Abstract: An aircraft is equipped with an auxiliary access control barrier (AACB) to prevent access to an area of the aircraft. The AACB includes laterally extendable door panels that are slidably attached to each other to vary a width of the AACB, a hinge by which the door panels are pivotably attached to the aircraft, such that the door panels are pivotable between a deployed position, in which the door panels are positioned across the opening to prevent passage through the opening and in which the AACB has a first width, and a stowed position, in which the door panels are positioned to allow passage through the opening and in which the AACB has a second width, and one or more locks to prevent relative motion between the door panels to fix the width of the AACB and/or to secure the AACB within the opening in the bulkhead.

Abstract: An automated banking machine is operated responsive to data bearing records. The machine operates using data read from user cards and causes funds to be transferred. The machine includes a housing, a card reader operative to read indicia on user cards corresponding to financial accounts, a display, a cash dispenser, a secure enclosure including a chest and a door supported on hinges. A fascia is supported by the door through planar linkages and movable from a position adjacent the door to a position away from the door. A side extension is supported by the door through a planar linkage and movable from a position adjacent the hinges to a position spaced apart from the hinges. A connecting linkage operatively connects at least one fascia linkage with the side extension linkage.

Abstract: An aircraft security system comprises a transparent bullet-proof security chamber interposed between the pilot area and the passenger area, and providing the only means of passage to the pilot area. The security chamber has a cockpit door to the cockpit area and passenger door to the passenger area. The passenger door must be closed when the cockpit door is open and vice versa. A third, or entry door, may be used to facilitate boarding the aircraft. All doors are closed and locked when sensors indicate unauthorized entry of a passenger into the security chamber.

Abstract: A device for opening and closing a hatchway on a combat vehicle, especially a tank, by a hatch. The hatch comprises two components, one above the other. The upper component slides back and forth across and above the hatchway. The lower component descends tight into the hatchway. The object is to simplify the generic device to the extent that it can be operated from inside the vehicle. An operations-control rack extends along the upper component in the direction it slides back and forth in. The rack is engaged by a pinion. The pinion is part of a mechanism mounted on the vehicle and controlled from inside the vehicle. A cam track is fastened tight to the rack. A control pin rests against the cam track. The cam track operates by way of the control pin in conjunction with at least one mechanism that locks the upper component in position. The upper component is attached to the rack by a clutch.

Abstract: A security box assembly has a body portion and a cover portion. The cover portion has a top wall with hook and loop type fastener sheets for adhering the box to the undersurface of a table or counter, and has depending walls defining a downwardly open hollow interior. The body portion has a bottom wall with upstanding walls defining an upwardly open hollow interior. The body portion is moveable to and from a closed, locked position against the underside of the cover portion, in which portion the upwardly and downwardly facing openings are in registration. A parallelogram linkage system consisting of pairs of parallel pivoted links on each side of the assembly connect the side walls of the body portion with side walls of the cover portion thereby enabling the body portion to move downwardly and forwardly from the closed, locked position to an open position providing ready access to the interior of the body portion.

Abstract: A valuables safe incorporates a money slot that is both inaccessible and out of sight during periods when it is not desired to use the money slot, for example during off-hours in a business. The money slot is quickly made both accessible and visible by opening the safe and repositioning one element.

Abstract: A safe having a valuables chamber with an access opening with inwardly extending ledges for placement of a plate-shaped separate steel door thereon, and a set of grooves formed on opposing walls retaining the door therein, the width of the grooves being a distance slightly more than the thickness of the door, with one groove being substantially greater than the depth of the other, with one edge of the door being inserted on a slight angle into the deeper groove while the other edge is pivoted toward the ledge, the door then being laterally displaced until the latter edge is in abutment with the seat of the shallower groove. A lock assembly on the reverse side of the door has the latch bolt engaging a detent in a metal bar for prevention of lateral movement with reinforcing bolts adjacent the lock bolt preventing force on the lock mechanism in the event of forceful intrusion attempts.
