Title: Improvements in processes of colour photography
IPC: G03C7/18
Filed: 1937-12-03
Abstract: 510,784. Colour photography. KODAK, Ltd. (Eastman Kodak Co.). Dec. 3, 1937, No. 33422. Drawings to Specification. [Class 98 (ii)] In order to correct the imperfect colour rendering, due to deviation from the theoretical value of the transmission of the dyes used, in a subtractively coloured photographic record comprising a plurality of differently colour-sensitized emulsion layers inseparably superimposed on a support, the front layer not being specially colour-sensitized, there is conferred upon one of the layers a sensitivity in a region of the spectrum other than that to which it is predominantly sensitive, this sensitivity being inversely proportional to the transmission of light in this subsidiary region by the colouring matter employed. Thus, in order to compensate for the use of a magenta dye deficient in transmission of blue light, or of a blue-green dye deficient in blue, there is conferred upon the green- and red-sensitive layers, respectively, a sensitivity to blue light, as by using a yellow filter layer which transmits some blue light, under the top, bluesensitive, layer; or a green sensitivity may be conferred, by the use of appropriate sensitizing dyes, on the red-sensitive layer, to compensate for a deficient blue transmission of the bluegreen dye. The green-sensitive layer may be sensitized with 4-phenyl-3-methyl-1<1>-ethylpseudo-cyanine iodide and the red-sensitive layer with an 8-alkyl-, aryl-, or aralkyl-3-4-3'-4' dibenzothiocarbocyanine salt, the reversed images being developed with developers containing diethyl-p-toluylene diamine and having as colourformers 1-(p-nitrophenyl)-3-methyl-5-pyrazolone and 4-ehloro-2-phenyl phenol respectively. The coloured image may also be formed by mordanting or dye bleaching. Specifications 440,032, 440,089, 447,748, 458,665, 475,784, 475,786 and U.S.A.

Filed: 1920-11-26
Abstract: 154,546. Bechler, A. June 9, 1917, [Convention date]. Lathes.-In automatic lathes of the type in which the headstock, and the spindle of the tailstock, are fed by a variablespeed cam shaft, means are provided for changing the ratio of the cam-shaft speeds according to the nature of the work. The cam shaft e having cams b<1>, c<1>, d<1> actuating the headstock, tailstock, and tool slide respectively is driven from a shaft g carrying a loose member i driven by cone pulleys and a second loose member j driven from cone pulleys l through a train of gearing. A lever k actuated by a. cam m slides a feathered clutch portion h to change the speed of the shaft g. Thus, in order to vary the ratio of the cam-shaft speeds, either of the two speeds of the member i may be combined with any of six speeds of the members j obtainable from the cone pulleys l and interchangeable wheels r, r<1>. The headstock is actuated through a double lever, one arm of which is controlled by the cam b<1> and the other by a cam on a shaft q gear driven from the main cam shaft. The cams b<1>, c<1>, d<1> may be readily removed and replaced without dismantling the cam shaft.

Abstract: The invention comprises magnesium thioglycollate HS-CH2-COO-Mg-OOC-CH2SH, the corresponding disulphide <FORM:0858216/IV(b)/1> and their dihydrates.  The magnesium thioglycollate di hydrate may be prepared by reacting one equivalent of magnesium carbonate, magnesium oxide, magnesium hydroxide or basic magnesium carbonate with one equivalent of thioglycollic acid in an aqueous medium, suitably under an inert atmosphere with cooling; the resulting dihydrate may be isolated by concentrating down the aqueous solution and then precipitating the dihydrate by addition of ethanol, isopropanol, acetone or diethyl ether.  The corresponding disulphide may be prepared by oxidising the magnesium thioglycollate in aqueous solution with, for example, a peroxy compound such as hydrogen peroxide, or, alternatively, by reacting in an aqueous medium one mole of dithioglycollic acid with one mole of magnesium carbonate or other above mentioned magnesium base; the resulting disulphide may be isolated in the form of its dihydrate by the method described above for the thioglycollate dihydrate.  Both dihydrates may be converted to the corresponding anhydrous salts by dehydration, for example by azeotropic distillation with xylene.  Examples are given.  The products are stable in air and substantially odourless.  They may be used in hair waving preparations (see Group IV(c))ALSO:Compositions for use in the permanent waving of hair comprise a magnesium thioglycollate of the formula HS-CH2COO Mg OOCCH2-SH, the corresponding disulphide having the formula:  <FORM:0858216/IV (c)/1> or the dihydrate of either, and an alkaline material of low volatility such as sodium or potassium hydroxide or glycinate, sodium N- methyl taurate, or an amine such as 2- amino -2- methyl-1 : 3- propanediol or diiso propylamine.  When employing the disulphide compound there must be present a reducing agent effective to reduce the compound to the corresponding thioglycollate.  The compositions may also comprise metal-complexing agents such as cyclohexanedione dioxime, drying agents such as silica gel, buffering salts, sequestering agents, solubilisers, surface-active agents, oleaginous materials and perfumes.  The compositions may be utilised as powders or lotions or preferably in the form of end papers.  The compositions may be dispersed in the paper or contained in a water-pervious envelope attached to the paper.  The end-papers may be of paper or unwoven bonded webs of cotton or a cellulosic material and may be perforated.  They may be used in conventional manner, the treated hair then being set by aerial oxidation or treatment with the usual oxidisers such as sodium perborate.  An end paper containing the disulphide compound is used in conjunction with a conventional waving lotion, e.g. aqueous ammonium thioglycollate.
