Abstract
Abstract A method and apparatus for measuring the temperature of a moving elongated article is disclosed wherein radiant heat is sensed eminating from the focal axis or point of a parabolic or paraboloidal reflector beside which the article moves. An application of such is also disclosed wherein the temperature of a wire sensed in this manner is used in regulating an annealer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
The method of measuring the temperature of a moving elongated article as it gyrates about a selected path of travel comprising the steps of passing the article through a chamber cooler than the article within the bounds of a radiant heat reflective chamber wall of a substantially parabolic cross-sectional shape having a focal axis or point, the path of travel being offset from the wall focal axis or point, while sensing the magnitude of radiant heat eminating from the focal axis or point with an infrared detector.
Claim 2
Independent Claim
87 words
The method of measuring the temperature of a moving elongated article as it gyrates about a selected path of travel comprising the steps of passing the article through a chamber cooler than the article within the bounds of a radiant heat reflective chamber wall of a substantially parabolic cross-sectional shape having a focal axis or point, the path of travel being offset from the wall focal axis or point, while sensing the magnitude of radiant heat eminating from the focal axis or point with an infrared detector.
Claim 3
Independent Claim
89 words
The method of annealing a metallic wire comprising the steps of passing the wire over two spaced electrodes across which a voltage is applied, within the bounds of a radiant heat reflective wall of substantially parabolic cross-sectional or paraboloidal shape with the path of wire travel offset from the wall focal axis or point, sensing the temperature of the wire by sensing the magnitude of radiant heat emanating from the wall focal axis or point, and controlling the magnitude of the voltage as a function of sensed wire temperature.
Claim 4
Independent Claim
89 words
The method of annealing a metallic wire comprising the steps of passing the wire over two spaced electrodes across which a voltage is applied, within the bounds of a radiant heat reflective wall of substantially parabolic cross-sectional or paraboloidal shape with the path of wire travel offset from the wall focal axis or point, sensing the temperature of the wire by sensing the magnitude of radiant heat emanating from the wall focal axis or point, and controlling the magnitude of the voltage as a function of sensed wire temperature.
Claim 5
Dependent Claim
20 words
The wire annealing method of claim 2 wherein the temperature of the wire is sensed between the two spaced electrodes.
Claim 6
Dependent Claim
21 words
The wire annealing method of claim 2 or 3 wherein the temperature of the wire is sensed with an infrared detector.
