Title: Improvements in processes of colour photography and compositions therefor
IPC: G03C5/38
Filed: 1954-07-19
Abstract: 751,186. Colour photographic processing and compositions. KODAK, Ltd. July 19, 1954 [July 20, 1953], No. 21011/54. Class 98 (2). Blue stain in photographic records or paper prints which have been subjected to a ferricyanide silver-bleaching process is avoided by treatment before or during fixing with a soluble zinc, cadmium or manganese salt. Such salts precipitate ferrocyanide, formed by reduction of the ferricyanide, in an innocuous form and so prevent reaction of the ferrocyanide with traces of iron in processing solutions or washing water to form Prussian blue, which is believed to constitute the stain. The process may be used in conjunction with silver removal after reversal or negative-positive procedure, with colour formers in the developers or in the emulsions, as described in Specifications 507,841 and 541,589. The claims are directed to a dry packaged composition of zinc sulphate, sodium sulphite and hypo, and to compositions including similar materials together with an acid such as acetic acid, as well as to the feature of processing method concerning the zinc, cad. mium or manganese salt treatment.

Filed: 1969-04-24
Abstract: 1,270,293. Television; optical ranging. COMPAGNIE GENERAL D'ELECTRICITE. 24 April, 1969 [25 April, 1968], No. 21105/69. Headings H4D and H4F. In a line sequential television camera e.g. for scanning the ground from an aircraft, in which a continuous laser beam is reflected by a rotating mirror 10 to scan along a line on the ground at 90 degrees to the direction of movement of the aircraft and the light reflected therefrom is concentrated in a focal line in the camera, a bundle of optic fibres has inlet faces disposed along the focal line and outlet faces disposed along an arc of a circle, and a cranked light guide 7 is rotated synchronously with the laser scanning so that its inlet end scans the arc of optic fibres and its outlet end on the rotational axis delivers light to an adjacent photomultiplier 4. By controlling the width and speed of the inlet of the guide 7, and the phase of its scanning motion relative to the laser scan, spurious echoes, e.g. from clouds, above a predetermined height, may be ignored since they will be transmitted through an optic fibre before it is reached by the guide 7. At the focal line, the ends of the fibres may be parallel, but are preferably inclined so as to be parallel to the direction of the appropriate incoming light rays, Fig. 4b (not shown). Parallel mirrors, perpendicular to the focal line, may be disposed adjacent the rear of fibre inlets to increase the effective length of the focal line by reflecting light from the ends of the scanned line towards the fibre inlets, Fig. 4a (not shown). In the embodiment of Fig. 4d, mirrors 5 and 6 are perpendicular to the focal line but are mutually inclined so that light from the ends of the scanned line is reflected to enter fibres 2 forming two rows at an angle to the main row of fibres 20 which receives directly transmitted light and lies on the focal line, Fig. 4c (not shown).
