Abstract: ABSTRACT        A method of treating an aqueous alkaline alkali metal sulfide-containing liquor to remove the sulfur values therefrom.  Broadly, the method comprises introducing an alkaline liquor containing at least about 60 mole % of an alkali metal sulfide into a neutralization zone.  In the neutralization zone, it is intimately contacted and reacted with a sufficient amount of a gas containing a major amount of H2S to produce a product liquor of reduced alkalinity comprising a major amount of an alkali metal bisulfide and a minor amount of an alkali metal carbonate and bicarbonate.  The product liquor is withdrawn from a neutralization zone and introduced into a carbonation zone. In the carbonation zone, the liquor is contacted with a sufficient amount of a dilute CO2-containing gas to produce a product stream comprising alkali metal carbonate and bicarbonate crystals substantially free of alkali metal sulfide and sulfite and an H2S-rich product gas.  The H2S-rich product gas so produced is recovered, and about 35 to 65% of it is introduced into the neutralization zone. Advantageously, the remainder of the H2S-rich product gas is passed to a conventional Claus plant for recovery of the sulfur values therefrom.  The product stream of alkali metal carbonate and bicarbonate is thermally decomposed to produce a CO2-rich offgas and an aqueous slurry containing a major amount of alkali metal carbonate and a minor amount of alkali metal bicarbonate.  At least a part, and preferably all, of the CO2-rich offgas from the thermal decomposition is recovered for introduction into the carbonation zone.  Additional CO2 is provided in the carbonation zone by the introduction therein of a waste gas containing less than about 35% CO2 by volume.

Abstract: INVENTOR:   WALTER EICHER          INVENTION:  SWITCHING METHOD FOR MEASURING TWO NEIGHBORING             FLYING TARGETS OR OBJECTS IN SUCCESSION              ABSTRACT OF THE DISCLOSURE           A switching method for measuring or tracking two neighboring flying targets in succession by means of a measuring installation having a television system. A re-gulation system receives course signals, which corre-spond to the deviation of the image of a flying target or object from the image center, and aligns the line of sight of the television camera at the flying target. An electronic window limits the formation of the deviation signals to the contribution of the image point of the flying target located in the window.  During measurement of the first flying target by means of first deviation signals and a first window there is produced about the image center a second window and second deviation signals which are delimited by the second window.  The first deviation signals are added, by actuating a control handle or stick to additional signals, in order to shift the line of sight and thus bring the image of the second flying target into the image center.  Thereafter the re-gulation system is switched into operative relationship with a control by the second deviation signals.           The invention is used to eliminate the effects of alignment errors and transient phenomena upon switching the measurement from one flying target to another flying target.

Abstract: METHOD AND APPARATUS FOR DISPLAYING A VIDEO PICTURE       ON A MATRIX OF LIGHT EMITTING ELEMENTS                  ABSTRACT OF THE DISCLOSURE           A method and apparatus for displaying a video picture on a matrix array of light emitting elements formed of m rows and n columns of such elements.  The video signal, which is comprised of periodic vertical intervals, each containing suc-cessive line intervals of video information, is sampled at a rate of n samples during each line interval.  The resultant, n sampled picture elements for each sampled line interval in each vertical interval are stored.  During a vertical interval, a given light emitting element, such as the i-th element in the j-th row, corresponding to a sampled picture element in a respec-tive line interval, is energized for a duration greater than a line interval and less than a vertical interval as a function of the brightness of the sampled picture element when that sampled picture element is between and black and peak white levels.  In a practical embodiment, a storage circuit stores the n sampled picture elements in each line in an m x n matrix array of storage elements.  These stored, sampled picture ele-ments are recirculated on a row-by-row basis periodically, all of the sampled picture elements being fully recirculated in a period which is less than the vertical interval.  Each of the m rows of light emitting elements are conditioned sequentially and repetitively, in synchronism with the recirculation of the sampled picture elements in the storage circuit.  A reference voltage generator generates a reference voltage of staircase waveform during each vertical interval, the step interval of the staircase waveform being equal to the aforementioned period.              -i-During each such period, the brightness of each picture element which is shifted into the first row of the storage circuit is compared to the reference voltage, and the columns of light emitting elements are selectively enabled for a duration that is a function of the brightness level of corresponding sampled picture elements.  A light emitting element is energized if it is disposed in a row which is conditioned and in a column which is enabled.                             -ii-

Abstract: ABSTRACT OF THE DISCLOSURE         A gritless seal, a method for making the seal, and a method for forming a joint with the seal between over-lapped ligature segments is provided.  In the preferred embodiment, the seal has a body which includes a generally rectangular-shaped central portion and a pair of generally rectangular-shaped legs each connected to the central portion by a longitudinally extending bend.  The seal has an  inner gripping layer for lying in surface contact with the over-lapping ligature segments and has an outer, ductile layer of material adjacent the inner layer.  The inner gripping layer is brittle and has a hardness greater than that of the outer, ductile layer. In forming the joint, the seal is disposed about the overlapped ligature segments and is folded, squeezed, and/or crimped about the segments under pressure sufficient to deform the outer, ductile layer and produce fracture cracks in the inner gripping layer which present sharp edges to engage and hold the surfaces of the overlapping ligature segments and whereby the inner grip-ping layer is maintained against the surfaces of the over-lapping ligature segments by the deformed, outer, ductile layer.  The seal is made from sheet steel stock by coating the outer surface with a non-ferrous masking material and then submerging the seal in a bath or sodium cyanide, sodium chloride, and graphite at 1500°F for 15 minutes after which the seal is quenched in oil.
