Abstract: ABSTRACT OF THE DISCLOSURE           Spherical polymer particles may be produced by dispers-ing water-soluble monomers or polymers in a hydrophobic solvent, such as toluene or chloroform.  These solvents, however, have a dewatering effect on sensitive biomaterials if these are simulta-neously enclosed in the polymer particles.  The present invention shows that it is possible to enclose sensitive biomaterials selected from plant cells, animal cells, bacteria, algae and fungi, in spherical polymer particles with retained viability and growth capacity if a suitable combination of polymer and dispers-ing medium is used.  The polymer is selected from agar, agarose and fibrinogen.  The dispersing medium is selected from paraffin oil, soybean oil, liquid silicone, phthalic acid dibutyl ester and tri-n-butyl phosphate.

Abstract: Abstract: "Method and device for remote tissue identification by statistical modeling and hypothesis testing of echo ultrasound signals".     For remote identification of tissue types the scattering of ultrasound energy from living tissue is modeled as an autoregressive or autoregressive moving average random process. Autoregressive or autoregressive moving average models of candidate tissue types are generated from pulse-echo data that is known to come from that particular tissue type. Kalman prediction error filters (220) are used for each candidate tissue type to generate estimates of the probability lnp(Zn/Hi) that an unknown pulse echo signal belongs to the class generated by that tissue type (i). Unknown pulse-echo signals are filtered in a specific Kalman filter (220) to test the hypothesis that the unknown signal belongs to the class associated with that particular Kalman filter.

Abstract: ABSTRACT OF THE DISCLOSURE An  elevator  system,  and method of monitoring same,  which includes a plurality of elevator cars under the group supervisory control of at least first and second processors, which all share a common memory over a system bus.  The first processor periodically monitors its own status, and it sets a predetermined location of the shared memory each time it finds its status to be normal.  The second  processor  periodically  checks  the predetermined location,  and upon finding it  set,  it  resets  it.  The second processor also monitors its own status.  The second processor  triggers  a  retriggerable hardware  timer  each time it determines that the first processor and itself are both operating normally, with the trigger rate preventing the timer from reaching the end of a predetermined timing period.  When the second processor finds the  status  of either processor to be abnormal, it terminates its trig-gering of the timer.  The timer then provides a signal at the end of its timing period,  which reinitializes both processors.

Abstract: ABSTRACT          A new type of passive trihedral corner reflector is described which rotates the polarization of a reflected microwave beam by 90° and thereby permits a reflected radar beam to be more easily distinguished by the interrogating radar system from the random reflections from nearby objects, i.e., clutter.  Rotation of the incident beam is provided by locating a polarizing or "twist" grid of closely spaced thin parallel wires spaced above one conducting surface by air or by a dielectric to give an electric spacing from the surface of about 0.25 ? .  The spacing of the wires is less than 0.25 ? so that the wires constitute a reflecting surface for signals polarized parallel to the wires.  The reflector can have triangular or square sides which are mutually orthogonal.  In a preferred embodiment the reflector is tipped forward by 35° from a reference horizontal plane and tilted clockwise in a vertical reference plane by 15° to optimize reflections.  The reflector has particular application to navigation systems, especially to maritime navigation systems.

Abstract: ABSTRACT          A fastener assembly has two sets of fastener profile elements for a reclosable bag especially adapted for mutually facilitating alignment and interlocking closure interengagement of said fastener profile elements response to closing pressure applied from outside of the bag toward the fastener assembly.        Further, the fastener assembly is so constructed that a lower portion of the fastener assembly effectively resists opening separation from the interlocking interengagement thereof by separating forces exerted on the wall panels of the bag from inside of the bag body, while the upper portion of the fastener assembly is adapted to be relatively easily separated by pulling apart pull flanges extending thereabove, and such pulling apart of the pull flanges sequentially thereafter being adapted to pull apart the lower portion of the fastener assembly for access through the mouth of the bag into the interior of the bag.

Abstract: MUZZLE BRAKE     ABSTRACT          The  muzzle  brake  disclosed  is aimed  at  being  more effective  in reducing the recoil of a gun.  The end  of the barrel is provided with a long,  narrow chamber (30) which  has  the effect of containing  the  muzzle  gases against  radial  expansion,  and causing them to  emerge forwardly   as   a  jet.   The   jet   intensifies   the concentration  of the gases against the back (23) of the reaction plate (20).  The brake is open backed,  so that the  jet  draws  in atmospheric  air.  This  promotes  a vigorous explosion of the remaining unburnt  propellant.          The  gases  that travel rearwardly after  the  explosion exert  only a small rearward (recoil worsening) force on the gun.  A deflector (52) deflects the gases away  from the gun operator.

Abstract: ABSTRACT     Ruthenium-promoted cobalt carbonyl catalysts which have been further promoted with an organophosphite effectively catalyze the dealkoxyhydroxymethylation of aldehyde acetals to form glycol monoethers.     Methylal, for example, may be reacted with syngas, i.e., CO and H2, in the presence of these phosphite-ruthenium carbonyl-promoted cobalt catalyst systems to form the monomethyl ether of ethylene glycol.     Cycloalkyl- and aryl-acetals, as well as alkyl-acetals, may likewise be reacted with syngas in the presence of these phosphite-ruthenium carbonyl promoted cobalt carbonyl catalysts to form the corresponding ethylene glycol monoether.  The process may advantageously be carried out with high yields and selectivities in the presence of a polar or non-polar organic solvent in combination with the catalyst systems of this invention.     The invention is also directed to the organophosphite ruthenium-promoted cobalt carbonyl catalyst systems per se.
