Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
193 words
Pressurizable vessel comprising (a) housing wall means defining a chamber, (b) a closure means for said housing wall means, said closure having a low pressure outside surface and a high pressure inside surface, said closure means having at least one opening therethrough for at least one connector means, and at least one additional opening therethrough for connection to a source of pressurizing fluid, (c) connector means being separate from and non-integral with but attachable to and detachable from said closure at or through said inside surface, said connector means comprising (aa) at least one conductor through said connector means to establish a connection between the chamber and an area outside of the chamber, said conductor being hermetically sealed in said connector means to prevent fluid flow through said connector means around said conductor, (bb) sealing means for fluid tight, non-integral sealing of said connector means at or through said inside surface of said closure means, (cc) holding means for holding said connector means in tight but non-integral connection with said closure means, (d) an O-ring between the closure means and the inside of the housing wall means for a fluid tight, non-integral seal.
Claim 2
Dependent Claim
193 words
Pressurizable vessel comprising (a) housing wall means defining a chamber, (b) a closure means for said housing wall means, said closure having a low pressure outside surface and a high pressure inside surface, said closure means having at least one opening therethrough for at least one connector means, and at least one additional opening therethrough for connection to a source of pressurizing fluid, (c) connector means being separate from and non-integral with but attachable to and detachable from said closure at or through said inside surface, said connector means comprising (aa) at least one conductor through said connector means to establish a connection between the chamber and an area outside of the chamber, said conductor being hermetically sealed in said connector means to prevent fluid flow through said connector means around said conductor, (bb) sealing means for fluid tight, non-integral sealing of said connector means at or through said inside surface of said closure means, (cc) holding means for holding said connector means in tight but non-integral connection with said closure means, (d) an O-ring between the closure means and the inside of the housing wall means for a fluid tight, non-integral seal.
Claim 3
Dependent Claim
116 words
Vessel in accordance with claim 1 wherein said connector means comprises (a) a high pressure gland nut threadable into the high pressure side of the closure means in said opening, said nut axially enclosing (b) a reverse threaded conduit section provided with an end cone for sealing engagement with a tapered section of said opening, said reverse threaded conduit section being provided with (c) a collar threadably engaged therewith, said collar engaging with said nut such as to press said end cone into said tapered portion of said opening when said nut is rotated into said opening, said apparatus further comprising (d) a source of pressurizing fluid connected to the additional opening through the closure means.
