Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
142 words
IN A DETONATION DEVICE WHEREIN DETONATION IS ACCOMPLISHED BY CLOSING A CIRCUIT UPON AN ELECTRICALLYRESPONSIVE EXPLOSIVE ELEMENT UPON THE APPLICATION OF A PARTICULAR VOLTAGE TO THE CIRCUIT, THE COMBINATION OF: A FIRST CONDUCTOR, A SECOND CONDUCTOR HAVING A FEMALE PORTION FOR RECEIVING THE FIRST CONDUCTOR, AND FIRST CERAMIC MATERIAL FUSED TO THE SECOND CONDUCTOR IN ENVELOPING RELATIONSHIP TO THE FIRST CONDUCTOR, SECOND CERAMIC MATERIAL FUSED TO THE FIRST CONDUCTOR AND DISPOSED BETWEEN THE FIRST CONDUCTOR AND THE FEMALE PORTION OF THE SECOND CONDUCTOR AT A POSITION AT WHICH THE FIRST CERAMIC MATERIAL IS FUSED TO THE SECOND CONDUCTOR, THE SECOND CERAMIC MATERIAL BEING FORMED BY TWO PORTIONS SEPARATED BY A GAP TO PROVIDE A SPARK BETWEEN THE FIRST AND SECOND CONDUCTORS AND ACROSS THE GAP TO OBTAIN A DETONATION OF THE DEVICE UPON THE APPLICATION OF THE PARTICULAR VOLTAGE THROUGH THE CIRCUIT.
