Abstract: A disarmable firing module with a firing module housing having an opening therein; a detonator holder received in the firing module housing via the opening in the firing module housing, the detonator holder including a cavity therein; a detonator disposed in the cavity of the detonator holder; and a detonator electronics assembly housed within the firing module housing. The detonator holder is removably secured within the housing which allows the detonator to be separated from the detonator electronics assembly to disarm the firing module.

Abstract: A clamshell attachment for a crescent shaped, concave-convex log grapple converts the log grapple to a scoop or bucket type device for handling bulk material such as wood chips. It consists of a pair of concave-convex scoops pivoted together at their upper ends. A holding pin connects each grapple half to a respective scoop, with the concave portion or side of each grapple half positioned over and adjacent the convex side of a respective scoop. The only modification required of the log grapple is the addition of apertured tabs to its convex sides, the tabs receiving the holding pins.
