  • Patent number: 4712502
    Abstract: A lipped mouth seal structure with inflated lips mounting a sponge rubber type seal engaging the side of a large container tank or ship such as an oil tanker around an area of puncture or rupture with the lips generally rectangular about an area enclosed thereby. The lips and the area within the lips is spanned by a leak proof flexible membrane overlying the back sides of the lips. The lips underlie, at the top and bottom of the seal structure, transverse cross brace bars retained in rearwardly extended sleeves of the seal structure. The lips are in the form of inflatable rings of rubber (natural rubber, synthetic rubber or rubber-like plastic) mounting the resiliently deflectable sponge rubber type seal on the front ship facing side of lips with the sponge rubber seal along with the inflatable rings resiliently deflectable to conform to ship outer surface irregularities in providing sealed containment about a ship skin rupture opening.

  • Patent number: 4569303
    Abstract: A lipped mouth structure with lips engaging the side of a ship such as an oil tanker around an area of puncture or rupture with a flexible diaper container fastened to the lips and extended outward therefrom. The lip structure has transverse cross brace bars retained in molded pockets of the lip structure with the lips in the form of inflatable rings of rubber (synthetic rubber or rubber like plastic) having a soft pliable surface engaging the side of a ship. Vertically oriented straps with "D" rings at their opposite ends are provided for tying the straps and the lip structure in place on the side of a damaged ship with cables attached to the "D" rings. The flexible diaper container is supported by floats spaced strategically along the length thereof to support the diaper container in its extension along the surface of the water while flexing with wave action of the sea.
