Title: Improvements in the manufacture and production of vat dyestuffs containing nitrogen
IPC: C09B5/06
Filed: 1928-12-19
Abstract: 326,268. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Dec. 19, 1928. Anthraquinone vat dyes.-N : 2-Pyrazolanthronyl benzanthrones which have a negative substituent in the Bz1-position and the 2 position in the pyrazolanthrone radical free, are obtained by condensation of a 2-halogen benzanthrone negatively substituted in the Bz1-position with a pyrazolanthrone not substituted in the 2-position. By treatment with alkaline condensing agents they are converted to new vat dyes, from which dyes of other shades are obtained by halogenation, preferably in an organic solvent and in the presence of halogenating catalysts. According to examples, (1) N : 2-pyrazolanthronyl-Bzl-nitrobenzanthrone is obtained from pyrazolanthrone and 2-chlor-Bz1-nitrobenzanthrone (prepared by nitrating 2-chlorbenzanthrone) and fused with alcoholic potash; (2) the product obtained by (1) is treated in nitrobenzene with sulphuryl chloride in presence of pyridine; (3) N : 2-pyrazolanthronyl- 6 - Bz1-dichlorbenzanthrone is obtained from pyrazolanthrone and 2 : 6-Bz1-trichlorbenzanthrone (prepared by vigorous nitration of 2-chlorbenzanthrone, and chlorinating the dinitro derivative so obtained) and fused with alcoholic potash; (4) 2 : N-4<1>-benzoylaminopyrazolanthronyl - Bz1-nitrobenzanthrone is obtained from 4-benzoylaminopyrazolanthrone (prepared by treating 1-chlor-4- benzoylaminoanthraquinone with hydrazone) and 2-chlor-Bz1-nitrobenzanthrone and fused with alcoholic potash; these products dye cotton in violet shades.

Title: Apparatus and method for binding compiled routines

Filed: 1972-08-18
Abstract: 1358018 Digital computers; binding compiled routines BURROUGHS CORP 18 Aug 1972 [2 Sept 1971] 38615/72 Heading G4A An apparatus and method are disclosed for binding precompiled program routines as required by a host program. Many standard subroutines are stored in machine language (object code) and, when a host program is being compiled, those subroutines forming part of the host program are fetched by a binding program and integrated with the compiled version of the host program. In this case the program routines are in recursive (re-entrant) form, i.e., a program which has the facility to call or re-enter itself (see Fig. 2D where routine X(Y1) calls X(Y1) in its routine). The program is organized into a number of nested levels (see Fig. 1). Each of the subroutines and the host program is provided with a segment dictionary or list of subroutines required by that routine. A pass is made through the dictionary for the host program and, when a precompiled subroutine is discovered, the binding program calls itself to search for any subroutine object codes called for by the now parent subroutine and so on. When no lower level codes are found, then the program searches for further precompiled subroutines in the same way. Two passes are made through each segment dictionary. On the first pass a search is made for any descriptors referencing missing routines. During the second pass the required changes to the object code are made and the new host program file is created. The computer (Figs. 3 and 4, not shown) includes one or two stack orientated (first in, last out) processors, two memory modules, a card reader and magnetic disc and tape units. The precompiled subroutines, the binder control data and the host file are entered by way of the card reader and stored in the disc file, where the created host program file is also stored.

Abstract: 844,865. Photographic colour materials. KODAK Ltd. Dec. 21, 1956 [Dec. 23, 1955], No. 38987/56. Class 98(2) A water-insoluble colour coupler containing at least one acid group is incorporated into a photographic organic hydrophilic colloid by dissolving the coupler in an organic liquid which is completely miscible with water, adding water to the resulting solution in the presence of a dispersing agent so as to precipitate the coupler as a dispersion, removing the organic liquid from the resulting dispersion and then mixing it with the hydrophilic colloid. The organic liquid may be acetone, methanol, ethanol, acetonitrile, dimethyl formamide or dioxane and the hydrophilic colloid may be gelatin or the phthalic anhydride gelatin of Specification 649,544. The dispersing agent, if oil-soluble, may be added as a solution in an organic solvent to the coupler solution before water is added, or if watersoluble, may be included in the water which is added. In the examples, a 1 % acetone solution of Alkaterge-C (e.g. a condensate of 2-amino-2- methyl-1; 3-pentane-diol with oleic acid) is added to the coupler solution before the water is added, and in some cases also the dioctyl ester of sodium sulphosuccinic acid (aerosol OT) is mixed with the water to be added. Packets may be prepared by adding a gelatino-silver halide emulsion to the dispersion of. coupler in the hydrophilic colloid and then adding the ammonium salt of styrene/maleic anhydride copolymer alone and stirring, or adding also a copolymer of methyl a-methacrylate and methacrylic acid and stirring (see Specification 711,488). Examples are given of the preparation of such packet emulsions and of the mixing of such packet emulsions containing different colour couplers. The colour couplers may be the resin couplers described in Specification 767,028 or the couplers of Specification 733,119 or U.S.A. Specification 2,688,544. Specification 541,589 also is referred to.
