  • Patent number: 7222561
    Abstract: A pyromechanical cutting element has a housing (2) in which an electrical conductor (3) is arranged, a cutting plunger (5) with a cutting tool (8) to cut through the electrical conductor (3), and pyrotechnic charge (13) to drive the cutting plunger (5), with the cutting tool (8) bending over the electrical conductor (3) after cutting through it and forming a bending tongue (18) that sticks out from the conductor (3) in a way that interrupts the conductor (3). The electrical conductor (3) has a cross-sectional area reduction in the longitudinal direction (4) consisting of two transverse sides and two longitudinal sides.

  • Patent number: 7134445
    Abstract: The invention concerns the technical field of micro-actuators used for mechanical, chemical, electrical or thermal functions in microsystems, for microelectronic applications such as chips, or biomedical functions such as microfluidics integrating cards. The invention concerns a micro-actuator comprising a so-called main chamber, made in a solid support and containing a so-called main pyrotechnic charge, the main chamber being sealed and delimited by solid support walls and by a deformable membrane, such that the gases emitted by the combustion of the main pyrotechnic charge, enable the volume of the chamber to be increased by deforming the membrane while maintaining intact the solid walls of the main chamber. The invention is characterized in that it comprises means for evacuating the gases from the main chamber.

  • Patent number: 5005725
    Abstract: A cover release mechanism to enable a cover to be released while being subjected to a high inwardly acting pressure differential. The mechanism comprises:a caliper mechanism having two or more claiper members mounted within the cover, at least one of which members has an associated sealing member; anda high energy release mechanism mounted within the cover so that it acts in association with the caliper mechanism.Under normal operating conditions, with the cover member secured into position, the or each of the sealing members engages in a detent, normally a throughbore, in the cover. In order to release the cover, the high energy release mechanism is activated causing at least one of the caliper members to move, and the associated sealing means to disengage from the respective detents.

  • Patent number: 4970936
    Abstract: A container of a pressurized gas has an elongated inlet/outlet tubular neck which extends into a housing passage. A cap sealed over the inlet/outlet neck has a platelike member connected to the neck via a hollow support or column. A piston is slidingly received within the housing passage for movement toward the platelike member and has a rod which can be brought into contact with the member eccentrically of the hollow support. A squib on being discharged driving the piston toward the platelike member and rod cantilevers about the hollow support causing it to break and release the gas for use.

  • Patent number: 4530269
    Abstract: The present disclosure describes a latch assembly wherein structural members are coupled to each other by an electric match-type device interposed therebetween. The latter device generally comprises a body portion having electrical connections thereto and a rigid mass of combustible material firmly adhered to an extremity thereof. At least a pair of the structural members are individually coupled to the combustible material. Remote activation of the match by the passage of electric current therethrough results in the firing of the combustible material and the consequent opening of the latch through the elimination of the coupling force between the structural members.

  • Patent number: 4424914
    Abstract: A completely separable seal for a container opening having a throat with a restriction therein including a casing, an explosive charge in the casing, a projectile tethered to the casing, the projectile including a thin completely separable peripheral diaphragm for closing the container throat having upper and lower surfaces, the charge mounted against the upper surface, means on the seal for engaging the throat restriction when the charge has been fired to subsequently limit downward thrust of the projectile into the container after separation of the diaphragm from the container throat to thus permit the projectile to reverse direction as the upward explosive forces overcome the downward explosive forces to thus propel the casing and tethered projectile from the container throat thus opening the container. The invention includes the complete closure for the container as well as the method of opening the rupturable sealed aperture.

  • Patent number: 4248257
    Abstract: A gas actuated valve enabling high-speed actuation silently and rapidly os one or more blocked ports in a floodable container, thereby permitting the flooding of the otherwise closed container by ambient fluid. The valve includes a sleeve mounted for sliding movement about a base, the latter being attached to the interior of the container at each port. An electrically-initiated, gas-generating pyrotechnic bolt is threadedly connected between, and disposed in a cavity defined between the sleeve and the base. The bolt, before actuation, functions as a tensile member to withstand ambient pressure, thereby preventing the valve from opening prematurely. When actuated, the bolt fuses, separates, and releases hot gases into the cavity which expand and bear against the sleeve, causing the sleeve to move away from the port so that the container port opens completely thereby flooding the container.

  • Patent number: 4126184
    Abstract: An instantaneously actuatable, field-serviceable valve unit for pressurized fire suppression systems which allows extremely fast, essentially uninterrupted flow of extinguishant upon operation thereof and is constructed for permitting easy recharging and periodic servicing of the system in the field. The unit includes an elongated flow tube connected to a supply of extinguishant and having a pair of removably mounted rupture discs respectively located across the end of the tube and received in an aperture through the sidewall thereof, so that both discs experience the pressure of the extinguishant; a detonator is removably installed outside of the tube adjacent the sidewall-mounted disc for ready replacement thereof in the field, and is electrically actuatable in response to combustion conditions to explode and create a pressure sufficient to instantaneously burst the discs so that the pressurized extinguishant is released and allowed to flow uninterruptedly for quickly suppressing a fire.

  • Patent number: 4077423
    Abstract: A high pressure gas container hermetically confining therein a high pressure gas for inflating instantaneously a safety air bag to protect occupants in a vehicle is provided with an improved discharge valve for blowing out the gas from the container. The discharge valve comprises a sealing disk disposed at a blocking cock portion, which disk has a thick center portion and thin peripheral portion so that the whole disk may be utterly ruptured upon explosion of a detonator disposed adjacent to the thicker portion of the sealing disk. Such complete destruction of the sealing disk will result in a formation of a large opening for blowing out the high pressure gas and hence allows a rapid inflation of the safety air bag due to increased flow rate of the jetted high pressure gas from the container.

  • Patent number: 4046156
    Abstract: Valve apparatus is disclosed for discharging pressurized fire extinguisher fluid from a container. The valve includes a diaphragm which is removably mounted within a two-part housing to facilitate field replacement. The diaphragm is formed with a semi-spherical shell which is mounted across a passage in the housing with a concave side of the shell facing the pressurized fluid. The shell is fabricated of a metal which is pre-stressed so that the diaphragm ruptures above a predetermined fluid pressure for relieving over-pressure from the container. An annular rim of the diaphragm includes a ductile metal ring which is compressed between the housing parts into fluid sealing relationship with an annular knife edge seal. A squib cartridge is mounted in the housing to rupture the diaphragm and permit the fluid to discharge through the passage. A screen is mounted in the passage to screen out fragments of the ruptured diaphragm from the flow stream.
