Abstract: Thus a lifter table de-stacker 1 is provided comprising a lifter table 3 with a stack 10 holding device 4 above the lifter table. The holding unit positions the stack by motorized guiding elements 14 and 15. A de-stacking unit and in particular a suction unit is provided which can be adjusted in its position above the stack 10 by a motor as well. The lifter table de-stacker with the motorized adjustability of the guiding elements and the de-stacker provides for a very fast adaptation to different sheet metal blank sizes. Such a lifter table de-stacker is preferably provided for feeding sheet metal blanks into a rounding apparatus which is feeding rounded blank container bodies into a resistance seam welding machine for container bodies.

Abstract: A stereomicroscope system (1) having an incident illumination device is disclosed. The stereomicroscope system (1) comprises a base (13) on which a focusing column (11) is secured. Mounted shiftably on the focusing column (11) is a focusing arm (5) which has an opening that serves to receive a stereomicroscope (3). The stereomicroscope (3) defines a device axis (20) that is perpendicular to the base (13). Multiple light-emitting diodes (30) are arranged in the focusing arm (5) around the receiving opening (5c). Multiple light-emitting diodes (31) are likewise arranged along the focusing arm (5) between the focusing column (11) and the receiving opening (5c).

Abstract: A stereomicroscope having a carrier (12) bearing a microscope body (4) displaceable obliquely relative to a displacement direction of a focus-adjusting mechanism (9). A binocular beam splitter (2a) is used to combine two stereoscopic observation beam paths (3a, 3b) into a common beam path (3c), wherein the axes of the two observation beam paths (3a, 3b) entering into the binocular beam splitter (2a) and the axis of the beam path (3c) emerging from the binocular beam splitter (2a) are parallel to each other, and the axis of the emerging beam path (3c) is disposed at displacement (Vs) from a symmetry axis of the two entering observation beam paths (3a, 3b). Displacement of the carrier being able to compensate for displacement (Vs). A switching device (5) is provided that can be activated to bring lenses (6, 7) over an object (8) parfocally and parcentrically.

Abstract: A stereomicroscope with a binocular tube (1); with a microscope body (4); with a microscope holder (14) that is connected to a focus-adjusting mechanism (9), the focus-adjusting mechanism (9) in turn being fastened to a stand (13); with a carrier (12) bearing the microscope body (4) and being displaceable obliquely relative to the displacement direction of the focus-adjusting mechanism (9); with a binocular beam splitter (2a) used to combine the two stereoscopic observation beam paths (3a, 3b) into a common beam path (3c), wherein the axes of the two observation beam paths (3a, 3b) entering into the binocular beam splitter (2a) and the axis of the beam path (3c) emerging from the binocular beam splitter (2a) are parallel to each other, and the axis of the emerging beam path (3c) is disposed at distance (Vs) from the symmetry axis of the two entering observation beam paths (3a, 3b) it being possible to compensate for said displacement (Vs) by the displacement range of the carrier; (12) with a switching device

Abstract: A method of calibrating the magnification of a stereomicroscope having variable magnification comprises the steps of (A) positioning an object reference measure (10) with a known scaling in an object plane (8) of the stereomicroscope; (B) providing an eyepiece reference measure (6a) of known scaling in an intermediate image plane (7) of the stereomicroscope; (C) varying the magnification of the stereomicroscope using a zoom system (4) thereof so that an image of the object reference measure (10) is brought into optical alignment (coincidence) with the eyepiece reference measure (6a) in the intermediate image plane (7) in order to determine a zoom position of the zoom system (4) corresponding to this alignment; (D) determining an actual magnification of the stereomicroscope in the zoom position on the basis of a lateral magnification defined by the scalings of the object reference measure (10) and eyepiece reference measure (6a) which have been brought into alignment; (E) determining a nominal magnification of

Abstract: The retaining element is extended from a carousel disk in the plane of the disk and holds a bottle to be retained by the carousel essentially only at one point (T). The retaining element can be provided with an easily exchangeable finger part thus permitting quick and easy adaptation to different bottle sizes. As the retaining element swings out against the bottle without touching it during the swinging action, there is no risk of damage to the bottle.
