Abstract: 1,186,711. Direct positive emulsions. EASTMAN KODAK CO. March 10, 1967 [March 11, 1966, Jan.17, 1967], No.11291/67. HeadingG2C. Direct positive silver halide emulsions comprising fogged silver halide grains are characterised in that (i) at least 80% by weight and/or at least 80% by number of said grains are constituted by crystals free from twin-plane stacking faults i. e. the grains are regular and (ii) an electron acceptor is adsorbed on the surface of said grains. The emulsions may be mono disperse as described in Specification 1,186,712. The grains may be fogged so that they satisfy the chemical bleach test of Specification 1,186, 713 e.g. with a noble metal and reduction fogging agent. Specified reduction fogging agents are thiourea dioxide, hydrazine, tetra (hydroxymethyl) phosphonium chloride, stannous chloride, triethylene tetramine diethylene triamine, spermine and bis (#-amino ethyl) sulphide and its water-soluble salts. Specified noble metal fogging agents are potassium chloroaurite, potassium aurithiocyanate, potassium chloroaurate, auric trichloride and 2-auro sulpho benzo thiazole methochloride, and ammonium hexachloropolladate. The electron acceptor may spectrally sensitize in the range 480mÁ - 800mÁ as described in Specification 1,186, 714 e. g. where A and B represent A-L=L-L=B a 2- aromatically substituted indole nucleus, attached to the methine chain through the 3-carbon atom of the indole nucleus and # is a methine group, dyes as described in Specification 1,186,716, other methine dyes containing pyrrolo pyridine, indole, pyrazole and imidazo [4, 5-6] quinoxaline nuclei, and cyanine and merocyanine dyes containing nitro substituents. The electron acceptors specified also include halogenated cyanines as described in Specification 1,186,715 and many other compounds e.g. 5-mnitro benzylidene rhodanine. The emulsions may contain incorporated developers and may be used in a negative silver dye bleach process or dye developer transfer processes. The emulsions are prepared by a procedure in which an aqueous solution of a silver salt and an aqueous solution of a halide are simultaneously run into a solution of a protein peptizer at a pH less than 4 and a pAg of 7.1 to 9.2.
Patent GB-785723-A (GB)
Title: Process of electrolysis of aqueous electrolytes for producing bromine and iodine
Inventor: SCHACHTER OZJASZ
IPC: C25B1/24
Filed: 1955-04-20
Abstract: 785,723. Electrolytic production of bromine and iodine. MAKHTSAVEI ISRAEL. April 20, 1955, No. 11450/55. Class 41. Aqueous bromide and iodide solutions are continuously electrolysed without anodic evolution of gas in a cell without a diaphragm between anolyte and catholyte while feeding fresh electrolyte into the electrochemically neutral zone between the anolyte and catholyte. Preferably, the aqueous electrolyte contains magnesium halide as well as an alkali metal bromide or iodide so that part of the cathodic product is magnesium hydroxide. If the electrolyte contains chloride also, the feed of fresh electrolyte and the electrolysis is regulated so as to produce an aqueous solution of bromine or iodine and, if magnesium ions are present, so as to convert the major part of the cathodically formed alkali hydroxide into alkali halide with simultaneous formation of magnesium hydroxide. In the absence of insoluble hydroxide, the current efficiency falls, calcium hydroxide giving a lower efficiency than magnesium hydroxide. The electrolysis may be carried out in a U-tube with electrodes and catholyte and anolyte overflows in the side limbs and an electrolyte supply in the bend, the supply and overflow tubes being provided with cocks. The iodine and bromine produced are recovered by solvent extraction. In the practical embodiment shown, the cell comprises an upright cylindrical vessel 17, a coaxial inner cylindrical chamber 24, a sleeve-shaped cathode 37 between them and an anode 32 within the chamber, a receptacle 22 beneath the anode chamber 24 and an annular passage between them through which the anode chamber communicates with the cathode chamber, anolyte and catholyte drains 42, 43 at substantially the same upper level in the cell and a sediment drain 44 at the bottom of the cell, and an electrolyte feed pipe 40 opening into the receptacle. The anode may be a graphite rod carried by a cap 34 insulated from a tube 31 on the lid 26 of the chamber 24 which is axially displaceable by a rod and nut connection to the cell cover 29. The cell is surrounded by a cooling water jacket having an inlet 19 and an outlet 20.
