Abstract: MIXED THICKNESS SHEET SEPARATOR AND FEEDER                  ABSTRACT OF THE DISCLOSURE           A sheet separating device for mechanically feeding single sheets from a magazine having a stack of intermixed sheets of different thicknesses.  The apparatus includes a conveyor assembly having an endless belt provided with integral feed pads for successively contacting and transporting sheets from the stack.         A feed limiting barrier directs movement of the sheets toward a pair of discharge rollers which rotate in a direction for advancing the movement the sheets.  A separator roller mounted in confronting, overlapping relationship with the discharge rollers rotates in a direction opposing forward movement of the sheets to prevent passage of more than one sheet between the separator and discharge rollers.         The conveyor assembly is spring-biased and swingably displaceable with respect to the separator roller for variable clearance in order to accommodate sheets of different thicknesses Additionally, the discharge rollers are urged into contact with idler rollers to automatically compensate for wear.  A sheet limit stop spaces the sheets with regard to the belt and feed pads in order to relieve intersheet pressure and to minimize the adhesion between adjacent sheets during engagement by the feed pads.

Abstract: PROCESS FOR DIRECT ELECTROCHEMICAL RECOVERY           OF COPPER FROM DILUTE ACIDIC SOLUTIONS          Abstract of the Disclosure The invention relates to the direct electrochemical recovery of copper from dilute acidic solutions of pregnant or copper bearing liquor from copper leaching systems.  The pH of the liquor is maintained below 2.2.          The liquor is introduced into an electrolytic cell having a cathode of an electrically conductive porous material and an anode.  A current of 3 to 100 amps per square foot of cross-section is applied to the cathode and the liquor is flowed through the cell at such a rate that virtually all the copper in the liquor is collected at the cathode.   The copper is then recovered from the cathodic material.          This method allows the utilization of a recovered barren (decopperized) leach solution in a recycling process for recovering copper from sources such as mine waste dumps or in-situ mined copper.

Abstract: GAS DISCHARGE DISPLAY PANEL FABRICATION               Abstract of the Disclosure An in situ process is disclosed for fabricating gas discharge display panels in a sequential seal, bake-out and backfill mode of operation.  The single thermal cycle process involves placing unassembled panel parts in a controlled gas ambient furnace system with required seal frame, evacuating said furnace and backfilling with an appropriate ambient atmosphere to an appropriate pressure while heating the furnace.  During the heating, the furnace is repeatedly evacuated to moderate vacuum and refilled to some predetermined pressure.  The furnace is heated to just above the glass transition temperature of the seal frame in this evacuate-refill mode, then held for some time to achieve outgassing of both panel parts and furnace chamber.  Thereafter, the furnace chamber is refilled to one atmosphere and further heated to complete the sealing of the panel.  The panel is then cooled to approximately 300°C, still under one atmosphere, after which the evacuate-refill cycle is continuously repeated as the temperature is lowered down to the temperature of tip-off using the refill gas for the pressurization.  The panel is refilled to an appropriate pressure at elevated temperature such that at room temperature the pressure is the desired pressure and the panel is tipped off.  The process of successive evacuations and backfillings at the appropriate portions of the cycle are highly desirable for cleaning of the panel parts via contaminant dilution.

Abstract: ABSTRACT OF THE DISCLOSURE       A flooring tile made of rubber or plastics material is generally rectangular or square and has a plurality of circular bosses in relief, the bosses are arranged in rows parallel to the side edges of the tile, bosses of each row being offset in relation to bosses of the adjacent rows by half the separation between adjacent bosses in a row so that the rows of bosses can be spaced more closely together.  The side edge of the tile have a sinuous outline following the outline of the adjacent bosses; the outline of the two opposite edges which run parallel to the rows of bosses is less pronouncedly sinuous than that of the two opposite side edges which run transverse to the rows of bosses.          Opposite parallel side edges are complementary so that like such tiles can be fitted together, interlocked against relative slippage, and the junction between adjacent tiles is inconspicuous since the line tends to be obscured by the bosses.

The crushing rolls have cylindrical surfaces defining pyramid shape indentations arranged in a diamond pattern and sur-rounded by protuberant cutting edges.  Drive means are coupled to the cutter assembly and the crushing rolls for rotating same.  The crushing rolls are rotated in opposite directions so that grain from the hopper outlet enters the nip to be crushed and passed through the crushing rolls.  A conveyor removes the crushed grain from below the crushing rolls.          The crushing rolls include a driving roll, and a driven roll, the latter roll being driven by frictional contact between the adjacent surfaces of the respective rolls.
