Filed: 1926-04-20
Abstract: 251,614. Kodak, Ltd., (Assignees of Underwood, E. E.). May 4, 1925, [Convention date]. Kinematograph apparatus .-Intermittentfeed mechanism is so constructed that the film feeding members may be moved into an inoperative position to facilitate threading of the film. As shown, the film is fed by chains 44 on a member 41 which is pivoted on a member 37 and is pressed towards the film by a spring 43. The member 37 is pivoted on a rotary driving disc 35 and is connected by a link 40 to a fixed rod 42. A lever 50, mounted on a pivot 49, normally occupies the position shown in broken lines in Fig. 1, and serves as an edge guide for the film in the gate, but it is capable of being turned into the position shown in continuous lines so that a hook 53 at its end engages the member 41 and turns it away from the film. Operation of the mechanism while the lever is in the latter position causes the hook 53 to engage in a notch 48 in the member 41 and lock the mechanism. The gate comprises a curved member 24 removably secured to a partition 12 in the apparatus by a base plate 25 having holes engaging over pins 22, 23, the pin 23 being notched to accommodate a spring 30 secured to the member 24.

Title: Improvements in processes of photographic reproduction
IPC: G03C11/12
Filed: 1948-04-15
Abstract: 655,275. Photographic processes. KODAK, Ltd. (Eastman Kodak Co., and Yackel, E. C.). April 15, 1948, No. 10546. [Class 98 (ii)] A photographic image is produced in a substantially unhardened layer of a colloidal binder, and a moistened outer thin continuous stratum of the entire layer is transferred to another support, which may be absorbent. The unhardened layer may be a gelatino-silver halide emulsion layer, which is moist or treated with a softening agent, before transference. Alternatively the absorbent support may be heated. The emulsion, carried on a paper, film, or other support, may be exposed by projection or contact printing to obtain a reverse positive, developed, fixed in a non- hardening fixing bath, and washed. While the emulsion layer is still moist, and if desired, after treatment with a gelatin softening agent, a paper, cloth, wood, or similar absorbent support is rolled down on to the emulsion layer and then stripped therefrom carrying a thin continuous stratum of emulsion. In example 1, aqueous solutions of silver nitrate and sodium chloride are simultaneously run into an aqueous gelatin solution while stirring, an aqueous gelatin solution is added, a small quantity of aqueous formaldehyde solution (or alum or a chromium salt) is added, and the emulsion is coated on to a paper support. After exposure, the material is developed in a metol-hydroquinone developer, fixed in an aqueous solution of sodium thiosulphate, sulphite, and bisulphite, washed, and treated with an aqueous solution of urea, formamide, ethylene chlorhydrin, sodium nitrate, or glycerol to soften an outer thin stratum. Paper is rolled down on to the moistened and softened emulsion layer for a short time, and then stripped off, carrying a thin stratum containing the image. The emulsion layer may again be moistened with one of the softening solutions and a second transfer effected on to an absorbent support. In example 2, the support is heated to cause a thin outer stratum of the emulsion layer to melt and transfer to the support. This may be preceded by treatment with a gelatin softening solution, and further prints may be similarly made. The transfer may be effected at any of the stages after exposure, after exposure and development, after exposure, development, and fixing, or after exposure and complete processing (including washing), the remaining necessary steps being effected after transfer. From 10 to 12 prints may be made. The emulsion binder may be gelatin, polyvinyl alcohol, partially hydrolysed cellulose or polyvinyl ester, or a resin such as polyacrylamide. An image may be formed in a colloid layer by imbibition and successive transfers made from the colloid layer, diffusion being prevented by use of a mordant. A silver image may be toned before transfer. Specification 655,274 is referred to.

Title: Improvements in and relating to methods of and apparatus for synchronising and for comparing the speeds of rotating elements
IPC: H01J13/42
Filed: 1930-04-03
Abstract: 352,985. Stroboscopic apparatus. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London.-(Assignees of Aronoff, S. ; 307, Clinton Place, Newark, New Jersey, U.S.A.) April 3, 1930, No. 10547. Convention date, April 3, 1929. [Class 97 (i).] Rotating elements are synchronized and their speeds compared without imposing any external load on the moving elements. Referring to Fig. 1, two rotating elements 1, 2, e.g. of a standard and test watt-hour meter respectively, have their edges formed of alternate surfaces of light-reflecting and light-absorbing materials. Light from a lamp 3 is focused by the lens 5 on the edge of disc 1 and is absorbed or reflected to be focused by the lens 6 on the photo-electric cell 4 to produce periodic electric impulses amplified by, for example, a three electrode vacuum tube amplifier 7 to periodically energize a neon tube 8 from which periodic flashes of light fall on the edge of the disc 2. By utilizing the stroboscopic effect produced and by adjusting the speed of the disc 2, the disc 2 can be synchronized with the disc 1. Fig. 2 shows apparatus for comparing the speed of the armature 13 of the meter 10 with the speed of the armature 14 of a standard meter 12. The disc 15 is driven at a speed proportional to that of the armature 14 through the light source 38, light-reflecting surfaces on the armature 14, photo-electric cells 17, amplifier 39, and synchronous motor 16. A stationary stroboscopic effect is produced from the intermittent light from the lamp 22 reflected from the reflecting surfaces on the armature 13 by adjusting the position on the disc 15 of the friction wheel 18 carrying alternate conducting and insulating segments 23, 24 for intermittently lighting the lamp 22. The wheel 18 is connected to a pointer 20 reading against a scale 21 graduated to read in percentage differences of speeds of the armatures 13, 14, compared with the speed of the armature 14 of the standard meter, or to read in differences of speed expressed in terms of any desired function of the speed of the armature 14 of the standard meter. The meter 10 under test is connected to measure exactly the same load as the standard meter 12 and the test is repeated for different loads.

Title: Apparatus and method for hazardous vapour removal in refuelling of aircraft
IPC: B65H75/44
Filed: 1959-03-31
Abstract: <PICT:0872205/III/1> Air containing fuel vapours, which is displaced from the fuel tanks of aircraft during refuelling, is forced by the pressure of the entering fuel through a conduit leading from the vent of a fuel tank into an enclosed bed of finely divided adsorbent and air free from fuel vapour is discharged therefrom.  A suitable apparatus comprises a carriage (11) supporting at least one absorption chamber (17) having an inlet (28) and an outlet (24) and means to connect said inlet to the fuel tank vent.  The adsorbent material may be regenerated after removal or whilst still in the vessel by passing superheated steam there-through. The numerals refer to the embodiment shown in Fig. 2, wherein two similar adsorbent chambers are provided, in which the beds are of cylindrical form.  An axial outlet duct 26 is provided in each chamber and each bed is supported on a perforated plate 27 whereby the fuel-free air can reach said duct.  The vapour-laden gas passes downwardly through the adsorbent, e.g. of activated carbon and since the absorption is accompanied by emission of heat, the degree of saturation of the bed may be determined by noting the vertical location of a hot zone. When the latter reaches the lower part of the bed a thermosensitive device 71 indicates that the bed is spent.  The inlets of said beds are connected to a valve-controlled manifold so that the gases can be directed to the desired bed.  A rotating spool (Figs. 3 and 4, not shown) (see Group XXVIII) is provided on the base 11 to hold a length of flexible tubing for attachment to the fuel tank vent in such manner that it can be readily unwound for use and automatically rewound when refuelling is complete.
