  • 3873051  Time delay release device by Rudolph S. Kennedy.  Filing date: Mar 26, 1974.
    [Annotation: Adhesive forces are overcome for release; Velcro is then mentioned.  Reader thought: expansion by wetness going dry for shrinkage is another method that one might try for delayed trigger or release.  For a dissolving method for delayed release, see  5072899 ]
