Abstract
An expulsion type fuse is taught which has an opening in the bottom thereof from which hot gases may exit during a fusing operation. The hot gases are provided to a condenser which is disposed adjacent the exit of the expulsion fuse. The disposition of the condenser relative to the fuse is such that none of the gas escapes to any region outside of the expulsion fuse other than the condenser. The condenser has a central axial opening around which is an annularly disposed copper screen. Around the outer periphery of the copper screen is disposed a relatively thin layer of plastic material which may rupture because of pressure or temperature. Around the plastic material is disposed quartz sand. All of the above are disposed within a cylindrical container. When gas exits from the expulsion fuse it is cooled by the copper wire. This causes the precipitation of water from the hot gas. The remaining portion of the gas may attain a relatively high pressure causing the thin plastic material to rupture or be thermally broken thus venting the gas into the sand which surrounds the plastic material. The sand absorbs the energy of the gas. The expulsion fuse and condenser may be disposed inside of a submersible container.
