Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
71 words
A method of soldering the side seams of tinplate can bodies which comprises providing a sulfur-resistant solder consisting essentially of about 0.1 to about 0.5 percent by weight indium, about 0.1 to 0.5 percent by weight bismuth, the remainder being tin, maintaining the solder in a molten condition, applying the molten solder to the side seam of the can body to provide the side seam with a layer of the solder.
Claim 2
Independent Claim
71 words
A method of soldering the side seams of tinplate can bodies which comprises providing a sulfur-resistant solder consisting essentially of about 0.1 to about 0.5 percent by weight indium, about 0.1 to 0.5 percent by weight bismuth, the remainder being tin, maintaining the solder in a molten condition, applying the molten solder to the side seam of the can body to provide the side seam with a layer of the solder.
Claim 3
Dependent Claim
20 words
The method of claim 1 wherein indium is present in the solder at a concentration of 0.15-0.30 percent by weight.
Claim 4
Dependent Claim
19 words
The method of claim 1 wherein bismuth is present in the solder at 0.15 to 0.30 percent by weight.
