Abstract: ABSTRACT OF THE DISCLOSURE            PROCESS FOR THE SEPARATION OF AMIDES FROM NITRILES           A process for the removal of impurities comprising amides from a solution comprising nitriles and the impurities.  A reaction mixture is formed which includes the solution, a layered mineral comprising aluminum silicates having exchangeable alkaline or alkaline earth cations on the surfaces of the layers and an acid which has an acid strength sufficient to protonate the amides at amide protonation conditions, but in which the solubility of the salt of the acid and exchangeable cation at those conditions is such that the equilibrium of the protonation reaction is substantially in the direction of the amides remaining in a protonated form.  The water content of the reaction mixture must be less than about 0.5 wt. % for substantially all of the reaction time.  The reaction mixture is maintained for a sufficient time at the amide protonation conditions for protonation of the amides and exchange of the protonated amides and exchangeable cations to occur, the protonated amides adhering to the surfaces of the layers.  Nitriles having a reduced content of impurities may then be separated from the reaction mixture.  Effective means of separation are rotating drum vacuum filters, preferably two in series.

Abstract: SURGICAL STAPLING INSTRUMENT WITH JAW LATCHING MECHANISM AND DISPOSABLE STAPLE CARTRIDGE            Abstract A surgical stapling instrument suitable for performing a gastrointestinal anastomosis is provided.        The stapling instrument includes a pair of elongate jaw members, one of which supports a staple cartridge adapted to receive at least two laterally spaced longitudinal rows of staples, and the other provided with an anvil adapted to form the staples.  A pusher bar and knife blade assembly is slidable longitudinally relative to the jaw members to sequentially drive the staples from the cartridge and form the staples against the anvil to produce a pair of laterally spaced rows of formed staples in tissue gripped between the jaw members and to cut the tissue along a line between the staple rows.  A latching mechanism is arranged to latch the jaw members together at an intermediate position therealong adjacent to the staple cartridge and the anvil.  The latching mechanism is operable to a partially latched position in which the jaw members are loosely connected together to permit the staple-cartridge and anvil to be adjusted in position on the tissue without disconnecting the jaw members from each other.  A cam mechanism is provided for urging the jaw members apart at a position remote from the latching mechanism to resist the forces exerted on the staple cartridge and anvil when the pusher bar and knife blade assembly is actuated to staple and cut the tissue gripped between the jaw members.  The cam mechanism is initially held in an inoperative position by a first set of retainer arms and subsequently held in an operative position by a second set of retainer arms when the pusher bar and knife assembly is actuated.  Preferably, the staple cartridge is disposable to allow the stapling instrument to be reused for surgery on the same patient.

Abstract: RAPPELING DEVICE            Abstract of the Disclosure The present invention is comprised of three integral eyes joined end to end for receiving a doubled back segment of a line such that the line becomes wrapped around the device to frictionally slow the rate of descent of the device, and a person attached to it, down the line.  The line can be attached to the device in several manners, all of which include passing the doubled back line segment through one or more of the eyes and then wrapping it around the device so that it cannot be pulled back through the eyes.  In addition to being easily attached to the line intermediate its ends it attaches symmetrically to the line so that the line does not hock as it is played through the device.  By turning the device upside down and attaching it to a fixed anchor it can be used to lower a load attached to one end of the line.

Abstract: ABSTRACT          A semiconductor chip package configuration and a method are disclosed for facilitating testing of the chip package and mounting of the chip package on a substrate by forming one or more lead alignment bars in interconnecting relation with adjacent leads on the chip package, the lead alignment bars being formed from a material providing electrical isolation between leads during testing of the chip package and for providing physical spacing between the leads both during testing and later mounting of the chip package on the substrate so as to prevent adjacent leads from inadvertent contact.  Preferably, the lead alignment bars are formed from a high resistivity material selected to provide sufficient conductivity between the interconnected leads for minimizing electrostatic discharge conditions therebetween, the material being sufficiently non-conductive to permit functional and dynamic testing of the leads.  After testing of the chip package, it is mounted on the substrate with the interconnecting lead alignment bars then being removed to facilitate subsequent operation of the chip package.

Title: Removal of impurities from a gas
Inventor: MITSUGI MIURA
IPC: B01D47/02
Filed: 1968-06-17
Abstract: The stream of gas is passed in a cyclic manner downwards in a first treatment zone in which the heavier particles become deposited at the foot of the walls, while the partly purified gas from a second treatment zone is directed radially towards the inside of the cyclically descending gas in the first treatment zone. The cyclically downward moving gas in the second zone on reaching the bottom is atomised with fluid onto the top of the upper part of the second treatment zone forming a miol which tends to trap solid impuritis from the ascending gas and sink under its own weight to the bottom of the second zone and from there into a zone where the impurities are removed. The gas, freed from impurities rises into the second zone and from there outwards.

Abstract: The unexpected synergistic interplay between lymphokines and dsRNAs which dramatically reduces the necessary dosages of lymphokines, especially IL-2, and simultaneously widens their therapeutic range in the treatment of various types of cancers, viral disorders or other body conditions characterized by disregulated immune states (e.g., autoimmune diseases). Specific combinations of dsRNA plus IL-2 significantly increase survival in human melanoma-bearing animals in part because of augmentation by dsRNA of lymphokine activated killer cells (LAK) which are first formed in response to IL-2 exposure.
