Abstract

1,187,458. Electromagnetic metal detectors. SOC. INDUSTRIELLE DE MATERIEL ELECTROMAGNETIQUE S.A. July 7, 1967 [July 12, 1966], No.31325/67. Heading G1N. The coils of a variable inductance or inductive coupling, metal detector are formed by a printed circuit "board". The coils may be mounted in boxes for mechanical protection and electrical screening, above and below a conveyer belt. Alternatively the printed-circuit-board may be rolled into a tube. A coil or grid may be printed on the back of the board for compensation of electrostatic screening.
