Abstract: An automatic radio actuated mechanism for opening and closing panels, such as a garage door, makes use of an electric motor to rotate a specially constructed spiral drive screw and move a traveler along a track, the traveler being connected to the door to pull the door open or push the door shut. Included in the mechanism is a camming arrangement for precisely adjusting the full open and full closed positions by action of an electronic circuit which activates the motor. For reversing the operating direction of door movement in the event such movement should be obstructed, the motor housing is mounted in a manner allowing it when restrained to swing for a limited distance, one way or the other, thereby to actuate a switch in the electronic circuit for reversing movement of the door.

Abstract: A panic exit actuator and locking mechanism adapted particularly for mounting on a narrow stile door frame with the actuator spanning substantially the full door width and extending between the inner and outer narrow stile frame members, and wherein the lock mechanism is mounted in the outer narrow stile frame member and has a latch bolt supported for movement between latched and unlatched positions, the latch bolt being releasably retained in the latched position by deadlock means and being movable to an unlatched position in response to pressure applied in a door opening direction to a push bar that is movably supported on one or more linkage assemblies having an operating connection with actuating means operable to initially release the deadlock and thereafter move the latch bolt to the unlatched position.
