Abstract: A data processing system for processing object data of a plurality of standard instances (101), where object identification data (100) and user data (110) in the object data database (20) can be stored and retrieved separately from each other so that no relationship between the object identification data (100) and the user data (110) can be derived from the stored data records alone, where at least one input device is provided which, after input of an allocated security code for the standard instance, permits access to the object identification data (100) of the assigned standard instance and to the associated user data (110), and the security code or a part thereof remains with the standard instance (101), with the recovery instance and if necessary with further instances (50, 60) determined by the standard instance.

Abstract: Binoculars having a central device for focusing and diopter adjustment wherein the diopter adjusting wheel is integrated into the face of the focusing drive wheel, whereby the focusing and the diopter adjustment can be performed independently of each other.

Abstract: A binocular telescope having a double-jointed bridge and a central joint focusing means for focusing and diopter adjustment with a bipartite bridge, the two bridge members being connected via a center clutch shaft.

Abstract: A central focussing device for internal focussing in binoculars, wherein a focussing wheel engages a displaceable bridge via a threaded spindle and the objectives are connected to the displaceable bridge via driving shafts for the purpose of focussing, a diopter adjustment wheel engages one of the driving shafts with screw drive via a driving toothed wheel, an intermediate toothed wheel and a driven toothed wheel in order to vary the position of an objective for diopter adjustment, the intermediate toothed wheel being directed through the bridge or beside and past it and being of a height such that the driven toothed wheel engages the intermediate toothed wheel over the entire range of stroke of focussing.
