Abstract
An accoustically detonated explosively separable link comprising a pair of bolt assemblies mounted in spaced operative relation within the separable link parts, each of which includes a bolt having a cavity therein. An explosive is provided in each cavity and an electrically actuated exploding bridge wire is connected with each explosive for detonating the same. A miniaturized acoustical receiver assembly is mounted within the link parts and includes a hydrophone for receiving a transmitted acoustical detonation signal, batteries and circuitry operatively connected with the hydrophone, the batteries and exploding bridge wires for conducting an electrical current from the batteries to the exploding bridge wires in response to the hydrophone receiving a transmitted acoustical detonation signal. A water pressure resistant container is mounted within the link parts between the pair of spaced bolt assemblies for containing the batteries and circuitry including the operative connections thereof free from contact with water under pressure and for retaining the hydrophone in a position of proximity to water under pressure such as to receive an acoustical detonation signal transmitted throu…
