Abstract
Abstract A housing has an interior provided with two axially spaced and aligned openings, and is connectable in sealing relationship with a wall of the pressure vessel, so that one of the openings is in registry with a viewing port provided in this wall. A spherical, cylindrical or conical body having a bore is sealingly accommodated in the interior of the housing and can be turned to and from a position in which its bore registers with the openings and, hence, with the port. Sight glasses, lenses or the like are sealingly mounted in the bore and permit viewing of the interior of the pressure vessel when the body is in the position in which the bore registers with the openings.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
171 words
An arrangement for viewing the interior of a pressure vessel which has a wall provided with a viewing port, comprising a housing having an interior provided with two axially spaced and aligned openings; connecting means for sealingly connecting said housing to said wall so that one of said openings registers with said viewing port; a body of revolution having a bore provided with two axially spaced open ends and being sealingly accommodated in said interior of said housing for turning to and from a position in which said bore registers with said openings; optical means sealingly mounted in said bore for permitting viewing of the interior of said pressure vessel when said body is in said position thereof, said optical means comprising a first optical element sealingly mounted in said bore in the region of one of said open ends, and a second optical element sealingly accommodated in said bore in the region of the other of said open ends; and retaining means retaining said second optical element in said bore.
Claim 2
Dependent Claim
171 words
An arrangement for viewing the interior of a pressure vessel which has a wall provided with a viewing port, comprising a housing having an interior provided with two axially spaced and aligned openings; connecting means for sealingly connecting said housing to said wall so that one of said openings registers with said viewing port; a body of revolution having a bore provided with two axially spaced open ends and being sealingly accommodated in said interior of said housing for turning to and from a position in which said bore registers with said openings; optical means sealingly mounted in said bore for permitting viewing of the interior of said pressure vessel when said body is in said position thereof, said optical means comprising a first optical element sealingly mounted in said bore in the region of one of said open ends, and a second optical element sealingly accommodated in said bore in the region of the other of said open ends; and retaining means retaining said second optical element in said bore.
Claim 3
Dependent Claim

Claim 5
Dependent Claim
15 words
An arrangement as defined in claim 1, wherein said body is of substantially conical configuration.
Claim 6
Dependent Claim
30 words
An arrangement as defined in claim 1, wherein said body has an interior and an exterior surface; and further comprising cooling means for cooling at least one of said surfaces.
Claim 7
Dependent Claim
29 words
An arrangement as defined in claim 1; and further comprising means exteriorly of said housing and operative for effecting turning of said body to and from said position thereof.
Claim 8
Dependent Claim
25 words
An arrangement as defined in claim 1, wherein said retaining means are releasable retaining means which releasably retain said second optical element in said bore.
Claim 9
Dependent Claim
138 words
An arrangement for viewing the interior of a pressure vessel which has a wall provided with a viewing port, comprising a housing having an interior provided with two axially spaced and aligned openings; connecting means for sealingly connecting said housing to said wall so that one of said openings registers with said viewing port; a body of revolution having a bore and being sealingly accommodated in said interior of said housing for turning to and from a position in which said bore registers with said openings, said body having an outer surface which defines with an inner surface of said housing a gap; cooling means for admitting cooling fluid into said gap; and optical means sealingly mounted in said bore for permitting viewing of the interior of said pressure vessel when said body is in said position thereof.
Claim 10
Dependent Claim
138 words
An arrangement for viewing the interior of a pressure vessel which has a wall provided with a viewing port, comprising a housing having an interior provided with two axially spaced and aligned openings; connecting means for sealingly connecting said housing to said wall so that one of said openings registers with said viewing port; a body of revolution having a bore and being sealingly accommodated in said interior of said housing for turning to and from a position in which said bore registers with said openings, said body having an outer surface which defines with an inner surface of said housing a gap; cooling means for admitting cooling fluid into said gap; and optical means sealingly mounted in said bore for permitting viewing of the interior of said pressure vessel when said body is in said position thereof.
Claim 11
Dependent Claim
23 words
An arrangement as defined in claim 8; and further comprising means for measuring and indicating the temperature and pressure prevailing in said gap.
Claim 12
Dependent Claim
149 words
An arrangement for viewing the interior of a pressure vessel which has a wall provided with a viewing port, comprising a housing having an interior provided with two axially spaced and aligned openings; connecting means for sealingly connecting said housing to said wall so that one of said openings registers with said viewing port; a hollow body of revolution having a bore and being sealingly accommodated in said interior of said housing for turning to and from a portion in which said bore registers with said openings; a substantially tubular element extending through said body, at least in part defining said bore and defining with the hollow interior of said body a clearance; cooling means for admitting a cooling fluid into said clearance; and optical means sealingly mounted in said bore for permitting viewing of the interior of said pressure vessel when said body is in said position thereof.
