Abstract: A firearm suppressor includes a first section along an axis; a second section along the axis downstream of the first section, the second section having a second section twist rate; a third section along the axis downstream of the second section, the third section having a third section twist rate, the third section twist rate greater than the second section twist rate; and a fourth section along the axis downstream of the third section, the fourth section having a fourth section twist rate, the fourth section twist rate greater than the third section twist rate.

Abstract: A child-resistant cover apparatus for an electrical device in a wall comprising a housing, a cover door and a child safety latch. The housing surrounds the electrical outlet, and includes a planar baseplate having one or more openings therein for receiving the electrical device and a frame engaging the outer edges of the baseplate. The cover door is attached to the frame in a manner that permits the door to be selectively moved from an open position wherein the electrical device is exposed, and a closed position wherein the electrical device is covered by the cover door. The child safety latch is located proximate to an edge of the cover door and comprises a latch member disposed in an opening in the cover door. The latch member is selectively movable from a first unlocked position wherein a lip of the latch member is retracted into the opening in the cover door, and a second locked position wherein the lip is extended beyond the edge of the cover door and engages a slot in the frame of the housing.
