Abstract: An apparatus provided with wedge-shaped elements is proposed for the precision positioning of objects 37 to be measured or machined. A wedge-shaped translational body 32 is carried by two bearing wedges 24, 26. In accordance with the invention the wedges can be independently translated in the x direction.

A high precision is thus obtained, because fewer errors due to non-infinite stiffnesses and error motions are accumulated. A laser measuring apparatus 74, 38, 40 is used for measuring and adjusting the position of the object carrier 35.

Abstract: Pull-out shelf for mounting on rack uprights, comprising two brackets (4) projecting from the uprights. Each bracket bears a pullout rail (7) and a shelf plane (8-12) or equivalent, supported by the rails, for articles which are to be placed on the shelf. The shelf comprises at least one releasable locking member which, when an associated operating member (18) is acuated manaully, releases the pull-out rails (7), so that these can be pulled out and pushed in, and, in the unactuated state, locks the rails relative to the brackets (4). The locking members are adapted so as, when the operating member is unactuated, to lock the rails under the action of a spring force, the manual actuation of the operating member taking place counter to the action of this spring force. Releasing the operating member then results in instantaneous locking of the rails and thus the shelf in the current position, which allows stepless locking of the shelf in optional positions between an inner and an outer end position.
