Abstract
Abstract An explosive controlled rectifier, an explosive AND/NAND logic element and a three-input-seven-output explosive logic element. The three-input-seven-output explosive logic element comprises four explosive AND/NAND logic elements. Each explosive AND/NAND logic element has two inputs and three outputs and includes one explosive controlled rectifier.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
157 words
An explosive logic circuit comprising: first and second destructive crossovers; said destructive crossovers comprising two explosive paths which cross each other generally orthogonally and the portions of said paths cross are narrowed so that a detonation wave traveling along one of said paths will not be transferred along the other of said paths due to a ''''corner effect;'''' an explosive controlled rectifier; first and second explosive paths for receiving explosive inputs into said circuit; said first and second paths each branching into first and second branches; said first path crossing said first branch of said second path at said first destructive crossover; said first branch of said second path crossing said first branch of said first path at said second destructive crossover; said second branch of said second path comprising a gating path for said explosive controlled rectifier and said second branch of said first path being connected to the fore end of said explosive controlled rectifier.
Claim 2
Dependent Claim

An explosive logic circuit comprising: first and second destructive crossovers; said destructive crossovers comprising two explosive paths which cross each other generally orthogonally and the portions of said paths cross are narrowed so that a detonation wave traveling along one of said paths will not be transferred along the other of said paths due to a ''''corner effect;'''' an explosive controlled rectifier; first and second explosive paths for receiving explosive inputs into said circuit; said first and second paths each branching into first and second branches; said first path crossing said first branch of said second path at said first destructive crossover; said first branch of said second path crossing said first branch of said first path at said second destructive crossover; said second branch of said second path comprising a gating path for said explosive controlled rectifier and said second branch of said first path being connected to the fore end of said explosive controlled rectifier.
Claim 3
Dependent Claim
210 words
An explosive logic circuit comprising: first, second and third paths of explosive material for receiving explosive inputs into said circuit; first, second, third and fourth explosive AND/NAND logic elements; said paths being connected to said first and second logic elements; said first path being the source input for said first logic element; said second path being the gate input for said first logic element; said third path being the gate input for said second logic element; the gate output of said first logic element being connected to the source input of said third logic element; the source output of said firSt logic element being connected to the source input of said fourth logic element; the simultaneous-input output of said first logic element being connected to the source input of said second logic element; the gate output of said second logic element being connected to the gate input of said third logic element; and the gate output of said third logic element being connected to the gate input of said fourth logic element; whereby explosive inputs into either of said first, second or third paths alone, any two of said first, second or third paths simultaneously or said first, second and third paths simultaneously can produce at least seven different outputs.
Claim 4
Dependent Claim
210 words
An explosive logic circuit comprising: first, second and third paths of explosive material for receiving explosive inputs into said circuit; first, second, third and fourth explosive AND/NAND logic elements; said paths being connected to said first and second logic elements; said first path being the source input for said first logic element; said second path being the gate input for said first logic element; said third path being the gate input for said second logic element; the gate output of said first logic element being connected to the source input of said third logic element; the source output of said firSt logic element being connected to the source input of said fourth logic element; the simultaneous-input output of said first logic element being connected to the source input of said second logic element; the gate output of said second logic element being connected to the gate input of said third logic element; and the gate output of said third logic element being connected to the gate input of said fourth logic element; whereby explosive inputs into either of said first, second or third paths alone, any two of said first, second or third paths simultaneously or said first, second and third paths simultaneously can produce at least seven different outputs.
