Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
84 words
A seal for use with a thermocouple assembly having a plurality of sheathed thermocouple leads, said seal comprising: a plate having a plurality of thermocouple receiving bores therethrough; tube means fixed in at least a plurality of said thermocouple receiving bores, each of said tube means having one end extending outwardly of said plate; and sheathed thermocouple leads extending through at least some of said tube means, each of said sheathed thermocouple leads being fixed to said one end of an associated tubes means.
Claim 2
Dependent Claim
84 words
A seal for use with a thermocouple assembly having a plurality of sheathed thermocouple leads, said seal comprising: a plate having a plurality of thermocouple receiving bores therethrough; tube means fixed in at least a plurality of said thermocouple receiving bores, each of said tube means having one end extending outwardly of said plate; and sheathed thermocouple leads extending through at least some of said tube means, each of said sheathed thermocouple leads being fixed to said one end of an associated tubes means.
Claim 3
Dependent Claim
22 words
The device of claim 1 wherein said sheathed thermocouple leads are affixed to their said associated tube means by brazed connection means.
Claim 4
Independent Claim
102 words
A device for sealingly closing an entry to a pressure vessel wherein said pressure vessel includes a thermocouple assembly, said assembly including a plurality of sheathed thermocouples, at least partially inserted within said vessel, said device comprising: plate means having a plurality of thermocouple-passing apertures for receiving individual ones of said sheathed thermocouples; tubes positioned within at least some of said apertures, each of said tubes having one end extending beyond said plate means; sheathed thermocouples passing through at least some of said tubes, each of said sheathed thermocouples being joined to said one end of an associated one of said tubes.
Claim 5
Independent Claim
102 words
A device for sealingly closing an entry to a pressure vessel wherein said pressure vessel includes a thermocouple assembly, said assembly including a plurality of sheathed thermocouples, at least partially inserted within said vessel, said device comprising: plate means having a plurality of thermocouple-passing apertures for receiving individual ones of said sheathed thermocouples; tubes positioned within at least some of said apertures, each of said tubes having one end extending beyond said plate means; sheathed thermocouples passing through at least some of said tubes, each of said sheathed thermocouples being joined to said one end of an associated one of said tubes.
Claim 6
Dependent Claim
20 words
The device of claim 3 and including a pair of centrally bored flanged members clampingly receiving said plate means therebetween.
Claim 7
Dependent Claim
18 words
The device of claim 4 wherein one of said flanged members is releasably connected to said plate means.
Claim 8
Dependent Claim
22 words
The device of claim 5 wherein said plate means includes means for fixedly receiving a flexible support carried by said thermocouple assembly.
Claim 9
Independent Claim
60 words
A method of fabricating a thermocouple seal comprising: positioning open-ended tubes within at least some apertures of a multi-apertured plate means such that one end of each of said tubes extends beyond said plate means; passing sheathed thermocouple means through each said tube; and brazing each said thermocouple means to said one end of an associated one of said tubes.
Claim 10
Independent Claim
60 words
A method of fabricating a thermocouple seal comprising: positioning open-ended tubes within at least some apertures of a multi-apertured plate means such that one end of each of said tubes extends beyond said plate means; passing sheathed thermocouple means through each said tube; and brazing each said thermocouple means to said one end of an associated one of said tubes.
Claim 11
Dependent Claim
20 words
The device of claim 3 wherein each of said sheathed thermocouples are joined to said associated tube ends by brazing.
Claim 12
Dependent Claim
33 words
The device of claim 3 wherein some of said tubes extend from one face of said plate means and the remainder of said tubes extend from the opposite face of said plate means.
