Abstract
Abstract Pressure containment vessel apparatus includes a cylinder which receives a leaking gas cylinder and which includes an outwardly extending flange for receiving a dome. The dome includes a valve for venting the gas which leaks out of the leaking interior gas cylinder and locking elements which mate with fasteners on the outwardly extending flange to secure the top dome onto the cylinder.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
164 words
Apparatus for containing a leaking pressurized cylinder, comprising, in combination: cylinder means for receiving the leaking gas cylinder, including an outwardly extending first flange, a plurality of spaced apart ears on the first flange, a threaded stud on each ear, and a nut on each threaded stud; and cap means defining a closure for the cylinder means and adapted to be secured to the first flange of the cylinder means, including a dome, a second flange secured to the dome and adapted to be disposed on the first flange, a plurality of arms adapted to be disposed on and secured to the ears of the first flange by the studs and nuts, and a plurality of recesses adapted to allow the cap means to clear the nuts on the studs upon the loosening of the nuts from the arms and the rotating of the cap means to align the recesses with the studs and nuts to remove the cap means from the cylinder means.
Claim 2
Dependent Claim
164 words
Apparatus for containing a leaking pressurized cylinder, comprising, in combination: cylinder means for receiving the leaking gas cylinder, including an outwardly extending first flange, a plurality of spaced apart ears on the first flange, a threaded stud on each ear, and a nut on each threaded stud; and cap means defining a closure for the cylinder means and adapted to be secured to the first flange of the cylinder means, including a dome, a second flange secured to the dome and adapted to be disposed on the first flange, a plurality of arms adapted to be disposed on and secured to the ears of the first flange by the studs and nuts, and a plurality of recesses adapted to allow the cap means to clear the nuts on the studs upon the loosening of the nuts from the arms and the rotating of the cap means to align the recesses with the studs and nuts to remove the cap means from the cylinder means.
Claim 3
Dependent Claim
45 words
The apparatus of claim 1 in which the cap means further includes valve means for venting gas leaking from the gas cylinder disposed within the apparatus and for providing atmospheric pressure within the apparatus in order to remove the cap means from the cylinder means.
Claim 4
Dependent Claim
