Title: Process for separating liquids and solids from whole tailings from a hot water extraction process for recovering bitumen from tar sand
Inventor: FUHR BRYAN J

Abstract: "PROCESS FOR SEPARATING LIQUIDS AND SOLIDS FROM WHOLE TAILINGS     FROM A HOT WATER EXTRACTION PROCESS FOR RECOVERING                 BITUMEN FROM TAR SAND"                       ABSTRACT OF THE DISCLOSURE Whole tailings are mixed with lime to cause fines to agglomerate with coarse particles.  The agglomerates settle at the same rate as the coarse particles during subsequent vacuum filtration, thereby evenly distributing the fines in the coarse sand in the filter cake.  Blinding of the filter is thereby avoided.  The level of lime addition is correlated with the fines content of the tar sand, thereby ensuring that maximum filtration rate is achieved.

Abstract: ABSTRACT OF THE DISCLOSURE          In a flotation basin a flotation zone and a pure liquid zone are formed which are separated by filter means. A liquid containing suspended matter is introduced into the flotation zone via an inlet and subjected to pressure release flotation by saturating pure liquid with pressurized gas under a pressure in the range of 3 to 8 bar and injecting the pressurized gas saturated liquid into the flotation zone in the region of the inlet. The flotated mud accumulating at the surface of the liquid is removed laterally by removal means coacting with the filter means or is removed by means of a combined filtering and removing device together with non-flotatable suspended matter on a filter web circulated or passed through the flotation basin. The mud is predried on the filter web and separated therefrom by redirecting its run, if desired, with assistance by a scraper. The mud falls into a collecting container separated from the flotation basin or its contents by a partition. The outlet is disposed in the pure liquid zone downstream from the filter web or between the runs thereof with respect to the direction of liquid flow.   The pure liquid is discharged by a pump controlled in depen-dence on the inflow.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention is a universal blending system and method for blending the material contents of a silo having a predetermined interior cross-sectional area by layer blending or across vertical columns, column blending, or a combination of layer and column blending.       The presently preferred method of the present invention employs either vertical displacement of a partial vertical column of the silo content to provide a representative mixture in every horizontal cross-section in order to reduce the number of necessary recycles to a minimum or substantially simultaneous multilevel displacement, with subsequent uniform discharge over the whole horizontal cross-section of the silo to remix material that may have been segregated during the filling or recycling.  In either event, the presently preferred univeral blending system includes a blending bottom whose construction gives the opportunity to make a choice of (1) discharge over only a partial area of the outlet area; (2) uniform discharge over the whole outlet area; or (3) predictable discharge velocity distribution over the outlet area.

Title: Decolorizable imaging system including a bleachable or leuco dye and a nitrate salt
Inventor: WINSLOW JOHN M
IPC: G03C1/52

Granted: 1983-10-11
Abstract: DECOLORIZABLE IMAGING SYSTEM The cost of conventional silver halide imaging technology has increased dramatically with the rising cost of silver. It would therefore be desirable to remove the silver from such imaging materials. Many replacement systems for silver tend to be complex without providing equivalent sensitometric results to silver halide systems. A novel imaging system comprising a binder containing nitrate salt and bleachable dye has been found to be an effective thermographic imaging system.

Abstract: ABSTRACT OF THE DISCLOSURE     The goggles have two eyepieces connected by an elastomeric strap forming a nosepiece, the length of which is adjustable by loosening a pair of adjustment screws.  Each eyepiece has an upper contour portion having a smooth incurve to conform to the upper eye socket.  The lower portion of each eye-piece has a smooth incurve with an excurvation in the vicinity of the nose-piece to conform to the lower eye socket.  Each eyepiece flares outwardly to form a widened eye socket contacting surface.  Each of these surfaces slopes radially outward of the eyepiece and toward the front thereof.  In this manner, when worn, the surfaces produce a radially outward pressure on the eye socket and require only a minimum layer of form padding to insure a watertight seal.  The goggles are also equipped with an elastic head strap attached to a plastic hook end which fits into an aperture on one of the eyepieces for easy attachment thereto.

Abstract: Abstract A mixer-pump has a rotor shaft with a set of pins intermeshing in pins extending inwardly from a cylindrical stator to mix together materials flowing axially through the cylinder.  The pins are generally cylindrical in shape except for a set of pins on the rotor shaft designated pumping pins which are half cylindrical with their flat faces oriented to impart a longitudinal direction of travel of materials through the cylinder.  Flow throughput is still further enhanced by a set of axially positioned vanes extending from the housing inwardly toward the rotor shaft with curved ends forming a scoop to receive materials being given a rotary flow component about the shaft by its rotation and convert the flow direction to an axial flow path.

Abstract: MULTIPLE DATA RATE DIGITAL SWITCH FOR A TDMA COMMUNICATIONS CONTROLLER                      Abstract A multiple data rate digital switch for a TDMA communi-cations controller is disclosed which can service a plurality of input/output ports having many different data rates on a time divided basis, either between ports connected to the same controller or between ports connected to different, geographically remote con-trollers.  A transmit burst buffer and a receive burst buffer are connected between the local ports and a TDMA communication link and an intranodal buffer is con-nected between local ports.  A11 three buffers are accessed by a switch control memory which stores ni control words for each of the ports which are scanned m times per TDMA frame, there being a frame rate of f frames per second.  Thus, the ports are selected and their data is buffered at a rate Ri which is equal to the product of ni times m times f.  In this manner, ports having a variety of data rates can be serviced on a time interleaved basis with maximum connectivity.
