Abstract: Conversion of plutonium nitrate containing americium as a contaminant into plutonium dioxide while concurrently preventing americium contaminant from passing into the plutonium dioxide product. Discontinuous precipitation of plutonium oxalate is effected by maintaining the Pu nitrate-nitric acid solution containing americium in a reaction vessel at 60 DEG -95 DEG  C., adding granular solid oxalic acid or solid ammonium oxalate in freeflowing form substantially free of clusters and lumps in stoichiometric deficiency of up to 7% of oxalic acid for reaction with the Pu in the solution; separating resultant Pu oxalate precipitate into which at least a portion of the americium contaminant has been prevented from entering, and calcining the purified Pu oxalate precipitate to PuO2.

Abstract: An apparatus for peeling off the leading edge of a sheet of paper adhering to a moving transfer image carrier during the process of transferring a powder image onto the sheet. The apparatus includes one stripper member or a plurality such as three stripper members mounted in the vicinity of the transfer image carrier at the side on which the sheet is intended to be detached from the same. The one or several stripper members engage the moving sensitive surface of the image carrier at a balanced extremely low contact pressure and are adapted to be lifted off this surface by a peeled-off sheet of copying material. The strippers are continuously reciprocated in a direction transversely of the transfer image carrier and thereby likewise transversely of the advancing sheet so that the problem of traces that may be engraved into the surface of the transfer image carrier is virtually overcome and the useful life of the image carrier is substantially extended.

Abstract: A method of joining a pair of elongated triangular-shaped pieces together by clamping includes the steps of bringing a pair of opposed face platens together to a predetermined thickness which is the thickness of the ultimately desired composite pair. A sliding edge platen is forced against the pair at a pressure sufficient to cause the two triangular-shaped pieces to slide relative to each other against a fixed edge platen to adjust for width and in order to bring the outer side faces of the pair into a substantially parallel relationship. At the end of the curing cycle the pressure is released from the face platens and sliding edge platen allowing them to move apart to their retracted positions and the composite pair may then be removed from the clamping system. A multi-opening clamping system has a plurality of individual clamping mechanisms mounted about the periphery of a rotating cylindrical frame. Each individual opening is capable of practicing the clamping and joining method as the multi-opening clamping system indexes in a substantially automatic manner. Included as parts of the multi-opening clamping system are a loading station, clamping station, unloading station, and an indexing and locking mechanism. Each individual clamping mechanism is comprised of a pair of axially extending, substantially parallel face platens, one of which is fixed and a pair of axially extending opposed edge platens, one of which is slidably mounted between the face platens. The edge platens are sized according to a predetermined thickness which is the final composite product thickness.

Abstract: A surgical stapling instrument for forming and implanting a staple in the skin or fascia of a patient to close a wound or incision therein. The surgical stapling instrument is intended to be used with a staple carrying cartridge of the type taught in U.S. Pat. No. 4,043,504 and characterized by a staple feeding track containing a stack of staples, a parallel staple forming tack, a longitudinally shiftable feeder actuator operative to cause the bottommost staple of the stack to be shifted from the staple feeding track to the staple forming track and a longitudinally shiftable staple former to implant the staple and form it about an anvil mounted on the instrument. The surgical stapling instrument has a handle portion and a nose portion rotatively mounted in the handle portion and capable of being set and remaining in any rotative position with respect to the handle portion. The nose portion carries the instrument anvil and releasably supports the surgical staple carrying cartridge. The nose portion also mounts a longitudinally shiftable feeder block operatively connected to the cartridge feeder actuator and a longitudinally shiftable driver operatively connected to the cartridge staple former. A trigger is mounted in the handle portion and is operatively connected to the driver to shift the driver to cause the cartridge staple former to form and implant a staple. A feeder pawl causes the feeder block to travel with the driver during the driver's initial travel to operate the cartridge feeder actuator to provide a staple for the cartridge staple former to implant and form.

Abstract: The drug detection device which is composed of a pair of members interconnected together to form an internal enclosed chamber. An elongated swab having an absorbent tip is located within the internal enclosed chamber. One of the members of the housing has attached a pair of separate compartments which are interconnected by a frangible seal and further being interconnected to the internal chamber by a frangible seal. Within each of these compartments there is to be located a different substance and upon breaking of the frangible seal between the compartments, the substances within these compartments are to be intermixed. Upon the breaking of the frangible seal to the internal chamber, the tip of the swab will then become in contact with the intermixed substances. The other member of the housing has attached at its closed end a third compartment and within this third compartment is to be located a third substance. After the tip of the swab has been placed in contact with the drug contact area and caused to come in contact with the first two substances, the tip of the swab is then placed adjacent the third compartment and upon breaking of its frangible seal, the tip of the swab will then be contacted by the third substance. If the tip of the swab was placed in contact with a certain family of drugs, the tip of the swab will then change color. Prior to use of the device of this invention, the pair of members of the device are sealingly closed so as to maintain the device in an uncontaminated condition prior to use.
