Abstract: A machine part (12) is guided along a defined movement path (28) over a workpiece surface (23). The machine part (12) is held at a defined distance (50) from the workpiece surface (23) during this movement. For that purpose, a distance sensor (14) is provided that runs ahead of the machine part (12) with a defined lead (18). A plurality of distance values between the distance sensor (14) and the workpiece surface (23) are determined. A plurality of control values for adjusting the defined distance (50) are determined as a function of the distance values. The defined distance (50) is repeatedly adjusted by means of the control values. In accordance with one aspect of the invention, the distance values along the movement path (28) are determined by means of a first grid spacing (46). The control values are determined along the movement path (28) with a second grid spacing (44). The first and the second grid spacings (46, 44) are different.

Abstract: A machine part is guided along a defined movement path over a workpiece surface. The machine part is held at a defined distance from the workpiece surface during this movement. For that purpose, at least one distance sensor is provided that runs ahead of the machine part with a defined lead. A plurality of distance values indicative of a distance between the distance sensor and the workpiece surface are determined along the movement path. A plurality of control values are determined as a function of the distance values. The defined distance is repeatedly adjusted by means of the control values. In accordance with a first aspect, the distance values are determined at measurement points distributed with a first grid spacing along the movement path, while the control values are determined for actuating points distributed with a second grid spacing along the movement path, the first and the second grid spacings being different.

Abstract: Systems and methods are disclosed for focusing a beam for an interaction with a film deposited on a substrate wherein the focused beam defines a short axis and a long axis. In one aspect, the system may include a detecting system to analyze light reflected from the film on an image plane to determine whether the beam is focused in the short axis at the film. In still another aspect, a system may be provided for positioning a film (having an imperfect, non-planar surface) for interaction with a shaped line beam.

Abstract: A control unit for a machine tool or a coordinate measuring apparatus includes a control console having at least one operator-controlled element and a display screen. The operator-controlled element and the display screen are connected to a computer of the machine tool or the coordinate measuring apparatus. A converter expands or compresses a display screen signal outputted by the computer so that the entire content of the display screen on the control console is filled out with the display screen content of the computer independently of the image resolution of the display screen signal.

Abstract: In a coordinate measurement device with a base frame, a measurement table supported at the latter for holding an object to be measured, a sensing device for sensing the surface of this object, and with a positioning device for moving the sensing device in three spatial axes over the measurement table, which positioning device is mounted at the base frame and carries the sensing device, the positioning device has a first slide which is guided at the base frame in a first direction and which is movable on one side of the measurement table toward and away from the latter and on which a second slide is movable in a second direction vertical to the first direction, this second slide being provided at its end area remote of the measurement table (considered in its movement direction) with a supporting portion which projects lateral to the measurement table and at which there is arranged a stirrup arm which projects over the measurement table in a direction vertical to a principal work plane of the measurement table

Abstract: A mounting element (12, 12a, 12b) for securing components, in particular profile bars, and a cap (14, 14a, 14b) for covering the mounting element (12, 12a, 12b) are provided. Indentations (31, 39) are provided in lateral ribs (22, 36) of the mounting element (12, 12a, 12b) and/or of the cap (14, 14a, 14b). This makes the grip better and/or facilitates aligning the mounting element (12, 12a, 12b) and/or the cap (14, 14a, 14b).

Abstract: A device (10, 10′, 50) for furnishing material (12) to work stations is proposed. The device (10, 10′, 50) has at least one reservoir, embodied as a chute (14, 14′, 54), for the material (12). A discharge point (16, 16′, 56) having a gripper tongue (18, 18′, 58) adjoins the chute (14, 14′, 54). The chute (14, 14′, 54) and the discharge point (16, 16′, 56) are embodied as parts separably connected to one another. The discharge point (16, 16′, 56) can be disposed on one of the two face ends (36, 40, 76, 110) of the at least one chute (14, 14′, 54). By means of this arrangement, it is possible with only a few different parts to achieve great versatility in terms of the storage volume of the device (10, 10′, 50).

Abstract: A section rod is a component of a protective fence and serves for fastening a protective screen. A U-shaped receptacle, where the protective screen can be secured, is provided in the section rod. For this purpose, the receptacle has an internal width that is at least in part somewhat less than a thickness of the protective screen. An increased securing action can be achieved through additional sawtooth-shaped elevations. The section rod allows the protective screen to be mounted in a simple and reliable manner without additional fastening or securing parts.

Abstract: An angle bracket for joining two section bars has a relatively great stability, especially for use for partitions and safety walls. This stability is achieved by supporting walls that join the two legs of an angle bracket to one another and have an outwardly rounded outside contour. This design is relatively simple and inexpensive to implement and allows these angle brackets to be compatible with known designs.
