the semicircular first yoke member includes a first threaded end and a second threaded end,
the semicircular second yoke member includes a first threaded end and a second threaded end, and
the second automatic system includes:
a first threaded rod configured to engage the first threaded ends of the first yoke member and the second yoke member;
a second threaded rod configured to engage the second threaded ends of the first yoke member and the second yoke member;
a rotation apparatus to rotate one of the first threaded rod and the second threaded rod; and
a connecting apparatus for interconnecting the first threaded rod and the second threaded rod, where rotation of the one of the first threaded rod and the second threaded rod causes rotation of the other of the first threaded rod and the second threaded rod.
12. The blast containment vessel according to claim 1 , further including:
a first manual system configured to manually move the external door into and out of the closed position; and
a second manual system configured to manually move the yoke when the external door is in the closed position.
13. The blast containment vessel according to claim 1 wherein the vessel is adapted for containing a blast of up to and including 26 lbs. of TNT.
14. A blast containment vessel, comprising:
a body having an opening;
a door configured to form a seal surrounding the opening when the door is in a closed position;
a series of o-rings positioned to seal a joint between the external door and the opening when the external door is in the closed position and wherein the external door includes a door support ring surrounding a perimeter of the external door and the body includes an outwardly extending ring surrounding the opening for supporting the door support ring;
a ridge located on the door support ring;
a valley located in the outwardly extending ring, said valley configured to receive the ridge and wherein at least one of said o-rings is positioned in the valley to form a first seal between the body and the external door when the external door is in the closed position;
