  • Publication number: 20090214073
    Abstract: An adjustable ear-hook earphone includes an audio earphone and a substantially auriform ear-hook connected to the earphone and configured to engage an ear of a user to hold the earphone adjacent the ear. The ear-hook has an outer portion configured to face generally away from the ear and a compressible inner portion configured to face generally toward the ear. The inner portion is compressible between a compressed position and a plurality of successive, expanded positions such that the expanded positions exert a force on the ear of the user.

  • Patent number: 6783725
    Abstract: A coated sintered cemented carbide body includes a cemented carbide body, a first layer adjacent the cemented carbide body, the first layer including Ti(C,N) and having a thickness of from about 3 to about 20 &mgr;m, an alumina layer adjacent said first layer, the alumina layer including &agr;-Al2O3 or &kgr;-Al2O3 and having a thickness of from about 1 to about 15 &mgr;m, and a further layer adjacent the aluminum layer of a carbide, carbonitride or carboxynitride of one or more of Ti, Zr and Hf, the further layer having a thickness of from about 1 to 15 &mgr;m. A friction-reducing layer, including one or more of &ggr;-Al2O3, &kgr;-A12O3 and nanocrystalline Ti(C,N) and having a thickness of from about 1 to about 5 &mgr;m, can be adjacent to the further layer. A method to cut steel with a sintered cemented carbide body where the alumina is &agr;-Al2O3 and a method to cut cast iron with a sintered cemented carbide body where the alumina is &agr;-Al2O3.

  • Patent number: 6666288
    Abstract: The present invention relates to cutting tool insert consisting of a tungsten carbide based hard metal substrate and a coating. The hard metal consists of about 4-15 wt-% binder phase with face centered cubic structure and a composition of 35-65 wt-% Fe and 35-65 wt-% Ni in addition to dissolved elements. As a result, inserts have been produced with at least as good performance in machining as conventional state-of-the-art inserts with Co-based binder phase. The insert can be applied in milling and turning of low and medium alloyed steels as well as stainless steels.
