Title: Improvements in or relating to apparatus for processing photographic films
IPC: G03D3/13
Filed: 1946-01-17
Abstract: 626,637. Coating-apparatus. DIEBOLD, Inc. Jan. 17, 1946, Nos. 1611, 1612 and 1613. Convention dates, Jan. 18, 1945, March 7, 1945, and Aug. 30, 1945. [Class 140] [Also in Group XX] A device through which photographic film may be fed to receive various processing fluids comprises several upright U-shaped film guide members with an inverted U - shaped guide portion above and between adjacent legs of successive upright U-shaped guides and cooperating drive and free rollers positioned so that a pair of such rollers engage the film at the upper end of each leg of the successive upright U-shaped members. In one form, the device consists of three tanks 31, 47, 48, Fig. 1, joined by a cross-bar 49, the tank 31 may contain a developer-fixer, the tank 47 a stopper and the tank 48 may contain water, which may be continuously circulated therethrough. Mounted as at 33, 73 in the tank 31 are conduits 29, 42 which, together with a member 38, form a U- shaped guide member ; each conduit is formed from V-shaped bars as shown in Fig. 2, through which the film 22 having a leader strip 23 is guided, the film passing down conduit 29 under a free roller 36 and then up conduit 42. Similar conduits are mounted in each of the tanks 47, 48, the openings between the V-shaped bars of each conduit allowing processing of the film by the fluids in the respective tanks. The film is drawn into conduit 29 by a roller 27 co-operating with a free roller 25 spaced therefrom a distance greater than the film thickness but less than the thickness of the leader. As the film passes into each succeeding tank it is engaged by drive rollers co-operating with a free roller therebetween, guide members as at 74 being mounted over such free rollers. The film on leaving the tank 48 is engaged by co-operating drive and free rollers 69, 70 which are spaced apart a distance less than the film thickness so that the film itself is driven and excess fluid is squeezed therefrom before it passes to a dryer (not shown). In other embodiments described, the U-shaped guide members are in the form of closed tubes and the fluids are pumped from separate tanks to pass up each leg of each tube and then through aligned slots near the upper end of each leg back to the respective tank, the drive rollers being driven through gear reduction mechanism and worm gears by an electric motor which is energized by the same source as electric motors, which drive the pumps. The whole equipment is mounted on a single support and means, i.e. springs, may be provided to allow of constant pressure between the drive and free rollers. In one embodiment, the free rollers over which the inverted U-shaped guide members are mounted are movable vertically against spring pressure so that if one film loop becomes shortened the free roller descends so that the drive rollers cannot drive the film until the correct loop length is obtained, whereupon the free roller returns to its normal position under the spring action.

Abstract: 1,100,564. Arc extinguishing in switches; gas blast switches. E. LANGE. 15 Jan., 1965 [22 Jan., 1964], No. 1793/65. Heading H1N. In an electric circuitbreaker the electrodes 8, 7, 9 are made of a material comprising a physical combination of metallic and gas-evolving non-metallic substances. The non- metallio substances are such as to evolve electronegative gases when subjected to the heat of the arc. For instance P.T.F.E. and sulphur may produce sulphur fluorides. Other suitable non-metallic substances are the silicofluorides of barium, calcium, sodium, ammonia, copper or lead. The metallic substances may be resistant to the arc, for example molybdenum or tungsten. The physical combination may be achieved by sintering powder mixtures; by melting and casting the substances together; or by superimposing them in layers. The arc chamber 1 may be sealed and charged with the electronegative gas before operation; the chamber comprises several compartments 4, 5 (13, 14, 22, Fig. 2, not shown) and flow of the gas from one to another extinguishes the arc.

Title: Improvements in cameras for colour photography
IPC: G02B27/14
Filed: 1930-01-18
Abstract: 349,107. Colour photography. HILGER, Ltd., A., and DOWELL, J. H., 24, Rochester Place, Camden Road, London. Jan. 18, 1930, No. 1821. [Class 97 (i).] The combination of prisms, in an optical system for colour photography, by which the incident beam is divided so that several images of the object are formed is constructed of glasses of more than one refractive index the prisms being so dimensioned and located that the total lateral shift of rays of the same obliquity of initial incidence is the same for each of the selected colours. This ensures that the images for near objects are the same for different colours as well as the images for distant objects. The prisms are dimensioned so that the optical paths through the system are the same for each colour. The mathematical basis for the necessary calculations are set out at length in the Specification. In the form of optical system shown in Fig. 1, the surface J between the prisms A, B is silvered to reflect and transmit the desired proportions of light received for reflection from the surfaces of the prisms C, D to enable images to be formed by the lenses E, F on the film f. The path of the rays is shown in Fig. 3 in which the distance L1 is the total length of the paths in the prisms A, B and the distances L2, L3 are the lengths of the paths in the prisms C, D for the two colours. The refractive index for each of the prisms C, D is chosen so that the points N, P of emergence of the rays are in the same horizontal plane, so that no lateral shift exists for rays of the same initial obliquity. An example is also given embodying the application of the principle to a three-colour system.

