20090071320 | SEPARABLE STRUCTURE MATERIAL METHOD - A separable structure includes composite material that is separated or severed by a reactive pyrotechnic material. According to one embodiment, the structure includes a pair of composite laminate structural portions, each including multiple layers of composite material. The portions each extend into an overlap region, within which the composite layers of the two structural portions may be alternately placed, overlapping one another. A reactive material is also placed within this overlap region, for instance being in layers between pairs of the composite material layers. The reactive material may be ignited to cause destruction of the pyrotechnic material, and a matrix or resin material of the composite materials layers in the overlap region. This causes the structure to sever or separate along a line of separation within the overlap region. The separation may occur without need to sever fibers of the composite material. | 03-19-2009 |

The explosive manifold receives the ends of the pressure tube, and includes a detonator for detonating the explosive detonation assembly/cord. The explosive manifold has circular-cross-section fittings for accepting a circular ends of the pressure tube. By not having any part of the pressure tube assembly protrude from the frangible structure, improved performance may be achieved. Having circular fittings also improves the seal between the pressure tube and the explosive manifold. | 04-12-2012 |
20120234162 | PYROTECHNIC ACTUATOR AND METHOD OF ACTUATING A PYROTECHNIC ACTUATOR - A pyrotechnic actuator and a method of actuating the same are described. The actuator comprises a pressure chamber and a piston having such an outer diameter that it is snugly fitted into the pressure chamber. A gas generating ignition and output charge generates gas that pressurizes the pressure chamber and the piston when ignited. The piston is designed such that at least part of its outer diameter expands under the pressure in the pressure chamber such that at least a part of the external piston surface is forced into a press fit against the internal wall of the pressure chamber and therefore seals the pressure chamber. This prevents exhaust gas and flames from escaping from the device in an uncontrolled manner. | 09-20-2012 |

The pyrotechnical actuator is adapted for, upon deployment, moving the sleeve part relative to the nut to a released position forming a release space allowing radial movement of the nut portions. The pyrotechnical actuator is arranged for turning, upon deployment, the sleeve part a predetermined rotational distance to the released position, such that radial movement of the nut portions by formation of the release space is allowed, thereby causing release of a bolt connected to the bolt release arrangement. | 10-22-2015 |
20160001736 | Actuator Housing Sealing Mechanism - A pressurized fluid-powered actuator includes a housing and a striker movably coupled to the housing. Resilient sealing means are positioned between the striker and the housing. The sealing means are compressible so as to seal an end of the housing responsive to a force exerted on the sealing means by the striker in a first direction toward the housing. Releasable retaining means are operatively coupled to the striker and are structured to prevent motion of the striker in a second direction opposite the first direction prior to activation of the actuator, and responsive to a reaction force in the second direction exerted on the striker by the sealing means when the sealing means is compressed. | 01-07-2016 |
