A steam sterilizer having a door movable relative to an opening between a first open position and a second closed position. A plurality of spaced-apart roller assemblies are aligned along edges of the door to align the door relative to the opening as the door moves between the open and closed position. Each of the roller assemblies are comprised of a cylindrical roller having an outer annual recess extending along the periphery thereof. The recess is dimensioned to receive a lateral edge of the door. The roller is mounted on a shaft and is movable against a biasing force axially along the axis of the shaft.

A sliding window for a building includes a stationary frame, an opening leaf, a motorized drive device, a fittings system, and a locking control device. The motorized drive device includes an electromechanical actuator, a flexible element, and a drive arm. The flexible element drives movement of the opening leaf with respect to the stationary frame when the actuator is electrically activated. The arm is connected both to a frame of the opening leaf and to the flexible element. The locking control device collaborates with a lock of the fittings system and is actuated by the flexible element when the actuator is electrically activated. The drive arm supports the locking control device. The fittings system also includes an errorproofing system. The locking control device actuates the lock following activation of the errorproofing system and when the actuator is electrically activated.

A retention mechanism for a pair of bi-parting doors of a transit vehicle includes a first track connected to a first door of the pair; a second track connected to a second door of the pair; a first retention assembly connected to the transit vehicle and configured to retain the first track in the closed position; a second retention assembly connected to the transit vehicle and configured to retain the second track in the closed position; a first engagement member connected to the second track, the first engagement member being configured to engage the first retention assembly to cause the first retention assembly to move to retain the first track in the closed position when the second track is in the closed position; and a second engagement member connected to the first track, the second engagement member being configured to engage the second retention assembly to cause the second retention assembly to move to retain the second track in the closed position when the first track is in the closed position.

A diagnostic apparatus includes a drive mechanism configured to open or close a door panel, and includes a fastening mechanism configured to fasten the door panel to the drive mechanism. The diagnostic apparatus includes circuitry configured to acquire first data related to an operation of a door of a train carriage, during at least one of an opening operation or a closing operation of the door, and to diagnose an abnormality in the fastening mechanism based on the acquired first data.
