Abstract: In its preferred embodiment, my invention provides a solution for a reusable product that provides the ability to conveniently, effectively and immediately cool a consumable liquid in a container regardless of where you are, without the delay involved by requiring to place any portion of the container into a refrigerator, to increase the time that a cooling agent's (ice) lowered temperature is preserved prior to exposure to the consumable liquid, to provide enhanced cooling impact through direct and maximum surface contact between the cooling agent and consumable liquid, to do so for any liquid the person desires to consume and that is not limited in its design/fit/configuration in order to accommodate a specific commercially available prepackaged container.

Abstract: A circular tray having an upper surface shaped to incline downwardly from a center to an outer circumference. The tray including annular grooves for collecting gold. A crank is connected to the tray for rotating the tray. The tray is supported with a stand having at least one elongate arm extending radially across the tray above the tray in spaced apart relation thereto. Multiple loops of a line material are attached in spaced apart depending relation along the elongate arm in such a way that the bottom portion of the loop extends in a direction which is oblique with the elongate arm. Each loop is sized to have the bottom portion resting in close proximity with the upper surface of the tray so that when the tray is rotated, the loops mechanically move ore across the surface of the tray from the center to the outer periphery.

Abstract: A device for de-dusting, i.e., removing dust, from a particle flow in an enclosure. The device is optionally associated with a unit for dense loads which supplies the particle flow. The device is useful, for example, for removing dust from catalyst particle flows and from adsorbent particle flows. It is also useful for removing dust from grain or cereal particles, for example, being supplied to a silo.

Abstract: Dense, tramp material, is efficiently separated in a comminuted cellulosic fibrous material feed system, for example in a chemical cellulose digester feed system, in a simple but effective matter. By merely utilizing a generally vertical conduit and a slurry flow within it (which may be augmented by high speed liquid introduction), that is caused to turn in a radiused path, centrifugal force allows separation of the tramp material into a cavity beneath the radius transition without requiring any mechanical element to engage the slurry. Appropriate purges, baffles, and discharge mechanisms may be provided. Alternatively, a tramp material separator may be built into an otherwise conventional metering screw in a digester feed system, or one or more centrifugal separators can be provided downstream of the slurry pump in a chip slurry transport system or digester feed system.

Abstract: A plurality of water cups (80) are mounted at the outer periphery of a rotating gold pan (12). In use, the gold pan (12) is supported in a rearwardly leaning position with a lower edge portion in water. During rotation of the gold pan (12), the water cups (80) collect water as they rotate into and through the water. The water cups (80) lift the collected water as they rotate up out of the water. The water cups (80) release water that they carry into the gold pan (12). The released water helps separate gold particles from other particulate material and moves substantially clean gold particles along the valleys (69) of the bottom wall (52) of the gold pan (12) to a hub cup (54).

Abstract: An enhanced gravity laminar flow separation system is provided by a conical drum which has a plurality of flow channels along the inside surface of the drum. Feed material for separation is fed into the drum and accelerated by an impeller so as to enter the channels at a feed end at the base of the drum and to move along the channels to a discharge end at the mouth of the drum of increased diameter. Heavies are stripped from the base of the channel and the lights escape from the open mouth of the bowl longitudinally of the channel. The channel changes cross-section from the feed end to the discharge end decreasing in width and increasing in depth by the addition of a V-groove at the base. Tangential forces from the acceleration of the material which act on one side of the channel are balanced by the shape of the channel to provide symmetrical flow.

Abstract: A centrifuge bowl of the type having a shell including a peripheral wall and a cast inner liner attached to the inside surface of the peripheral wall is modified by the provision of a plurality of punched channel portions which extend inwardly into the bowl from peripheral wall to define a U-shaped channel with severed ends. During the casting process the casting plastics material extends into the recess behind each channel portion and thus when set forms an insert portion which anchors the liner to the channel portion and thus to the peripheral wall. Openings for the entry of fluidizing water are then drilled through the insert portion from the outside of the shell through one end of the channel portion and through the liner into the interior of the bowl.

Abstract: A centrifugal jig of the type in which a feed slurry is introduced into a rotating chamber bounded radially by a screen provided with ragging on its inner surface. The ragging is repetitively dilated in a circumferential sequence while the container rotates.

