Patent GB-541771-A (GB)
Title: Improvements in photographic sound film, particularly combined sound and picture record film
IPC: G03C5/14
Filed: 1940-06-07
Abstract: 541,771. Photographic sound tracks ; combined sound & picture records. KODAK, Ltd. (Eastman Kodak Co.). June 7, 1940, No. 7877/41. Divided out of 10014/40. [Class 98 (ii)] A sound track comprises a mixture of silver sulphide and silver iodide in which, measured to infra-red light, at least 25 per cent of the optical density is due to silver sulphide, and at least 25 per cent to silver iodide. The ratio of sulphide to iodide may be such that (1) at least from 30 to 75 per cent of the said density is due to silver sulphide, or (2) at least from 50 to 75 per cent of the said density is due to silver iodide. The record is preferably formed by acting on a silver halide (bromide or chloride) or other silver salt image with a single bath containing a sulphur compound such as sodium sulphide or thiourea, and an alkali metal iodide, and various examples of such baths are given. For producing a track of uniform density, it may be necessary to use a bath nearly saturated with sulphide and iodide. The track may be formed on a black and white picture film, or on a subtractive colour picture film such, for example, as are formed on multilayer or mixed-grain sensitive material, or on material partly multilayer and partly mixed grain, which may contain image forming dyes or dye-forming substances. The bath may be applied to the track area by an edge applicator, or by immersing the edge of the film therein. The sound track exposure may be made at the same time as the picture exposure, and the processing of the track may be performed directly after the negative development, or, especially in cases in which the picture components are processed seriatim, may be delayed until at least two of the picture components have been formed, the sound track area being meanwhile protected by masking. An example is described in which the sound track is formed in a colour picture film produced as described in Specification 507,841. Specifications 382,506, [Group XXXVIII] 467,614, 500,611, 500,721, 503,752, 503,821, 524,154, 524,554 and 524,555 also are referred to.

Filed: 1938-03-21
Abstract: 500,767. Cyclopentanophenanthrone derivatives. NAAMLOOZE VENNOOTSCHAP ORGANON. March 21, 1938, No. 8658. Convention date, March 22, 1937. [Class 2 (iii)] A method of manufacturing acid halides from cyclopentano-dimethyl-polyhydro-phenanthrene carboxylic acids-17 which may be substituted at the nucleus by hydroxyl, acyloxyl or alkoxyl groups or by ethereal or oxidelike bound oxygen, and may also contain double bonds, consists in acylating or alkylating any free hydroxyl groups and converting the carboxylic group into the acid halide group by known methods, e.g. by treatment with thionyl halide. Any double bonds are preferably saturated with hydrogen prior to formation of the acid halide. The starting materials are preferably 3-oxy-aetio-cholenic acids or the corresponding allocholanic or cholenic acids or derivatives. The so-formed acid halides may be converted into substituted pregnanones-20 or pregnenones-20 by treating them with diazomethane to convert the acid halide group of the side chain into the -COCHNH2 group. The -CHNH2 group may be converted into the hydroxymethyl group by treatment with an inorganic oxy acid or an organic sulphonic acid. The product may' be submitted to prolonged hydrolysis to produce hydroxyl groups in the nucleus and in the side chain. In an example, 3-oxy-aetio-cholenic acid or derivatives acylated or alkoxylated in the hydroxyl group is obtained by the oxidation degradation of 3-oxy-bis-nor-cholenic acid and boiled with pure thionyl chloride to give the acid chloride. If this is treated with diazo methane at -10‹ and allowed to stand, the -COCl group in the side chain is transformed to the -C#<O>CHN2 group. Hydrolysis converts this group to the # group. The amount of diazo methane used determines whether the group in the side chain of the product is -C#<O>CHN2 or -C#<O>CH2 halogen
