Title: Silver halide colour photographic light-sensitive materials
IPC: G03C1/22
Filed: 1969-09-16
Abstract: 1,274,077. Silver halide colour photographic light-sensitive material. FUJI PHOTO FILM CO. Ltd. Sept. 16, 1969 [Sept. 16, 1968], No.45631/69. Heading G2C. A colour photographic light-sensitive material comprises a support having coated thereon a redsensitive silver halide emulsion layer containing a cyan-colour forming coupler, a green-sensitive silver halide emulsion layer containing a magentacolour forming coupler, and a blue-sensitive silver halide emulsion layer containing a yellow-colour forming coupler and a compound represented by the general formula:- wherein R represents a sulphoalkyl group or a sulpho-atalkyl group each in acid or salt from, and Z and Q each represent the non-metallic atoms required to complete a heterocyclic nucleus. The amount of said compound added is preferably 0À01 to 0À5 g per mole of silver halide. Z preferably represents the atoms required to complete a benzothiazole, benzoselenazole, benzoxazole, α-naphtho-thiazole, α-naphthoxazole or #- naphthoxazole nucleus. Q preferably represents the atoms required to complete a rhodanine, 2-thio-2, 4 -oxazoledione, or 2-thio-hydantoin nucleus. The material of the present invention gives a true yellow dye image, since the compound defined above does not spectrally sensitize the emulsion to the longer wavelength region (beyond 530mÁ).
Patent GB-457656-A (GB)
IPC: G03C7/14
Abstract: 457,656. Colour and stereoscopic photography. LASSUS SAINT GENIES, A. H. J. DE, 3, Boulevard de Roi, Versailles, France. April 30, 1935, Nos. 12927 and 12928. Convention dates, May 4, 1934 and July 17, 1934. [Class 98 (ii)] In a method of copying lenticular films by projection all the elementary beams emanating from the original film are explored successively by a copying optical system of small aperture and transmitted successively to the copy film, the two films, the lenticulations of which face, being animated, with respect to the centre of the optical system, bv translational or rotational homothetic movements such that the macroscopic image remains stationary on the copy film and that the planes of the two films remain conjugated in the optical system during copying. As shown, the lenticular film AB is copied on to the lenticular, film A<1>B<1> by the optical system 0, the lenticulations of the two films facing. The objective O is stopped down either by a slot for cylindrical lenticulations or by an orifice for spherical lenticulations. Appropriately apertured screens D and D1 are provided. The apertures of the screen D has the same contour and occupies the same relative position as the taking colour filter for colour photography or as the diaphragm used for stereoscopic photography. The film AB may be plane or cylindrical during copying, and auxiliary lenses may be employed. The optical system 6 and the film A<1>B<1> are continuously oscillated. Additional screens R and R<1> may supplement or replace the screens D and D<1>. Either the original or copy films or the optical system may be fixed, and the other two elements movable. In a modification an additional optical system is placed in the plane of the screen D. The macroscopic image may be inverted by a prism or by a mirror, or an optical inverter system may be employed. In the latter case both the films may be maintained stationary. The light source may also be moved.

Abstract: 1275,670 Evaporation of solvent from polymer solutions or slurries SUMITOMO CHEMICAL CO Ltd 19 Sept 1969 [21 Sept 1968] 46206/69 Heading BIB [Also in Division C3] A rubber-like polymer of high molecular weight is recovered from a solution or slurry thereof in an organic solvent by feeding the solution or slurry through nozzle 114 into the lower part of a column 106 which is filled with heated water whereby the solvent vaporizes and causes the mixture to rise up the column and the polymer to separate, in the form of crumbs, at the top; the crumbs are removed by conveyor 110, while the water circulates through downpipe 108 to the lower part of the column 106, no pump being necessary. The temperature of the water is adjusted, e.g. at 100‹C, by injecting steam into column 106 through pipe 16a. A solution or slurry from a polymerization process is fed from line 1 to mixer 102, water being added through pipe 10. The solvent and water vapours from the top of column 106 are supplied to mixer 102 through pipe 6. The vapours condense in the solution or slurry, and the hot mixture flows to evaporator 103 where part of the solvent and water vaporize spontaneeously as an azeotrope, the vapours being condensed in cooler 112, and the condensed solvent being separated from the condensed water in tank 113. Water separated in the lower part of evaporator 103 may be discharged through pipe 13, or it may be recycled to mixer 102 through pipe 12. The concentrated solution or slurry withdrawn from evaporator 103 through pipe 4 is pumped through mixer 105 to column 106, hot water being added, if necessary, through pipe 15. Examples 1 and_ 2 relate to the recovery of ethylene/propylene copolymer from heptane solution. Example 3 relates to the recovery of polybutadiene from toluene solution.

Abstract: 1,119,726. Delivering measured quantities of liquid. WALKER MFG. CO. 3 Nov., 1965, No. 46634/65. Heading B8N. A device 10, Fig. 1, for dispensing measured quantities of liquid comprises metering means 28 for metering liquid from a reservoir 12 to a dispensing chamber 46 and valve means 40 selectively communicating an actuating fluid with the chamber whereby the liquid is dispensed from the chamber. The metering means 28 comprises a diaphragm 92 held between a cover 94 and a housing 62 thereby defining two chambers 128 and (100, Fig. 5); the diaphragm is formed with a seating 106 surrounding an outlet port 108 and adapted to co-operate with a ball valve 90 located in a resilient sleeve 86. The liquid in the container is pressurized by air fed via a pipe 34, pressure regulator 36 and pipes 38, 18. In operation, liquid is fed through a pipe 26 and inlet 72 into the housing 62 and thereby forces the ball valve 90 against the seat 106 so that the chamber 128 fills. Upon rotation of a cam 48, a switch 50 is actuated thereby energizing a solenoid in the valve means 40 and permitting compressed air to pass via passages 124, 114, 108 so as to force the ball valve off the seat 106 and allow the liquid in the chamber 128 to enter the chamber 100. When the valve 40 is de-energized the pressurized liquid again enters the chamber 128 thereby forcing the liquid in the chamber 100 into the dispensing chamber 46 from where it is forced out during the next operation, by air fed through a pipe 44.

The square 26 is rotatably supported on a shaft 7, adjacent a disc 9 rigid with the shaft, and is normally clamped to the disc 9 by a screw 28 in the end of the shaft. The screw is provided with an operating lever 29. The head 1 is carried by a disc 5 integral with a bracket 2 movable along a guide member of the machine. Shaft 7 is rotatable in a bush 6 on the disc 5, and has a knob 13 rigidly secured to its upper end. Balls 8 recessed in the disc 5 are engageable with recesses 10 in the disc 9 to form the detent device. The recesses 10 are at 5 degree pitch round a pitch circle coaxial with the shaft 7. A stop 30 on the square 26 engages an arcuate slot 31 in the disc 9 to limit relative rotation therebetween to 7 degrees 30 minutes. In use, to release the rotatable assembly for positive adjustment through an angle which is a multiple of 5 degrees, a button 23 is pushed radially inwards so that a wedge 22 thereon pivots a lever 18 about an axis normal to the shaft 7 against an abutment 15 to move a washer 14 downwards, the thrust being transmitted by balls 16 to the disc 9 to move the rotatable assembly downwards to release the detent device, the assembly then being rotatable by the knob 13. A spring returns the button 23 when it is released, the wedge 22 acting between the knob 13 and an insert 25 above the bush 6 to raise the rotatable assembly and re-engage the detent device. Release of clamping screw 28 allows adjustment of the square 26 relative to the disc 9, a full movement from one limit to the other giving positive setting in the half pitch position.
