Title: Improvements in or relating to processing apparatus for photographic light-sensitivepaper
IPC: G03D5/06
Filed: 1947-05-23
Abstract: 632,823. Photographic processing apparatus. KODAK, Ltd. May 23, 1947, No. 13967. Convention date, May 25, 1946. [Class 98 (ii)] Apparatus for processing photographic paper sheets comprises a rotatable drum having a moisture-carrying covering which dips into a tank for a processing solution, a wringer roller in frictional driving engagement with the drum covering to squeeze a meniscus of solution from the covering across the full width thereof, guide means located adjacent the wringer roller for introducing a sheet through the meniscus of solution and between the drum and wringer roller so that both surfaces of the sheet are evenly moistened and the sheet is smoothed against the covering to be conveyed thereby, and a scraper bar engaging the drum covering at a position spaced from said roller to strip the processed sheet from the drum. As shown, two processing units are connected in tandem, one for developing and the other for fixing, the parts being mounted between side plates 1. Drums 8, 20 dipping into a developer tank 10 and a fixer tank 22 respectively and each covered with muslin which is wound at least twice round the drum in a direction opposite to that of rotation, the damp muslin adhering to the drum without using fastenings, are driven at the same speed by a chain 37 engaging a sprocket 36 on the shaft 5 of the drum 20 and a chain 35 which drives sprockets 33, 34 on the drum shafts 3, 5. Wringer rollers 6, 24 on spindles 2, 4 are frictionally driven by the drums 8, 20 and each squeezes out from the drum covering a meniscus of liquid B extending across the width of the drum. A paper print to be processed is pushed up the guideway A until it is drawn forward by engagement with the drum and roller. The print is wetted on both sides, thus reducing its tendency to curl, by passing through the meniscus B and is flattened on to the drum 8 by the roller 6 where it remains until picked off by a scraper bar 15, pin-and-slot secured to a support 18, whose edge 19 is thinner than the print. It then is picked up by the fixer drum 20 and passes beneath the wringer roller 24 which seats it on the drum where it remains till it is peeled off by a scraper bar 29, when it falls into a tray 26 across which a drying blast of warm air is directed. To ensure proper feeding of the developed paper to the fixer drum, spring guiding fingers 51 carried by a rod 50 are provided. For ease of access the liquid tanks 10, 22 are mounted on a frame 12 hinged at 47, 42 by links 45 and bell-crank levers 40 carried on the sides 1 at 46, 41, one lever 40 having a snap latch 43 which when released allows the frame to move down to lie between the dotted line position of the levers 40 and links 45.

Abstract: 1,218,877. Filters. SHELLER - GLOBE CORP. 18 March, 1969 [22 April, 1968], No. 14006/69. Heading D1R. A randomly dispersed mass of fibres is made into a filter by depositing a predetermined mass of, e.g. cotton fibres onto a conveyor 10 which transfers them to a belt 11 where they are compressed into a generally rectangular mat by a pressure belt 12 as they are carried towards a forming cylinder 13. The mat passes through a slot 14 in the cylinder 13 onto a rotating mandrel 15 to form a cylindrical mass of fibres. A piston 16 is then moved axially by actuation of a cylinder 55 to strip the material from the mandrel 15 into the shell S which has been clamped against a wall 47 by actuation of cylinder 59. The slide 57 and supporting plate 56 for the shell S are then retracted and an ejector 17 actuated simultaneously to eject the loaded shell onto a chute 18 (Fig. 2).

Title: Improvements relating to photographic cameras
IPC: G03B13/20
Filed: 1937-05-21
Abstract: 495,805. Photographic cameras with telemeters. TOMLINSON, A. V. (Goodchild, B. F.) May 21, 1937, Nos. 14222/37 and 12375/38. [Class 98 (i)] A photographic camera comprises two telemeters the setting members of which are each coupled by suitable mechanism, both to the focusing device and to the diaphragm setting device of the camera, in such a manner that these setting members are actuated by equal amounts in the same direction, when the focusing device of the camera is adjusted without altering the diaphragm setting device, and by equal amounts in opposite directions, when the diaphragm setting device is adjusted while maintaining the adjustment of the focusing device unaltered. In this way the depth of focus for any setting of the diaphragm and focusing setting devices is determined. In the form shown in Fig. 1, the lens 2 is carried in a mount 3 and has a diaphragm setting lever 6 on the end of which are pivoted three satellite pinions 5, 8, 7 connected together. These pinions engage respectively the toothed ring 4 integral with the lens mount and the rings 9 and 10 loosely mounted thereon. The latter rings operate the movable elements 11 and 13 of two telemeters 11, 12, 13, 14 through gearing 15, 16. The Specification gives details of the required relationships of the various gear diameters. A lost motion device may be provided to allow the lens to be focused beyond the hyperfocal distance without the " far limit " telemeter being moved beyond the infinity position. Another such device may permit the diaphragm setting member to be moved beyond the position corresponding to the maximum aperture of the lens in use. Interchangeable units may be provided, each including as well as the lens the telemeter members 11 and 12, and the necessary gearing. In the form shown in Fig. 2, two tubes 18 and 19 participate in the focusing movement of the lens mount and this movement is transmitted by levers 24, 25, 32, 33 to the telemeter members 11 and 12. Oppositely inclined slots 20 and 21, in the respective tubes, are engaged by a pin 22 on the diaphragm ring 23. Adjustment of the ring relative to the lens mount therefore operates the telemeters in opposite directions. The ends of the tubes 18 and 19 engaging the levers 24, 25 may have cam surfaces.

Title: Photographic camera
IPC: G03B9/58
Filed: 1951-06-19
Abstract: 693,867. Photographic cameras. KOCH, C. June 19, 1951 [June 21, 1950], No. 14537/51. Class 98 (i). A photographic camera of the dark slide type is provided with a shutter which is maintained in the open position when the camera does not have a slide therein, a device for opening and closing the shutter, means connected with the opening and closing device and operable to close the shutter by a slide as it is fitted into the camera, and a cocking and releasing device which is connected to the shutter independently of the opening and closing device. As shown, a pivoted blade shutter 1 of the everset type is operated by an antinous cable 15 to effect an exposure. On closing the dark slide 14 and removing it from the camera back, a pivoted lever 11 fixed to the outer sleeve of a Bowden cable 4 rocks anticlockwise so that the inner member of the cable being fixed to projections 6, 10 on the lens board and camera back respectively, a pivoted lever 2 secured to the other end of the outer sleeve rocks clockwise to open the shutter, thereby permitting focusing on a ground glass screen in the camera back. On inserting another dark slide into the camera back, the shutter is closed so that the cover of the dark slide may be removed ready for an exposure without danger of accidental fogging. In an alternative construction, the slide may be engaged by an arm fixed on a telescopic shaft, including an articulated joint to facilitate focusing, to which is secured at the front end an arm adapted to open the shutter. Instead of a mechanical control of the shutter, the insertion of the dark slide may cause the lever 11 to close an electric circuit to a solenoid which closes the shutter.
