Abstract
906,717. Magnetic compositions. GENERAL ELECTRIC CO. Nov. 18, 1958 [Dec. 16, 1957], No. 37057/58. Class 38 (2). In a magnetic material comprising magnetic particles coated with antimony and disposed in a metallic matrix composed and prepared as described in Specification 906,718, the matrix comprises either lead or a lead-antimony alloy containing less than 2% mercury. Reference has been directed by the Comptroller to Specification 815,919.
