Abstract: A sorting system for sheeted material is presented, the sorting system including a path for travel of the sheeted material; an entrainment gas source for providing a first flow of gas in a direction substantially the same as the path for travel of the sheeted material; a plurality of receiving bins for receiving the sheeted material; a directional gas source associated with at least one of the plurality of receiving bins for providing a flow of gas directed to maintain the sheeted material entrained in the first flow of gas; a sorter associated with at least one of the plurality of receiving bins for directing selected ones of the sheeted material into such receiving bin.

Abstract: A waste water settling apparatus includes a closed cylindrical vessel supported on and vertically extending above a base, two vertical vibrators joined to the closed vessel for vibrating the vessel, and a drive spring assembly joined between the vibrators and the vessel for multiplying the vertical force of the vibrators. The closed cylindrical vessel includes a rotary valve joined to the lower portion of the vessel for discharging densified solids settled out of the waste water.

Abstract: A self-contained gold separation kit adapted for easy carrying using a shoulder strap uses a single-spring rocker assembly for agitation of stream bed materials for separation of gold. The main kit elements include a sluice box, material tower and collector tray that are contained for carrying within a box, and in use those elements are then rotatably mounted above the carrying box. That box also serves to contain a quantity of water to be used repeatedly in washing out the bed materials, hence the device can be used at a distance away from stream bed. The weight of that water also serves to prevent the device as a whole both from moving about while being rocked and from tipping over. A dipper is included for dipping water over the bed materials, and also a gold pan for the final separation of the gold and a collector tray for collecting tailings from the gold separation.

Abstract: Method and apparatus (10) are provided for separating and classifying particles (48,50,56) by dispersing the particles within a fluid (52) that is upwardly flowing within a cone-shaped pipe (12) that has its large end (20) above its small end (18). Particles of similar size and shape (48,50) migrate to individual levels (A,B) within the flowing fluid. As the fluid is deflected by a plate (42) at the top end of the pipe (12), the smallest particles are collected on a shelf-like flange (40). Ever larger particles are collected as the flow rate of the fluid is increased. To prevent particle sticking on the walls (14) of the pipe (12), additional fluid is caused to flow into the pipe (12) through holes (68) that are specifically provided for that purpose. Sticking is further prevented by high frequency vibrators (70) that are positioned on the apparatus (10).

Abstract: To wash and dewater solid-water mixtures in the preparation of construction materials, particularly in recycling processes (processes using recycled waste materials), a sturdy washing trough structure is formed of a sheet steel washing trough to which a vibration box (also solid) is connected on the solids discharge side in order to achieve improved dewatering, and to provide at least one "washing pulsator" and at least one "conveying pulsator", in the form of hydraulic or pneumatic organs, which engage the washing box itself. In addition, with the aid of a hydraulic or pneumatic thrust organ, the entire assembly can be swung up around a swing pivot, said swinging up being toward the solids discharge location; and/or said assembly can be swung up toward the washing water overflow.

Abstract: A riffled ore concentrating table of the reciprocating type is connected to a table support by ball bearings. The table support has one of its edges pivotably connected to one edge of a base member and the other of its edges supported by the other edge of the base member in a manner such that the elevation of one edge of the table may be adjusted with respect to the other edge of the table.

Abstract: The apparatus includes a fluid-tight housing oscillated about a vertical axis, the housing containing a central deflector separating the housing into an upper chamber and a lower chamber. Baffles are provided in both chambers, above and below the deflector. The upper baffle directs the incoming slurry radially outwardly in a torical path, throwing the particulate material toward a periphery of the housing in the first separation zone, in a gravity induced flow, through the annular passageway into the lower hopper where the relatively lighter and heavier constituents are then separated and separately discharged from the housing. A ring dam formed in the second baffle provides a recess into which the lighter constituents overflow where they are reunited with the liquid flow path and thus discharged from the housing.
