Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
90 words
A pressure vessel comprising a first cylindrical vessel portion having at least one open end, a second cylindrical vessel portion engaging said first vessel portion at said open end, a plurality of projections extending from each of said vessel portions, the projecting members of said first vessel portion engaging the projecting members of said second vessel portion to define a plurality of interfaces between the adjacent projecting portions, and at least one smooth surfaced shear pin disposed along each of said interfaces and extending radially with respect to said vessel.
Claim 2
Dependent Claim
90 words
A pressure vessel comprising a first cylindrical vessel portion having at least one open end, a second cylindrical vessel portion engaging said first vessel portion at said open end, a plurality of projections extending from each of said vessel portions, the projecting members of said first vessel portion engaging the projecting members of said second vessel portion to define a plurality of interfaces between the adjacent projecting portions, and at least one smooth surfaced shear pin disposed along each of said interfaces and extending radially with respect to said vessel.
Claim 3
Dependent Claim
24 words
The vessel of claim 1 wherein the projecting members of said first vessel portion mesh with the projecting members of said second vessel portion.
Claim 4
Dependent Claim
