Abstract
Abstract A portable pressure bin defined by a tubular tank terminating in upper and lower heads and having an access and a drainage opening respectively. A support structure depends from the tank adjacent the drainage opening and supports the tank in an upright position. A tubular skirt extends upwardly of the tank adjacent the head with the access opening and includes apertures for engaging the bin with hoisting means such as hooks or cables. A ring-shaped stiffener with a U-shaped cross section is secured to the free end of the skirt portion to impart rigidity thereto and prevent its deflection or crushing while the bin is suspended by the hoisting means. Means for closing the apertures in the heads, for limiting the maximum pressure inside the tank, and for determining the quantity of fluid in the tank are further provided.

Claim 1
Independent Claim
322 words
A bin for holding evaporating fluids during storage and shipment comprising: a. a tank section having a generally cylindrical cross section, said section fabricated of sheet material having relatively low thickness and weight; b. upper and lower head closures sealably secured to each end of said tank section, said closures fabricated of a relatively low strength sheet material and shaped to overlay the ends of said tank section, said lower head closure being provided with a drain opening and closure assembly and said upper closure having an access opening and closure assembly; c. first and second skirt portions affixed to said head closures to form an extension therefrom circumjacent, respectively, to said upper and lower head closures, said second skirt portion formed to extend longitudinally away from said lower head closure forming a support surface for transmitting forces imposed therethrough during usage of said bin in a generally uniform distribution of shear stresses between said lower skirt portion and said bin, and further said second skirt portion shielding the drain opening and closure assembly affixed to said lower head portion; d. at least two hollow support members secured to the support surface of said second skirt portion, said support members oriented transverse to said tank section and second skirt portion to provide a ground engagement surface when said tank is in the upright position and to engage said first skirt portion when one bin is stacked vertically upon another; and e. means forming a plurality of openings in said first skirt portion, said openings designed to engage tank-hoisting means for lifting and suspending said bin, said first skirt portion formed to extend longitudinally away from said upper head closure so as to provide a lead transmitting member for causing the forces imposed therethrough by lifting and suspending of said bin by said last means to be transmitted as generally uniformly distributed shear stresses between said first skirt portion and said tank section.
Claim 2
Dependent Claim
322 words
A bin for holding evaporating fluids during storage and shipment comprising: a. a tank section having a generally cylindrical cross section, said section fabricated of sheet material having relatively low thickness and weight; b. upper and lower head closures sealably secured to each end of said tank section, said closures fabricated of a relatively low strength sheet material and shaped to overlay the ends of said tank section, said lower head closure being provided with a drain opening and closure assembly and said upper closure having an access opening and closure assembly; c. first and second skirt portions affixed to said head closures to form an extension therefrom circumjacent, respectively, to said upper and lower head closures, said second skirt portion formed to extend longitudinally away from said lower head closure forming a support surface for transmitting forces imposed therethrough during usage of said bin in a generally uniform distribution of shear stresses between said lower skirt portion and said bin, and further said second skirt portion shielding the drain opening and closure assembly affixed to said lower head portion; d. at least two hollow support members secured to the support surface of said second skirt portion, said support members oriented transverse to said tank section and second skirt portion to provide a ground engagement surface when said tank is in the upright position and to engage said first skirt portion when one bin is stacked vertically upon another; and e. means forming a plurality of openings in said first skirt portion, said openings designed to engage tank-hoisting means for lifting and suspending said bin, said first skirt portion formed to extend longitudinally away from said upper head closure so as to provide a lead transmitting member for causing the forces imposed therethrough by lifting and suspending of said bin by said last means to be transmitted as generally uniformly distributed shear stresses between said first skirt portion and said tank section.
Claim 3
Dependent Claim
56 words
A bin in accordance with claim 1 and stiffening means of relatively high strength secured circumjacent to the free end of said first and second skirt portions to reinforce said portions, respectively, against deformation caused by said tank-hoisting means when the tank is suspended therefrom, and against deformation caused by ground engagement of said support members.
Claim 4
Dependent Claim
21 words
Apparatus according to claim 1 including means connected with said first skirt portion for mounting an agitator adjacent the access opening.
Claim 5
Dependent Claim
27 words
Apparatus according to claim 2 wherein said stiffeners have a U-shaped cross section and are bolted respectively to each of tHe interior sides of said skirt portions.
Claim 6
Dependent Claim
26 words
Apparatus according to claim 1 including mounting holes in said first skirt portion for demountably securing an agitator support to the portion adjacent the access opening.
Claim 7
Dependent Claim
89 words
Apparatus according to claim 1, wherein said support member includes pedestals supporting the bin, a portion of the pedestals closest to an axis of the tank being spaced from the axis a distance slightly greater than the radius of the skirt portion, whereby two or more bins stacked on top of each other are prevented from moving relative to each other in a direction transverse to the axis of the tank by the interengagement between the pedestals of the upper bin and the skirt portion of the lower bin.
Claim 8
Dependent Claim
30 words
Apparatus according to claim 1 including holes in a portion of the stiffener which is transverse to said first skirt for mounting an agitator support member adjacent the access opening.
Claim 9
Dependent Claim
21 words
Apparatus according to claim 1 wherein the tank and skirts are constructed of aluminum and the stiffener is constructed of steel.
