Abstract: REHYDRATOR                       Abstract The rehydrator is comprised of a first plate having a plurality of hollow tubes secured in through apertures and extending from one side of the plate perpendicular thereto.  A plurality of rods are secured to a second plate disposed parallel to the first plate and extend through respective tubes in the first plate.  The second plate is guided for movement toward and away from the first plate on a plurality of guide rods and springs are provided to normally bias the second plate away from the first plate.  The rods slide loosely within the tubes and upon movement of the second plate downwardly into engagement with the first plate, the ends of the rods will extend beyond the tubes so that upon immersion of the ends of the rods and tubes into a solution, the withdrawal of the rods into the tubes will cause a predetermined amount of fluid to be drawn into the tube. Subsequent extension of the rods past the ends of the tubes will cause the liquid therein to be dispensed into appropriate receptacles aligned with each tube.

Granted: 1983-07-12
Abstract: Disclosed in a wet process for producing a CuS cathode having a high capacity and reduced tendency to induce swelling when incorporated into a cell having a non-aqueous electrolyte and a lithium anode. Elemental copper and sulfur are dispersed in an aqueous HCl solution free of ionic contaminants. After reaction, the resulting cupric sulfide is washed with an aqueous solution of a mixture of, e.g., ammonium chloride and hyrochloric acid, to remove cuprous ions. The product is then washed with water until the chloride ion content of the wash water is less than about 5 ppm. The washed solid product is then dried to subline residual NH4Cl, pressed to form a shape retaining cathode, subjected to a final heat treatment and incorporated into a cell or battery having a lithium metal anode and a nonaqueous electrolyte.

Abstract: MORTARLESS CONCRETE BLOCK SYSTEM HAVING REINFORCING BOND BEAM COURSES Abstract of the Disclosure In a mortarless interlocking concrete block system, general purpose intersection blocks 40 have parallel grooves 47 formed on their bottom surfaces 46, but each has mating ridges 45 on the upper surface 44 o  its inner end 41 only.  The top surface 44 of its corner end portion 51 is flat, to permit an overlying course to fit thereon either at right angles or in linear alignment.  The corner end portion 51 has, in each of its two opposite side faces 54, 56 and in its outer end face 52, parallel vertical grooves 53, 55, 57 matable with tongues 17 on the system's stretcher blocks 10, to pro-vide interengagement at both left and right corners and T-shaped and crossing-wall intersections.  For bond beam courses, a bond beam intersection block 90 with similarly grooved 112, 114, 116 corner end 110 faces 111, 113, 115 has at its inner end portion 93 a closed-bottom channel 99 with saddle-like webs 101 extending between the chan-nel sides 92, to open through to its corner core 120 and support horizontal reinforcing rods b.  Consistently formed bond beam blocks 70 are provided, whose tongues 75 may engage any of the grooved 112, 114, 116 corner end 110 faces 111, 113/ 115 at wall corners and intersections. Breakout provisions 121 in the corner core 120 inward of these faces 111, 113, 115 make it simple, at any inter-section, to lead horizontal reinforcing rods b to the cored corner 120 end portions 110, through which vertical rodding a and grouting is provided.  By utilizing hori-zontal reinforcing rods 133 formed at a right angle to extend through the corner block 90 between its two adja-cent blocks 70, the two perpendicular walls may be more securely tied together, to prevent vertical cracking. This furnishes to the easily-constructed mortarless wall block system a sturdy, reinforced concrete grid.          Where desired, blocks made of other material, for example, redwood may be utilized; also in miniature, the invention may be incorporated in sets of toy blocks, which have exceptional educational value.

Abstract: UPFLOW REACTOR FILTER ASSEMBLY            ABSTRACT OF THE DISCLOSURE         The upflow filter assembly includes a primary chamber situated above a secondary chamber within an en-closure and having a filter element spanning the primary chamber towards the upper end thereof.  Airlocks are si-tuated near the dividing floor of the two chambers so that when in the liquid treating or filtering mode, they operate to maintain the air/liquid interface between the chambers and prevent liquid from passing into the secondary cham-ber assisted by compressed air introduced into the second-ary chamber.  Liquid containing solids and/or flocculents, is fed into the primary chamber adjacent the lower side thereof and gradually fills the chamber with much of the flocculents and solids settling out by gravity.  The par-tially deflocculated liquid then passes up through the fil-ter element to a height above the filter element with ex-cess, relatively clear effluent flowing out through an out-let spaced above the filter element to provide a hydraulic head above the filter element.  As the liquid passes upward-ly, it passes through the flocculent mat formed in the pri-mary chamber which also acts as a filter.  When it is de-sired to flush the filter assembly, the secondary chamber is opened to the atmosphere through a conduit extending up-wardly through the filter assembly, and the compressed air is closed off.  This releases the airlocks and the liquid and sludge from the primary chamber flushes through the airlocks into the secondary chamber and thence through an outlet to be discharged.  The hydraulic head of liquid above the filter element flushes downwardly through the filter element and assists in cleansing same.

Abstract: ABSTRACT OF THE DISCLOSURE          The hydroxyl group content of preforms manufactured by the MCVD process for use in manufacturing optical fibres is reduced by conducting isotopic exchange between hydrogen and deuterium near the internal walls of the silica glass supporting tube. The operation is carried out in two steps, first by inducing deuterium adsorption and then by thermally activating the ex-change reaction.  The fibres obtained from the preforms have improved light-transmitting properties as they are not subject to attenuation due to absorption corresponding to the second and third overtones of the vibration of the -OH bond.

Abstract: PROCESS FOR DESULFURIZATION, DEDUSTING AND DISCHARGE OF HOT FLY ASH-CONTAINING FLUE GAS AND BAGHOUSE UNIT FOR USE IN THE PROCESS.         ABSTRACT In connection with the desulfurization and dedusting of flue gas where use is made of a combined spray drying and absorption and the material produced by this process is filtered off from the gas stream together with fly ash, a heating of the flue gas is performed prior to its discharge into the atmosphere by admixture of hot, non-purified flue gas. This admixture takes place so that the flue gas serving for the reheating passes through only a part of the available filter area, which allows the remaining part of the filter area to be kept at a relatively low temperature.          This results in a particularly high sulfur dioxide ab-sorption being achieved during the passage of the flue gas through the filter.          A baghouse unit divided up in a special manner can be used in the process.
