BLASTING LOGICAL CIRCUIT Russian patent published in 2005 - IPC

FIELD: discrete transducers on detonation logical elements for remote authorized blast of explosive charges.

SUBSTANCE: the blasting logical circuit has a board with two inputs and one output interconnected by detonating rods forming a longer and shorter branches between the first input and the output with joining-on of the second input to the shorter branch. Actuating elements disturbing the detonation coupling are installed at the joints of the longer and shorter branches and the second input. The detonating rods are positioned on both sides of the board, and through holes are made in the board, the actuating elements disturbing the detonation coupling are made in the form of a receiving charge and an inert obstacle adjoining it and located on the side of the destructed detonating rod for motion under the action of the blast products of the receiving charge, the detonation ducts and the receiving charge are made of precipitated explosive.

EFFECT: reduced dimensional and mass characteristics.
