Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
112 words
The method of forming a watertight dry suit for underwater divers, said suit consisting of sections of foam core material laminated on both sides with a cover material, said sections being stitched together, including the steps of: (1) removing a portion of the cover material on the inside of the suit along a seam to expose the foam core without destroying it; (2) coating the exposed foam material with an adhesive; (3) placing a sealing strip of said cover material with foam on one side over the adhesive, with the foam side of the sealing strip in contact with the adhesive to foam a secure foam to foam seal at the seam.
Claim 2
Independent Claim
112 words
The method of forming a watertight dry suit for underwater divers, said suit consisting of sections of foam core material laminated on both sides with a cover material, said sections being stitched together, including the steps of: (1) removing a portion of the cover material on the inside of the suit along a seam to expose the foam core without destroying it; (2) coating the exposed foam material with an adhesive; (3) placing a sealing strip of said cover material with foam on one side over the adhesive, with the foam side of the sealing strip in contact with the adhesive to foam a secure foam to foam seal at the seam.
