Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
Apparatus for measuring the temperature of a rotary body, said rotary body being characterized by at least one temperature sensing radially extending slot formed continuously around the periphery thereof with the slot having a peripheral open face and defined by two spaced-apart side walls formed in the periphery of the rotary body at an optimum distance along the axial length of the rotary body and of sufficient breadth and depth to accommodate at least one electrical temperature measuring element of the type for providing an electrical output indication of temperature, and fixed mounting means spaced cloSely adjacent the periphery of the rotary body for supporting at least one of said temperature measuring elements to ride within the open face of the slot as the body is rotated.
Claim 2
Dependent Claim
127 words
Apparatus for measuring the temperature of a rotary body, said rotary body being characterized by at least one temperature sensing radially extending slot formed continuously around the periphery thereof with the slot having a peripheral open face and defined by two spaced-apart side walls formed in the periphery of the rotary body at an optimum distance along the axial length of the rotary body and of sufficient breadth and depth to accommodate at least one electrical temperature measuring element of the type for providing an electrical output indication of temperature, and fixed mounting means spaced cloSely adjacent the periphery of the rotary body for supporting at least one of said temperature measuring elements to ride within the open face of the slot as the body is rotated.
Claim 3
Dependent Claim
40 words
An apparatus according to claim 1, wherein the opening of said slot is closed by a heat insulator and the temperature measuring element is supported by the heat insulator so that the temperature sensing portion thereof rides in the slot.
Claim 4
Dependent Claim
51 words
An apparatus according to claim 1, wherein said rotary member is in the form of a cup-shaped cylindrical heating body with the slot being in the form of an annular ring around the outer periphery thereof, and a stationary heating unit is positioned in the space within said cup-shaped heating body.
Claim 5
Dependent Claim
40 words
An apparatus according to claim 3, wherein the opening of said slot is closed by a heat insulator and the temperature measuring element is supported by the heat insulator so that the temperature sensing portion thereof rides in the slot.
Claim 6
Dependent Claim
25 words
An apparatus according to claim 4, wherein there are a plurality of temperature elements positioned to ride within the slot as the body is rotated.
Claim 7
Dependent Claim
25 words
An apparatus according to claim 1, wherein there are a plurality of temperature elements positioned to ride within the slot as the body is rotated.
