Hydrogen purification membranes, hydrogen purification devices, and fuel processing and fuel cell systems that include hydrogen purification devices. The hydrogen purification membranes include a metal membrane, which is at least substantially comprised of palladium or a palladium alloy. In some embodiments, the membrane contains trace amounts of carbon, silicon, and/or oxygen. In some embodiments, the membranes form part of a hydrogen purification device that includes an enclosure containing a separation assembly, which is adapted to receive a mixed gas stream containing hydrogen gas and to produce a stream that contains pure or at least substantially pure hydrogen gas therefrom. In some embodiments, the membrane(s) and/or purification device forms a portion of a fuel processor, and in some embodiments, the membrane(s) and/or purification device forms a portion of a fuel processing or fuel cell system.

Implant in accordance with claim 2, wherein the bridge has on its outer side at one end thereof a projection whose bearing surface on the other bone plate lies substantially in one plane with the bearing surface of the contact arm protruding from the bridge at this end thereof. 5. Implant in accordance with claim 1, wherein at least some of the projections on the outer side of the bridge and/or the bridge itself are capable of elastic displacement or deformation such that the projections protrude less far from the edge of the bone plate on which the clip is held. 6. Implant in accordance with claim 2, wherein at least some of the projections on the outer side of the bridge and/or the bridge itself are capable of elastic displacement or deformation such that the projections protrude less far from the edge of the bone plate on which the clip is held. 7. Implant in accordance with claim 3, wherein at least some of the projections on the outer side of the bridge and/or the bridge itself are capable of elastic displacement or deformation such that the projections protrude less far from the edge of the bone plate on which the clip is held. 8. Implant in accordance with claim 1, wherein the bridge is of arcuate design in the longitudinal direction with a concave outer side and is capable of elastic deformation into a more stretched position. 9. Implant in accordance with claim 1, wherein the bridge passes at least at one end thereof into the respective adjacent contact arm via a bend protruding outwardly relative to the bridge and forming a projection for fixing the clip on the other bone plate. 10. Implant in accordance with claim 9, wherein a projection is formed on one side of the bridge by a bend, and a further projection is formed on the other side thereof by a projecting lug protruding transversely from the bridge. 11. Implant in accordance with claim 10, wherein the projecting lug has openings for receiving bone screws. 12. Implant in accordance with claim 4, wherein the bridge passes at least at one end thereof into the respective adjacent contact arm via a bend protruding outwardly relative to the bridge and forming a projection for fixing the clip on the other bone plate. 13. Implant in accordance with claim 12, wherein a projection is formed on one side of the bridge by a bend, and a further projection is formed on the other side thereof by a projecting lug protruding transversely from the bridge. 14. Implant in accordance with claim 13, wherein the projecting lug has openings for receiving bone screws. 15. Implant in accordance with claim 1, wherein several projections are arranged on the outer side of the bridge in the central area thereof and are distributed over the length thereof. 16. Implant in accordance with claim 15, wherein the projections are designed so as to be of sawtooth-like cross section. 17. Implant in accordance with claim 15, wherein the distance of the projections from the bone plate on which the contact arms fix the clip is increasingly larger from one end of the bridge to the other. 18. Implant in accordance with claim 1, wherein the contact arms are capable of swivelling apart in a resilient manner. 19. Implant in accordance with claim 1, wherein the contact arms have at their free end projections which are directed towards each other. 20. Implant in accordance with claim 19, wherein the projections are formed by bends in the contact arms. 21. Implant in accordance with claim 19, wherein the projections on the contact arms taper to a point. 22. Implant in accordance with claim 1, wherein each contact arm is divided by cutouts extending from the free end thereof into at least two single arms arranged adjacent to each other. 23. Implant in accordanc e with claim 1, wherein perforations are arranged on one or both of the contact arms for receiving bone screws. 24. Implant in accordance with claim 1, wherein the contact arms have a profile on their inner side facing the bone plate. 25. Implant in accordance with claim 24, wherein the profile comprises a number of projections of sawtooth-like cross section. 26. Implant in accordance with claim 1, wherein said implant consists of a metal which is well tolerated by the body. 27. Implant in accordance with claim 1, wherein said implant consists of an absorbable material. ; 0693297, EP; WO96/008305, WO to form a pair of end pockets and a central open pocket between the pair of end pockets; the central open pocket having first and second edges; a first plurality of securing elements secured to one of the first and second edges; a second plurality of mating securing elements secured to the outside surface of the flexible pouch, whereby the flexible pouch and the plurality of electrical motors are removably secured in the central open pocket by attachment of the first plurality of securing elements to the second plurality of mating securing elements; at least one pair of mating holding elements secured to the scarf for selectively holding the scarf wrapped around the flexible pouch; and the controller including a rotatable control knob and an electrical power source connected between a microprocessor and the plurality of electrical motors to regulate the flow of electricity to the plurality of electrical motors to ensure that the electrical motors start and vibrate. 14.
