  • Patent number: 10364190
    Abstract: A method of producing a component of a composite of diamond and a binder, wherein a Hot Isostatic gas Pressure process (HIP) is used, includes the step of enclosing a de-bound green body having compacted diamond particles in an infiltrant. The method includes the further steps of enclosing the de-bound green body and the infiltrant in a Zr-capsule that has Zirconium as a main constituent and sealing the Zr-capsule, and applying a predetermined pressure-temperature cycle on the unit formed by the de-bound green body, infiltrant and capsule in which the infiltrant infiltrates the de-bound green body and the de-bound green body is further densified in the sense that the volume thereof is decreased.

  • Publication number: 20170021423
    Abstract: A method for manufacturing a metallic component including the steps of providing a capsule, which defines at least a portion of the shape of the metallic component, arranging metallic material in the capsule, sealing the capsule, subjecting the capsule to Hot Isostatic Pressing for a predetermined time, at a predetermined pressure and at a predetermined temperature, and optionally, removing the capsule. The metallic material is at least one pre-manufactured coherent body, which pre-manufactured coherent body being made of metallic powder, wherein at least a portion of the metallic powder is consolidated such that the metallic powder is held together into a pre-manufactured coherent body. At least one portion of the pre-manufactured coherent body is manufactured by Additive Manufacturing by subsequently arranging superimposed layers of metallic powder.

  • Patent number: 7931855
    Abstract: A method of reducing the oxygen content of a powder is provided. A canister is prepared with a getter, filled with the powder to be densified, sealed and evacuated. The canister is subjected to a hydrogen atmosphere at an elevated temperature whereby hydrogen diffuses into the canister through the walls thereof. The hydrogen forms moisture when reacted with the oxygen of the powder and the moisture in the reacted with the getter in order to remove oxygen from the powder to the getter. The atmosphere outside the canister is then altered to an inert atmosphere or vacuum, whereby hydrogen diffuses out of the canister. A dense body having a controlled amount of oxygen can thereafter be produced by conventional powder metallurgy techniques.

  • Publication number: 20060123230
    Abstract: The invention automatically controls whether displayed web pages and associated frames displayed within a web browser are secure or non-secure. A dynamic “Web Component” remotely controls web page security states. The Web Component uses the same script and HTML for all implementations or instantiations of the Web Component, regardless of how many unique clients make use of the Web Component. This code reuse is accomplished using entry web pages, or “entry points,” to set the value of function properties or parameters of the Web Component for dynamically and controlling the security state of a web page having at least two frames. The script and/or HTML source code of the Web Component pages does not change based on each new implementation or instantiation. Consequently, little setup work is required for each implementation, and only a basic verification test pass is needed for each unique automatically customized Internet web page.

  • Publication number: 20060064471
    Abstract: Internet web pages displayed via an Internet web browser or other applications are automatically customized. Dynamic “Web Components” are used to automatically customize web pages. Further, these Web Components use the same script and HTML for all implementations or instantiations of the Web Component regardless of which, or how many, unique local clients make use of the Web Component. This code reuse is accomplished by using entry web pages, or “entry points,” as described in further detail below, to set the value of function properties or parameters of the Web Component for dynamically and automatically generating a web page. The script and/or HTML source code of the Web Component pages does not change based on each new implementation or instantiation. Consequently, little setup work is required for each implementation, and only a basic verification test pass is needed for each unique automatically customized Internet web page.
