    Abstract: A self-opening and self-closing device enabling entry into a controlled access area includes a gate with two laterally retractable panels that may be opened by inserting a ticket or access card into a control mechanism. Each of the panels is controlled by a respective motor operated by the control mechanism. Each panel is secured to at least two runner members that are each operated by a roller secured to a link arm. The link arms are rotationally interconnected and rotated by the respective motor. Simultaneous rotation of the arms in opposite directions moves the two panels together (or apart) and thus closes (or opens) the entry device by moving each panel into a position in which it is locked by the respective arm in the horizontal position.

    Abstract: A time delay release mechanism has a brake actuator including an actuation member movable between engaged and released positions. The actuation member, when in the engaged position, operatively engages a fire barrier for preventing closure thereof. The actuation member, when in the released position, is operatively disengaged from the fire barrier such that the release mechanism does not prevent closure thereof. The brake actuator includes an actuation driver which, when receiving electrical power, moves the actuation member to the released position. A timer, when receiving electrical power or when power thereto is interrupted for a duration less than a predetermined time period, disengages from the actuation member allowing the actuation driver, when power thereto is initially interrupted, to move the actuation member to the engaged position. The timer engages the actuation member, when power to the timer is interrupted for a duration greater than the predetermined time period, to move the actuation member to the released position thereby overriding the actuation driver to allow closure of the fire barrier. The timer disengages from the actuation member when power to the timer is restored and the actuation driver retains the actuation member in the released position when power to the actuation driver is restored, thereby automatically resetting the brake actuator and timer.

    Abstract: The invention relates to a system for opening and closing a window aperture, the system comprising: a moveable window panel; a pulley assembly coupled to the moveable window panel; a counterweight; and a pulley actuation mechanism. The moveable panel is heavier than the counterweight, the latter being attached to a first lateral side of the moveable panel via a first part of the pulley assembly. The pulley actuation mechanism is attached to an opposite lateral side of the moveable panel via a second part of the pulley assembly. The pulley actuation mechanism is switchable between energised and non-energised states based on one or more trigger events, between a closing mode whereby the pulley actuation mechanism retracts the second part of the pulley assembly thus imparting an additional closing force to the moveable panel sufficient to raise the moveable panel; and an opening mode whereby the pulley actuation mechanism is non-energised such that a passive opening force is imparted to the moveable panel by virtue of its weight to lower the moveable panel. A system for controlling a window system based on aircraft detection is also disclosed.
