Title: Improvements in or relating to photographic shutters
IPC: G03B9/10
Filed: 1961-03-14
Abstract: 930,915. Photographic shutters. KODAK Ltd. March 14, 1961 [March 17, 1960], No. 9365/61. Class 98 (1). A photographic shutter comprises within a casing a single blade provided with an exposure slot, means for mounting the blade for movement from a rest position to a cocked position over one path, during which movement the blade acts as a cover blind for an exposure aperture in a wall of the casing, and for movement over a different path from the cocked position to an intermediate position, during which movement the exposure slot in the blade moves across the exposure aperture to make an exposure, means for moving the blade from its rest position to its cocked position and a drive spring for moving the blade from its cocked position to the intermediate position for effecting an exposure. As shown, the single shutter blade 15 is formed integrally with a drive spring 16, a return spring 17 and a guide member 18 slidable in a groove 26. On depression of a trigger member 29, the blade 15 moves from its rest position (Fig. 3) through a cocked position (Fig. 4) in which spring 16 is fully tensioned and tip 46 of a cut-out 41 is on the point of slipping off a post 40 to an intermediate position (Fig. 6) in which the tension in spring 16 is fully relieved, an exposure having been made through an aperture 12 as the blade is driven from its cocked to its intermediate position, an exposure slot 48 being provided in the blade for this purpose. Return of the blade to its rest position is effected under loading of spring 17, a ramp 42 being provided to enable the blade to pass over post 40. To prevent rebound of the blade 15 after an exposure a slot 38 is provided into which a lug 35 on the blade 15 drops after having ridden up an inclined dampening ramp 36, the engagement between lug 35 and wall 34 also providing means for ensuring the proper return of the blade to its rest position. A weak spring 56 is provided for engagement with an inertia member 22 on spring 16 to reduce the impact of this member on the shutter casing wall 10. The engagement between ramp 42 and tip 46 shortly before exposure may be used to complete a flash circuit. In a modification (Fig. 7), the blade 15 is provided with two exposure slots 48<SP>1</SP> and 70 and post 40<SP>1</SP> is mounted on a member having two positions of adjustment so as to provide for two exposure times. In a further modification (Fig. 9), a member 80 is pivotally mounted on the blade 15 so as to provide an adjustable exposure slot whereby a range of exposure times may be obtained, sufficient friction being provided between members 80 and 15 to maintain them in fixed relative position during an exposure.

Title: Improvements in fibrated coatings and in processes for applying such coatings to a surface
IPC: E04D7/00
Filed: 1961-03-14
Abstract: A method of forming a protective coating on a roof or other surface exposed to the weather comprises blowing a stream of short lengths of inorganic fibres from a spray nozzle towards said surface while simultaneously spraying an aqueous emulsion of bitumen from at least one further spray nozzle toward the surface, the spray nozzles being convergent so that the fibres become coated with emulsion just before they strike the surface, the blowing of the fibres being effected with sufficient impelling force to deposit the fibres on the surface in a jackstraw pattern disposed substantially parallel to the plane of the surface, the emulsion being of the type which forms a stable film upon drying thereof, and continuing blowing the fibres and simultaneous spraying of emulsion until there has deposited on the surface a layer of fibres and emulsion which upon drying of the aqueous content of said layer will form a monolithic coating of a thickness ranging from 25 mils to about 1 inch.  The emulsion may be one in which the sole suspending agent is a clay or one in which a soap type emulsifying agent and a clay filler are used. The preferred inorganic fibres are strands of fibre glass preferably 3/4 inch long. The coating may be applied to roofs of cement, wood, metal, poured gypsum, or vermiculite cement; or to a layer of roofing felt which is first attached to the roof.  The emulsion may contain powdered aluminium as a pigment.  Coloured coatings or roofing granules may be applied to the coating.  The coating may also be applied to walls, earthen or concrete canals and the inside and outside of tanks.

Title: Improvements in the manufacture or treatment of artificial filaments, yarns, films and similar materials
IPC: D01F2/28
Filed: 1934-03-28
Abstract: Artificial filaments, yarns, films, and the like of organic derivatives of cellulose, are subjected to stretching operations while they are softened under the influence of a medium containing an organic softening agent maintained at super-atmospheric pressure. Suitable softening agents mentioned are acetone, methyl ethyl ketone, ethers including cyclic ethers, ether-esters and esters of glycols, e.g. methylene ethylene ether, dioxane, mono- and di-methyl ethers of ethylene or propylene glycol, ethyl ethers of ethylene and propylene glycols, glycol monoacetate and ethyl glycol monoacetate; also formaldehyde, acetaldehyde, methylene chloride, ethylene chloride, dichlorethylene, mono-, di-, and tri-acetins, acetic acid, methyl, ethyl, propyl and isopropyl alcohols, benzene, toluene, xylene, and isopropyl and higher ethers.  Some of the agents may be employed diluted with steam or water.  For example, there may be used a 10--5 or even 3 per cent aqueous solution of acetone or dioxane at 70 to 120 DEG  C. under super-atmospheric pressure.  Preferably, the conditions of pressure and temperature existing during the application of the softening medium are the same as those during the stretching operation.  The stretching operation, which may produce a permanent elongation of 30 to 1000 per cent or more, may be carried out on yarns proceeding from a spinning cell, on yarns in hank form, or on yarns in course of travel, e.g. during winding from one bobbin to another.  A number of threads may be stretched in parallel alignment during the course of their travel from one point to another.  In an example, cellulose acetate yarn is passed through a dilute aqueous solution of acetone contained in a vessel and maintained under a pressure of 50 to 60 lbs. per square inch above atmospheric pressure.  In a second example, an aqueous solution of methanol is employed.  In another example, cellulose acetate yarn is stretched during its travel through a vessel containing a mixture of acetone and steam at 118 DEG  C.  In a fourth and similar example, a mixture of methyl alcohol and steam at 110 DEG  C. is employed.  The products may be subjected to any after-treatment such as shrinkage, delustring, and saponification. According to the Provisional Specification, the process may be applied also to the treatment of yarns of regenerated cellulose obtained from viscose, cuprammonium, and nitrocellulose artificial silks, and as suitable softening agents specifies sulphuric acid, hydrochloric acid, phosphoric acid, thiocyanates, Schweitzer's reagent, and zinc chloride. Specifications 177,868, 179,234, 207,562, 277,089, 316,521, 318,468, [all in Class 2 (ii)], 340,324, 340,325, 340,436, 340,437, 343,062, 380,504, 380,505, 389,823, 402,104, 402,105, 402,106, 403,106, 424,683, 424,752, 424,830, and 424,879, [all in Group IX], are referred to.
