Abstract

Abstract An ordnance fuze circuit having an energy storage device for storing an applied energy signal. A plurality of unidirectionally conducting RC circuits connected to the energy storage device provide time delays corresponding to the magnitude and polarity of the applied signal in firing gas diodes to actuate switches which provide for discharge of the stored energy through a detonator to explode the ordnance device. A switch connected between the energy storage device and the predetermined energy signal source prevents discharge of the energy storage device back to the energy source.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 151 words
An ordnance fuze circuit comprising, means for storing electrical energy of a polarity and magnitude corresponding to the polarity and magnitude of a predetermined electrical signal applied thereto, detonator means actuable by said stored electrical energy, switching means for normally rendering said detonator means nonresponsive to said stored electrical energy, means for selectively interrupting the application of said predetermined electrical signAl to said electrical energy storing means, electroresponsive means actuable for operating said switching means to render said detonator means responsive to said stored electrical energy, a pair of diverse polarity responsive circuit means interconnecting said energy storage means and said electroresponsive means each for activating said electroresponsive means after respective predetermined times following the application of said predetermined electrical signal to said electrical energy storing means, and impact responsive means for effecting actuation of said detonator means by said stored electrical energy subsequent to the actuation of said electroresponsive means.
Claim 2
Dependent Claim 151 words
An ordnance fuze circuit comprising, means for storing electrical energy of a polarity and magnitude corresponding to the polarity and magnitude of a predetermined electrical signal applied thereto, detonator means actuable by said stored electrical energy, switching means for normally rendering said detonator means nonresponsive to said stored electrical energy, means for selectively interrupting the application of said predetermined electrical signAl to said electrical energy storing means, electroresponsive means actuable for operating said switching means to render said detonator means responsive to said stored electrical energy, a pair of diverse polarity responsive circuit means interconnecting said energy storage means and said electroresponsive means each for activating said electroresponsive means after respective predetermined times following the application of said predetermined electrical signal to said electrical energy storing means, and impact responsive means for effecting actuation of said detonator means by said stored electrical energy subsequent to the actuation of said electroresponsive means.
