Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
117 words
A new and improved vessel structure, including: a first vessel section having an annular end portion formed of inner and outer, concentric connector rings separated to form an annular recess; a second vessel section having an annular end portion including a connector ring for insertion into said annular recess of said first vessel section; seal means mounted with said annular end portions of said first and second vessel sections for sealing said first and second vessel sections against the passage of fluid therebetween; and said connector rings receiving a radially directed pin mounted for rotation with respect to said connector rings and including pre-load means for locking said connector rings together and for pre-compressing said seal means.
Claim 2
Dependent Claim
117 words
A new and improved vessel structure, including: a first vessel section having an annular end portion formed of inner and outer, concentric connector rings separated to form an annular recess; a second vessel section having an annular end portion including a connector ring for insertion into said annular recess of said first vessel section; seal means mounted with said annular end portions of said first and second vessel sections for sealing said first and second vessel sections against the passage of fluid therebetween; and said connector rings receiving a radially directed pin mounted for rotation with respect to said connector rings and including pre-load means for locking said connector rings together and for pre-compressing said seal means.
Claim 3
Dependent Claim
90 words
The structure set forth in claim 1, including: said inner and outer connector rings of said first vessel section having radially aligned openings therein for receiving said pin; and said second vessel section connector ring having an opening which is initially out of alignment with said first vessel connector ring openings; and said pin being mounted in said connector ring openings and including eccentric means for moving said second vessel section connector ring opening into closer alignment with said first vessel section connector ring opening for pre-compressing said seal means.
Claim 4
Dependent Claim
54 words
The structure set forth in claim 1, including: a pin mounted with said connector rings for rotation with respect thereto; and said pin including cam means mounted with said second vessel section connector ring for moving said second vessel section from an unlocked to a locked position in which said seal means is pre-compressed.
Claim 5
Dependent Claim
34 words
The structure set forth in claim 3, wherein: said cam means of said pin includes an eccentric portion mounted in said second vessel section connector ring for rotation between an unlocked and locked position.
Claim 6
Dependent Claim
65 words
The structure set forth in claim 2, wherein: said eccentric means includes a portion of said pin which is eccentrically positioned with respect to pin portions mounted in said first vessel section connector ring openings, said eccentric pin portion being mounted in said second vessel section connector ring opening for rotation between locked and unlocked portions, said seal means being pre-compressed in said locked position.
Claim 7
Dependent Claim
107 words
The structure set forth in claim 1, including: said seal means including a seal ring mounted with one of said annular end portions of said first and second vessel sections; said first and second connector rings having a plurality of circumferentially spaced set of openings, wherein each set of openings includes: radially aligned openings in said connector rings of said first vessel section; said second vessel section connector ring having an opening which is initially non-aligned with said first vessel section connector ring openings; and said pin including cam means for moving said first vessel section to a locked position in which said seal ring is pre-compressed.
Claim 8
Dependent Claim
62 words
The structure set forth in claim 1, including: said second vessel section connector ring being seated in said annular groove in a first position in which said seal means is not in compression; and said pre-load means moving said second vessel section connector ring to a second position further seated in said annular groove, in which position said seal means is pre-compressed.
Claim 9
Dependent Claim
58 words
The structure set forth in claim 1, including: said vessel section end portions including opposing annular radial faces, said seal means including an annular seal ring mounted with one of said radial faces; and said pre-load means including means moving said annular seal ring on said one radial face and said other Radial face into initial, pre-compressed engagement.
