<p>The apparatus (1) includes an aluminium backing plate (2) onto which a sponge rubber layer (3) is bonded. The sponge rubber layer (3) has an impervious skin (4) which is impervious to the liquids contained in a transport tanker or tank (not illustrated) to which the apparatus is to be applied for sealing a rupture therein. Naturally, the type of impervious skin (4) is selected to be appropriate for the type of liquid which is either stored or transported in the tank. At the periphery of the backing plate (2) are a set of eight permanent magnets (5) which are also bonded to the aluminium plate (2). When a rupture occurs in a tank or transport tanker made of steel or another ferrous material the apparatus (1) is used to stem the flow of the leak by fastening the magnets to the tank to thereby compress the sponge rubber layer against the rupture.</p> |
