In regards to claim 1, in Figures 4-5 and paragraphs detailing said figures, Akhund discloses a closure for pipelines carrying a fluid under pressure, the closure comprising a door (12), a barrel collar having a horizontal sealing face (near 40) and a vertical sealing face (50) relative to the door; and at least one clamp ring (14) adapted to capture a circumferential portion of the door and the barrel collar when in a clamped state; the closure further comprising: one or more seals located on the vertical sealing face, the one or more seals (46) being circumferential and arranged to alter a path of a leak pathway between the horizontal sealing face of the barrel collar and an ambient environment outside of the door connected to the barrel collar and to cause a pressure drop across the one or more seals.
In regards to claim 2, in Figures 4-5 and paragraphs detailing said figures, Akhund discloses the horizontal sealing face of the barrel collar including (in contact with) a primary seal (40) adapted to seal the door against the barrel collar.
In regards to claim 3, in Figures 4-5 and paragraphs detailing said figures, Akhund discloses the primary seal and the one or more seals are arranged coaxial with the barrel collar.
In regards to claim 4, in Figures 4-5 and paragraphs detailing said figures, Akhund discloses the one or more seals has a higher durometer than that of the primary seal ([0019]).
In regards to claim 5, in Figures 4-5 and paragraphs detailing said figures, Akhund discloses the one or more seals has a smaller cross-sectional diameter than the primary seal.
In regards to claim 6, in Figures 4-5 and paragraphs detailing said figures, Akhund discloses the primary seal lies in a different plane than the one or more seals.
In regards to claim 8, in Figures 4-5 and paragraphs detailing said figures, Akhund discloses a groove in either the barrel collar or the door adapted to receive a corresponding seal of the one or more seals.

In regards to claim 15, in Figures 4-5 and paragraphs [0018]-[0020], Akhund discloses the closure includes a primary seal on a horizontal sealing face of the barrel collar.
