Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
84 words
In the process of manufacture of an electromagnetic radiation seal wherein a strip of elastomeric material is surrounded by a tube of woven metal fibers and formed into a roughly toroidal shape, the improvement comprising; confining the roughly formed toroidal seal in a mold having the desired finished shape and size so as to form a gasket and mold assembly; heating the gasket and mold assembly to about 350° F.; cooling the assembly to about 70° F.; and removing the seal from the mold.
Claim 2
Dependent Claim
84 words
In the process of manufacture of an electromagnetic radiation seal wherein a strip of elastomeric material is surrounded by a tube of woven metal fibers and formed into a roughly toroidal shape, the improvement comprising; confining the roughly formed toroidal seal in a mold having the desired finished shape and size so as to form a gasket and mold assembly; heating the gasket and mold assembly to about 350° F.; cooling the assembly to about 70° F.; and removing the seal from the mold.
Claim 3
Independent Claim
80 words
The method of forming an annular flexible radiation seal comprising: placing a finite strand of vulcanizable elastomeric material within a section of a shielding tube of woven metal fibers; fastening the ends of the shielding tube so that the ends of the elastomeric material are joined to form a work piece assembly; placing the workpiece assembly in a mold which confines the workpiece assembly to a desired final shape; and heating the mold and workpiece assembly to about 350° F.
Claim 4
Independent Claim
80 words
The method of forming an annular flexible radiation seal comprising: placing a finite strand of vulcanizable elastomeric material within a section of a shielding tube of woven metal fibers; fastening the ends of the shielding tube so that the ends of the elastomeric material are joined to form a work piece assembly; placing the workpiece assembly in a mold which confines the workpiece assembly to a desired final shape; and heating the mold and workpiece assembly to about 350° F.
Claim 5
Dependent Claim
37 words
The method of claim 2 further including; holding the mold and workpiece assembly at about 350° F. for about 3-10 seconds; and rapidly cooling the assembly to about 70° F. before removing the workpiece from the mold.
