Abstract: 545,905. Photographic films. KODAK, Ltd. Sept. 16, 1940, No. 14233. Convention date, Sept, 16, 1939. [Class 98 (ii)] A substratum layer between the emulsion layer and its cellulose ester support comprises gelatine hardened with chromic chloride or chromic nitrate. The ester support may be cellulose acetate, or cellulose acetate propionate, which may be hydrolyzed or fully esterified, and it may, before applying the substratum, be coated with one or more hydrolyzed cellulose ester layers which, if more than one is used, may be successively more strongly hydrolyzed, as described in Specification 510,706. If chromic chloride is used, a strength varying from about to 2¢ per cent of the weight of gelatin, preferably 1 to 1¢ per cent, may be used, the quantity being slightly greater in the case of chromic nitrate. There may be a plain gelatin substratum between the hardened substratum and the emulsion layer. Firmer adhesion of the hardened substratum to the support or to the coating thereon may be secured, without increasing the brittleness of the film or its liability to stripping or frilling, by adding to it, as described in Specification 510,706 for an ordinary gelatin substratum, a proportion of cellulose nitrate or a cellulose organic ester. The hardened substratum may be coated from a solution in water containing organic solvents such as acetic acid, acetone, ethylene glycol monomethyl ether, and methyl alcohol; and the plain substratum from a solution in water containing methyl alcohol with or without acetic acid. The Specification describes tests for determining the precipitation values of cellulose esters, the liability of films to dry or wet stripping, and the brittleness of films ; and refers also to films having gelatin substrata hardened with chrome alum, aluminium chloride, thorium nitrate, zirconium oxychloride, lanthanium chloride, acetonyl acetone, formaldehyde, and diacetyl.

Abstract: 1,164,670. Magnetic structures. INTERNATIONAL BUSINESS MACHINES CORP. 4 Dec., 1967 [15 Dec., 1966], No. 55020/67. Heading H1H. [Also in Division C7] A magnetic alloy film is formed on a conductive substrate by electroplating from an electrolyte containing ions of the alloy constituents by applying one or more current pulses in which the magnitude of the or each pulse is initially significantly greater than the current required for plating the alloy constituents in a desired proportion under equilibrium conditions and in which the magnitude of the pulse is subsequently decreased with time so that throughout the process the proportions of the alloy constituents deposited are constant. Typically the pulse magnitude is decreased to the equilibrium value and is thereafter maintained constant for a period. If a series of pulses is used, agitation of the electrolyte may be effected at the end of each pulse. As described the method is applied to electroplating on to a smooth rolled copper sheet or vapour deposited silver or electroless silver or copper a Ni/Fe alloy. Details are given of current values for obtaining specific thicknesses of specific alloys. Plating is effected in a magnetic field at the centre of a Helmholtz coil. Reference is made to plating ternary alloys NiFeCu, e.g. as in Specification 1,139,987, NiFeCo and a four component alloy NiFeCoCu, all of zero magnetostriction.
