Abstract: A conducted electrical weapon (“CEW”) impedes locomotion of a human or animal target by providing a stimulus signal through the target via one or more electrodes. The CEW includes a propulsion system. The propulsion system provides a force that launches the one or more electrodes toward the target to deliver the stimulus signal. The propulsion system includes a canister of pressurized gas, an anvil, and a manifold. The canister releases the pressurized gas. The manifold delivers the pressurized gas to the electrodes to launch the electrodes. The canister has a cavity and an opening. A lid seals the opening to retain the pressurized gas in the cavity of the canister. The lid includes notches to fill the cavity with the pressurized gas.

Abstract: The invention relates to a security device forming a pressurized gas release valve, said device including a body that defines a gas flow channel extending between a first upstream end, to be placed in contact with a source of pressurized gas, and a second downstream end, to be placed in contact with the outer atmosphere, the device including a stopper that is located on the channel so as to prevent the flow of the gas between the upstream end and the downstream end in a normal situation, the stopper being fusible and/or frangible so as to release the gas passage in the event of a dangerous situation when a pressure and/or a temperature exceeds a predetermined threshold. Said device is characterized in that said device includes a tank of an unstable, exothermically decomposable gas that is placed in communication with the pressurized gas released during the melting/breaking of the stopper.

Abstract: A connector for a container, particularly a cask, comprises a bush (14), intended to be received in an opening (11) in the container through which liquid is discharged, in use. The bush has a closed end (17) with a weakened portion (18), an inner thread (20) and an inner deformable portion (21). Sealing means (23) are intended to be disposed between the exterior of the bush and the interior of the opening at the position of the deformable portion. An insert (15) is screw-threadedly engageable within the bush so as to deform the deformable portion, thereby effecting compression, and thus sealing, of the sealing means between the bush and the container.

Abstract: The present invention provides a method for coating the interior surface of a cylinder with a uniform, relatively thick layer of a polymeric material. The method includes the steps of dispersing a particulate polymeric material into the interior cavity of a cylinder. Any openings in the cylinder are then closed. The cylinder is then subjected to rotational movement while at the same time subjecting the cylinder to oscillation in a vertical plane. The polymeric material is then heated to a temperature above the melting point of the polymeric material, and maintained at that temperature for a time sufficient to coat the polymeric material onto the interior surface of the cylinder. The rotation and oscillation of the cylinder is then halted and the polymeric material is cooled.

Abstract: An air bag system (10) includes an inflator (14) containing ignitable gas generating material (60) which, when ignited, generates gas for inflating the air bag (12). The system (10) further includes a collision sensor (96), a first actuator assembly (64) and a second actuator assembly (62). The collision sensor (96) senses a predetermined amount of vehicle deceleration which is indicative of a collision, and provides a collision signal upon sensing such deceleration. The first actuator assembly (64) ignites the gas generating material (60) in response to the collision signal. The second actuator assembly (62) ignites the gas generating material (60) when the ambient temperature of the inflator (14) reaches a predetermined elevated level. The second actuator assembly (62) includes a bi-metal disk (112) which deflects from a concave shape to a relatively convex shape when the ambient temperature increases to the predetermined elevated level.
