  • Patent number: H454
    Abstract: A method of detecting leaks within artillery shells, bombs and other munitions is disclosed which involves the permanent in situ insertion within the munition cavity of an electrically resistive surface which varies in resistance with the adsorption thereon of leaking chemical vapors. In a typical embodiment of the invention, the electrically resistive surface is serially connected with an identical surface with an inert coating and the voltage drops across both the coated and uncoated surfaces are measured. Thereby, any changes in the resistance of the exposed surface due to factors other than adsorption thereon of leaking gases, e.g., temperature changes, are appropriately offset.
