Abstract

1494288 Devices for detonating magnetic mines FORENADE FABRIKSVERKEN 21 Oct 1975 43186/75 Heading F3A [Also in Division G1] A device for detonating a magnetic, sea or land, mine in response to the approach of a combat vehicle comprises, a spaced pair of opposedly connected pick-up coils for generating signals proportional to the time rate of change in the magnetic gradient therebetween, a firing means for detonating, in use, the mine, and amplifying means for amplifying and transferring the signals to the firing means, the amplifier having a finite gain at zero frequency and a corner frequency so selected that only at low frequencies is the gain sufficient to operate the firing means, whereby the device is sensitive only to conventional combat vehicles whose relatively slow movement generate signals having a predominantly low frequency content.
