  • Patent number: 4386956
    Abstract: An improved method for recovery of metal, particularly aluminum, from metal bearing dross utilizes a trough for collection of the dross. A wedge member compresses the dross in the trough. In this manner, metal is decanted from the compressed dross and flows through slots in the bottom or passages in the walls of the trough for collection in a pan, or becomes concentrated at the edges or walls of the volume of dross. The trough and wedge members also serve to cool the dross material thereby diminishing metal loss due to thermite reaction. The compressed dross coalesces and solidifies, is broken and is mechanically separated. The larger dross components from the separation process are substantially metallic and may be recycled through the furnace. The remaining components are charged in a vortex melting furnace for the lowest possible melt loss. This also effects segregation of the remaining metal from the dross by melting the metal and allowing the dross to rise to the top of the bath.

  • Patent number: 4339720
    Abstract: Apparatus and method for generating a record of telluric noise which is substantially free of induced polarization signals and is suitable for removal of noise components from induced polarization signal records. The apparatus includes a single pair of telluric noise sensing electrodes positioned in alignment with, but substantially beyond the ends of, a somewhat conventional induced polarization electrode spread. The method includes recording of telluric noise occurring at the time of detection of induced polarization signals and the subtraction of a fraction of the telluric noise record from the induced polarization signal records.

  • Patent number: 4312064
    Abstract: A communication transmission system includes one or more modulated carrier communication channels in which a receiver has a modified vestigial side band filter for eliminating phase cancellation. Accurate design of the modified vestigial side band filters at the receivers, further reduces susceptibility to frequency drift caused by component aging and component response to environmental changes. The system has particular utility in multiple channel carrier telephone communication systems which utilize limited available band width for providing a maximum number of communication channels over an extended length communication line.

  • Patent number: 4226714
    Abstract: The present invention is directed to a method and apparatus for maintaining steady state conditions in a separator. Steady state is maintained by controlling mass flow rates of influent to, and underflow from the separator. Specifically, an influent specific gravity and flow rate signals are monitored by an influent mass flow controller. That controller responds to variation in these signals to maintain a constant mass feed rate into the separator. A mass flow signal, comprising a composite of influent specific gravity and influent mass flow signals, is produced. That signal is fed to a thickener controller which also monitors mass flow of the underflow. The thickener controller adjusts the mass flow rate of the underflow in response to the influent mass flow signal. However, fluctuation of an interface level between clear and unclear areas of the thickener can effect flow rate adjustment.

  • Patent number: 4193968
    Abstract: The invention provides a process for recovering gallium from calcined clay leached with hydrochloric acid. The leach solution containing aluminum, ferric and gallium chlorides is treated by ion exchange to first remove aluminum ions, following which the solution containing ferric and gallium chlorides is treated to reduce the ferric ions to ferrous ions. The reduced solution is acidified with hydrochloric acid sufficiently to insure that the gallium is present in the form GaCl.sub.4 - ions, and is then again treated by ion exchange to separate the ferrous ions from the gallium for ultimate recovery of the latter.

  • Patent number: 4178174
    Abstract: The invention disclosed is a process for the direct production of copper metal by directing an aqueous slurry of cupriferous material into a molten cupriferous bath maintained at a temperature of 2100.degree. to 2400.degree. F. Neither the cupriferous material of the slurry nor that of the bath contains sufficient sulfidic materials to maintain the bath temperature by oxidation of these sulfides, so a carbonaceous fuel is incorporated in the slurry. Such fuel-containing slurry together with an oxygen-containing gas is directed at high velocity against the bath surface at an angle of about 20.degree. to 40.degree. from the horizontal. The incorporation of fuel in the injected slurry provides a heat source for the maintenance of the 2100.degree. to 2400.degree. temperature necessary for smelting the cupriferous material of the slurry.
