Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
A sulfuric acid prepping assembly, which comprises: a vessel member defining a chamber and having sleeve members positioned about an outer surface of said vessel member, each of said sleeve members having a channel; a cap member including an upper portion and a lower portion, said upper portion being of a diameter greater than a diameter of said vessel member and defining a supporting surface, said lower portion being of a diameter less than a diameter of said chamber thereby extending downwardly into said chamber a distance sufficient to permit collection of condensate, said upper portion including channels for alignment with said channels of said sleeves of said vessel member, said cap member including threaded channel means for receiving purge and exhaust conduit members; a ring member positioned between said supporting surface of said cap member and said vessel member; and bolt assembly means for mounting said cap member to said vessel member via said channels.
Claim 2
Dependent Claim
156 words
A sulfuric acid prepping assembly, which comprises: a vessel member defining a chamber and having sleeve members positioned about an outer surface of said vessel member, each of said sleeve members having a channel; a cap member including an upper portion and a lower portion, said upper portion being of a diameter greater than a diameter of said vessel member and defining a supporting surface, said lower portion being of a diameter less than a diameter of said chamber thereby extending downwardly into said chamber a distance sufficient to permit collection of condensate, said upper portion including channels for alignment with said channels of said sleeves of said vessel member, said cap member including threaded channel means for receiving purge and exhaust conduit members; a ring member positioned between said supporting surface of said cap member and said vessel member; and bolt assembly means for mounting said cap member to said vessel member via said channels.
Claim 3
Dependent Claim
34 words
The sulfuric acid prepping assembly as defined in claim 1 wherein said lower body portion of said cap member extends downwardly a distance of at least about 1/3 of a height of said chamber.
Claim 4
Dependent Claim
31 words
The sulfuric acid prepping assembly as defined in claim 1 wherein said vessel member is formed of a heat resistant material capable of withstanding temperatures in excess of about 300° C.
Claim 5
Dependent Claim
30 words
The sulfuric acid prepping assembly as defined in claim 1 wherein major axis of said channels of said sleeve members are parallel to a major axis of said vessel member.
Claim 6
Dependent Claim
47 words
The sulfuric acid prepping assembly as defined in claim 4 wherein said cap member is formed with cylindrically-shaped channels at a radius from said major axis substantially equal to radius of said channel of said sleeve member of said vessel member for cooperating with said mounting means.
