Abstract: A reserve battery cell which includes a battery cell housing, an anode and cathode collector, and a reservoir housing which includes a quantity of electrolyte which, when applied to the anode and cathode collector, cause the battery to generate an electric current through an external load. Burst discs are located proximate the extremities of the reservoir housing. The upstream burst disc is capable of rupturing upon the application of sufficient externally applied pressure while the downstream burst disc is capable of rupturing upon the application of sufficient hydraulic pressure exerted thereon by the electrolyte. The piston is located within the reservoir housing which establishes the upstream boundary of the electrolyte and which is capable of traveling down the reservoir housing upon the application of an externally applied pressure and which is characterized as preventing electrolyte from leaking around the piston and any substantial amount of gas from entering the electrolyte through the piston body.

Abstract: An electrochemical cell having two electrodes of opposite polarity cooperating with an electrolyte solution to produce an electrical potential there between during normal operation, configured to minimize explosions upon forced discharge or charging by locating at least a portion of one electrode in close proximity to the other electrode such that a low impedance path is created between the two electrode surfaces whereby the quantity of externally imposed current flowing through the main body of the cell is minimized.

Abstract: An electronic safe arming and fuzing (ESAF) system using an accelerometer capable of sensing the acceleration of a missile and supplying an electric signal upon measuring a predetermined level of acceleration. The accelerometer signal is supplied to an electronic timer which upon the receipt of said signal initiates a timing circuit. A predetermined time after receipt of the accelerometer signal the timer causes a high voltage to be stored on a large capacitor. An electronic switch is connected between the capacitor and an exploding bridge wire detonator and will cause the energy stored in the capacitor to pass through the exploding bridge wire (EBW) upon receipt of a proper triggering signal from a trigger means. The EBW detonator is imbedded in a secondary explosive and causes said explosive to detonate without the aid of a primary explosive when said trigger signal is received.
