Abstract: ABSTRACT OF THE DISCLOSURE       The phenolic chelate resin has a chelate-forming group wherein part or all of the hydrogen atoms in a primary and/or secondary alkylamino group introduced in a phenol nucleus are replaced by a methylenephosphonate group.  Also disclosed is a process for producing such a chelate resin, and a method for recovering heavy metal ions with such a resin.  The resin has particularly high selectivity for adsorbing uranium  ions, as well as high heat, acid and alkali resistance as well as dimensional stability  The resin is very effective for recovering uranium from various uranium containing solutions such as sea water, crude phosphoric acid fertilizer solutions; low-grade uranium ore, waste water from uranium refining, and uranium mine water.

Abstract: ?-22970 METAL SUBSTRATE FOR AN ELECTROCHEMICAL CELL        ABSTRACT OF THE DISCLOSURE    A metal current collector substrate adapted to be inserted into an elongated cylindrical housing of a primary electrochemical cell.  The metal current col-lector substrate is employed together with porous carbon and fiberglass separator elements to form a carbon current collector electrode/separator assembly for use in the electrochemical cell.     The metal current collector substrate in accor-dance with the invention comprises a thin, circular, metal disc (e.g., of nickel) having a plurality of curved notches around its periphery.  The notches are equally-spaced about the periphery of the disc (e.g., at 45° intervals) and define a plurality of deflective, resilient arcuate portions intermediate to the notches. Prior to insertion into the housing of the cell, the disc is flat and has a diameter greater than the inter-nal diameter of the housing.  The disc is inserted into the housing by pushing the disc longitudinally into the housing whereupon the arcuate portions are deflected upwardly by physical contact with the inter-ior wall of the housing.  This deflection causes the arcuate portions to move toward each other and in turn to cause the disc to generally conform to the interior cross section of the housing.  The arcuate portions following the deflection thereof are at acute angles with respect to the interior wall of the housing and make direct physical contact with the wall of the housing.  In addition, due to the adjacency of the notches in the disc to the wall of the housing a plurality of passageways are established between the disc and the interior wall of the housing.

Abstract: ABSTRACT            Separation of Cobalt and Nickel The invention relates to the preferential precipitation of cobalt from aqueous acidic sulphate solutions of nickel and cobalt.      The separation is carried out by introducing at least a stoichiometric amount of Caro's Acid containing no more than a small amount of hydrogen peroxide into the nickel/cobalt solution progressively over a period of at least an hour, whilst maintaining the solution at a pH from 3.1 or 3.5 up to 4.7 by addition of an alkali metal hydroxide carbonate or bicarbonate, or at 4.3 to 4.7 with the corresponding ammonium compound, and, thereafter separating the precipitate from the aqueous cobalt depleted solution.      In preferred features, the Caro's Acid solution used contains hydrogen peroxide in a mole ratio to peroxomonosulphuric acid of not more than 1:10; the Caro's Acid solution is introduced continuously or in increments of less than 1 % of the total over a period of at least an hour, the Caro's Acid is produced by reaction between 93-98 % sulphuric acid and 65-72 % aqueous hydrogen peroxide in a mole ratio of 2.7:1 to 3.5:1; the Caro's Acid solution is diluted before use; and particular amounts of Caro's Acid are used depending upon the nature of the nickel/cobalt solution, the mode of treatment, and the nature of the neutralising agent. Further separation can be effected by subsequent water and particularly not acid washing of the precipitate.

Abstract: ABSTRACT       A longitudinally striated coating on a strip article is produced by advancing the article past an open side of an otherwise-enclosed trench so that the article surface to be coated closes the open trench side, while delivering concurrent laminar flows of two different liquid coating materials to the trench at least at one locality spaced from the open side of the trench, to keep the trench completely filled and to deposit a layer of coating material on the moving surface of the article.   Liquid circulation in the trench caused by the motion of the article surface so distributes the two coating materials along the trench that the applied coating layer is constituted of alternating longitudinal striations of the two materials.   With delivery of concurrent flows of the two coating materials at each of plural localities spaced along the trench, positional and  other variations of the striations can be achieved by varying the relative total flows delivered at different ones of these localities, for example to create a simulated wood-grain pattern.

Abstract: Abstract of the Disclosure:          An apparatus for remote monitoring color distribution of two materials charged in a treating column by moving a color sensor along a viewing window of the column.  The color sensor moving along the viewing window projects a light on-to the materials in the treating column and receives the reflected light to convert into a reception signal.  A comparator com-pares the reception signal with the reference signal representing a standard color of the materials in the column to produce a digital color difference signal.  The digital color difference signal is sampled and distributed to indicator lamps in accordance with position signals from the position sensing means which senses the passage of the color sensor by each of a plurality position.  Thus, the indicator lamps provides a remote display of the color distribution of the materials along the viewing window.  Further, operation processing means is provided which checks the inversion frequency of samples of the color difference signal and the inversion position or positions thereof and selectively  produces one of a plurality of control signals each indicating how far the separation process goes.

Abstract: D-23,525 METHOD OF MEASURING SPLICE LOSS IN OPTICAL FIBERS by Joseph Zucker and Arthur H. Fitch Abstract of Disclosure A method of determining splice loss 10 log (1-PR/PO) that is practiced at the location of a splice between one ends of input and output fibers.  A reference level PO of light that is transmitted out of the one end of the input fiber is obtained by inserting it into an integrating cylinder of split block construction, prior to making the splice, and coupling diffuse light in the cylinder to a radiometer.          After the ends of the fibers are spliced together, the splice and a significant portion of the adjacent length of output fiber exhibiting substantial leaky mode radiation that is caused by the splice, is located in the cylinder.  With light or the reference level in the input fiber being incident on the splice, the radiometer provides an indication PR of light lost as a result of the splice.  The indication PR may also be obtained by integrating only light radiated from a length of the leaky mode section of output fiber, which has been found to extend to approximately one foot downstream of the splice.

Abstract: ABSTRACT    A gauging apparatus for sheet materials and the like comprises a surface follower body (14,20,30) adapted to be constrained without substantial solid bodily contact and guided (e.g., by gas bearings between 32 and 36 and 38) for movement along a surface follower path that intersects the path of a traveling sheet (10)  to be gauged.  The body has a passage (46) adapted to carry a flow of pressurized gas to be discharged against one surface of the sheet.  The discharge of the gas is effective when the body is at a predetermined distance from the surface to generate a levitating force (on 20) urging the body away from the sheet surface.  Means (70,64,62) responsive to the pressure of the gas in the passage exerts on the body (at 64) a counteracting force that tends to move the body closer to the surface.  The counteracting force increases when the pressure increases and decreases when the pressure decreases, and coacts with the levitating force in such a manner that the predetermined distance of the body from the surface is normally maintained substantially constant and is relatively unaffected by minor variations in the pres-sure of the gas in the passage.
