This appeal by the plaintiff below is from a judgment holding United States Letters Patent 2,828,166 invalid and not to have been infringed by defendant-appellee. All issues of law and fact were exhaustively considered and decided by the District Court in a published opinion, 247 F.Supp. 469 (1965). Upon thorough consideration of the appeal, including *989 briefs and fine arguments here, we are left in no doubt that the case was correctly decided. This being so, no worthwhile service is to be accomplished by any paraphrasing of an opinion already published.

The judgment of the District Court, therefore, is

Affirmed.
