| 1432851 Gas-generating charges NISSAN MOTOR CO Ltd 21 Sept 1973 [28 Sept 1972] 44473/73 Heading F3A A charge for supplying pressurized gas to an inflatable bag safety system in a vehicle, comprises a layer 14 of combustible, gasproducing material supported on a solid or hollow core 12. The core may be made of thermoplastic resin, ceramics, potassium perchlorate or ebonite and should be strong enough to resist fracture if exposed to vibrations, a collision of the vehicle, or combustion of the layer 14. Alternatively the core may be made of thermoplastics material which shatters in response to combustion of the layer 14. The core may otherwise melt upon combustion of the layer 14 to produce an alkali gas which neutralizes any acidic gas produced by combustion of the layer 14. | ||||||

| 1388697 Generating combustion products under pressure SOC NATIONALE DES POUDRES ET EXPLOSIFS 31 Oct 1972 [ 8 Nov 1971] 50138/72 Heading F1L A combustion gas generator comprises a cylindrical casing divided by a transverse partition 26 into a combustion chamber 6 containing a solid propellant and a second chamber 9 containing a solid coolant 29, there being means to direct the combustion gases into chamber 9 and prevent them from flowing directly there-through. The generator may be used for inflating lifeboats or sledges or for fire extinguishing. In the arrangement shown partition 26 has peripheral gas flow ports 27 and direct flow through coolant chamber 9 is prevented by a helical screw 28. The cooled gases leave chamber 9 through a filter grid and outlet nozzle 4. In a modification, Fig.3 (not shown), the helical screw (22) tapers towards the outlet nozzle and ports 26 are replaced by two oblique orifices (24) directed in the same sense as the helix and covered by diaphragms (17) which rupture at the moment of ignition. In another arrangement, Fig.6 (not shown), the dividing partition (30) has a central nozzle 31 which directs the combustion gases into a chamber (32) containing a deflector (33) integral with a grid (34) which retains the coolant, the grid being divided into compartments by a bundle of metal tubes (35). The coolant consists of granules of hydrated or anhydrous salts which can be decomposed by heat, e.g. ammonium carbonate, bicarbonate, carbamate, chloride, acetate or oxalate, calcium oxalate, guanidine oxalate or nitrate, aminoguanidine nitrate, or urea. The solid propellant may be slow burning having a potential of 483 cal/gm. | ||||||

| A pyrotechnic actuator mechanism comprises a cover member which includes a first wall member which is opposed to a release portion of an ignition unit, and a second wall member which is connected thereto and which has a free end portion embedded in a fixing member. When an ignition charge contained in the ignition unit is combusted, then the cover member is moved in the propulsion direction so that a predetermined closed space is expanded in the propulsion direction of a piston, and the movement of the cover member is regulated so that a state, in which the free end portion of the second wall member is embedded in the fixing member, is maintained at a maximum propulsion position of the cover member. Accordingly, the residue, which is produced by the combustion of the ignition charge, is preferably suppressed from being discharged or emitted to the outside. | ||||||

| A gas generator contains an anti-vibration, auto-igniting pad. The pad is formed from a mixture of a known auto-igniting composition mixed with an elastomeric polymer, and then cured, thereby forming a polymer—auto-igniting composition matrix. The pad is placed in thermodynamic communication with a housing on the gas generator, thereby enhancing the safety of the gas generator while yet providing a multi-functional pad. The pad is formulated to reduce vibrations when biased against an associated gas generant, while augmenting the amount of gas produced upon gas generator activation, while yet providing an auto-igniting material that is ignited during a high heat event. | ||||||

The at least one outlet orifice is provided with a seal adapted to pass from a closed state to an open state when the pressure inside the delay chamber reaches a rupture limit pressure. | ||||||

| A high flow rate inflator intended to be threaded into or onto the threaded neck of a conventional gas cylinder. The inflator comprises a spring-loaded ballasted firing pin that is retained in a cocked position by a tethered trigger pin. Upon firing by pulling on the trigger pin, the firing pin forcibly moves into engagement with a power primer mounted with a power primer holder to ignite the same, whereupon the ignition gases forcibly drives a hollow larger diameter pierce pin mounted within an interior cylinder into the frangible seal of the gas cartridge to cut a large-bore hole therethrough and allow gas escaping from the gas cylinder to flow at a high rate through the inflator into an inflatable device. | ||||||
