ABSTRACT:
Signal transmission devices contain within a housing (12) at least a pair of signal transmission lines, e.g., signal transmission tubes (16, 18) having respective tube ends (16a, 18a) disposed within the housing to provide at least one input tube and at least one output tube. Delay train means (22) are interposed between at least one of the tubes and a detonator charge (20) contained at the closed or active end (12a) of the housing. Alternatively, both the input and output tubes may have a delay train (22', 22'') interposed between it and the detonator charge. In another embodiment, a signal transfer charge (28) may connect the input and output tubes (16'', 18'') in signal transfer relation to each other. In operation, selected delays may be attained between initiation of the detonator charge and one or both of ignition of the delay train means and generation of an output relay signal in the output tube. A plurality of relay and initiator devices (34) may be connected in sequence by signal transfer connectors (46) connecting tubes (42, 40) in signal transfer relationship.
