Title: Improvements in and relating to colour photographic light-sensitive silver halide material
IPC: G03C7/36
Filed: 1969-05-20
Abstract: 1,247,786. Reversal colour photographic light-sensitive silver halide material. FUJI PHOTO FILM CO. Ltd. May 20, 1969 [May 20, 1968], No.25619/69. Heading G2C. A multi-layer reversal colour photographic material of a type to be developed in colour developers containing diffusible couplers respectively comprises a support having thereon a redsensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer, wherein either (1) only said blue sensitive silver halide emulsion layer contains a coupler, the coupler contained being a diffusion-resisting yellow coupler or (2) the said blue-sensitive layer contains a diffusion-resisting yellow-coupler in an amount of 0.0005 to 0À5 mole per mole of silver halide in the blue-sensitive silver halide emulsion and wherein one of the red- or green-sensitive layers optionally contain a diffusion-resisting cyan or magenta coupler respectively. The invention also comprises a process for preventing the colour contamination caused by mixing of cyan or magenta dye in the blue-sensitive layer of a colour photographic light-sensitive material having on a support at least a red-, a green- and a blue-sensitive silver halide emulsion layer in colour developments performed after black and white development with the successive use of colour developers containing respective diffusible couplers for cyan, yellow and magenta, which comprises incorporating a diffusionresisting yellow-coupler into said blue-sensitive layers and optionally a diffusion-resisting cyan or magenta coupler into one of the red- or greensensitive layers respectively. The diffusion-resisting yellow-coupler preferable has the formula:- wherein R 1  is a tertiary alkyl group, an unsubstituted or substituted cycloalkyl group, an unsubstituted or substituted bicycloalkyl group, or an unsubstituted or substituted aryl group; R 2  is an unsubstituted or substitued aryl group, or an unsubstituted or substituted heterocyclic group; and X is H or a group capable of being split off during the coupling reaction. A yellow dye image of high colour purity is obtained by the process above. Although fog development occurs on the silver halide grains in the blue-sensitive layer during cyan forming development, the oxidiation product of the developing agent re-acts with the diffusionresisting yellow coupler in the blue-sensitive layer rather than the cyan coupler from the developer. Also, by incorporation of the diffusionresisting yellow coupler in the blue-sensitive layer, development in the yellow-forming developer is accelerated and no underdeveloped silver halide grains are left, which results in a reduction in magenta colour mixing in yellow.

Abstract: 698,650. Fluid-pressure servomotor-control systems. THURBER, A. E. Nov. 2, 1951 [Nov. 8, 1950], No. 25645/51. Class 135 [Also in Group XXX] A hydraulic lift has a hand lever 77 for operating main control solenoid valves 80u, 80d, and automatic floor levelling solenoid valves 20, 24 which are rendered inoperative when the lever 77 is out of its neutral position. Solenoids 109u-111u and 109d-111d may be selectively energized by movement of lever 77 into engagement with any of contacts 126, 128, 131, 136, 138, 141 to control the speed and direction of movement of the car 12; the initial movement of the lever serving to operate a relay 76 through either contact 120 or 121, so energizing a torque motor 72 which in turn rocks levers 33, 34 on the car out of alignment with fixed cams 31, 32 so immobilizing the floor levelling mechanism. When the lever 77 is returned to neutral levers 33, 34 return to an operative position in which when respectively engaged by over and under level cams 31, 32, they effect operation of switch arms 45, 47 so respectively energizing floor levelling solenoid valves 24, 20. As shown in Fig. 7 each valve 80 comprises a spring loaded piston 95 slidable in a cylinder 96 and carrying a valve member 90 which co-operates with a seat 86. Ports 102, 103, 104 are adapted to be interconnected with ports 106, 107, 108 when solenoid valves 109, 110, 111, respectively associated therewith, are energized. Thus, on actuation of one or more. of these valves, fluid, which flows to the space above piston 95 through an adjustably restricted conduit 98 and a' valve 101, is allowed to flow through the interconnected ports to the space beneath the valve member 90. The resulting drop in pressure above piston 95 then causes the piston to rise to a level at which the flow through the ports is rendered equal to the flow through conduit 98 and valve 101, so allowing fluid to flow from chamber 81 to .chamber 82 to effect raising of the car. On deenergizing the valve or valves 109-111 by returning the lever 77 to neutral this flow is slowly throttled, the car is gradually retarded and the levelling mechanism brings it to rest adjacent the selected floor.

