Abstract

1,156,142. Target. M.B. METALS Ltd. 29 Nov., 1966 [1 Sept., 1965], No. 37432/65. Heading F3X. [Also in Divisions G1 and H1] An apparatus adapted to respond to the flight of an electrically conductive missile comprises one or more insulating sheets 10 with two sets of printed circuit conductors 11, 12 and 13, 14 insulated from each other but closely spaced so that the passage of a missile through the sheet bridges conductors 12, 14 to complete a circuit between terminals 15, 16. Sheet 10 may be a thin plastic sheet or a more rigid sheet. The sets of conductors may be in a spiral pattern. Two printed circuit sheets may be mounted in the path of a missile in conjunction with a timer to determine the average speed of the missile between the sheets.
