Patent ID: 8408836

Claim:
A clamp for joining a first shell and a second shell, the clamp comprising: (1) a bulkhead, wherein the bulkhead is separable coupleable to each of the first shell and second shell; and (2) a wedge, the wedge being mechanically coupleable with the bulkhead with a first separation having a magnitude that is controllable, the wedge comprising: (a) a first ramp dimensioned and arranged to engage a first ridge, the first ridge projecting from the inner surface of the first shell; and (b) a second ramp dimensioned and arranged to engage a second ridge, the second ridge projecting from the inner surface of the second shell; wherein the first ramp imparts a first force on the first shell when the first ramp and first ridge are engaged, the first force being directed toward the second shell, and wherein the magnitude of the first force is based on the first separation; and wherein the second ramp imparts a second force on the second shell when the second ramp and the second ridge are engaged, the second force being directed toward the first shell, and wherein the magnitude of the second force is based on the magnitude of the first separation.
