Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
57 words
An electrical temperature sensor for sensing the temperature of a body, said sensor comprising closely wound wire of a material having an electrical resistance which varies in magnitude in accordance with temperature variations, a film of blacking comprising polyvinylacetate on said wire and glass insulation covering said wire, the insulated wire being directly mounted on said body.
Claim 2
Dependent Claim
57 words
An electrical temperature sensor for sensing the temperature of a body, said sensor comprising closely wound wire of a material having an electrical resistance which varies in magnitude in accordance with temperature variations, a film of blacking comprising polyvinylacetate on said wire and glass insulation covering said wire, the insulated wire being directly mounted on said body.
Claim 3
Dependent Claim
63 words
An electrical temperature sensor for sensing the temperature of a body, said sensor comprising wire of a material having an electrical resistance which varies in magnitude in accordance with temperature variations, glass insulation covering said wire, and a metallized outer surface on said insulation, the insulated wire being directly mounted on and affixed to said body in good heat conducting relationship by solder.
Claim 4
Dependent Claim
63 words
