Title: Method for producing Balanced Colour Prints in Photgraphic Printing
IPC: G03B33/00
Filed: 1967-02-14
Abstract: 1,183,601. Photographic colour printing; colour charts. HEATH CO. Feb.14, 1967 [Feb.21, 1966], No.6966/67. Headings G2C and G2J] The filter needed for preparing a coloured balanced colour print on sensitive material from a colour negative utilizing photographic printing equipment, is selected by (i) preparing a negative having an area of known colour characteristic, (ii) preparing a colour print of the area on the sensitive material, (iii) selecting a colour balance which includes an area of the known colour characteristic and has reference colour cast areas of known density and of the known colour characteristic modified by supplementary known amounts of one or more other colours, (iv) comparing the printed area with the balance standard and selecting a reference colour cast area matching the printed area, and (v) selecting a filter corresponding to the known supplementary amount of the one or more colours in the selected colour cast area. Preferably the area of known colour characteristic is a neutral area, the negative being formed by photographing the colour balance standard or by developing an unexposed negative film, and the colour print to be compared with the standard is prepared using a neutral density step wedge to facilitate matching. The colour prints may be formed using a colour bias filter which approximates to the typical requirements for correction and facilitates calibration utilizing only yellow and magenta filter media. The area of known colour characteristic may alternatively be white, flesh-coloured or of any other colour. The colour-balancing standard 10 used has a neutral background area, and a neutral central area 12 surrounded by a plurality of coloured areas having a substantial neutral density. The centres of the coloured areas lie on radials I to XII of four concentric circles A to D; each area on a single radial has the same colour, and each area on a single circle has the same density of colour, this density increasing with the radius of the circle.

Title: Improvements in or relating to the purification of gases intended for the manufacture of hydrogen for use in the synthetic production of ammonia
IPC: C01B3/02
Filed: 1924-03-26
Abstract: Gases such as water gas and coke oven gas employed as a source of hydrogen intended for the synthesis of ammonia are freed from carbon dioxide and sulphuretted hydrogen by scrubbing with an ammoniacal liquor produced in an ammonia-soda process of the Schrieb type, and the solution of carbonate and sulphur compounds thereby obtained is subsequently utilized in said process.  In the Schrieb modification described in Specification 160,172 the liquor used for purifying the gases is that obtained by adding ammonia or alternatively, ammonia and salt to the mother liquor obtained after separation of ammonium chloride.  In the case of the Schrieb modification described in Specification 131,870 the mother liquor resulting on precipitation of sodium bicarbonate is employed after addition of ammonia and sodium chloride; or sodium chloride is added to the same mother liquor and ammonia added after ammonium chloride has been separated by cooling. Purification may be effected before or after compression of the gas which is caused to pass up towers packed with Rasching rings, plates, &c. irrigated with the ammoniacal liquor.  Since ammonia escapes with the purified gas, the latter is passed up packed towers irrigated with water or sulphuric acid, yielding, in the latter case ammonium sulphate which is separated by crystalization.
