ABSTRACT:
A system for charging a metallic canister having a filler opening therein with a gas under pressure and then sealing the opening to provide a closed, pressurized canister generally consisting of means for retaining the canister in a predetermined orientation, a sealing member having a guide passageway therein displaceable between an extended position in sealing engagement with a canister disposed in the predetermined orientation, with the guide passageway therein communicating with the filler opening of the canister, and a retracted position out of sealing engagement with the canister, a first means for applying a gas under pressure to a first side of the sealing member to urge the sealing member into into its retracted position, second means for supplying a gas under pressure to an opposite side of the sealing member to urge the sealing member into its extended position in sealing engagement with the canister, third means for supplying a gas under a third pressure to the guide passageway of the sealing member when the sealing member is in its extended position to pressurize the canister, means for welding the filler opening of the canister closed when the sealing member is in its extended position in sealing engagement with the canister and while operating the third gas supplying means and maintaining the pressure in the canister at the third pressure, and means for sequentially deactivating the third gas supplying means, deactivating the second gas supplying means and activating the first gas supplying means to return the sealing member to its retracted position.
