Upon activation and breaking of the fusible element, the penetrator is forced into the gas canister releasing gas to inflate the rescue device. The rescue device is retained within a deployment canister having a cover that is easily sealed and resealed to ease maintenance and operation. The rescue device is incorporated into a remotely activated rescue system including a miniature radio frequency transmitter which may be worn on a user's body such as on a wrist strap.

  • Patent number: 6260570
    Abstract: A raft inflation valve includes a one-piece valve body which is connected to a pressure vessel and which has an inlet communicating with the pressure vessel, a recess for receiving a cartridge having a puncture disc, and a passage which connects the inlet and the recess and which is covered by the puncture disc. The cartridge includes a disc retainer holding the puncture disc in position to block the passage in the valve body, and a bayonet having a cuffing edge which is biased by a spring toward the puncture disc but prohibited from such motion by a ball/link pin held in place by the pull cable ball until the cable is pulled. Once the cable has been pulled to remove the ball, the bayonet is driven by the bias force toward the disc to clearly cut and puncture the disc and permit flow of gas from the pressure vessel through the inlet passage through the disc to the outlet passage in the outlet of the valve.

  • Patent number: 6168487
    Abstract: In inflatable large-size structures such as life boats it is required that an external and easily accessible gas cylinder is hose-connected with a plurality of mutually separated injection areas, because the gas medium, by evaporation and expansion, produces a substantial reduction in temperature at each injection area there will potentially exist choking ice formations. This can be counteracted by distributing the injection over more areas or spots in order to achieve a more rapid and effective transfer of heat from the surroundings for making sure that the inflation can take place in a desirably rapid manner. Conventionally this implies that the structure exhibits exposed connector hoses to the different injection spots, these hoses causing trouble in use of the structure. With the invention it has been recognized that the relevant distribution system may be arranged in the interior of the structure, whereby these troublesome exterior hoses can be entirely avoided.
