Abstract: ABSTRACT OF THE DISCLOSURE    A dot matrix print head control circuit is capable of selectively requesting and receiving a predetermined set of print head control head control data from a digital data processor which successively transmits plural sets of such digital data and corresponding data acknowledge pulses in response to a data request signal. The micro-processor is thus enabled to independently control two print wire arrays in a dot matrix print head using identical circuits which are thus more economically formed as LSI chips. Each such identical print head control circuit has a "role determining" circuit which can be initialized such that its associated print head control circuit, although identically constructed, is capable of selecting a predetermined set (e.g. byte) of digital data from among the plural sets (e.g. bytes) of digital data transmitted in succession by the microprocessor. The identical print head control circuits are capable of effecting different print functions in response to the selectively received data set.

Abstract: ABSTRACT OF THE DISCLOSURE        A method of making a reaction bonded/hot pressed silicon nitride comprising object is disclosed.  To form a protective amorphous glass on crystallites in the final product, an Al2O3/SiO2 ratio must be maintained which is greater than 2.  Second phase crystallites are formed prior to hot pressing.  a mixture of silicon, SiO2, and .4-2.3 molar percent (by weight of the silicon) of oxygen carrying agents, i.e., Y2O3 and Al2O3, is preformed and reaction nitrided to form discs or billets having at least 60% alpha Si3N4 and a high proportion of second phase crystallites which displace substantially all silicate glass except for a controlled small quantity (.2-1% by weight).  The reactive amounts of Y2O3, Al2O3 and SiO2 are controlled to assure formation of substantially YlSi12O24N4 as the second phase crystallite.  Al2O3 is controlled in an amount of .4-4% by weight to insure that the small proportion of glass has little or no microporosity associated therewith and serves to protect the oxynitrides against linear oxidation kinetics.

Abstract: Abstract:   A carrier lifetime measuring apparatus has a first photon beam of a wavelength capable of rendering the optical absorption coefficient of a semiconductor sample small when the semiconductor sample having a potential barrier in the vicinity of its surface is irradiated with the radiation.  Both such first photon beam and a second photon beam of a wavelength capable of rendering the optical absorption coefficient large, are respectively chopped and then employed to irradiate alternately an identical position on the semiconductor sample.  First and second photovoltages are generated in the semiconductor sample by these photon beams,  Such voltages are detected by capacitance coupling and the ratio between a first amplitude variation and a second amplitude variation is obtained from the amplitudes of these detected photo-voltages.  These measurements enable evaluation of a minority carrier lifetime in the sample.

Abstract: IMPROVED FIBER OPTIC ROTATION SENSOR     WITH EXTENDED DYNAMIC RANGE           Abstract A fiber optic rotation sensor,  employing the Sagnac effect comprising all  fiber optic components positioned along a continuous, uninterrupted strand of fiber optic material.  The rotation sensor includes a detection system utilizing a modulator or modulators for phase modulating at first and second harmonic frequencies light waves which counter-propagate through a loop formed in the fiber optic strand.    Each  modulator  is  operated  at  a  specific frequency  to  eliminate  amplitude  modulation  in  the detected optical output signal.    A phase sensitive detector generates a feedback error signal proportional to the magnitude of the first harmonic in the output optical signal.   The feedback error signal controls a modulator which controls the amplitude of the second harmonic driving  signal  for the second harmonic phase modulator such that the first harmonic component in the output signal from the rotation sensor is canceled or held within a small range of amplitudes.

Abstract: ABSTRACT   A method of separating lighter and heavier particles in a solids mixture includes entraining the mixture in a liquid of a specific gravity intermediate the specific gravities of the lighter and heavier particles.  The liquid with entrained mixture is fed through a first opening into one end of a vessel and revolved therein by rotating the vessel.  The vessel is designed so that the liquid attains a dynamic equilibrium at which an annular, centrifugally induced, substantially static, revolving volume of the liquid of stable internal surface is confined by the vessel about the axis of revolution while further liquid flows on within the stable internal surface.  The heavier particles are thereby centrifugally directed into the annular volume while the lighter particles remain entrained in on-flowing liquid which flows out a second opening in the other end of the vessel.  Feeding of the mixture to the vessel is discontinued, and the rotating vessel slowed and stopped to release the annular volume of the liquid, which then, with the heavier particles entrained, swirls towards and flows through one of the openings.    In apparatus for performing this method, bearing means is provided to support the vessel for rotation about the axis of revolution, which passes through or near the openings, and the vessel has a smooth continuous interior surface, free of negative slopes, edges or bends for a liquid droplet swirling towards the one opening, whereby sufficient swirling liquid is able to clean the whole of such smooth interior surface of heavier particles.

Abstract: LOW-SODIUM SALT SUBSTITUTE            ABSTRACT    A low-sodium seasoning composition adapted as a substitute for common table salt and as a magnesium dietary supplement comprised of from about 40 to about 50 weight percent of sodium chloride in admixture with from about 25 to about 35 weight percent of potassium chloride and from about 15 to about 25 weight percent of magnesium salt, including magnesium sulfate or magnesium chloride.  The particular low-sodium salt substi-tute formulation results in a synergistic or enhanced saltiness taste per unit weight through the combination of the sodium and potassium salts without any potassium-generated bitterness or bitter after-taste sensation because of the presence of magne-sium salt which masks or overcomes such bitterness or after-taste while providing desirable magnesium dietary supplementa-tion.  Thus, it has been found that only about 70 to 90% of the unit weight of table salt required to obtain a level of salti-ness taste is required for the low-sodium salt substitute composition to obtain the same level of saltiness taste.  Use of the proposed low-sodium salt substitute results in a reduc-tion of sodium intake of greater than 50% with respect to table salt in the attainment of an equivalent level of saltiness taste.

Abstract: ABSTRACT OF THE DISCLOSURE          The multipole acoustic wave logging device of this invention includes a logging sonde, means for generating a 2n-pole acoustic wave in a virgin earth formation surround-ing a borehole but separated from the borehole by an invaded zone, where n is an integer greater than zero, and means for detecting the refracted arrival of the 2 -pole acoustic wave.  In the preferred embodiment the generating means com-prises four similar sectors of a hollow piezoelectric cylin-der.  The four sectors are polarized radially and are so con-nected to the sonde that they are in the form of a split cylinder coaxial with the sonde axis.  Electrical pulses are applied across the inner and outer cylindrical surfaces of each sector.  The electrical pulses are of such polarities that adjacent sectors vibrate radially in substantially oppo-site phase.  The vibrations of the sectors will generate com-pressional waves in the borehole liquid which will interfere to produce a quadrupole acoustic wave in the surrounding earth formation.  The acoustic wave will be refracted in the virgin formation and detected by the detecting means.  The detecting means comprises two detectors in the borehole spaced apart longitudinally from each other and from the gen-erating means.  If the 2n-pole acoustic wave is a compres-sional wave, the compressional wave velocity of the virgin formation is determined from the time interval between detec-tions of the refracted arrival of the 2n-pole acoustic wave by the two detectors.  If the 2n-pole acoustic wave is a shear wave, the shear wave velocity of the virgin formation may similarly be determined.  The radius of the invaded zone may be determined from the compressional wave velocity in the virgin formation and in the invaded zone or from the shear wave velocity in the virgin formation and in the invaded zone.
