[1-3] This case charges infringement of patent

No. 660,341, issued to Joseph Sachs for a safety fuse in an electric circuit. It was decided in the District Court by Judge Cross, whose full and excellent discussion of the questions at issue has recently been reported in 201 Fed. 356. No question was presented to us on appeal that was not satisfactorily disposed of by him, and upon his opinion, therefore, we affirm the decree.
