  • Patent number: 8157859
    Abstract: A stent made of nitinol having improved axial or radial stiffness, the stent having a support structure which comprises peripheral struts around the circumference, wherein the peripheral struts are linked to one another in the axial direction via connection struts. The support structure may assume a first compressed state and a second expanded state. The nitinol is in the support structure in a martensitic microstructure in the compressed state and largely in an austenitic microstructure in the second expanded state. One or more support structure sections, however, are entirely or partially in a martensitic microstructure in the second expanded state.

  • Publication number: 20120061230
    Abstract: A suction device has a suction pipe for aspirating fumes containing metal particles, in particular welding fumes, which aims to allow safe control of the fumes with a minimum of equipment expense and operational expense. For this purpose, an oxidation apparatus is provided according to the present invention. The particles flowing past the oxidation apparatus during operation are heated by way of a power supply and are thus oxidized.

  • Patent number: 7495197
    Abstract: In a method for heat treating a fuel assembly channel made of zircaloy, the channel is continuously moved relative to a heat-treatment device and, longitudinal sections of it are heated to the beta phase range in an inductive heating zone. The longitudinal section of the channel heated in this manner is than cooled in a cooling zone to a temperature within an alpha phase range. The heat treatment is effected by at least two heating devices, which are spaced apart from one another, operate independently of each other, and each contain at least one induction coil and together form a heating zone. The channel section is first heated using a first heating device and then heat-treated using a second heating device which has less power and in that cooling is effected using a stream of inert gas applied to the outer surface of the channel.
