Magnetic mine firing circuit

Patent ·
OSTI ID:6377158
This patent describes a control device. It comprises: a circuit for deriving a direct current signal which is a measure of change sin the strength of a magnetic field, a first gas tube channel connected to respond to a change in the signal in one direction, a second gas tube channel parallel with the first and connected to respond to a change in the signal in the opposite direction, a network for retaining and combining the outputs of the channels, a third gas tube channel connected to respond to a predetermined value of the output of the network, a utilization circuit forming the output of the third channel. The network comprising three resistor capacitor combinations connected in star, one of the combinations being connected in the output circuit of the first gas tube channel, another of the combinations being connected in the output of the second gas tube channel, and the values of the elements of the combinations being chosen to fire the third gas tube channel in response to firing of one of either the first or the second channels within a predetermined period after firing of the other of the first or second channels.
