Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
68 words
A pressure-retentive vessel comprising a sealed lining defining a pressure-retaining chamber, and a concrete body around said lining, said lining comprising an outer shell anchored to said body and an inner liner spaced from said outer shell and formed with a corrosion-resistant corrugated inner wall having crests alternating with troughs, and means for supporting the crests of the corrugated inner wall in force-transmitting relationship with said outer shell.
Claim 2
Dependent Claim
68 words
A pressure-retentive vessel comprising a sealed lining defining a pressure-retaining chamber, and a concrete body around said lining, said lining comprising an outer shell anchored to said body and an inner liner spaced from said outer shell and formed with a corrosion-resistant corrugated inner wall having crests alternating with troughs, and means for supporting the crests of the corrugated inner wall in force-transmitting relationship with said outer shell.
Claim 3
Dependent Claim
52 words
The pressure-retentive vessel defined in claim 1 wherein said inner liner further comprises a substantially cylindrical outer wall coaxial with said outer shell and defining a compartment therewith, said means for supporting said crests including a profile member bearing upon said outer wall and received within each crest of said inner wall.
Claim 4
Dependent Claim
38 words
The pressure-retentive vessel defined in claim 2 wherein each of said profile members has a portion complementarily received in the underside of the respective crest and a pair of struts extending radially into engagement with said outer wall.
Claim 5
Dependent Claim
32 words
The pressure-retentive vessel defined in claim 3 wherein said profile members are formed as channels of U-section with the arms of the U being welded to the interior of said outer wall.
Claim 6
Dependent Claim
26 words
The pressure-retentive vessel defined in claim 4, further comprising a multiplicity of spaced-apart spokes traversing said compartment and anchoring said outer wall to said outer shell.
Claim 7
Dependent Claim
16 words
The pressure-retentive vessel defined in claim 5 wherein said compartment is filled with force-transmitting thermal insulation.
Claim 8
Dependent Claim
24 words
The pressure-retentive vessel defined in claim 6 wherein said spokes extend through said outer shell and are anchored in the concrete of said body.
Claim 9
Dependent Claim
22 words
The pressure-retentive vessel defined in claim 7 wherein said chamber has an upright axis and the corrugations extend parallel to said axis.
Claim 10
Dependent Claim
25 words
The pressure-retentive vessel defined in claim 7 wherein said chamber has a vertical axis and said corrugations lie in horizontal planes perpendicular to said axis.
