    摘要: A cutting insert including a flank face, a rake face, and a cutting edge at the intersection of the flank and rake faces that is useful in the chip forming machining of workpiece materials is disclosed. The cutting insert comprises a cermet comprising at least one hard component and about 2 wt % to 19 wt % Co--Ni--FE-binder. The Co--Ni--FE-binder is unique in that even when subjected to plastic deformation, the binder substantially maintains its face centered cubic (fcc) crystal structure and avoids stress and/or strain induced transformations.

    摘要: A tensioner for the chain or the belt of an internal combustion engine, for example of the camshaft drive, includes a cylindrical tensioner housing (2) with a piston (1) loaded by a compression spring (13) arranged therein, the tensioner housing and the piston being axially displaceable relative to each other. The displaceable element which is displaceable relative to the fixed element in chain tensioning direction, is surrounded by a first stop ring which limits its backward movement. According to the invention, the first stop ring is configured as a retaining clip (15) whose arms engage into a locking groove (16) of the tensioner housing (2) under radial pre-stress and, upon a displacement thereof, can come to bear axially against a stop surface of the receiving housing (3).

    摘要: The invention concerns a hydraulic play-compensation element including a groove (11) in the housing (1) to be located in such a way that, whatever the position of the plunger (2), a length (19) of the plunger is always supported by the cylinder wall above the groove and the securing ring (12) is centered radially around the plunger by means of a recess (14) in the plunger, the recess having a ramp at least at its lower end. The invention thus avoids weakening of the material in the upper part of the plunger.

    摘要: The invention relates to a ruthenium complex having the formulaRu.sup.2+ L.sub.1 L.sub.2 L.sub.3 Iwherein L.sub.1, L.sub.2 and L.sub.3 are the same or different are equal to a bi- or polycyclic ligand with at least two nitrogen-containing heterocycles, whereby at least one of these ligands is substituted with at least one group conferring water-solubility, and whereby at least one of these ligands is substituted, optionally via a spacer group, with at least one reactive group, and whereby the ligands L.sub.1, L.sub.2 and L.sub.3 are attached to the ruthenium via nitrogen atoms.The invention is further related to such ruthenium complexes having coupled thereto an immunologically active material, for example, antigens, haptens or antibodies and to the use of said ruthenium complexes in fluorescence spectroscopy. Specific ligands L.sub.1, L.sub.2 and L.sub.3 which are useful in the ruthenium complexes of the invention are, e.g., 2,2'-bipyridine, 1,10-phenanthroline benzbathophenanthroline or bathophenanthroline groups. Groups which are useful for conferring water-solubility on said ligand are, e.g. sulfonic acid groups which are preferably present in the form of their salts. Useful spacer groups are e.g. an alkylene groupcontaining 1-8 carbon atoms and which is optionally substituted with --SO.sub.2 --NH--, --S--, --O--, --COO-- or --CO--NH-- groups. Useful reactive groups to which the immunologically active material is coupled, are e.g. --COOH, --I, --NH.sub.2, --NCS or --SO.sub.2 Hal groups. The ruthenium complexes according to the present invention can be detected with great sensitivity by fluorescence spectroscopy and are thus useful in fluorescense immunoassays.
