Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
91 words
Antiflutter and lateral stabilizer apparatus for longitudinally moving small and thin gage magnetic linear material comprising: a. an established travel path for linear material between rotatable support and guide means, and b. diametrically opposed first and second tapered magnet means mounted with their narrowest dimension adjacent to the longitudinal edges of said linear material such that the linear material passes through a magnetic field established between said magnet means causing a concentration of the magnetic lines of force in the linear material to stabilize the linear material in said travel path.
Claim 2
Dependent Claim
91 words
Antiflutter and lateral stabilizer apparatus for longitudinally moving small and thin gage magnetic linear material comprising: a. an established travel path for linear material between rotatable support and guide means, and b. diametrically opposed first and second tapered magnet means mounted with their narrowest dimension adjacent to the longitudinal edges of said linear material such that the linear material passes through a magnetic field established between said magnet means causing a concentration of the magnetic lines of force in the linear material to stabilize the linear material in said travel path.
Claim 3
Dependent Claim
13 words
Stabilizing apparatus according to claim 1 wherein said magnet means are electromagnet means.
Claim 4
Dependent Claim
16 words
StAbilizing apparatus according to claim 2 wherein said magnetic linear material comprises strip and sheet material.
Claim 5
Dependent Claim
17 words
Stabilizing apparatus according to claim 3 wherein said strip and sheet material are composed principally of steel.
Claim 6
Dependent Claim
26 words
Stabilizing apparatus according to claim 4 wherein said magnet means are positioned adjacent to and in line with the edges of said strip and sheet material.
Claim 7
Dependent Claim
19 words
Stabilizing apparatus according to claim 5 wherein the magnet means comprise the opposite poles of a single electromagnet means.
Claim 8
Dependent Claim
36 words
Stabilizing apparatus according to claim 6 wherein at least one of the poles of said magnet means is adjustable toward and away from the strip edges to aid in adjusting the magnet means to the strip.
Claim 9
Dependent Claim
26 words
Stabilizing apparatus according to claim 7 wherein said magnet means is mounted adjacent a strip passing from a molten metal coating bath to stabilize said strip.
Claim 10
Dependent Claim
34 words
Stabilizing apparatus according to claim 8 wherein said tapered magnet means are elongated along the axis of a plane disposed in the same direction as the plane of the strip in its travel path.
Claim 11
Dependent Claim
26 words
Stabilizing apparatus according to claim 9 wherein the poles of said magnet means are substantially wedge shaped at least in their portion nearest to the strip.
Claim 12
Dependent Claim
22 words

Claim 16
Dependent Claim
37 words
Hot metal coating apparatus according to claim 13 in which said electromagnet poles are positioned adjacent and in line with the strip edges slightly beyond the gas wiping means with respect to the movement of said strip.
Claim 17
Dependent Claim
24 words
