Title: Method of recovering substances in the extraction of spent liquors from the delignification of lignocellulosic material by means of chloride-producing bleaching agents
Inventor: MANNBRO NILS V
IPC: D21C11/02
Filed: 1975-10-06
Granted: 1979-10-16
Abstract: Abstract of the Disclosure Lignocellulosic fibrous materials are delignified in two or more stages.  An introductory stage of digestion discharges brown stock and a black liquor which contains i.a. sulphur compounds wherein sulphur has an oxidation number that equals either -II (e.g. Na2S) or IV (e.g. Na2SO3).  Optionally, the brown stock is further delignified by means of oxygen, whereby oxystock and oxyliquor are obtained.  Stock from digestion, i.e. brown stock or oxystock, is subjected to delignifying oxidative bleaching using chlorine or chlorine compounds, the reac-tion products of which subsequently form chlorides in the bleaching effluent.     The non-chloride liquors, i.e. black liquor and oxyliquor, possibly also a low chloride fraction of bleaching effluents, are joined to form a lye which is recovered and combusted and includes the major part of the sulphur compounds used for digestion.  The lye combustion furnace releases compounds comprising sulphur of oxidation number -II and IV.     The chloride forming effluents, optionally including a minor lye fraction, are combined to form a brine which is subjected to another combustion which principally produces chlorides and compounds of sulphur of oxidation number IV (e.g. SO2) and VI (e.g. SO3 and Na2SO4).  This makes it possible to eliminate sulphur compounds, e.g. sulfidic compounds with oxidation number -II, from the brine recovery operations including separation of chloride, while the digestion chemical recovery sysstem only handles the lye.    By this means the digestion as well as the entire pulp mill system is relieved from chlorides, however, at least two combustion furnaces and two separate evaporation lines, one for lye and one for brine, are required.   The combined water evaporation from lye and brine can be kept on the same level as for a conventional single-line black liquor operation because brine substitutes wash water.

Abstract: ABSTRACT OF THE DISCLOSURE     A capacitor discharge ignition system employs charge and shut-off coils disposed about a common magnetic core. Shut-off may be a-chieved by selecting grounding an end of the trigger coil or the shut-off coil into the circuit which achieves the additional effect of loading the charge coil to protect the ignition capacitor. One circuit embodiment provides force commutation of the electronic switch, compensation for variations in temperature, inhibition of extraneous triggering of the electronic swithch and selective system shut-off. Extraneous triggering may be inhibited by the biasing of the electronic switch as a function of the polarity of the waveforms as well as by the damping of the transient which occurs at the end of the charge of the ignition capacitor. Gate protection for the electronic switch is provided by the clamping of the cathode to gate potential.

Abstract: MAGNETIC BRUSH DEVELOPER             Abstract of the Disclosure An auger fed magnetic brush developer wherein two parallel augers continuously recirculate the developer mix and cause the mix to be enriched with toner prior to its being returned to the magnetic brush roll.         A supply auger communicates with the brush roll along its entire length and directly elevates the mix to a lower part of the brush roll's surface.  This supply auger includes four flutes of a pitch equal to one-half the length of the brush roll.  This auger flute arrangement insures that a uniform supply of mix is presented to the brush roll along its entire length.  In addition, this supply auger construction insures that a uniform supply of enriched mix is presented to the brush roll along its entire length, since the gradually depleting carrier tends to be presented to the brush roll a minimum number of times, for example three, prior to its exiting one end of the supply auger.         The carrier exiting the supply auger enters a turnaround compartment whereat new toner is added.  The depleted carrier and new toner is mixed by a return auger.  To insure adequate triboelectric agitation, the  return auger includes two flutes of a pitch equal to that of the supply auger. The two augers are rotated at different flute and pitch related speeds which insure equal flow through the augers.         The two augers are of equal length, and are longer than the brush roll.  The two augers are mounted in axially offset fashion, with the opposite end of each auger substantially coextensive with opposite ends of the brush roll, and with the other end of each auger extending into end disposed turnaround compartments.                             -1a-

Abstract: ABSTRACT OF THE DISCLOSURE                A centrifugal pump having an impeller with a fingerlike projection on each blade extending radially outward from the impeller body into the outer annulus of the pumping chamber.  These projections cut through the liquid that has been centrifuged to the outer annulus causing a turbulence which draws a portion of the liquid into the body of the impeller for mixing with trapped air.  This mixing action causes the air to be centrifuged with the liquid and alleviates air locking in the pump and is especially valuable in a laundry washing machine where, in the last portion of the liquid extraction cycle, air and soap bubbles are likely to be included in the liquid.

Abstract: ABSTRACT OF THE DISCLOSURE Organotin derivatives of mercaptoalcohol esters corresponding to the general formula   wherein R and R' are hydrocarbon, m is 2 or 3 and q is 1 or 2 are prepared by reacting a mercaptoalcohol of the formula HS(CH2)mOH with a diorganotin oxide, organostannoic acid or an anhydride of said acid in an aqueous medium and subsequently esterifying the reaction product with the desired carboxylic acid, R'COOH, or an ester thereof.  The present method offers advantages over the prior art, which teaches reacting an esterified mercaptoalcohol with an organotin compound.  Compounds wherein R' is n-heptyl are unique in that they do not exhibit the disagreeable odors that characterize this class of compounds which are useful particularly as heat stabilizers for vinyl chloride polymers.
