Abstract: A device for stabilizing a workpiece, in particular a thin-walled workpiece mounted in a machine tool, comprises at least one base; and a plurality of stabilizing elements. The stabilizing elements protrude away from one surface of the base, wherein the stabilizing element comprises a cylinder and a rod arranged therein and the rod can be driven hydraulically to move in the axial direction of the stabilizing element such that the rod of at least two of the stabilizing elements can be brought into contact with one surface of the workpiece.

Abstract: The machine tool has a machine bed having a first horizontal linear guide and a second horizontal linear guide arranged at right angles to the first linear guide. On the first linear guide is arranged, in an axially displaceable manner, a workpiece clamping fixture, which is swivelable about a swivel axis oriented parallel to the second linear guide and is rotatable about a rotation axis oriented at right angles to the swivel axis. On the second linear guide a toque motor driven swivel arm is axially displaceable, the swivel axis of which is arranged parallel to the first linear guide and which on its free end bears a tool spindle, the axis of which is oriented parallel to the first linear guide.

Abstract: The chain magazine for holding tool'(5) for machine tool'includes a continuous chain (1) which has chain links (2) each with at least one tool holder (2a, 2b) and with which at least one sprocket (6, 7) meshes and a guide device (9-12) which has a guide element (12) that can be moved back and forth between a first and a second position, by means of which a tool holder (2a, 2b) of a chain link (2) can be turned in and turned out.

Abstract: The brushing device contains a bundle of fiber rods (1), which are arranged parallel to one another, and a protective sleeve (2), which encloses the fiber rods. Once fiber rods (1) have become worn, the protective sleeve (2) is able to be axially adjusted, so that the free ends of the fiber rods (1) protrude beyond the protective sleeve (2) by a desired amount. A first component (4) connected to the fiber rods (1) and a further, second component (8) connected to the protective sleeve (2) are detachably connected to one another, in a non-positively locking manner, by a clamping mechanism (3, 5, 11).

Abstract: The machine tool has a machine bed (10) having a first horizontal linear guide (1) and a second horizontal linear guide (2) arranged at right angles to the first linear guide (1). On the first linear guide (1) is arranged, in an axially displaceable manner, a workpiece clamping fixture (3), which is swivelable about a swivel axis (4) oriented parallel to the second linear guide (2) and is rotatable about a rotation axis (5) oriented at right angles to the swivel axis (4). On the second linear guide (2) a toque motor driven swivel arm (6) is axially displaceable, the swivel axis (7) of which is arranged parallel to the first linear guide (1) and which on its free end bears a tool spindle (8), the axis (9) of which is oriented parallel to the first linear guide (1).

Abstract: A breast pump for collecting breast milk having a funnel intended to receive the breast, a housing and a device for producing a negative pressure. The funnel consists of a flexible material and extends into the housing. The device for producing a negative pressure has at least one body that is movable over a portion of the length of the funnel while compressing the funnel.

Abstract: Transparent content and opaque content that is contained within a document is treated differently for printing. The transparent content within a document is rasterized and stored in a system-managed bitmap before printing. While rasterization is effective for maintaining visual fidelity of transparent content it can lead to large spool files and poor performance if excessively performed. In order to help optimize the performance of output devices, the transparent content within the document is rasterized and the opaque vector content within the document is drawn into a metafile before printing. The metafile is replayed onto the printer and into the bitmap such that the opaque content can be blended with the rasterized transparent layers that are contained within the bitmap. The bitmap is then drawn on the printer.

Abstract: The machine tool is provided for working ring-shaped workpieces (1), in particular one-piece turbine wheels, so-called “bladed rings”. It has a rotatable chucking device (2) for a workpiece (1). Said chucking device is mounted on a carrying part (4), which in turn is supported by a supporting component (5). In order to keep the dimension (14) of the length by which the carrying part (4) projects beyond the workpiece (1) on the side facing the supporting component (5), as low as possible, the carrying part (4) protrudes into the chucking device (2) to such an extent that it projects at least through the boundary surface (7) of the workpiece (1) facing the supporting component (5). A saving of space is achieved in this way and, therefore, enhanced accessibility is obtained for the tool to the side of the workpiece (1) facing the supporting component (5).

Abstract: Conventional positioning devices in which a body is displaceable in a plane and rotatable by three drives have the drawback that at least one of the drives is displaced together with the body, whereby these apparatus are relatively heavy and sluggish. In the case of the positioning device according to the invention, three straight guide elements, arranged radially, are rigidly connected to the body. Each guide element is accepted in a linear bearing in a longitudinally displaceable way, and each linear bearing is disposed on a separate rotor in a way pivotable about a pivot axis directed perpendicular to the plane. Through independent displacement of the linear bearings on a common circular path, the body can be shifted and rotated as desired in a region. This construction has the advantage that it is built simply and that it is able to execute quick and precise positioning movements in particular owing to small masses in motion.