IPC: B25B23/10
Filed: 1919-01-27
Abstract: 122,849. Lundmark, J. Jan. 27, 1919. Screwdrivers.-In screwdrivers of the kind provided with a gripping device for holding the screw while it is being driven, the gripping device comprises a pair of jaws flexibly connected together and slidable on the driver and controlled by a member also slidable on the driver and moved in one direction manually to open the jaws to engage the screw, and in the other direction by a spring to close the jaws to grip the screw. The jaws may be constructed to grip the screw by its head and also at one or more points along its length. In one form, Fig. 2, the jaws 8 are connected by a spring 11 tending to open them, and are provided with slots 7 for the passage of pins 5 and 9 connecting the arms of the controlling member 4. The pins 5, 9 also pass through a slot 6 in the driver 1, and the pin 5 is provided with guide flanges or projections 14. A spring 3 normally presses the member 4 and, with it, the jaws 8 towards the handle of the tool, so that the point of the driver projects beyond the jaws, and the tool may then be used as an ordinary screwdriver. In operation, the member 4 is pushed forward against the spring 3, the pin 5 engaging the outer end of the slots 7 and pushing forward the jaws 8 which open out by the action of the spring 11. The screw is then inserted between the jaws 8 and the member 4 released to allow it to be retracted by the spring 3 and by the engagement of the pin 9 with the inner ends of the slots 7 to withdraw and close the jaws 8 to grip the screw 12 and hold it firmly in engagement with the point of the driver, as shown. When the screw is driven in so far that the jaws 8 engage the work, the jaws are automatically pressed apart to release the screw and are fully retracted by the spring 3. In a modification, Fig. 5, the jaws are provided with two or more sets of notches 15, 16 to hold the shank of the screw 12 as well as its head, the jaws on meeting the surface of the work releasing the screw head from the first set of notches 16 and re-engaging it with the next set 15, finally releasing the screw as in the construction shown in Fig. 2. The jaws 8, Fig. 5, are provided with inclined surfaces 17 adapted to be engaged by the arms of the member 4 to close the jaws against the action of the spring 11, and this spring is .shaped to engage frictionally with the sides of the driver 1 so that the jaws do not move forward with the member 4 until the pin 5 engages the end of the slots 7, thereby ensuring the opening of the jaws by the spring 11 to receive the screw. Thumb projections 21 are provided on the member 4 for actuating it.

Abstract: 418,948. Clockwork-actuated valves. BERGER, H., 18, Oberdorfstrasse, Essen- West, Rhineland, Germany. Jan. 22, 1934, No. 2148. [Class 135.] A clock for controlling the operation of an electric switch or a cock in a gas or liquid conduit, comprises a main time indicating clockwork which releases at predetermined times, and two auxiliary spring driven trains which serve to open and close the switch or cock respectively. Means are also provided to open the switch or close the cock if the clockwork mainspring breaks or becomes unduly unwound. The apparatus is described as controlling a cock 49, Figs. 2, 4, rigid with a two-armed lever 50, 51 shown for both the open (full lines) and closed (dotted lines) positions of the cock. The main clockwork (not shown) drives the hour and minute hands 1, 2, Fig. 1, and through a pinion 37, Fig. 2, rotates wheels 35, 36 freely mounted on shafts 38 which carry the hands 6, 7 indicating on scales 4, 5, the times at which the cock is to be opened and closed respectively. The hands 6, 7 are set through bevel gearing by rotating knobs 8, 9. The auxiliary train springs are anchored at 18, Fig. 3, to the frame plate 20 and their inner ends are connected to the spindles 12, 13 respectively, through which the springs are wound by rotating levers 10, 11, Fig. 1, in the directions indicated by the arrows 25, 26 respectively. These springs when released, drive wheels 16, 17, Fig. 3, geared through their associated trains to blade wheels 21, 22, normally locked by detent springs 29, 30 respectively. The detent springs are carried by blade springs 33, 34, Figs. 2, 4, stressed against the hubs of the wheels 35, 36 which have surface cams 39, Fig. 4, coacting with radial pins on the shafts 38 and in known manner move axially under the action of the blade springs 33, 34 at the times indicated by the hands 6, 7 to release the respective trains. Rigid with the spindle 13 is a lever 42 to which is pivotally sprung a lever 45, 45<a>, and when the spindle 13 returns to the dotted positions, Fig. 1, during the running of the corresponding train, the lever arm 45 engages behind a pin 51<a> on arm 51, rocks the cock 49 to the closed position, and comes to rest against a buffer spring 56. A corresponding lever system 41, 44, 44<a> associated with spindle 12 coacts with a pin 50<a> on the arm 50 to open the cock. Should the mainspring of the time indicating clockwork break or become unduly distended, the outer windings thereof abut against and rock the end 62<a> of a lever 62, Fig. 5, pivoted at 63, whereupon through a lever system 61, 59, 58, 57 the cock 49 is closed. Alternatively, the movement of the lever 62 may be adapted to release the train associated with the spindle 13 which is thereby rotated to close the cock.
