Title: New compositions for use in the manufacture of light-sensitive photographic material
Inventor: AMBLER ARNOLD EDWIN
IPC: G03C1/04
Filed: 1954-02-24
Abstract: 755,987. Light-sensitive photographic composition. IMPERIAL CHEMICAL INDUS. TRIES, Ltd. Jan. 21, 1955 [Feb. 24, 1954], No. 6404/54. Class 98 (2). The composition comprises an emulsion containing as dispersed phase an aqueous gelatinosilver halide emulsion and as continuous phase a solution of a water-insoluble water-permeable cellulose ether and a water-sensitive plasticizer therefor in an incompletely water-miscible solvent. Such plasticizers are partly or wholly soluble in water and in their presence lies the difference from the compositions of Specification 718,404. The dispersed phase may be a normal black and white emulsion or it may contain sensitizing dyes and colour formers. Three such compositions may be coated on film, paper, baryta paper, or paper rubbed with a dispersion of baryta in a solution of ethyl cellulose to produce a multilayer colour film of red-sensitive-cyan colour former, green-sensitive-magenta colour former and blue-sensitive-yellow colour former layer with yellow filter layer beneath the blue-sensitive layer; or three emulsions each containing appropriate sensitizing dyes and colour formers may be separately emulsified with the cellulose ether solution and then mixed and coated to form a mixed-grain layer. The compositions do not froth and may be coated by high-speed methods, as by use of a printing press or otherwise, and dry readily. Processing is by normal methods without the use of organic solvents. In Example 1 a gelatino-silver chloride emulsion is hardened with formaldehyde, emulsified with a solution of ethyl cellulose in benzene, dehydrated with sodium sulphate, mixed with xylene and distilled under reduced pressure to remove about half of the benzene, mixed with sodium dioctylsulphosuccinate as plasticizer dissolved in a little benzene, and then coated, exposed and treated in a hydroquinone developer to produce a black and white image. In a second example the same composition is coated on a paper base rubbed with a dispersion of titanium dioxide in nitrocellulose solution and which may have nitrocellulose on the reverse side. Numerous other water-sensitive plasticizers and incompletely water-soluble solvents for use in the composition are listed. Specification 750,201 also is referred to.

Patent GB-848555-A (GB)
Title: Treatment of aqueous solutions of complex metallic cyanides
Inventor: AVESTON JOHN
IPC: C01C3/11
Filed: 1958-02-18
Abstract: Aqueous solutions of cyanide complexes of metals other than gold are contacted at pH above 7 with a nitrogeneous anion exchange resin containing strongly and weakly basic groups in proportion such that the R ratio of strongly basic to total basic (i.e. strongly plus weakly basic) groups is between 10-75%, thereby effecting preferential absorption of metals other than Cu and/or fe and thereafter recovering from the resin a product having a reduced concentration with respect to Cu and/or fe.  The pH of aqueous solutions, for example residual liquors from the cyanide process for the extraction of gold, containing cyanide complexes of described metals e.g. Ni, Co, Ag, Pd, Pt, Ir, Os, Rh, Mn, or Se together with cyanide complexes of Cu and/or Fe is adjusted to above 7 preferably 8-11, and the solution passed through a bed of resin the R ratio of which may be 40-65% preferably 45-55% and which may be based on a crosslinked polystyrene resin, until Cu and/or fe initially adsorbed are displaced down the column.  Depending upon the desired metal content of the effluent the process may be repeated using a series of columns to effect further absorption.  Recovery of the desired metal values may be achieved by elution or by drying and ashing the adsorbate resin.  Eluting agents specified are aqueous sodium thiocyanate, or aqueous sodium or ammonium nitrate containing sodium cyanide, the desired metal being recovered from the resulting solution by any convenient means e.g. recovery of nickel as nickel cyanide, silver as the metal by electrolysis, or as the cyanide and cobalt as the sodium cobalt cyanide complex. Specifications 808,909 and 808,910 are referred to.

Title: Lead-acid storage battery
IPC: H01M50/494
Filed: 1974-02-07
Abstract: 1434487 Separators for lead-acid batteries KANEBO Ltd 7 Feb 1974 [14 Feb 1973 10 Sept 1973 29 Sept 1973 (3)] 05763/74 Heading H1B [Also in Divisions D1 and D2] A lead-acid storage battery comprises separators 6 in the form of porous sheets made from phenolformaldehyde resin fibres having an average diameter of less than 5 microns. The resin fibres are prepared by melt extracting formaldehyde resin through an orifice into a non-oxidizing atmosphere while non-oxidizing gas is blown against the extruded filaments. The filaments are torn off by the gas and form fine fibres which are cured by treating them with a cross-linking agent such as formaldehyde at a temperature of 60 to 105 C. in the presence of a sulphuric acid and hydrochloric acid catalyst. The fibres may be treated by capping at least part of the phenolic hydroxyl groups of the resin or they may be used as they are. The fibres may be combined with other acid and oxidation resistant synthetic polymer fibres and binder resins may be added to an aqueous dispersion of the fibres which are then formed into sheets in a wet-type paper making machine. The sheets may be impregnated with a solution or emulsion of a synthetic polymer resin. Alternatively, the resin fibres may be embedded in a non-woven fabric by forming the fibres into a wet sheet on the frabric which is placed on the wire net of a papermaking machine and applying suction to embed the fibres in the fabric. As a further alternative the resin fibres may be floated in the air and sucked or blown against the non-woven fabric by compressed air. The electrolyte may be retained in the separator sheets or in a glass fibre mat 2.

Abstract: 677,996. Pipe couplings. MINISTER OF SUPPLY. March 24, 1950 [March 4, 1949], No. 6039/49. Class 99 (i) A sealing sleeve 7 carried in the socket 3 of a pipe coupling makes sealing contact with the spigot member 13, the seal being broken by relative movement of the sealing sleeve and socket as the pipe ends are pulled apart. The sealing sleeve is attached to a sleeve 2 connected by a bellows member 4 to the socket, sleeve and socket being held in the coupled position by balls 6 in aligned grooves 5, 51, the sleeve part 1 of the socket being expansible to allow displacement of the balls when pressure is applied to the interlocked sealing surfaces 10, 101. A ring 12 in the form of a close-coiled spring rolling on the inclined surface 11 of the sleeve 7, contracts the sleeve to break the seal. The sleeve 7 is reinforced by a number of flat rigid members 8 spaced around it and having projections 9, which retain the ring 12, and are engaged by the nose 15 of the spigot during the coupling operation. A valve member 17 secured by a spider 19 to the socket 3 closes the socket when the sleeve 7 is drawn over and contracted on to it during uncoupling. Instead of the balls 6 and resilient sleeve 1, resilient hollow, barrelshaped, nylon rollers, connected by a rubber band, are adapted to engage the grooves 5, 51. Other spring locking devices are described. In a modification the sleeve 1 is slidable manually on the socket 3 to contract the sleeve 7 which is held against axial movement in the socket.