Abstract: A gravimetric cell for centrifugal separation of fine coal by density has a cylindrical body and a butterfly valve or other apparatus for selectively sealing the body radially across the approximate center of the cylinder. A removable top is provided which seals the cylinder in the centrifuge and in unvented areas.

Abstract: A centrifugal jig screen with a rotating hutch is supplied with inwardly directed pulses by overlapping fluid supply nozzles and pulse blocks coaxially arranged about the jig axis. Fluid not directed to the hutch interior in sharply defined pulses is diverted into a surrounding shroud, permitting the incoming fluid flow to be substantially uninterrupted during jig operation. Wedge surfaces about the hutch prevent buildup of separated materials as the are discharged from the hutch.

Abstract: Apparatus and method for separating intermixed particles of differing densities including a separator bowl rotatable about an axis inclined to the horizontal plane and having a base wall and a peripheral wall, and a plurality of radially-spaced chambers disposed around the peripheral wall and extending from adjacent the base wall to the upper edge of the peripheral wall, each of the chambers having chamber walls converging with one another away from the axis to a discharge port at a height intermediate the base wall and the upper edge. The bowl is rotated and a mixture of the particles is fed into the lower portion of the bowl and the mineral particle fraction discharged from the discharge port of the bowl is collected.

Abstract: Separating elements (14) arranged about a central shaft (1a) rotate in common about the main axis (A) and individually about their longitudinal axes (B). A centrifugal distributor (6) distributes fine-grain mineral mixture mixed with fluid uniformly to the separating elements (14). In each separating element (14) the partial material flow (2a) is set in rotation about the longitudinal axis (B) by entrainment vanes (18) arranged in a first separating element section (15a) and the heavy fraction is centrifuged on to the separator wall (16a). In the second section (15b), formed as conical tubular worm conveyor, which contains no entrainment vanes, the heavy fraction is transported to the collecting chamber (21) and discharged through first discharge openings (22), the fine-grain mineral mixture being fluidized in pulsation on the separating wall (16b) by the combined rotating movements and the heavy fraction being concentrated.

Abstract: A centrifugal separator has a rotating tub with annular dams to trap the heavier components of the slurry fed into the tub through a centrally located feed tube. The latter rotates at a speed slightly different from that of the tub and supports radially extending spokes that have depending tines provided with lower nozzle defining ends in the annular spaces between the dams. Water under pressure emanates from these nozzles. An alternative tub configuration has annular water manifolds inside these annular spaces to provide water under pressure to nozzles in the tub itself for supplementing the action of the nozzles in the depending tines.

Abstract: A centrifugal classification apparatus for separating particulate solids, such as sand, in a fluid mixture into fractions having common physical characteristics, such as particle size and/or weight. The apparatus includes a frusto-conical hollow shell rotatable about a longitudinal rotation axis and having an inlet opening at one end for receiving the fluid mixture and an outlet opening at its other end; a discharge aperture in the shell between its inlet and outlet openings through which the solids may pass; and a collecting compartment fast with the shell and located about the discharge aperture for collecting a fraction of the solids having common physical characteristics. The compartment extends radially outwardly from the shell and has a radial depth greater than the maximum longitudinal width of the aperture, a closable discharge orifice at its radially outer end; and a valve at the orifice for controlling discharge of solids from the compartment.

Abstract: An improved rotatable separator unit for gold or other ore separation is provided which gives enhanced ore recovery and can be installed on a mobile frame for transport to a mine site. The separator includes an upright, preferably frustoconical, ore-receiving bowl equipped with a plurality of generally horizontal vertically spaced apart ribs secured to the inner face of the bowl and extending inwardly therefrom in a "stair step" fashion; a central stationary conduit pipe is also provided for introduction of material into the bowl, along with powered means for rotation of the bowl about an upright axis. In particularly preferred forms, the separator is provided with a plurality of circumferentially spaced, stationary, obliquely oriented baffles located within the bowl and adjacent the inner edges of the bowl ribs for creating turbulence at the regions of the ribs and facilitating separation of the ore from undesired debris such as relatively large rocks.
