Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 72 words
An immersion thermal sensor comprising a sensing element, a protective housing enclosing said sensing element, a support for said housing, said housing having one end adjacent the support and extending in one direction away from said support, and a resilient connection between said one end of the housing and an end of said support, said connection supporting said housing from said support and permitting deflection of the housing from its normal position.
Claim 2
Dependent Claim 72 words
An immersion thermal sensor comprising a sensing element, a protective housing enclosing said sensing element, a support for said housing, said housing having one end adjacent the support and extending in one direction away from said support, and a resilient connection between said one end of the housing and an end of said support, said connection supporting said housing from said support and permitting deflection of the housing from its normal position.
Claim 3
Dependent Claim 24 words
A sensor according to claim 1 further comprising a coupling affixed to an end of said connection separably joining the connection to said housing.
Claim 4
Dependent Claim 24 words
A sensor according to claim 1 further comprising a coupling affixed to an end of said connection separably joining the connection to said support.
Claim 5
Dependent Claim 51 words
An immersion thermal sensor comprising a sensing element, a protective housing enclosing said sensing element, a support for said housing, and a resilient connection comprising a helical spring between an end of the support and an end of said housing, said spring permitting deflection of the housing from its normal position.
Claim 6
Dependent Claim 51 words
An immersion thermal sensor comprising a sensing element, a protective housing enclosing said sensing element, a support for said housing, and a resilient connection comprising a helical spring between an end of the support and an end of said housing, said spring permitting deflection of the housing from its normal position.
Claim 7
Dependent Claim 44 words
An immersion thermal sensor comprising a sensing element, a protective housing enclosing said sensing element, a support for said housing, a resilient connection between the support and said housing permitting deflection of the housing from normal position and a flexible sleeve surrounding said connection.
Claim 8
Dependent Claim 44 words
An immersion thermal sensor comprising a sensing element, a protective housing enclosing said sensing element, a support for said housing, a resilient connection between the support and said housing permitting deflection of the housing from normal position and a flexible sleeve surrounding said connection.
Claim 9
Dependent Claim 11 words
A sensor according to claim 5, said sleeve comprising asbestos cloth.
Claim 10
Dependent Claim 41 words
A sensor according to claim 5 further comprising first and second couplings affixed to respective opposed ends of said connection and separably joining the connection between said housing and said support, said couplings fastened to respective opposed ends of the sleeve.
Claim 11
Dependent Claim 12 words
A sensor according to claim 7, said connection comprising a helical spring.
