Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
70 words
Method of finishing a high temperature resistant plate having projections extending therefrom for use in the manufacture of glass fibers comprising: (a) reinforcing the projections of the plate with a material which can be removed without damage to the reinforced projections; (b) cutting off the end regions of the reinforced projections such that the projections extending from the plate are each of a desired length; and (c) removing the material.
Claim 2
Dependent Claim
70 words
Method of finishing a high temperature resistant plate having projections extending therefrom for use in the manufacture of glass fibers comprising: (a) reinforcing the projections of the plate with a material which can be removed without damage to the reinforced projections; (b) cutting off the end regions of the reinforced projections such that the projections extending from the plate are each of a desired length; and (c) removing the material.
Claim 3
Dependent Claim
15 words
The method of claim 1 wherein the projections are all cut to the same length.
Claim 4
Dependent Claim
29 words
The method of claim 1 wherein the projections are of a tubular shape and are reinforced by encapsulating the inside and the outside of the projections in the material.
Claim 5
Dependent Claim
14 words
The method of claim 2 wherein the entire plate is encapsulated by the material.
Claim 6
Dependent Claim
15 words
The method of claim 1 wherein the material reinforcing the projections is a resinous material.
Claim 7
Dependent Claim
37 words
The method of claim 4 wherein the resinous material is removed from the projections by heating the reinforced plate to a sufficient temperature below the distortion temperature of the plate to burn the material from the projections.
Claim 8
Dependent Claim
17 words
The method of claim 1 wherein the material reinforcing the projections is a low melting temperature alloy.
Claim 9
Dependent Claim
18 words
The method of claim 6 wherein the alloy material is removed by melting the material from the projections.
Claim 10
Dependent Claim
15 words
The method of claim 1 wherein the projections are cut by mechanically milling the projections.
Claim 11
Dependent Claim
30 words
The method of claim 1 including the steps of placing the plate in a vacuum chamber, evacuating the chamber and reinforcing the projections with the material in the evacuated chamber.
Claim 12
Dependent Claim
32 words
The method of claim 1 including the steps of collecting the cuttings from the cutting step and removing the material from the cuttings to recover the cut off portions of the projections.
