Abstract: A weighing device for the self-service registration of goods in stores contains a floor scale (2), which is disposed in an upwardly open standing container (3). The floor scale (2) has a suspension device (8) for at least one carrying container (11) which is removable from it. It is protected by the standing container (3) against accidental influences from outside, so that prolongations of the weighing procedure are prevented. As a result of the arrangement of the carrying container (11) on the floor balance (3), the departure of the customer with the weighed goods from the weighing area is speeded up. As the weighing receptacle in the standing container (3), a shopping container, for example a shopping cart (21), can also be used. For this purpose, the floor scale (50, 60) is in this case of U-shaped configuration in top view and is provided with bearing elements (52, 71) for the shopping container.

Abstract: In a carrier arrangement for the magnetic heads of a magnetic disk drive, the swiveling arms (10) carrying the magnetic heads are fastened onto a bearing sleeve (40) which in turn is pivoted by antifriction bearings (24,26) on a spindle (18) which can be firmly fixed in a bearing block.

Abstract: A device for centering a record disc with respect to a turntable, in which the disc is successively radially centered and axially positioned relative to the turntable, which device includes a centering shaft engageable with the disc to effect preliminary radial centering thereof, is additionally provided with further radial centering elements mounted to engage a disc after it has engaged the shaft and to undergo yieldable movement relative to the turntable in the axial direction of the disc under the influence of its engagement with the disc for effecting final radial centering of the disc, and a magnetic attracting unit operatively associated with the disc and the turntable for axially positioning the disc after it has been finally radially centered.
