Abstract: A shaped charge retention and barrier clip according to the invention includes a barrier ring means for preventing damage to the interior of a perforating gun, and retention means for securing the barrier ring means and the shaped charge to a carrier strip disposed in the perforating gun.

Abstract: An explosive safe-arming apparatus for use with a perforating gun which includes a fixed barrier disposed between a detonator explosive and a booster explosive, and a movable barrier disposed between laterally facing portions of the detonator and booster explosives. Upon actuating the movable barrier, either a predetermined perforator disarming operating position or perforator arming operating position are obtained.

Abstract: In the representative embodiments of the safe-handling arming apparatus of the present invention disclosed herein, a spring-biased indicator is cooperatively arranged on an enclosed-carrier perforating gun for visually representing whether an obscured or secluded detonator enclosed within the carrier is either in an ineffectual or "safe" status or is in an effective or "armed" status in readiness for detonating one or more shaped explosive charges in the gun. In one embodiment of the new and improved arming apparatus of the present invention, a unique arrangement is provided for releasably retaining a selectively-movable detonator in either of two predetermined operating locations. In another embodiment of the invention, the detonator is instead fixed and isolated by a selectively-movable barrier whose presence or absence is shown by the indicator.
