Title: Manufacture of nitrogen-containing derivatives of the benzanthrone series
Filed: 1929-03-13
Abstract: 333,882. I. G. Farbenindustrie Akt.- Ges. March 13, 1929. Divided on and addition to 307,926, under which a Specification was laid open to inspection under Sect. 91 of the Acts, March 18, 1929]. Dibenzpyrenequinones.-Mononitro derivatives are obtained by nitrating dibenzpyrenequinones under milder conditions than those described in the parent Specification, for example, by nitrating at a lower temperature, or for a shorter time, or with a smaller proportion of nitrating agent. The nitration is preferably conducted at a temperature of 30-140‹ C., in the presence of a diluent. The corresponding monoamino derivatives are obtained on reduction. In examples, (1) 4 : 5: 8 : 9- dibenzpyrene-3: 10-quinone is treated with a mixture of nitric acid and nitrobenzene in a ball mill at ordinary temperature, or with the calculated quantity of nitric acid in nitrobenzene at a raised temperature; the mononitro derivative obtained is reduced to the monoamino derivative, and (2) 3 : 4 : 8 : 9-dibenzpyrene-5 : 10-quinone is treated with nitric acid in nitrobenzene. Specifications 285,502, 318,180 and 324,964 are referred to.

Title: Improvements in and relating to the production of carbon monoxide and gaseous mixtures containing it
IPC: C01B32/40
Filed: 1944-06-02
Abstract: 582,055. Water gas plant. ARNOLD, M. H. M., PRYDE, D. R., MORLEY, R. J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 2, 1944, No. 10603. [Class 55 (i)] Carbon monoxidecontaining gases are produced from powdered carbonaceous material by treatment with gases at such a velocity as to maintain the particles in fluid state without causing their entrainment in the gases withdrawn; blow and make stages are effected in separate vessels. Coal in fluid condition may be initially carbonized in a retort or in the upper part of the blow vessel. In a three stage continuous process powdered coal is carbonized in a retort 3 whilst maintained in fluid state by passage through it of retort gases at a rate of 10 cubic metres per hour, the carbonized particles at 800‹C. leaving through a pipe 8 and injected with an air stream at 500‹C. through a pipe 10 into a blow vessel 9 in which they are raised to incandescence. Blow gases escape through a pipe 12 from a storage vessel 11 into which the material overflows. A portion returns to the retort supplying heat for the carbonization and another flows into a "make" vessel 15 supplied with steam at 500‹C. through a pipe 16. Water gas is delivered through pipe 17 and residual solid material conveyed by an air stream back to the blow vessel. Specifications 310,686, 317,470 and 321,422, [all in Class 55 (i)], are referred to.

Title: Improvements in colour photography
IPC: G03C7/30
Filed: 1943-07-08
Abstract: 572,227. Colour photography. KODAK, Ltd. (Eastman Kodak Co., and Vittum, P. W.). July 8, 1943, No. 10892/45. Divided out of 571,344. [Class 98 (ii)] Superimposed photographic records in different colours on a single support are produced by developing an upper layer containing silver salt, but no colour coupler superposed on a layer containing colour coupler with a developing solution containing dissolved colour coupler and sufficient of a loading agent such that the colour developer does not penetrate to the underlayer during the time required to colour develop the upper layer. The material may comprise three differentially colour-sensitive silver salt emulsions, one of which is in the form of an upper layer free from colour coupler and the others both contain colour coupler adapted for colour development. The layers may be sensitive to three of the spectral regions, blue, green, red and infra-red. In example 1, a support is successively coated with a redsensitive gelatino silver bromide emulsion containing fine discrete particles of waterinsoluble water-permeable binder or oil-former containing a blue-green coupler, a greensensitive emulsion containing fine discrete particles of water-insoluble water-permeable binder or oil-former containing a magenta coupler, a yellow filter layer, and a bluesensitive emulsion. The exposed material is developed in a colour developer containing a loading agent, e.g. a yellow developer comprising 2-amino-5-diethylaminotoluene hydrochloride, sodium sulphite, sodium carbonate, acetoacetanilide, acetone, isopropyl alcohol and water, to develop only the top layer and then in a developer not containing coupler, e,g. 2-amino-5-diethylaminotoluene hydrochloride, sodium sulphite, sodium carbonate, potassium bromide and water to develop the lower two layers. In example 2, the same exposed material is developed in a developer not containing coupler to develop all three layers, the unused silver halide is removed by fixing, the developed silver is bleached, and the top layer is developed with a colour developer containing a loading agent. In example 3, the same exposed material is developed and fixed as in example 2, the developed silver in the top layer only is bleached with a bleaching bath containing a loading agent, and is developed with a colour developer containing a loading agent. In all examples, remaining silver or silver halide is finally removed. Dispersions of dye-solvents may be incorporated in the sensitive material as in Specification 571,344. Specifications 427,518, 454,499, 454,622, 524,154, 524,554, 524,555, 540,368 and 541,589 also are referred to.

Title: Improvements in method of making therapeutic preparations for subcutaneous or intramuscular injections
IPC: A61K31/43
Filed: 1947-04-25
Abstract: In making a therapeutic preparation for subcutaneous or intramuscular injection containing a water-soluble medicine and an agent for retarding the release of the medicine.  The retarding agent is made by preparing an aqueous solution of pharmaceutical gelatine and dextrose in proportions of from equal parts by weight to 2 1/2 times as much gelatine as dextrose and of a strength of 5-16 per cent by weight of gelatine, and heat-hydrolizing the mixture to reduce the viscosity of the solution so that it has 40-70 per cent of the viscosity before heating.  The solution may be dehydrated, the medicines being combined with the dried mixture; or the medicine may be dissolved in the solution, the whole mixture being then dehydrated for storing and future use upon resolution.  The dehydration may be effected under vacuum while maintaining the temperature below the congealing point to prevent foaming; or while the solution is frozen. The pH may be controlled at values between 5 and 7 depending on the medicine.  Specified medicines are penicillin, streptomycin and heparin.  Vasoconstrictors such as ephedrin sulphate, epinephrin hydrochloride and neosynephrin hydrochloride and local anaesthetics such as eucupin hydrochloride chlorbutanol and procaine hydrochloride may also be added.  Preferably, the gelatine employed has an electric charge opposite that of the p  therapeutic agent.
