Title: Extraction of mercury and gold from mine tailings
Inventor: KNELSON BENJAMIN
IPC: B04B3/00
Filed: 1994-05-17
Granted: 1999-03-30
Abstract: A centrifugal separator includes a centrifuge bowl having a plurality of annular rings on the peripheral surface. An outer bowl provides a jacket from which water is injected through holes in the inner bowl into recesses between the annular rings. Feed materials containing gold and mercury are separated so that the gold and mercury is collected with the heavies in the recesses. The liquid mercury escapes through the holes in the inner bowl onto the inner surface of the outer bowl which is provided with an annular receptacle and is shaped to collect the mercury at the receptacle axially spaced from the open mouth of the bowl. A plurality of outlets in the annular receptacle allow the escape of the mercury into a secondary launder inside the outer launder for the main discharge materials from the open mouth. The liquid mercury is thus collected separately from the solid heavies within the bowl and separately from the discharged light material.

Title: Process and apparatus for the wave soldering of circuit boards
Inventor: CONNORS ROBERT W
IPC: B23K1/08
Filed: 1995-02-20
Granted: 2002-05-28
Abstract: A circuit board (26) is wave soldered as it is carried by a conveyor (30) through a solder wave (16); established in a solder reservoir. Disposed on both sides of the solder wave are gas plenums (240, 250) which discharge shield gas. Each gas plenum includes a top wall (245, 255), a side wall (246, 254), and a bottom wall (243, 253). The side wall is spaced horizontally from the wave, and the bottom wall is submerged within the solder (11). The side and (optionally) top walls include orifices (245, 255) for directing shield gas: (i) at high velocity toward the solder wave to protect the solder wave with an atmosphere of shield gas, and (ii) upwardly toward an underside of the circuit board to strip entrained air therefrom. Instead of being submerged within the solder, the bottom wall could be spaced above the solder and provided with orifices to emit shield gas downwardly between the plenum and solder reservoir to create an inert atmosphere above the solder. A divider (70, 270) disposed within the plenum forms sub-chambers communicating with orifices in respective walls of the plenum so that different gas velocities can be entitled from the orifices. The gas ple nums can be rotatably adjustable and further adjustable either vertically or horizontally.

Abstract: A multiple beam laser sintering device includes a sintering beam (64) having a focal point at a powder bed (68) and at least one defocussed laser beam (116) incident on a region near the focal point of the focussed beam (64). The sintering beam (64) raises the temperature of the powder (84) to the sintering temperature.  The defocussed beam (116) raises the temperature of the material surrounding the sintering beam (64) to a level below the sintering temperature, thereby reducing the temperature gradient between the sintering location and the surrounding material. Thermal radiation may be measured from one or both beams and used to control the power of one or both beams and the power of one or both beams may be controlled to maintain the temperature at a desired level.  Alternatively, a plurality of defocussed beams may be used to provide either a plurality of thermal gradient steps, or to control the temperature of each region around the sintering point independently.

Abstract: A transportation system is particularly useful for liquid carrying tanks. Each tank is mounted on a carrier unit and plural carrier units are transported by a single trailer or other vehicle. The trailer has an adjustable height, while each of the tank carrier units has adjustable height legs on its opposite sides. The units are loaded by backing the trailer under the carrier unit with the carrier unit legs extended and the trailer lowered. The trailer is then raised to lift the carrier unit to a transport position and the legs are in turn lifted to the transport position. For unloading, the reverse procedure is adopted, with the carrier unit legs being lowered to the ground and then the trailer being lowered and the trailer being pulled out from under the carrier unit. The carrier units are arranged with an angled base so that when the carrier is pulled out, the carrier unit will tilt forwardly to provide maximum drainage of the tank.
