Abstract: The present invention relates to a binary single phase titanium-zirconium alloy suitable for the production of surgical implants. The alloy includes a zirconium content of less than 25% but more than 5% by weight, and 0.1% to 0.3% by weight of oxygen as a strength enhancing additive, and not more than 1% by weight of other strength enhancing additives and technical impurities.

Abstract: An osteogenic implant with improved osteointegration properties, this implant being made of titanium metal or a titanium-based alloy and being suitable for implantation in bones, said implant having a roughened surface, which in the hydroxylated state has been at least partially covered with a compound which comprises in the molecule at least two groups which are, independently of one another, a primary amino group, a secondary amino group, a carboxyl group, an amide group, a phosphano group and/or hydroxyl, or with a mixture of such compounds.

Abstract: An osteogenic implant with improved osteointegration properties. In one embodiment said implant consists of titanium or a titanium base alloy and has an at least partially roughed-up surface. Said surface, in the hydroxylated state, is at least partially coated with a polypeptide, namely a transforming growth factor (TGF) or a systemic hormone, or with a mixture of such compounds.

Abstract: Jewelry is produced employing alloys of Fe, Co, Ni, Pd, Pt, Au, as well as --in smaller quantities--Cu, in conjunction with Al, Ga, In, Si, these alloys displaying the feature of being crystallized in the cubic structure of the type B2 or C1, designations as used in structure reports. These alloys, which display very decorative colors not found with other metals, or anywhere else in nature, are--per se--very brittle and subject to spontaneous disintegration in reactive media. For this reason, these materials are very difficult to form and cannot be used for the intended purpose. Their properties can be decisively improved by impressing upon the alloys a grain size of less than 50 .mu.m by hot-forming or by sintering, for example, or by some other process, and by selecting the composition of the alloy with the intent to keep the quantity of the transition metal component A at a value not lower than stochiometric value. The jewelry items may consist of one of these alloys, fully or partially.

Abstract: The invention relates to an elongate plate for osteosynthesis. The plate comprises at least two screw holes and a respective hole-free longitudinal section separating each neighboring pair of the screw holes. A spacing, perpendicular to the longitudinal direction of the plate, between two mutually opposite surfaces of at least two sections containing the screw holes is greater than that between two mutually opposite surfaces of the hole-free sections. The plate exhibits at least in the region of the screw holes a bending resistance amount W=I/e along a plane extending substantially centrally of the plate in the longitudinal direction of the plate and intersecting substantially perpendicularly that surface of the plate which is intended to rest on a bone.
