Fuze arming system

Claim 1

A FUZE ARMING DEVICE FOR INCORPORATION IN A MISSILE AND ADAPTED TO ARM THE MISSILE IN RESPONSE TO THE MISSILE LEAVING ITS LAUNCHER BARREL, SAID DEVICE COMPRISING: A SUBSTANTIALLY CUP-SHAPED FIRST MAGNET HOUSED IN THE BODY OF SAID MISSILE, SAID FIRST MAGNET HAVING ITS LONGITUDINAL AXIS SUBSTANTIALLY PERPENDICULAR TO THE AXIS OF SAID MISSILE, SAID FIRST MAGNET HAVING AN OPEN AND A CLOSED END, THE EXTREMITIES OF SAID OPEN END BEING SUBSTANTIALLY FLUSH WITH THE OUTER SURFACE OF SAID MISSILE BODY; A CYLINDRICAL SECOND MAGNET WITHIN SAID FIRST MAGNET, SAID SECOND MAGNET BEING SUBSTANTIALLY COAXIAL TO THE LONGITUDINAL AXIS OF SAID FIRST MAGNET, ONE END OF SAID SECOND MAGNET BEING AFFIXED TO THE INNER WALL OF SAID CLOSED END OF SAID FIRST MAGNET, THE OTHER END OF SAID SECOND MAGNET BEING FREE AND FLUSH WITH THE OUTER SURFACE OF SAID MISSILE BODY; A WIRE COIL WRAPPED IN CONVOLUTIONS AROUND SAID SECOND MAGNET SO AS TO BE INTERMEDIATE THE OUTER PERIPHERY OF SAID SECOND MAGNET AND THE INNER WALLS OF SAID FIRST MAGNET; DETONATOR RELEASE MEANS ADAPTED TO BE ACTIVATED TO RELEASE A DETONATOR FOR ROTATION TO AN ARMED POSITION IN RESPONSE TO A VOLTAGE APPLIED THERETO; AND SWITCH MEANS RESPONSIVE TO FORCES OF SET-BACK FOR ELECTRICALLY CONNECTING SAID COIL TO SAID DETONATOR RELEASE MEANS WHEN SAID MISSILE IS FIRED IN SAID BARREL; SAID BARREL PROVIDING A LOW RESISTANCE MAGNETIC PATH BETWEEN SAID EXTREMITIES OF SAID FIRST MAGNET AND SAID FREE END OF SAID SECOND MAGNET SO THAT RELATIVELY INTENSE AND CONSTANT MAGNETIC FIELD EXISTS IN SAID SECOND MAGNET WHILE SAID MISSILE IS IN SAID BARREL, SAID MAGNETIC FIELD IN SAID SECOND MAGNET DECREASING RAPIDLY WHEN SAID MISSILE LEAVES THE END OF SAID BARREL, THE RAPID DECREASE OF SAID MAGNETIC FIELD CAUSING A VOLTAGE TO BE INDUCED IN SAID COIL WHICH ACTIVATES SAID DETONATOR RELEASE MEANS, THEREBY ARMING SAID MISSILE.
