Abstract: There is disclosed a window well cover having a base member which has a horizontal and vertical component which is cooperable with the parallel surfaces of the window well, the foundation of the building, and the lower edge of the siding or sheathing of the building to secure the base member in position, the base member having parallel inclined inner sidewalls for receipt of a protective cover securable to the window well foundation.

Abstract: A ball latch mechanism including an annular cage concentrically located between a bearing member and a trigger. The cage includes a slot and a latch ball located in the slot in contacting relation with the trigger. The latch ball is radially movable between a first position in which the ball protrudes from the slot to interfere with movement of the bearing member and a second position wherein the ball is retracted into the trigger. Each slot is circumferentially elongated in relation to the ball such that, upon rotation of the trigger from a latch position to an unlatched position, the ball rolls circumferentially along the cylindrical surface within the slot. A biasing means may be used to urge the ball toward a preferred starting location.

Abstract: A release and arming mechanism for an ordnance device having an arming block, a pair of opposed jaws pivotally mounted to the arming block, and a solenoid that, when energized, holds the jaws in a closed position around an arming wire. A release lanyard connectable to the ordnance device is clipped to the jaws in such a manner as to hold the jaws in the closed position until such time as the ordnance device is launched. A spring may be placed between the jaws below their pivot points to force the jaws open upon disconnection of the release lanyard.
