Abstract: The invention relates to a cot comprising four height-adjustable side parts (3). In order to enable the side parts to be vertically adjusted without applying a force, a plurality of controllable motors (4) is provided on the bed (1) for lowering and raising each side part (3), such that the height can be continuously adjusted. An electric motor or a hydraulic motor is used as the motor (4), and a vertical hollow post (5) is provided on at least one of the corners of the bed (1), the motor (4) being arranged in the cavity (10) of said post with a spindle-nut drive. The hollow post (5) is embodied as an extruded profiled element (38) with different functional moulded elements.

Abstract: A system and method that communicates with archive systems that use various query languages. The system includes an interpreter, which receives an inquiry in a non-archive-system-specific form, converts the inquiry into an archive-system-specific form or allocates it to an archive-system-specific form and executes the inquiry in a selected archive system. Processing of the search results, management of the interface with the archive system and the pertinent administrative work is undertaken by the interpreter. The knowledge required of a user regarding the individual archive systems is reduced to a minimum. The various interfaces of the interpreter make it possible to use source code for different archive systems with few modifications.
