Abstract: Oxidized weak  black  liquor  or  effluents from alkaline bleaching stages,  particularly oxygen delignification and/or ozone and/or hydrogen peroxide bleaching  effluents  are  treated  in process  stages which include an electrolytic cell to recover NaOH, lignin,    O2,   H2  and to achieve  other important benefits,   the most important of these are  (i)  to unload the evaporator-recovery furnace and lime-kiln causticizing plant,   and  (ii)  to enable a mill to implement  low-  or no-chlorine  bleaching techniques without  overloading  their  recovery  furnace  and/or lime kiln or requiring a new, larger recovery system, the electrolytic treatment can be carried out with one or a combination of the above types of effluents; it is also possible to increase the conductivity if required and thus the efficiency of the electrolytic cells and the yield/production of NaOH by the intro-duction of Na2SO4  (make-up or recycle from recovery furnace) and/or NaCl into the feed to the process; the  process  involves  pre-acidification  of  aqueous alkaline  liquid  containing  lignin   to   initiate precipitation of lignin, feeding the partly acidified liquid to the anolyte compartment of an electrolysis cell in which the anolyte and catholyte compartments are separated by a cation permselective membrane, and in which the catholyte compartment is provided with a source  of  hydroxide    cations  by    carrying  out electrolysis to effect migration of sodium ions into the  catholyte  compartment,   and  simultaneously  to acidify  the  liquid  in  the  anolyte  compartment  to substantially complete lignin precipitation;   sodium hydroxide is recovered from the catholyte compartment and lignin is recovered from the anolyte compartment.

Title: Chill roll

Granted: 1992-12-01
Abstract: CHILL ROLL                ABSTRACT OF THE DISCLOSURE      A chill roll for cooling a web,  such as in the printing industry, where a uniform temperature across the chill roll  is maintained.   Journals support an outer roll assembly and an inner roll assembly.   The inner roll assembly is bearing mounted on the inner ends of opposing journals and the outer roll is rotated about the inner roll, which is weighted to free-wheel about the bearings to minimize rotary motion.  Coolant is introduced through the journal on one end and into a center tube, where the coolant uniformly flows in an annular space between the rolls and along the length of the    inner    and    outer    roll    assemblies    to circumferentially  traverse  between  the  rotating  and stationary outer and inner rolls.   This coolant flow provides enhanced heat transfer from the outer rotating chill roll to the circulating coolant.  Heated coolant collects  and  returns  through  a  center  tube,  and exhausts through the center tube and out through the journal.  Turbulence inducer bars between the inner and outer  roll  assemblies  creates  a  turbulence  in  the coolant  glow between the  outer and  inner rolls  to further enhance heat transfer.

Abstract: WRITE BACK BUFFER WITH ERROR CORRECTING CAPABILITIES                           ABSTRACT      In the operation of high-speed computers, it is frequently advantageous to employ a high speed cache memory within each CPU of a multiple CPU computer system. A standard, slower memory configuration remains in use for the large, common main memory, but those portions of main memory which are expected to be used heavily are copied into the cache memory.  Thus, on many memory references, the faster cache memory is exploited, while only infrequent references to the slower main memory are necessary.  This configuration generally speeds the overall operation of the computer system; however, memory integrity problems arise by maintaining two separate copies of selected portions of main memory.  Accordingly, the memory access unit of the CPU uses error correction code (ECC) hardware to ensure the integrity of the data delivered between the cache and main memory.  To prevent the ECC hardware from slowing the overall operation of the CPU, the error correction is performed underneath a write back operation.  Data contained in the cache, which will be displaced by data received from main memory 10, is transferred to a write back buffer (WBB) during that period of time between the request for data from the main memory and actual delivery of the requested data. Further, the ECC hardware also operates on the cache data being written to the WBB.  Accordingly, a performance penalty is avoided by performing error correction and preremoving the cache data during that idle period of time.

Abstract: A graft copolymer is made by grafting, by a free radical  reaction mechanism in  aqueous  solution,  water soluble ethylenically unsaturated monomeric material on to a water soluble substrate having hydroxyl groups, and the free radicals are formed on the substrate using an oxidising metal capable of being reduced by the substrate to  a  lower  valency  state  (for  instance  cerium)  and persulphate or other peroxy compound capable of oxidising the metal back to a higher valency state.   The process is preferably conducted as a reverse phase polymerisation process and the invention includes also a novel reverse phase emulsion comprising a dispersion of reverse phase polymer particles of a graft copolymer of carboxymethyl cellulose, dextran or starch with acrylamide and acrylic acid and/or AMPS.

Abstract: ABSTRACT OF THE DISCLOSURE     A method for selectively treating permeable strata in a subterranean formation which is penetrated by a well.  In particular, a first fluid is injected into the well to a location which is adjacent to a first permeable stratum at a rate which is greater than the flow rate for the first fluid into the first permeable stratum.  Simultaneously, a second fluid is injected into the well to a location which is adjacent to a second permeable stratum at a rate which is less than the flow rate for the second fluid into the second permeable stratum.  The second fluid is adapted to treat the second permeable stratum.  This method provides an economical technique for selectively treating the first permeable stratum while treatment of the first permeable stratum is avoided.

The blank can be made of cardboard with a coating of aluminum film or foil, for lining the interior of the container and the bend line is interrupted by at least one geometrical surface portion which projects into both portions of the blank, which are adjacent to the bend line, that is to say, the edge strip portion and the wall portion, and the stabilizing member is separated from the edge strip portion and the wall by bend lines which are at least partly cut. In both cases, at least the bend line is preferably produced by stamping or embossing, or by perforations.

Abstract: A tapping attachment (1) for threading a relatively large number of holes through a sheet metal part at a relatively low cost per hole. The tapping attachment includes a thrust bearing assembly (6) which is aligned with a turret-type punch press or the like and movable in response to an axially directed force generated by the punch press. The axially directed force applied from the press to the thrust bearing assembly is transferred to a spline shaft (26). The spline shaft is rotated within and moved linearly relative to a screw threaded roller nut (74), whereby the axially directed force is converted into a rotating force for advancing and turning a tap (80) at high speeds of rotation. A nitrogen reservoir (14) is provided so that a supply of gas is available for returning the thrust bearing assembly and the spline shaft to their initial positions in order that a new hole can be tapped in response to another axially directed force. Also provided is an oil reservoir (12) so that a supply of oil is available for lubricating and cooling the tap via an oil spout.
