Abstract: A gas generator includes a housing main body made of metal, a holder assembly, and an igniter. The holder assembly includes a holder portion made of metal and a connector portion made of resin. The holder portion includes a first barrel portion and an annular projection. The connector portion includes a second barrel portion and a cylindrical portion. The cylindrical portion is inserted in the housing main body and externally attached to the first barrel portion. As a portion of the housing main body corresponding to the cylindrical portion is decreased in diameter, the cylindrical portion is compressed by being sandwiched between the portion of the housing main body decreased in diameter and the first barrel portion so as to seal a gap between the housing main body and the first barrel portion.

Abstract: A device is disclosed for controlling a rate of gas pressure increase generated by a propellant for propelling a projectile from an upstream towards a downstream end of a gun barrel. The device includes a first surface area defined by the propellant and a deterrent applied to a second surface area defined by the first surface area, the second surface area being less than the first surface area. The arrangement is such that the second surface area defines a deterrent free third surface area of the propellant. A primer is operatively disposed relative to the third surface area such that when the primer is activated, the third surface area of the propellant is ignited. The arrangement is such that firstly, while the third surface area is burning and generating gas between the upstream end of the gun barrel and the projectile, the rate of gas pressure increase begins to propel the projectile towards the downstream end of the gun barrel. Secondly, the third surface area of the propellant while burning exposes a progressively increasing surface area of the propellant for burning together with an associated increased generation of gas, the increasing surface area of the propellant defining a concave crater, the crater having a wall which progressively increases in surface area during the burning such that the rate of increase in gas pressure continues to increase for accelerating the projectile towards the downstream end of the gun barrel.

Abstract: A method of forming composite materials includes mixing a first metal precursor with a chelating agent to form a first metal-chelate complex. The first metal-chelate complex is added to a polymer binder having terminating hydroxyl groups to form a polymer binder-first metal-chelate. The polymer binder first metal-chelate complex is mixed with an aluminum precursor. The aluminum precursor decomposes forming aluminum nanoparticles dispersed in a continuous phase material having metallic aluminum cores. At least one of the first metal-chelate complex and the first metal is dissolved in the continuous phase. The aluminum nanoparticles can have a passivating coating layer thereon provided by the polymer binder, or can have a passivating coating layer formed by including an epoxide, alcohol, carboxylic acid, or amine in the adding that forms passivating compound(s) which add further protection that can provide complete protection from oxidation of the metallic aluminum cores by air.
