Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
69 words
In measuring apparatus for measuring a condition in a fluid, a metallic body having an opening at one end, a thin walled metallic closure for said opening having an outer face exposed to the fluid, and a temperature sensitive electrical element engaged within the inner face of said closure, said temperature sensitive element being held in engagement with said inner face by an electrical and heat conductive adhesive cement.
Claim 2
Dependent Claim
69 words
In measuring apparatus for measuring a condition in a fluid, a metallic body having an opening at one end, a thin walled metallic closure for said opening having an outer face exposed to the fluid, and a temperature sensitive electrical element engaged within the inner face of said closure, said temperature sensitive element being held in engagement with said inner face by an electrical and heat conductive adhesive cement.
Claim 3
Dependent Claim
66 words
In measuring apparatus for measuring a condition in a fluid, a metallic body having an opening at one end, a thin walled resilient metallic closure disc for said opening having an outer face exposed to the fluid, and a temperature sensitive electrical element engaged with the inner face of said closure, said disc providing a resilient force for maintaining contact between said disc and said element.
Claim 4
Dependent Claim
66 words
In measuring apparatus for measuring a condition in a fluid, a metallic body having an opening at one end, a thin walled resilient metallic closure disc for said opening having an outer face exposed to the fluid, and a temperature sensitive electrical element engaged with the inner face of said closure, said disc providing a resilient force for maintaining contact between said disc and said element.
Claim 5
Dependent Claim
79 words
In measuring apparatus for measuring a condition in a fluid, a metallic body having an opening at one end, a thin walled metallic closure for said opening having an outer face exposed to the fluid, and a temperature sensitive electrical element engaged with the inner face of said closure, said closure having a thermal insulating coating on the outer face provided with a window facing said element for heat transfer through the window between the fluid and said element.
Claim 6
Dependent Claim
