  • Patent number: 6034985
    Abstract: Method for recognition of noble metals otherwise not recognizable in base material clusters includes using an electric arc furnace in which base material clusters are disintegrated to free atoms or are alloyed with other components of the base materials, and are able to be recovered by conventional recovery techniques once they are recognized. The base material includes the products of smelting processes, pellets of compacted raw material, like anode mud or waste material, and the base materials are melted utilizing the heat from a dc electric arc furnace.

  • Patent number: 5878074
    Abstract: A crucible is disclosed for use in coating a substrate with deposition materials by electron-beam evaporation. The crucible is configured to be inserted into an evaporator pot; it has a bottom and at least one sidewall extending upwardly from the bottom and terminating in a rim, such that the bottom and sidewall define a reservoir for containing the deposition material, and the rim defines a mouth out of which the deposition material may evaporate. A lip extends upwardly from a predetermined section of the rim which shields the spattering of deposition of material onto the evaporator pot during the evaporation process. A improved method is also disclosed for performing electron-beam evaporation with the present invention crucible.

  • Patent number: 5272718
    Abstract: A method and apparatus for forming a stream of molten material. The apparatus includes a melt container having a bottom wall in which is formed an aperture. A funnel is adapted and constructed to receive molten material from the aperture in the container, and includes a plurality of fluid-cooled metallic segments. The funnel segments define an inner funnel contour that decreases in cross-sectional area from the inlet end to the outlet end of the funnel. An electrically conductive coil surrounds the funnel, and has a shape corresponding to the outer shape of said funnel. A source of medium-frequency current in selective electrical connection with the coil. The method begins with the step of providing a predetermined quantity of molten material in a melt container. A metallic funnel is provided in fluid communication with the melt container, and includes a plurality of fluid-cooled funnel segments. The method also includes the step of providing an electrically conductive coil surrounding the funnel.

  • Patent number: 5263044
    Abstract: Method for recognition of noble metals otherwise not recognizable in base material clusters includes using an electron beam furnace in which base material clusters are vaporized by means of an electron beam gun, and the vaporized materials are condensed as free atoms or are alloyed with other components of the base materials, and are able to be recovered by conventional recovery techniques once they are recognized. The base material includes the products of smelting processes, pellets of compacted raw material, like anode-mud or waste material, and the base materials are remelted utilizing the heat from electron beam guns for the remelting.

  • Patent number: 4973818
    Abstract: A device and a method for the control and monitoring of a deflectable electron beam is provided for the working of metal wherein the electron beam is not permitted to go beyond an allowed working area. With this device with the aid of a Teach-In method the limits are entered into a computer. The computer generates an image of the areas allowed for the electron beam in a particular area of a special memory. This memory is so organized that the addresses of the point of the particular areas correspond to the digitized coordinates of the point of impingement of the electron beam. The characterization of the allowed and forbidden target points of the electron beam takes place through placing or deleting respectively the assigned bits in the special memories.

  • Patent number: 4677642
    Abstract: The electron bombardment furnace (B) consists of two confinement grid sections (26,28) which may be moved and separated from each other. Inside the bombardment furnace, a tungsten element (14) is enclosed. The material specimen (18) is located within the tungsten element and grounded by means of grounded support wires (20,22) connected to the respective sections of the furnace. The material specimen (18) is supported on the ground wires and heated by electron bombardment until melt occurs. The furnace sections are separated in opposite directions causing the ground wires to pull from the surfaces of the specimen, leaving the specimen freely suspended in the process chamber without the action of external forces. The specimen remains in its melt condition in the processing chamber where it can be undercooled without external forces acting on the specimen, which would cause dynamic nucleation.
