Abstract:
A time delay apparatus for use with a downhole tool in a wellbore casing. In an exemplary embodiment, the apparatus includes an electronic circuit comprising a timer, a fusible link, a split spool device that includes a center pin held in place in a restrained position with a spool and a spring element surrounding the spool. A pressure applied to a trigger device, such as a rupture disk, activates a pressure switch and starts a timer, configured with a preset countdown time, in the electronic circuit. On expiration of the timer, the timer block of the electronic circuit generates a signal to cause breaking of the fusible link and releasing of the spring element such that the center pin of the split spool travels to a functional position and activates the downhole tool.

Claim (Index 4):
The time delay apparatus of  claim 1 , wherein the fusible link comprises a link of an electrically conductive material that degrades as current passes through it.
