Abstract: A suction device for removing X-ray sheet films from a dispenser magazine of an X-ray sheet film cassette loading and unloading device has at least two suction elements and is displaceable so that for withdrawing an X-ray sheet film from a dispenser magazine it is movable to a withdrawal position, the withdrawn X-ray sheet film is taken from the suction device by a transporting roller pair, and a control device controls the transporting movement of the suction device and a tranasporting roller pair as well as the opening and closing of the dispenser magazine. The suction elements are arranged on a suction element axle which is movable in two displaceable suction element axial bearings, a lifting basket is articulately connected to a base plate by four hinge members, and a drive element is arranged on the base plate and moves the lifting basket and the suction element axle.

Abstract: A supply magazine has a drawer-shaped, upwardly open box for introducing a sheet film stack in a light-tight envelope and for withdrawing individual sheet films after removal of the envelope, a cover part movable relative to the box, a unit for winding the envelope in a closed condition of the magazine. The cover part is formed as a flat parallelepiped which is open at its front small side and such that the box which is open at its upper side can be moved in and out of the cover part, a locking mechanism operates for locking the cover part and the box when the box is moved in. A lockable and swingable flap cover is provided on a flat side of the cover part corresponding to the upper side of the box so that when the box is moved in the cover part a sheet film stack can be inserted in the box through the flap cover.

Abstract: A supply magazine for insertion in an arrangement for removing individual sheet films, for example X-ray sheet films, arranged in a stack in a light-tight wrapping, comprises a cover, a box which is at least partially open and is closable by the cover, and being formed for accommodating a stack located in a wrapping, a winding device provided with a winding shaft which is driven from outside and formed for suspending and winding a winding flap of the wrapping together with the latter after closing of the box, and an indicating device including a movable sensing member which abuts with spring biasing against the winding shaft in the region of the winding flap, an observation opening formed in a part of the box which supports the winding shaft and arranged so that the sensing member is visible through the observation window, and a light sealing provided between the winding shaft and the observation window.

Abstract: A diaprojector for framed diapositives accommodated in at least two different magazines has two tracks each for a respective one of the magazines having smaller and greater diapositive compartment widths, a drive for gradually transporting each of the magazines by a distance corresponding to the width of the diapositive compartments, a sliding element having a width suitable for exchanging the diapositives in one of the magazines, and a rider having a width suitable for exchanging of the diapositives in the other magazine and displaceable on the sliding element between two positions in which either the sliding element or the rider is available for acting upon the respective magazine, and a sensing device operative for blocking the operation of the projector, when the position of the rider does not correspond to the magazine in which the diapositives must be exchanged.
