Abstract: \     CONTINUOUSLY MONITORING RATIOMETER    ABSTRACT OF THE DISCLOSURE    An analytically significant ratio between time-varying magnitudes of signals is periodically monitored in recurring cycles which are each synchronized with a frequency generator.  During every monitoring cycle, each signal relating to the numerator and denominator of the ratio, is integrated separately for a fixed number of generator cycles.  Thereafter in each monitoring cycle, the output from the integrator of the denominator signal is applied at the input to the integrator of the numerator signal and the time taken by the latter to integrate back to its starting level is measured in proportion to the ratio of the signals.  Either digital or analog time measurements may be utilized and the number of generator cycles over which the ratio is determined may include transition periods between each stage of integration.

Abstract: HIGH SURFACE AREA PERMEABLE MATERIAL               Abstract of the Disclosure Three-dimensional structures providing a plurality of separate interpenetrating, three-dimensional domains or channels or flowpaths, each of said domains or channels or flowpaths being a closed system of connected porosity or permeability and each of said domains or channels or flowpaths being interpenetrating  within said structure, have been prepared.  These structures are prepared from porous permeable precursor materials having a single three-dimensional domain or channel or flowpath as described above.  Suitable precursor materials are provided by the abundant porous carbonate skeletal material of marine life, e.g. the coral Porites skeletal aragonite.  For example, by coating the surfaces of such materials with a liquid material capable of being cured or set to a solid, followed by curing or setting and dissolution, e.g. chemical etching, of the coated skeletal material, there is produced a three-dimensional structure in accordance with this invention possessing two separate interpenetrating, three-dimensional domains or channels or flowpaths defined by the residual cured or set coating material.  The resulting structure of this invention can be adapted such that a fluid can be applied to one side or face of the structure to flow into and out of such structure via only one of said channels or flowpaths and when so adapted can be employed in apparatus for the treatment or handling of one or more of the fluid streams flowing therethrough.

Abstract: Abstract of the Disclosure A method for forming a colored image in a limited area of a vision-corrective soft contact lens. In one method, the lens is soaked in a diazonium salt and then exposed to actinic light through a mask which transmits light only to the non-image area of the lens.  Then, the unexposed image area is developed by contact with an azo coupler.  In a second method, the diazonium salt is soaked in a gel relief of the desired image configuration and contacted with the lens.  The image is developed by soaking in the azo coupler.  In a third method, the diazonium salt, azo coupler, and a coupling inhibitor (a pH reducing agent) are premixed and applied by the gel relief.  The image is then developed by raising the image pH level as by contact with ammonia gas. Also, apparatus for precisely contacting the lens with the gel relief image.

Abstract: ROUGHNESS SENSOR            ABSTRACT OF THE DISCLOSURE       A roughness sensor for measuring cycle-to-cycle decreases in engine speed comprises engine-event responsive flip flop means for controlling the alternate store-up and subsequent count-down of contents into a first storage means simultaneously with the alternate count-down and the store-up of contents into a second storage means. The storage means feed respective first and second comparators that produce respective first and second output pulses the widths of which are determined by the interval between the time a corresponding storage means is counted down to its starting value and the time of the next flip flop transition.  A raw roughness output pulse in the form of just one but not both or neither comparator output pulses is passed by exclusive OR logic means to a speed normalization means that also receives the contents of the storage means opposite to that producing the raw roughness pulse.  The speed normalization means produces a speed normalized roughness signal having a magnitude varying inversely with the magnitude of just those contents of the opposite storage means counted up during the width of the raw roughness pulse.

Abstract: "SYNTHESIS OF 2-AMINO-2-DEOXYGLYCOSES AND  2-AMINO-2-DEOXYGLYCOSIDES FROM GLYCALS"                       ABSTRACT OF THE DISCLOSURE      O-acetylated glycals react with ceric ammonium nitrate in the presence of sodium azide to provide, in good yield, O-acetylated 2-azido-2-deoxy glycosyl nitrates.  These nitrates can be used to prepare 2-amino-2-deoxy sugars, such as D-galactosamine and lactosamine.  The O-acetylated 2-azido-2-deoxy glycosyl nitrates can alternately be con-verted to O-acetylated 2-azido-2-deoxy glycosyl halides which are useful in the preparation of O-acetylated 2-azido-2-deoxy glycosides, which in turn can be reduced to 2-amino-2-deoxy glycosides.  Of particular interest are the syntheses of 2-amino-2-deoxy glycosides which correspond to the terminal units of the antigenic determinant for the human A blood group. Attachment of these glycosides to a solid support provides immunoabsorbents which efficiently and preferentially absorb anti-A antibodies from blood plasma.
