  • Apparatus for charging canisters with a high pressure gas
    Patent number: 6212854
    Abstract: An apparatus 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 including means having a guide passageway therethrough, engageable with the canister in sealing engagement with the guide passageway communicating with the filler opening of the canister, means for conveying a gas under pressure to the guide passageway of the sealing means when the sealing means is disposed in sealing engagement with the canister, rotary means for dispensing a welding ball for delivery through the sealing means to be deposited on the canister across the filler opening therein and means for fusing the welding ball when positioned on the canister to close the filler opening in the canister.

  • System and method for charging canisters with a high pressure gas
    Patent number: 5791122
    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 membe
