Title: Electrolytic recovery of metal from dispersion using cationic ion exchange agent

Granted: 1979-08-28
Abstract: ABSTRACT OF THE DISCLOSURE        A cyclic process for selective recovery of a metal from a material which contains other metal values in addition to the selected metal, comprises leaching the material with an aqueous solution capable of leaching metal values including the selected metal from the material.  The resulting aqueous solution, containing the selected metal and other metallic contaminants, is dispersed in an organic medium comprising a cationic exchange reagent which is capable of selectively extracting the selected metal from the aqueous  solution while rejecting any other metal values in the aqueous solution.  The dispersion, comprising the aqueous solution and the organic medium containing the extracted metal, is passed as a flowing stream through a passageway defined by a conduit in which there are a plurality of mutually spaced, parallel, elongate electrodes.  Flow of the dispersion is such that it is distributed uniformly about the electrodes.  An alternating current potential is applied to the electrodes to create an A.C. electrical field within the passageway sufficient to electrically coalesce the aqueous phase of the flowing dispersion, and the aqueous phase is separated from the organic phase in a separation zone downstream from the electrodes.  The selected metal values are stripped from the organic phase by dispersing the organic phase in an aqueous acidic stripping solution.          This dispersion is then resolved into an organic phase and an aqueous phase by flowing the dispersion through a passageway as described above.  The selected metal is recovered in essentially pure form from the aqueous phase, and the organic phase can be used in further selective extraction of metal values from aqueous leach solution.

Abstract: TITLE:  APPARATUS AND METHOD FOR CONTROLLING PRESS RACKING                  Abstract of the Disclosure Press racking, or lateral movement of the movable portions of a press, occurs in certain particleboard processes during heating and pressing of the panels.  It is attributed to shingling of wood particles during the formation of a mat.  To eliminate or reduce the movement of the press, the mat is subjected to rolling engagement by a relatively small diameter roll located between the forming apparatus and the press.  The roll subjects the mat to a downward rolling pressure.  The peripheral roll surface is in contact with the newly formed upper surface of the mat and has a linear speed and direction of movement identical to the speed and direction of movement of the mat support.  A resulting wave action within the mat is caused by shear and displacement forces applied to the wood particles, such that the shingled nature of the mat is modified to reduce or eliminate re-sulting lateral movement of the press components.

Abstract: A B S T R A C T             A valve assembly for a pilot fuel injection system, which system also includes a transfer pump, a high pressure fuel pump, and a fuel injection nozzle.  The valve assembly includes a blocking valve and a metering valve in an unitary housing having a high pressure fuel inlet, a metered fuel outlet, and a fuel return outlet.  The blocking valve includes a cam ring operating a spool type valving member which opens and closes the high pressure inlet to the metering valve in a timed phase relation with an engine.  The metering valve includes a cam ring, a spool type valving member, a spring, and a dump means.  The cam ring has a single lobe which smoothly increases on one side and abruptly decreases in two steps on the other side; the smooth side slides the spool in one direction at velocities proportional to engine speed while the inlet in closed by the blocking valve; and the spring moves the spool along a two stepped path at velocities independent of engine speed while the inlet is open.      The spool meters a pilot charge to the metered fuel outlet during the second step.  The dump means connects the metered fuel out-let to return at some point during the second step, thereby terminating the flow of the main charge to the engine.  Spool rotating means responsive to throttle position vary the dump means connecting point, thereby varying the main fuel charge amount flowing to the engine.  An alternative embodiment of the stepped cam ring comprises two concentric and relatively moveable rings for varying the timing of the charges with respect to each other and the engine.

Granted: 1980-03-25
Abstract: ABSTRACT          Process, structure, and aqueous bath for recovering oil from tar sand, known also simply as oil sand.  The process includes the steps of passing the tar sand through, or sub-jecting the same to a diluent, to reduce the internal fluid friction or viscosity of the oil layers surrounding each sand particle, and then bringing together the "sand", i.e. the sand particle plus its thinned oil layer, and an aqueous bath having a slightly raised specific gravity and also a wetting agent.          The purpose for the wetting agent is to allow the sand particles to fall to the bottom of the processing tank as sludge.  The raised specific gravity of the water, which is still substan-tially less than that of sea water, by the Archimedes' principle, causes the released globules or droplets of oil to be accelerated rapidly to the surface of the water, thereby escaping recapture or admixture with the descending sand particles.  The now dilute oil is recovered, separated, and the diluent is reused in the tank.  In-situ and bath recovery by the above process is likewise practicable.
