  • Patent number: 7544111
    Abstract: The present invention relates to a gas management device 10; 20; 30; 40; 50 comprising: a gas inlet 11; 32; 42; 52 adapted to secure a casing of a vessel 22, preferably a closure 26 sealing an opening of a gas cylinder containing pressurized gas; a gas outlet 12; 33; 43; 53 adapted to be secured to an inflatable unit 23; and a puncture device 10b; 31b; 41b; 51b for puncturing the casing of the vessel 22. The puncture device 10b; 31b; 41b; 51b comprises a pyrotechnical detonator 16 that, when activated, creates a chock wave which punctures the casing of the vessel 22, whereby gas from the vessel 22 is directed to the inflatable unit 23. The invention also relates to a method and a system for transferring gas from a pressurized vessel to an inflatable unit via a gas management device.

  • Publication number: 20090064918
    Abstract: The invention relates to an arrangement (206) for manually releasing nautical life saving equipment, e.g. containers for inflatable life rafts. The release arrangement (206) is located as a connecting link between a first rope arrangement (205) and a second rope arrangement (215) adapted to fixating the life saving equipment. The second rope arrangement (215) forms a loop (213) encircling the first rope arrangement (205). The first rope arrangement (205) is fixed to a connecting stick (207) so that the connecting stick (207) together with the first rope arrangement (205) forms a stop preventing the loop (213) of the second rope arrangement (215) to run along the first rope arrangement (205). The connecting stick (207) is adapted, at release, to turn around an axis formed by the loop (213) of the second rope arrangement (215). The axis is orthogonal to the longitudinal axis of the rope arrangements.

  • Patent number: 7302739
    Abstract: A device is for fastening emergency equipment to a ship's deck or to a structure on a ship's deck. The device includes a first and a second fastening facility for, respectively, a first external and a second external fastening device having, respectively, a first and a second tensile strength. The device further includes a third fastening facility for a third external fastening device having a third tensile strength. When the device is in operation, the second and the third fastening facility are mutually connected both by a connecting device incorporated in the device and by the first external fastening device. The connecting device incorporated in the device absorbs load between the second and the third fastening facility if the first external fastening device stops working.
