Patent GB-511804-A (GB)
IPC: G03C7/14
Abstract: 511,804. Colour photography. LASSUS ST. GENIES, A. H. J. DE. May 3, 1938, No. 13210. [Class 98 (ii)] To obtain photographs in colour on a lenticular film having several light - sensitive layers superposed on its smooth surface the film is exposed and. developed to form in the layer adjacent the smooth surface a temporary record consisting of several partial images in black and white, and the film is then subjected to partial illuminations directed through the lenticulations to produce in'each of the other layers a latent record of one partial image of the first layer, each partial illumination being followed' by a developing and colouring treatment of the latent record produced by it. In producing the temporary record in the uppermost emulsion layer, the action of the light may be confined to that layer either by a wash-out filter dye or, in copying from an original lenticular film, by, using light to which only that layer is sensitive. For example, a film used for copying may comprises blue, green, and red sensitive emulsion layers 1, 2, and 3, with a removable yellow filter layer between and 2. Records b, g, and r are obtained in layer 1 only by copying with blue or ultra-violet light. This layer is developed but not fixed. By means of red light into the direction of the arrow 4 a copy of the image r is obtained in the layer 3 and developed to bluegreen. Similarly the, image b is copied into the layer 2 by green light in the direction 6 and developed to yellow. The unchanged silver halide in the .image g is illuminatiad by blue light in the direction 5 and developed to purple. Any reduced silver in the secondary images and the whole of the primary image are then dissolved with Farmer's reducer. In an alternative method, the layer 1 is developed by a tanning developer to produce the primary image. One colour component record is then printed into layer 3 as above and coloured by mordanting and tinting. Reduced silver and any remaining silver salts are then removed from this layer by converting the silver to choride and dissolving in ammonia. Layer 2 is sililarly printed and coloured but the silver is not dissolved out. The silver halide in the records in layer 1 from wich printing has taken place are bleckened by directed illumination. This silver and that in laver 2 is then removed with Farmer's reducer leaving only the halide of the last partial image in layer 1. This is then treated for example by colour development. When all the coloured images have been produced, the lenticulations may be removed by varnishing. If desired the film may carry four superposed emulsion layers of which one may be used for temporary record only.

The band may have a portion removed (at 12) from its inner edge to facilitate handling. In use in antibiotic sensitivity testing, the disc-shaped portions are impregnated with antibiotics, for example by dripping solutions of the antibiotics from a series of glass tubes on to the device on a conveyor belt, and the device is laid on a bacterial culture plate. Further antibiotic-impregnated paper discs can be placed inside the ring if necessary. Letters 11 printed on the ring serve for identification of the antibiotics.

Abstract: 1,137,673. Thermonuclear apparatus. M-O VALVE CO. Ltd., J. H. HOLLIDAY and M. T. WHITE. 30 Dec., 1965 [30 Dec., 1964], No. 52829/64. Heading G6P. [Also in Division H1] In a discharge tube - e.g. a high voltage rectifier or the toroidal discharge chamber of a thermonuclear apparatus - in which, in operation, a plasma of a density of at least 10<SP>10</SP> ions or electrons cm.<SP>-3</SP> is produced in close proximity to a member of electrically conductive material, e.g. an electrode or the chamber wall, the conductive material is chosen such that any impurity present therein has a resistivity of less than 10<SP>3</SP> ohm cm. at the normal operating temperature of the member. This avoids the occurrence of unwanted arcing at the surface of the member which can arise due to the capacitive charging up, in operation, of particles of resistive impurity. In a mercury rectifier having a filling of hydrogen at 10<SP>-1</SP> torr, the anode is a hollow molybdenum disc clad with 1mm. thickness of platinum. Other materials referred to as suitable for preparation in the required condition are gold, osmium, iridium, palladium, rhodium, and ruthenium. Oxide impurities may be present if they are such as to be reduced by the gaseous filling of the tube at the temperature of operation to yield material satisfying the required condition.

Abstract: 1365975 Heat relaxing yarns; fluid jets MITSUBISHI RAYON CO Ltd 23 Nov 1971 [7 Dec 1970] 54307/71 Heading D1F Apparatus for continuously relaxing a yarn comprises a feed nozzle device 3 with means defining a yarn feed path 15a and means defining a heating medium nozzle slit surrounding the yarn feed path 15a, a relax tube 6 extending from the nozzle device 3, an accumulation tube 19 extending from said relax tube 6 and having a plurality of openings 20 in the periphery thereof and one open end 19b, an outside box 7 surrounding the accumulation tube 19, a delivery nozzle device 10 with means defining a yarn delivery path 31b and means defining a nozzle slit 32b for blowing a cooling medium around the yarn delivery path, and means e.g. ducts 8, 9 for forcibly exhausting the heating medium and the cooling medium, the said means being conncted to the outside box 7, the cooling medium nozzle slit 32b and the accumulation tube open end 19b. Means may also be provided for naturally exhausting a portion of the heating medium, said means being connected to the box 7. In a further embodiment, the box 7 is partitioned into an upper chamber and a lower chamber, the lower chamber being connected to a heating medium supply conduit. The relax tube 6 and the box 7 may be surrounded by a heater e.g. electric heater, sheating jacket, to minimise condensation when steam is used as the heating medium. Various shapes of accumulation tube are disclosed, and the openings 20 are preferably circular, but may alternatively be in the form of longitudinally extending slits. In use of the apparatus to relax yarn, the yarn is prerelaxed by being sucked into the relax tube 6 by means of heating medium e.g. air or steam, jetted along the direction of advance of the yarn. The flow of heating medium carries the yarn through the relax tube 6 to the accumulation tube 19. The prerelaxed yarn is further relaxed by accumulation in a tensionless condition, the heating medium flowing through the accumulation and also carrying the accumulation through the tube 19. The relaxed yarn is delivered from the open end 19b of the tube 19. A cooling medium, e.g. air, is blown toward the open end 19b along the delivery path of the yarn in a direction opposite to the direction of advance of the yarn. The cooling medium introduced at 21 cools the relaxed yarn while unravelling entanglements and intertwinings of the accumulated yarn preventing overrun of the accumulated yarn from the tube 19. The heating medium and cooling medium are forcibly exhausted via ducts 8, 9 which may be fitted with a damper 22 to control the rate of exhaust.

The material is fed by feed rollers 2, 3 actuated in response to a signal initiated by the leading end of the material; this signal also causes the member 6, e.g. a roller, to be moved to its first position so that the material can be operated on by the cutter 4. Further movement of the material causes it to be engaged by feed rollers 7 at which time the member 6 is moved to its second position so that the material is finally operated on by the cutter 5; one of the rollers 7 may be heated.