Title: Process for the production of gas from heavy hydrocarbon oils
IPC: C10G11/04
Filed: 1929-08-24
Abstract: 338,904. Ramage, A. S. Aug. 24, 1929. Oil gas.-Normally liquid paraffins, e.g. heavy mineral oils, are passed with 1-2 per cent of steam over ferric oxide at 900-1000‹ F., and the gases so formed (principally olefines) are passed with increasing quantities, e.g. 10-40 per cent, of steam over finely-divided iron at increasing temperature, e.g. 1150-1500‹ F., forming combustible gas chiefly hydrogen, carbon monoxide, methane, some aromatic hydrocarbon, and ethylene. The furnace A heated bv an oil burner 15 contains a series 3 - - 6 of tubes with valved conduits 8, 9, 10 for oil vapour, steam and air leading to the inlet header of tubes 6. The oil passes , through tubes 5, 6 containing ferric oxide and tubes 3, 4 containing iron. Steam is added from branch pipes 12, 13. The incoming oil is sprayed at 19 into a chamber D through which. the hot gases pass, and is delivered through an oil preheater 16 to a pipe still B. The vapours so formed pass to an expansion chamber C, where heavy vapours condense and are burnt at 15 in the furnace A, while the lighter vapours pass to the oil-supply pipe 8. The gases formed pass through the chamber B, are cooled in a reflux condenser E to about 450‹ F., and liquid is passed back for re-treatment. Motor fuel in the gas is separated in a further cooler F, permanent gas, passing on. When the ferric oxide is reduced, e.g. after 4 hours, the oil supply is closed and the tubes purged with steam, air being admitted until ferric oxide is re-formed. Specifications 174,574, [Class 32, Distilling &c.], and 338,905 are referred to.

Abstract: 389,152. Wrapping-machines. ROSE, A. G. and ROSE BROS. (GAINSBOROUGH), Ltd., Albion Works, Gainsborough, Lincolnshire. Sept. 16, 1931, No. 25905. [Class 94 (i).] Relates to wrapping-machines of the type having a vertically acting plunger for lifting each of a succession of articles, together with a wrapper, into the folding mechanism. The machine is adapted for dealing with sliced loaves, and means are provided for preventing separation of the slices. According to the invention, the first end folders are moved upwardly out of the path of the second end folders, prior to the folding stroke of the latter. The articles 10 are fed by a band 11 on to a lifting plunger 12, a fixed bracket 13 defining the position. The plunger rises and carries the article, together with a wrapper 14 on the supports 15, 16, between folders 35, 36, a wrapper-retaining device 54 preventing displacement. The folder 35 is pivoted at 37 to a ram 38 and the folder 36 is pivoted at 46 to a bell crank 47, itself pivoted at 48 to a lever 49. Except when engaged by an article, the folders assume the position shown in Fig. 1, lugs 35a, 38a, 36a, 47a limiting the downward movement. The device 54 is pivoted to the lower end of a slide 56 in guides 57. A lug 59 and arm 73 limit downward movement, and the weight of the slide 56 is sufficient to prevent displacement of the wrapper. During the ascent of the article, the sides of the wrapper are folded down by the folders 35, 36, and end supporting plates 74, rising with the plunger 12, hold the constituent slices of the loaf together. End-folders 60, 61, Figs. 1 and 7, with interengaging gears, form the first end-folds. The folders are pivoted at 62, 63 on a frame 64, and are held apart against the action of a spring 128a by links 117, 123, 121, so as to allow room for the plates 74 ; they are then released to fold the wrapper against the ends of the loaf, and the frame 64 rises, carrying the folders and the device 54 with it. The plunger 12 is lowered, leaving the loaf held by the folders 35, 36, and members 33, 34 are moved horizontally to fold the depending portions of the wrapper on the bottom surface of the loaf. The rear end-flaps are folded in by folders 102, pivoted at 104 to a slide 45 and urged inwards by a spring 131. The ram 38, carrying the folder 35, now moves forward and thrusts the loaf to the left, Fig. 1, at the same time the folder 36 is moved backwards and upwards out of the path of the article by the action of the bell crank 47 and lever 49. A resiliently mounted folder 135a turns in the remaining end flap and the final bottom lugs are turned up by a member 137.
