Abstract
Abstract A fill pipe for a subterranean storage tank has a hydraulic jump therein, near the bottom of the pipe and near the bottom of the tank, to absorb a portion of the kinetic energy of the falling liquid. The fill pipe has a smaller pipe therein, to enable removal of water from the tank floor.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
146 words
In combination with a subterranean storage tank for liquid fuel: a continuous fill pipe extending substantially vertically from the surface to the top of said tank and thence substantially vertically through the interior of said tank to the bottom thereof, said pipe being coupled to said tank interior near the bottom thereof, the liquid flowing downwardly through said pipe during a tank-filling operation developing a substantial amount of kinetic energy; means cooperating with said pipe for absorbing an appreciable portion of the kinetic energy of said liquid prior to the termination of flow of the liquid from said pipe through said coupling into said tank interior; and a substantially vertical tube, whose diameter is less than that of said pipe, mounted within said pipe, the lower end of said tube opening closely adjacent the bottom of said tank and said tube extending upwardly to the surface.
Claim 2
Dependent Claim
146 words
In combination with a subterranean storage tank for liquid fuel: a continuous fill pipe extending substantially vertically from the surface to the top of said tank and thence substantially vertically through the interior of said tank to the bottom thereof, said pipe being coupled to said tank interior near the bottom thereof, the liquid flowing downwardly through said pipe during a tank-filling operation developing a substantial amount of kinetic energy; means cooperating with said pipe for absorbing an appreciable portion of the kinetic energy of said liquid prior to the termination of flow of the liquid from said pipe through said coupling into said tank interior; and a substantially vertical tube, whose diameter is less than that of said pipe, mounted within said pipe, the lower end of said tube opening closely adjacent the bottom of said tank and said tube extending upwardly to the surface.
Claim 3
Dependent Claim
50 words
Combination of claim 1, including also a hollow, frustoconical member having its upper, small-diameter end connected for fluid transmission to the lower end of said tube; the lower end of said full pipe being sealed to the outer surface of said member at the lower, large-diameter end of the latter.
Claim 4
Dependent Claim
14 words
Combination defined in claim 1, wherein said tube is mounted concentrically in said pipe.
Claim 5
Dependent Claim
22 words
Combination defined in claim 1, wherein the lower end of said tube is fastened to the lower end of said fill pipe.
