Abstract: RECOVERING COPPER FROM CHALCOPYRITE CONCENTRATE           ABSTRACT OF THE DISCLOSURE    A process and system are provided for recovering copper from chalcopyrite concentrate.  The chalcopyrite is ground to a mean particle size of about 1.5 - 5 microns. The ground chalcopyrite is then divided into a first stream and a second stream.  The first stream is leached in a leach solution containing at least about 100 gpl sulfuric acid and about 10 - 30 gpl ferric iron to produce a copper sulfate solution containing about 40 - 75 gpl dissolved copper and less than about 5 gpl ferric iron. The second stream of ground chalcopyrite is combined with the copper sulfate solution and with sulfur dioxide such that the combination reacts to precipitate dissolved copper from the copper sulfate solution as simple copper sulfides and to produce a liquor containing dissolved ferrous iron.  The simple copper sulfides are then separated from the ferrous iron liquor.  Sulfuric acid is added to the ferrous iron liquor to precipitate the ferrous iron as ferrous sulfate and to produce a recycle solution containing about 400 - 600 gpl sulfuric acid. The recycle solution-is added to the leach solution. Copper is recovered from the simple copper sulfides.     Case No. 971

Abstract: ABSTRACT OF THE DISCLOSURE    A double action mechanical press, especially for performing a blanking operation and a forming operation on each cycle thereof, having a first slide and a second slide, wherein the slides have separate strokes.  The slides are reciprocated by means of a crankshaft and connecting rod assembly comprising a single crankshaft and a plurality of connecting rods wherein the throws of the crankshaft can be differ-ently dimensioned and angularly offset relative to each other so as to provide different stroke lengths for the slides and to cause one slide to lead the other.  A guide bushing assembly is connected to one of the press slides, and a blanking punch is received in the guide bushing for reciprocating movement relative to the bushing along the same direction of reciprocating movement as the slides.  A preloaded antifriction bearing is positioned between the punch and bushing assembly, and serves to maintain the proper clearance between the punch and the corresponding cutting edge on the lower die half.  A forming die is received in the guide bushing assembly for reciprocating movement relative thereto and is connected to the other press slide.  The other portion of the punch is formed as a piston and is urged downwardly by pressurized air.  The travel of the punch against the pressurized air enables the punch to abut the top of the strip material until the blanking slide strikes it and causes it to blank out the part.  Meanwhile, the forming die draws the blanked out part, which is continued to be held by the pressure of the punch against the liftout ring.  Thus, the action of the floating punch simulates the dwell provided by a cam driven punch.

Abstract: Abstract of the Disclosure A single print element of a typewriter has the characters thereon impact a record sheet at one of two velocities depending on the area of coverage of the character. Each character on the print element is selected for printing by movement of one of a plurality of interposers with each interposer selecting two characters. One of the two characters is selected by movement of the interposer when a pair of operatively connected shift layers is not depressed while the other of the characters is selected by the same interposer when the shift levers are depressed. A vane, which extends between the shift layers and is pivotally connected thereto, is disposed in the path of movement of all of the interposers. The vane has an opening for each interposer when the print element is to impact the record sheet at the higher velocity so that the vane is not engaged by the interposer during movement  of the interposer. If the print element is to strike the record sheet at the lower velocity, then the vane has a portion for engagement by the moving interposer. The vane has a first group of openings and portions for cooperation with the interposers when the shift layers are not depressed and a second group of openings and portions for cooperation with the interposers when the shift levers are depressed. When the vane is engaged, the print element strikes the record sheet at the lower velocity.

Abstract: DYNAMOELECTRIC MACHINE BEARING      ABSTRACT OF THE DISCLOSURE                    A bearing fail-safe type dynamoelectric machine is provided with first and second bearings at one end of the machine.  The machine is shown as a vertical shaft machine with both bearings capable of carrying the longitudinal thrust due principally to the weight of the rotor and shaft. The first bearing is mounted in a seat in the frame and ro-tatably journals the shaft under normal running conditions. The second bearing is adjacent to the first and positioned above it, and is in an idling condition or nonload-bearing condition by being radially and longitudinally spaced from the seat in the frame.  If the first bearing should fail, then the shaft will drop slightly, due to gravity and applied external forces, and the second bearing will become enabled, rotatably journaling the shaft.  This will establish a fail-safe bearing construction in the dynamoelectric machine.  The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: ABSTRACT OF THE DISCLOSURE           A disposable surgical stapler has a tubular pusher movable in a tubular housing, a central rod movable in the pusher and a handle pivotally mounted on the housing, and extending into slots in the housing and pusher for moving the pusher.  A staple carrying assembly on the housing is activated by the pusher to urge staples against an anvil on the rod.  The position of the rod relative to the housing is determined such that the anvil and the assembly are properly spaced apart for fastening tissue between them.  A groove in the rod is located, so that when the anvil and the assembly are thus properly spaced apart the pusher slot is laterally aligned with the rod groove and an end of the handle can move into the groove and against an end of the pusher slot to move the pusher to activate the assembly.

Abstract: ABSTRACT OF THE DISCLOSURE    The dot matrix plasma display of the present invention comprises a plurality of parallel cathode strips mounted on the upper surface of a dielectric substrate.  A glass plate is sealingly engaged over the upper surface of the substrate in spaced relation thereto so as to form an envelope there-between.  The undersurface of the glass plate includes a plurality of anode strips which extend in a direction parallel to one another and perpendicular to the cathode strips located on the substrate below. A dielectric film is printed over the cathode strips and includes a plurality of apertures therein which correspond to the junctures between the anode strips and the cathode strips, these junctures forming a dot matrix.  Ionizable gas is contained within the envelope and is adapted to glow adjacent the junctures of any simultaneously actuated anode and cathode strips.    The method for driving the dot matrix plasma display includes actuating the cathode strips one at a time sequentially. Simultaneously with the actuation of each cathode strip, a pre-selected combination of anodes are also actuated so as to cause the gas to glow adjacent the junctures between the actuated anodes and cathode strips. The cathode strips are scanned at a frequency which to the human eye gives the appearance that they are constantly actuated.

Abstract: Abstract of the Disclosure Railroad spikes and the like are formed by apparatus having a stop contacting and limiting movement of the forward-most end of a heated stock bar.  A bending finger holds the forwardmost end in spaced relation from a stationary gripper die, while a movable gripper die engages the bar and moves it into engagement with the stationary gripper die.  Cutter dies then engage the bar to form a tapered end portion at a predetermined location rearward of the forwardmost end as a head forming die engages the forwardmost end to form a spike head.  The movable gripper die is urged toward the bar with a force which is pro-portional to the force exerted by the head forming die on the movable gripper die.  The finished spike is ejected when it contacts an ejector finger.
