Abstract: A modular heating system for large vehicles. At least one elongated heating element module is suitable for horizontal mounting along an interior wall and near the floor of the vehicle. The heating element module includes a convector including at least one essentially longitudinally extending pipe arranged to conduct a heating medium. The pipe is provided with a plurality of mutually spaced fins transversely mounted thereto. The system further includes at least one blower module including at least one fan. The blower module is selectively attachable to the heating element module at an arbitrary position along the extension thereof adjacent to the fins and further arranged to be selectively operable to produce a forced airflow through the plurality of fins in a direction from a side of the convector intended to be mounted facing upwards towards a side thereof intended to be mounted facing downwards.

Abstract: A lockable cassette (8) having a lid (10) is closed and locked when removed from a cassette casing but is released and unlocked when inserted into the casing by virtue of the actuation of an element (19, 25) which functions to move a lock bolt (18) from a lid-latching starting position to a lid release position. The element includes an electric relay (19) and a two-arm lever (25). A core (23) of the relay is attached to one arm (31) of the two-arm lever and is actuable by a first pressure spring (21), wherein the other arm (32) of the lever forms abutment surfaces or stop surfaces for the lock bolt in its lid latching position when the relay is inactive.

Abstract: An arrangement for feeding sheets from a bundle of sheets includes a wheel, roller or belt which, in operation, is located at one end of the bundle and which functions to feed-out the outermost sheets of the bundle, and a lifting mechanism for lifting the bundle in a direction towards the wheel. The lifting mechanism includes a post and a bundle-carrying plate which is movable up and down the post. The arrangement includes a spring element which functions to lock the plate to the post in a rest state and has a free-end which is fitted to the post and defines, with the longitudinal axis of the post, an angle other than 90.degree. and whose remaining end is attached to the plate and movable perpendicular to the post. The arrangement also includes an actuator which is fitted to the post close to the spring element and which is releasably attached mechanically to a drive mechanism for moving the plate relative to the post.
