A resurfacing implant for preventing bone resection, particularly for a metacarpophalangeal, metatarsophalangeal or interphalangeal joint, including two proximal (12) and distal (40) elements respectively implanted at the end of each of the joint bones, and each consisting of an anchoring member (52, 66) and a joint head (39, 64). The heads of the proximal and distal elements have substantially th...

The invention relates to a thin, more resistant, easy to use sleeve for the packaging of compact disks. It is comprised of three distinct parts, a disk extractor (10), a central sleeve (6) wherein slides the disk in its extractor and two side sleeves arranged on each of the two sides of the central sleeve. The inlet of the side sleeve visible on the figure is designated by (9). The side sleeves ar...

The prosthesis consists of an articulated joint (2) with two projecting rods (6,8) which slide into anchoring sleeves (3,4) in the adjacent bones, with lugs (12,15) on the rods engaging with grooves (24) along the inside of the sleeves to ensure the appropriate angular position. One of the two rods is jointed to a shell (6) with a plastic insert (7) shaped to receive a ball (13) on the end of the ...

A peripheral controller interconnect/industry standard architecture (PCI/ISA)bridge is coupled between the PCI and ISA buses in a computer system. A PCI master in the system asserts address and address parity information on the PCI bus to initiate a master-slave transaction over the PCI bus. The bridge includes logic for comparing the address and the address parity information and generating an ad...

Методът е трифазен и с него се съхранява количеството на съставните материали. Първата фаза включваотделяне на феросъединенията от потока отпадъчни материали, нарязване и смилане на твърдия отпадък до малки частици с еднакъв размер, изсушаване на отпадъчния материал за отстраняване на почти цялатасвободна влага, при което отпадъкът става биологично инертен, уплътняване на изсушения отпадъчен матер...
