Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
99 words
A thin wire temperature sensing device insertable in a cavity, said cavity having an element inserting end and a closed sensing end, a thin wire element sheathed in spirally convoluted flexible conduit adapted to be mounted in said cavity, and an open-ended, hollow cap adapted to be releasably lockably mounted on the cavity inserting end of said conduit, said cap having fixed therein a spiral spring having a plurality of convolutions interlaced with the convolutions of said conduit whereby constriction of said conduit upon locking of said cap grips said spring to immobilize said conduit relative to said cap.
Claim 2
Dependent Claim
99 words
A thin wire temperature sensing device insertable in a cavity, said cavity having an element inserting end and a closed sensing end, a thin wire element sheathed in spirally convoluted flexible conduit adapted to be mounted in said cavity, and an open-ended, hollow cap adapted to be releasably lockably mounted on the cavity inserting end of said conduit, said cap having fixed therein a spiral spring having a plurality of convolutions interlaced with the convolutions of said conduit whereby constriction of said conduit upon locking of said cap grips said spring to immobilize said conduit relative to said cap.
Claim 3
Dependent Claim
15 words
The structure of claim 1 in which said spring has about 10 of said convolutions.
Claim 4
Dependent Claim
94 words
A temperature sensing device insertable in a hollow adapter and well having a bottom, said device having an element inserting end and a sensing end, a spirally convoluted flexible conduit sheathed sensing element insertably mounted in said adapter and well, and an open-ended, hollow cap releasably, lockably mounted on said adapter inserting end, said cap having fixed therein a spiral spring having a plurality of convolutions interlaced with the convolutions of said conduit whereby constriction of said conduit upon locking of said cap grips said spring to immobilize said conduit relative to said cap.
Claim 5
Dependent Claim
94 words
A temperature sensing device insertable in a hollow adapter and well having a bottom, said device having an element inserting end and a sensing end, a spirally convoluted flexible conduit sheathed sensing element insertably mounted in said adapter and well, and an open-ended, hollow cap releasably, lockably mounted on said adapter inserting end, said cap having fixed therein a spiral spring having a plurality of convolutions interlaced with the convolutions of said conduit whereby constriction of said conduit upon locking of said cap grips said spring to immobilize said conduit relative to said cap.
Claim 6
Dependent Claim
14 words
The structure of claim 3 in which said cap is bayonet-keyed to said adapter.
Claim 7
Dependent Claim
14 words
The structure of claim 3 in which said sensing ends include a rotatary joint.
