Abstract
A small tank or vessel for the containment of pressurized fluids is formed by joining the outer edges of the arms of integral upright and inverted double-Y sections arranged side by side. The arms are part cylinders terminating in the vertical centerline of a cylinder so that a septum between adjacent cylindrical lobes is formed by the vertical legs of the double-Y. A semi-cylindrical shell may be attached to the outer arms of each outside double-Y form.
Claims10
A fluid tank comprising:
- a first internal septum formed by one unitary pair of upright and inverted Y-shapes with generally vertical legs joined together bottom to bottom, each Y-shape having two laterally extending arcuate arms;
- the arms of said one pair of Y-shapes being internally concave, each part and together forming back to back generally semi-cylinders of a predetermined radius terminating in straight top and bottom outer edges in first and second common vertical planes;
- and
- a side wall comprising a semicylinder of said predetermined radius terminating at top and bottom in straight inner edges in said first common vertical, plane sealed along said inner edges to the outer edges of a top and bottom pair of arms of said first internal septum to form an outer, generally cylindrical lobe therebetween.

A fluid tank comprising:
- a first internal septum formed by one unitary pair of upright and inverted Y-shapes with generally vertical legs joined together bottom to bottom, each Y-shape having two laterally extending arcuate arms;
- the arms of said one pair of Y-shapes on each side of said septum together forming internally concave, generally semi-cylinders of a predetermined radius terminating in straight opposing outer edges along first and second parallel planes, each on a centerline of a cylinder of said predetermined radius;
- and
- a side wall of comprising a semi-cylinder of said predetermined radius terminating at top and bottom in straight inner edges along said first plane, sealed along said inner edges to the outer edges of said first internal septum to form an outer generally cylindrical lobe therebetween.
