Abstract: ABSTRACT    For providing reciprocal motion to an element in a direction normal to a given reference line, and including the feature of uniformly reducing the reciprocal motion to zero, a transmitting link, connected to the element, is constrained for movement in an arcuate slot formed in an oscillating member.  Displacement means moves the link to an initial position along the arcuate slot such that the link is subjected to a reciprocal motion of given amplitude.          As returning means moves the link back along the arcuate slot, the reciprocal motion reduces to zero.  The point at which motion becomes zero is the point of coincidence between the pivot point of the oscillating member and the termination of the arcuate slot.

Abstract: ABSTRACT       Compatibility of solvent refined coal and other coal liquids with conventional petroleum fuels is improved by moderate catalytic hydrogenation of the solvent refined coal liquid to a hydrogen to carbon atomic ratio less than that of corresponding petroleum fractions.  As degree of hydrogenation of solvent refined coal is increased, compatibility with petroleum fractions of like boiling range increases to a maximum measured by precipitation of sediment from the blend of equal parts of the two fuels.  That maximum is achieved at a hydrogen/carbon ratio below that of the corresponding petroleum fractions.  As that ratio is increased toward the ratio characteristic of a like petroleum fraction, compatibility is impaired.

Abstract: Abstract of the Disclosure In a speech recognition system for programming or commanding computers and other machines, there is described a recognition system which is less susceptible to breathing and other background noises.  Speech-like signal durations are detected from input signal waves from all sources.  The waveforms of the input signals are analyzed and recognition parameters are extracted.  A spectral change detecting unit detects the magnitude of short-time spectral changes from the speech-like signal durations, determining thereby whether the speech-like signal is speech.  A recognition unit re-cognizes speech patterns from signals within the speech-like signal durations and rejects those signals which the spectral-change detecting unit indicates do not contain speech.  The parameter extracting means and the spectral change detecting unit receive controlling signals from a control unit.

Abstract: ABSTRACT OF THE DISCLOSURE   .         Several embodiments are disclosed of a bottom stop of a slide fastener of the type comprised of three members, two secured to one stringer tape and one to the other, such that   once the three members are passed through the Y-shaped channel, they interengage to form a unitary stop member that cannot be disassembled.  Contrary to prior art wherein at least one part of the stop member is of a greater maximum width than the maximum width of the respective channel of the slider, to secure abuttive opposition to the movement of the slider, the invention provides elements that can all pass relatively smoothly through the respective slider channels when assembling the stop.  The abutting action is achieved by a concave protrusion on one of the members  by its engagement with the neck of the slider.  The interengagement of the  members is such as to prevent separation of the assembled stop both transversely of and perpendicularly to the fastener rows, while facilitating the assembling by avoiding forced passage of at least one stop member  through the slider and the resulting damage to at least one of the members   to the channel of the slider or to both, frequently encountered in prior art stops of this type.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides a process for the selective production of individual pure halides and/or mixtures of halides from a mixture of solid oxides, either without or with only one single reducing halogenation stage using the known series of halide-forming affinities, characterised by the following features:  (a) the comminuted mixture of solid oxides is loaded into the front end of a unit having as many zones as the number of halides or halide mixtures to be produced, and is passed through it; (b) into the rear end of the unit is fed a halide of an element with a lower halide-forming affinity than that of the lowest halide-forming affinity of those to be produced.  The quantity of halide supplied is equivalent to the total halogen content of the halides to be extracted from the units; -(c) the halide fed into the rear end of the unit and the solid oxide or mixture of oxides arriving there are converted by oxygen-halogen exchange to a solid oxide and a gaseous halide or mixture of halides; (d) the solid oxide formed in the rear end of the unit is separated from the halide or mixture of halides and is removed from the unit; (e) the gaseous halide or mixture of halides formed in the rear end of the unit is brought in contact in counter-current flow with the solid oxide mixture further to the front of the unit whereby again through an oxygen-halogen exchange - an individual gaseous halide or mixture of halides is formed in each zone of the unit; (f) fractions of the gaseous halides or mixtures of halides formed in the individual zones are separated from the solid oxides and extracted from the unit in quantities such that the extracted amount of halide of each element is equivalent to the amount of oxide mixture loaded into the front end of the unit.

Title: Exhaust gas sensor electrical circuit improvement
Inventor: HEINEY ELMER T III
IPC: G01N27/12
Filed: 1980-01-03
Granted: 1981-11-17
Abstract: ABSTRACT An exhaust gas sensor electrical circuit is im-proved by the provision of circuit means for inhibiting reduction in the magnitude of the change in voltage signal produced in the sensor circuitry.  The reduction in magni-tude change would otherwise result from prolonged exposure of the sensor ceramic elements to exhaust gases produced by combustion of a rich air/fuel mixture or a lean air/fuel mixture.  The sensor has a titania or other exhaust gas sensing element responsive to temperature and to the partial pressure of oxygen.  A second metal oxide ceramic element also is responsive to exhaust gas sensor temperature, but is more slowly responsive to the partial pressure of oxygen in the exhaust gases.  Prolonged exposure of the second element in the sensor to rich-mixture exhaust gases or to lean-mixture exhaust gases can lead to a temporary but substantial loss of output signal magnitude from the sensor in the absence of the inhibiting means of the improved circuitry.
