Abstract
Abstract A liquid carrying tanker comprising a plurality of closed individual reservoirs for receiving a liquid, an ejecting piping system for connecting the upper part of each reservoir to an empty space, and an impermeable, elastomeric tailored lining releasably fixed to the inner walls of said reservoirs, the said lining being adapted to separate from the walls of at least one of the reservoirs upon a predetermined minimum external concussive pressure and deformation of the walls of said one reservoir, the lining being adapted to stretch upon said pressure and deformation and force the liquid contained therein to flow through said ejecting piping system and towards said empty space.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
173 words
A liquid carrying tanker comprising a plurality of closed individual reservoirs for receiving and carrying a liquid an ejecting piping system connecting the upper part of each reservoir to an empty space and provided with a rapid acting pressure controlled valve adjacent each said reservoirs, said valve keeping the liquid inside the reservoir from flowing into the ejecting piping system during normal operation, and an impermeable, stretchable, elastomeric lining conforming to and extending throughout the entire inner surface of each reservoir and being releasably secured to the inner walls of said reservoirs, the said lining being secured to said walls by releasable means permitting the same to separate from the walls of any one of the reservoirs upon a predetermined minimum external concussive pressure and deformation of the walls of said one reservoir, the lining being stretched upon said pressure and deformation to decrease the volume within said one reservoir and force the liquid contained therein to open said valve and to flow through said ejecting piping system and towards said empty space.
Claim 2
Dependent Claim
173 words
A liquid carrying tanker comprising a plurality of closed individual reservoirs for receiving and carrying a liquid an ejecting piping system connecting the upper part of each reservoir to an empty space and provided with a rapid acting pressure controlled valve adjacent each said reservoirs, said valve keeping the liquid inside the reservoir from flowing into the ejecting piping system during normal operation, and an impermeable, stretchable, elastomeric lining conforming to and extending throughout the entire inner surface of each reservoir and being releasably secured to the inner walls of said reservoirs, the said lining being secured to said walls by releasable means permitting the same to separate from the walls of any one of the reservoirs upon a predetermined minimum external concussive pressure and deformation of the walls of said one reservoir, the lining being stretched upon said pressure and deformation to decrease the volume within said one reservoir and force the liquid contained therein to open said valve and to flow through said ejecting piping system and towards said empty space.
Claim 3
Dependent Claim
51 words
A tanker as recited in claim 1, wherein the said lining is adheringly coated on the walls of each reservoir, the adherence of said lining on the walls of anyone of said reservoirs being adapted to break upon a predetermined minimum pressure and deformation of the walls of said anyone reservoirs.
Claim 4
Dependent Claim
43 words
A tanker as recited in claim 1, wherein the lining comprises three superposed layers, a first layer consisting of a primer having a releasable adhesion, a second layer consisting of an elastomeric high solid and a third layer consisting of a protective coating.
Claim 5
Dependent Claim
37 words
A tanker as recited in claim 3, wherein the primer is made of a compound selected from the group consisting of vinyl chloride/vinyl acetate copolymers, bisphenol A/epichlorhydrin condensates, hexamethylene di-isoyanate/polyester adducts, styrene/butadiene and olefin elastomers, polyvinyl butyral.
Claim 6
Dependent Claim
26 words
A tanker as recited in claim 1, wherein said empty space is a ballast tank, the said ejecting piping system being connected to said ballast tank.
Claim 7
Dependent Claim
30 words
A tAnker as recited in claim 1, comprising a mast pipe reaching substantially above the reservoirs of the tanker, the said mast pipe being connected to the ejecting piping system.
Claim 8
Dependent Claim
41 words
A tanker as recited in claim 1, wherein the lining of each reservoir is made of a plurality of assembled units, sealed together and spaced from the walls of the reservoir and fastening means releasably connecting each unit to said walls.
Claim 9
Dependent Claim
25 words
A tanker as recited in claim 7, wherein the fastening means are mechanical couplings adapted to shear or break away from a predetermined minimum pressure.
