Abstract: The present disclosure relates to a blind nut, a fastening arrangement and further to a method of fastening. The blind nut includes a cylindrical outer surface portion provided with one or more sealing elements. The sealing elements of the blind nut may seal against a cylindrical inner surface of a nut space inside which the blind nut is configured to penetrate when being tightened.

Abstract: An acetabular cup excise device includes a cup excising portion, an elongated handle shaft extending along a longitudinal axis from the cup excising portion, and a positioning assembly operably coupled to the handle shaft. The positioning assembly is configured to allow rotation of a handle lever, about the longitudinal axis, to position the handle lever along at least a first radial axis perpendicular to the longitudinal axis and a second radial axis perpendicular to the longitudinal axis.

Abstract: A fixture and cutter tool is described. The fixtures includes features that enable a work piece to be easily mounted and removed by a rotation motion of the work piece onto the top of the fixture. The system includes the fixture and a cutter tool to prepare the work piece for use with the fixture.

Abstract: A clamping unit, in particular for use in a machining center, or a turning or milling center, wherein the clamping unit comprises an external housing (12), preferably having a cylindrical basic design, an internal housing (15) accommodated in the external housing (12), and an internal cylinder (11) that is retained in the internal housing (15) such that it can be displaced in a vertical adjustment direction A when in the operating state, which is designed for transferring a pressure or tensile force for clamping purposes, wherein the internal housing (15) is supported in the external housing (12) by means of springs (13, 14), and is supported with respect to the external housing (12) such that it can be displaced in the adjustment direction A, and thus forms a spring force storage unit (21), and wherein an electric motor (16) is disposed inside the clamping unit, integrated therein, preferably encompassed by the external housing (12), furthermore, preferably accommodated inside the internal housing (15), in o

Abstract: A bench vice includes a fixed vice body, a movable vice body, a screw rod, a screw nut, a quick-action mechanism, and an operating handle. The quick-action mechanism controls the screw rod and screw nut to engage or disengage so as to move slowly or quickly. The operating handle operates the quick-action mechanism. The movable vice body is assembled with the screw rod into an assembly, and both the quick-action mechanism and the operating handle are arranged on the front end of the fixed vice body. Since the quick-action mechanism and the operating handle are arranged on the front end of the fixed vice body, the operator can operate more conveniently, and thereby the working efficiency is improved.

Abstract: A work holding device includes a first jaw piece having an elongated first connection member for connecting the work holding device to a support. The first connection member defines a first passage. A second jaw piece has an elongated second connection member positionable within the first passage. The second connection member defines a second passage in communication with the first passage. A spindle assembly movably couples the second jaw piece to the first jaw piece. The spindle assembly is configured to move the second jaw piece with respect to the first jaw piece to create a clamping pressure when an object is placed between the first jaw piece and the second jaw piece.

Abstract: An apparatus for cutting workpieces adapted to engage the workpiece in at least four points of surface engagement. The apparatus has a clamping mechanism designed to be fastened to the workpiece. The clamping mechanism has a tool unit attached which includes adjustment means for displacing the tool unit relative to the clamping mechanism towards or away from the workpiece. The clamping mechanism has a frame element and arms extending from the clamping mechanism. Each of the four arms includes a bearing wheel. Each of the wheels may be used to engage a workpiece to retain its position while it is being cut.

Abstract: The subject of the invention is glazing which incorporates at least one electrically controllable system having variable optical and/or energy properties, especially in the form of a system comprising one or more reversible-insertion materials of the electrochromic-system type, in the form of an optical-valve or viologen-based system or in the form of a liquid-crystal or cholesteric-gel system. This glazing also includes at least one means for adjusting the optical appearance conferred on the said glazing by the said system, these means comprising at least one coating having antireflection properties in the visible.

Abstract: A vise has a housing block formed with a guide defining a longitudinal direction, a fixed jaw secured to the block, a movable jaw displaceable in the direction in the guide relative to the fixed jaw, and a spindle extending in the direction between the jaws along a spindle axis. A support at the fixed jaw has a formation fitting with the fixed jaw and fixing the support and fixed jaw together against relative axial displacement while permitting limited relative pivoting about a fixed-jaw axis generally perpendicular to the spindle axis.
