Abstract
A sweep device for river mines of the command type is described. The devicemploys two spaced, parallel blades which support the sweep device on the bottom of the river as it is towed therealong. The blades constitute laminated cutting elements which provide a signal of the presence of a command wire as it is severed on contact, as well as serve as electrodes for supplying an electric signal to sweep the mine. An electrical circuit is also described to process the signals from the blades, so as to distinguish between small metallic debris and metallic bodies bridging the two blades.
