Blasting signal transmission tube delay unit |
| abstract |
A transmission tube signal delay assembly comprising a delay element containing a shaped delay composition having a preselected combustion time from a first side of the delay element to a second side of the delay element; a first transition element adjacent to the delay element at the first side for transferring a transmission tube signal to the delay element; and a second transition element adjacent to the delay element at the second side for transferring a signal from the delay element to a transmission tube, each of the transition elements comprising a shaped transition composition. Also, a method for delaying a transmission tube signal delay unit having a housing with a plurality of openings for receiving portions of signal transmission tube having interior-exposing opening means for securing the signal transmission tubes in the housing openings; and the signal delay assembly mounted in the housing with each of the transition elements positioned between the delay element and one of the housing openings for transferring a signal between the delay element and each of the signal transmission tubes. |
