Abstract: AIR PURGE UNIT FOR AUTO TRANSFUSION APPARATUS     ABSTRACT        An air purge unit for an auto transfusion device is provided wherein a housing having a passageway therein is mounted on the top wall OF a blood collection chamber.  A filter having pore sizes smaller than the size of red blood cells is disposed within said passageway together with an umbrella valve and a oneway flap valve which will permit the passage of air from within the collection chamber through the valves to a source of suction or to atmosphere.    When the air is purged from the interior of the collection chamber, the red blood cells will block the filter and pre-vent the further passage of fluid therethrough.

Abstract: TITLE Apparatus for cutting  openings in pipes ABSTRACT OF THE DISCLOSURE.          An apparatus for cutting openings in pipes of cuttable material, in particular in plastics drainage pipes  has at least one cutter head carrying at least one cutter, the cutter head rolling at least in part on the periphery of the pipe and being positively driven for this by means of a planetary gear.  By virtue of this, the cutting edge of the cutter moves around the pipe in an epitrochoid.  The cutter head is provided with ridges engaging in transverse corrugations in the outer wall of the pipe.            In order to be also able to cut openings in pipes formed at least in part with annular corrugations over their periphery, at least the cutter head is provided with helically extending ridges and the at least one cutter is disposed parallel to these ridges.

Abstract: ABSTRACT OF THE INVENTION    A closed, air-free blood oxygenator assembly having integrated into one self-supporting unit a rigid-shell blood reservoir having an easily visible, concavity which is closed by an attached expansible, flexible membrane which overlies the concavity and forms a variable volume liquid and air-tight blood reservoir, and an attached blood heater, and a hollow fiber membrane oxygenator. The assembly stores, heats, oxygenates and purifies blood by passing oxygen through the lumens of a mat of small diameter gas-permeable hollow fibers supported on a cylindrical core as blood flows over the outside sur-faces of the fibers in a small, easy to use, safe, inte-grated unit which avoids blood contact with ambient air as blood circulates through the assembly during surgery.

Abstract: 6"-DEOXYDIBEKACIN, 4"6"-DIDEOXYDIBEKACIN AND 1-N-AMINOACYL DERIVATIVES THEREOF,AND THE PRODUCTION OF THESE NEW COMPOUNDS            ABSTRACT OF THE DISCIOSURE       New compounds, 6"-deoxydibekacin, 4",6" dideoxy~ dibekacin, 1-N-(L4-amino-2-hydroxybutyryl)-6"-deoxy-dibekacin and 1-N-(L-4-amino-2-hydroxybutyryl)-4",6"-dideoxydibekacin are now produced semi-synthetically from dibekacin, i.e. 3',4'-dideoxykanamycin B.  These four new compounds are each useful as an antibacterial agent. Production of 6"-deoxydibekacin or 4",6"-dideoxydibekacin is made by removal of the 6"-hydroxyl group or by removal of the 4"- and 6" hydroxyl groups from an amino-protected and hydroxyl~protected derivative of dibekacin.  Production of 1-N-(L-4-amino-2-hydroxybutyryl)-6"-deoxydibekacin or -4",6"-dideoxydibekacin is made by acylating the 1-amino group of 6"-deoxydibekacin or 4",6"-dideoxydibekacin with the L-4-amino-2-hydroxybutyryl group, or alternatively by removal of the 6"-hydroxyl group or the 4"- and 6"-hydroxyl groups from a known compound, 1-N-(L-4-amino-2-hydroxy-butyryl)-dibekacin.

