  • Patent number: 7891095
    Abstract: The present invention relates to a novel method of producing in one and the same operation precious hallmarked precious metal products. The method is particularly suited for production of such precious metal products, i.e. jewelry and objets d'art, which have complex geometries. The basic principle of the invention is the use of the free form fabrication FFF, method known per se which involve a stepwise build-up in layers of the product from a precious-metal-containing metal powder.

  • Patent number: 7754166
    Abstract: A disinfection apparatus is disclosed for disinfecting fluid cleaning of health care objects and the like. The disinfection apparatus includes a fluid system for supplying fluid to a chamber, an at least partially movably arranged first connecting part with an active and an inactive position, which is adjusted to a mobile object holder, which object holder is to be placed in the chamber and has a second connecting part connectable to the first connecting part. The first connecting part is movable, under the action of the pressure in the fluid system, between a position disconnected from the holder and a position connected to the active position, i.e. to the second connecting part. A fluid connectable mobile object holder is also disclosed, which is adapted to be placed in a chamber of a disinfection apparatus as stated above.

  • Patent number: 7478978
    Abstract: The present invention relates to a tool head preferably for milling. The tool head is connectable to a toolholder. The tool head includes a cutting portion and a mounting portion. The mounting portion includes an axial stop surface and a radial stop surface. Dimensions and tolerances of the axial stop surface and the radial stop surface are selected such that the axial stop surface will abut an axial stop on the toolholder to prevent axial movement of the toolholder relative to the tool head beyond the axial stop surface and the radial stop surface will be disposed proximate a radial stop of the toolholder to limit radial movement of the tool head relative to the toolholder when an integral fastening portion of the tool head and an integral fastening portion of the toolholder are fastened directly to one another and the axial stop surface and the axial stop abut.
