  • Publication number: 20150128765
    Abstract: A starting material 2 in the form of a magnesium-containing metal melt is present together with the upper region 32 of a condensation vessel 3 in the upper region 11 of a retort 1 heated by the external heating element 5, wherein the steam produced according to the arrows 91, according to arrow 92, enters the upper region 32 of the condensation vessel 3 through the opening 31 below the cover 4 which provides protection from unwanted ingress of contaminated magnesium melt, wherein said steam condenses in the lower region 12 of the retort which is heated by a second heating element 51, below the line 8 corresponding to the melting point isotherm of magnesium, to give the high-purity magnesium melt 21 in the lower region 33 of the condensation vessel 3.

  • Patent number: 7995195
    Abstract: The invention relates to a method for optically monitoring the progression of a physical and/or chemical process taking place on a surface of a body in which the surface radiation which emanates from part of the surface during the physical and/or chemical process, is measured with the aid of a measuring device, in particular a sensor. In order to develop a method of this kind such that sintering processes can also be monitored in a firing furnace having thermal radiation equilibrium, the invention proposes to emit the radiation (14) having a radiation spectrum that differs from the surface radiation, to the surface (10) by means of a radiation source (15) and to measure the radiation with the aid of a measuring device (16).

  • Publication number: 20070108668
    Abstract: Disclosed is a preferred mold design for producing plastic, molded preforms, which may be blow-molded into a container of a final, desired shape. A preferred mold includes a temperature control system for maintaining the preform mold at a desired temperature. The temperature control system can pass fluid through channels within the preform mold to cool plastic that is injected into the preform mold. In some arrangements, a mold comprises a neck finish mold, the neck finish mold configured to transfer heat away from the molding surface toward a channel conveying a working fluid. A heat transfer member may be at least partially positioned within the channel to transfer heat to the working fluid. In some embodiments, the mold comprises a high heat transfer material.

  • Patent number: 6849230
    Abstract: A mixture of two particulate phases used in the production of a green compact that can be sintered at higher temperatures. The first phase contains particles that consist of a metal and/or a metal allow and/or a metal compound. The second phase contains particles from the group of the inorganic compounds that do not release any decomposition products at temperatures of more than 400° C., that are interstitially soluble in the sintering metal phase, and/or that react with the second phase to stable compounds. The mixture, by providing the second phase, is effective in supporting the fine structure of the first phase against the forces of surface tensions during the sintering process. During sintering, the second phase remains thermally stable and substantially chemically inert with respect to the first phase.

  • Patent number: 6790254
    Abstract: The invention relates to a method for producing a metal alloy, in which in a vessel at overpressure a certain desired content of an alloying constituent, which is gaseous in its normal state, is fed to said metal alloy. The method is designed such that precise addition by alloying of an alloying constituent which is gaseous per se, to a steel alloy subjected to overpressure in a pressure vessel, is made possible.

  • Patent number: 5217664
    Abstract: Process for the production of a component, in which metal or ceramic powder (6) is applied under centrifugal force to the inner wall of a gas-permeable mold (13), which is under reduced pressure and is located in a reduced-pressure vessel (10), and precompacted, after which the mold (13) is removed from the vessel (10) and sintered. The mold (13) consists of a heap of ceramic grains with an organic binder having high strength between room temperature and a temperature just below the sintering temperature, in order to support the powder (6) to be sintered to give the component. When sintering starts, the binder evaporates or burns away, as a result of which the mold (13) substantially loses its supporting action for the component. Binder: aminolic, phenolic, furan resin.

  • Patent number: 5169577
    Abstract: A process for the production of a complex component made of metal, ceramic or plastic, in which process powder (7) is blown by means of a transport gas into a gas-permeable negative mold (14), which is under reduced pressure and is located in a container (11), and pre-compacted, after which the negative mold (14) is removed from the container (11) and the green compact is sintered, either in a separate ceramic supporting composition or in the negative mold (14) itself, which consists of ceramic. The process allows production of a hollow body or of a layered body as the component by programming the powder injection.