Abstract: Abstract of the Disclosure A fluid transfer system including a cap member having a first fluid transfer member therein and being removably mountable on a second fluid transfer member.  Cooperating lugs and slots formed by the cap member and second member lock the two members together when the cap is placed on the second member and rotated relative thereto.  A resilient annular gasket is disposed between the second member and cap member and surrounds the liquid passageway therethrough to prevent leakage.  The second member and cap members form an annular space on one side of the outer peripheral portion of the gasket, and an annular bead presses against the other side of the outer peripheral portion of the gasket so that the bead bends that portion of the gasket into the annular space to effect a liquid-tight seal on both sides of the gasket. In the preferred embodiment, the locking lugs are formed on the second member which fits inside the cap member, and the locking slots formed by the cap member extend radially through the wall of the cap member so that the cooperating lugs on the body member are visible through the slots.  The slots form cam surfaces which force the cap member tightly onto the second member, and locking notches adjacent the ends of the cam surfaces for holding the cap member in a predetermined locked position.  The ends of the notches adjacent the cam surfaces are tapered in the direction of the cam surfaces so that the application of a turning torque to the cap is sufficient to disengage the locking notches from the lugs, thereby facili-tating disassembly of the cap.  In one embodiment, the fluid transfer system comprises a spray nozzle assembly in which the first fluid transfer member is a spray tip seated in the cap, and in alternate embodiments, pipe coupling assemblies are disclosed wherein the first and second fluid transfer members are pipe sections.

Abstract: ABSTRACT OF THE DISCLOSURE          A  piston is manufactured by incorporating a reinforcement which  is formed at least in part by a fibre material  and which   is   so  non-uniform  as  to   provide   differing characteristics  in  the cast  piston  in    predetermined differing  regions  of  the  piston.    For  example,  the volumetric  density of the fibres may be different in  one region  of  the  reinforcement as  compared  with  another region in order to produce a more resistant region in the cast  piston.    Additionally  or     alternatively,   the reinforcement  may  hold  finely divided  materials  which combine  with the piston material during casting  to  give improved   properties.    Examples   of   this   are   the incorporation of particles of silicon,  silicon carbide or silicon nitride to improve   wear and/or the incorporation of  molybdenum  disulphide and tungsten     disulphide  or graphite to improve lubrication.

Abstract: ABSTRACT          The invention provides an improved cellulosic ester or ether product with a degree of ester or ether substitution of between 2 . 0 and about 2 . 9 which is derivatized or further reacted by reaction with an acryl-amide reactant to provide pendant acrylamide functional-ity or substituents at a degree of substitution (D.S.) of at least about 0.05 (preferably from about 0.05 to about 0.5) and to thereby provide a polymerizable organic sol-vent-soluble product which is insoluble in water and copolymerizable with vinyl monomers. The product is conveniently prepared by reacting said cellulose ether or ester derivative with a catalyst and the acrylamide reactant at a pH of from between about 4.2 and about 4.5. The reaction is carried out at a temperature be-tween 80°C. and 120°C. for from one-half to three hours, while removing the water of reaction. The resulting acrylamide functionality-containing cellulose ester or ether product typically contains unreacted, residual hydroxyl groups in an amount corresponding to a hydroxyl D.S. of from about 0.05 to about 0.95.

Abstract: ABSTRACT OF THE DISCLOSURE           A protective relay having an operational boundary matched  substantially  to  the  output  performance  limit characteristics of a generator to enhance the protection thereof  is disclosed.  The protective  relay generates a signal representative of a discriminating impedance based on measurements  of  the generator's terminal voltage and current.  The relay utilizes  two pairs  of predetermined values which characterize in part the generator's output performance  limit  curves.   Two  corresponding  pairs  of vector signals are generated by the relay based on their respectively corresponding pairs  of predetermined values and  the  generated discriminating  impedance  signal.  The angles between the vector pairs are measured by the relay and are compared with predetermined angle values which also represent  in  part  the  generator's  output  performance limitations.  Leading and lagging conditions of at least one of the vector  pairs  affects  the  selection  of  the predetermined angle value used in the comparison with the measured ankle associated therewith.  Should the results of the  comparisons  indicate  that  the  measured  angles  are beyond their respective predetermined angle values,  then the protective  relay  signifies that an unsafe generator operating condition exists.
