Abstract: TITLE:  Anaerobic Method for Preserving Whole Blood, Tissue and Components Containing Living Mammalian Cells ABSTRACT OF THE INVENTION   An Anaerobic method for preserving mammalian blood, mammalian tissue or living-cell containing components of either in a state of suspended animation, and the products of that method, are described.  The method involves adding the substance to be preserved to a receptacle containing anticoagulant and low molecular weight hydroxyethyl starch, hydroxypropyl starch or polystarch containing from about 450 to about 1000 glucose units per molecule, mixing well, while maintaining the temperature in the range of from about 35° to about 40°F., and storing the resulting mixture at the same temperature.  In a preferred embodiment which preserves blood, tissue or a component indefinitely, the structure is lightly crosslinked (i.e., about 1 cross-link per 50 glucose units) with the aid of a water-soluble cross-linking agent of the acrylamide type, to form a gel structure.    When it is desired to use the preserved material, the swelled starch derivative may be liquefied, or the gel may be broken, by an isotonic wash or by microwaving.  The bulk of the starch derivative and any acrylamide type crosslinked present are removed by filtration, whereupon the preserved material may be used in the same way as a freshly collected substance containing living cellular material might be used.

Abstract: ABSTRACT OF THE DISCLOSURE         A furnace having a primary heat exchange unit also providing a combustion chamber, a secondary heat exchange unit connected by an upper crossover conduit to the primary heat exchange unit, and a tertiary heat exchange unit con-nected by a lower V-shaped crossover conduit to the second-ary heat exchange unit.  A third crossover conduit connects the V-shaped crossover conduit with the primary heat exchange unit.  A fly ash removal screw is located in the V-shaped crossover conduit to move fly ash therefrom through the third crossover conduit back into the primary heat exchange unit to an ash depository for removal there-from.  Vibrating means are provided between the secondary and tertiary heat exchange units to vibrate the walls thereof and dislodge clinging fly ash so that it falls into the V-shaped crossover conduit for removal by the screw conveyor.  A burner assembly of the furnace includes a combustion air housing carrying a circular, stationary grate with an annular valley for carrying fuel during combustion.  A central opening is connected to a fuel conveyor for introduction of fuel to the grate through the lower portion of the housing.  Combustion air intro-duction conduits on the housing are remote from the fuel introduction passages and introduce air under pressure at the lower portion of the grate.  An agitator and discharge ring is provided on the grate and is rotated on the grate by a suitable drive sprocket mechanism to agitate the fuel for more complete burning thereof and to remove burned ash.  A horizontal burner plate is supported by a plurality of legs connected to the agitator and dis-charge ring over the grate to promote more complete com-bustion of the fuel.

Abstract: ULTRASOUND TISSUE PROBE LOCALIZATION SYSTEM     Abstract of the Disclosure A novel pulse-echo ultrasound imaging system is disclosed comprising at least three transducers.  A first external scanning transducer images a selected scan area of body tissue by pulsing that area with ultrasonic waves.  Two additional detector-transducers are disposed at distinct locations on a probe, such as a biopsy needle, which is in-serted into the body in the vicinity of the scan area.  By determining the sequence of wave front arrivals at the detectors-transducers, the relative location of the probe with respect to the scan area is readily determined and in-dicated.  Either the scanning transducer or the probe may then be maneuvered in response to such indication to ensure that the probe tip is properly positioned relative to the scan area.

The method and chamber direct whole blood into the chamber from the first side (131, 132; 181, 182, 183) thereof at a point between the bottom and top of the chamber.  Heavier particles such as red blood cells are directed downwardly and outwardly along the outer wall surface (160) toward the lower bottom corner (190) of the chamber.  At the same time, plasma is directed up-wardly along the inner wall surface of the chamber so that there is separation of white blood cells, particularly granulocytes, from the whole blood which are directed with the plasma, toward and out the first outlet (122) from the chamber.

Abstract: ABSTRACT OF THE DISCLOSURE           An injection pump assembly for an internal combustion engine includes a pump housing having at least one mounting bore extending thereinto from a surface thereof, and a respective injection barrel located at a mounted position in each mounting bore for housing a respective pumping piston in one end thereof and a respective valve means in the other end thereof.  Each injection barrel includes at least one annular seat formed in the external periphery thereof and a respective annular seal in the seat.  The annu-lar seal normally projects radially outward beyond the external periphery of the injection barrel axially adjacent to the seat when uncompressed.  The annular seal is compressed by radial engagement with the wall of the mounting bore when the injection barrel is in the mounted position in the bore.  In accordance with the invention, the mounting bore is chamfered to a di-ameter sufficiently small for engagement with the annular seal when the injection barrel is at the mount-ed position.  The diameter of the bore between the housing surface and the chamfer is always greater than the diameter of the annular seal when uncompressed, thereby to prevent shaving the annular seal during axial displacement of the injection barrel into or out of its mounted position.

Abstract: Abstract of the Disclosure A  tri-state  driver  circuit  10  for  selectively driving a node of a device under  test by applying and switching  between  two  reference  voltages,   and   for selectively operating at a high impedance output state. Two current sources 16 and 18 provide a bridge current that flows through a diode bridge 20 to establish, at nodes A and B, voltages that equal two reference voltages, DRH and DRL.  The  diode  bridge  includes  resistors  R11 and  R16 across which the bridge current is switched to accommodate small voltage swings, and also includes clamp diodes CR3-6 to accommodate large voltage swings.  A current switch 22 controls  the  direction  of  the  bridge  current  and  the selection of which of the two reference voltages appears at node A.  A current sink 36, 38, and 40 monitors the average voltage of the diode bridge and adjusts it to equal the average of the two reference voltages.  A feedback circuit 42, 44, and 46 monitors the higher of the voltages at nodes A and B and adjusts it to equal the higher of the two reference voltages.  A transistor-diode bridge 48 operates as a buffer to generate an output signal equal in voltage to the voltage at node A.  A switch controller 50 switches the transistor-diode bridge to a high  impedance output state when so selected.
