Abstract: ABSTRACT OF THE DISCLOSURE             Novel immunoassays are provided employing discrete particulate reagents for determining an analyte which is a member of a specific binding pair-ligand and homologous receptor.  The assay employs as a first reagent, a member of said pair bound to an insoluble particle (particle conjugate); as a second reagent, a label which is part of a signal producing system, bound to a member of said pair (signal label conjugate); and as a third re-agent, a signal repressor comprising an inso-luble particle, where the signal repressor is obstructed from interacting with said label of said signal label conjugate, when said signal label conjugate is bound to said particle conjugate.           In performing the assay, the analyte, the reagents, and any ancillary materials are combined in an aqueous assay medium and the signal determined as compared to an assay medium having a known amount of analyte.       The repressor greatly enhances the sensitivity and accuracy of the immunoassay in repressing the signal produced by labels which are not bound to the particle conjugate, thus substantially limiting the observed signal to label bound to the particle conjugate.  The labels which are employed provide a signal which does not differ significantly from when the signal label conjugate is bound to the particle conjugate or is free in the bulk solution. Illustrative labels include chromogens, such as fluorescers, chemiluminescers, and the like.      Particular reagents and kits are provided, where the kits have predetermined amounts of the various reagents to substantially optimize the sensitivity of the assay.

Abstract: ABSTRACT OF THE DISCLOSURE        A sealing slide fastener stringer includes a stringer tape made of synthetic rubber and a series of coupling elements of synthetic resin injection-molded on a longitudinal edge portion of the stringer tape.  The stringer tape has a thickened sealing member along the longitudinal edge portion. Each coupling element includes a pair of members one on each side of the tape, each comprised of a leg on the edge portion, a neck on the sealing member, and a coupling head projecting beyond the sealing member.  The legs are inter-connected by a first connector extending through the edge portion, and the necks are interconnected by a second connector extending through the sealing member.  The first and second connectors may either be integral or comprise rivets.  A single integral connector may alternatively be used to connect the legs and necks of the coupling element members.  The advance in the art is in that the fastener is capable of withstanding severe thrust applied perpendicuarly to the plane of the fastener thus avoiding the tendency to become displaced out of sealing contact.

Abstract: ABSTRACT OF THE DISCLOSURE       Aluminous ore such  as bauxite containing alumina is blended with coke or other suitable form of carbon and reacted with sulfur gas at an elevated temperature.  For handling, the ore and coke can be extruded into conveniently sized pellets.  The reaction with sulfur gas produces molten aluminum sulfide which is separated from residual solid reactants and impurities. The aluminum sulfide is further increased in temperature to cause its decomposition or sublimation, yielding aluminum sub-sulfide liquid (AlS) and sulfur gas that is recycled.  The aluminum monosulfide is then cooled to below its disproportion-ation temperature to again form molten aluminum sulfide and aluminum metal.  A liquid-liquid or liquid-solid separation, depending on the separation temperature, provides product aluminum and aluminum sulfide for recycle to the disproportion-ation step.

Abstract: PHOTOELECTRIC DEVICE AND METHOD OF PRODUCING THE SAME      Abstract of the Disclosure A photoelectric device has an impurity region disposed in a semiconductor substrate, and a photoelectric conversion portion which is constructed by stacking an electrode layer lying in contact with at least a part of the impurity region.  A photoconductive layer overlies the electrode layer, and a transparent electrode overlies the photoconductive layer.  The invention is characterized in that the photoconductive layer is made of an amorphous chalcogenide material which principally  contains Se.  Preferably, the amorphous material principally containing Se is partially doped with Te to enhance its sensitivity.  The amorphous chalcogenide material is very useful in the following respect.          During forming, or after having been formed, the photoconductive layer has an uneven surface.  This surface is flattened by heat treatment at a temperature of at least the softening point of the material of the layer.  In this way discontinuous parts of the photoconductor ascribable to the uneven surface can be avoided.

Abstract: A B S T R A C T   The process relates to hydroxylammonium salts. The cyclic process for the preparation and processing of a hydroxylammonium salt solution, in which an aqueous acid reaction medium is kept in circulation between a hydroxylammo-nium salt synthesis zone and an oxime synthesis zone, and in which the circulating liquid is continuously supplied with ni-trogen monoxide, which serves a nitrogen source for the forma-tion of the hydroxylammonium salt, and which is converted into hydroxylamine by catalytic reduction with hydrogen.       The circulating liquid is, before it enters the hydro-xylammonium salt synthesis zone, subjected to a stripping pro-cess by bringing the circulating liquid via a heat-exchanging surface in heat-exchange with nitrogen monoxide containing water vapour, upon which the water vapour condenses, and the remaining gas containing nitrogen monoxide to hydroxylamine.

Abstract: PHN. 9652 ABSTRACT:           A multiprocessor computer system is distributed over error-isolation areas, each of these areas containing a processor element, an encoder, a section of a memory and an information-reconstruction section which are connected in this order in a cyclic path.  The processor elements work in parallel on the same data-word, which has a certain length.  When the result of the processing has to be stored in the memory, each encoder forms a code-symbol of shorter length, on the basis of the data-word.  The set of code-symbols formed on the basis of the data-word forms a code-word with a larger bit length than the data-word mentioned. By means of an error-correcting code at least one erroneous code-symbol in the code-word can be corrected.  The code symbols are stored in the respective memory sections.  If the data-word concerned has to be further processed, all corresponding code-symbols are fed to all information-reconstruction sections.  Peripheral equipment can be connected in the cyclic path, with implementation of dis-tinctive levels of redundancy.

Thus, high frequency detail is not lost.  This is determined by looking at proximate samples to see if their amplitudes are within a selected amount of each other.  The averaging typically is of two or four picture samples depending upon how great an area has only low frequencies, but greater numbers of samples can be used.

Abstract: ABSTRACT OF THE DISCLOSURE        The motor braking system for use with an alter-nating current motor and an AC power source includes a power circuit for supplying a DC braking current to the motor.  A capacitor which was charged during motor opera-tion, discharges when the motor is turned off and thus provides a pulse of energizing current to a contactor which quickly connects the power circuit to the motor and starts the electric braking cycle as soon as the AC source is disconnected from the motor.  A timing circuit is also started and maintains the   energizing current for a predetermined amount of time while the motor is coming to a stop.  A mechanical brake may also be used to complete the stopping sequence if desired, with the mechanical brake being engaged when the braking current is terminated.
