Title: 1-benzoxacycloalkanes and methods of preparation
IPC: C07D499/00
Filed: 1962-06-06
Abstract: The invention comprises compounds of the general formula: <FORM:0947127/C2/1> in which Ph is phenyl, n is 1,2 or 3, and R is a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms. Compounds in which R is alkyl are prepared by reacting equimolecular proportions of an alkali metal 3-phenyl-2-benzofuranone and a dihaloalkane of formula X-(CH2)n-X, in which X is chlorine or bromine, in an inert organic solvent at 0 DEG C. to the reflux temperature to obtain the intermediate 3-haloalkyl-3-phenyl-2-benzofuranone which is then reacted with an equivalent amount of alkali metal alkoxide at room temperature to the reflux temperature.  For compounds in which R is methyl or ethyl the reaction may take place in one step by refluxing one molecular proportion of each of 3-phenyl-2-benzofuranone and a dihalomethane or dihaloethane with two molecular proportions of an alkali metal alkoxide. Compounds in which R is hydrogen are prepared by reacting a compound selected from <FORM:0947127/C2/2> and <FORM:0947127/C2/3> in which R1 is an alkyl group having from 1 to 4 carbon atoms, with an alkali metal hydroxide in the presence of alcohol or water as solvent, at from about 23 DEG C. to the reflux temperature and then acidifying to precipitate the product. Numerous examples of compounds produced are given.  The acid compounds may be further converted to the chloride and reacted with 6-aminopenicillanic acid or an amino alcohol.

Title: Colour photography
IPC: G03C7/18
Filed: 1948-08-20
Abstract: 652,953. Colour photography. GANQUIN, K. O., HADDOCK, N. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 20, 1948, No. 22000. [Class 98 (ii)] A colour corrected multicolour record is made by colour developing an exposed multilayer film comprising a base and superimposed thereon three differently sensitized gelatinosilver halide emulsion layers containing respectively a cyan colour former, a magenta colour former, and a yellow colour former which contains in its molecular structure the grouping -CO-CH 2 -CO- as part of an open chain of atoms, treating the film before, during or after the removal of silver with a gelatin hardening agent, and treating the film with a solution of a diazonium compound after the treatment with a gelatin hardening agent. The hardening treatment prevents residual yellow colour former from reacting with the diazonium compound, but the residual cyan and magenta colour formers do so react to form correcting masks of azo dyestuff. Suitable yellow colour formers are p-stearoylaminobenzoylacetanilidep-carboxylic acid, p-methoxybenzoylaceto-(2-N- octadecyl - N - methylamino) - 5 - carboxyanilide and p - stearoylaminobenzoylacetanilide - 3: 5- dicarboxylic acid. Potassium or chrome alum or image-wise tanning agents as used in the " carbon " and similar processes may be used as hardening agents. The diazonium compounds may be made by diazotizing the parent bases, or may be prepared from any available form of stabilized or passive diazonium compound. Positive or negative multicolour pictures, developed if desired by reversal, may be produced, particularly coloured negatives suitable for printing. Five examples illustrate the process using known couplers and other substances; example 1 describing direct colour development of the exposed film, treatment of this in a combined tanning and bleaching bath of aqueous potassium-ferricyanide, -bromide, - dichromate, -alum, and acetic acid, and then in the zinc chloride double salt of p-nitrobenzene diazonium chloride, followed by fixing, to produce a negative. Example 2 describes exposure of a film to a colour negative or positive transparency which may be colour corrected or not, development to black and white, bleaching with ferrocyanide and sodium chloride to convert developed silver to silver chloride, removal of this with sodium sulphite, re-exposure of residual silver bromide, colour development, and treatment with a diazo compound such as that derived from 4-nitro-6- methoxy-aniline to produce a negative or positive. Examples 3 and 4 describe application of the method to films containing reduced amounts of the cyan and magenta colour formers to avoid undesired reaction of such with the diazo compound used, and example 5 describes another direct colour development process of the nature of example 1, but using separate tanning and bleaching baths followed by mask production with the zinc chloride double salt of 2-nitro-4-methoxy-benzene diazonium chloride and fixing. Specifications 465,823, 502,665 and 602,881 are referred to.

The front part of the sleeve 17 is reduced in diameter and is engaged in an aperture formed in a back jaw mounting plate 19. A circular recess is formed in the plate 19 for the locating plate 14 from which there extend three locating studs 15. The recess is provided with three pairs of holes 20 of which either one or the other set of three holes may be engaged by the three locating studs 15 of the plate 14. Fitted slidably within the sleeve 17 is a sleeve 22 in which there is formed a longitudinal keyway 23. A key 24 engaged in registering radial apertures through the back jaw mounting plate 19 and the sleeve 17 has its inner end engaged in the keyway 23 to restrain the sleeve 22 against rotation relative to the sleeve 17. A spindle 30 engages rotatably but non-slidably in the inner sleeve 22 and has a threaded portion 34 engaging a nut 35 which projects through a rectangular-section aperture 18 formed in the outer sleeve 17. If it is desired to bring any one pair of jaws uppermost to a substantially horizontal position, the front jaws are first moved a short distance in advance of the back jaws by rotating the vice handle 32. This causes the nut 35 to move rearwardly in the oversize aperture 18 of the outer sleeve 17. The back jaw mounting plate 19 is then grasped and moved forwardly, so that it is disengaged from the locating studs 15, after which it, together with the front jaw mounting plate 25, may be rotated to the appropriate position. The back jaw mounting plate is pressed rearwardly so that the locating studs 15 re-engage in holes 20 in the back jaw mounting plate 19. In similar manner, the back jaw mounting plate and with it the front jaw mounting plate may be moved so that any selected pair of jaws is brought in off-set operative position, to one side of the vice and substantially vertical.
