireball generator

A fireball generator device comprising a steel cylindrical main housing having first and second threaded end caps. A shotgun shell is encased in a barrel member and locked in place with a screw-on housing. When the shell is fired, the gases expelled by the shell push a knife blade forward into a gas container positioned within the main housing. The moving knife blade ruptures the gas container and the gas therein escapes and the powder gas from the shotgun shell ignites the gas escaping from the container creating various visual effects, such as a fireball.

Controlled triggering cutting off device

The invention relates to a device for cutting-off building parts made of concrete, that comprises a tank (10) in which an overpressure is generated by a gas generation effect due to a chemical reaction occurring after a predetermined period between a chemical compound and an aqueous solution. The tank (10) contains the aqueous solution, and is connected to an envelope (12) divided into a first housing (24) for storing the chemical compound and a second housing (25) containing an electronic trigger (11). A lid (23) is provided between the first housing (24) and the tank (10) in order to ensure a total tightness between the chemical compound and the aqueous solution in the absence of an initiating instruction of the trigger (11). An actuator (32) comprising a pyrotechnical priming head (40) causes the explosion of the lid (23) after a predetermined time-out, thus resulting in the chemical reaction inside the tank (10).

HYBRID GENERATOR WITH PERFORATOR PILLAR

STACKABLE PROPELLANT MODULE FOR GAS PRODUCTION

Cette divulgation décrit un module d'agent propulseur empilable pour une utilisation à l'intérieur d'une cartouche de production de gaz. Les modules sont conçus pour leur permettre d'être individuellement allumés plutôt que sous forme d'une masse unitaire, comme c'est le cas dans les configurations classiques. Ceci permet la génération d'un profil de pression contrôlée plutôt que d'un profil de pression non contrôlée déterminée par les conditions environnementales au fond du puits, telles que la température et la pression. This disclosure discloses a stackable propellant module for use within a gas production cartridge. The modules are designed to allow them to be individually lit rather than as a unitary mass, as is the case in conventional configurations. This allows generation of a controlled pressure profile rather than an uncontrolled pressure profile determined by environmental conditions at the bottom of the well, such as temperature and pressure.
