Abstract: A lock system for an enclosure comprises a locking mechanism selectively disposed in a locked or unlocked position. A first blocking pin prevents the locking mechanism from being moved to the unlocked position when disposed in a first blocking position via a first biasing mechanism. A solenoid mechanism imposes a force on the first blocking pin when in an energized state so that the first blocking pin is placed in an unblocking position. A second magnetizable blocking pin remains in contact with the first blocking pin when the solenoid mechanism is in an unenergized state. A second biasing mechanism biases the second blocking pin toward an unblocking position. During normal operation, the secondary biasing mechanism maintains the second blocking pin in its unblocking position so that the second blocking pin is separated from the first blocking pin when the solenoid mechanism is in the energized state.

Abstract: An airgun having an integrated sound suppressor with a baffle stack and barrel receiving section overmolded to a length of a barrel is provided. A shroud is disposed about a portion of the baffle stack having at least one baffle to enclose expansion gaps defined by adjacent baffles within the baffle stack.

Abstract: A locking bolt retaining mechanism for a safe is provided. The safe includes a door pivotally coupled with an enclosure housing, at least one locking bolt, a lock actuator operationally connected with the locking bolt to move it between extended and retracted positions, and a lock for preventing the lock actuator from moving the locking bolt to the retracted position. The bolt retaining system comprises a bracket guide including a guide member and an engagement member coupled to the door, and a bracket arm connected to the locking bolt. The bracket arm is slidably disposed between the guide member and engagement member of the bracket guide. Upon occurrence of an engagement event, the bracket arm engages the engagement member of the bracket guide to prevent the locking bolt from moving from the extended position thereby preventing disengagement of the locking bolt from the at least one bolt receiving aperture.

Abstract: A system for lightning-protection of an aircraft skin panel that includes a nonconductive skin panel substrate and a series of spaced apart electrically conductive strips embedded in and extending along an outer surface of the nonconductive skin panel substrate. A series of electrically conductive fasteners extend through the nonconductive skin panel substrate to affix it to the airframe of the aircraft. The fasteners are arrayed along peripheral regions of the nonconductive skin panel substrate. Each of the electrically conductive strips is in electrical communication with the aircraft airframe through at least one fastener located proximate each end region of each strip.
