| 102531000 | For gas-powered tools or means | 9 |
| 20080236436 | Pyrotechnic drive unit and method for the production of such a unit - A pyrotechnic drive unit includes a cylinder tube ( | 10-02-2008 |
| 20090301339 | Actuator with actuating pin - An actuator includes a piston having an actuating pin, a squib, and a cylinder case. The cylinder case has a peripheral wall part that covers the circumference of the piston and a ceiling wall part having a through hole which allows an actuating pin to protrude from the through hole. The actuator is configured to make the a piston move backward along with the actuating pin by ejecting a driving gas generated from the squib to a space between the ceiling wall part and the piston during actuation. A sealing ring which is relatively movable with respect to the actuating pin while maintaining the state of sealing up a gap between the actuating pin and the through hole, is provided at an inner face side of the ceiling wall part. | 12-10-2009 |
| 20110132223 | Non-explosive power source for actuating a subsurface tool - A power source for actuating a subsurface tool is described herein, the power source comprising thermite in a quantity sufficient to generate a thermite reaction, and a polymer disposed in association with the thermite. The polymer produces a gas when the thermite reaction occurs, the gas slowing the thermite reaction. The slowed thermite reaction enables a continuous pressure to be provided to the subsurface tool over a period of time, providing superior actuation over a conventional explosive power charge, through a non-explosive reaction. | 06-09-2011 |
| 20110253000 | GAS GENERATOR FOR RESTRAINING DEVICE OF VEHICLE - The present invention provides a filterless gas generator, including a housing having a closure shell, a diffuser and a flange portion, an inner tube member accommodating an igniter coaxially with the central axis of the housing, an opening end of the inner tube member located in a bottom plate of the closure shell and a ventilating portion formed at the opening end, | 10-20-2011 |
| 20120060717 | GAS CARTRIDGE - A method of forming an inner can of a gas cartridge including securing inner can material and pre-stressing the material such that flexion thereof during gas cartridge use is distributed. | 03-15-2012 |
| 20120216701 | Non-explosive power source for actuating a subsurface tool - A power source for applying a force to an object includes thermite in a quantity sufficient to generate a thermite reaction, and a gas producing substance disposed in association with the thermite. The gas producing substance produces a gas when the thermite reaction. The thermite reaction, the gas, or combinations thereof provide a force to the object. | 08-30-2012 |
| 20130220161 | Pyrotechnic Pressure Accumulator - A pyrotechnic pressure accumulator includes an elongated body extending from a first end of a pyrotechnic section to a discharge end of a hydraulic section. A propellant charge located in a gas chamber of the pyrotechnic section, a piston movably disposed the hydraulic section, and a fluid disposed in a hydraulic chamber between the piston and the discharge end, wherein the fluid is exhausted under pressure through a discharge port in response to ignition of the propellant charge. | 08-29-2013 |
| 20130233197 | GAS GENERATOR FOR RESTRAINING DEVICE - A gas generator for a restraining device includes, a housing having an ignition device and a diffuser portion, and a gas generating agent charged in an inner space of the housing, a partition member having a communication hole and being disposed to incline regarding a long axis of the housing, thereby dividing the inner space into a gas generating agent charging space and a gas flow channel space, the gas flow channel space communicating with the diffuser portion, both of the edges of the partition member being abutted against an inner circumferential surface of the housing, a cross-sectional area of the gas generating agent charging space decreasing from the ignition device side at one end of the housing to the diffuser portion side at the other end of the housing, a cross-sectional area of the gas flow channel space increasing from the ignition device side to the diffuser portion side. | 09-12-2013 |
| 20140137761 | NON-EXPLOSIVE POWER SOURCE FOR ACTUATING A SUBSURFACE TOOL - Power sources and methods for applying a force to an object include use of thermite in a quantity sufficient to generate a thermite reaction, and a gas producing substance disposed in association with the thermite. The gas producing substance produces a gas when the thermite reaction occurs. The thermite reaction, the gas, or combinations thereof provide a force to the object. The gas can slow the thermite reaction to enable slower or continuous application of force while being non-extinguishing of the thermite reaction. The gas can further control heat transfer from the thermite reaction to adjacent objects. | 05-22-2014 |
