Title: Improvements in or relating to photographic cameras
IPC: G03B17/42
Filed: 1957-12-02
Abstract: 842,036. Photographic cameras. JLOCA CAMERA HANDELGESELLSCHAFT. Dec. 2, 1957 [Dec. 14, 1956], No. 37498/57. Class 98(1) In a roll-film camera, the film is wound by an electric motor which has a cylindrical housing serving on the take-up spool. As shown, the electric motor is supported by mounting the ends of its rotor shaft 8 in fixed bearings. The shaft 8 drives the motor housing 7 through pinion 9 meshing with gear wheel 12 and pinion 13, fast with gear wheel 12, and meshing with gear wheel 10 on housing 7. The exposed film is wound on housing 7 and the motor is energized from a battery through slip rings. As the film is wound on housing 7 it rotates a sprocket 39 engaging the film perforations. Sprocket 39 carries a conducting plate 41 of silver or platinum/iridium which has notches 42 filled with insulating material. Spring blades 43, 44 of the same material lie in sliding contact with the plate 41 and are connected in series with the motor. The initial displacement of the film to establish electrical connection between blades 43 and 44 through plate 41, which subsequently allows the motor to complete the film changing operation by a half-turn of sprocket 39, is effected by a momentary depression of spring blade 45 on to plate 41 by cam 46 connected to the shutter mechanism, thus momentarily energizing the motor through an alternative path 47. On meshing gear wheels 58 and 63 by withdrawing a re-wind knob to its first click and on reversing the motor by switch 18 (which also short circuits blades 43, 44), the film is re-wound into a cassette. Gear wheel 63 is driven by connecting rods 65, 66 from wheel 64 meshing with wheel 10 and variation of the diameter of the coil in the cassette is allowed for by a slipping of the frictional coupling, between wheel 58 and a spool driving member. The re-wind knob can be withdrawn to a second click stop to enable the cassette to be removed. At the same time as winding on the film, the motor also sets a lens shutter through mutilated gear wheel 21 meshing with pinion 13. Connecting rod 25 imparts reciprocating motion to rack 27 which thus drives pinion 30 in one direction to set shutter 77 and in the other is lost-motion with respect to the shutter j setting shaft 33. Two, 31 and 34, of collinian shafts 31, 34 and 33 carry sleeves 32 and 37 respectively. Pins 35 and 38 on the ends of shafts 34 and 33, respectively, ride in the slots in the sleeves and permit focusing movement of the lens mount and the lost-motion return of pinion 30, respectively. As the exposure is made shaft 33 rotates to follow sleeve 37 and, when pin 38 reaches the driving end of slot 36, it imparts a slight rotation to pinion 30 and cam 46. Thus blade 45 is brought into contact with plate 41 to energize the motor and wheel 21 is rotated into mesh with pinion 13. A flash-lamp carried on a shoe may be fired by the battery through a terminal. Alternatively, the motor may be driven by a battery outside the camera casing such as the battery of a separate flash-lamp.

Title: Improvements in or relating to central buffer couplings of railway vehicles
IPC: B61G7/10

Abstract: 1,018,501. Central buffer couplings for railway vehicles. J. VIELMETTER. Oct. 4, 1962 [Oct. 7, 1961], No. 37641/62. Heading B7T. A rod 1 which carries at its left-hand end a central buffer coupling and is connected at its other end to a universal joint and a draw and buffer gear, is supported and centralized from below by a compression spring 13 confined between plates 5, 11, and by separately adjustable struts 29, 31 connected to the plate 11 and bearing on seats 39 fixed to the vehicle frame 37. The plate 5, which is pivoted at 7 to the rod 1, has fixed thereto a tube 27 which provides a limit stop for a plate 19 (see also Fig. 3, not shown), displaceably mounted on a tube 9 also fixed to the plate 5. Fixed to the plate 11 is a spacing tube 15 which carries an annular stop 17, and a further spring 21 acts between the plate 19 and a ring 25 which may be axially adjusted by screws 23. In operation a downward force on the coupler compresses the springs 13, 21 which exert a restoring force, but with a horizontal sideways deflection of the coupler the device tilts on one of the struts 29, 31 about one of the seatings 39, the other strut being lifted from its seating. As the whole device is thereby pivotally lifted a little on one leg, when the displacing force is removed the weight of the coupler will act as a restoring force to centralize the gear. By altering the length of one or both of the struts the vertical and horizontal mean position of the coupling can be adjusted. When the coupler head is lifted the tube 27 is lifted from the plate 19 and the rod 1 is supported only by the spring 13. The compression of the spring 21 can be varied by adjusting screws 23. The common axis of the plates 5 and 11 may, however, be arranged to lie in a vertical plane.

Apparatus for measuring rate of flow or delivering predetermined quantities of fluent material comprises a pair or series of containers, a torque motor restraining movement of a container from a filling position and means controlling the torque motor in accordance with the amount of material in the container. Fluent material from a nozzle 34 fills a bucket 33, tending to rotate it about a shaft 31. The shaft carries a bifurcated vane 13,14 which cooperates with two photo-cells 11, 12 connected to a differential amplifier 16 to produce a control signal. The control signal, which has an unstable zero position between two stable zeros, is applied to the torque motor 22, 23 in a sense to reduce the movement of the buckets 32, 33. When the output of the difference amplifier 16 reaches a predetermined level, a resistance is switched into circuit with the torque motor to reduce the control signal. This has the effect of switching the apparatus from one stable state, through the unstable state to the other stable state, thus emptying bucket 33 and bringing bucket 32 into the filling position. A counter recording the switching may indicate rate of or total flow.

Abstract: 1,075,304. Endless conveyers. SCHWEIZERISCHE INDUSTRIE GESELLSCHAFT. Sept. 18, 1964 [March 2, 1964], No. 38174/64. Heading B8A. In a device for conveying and aligning flat articles, e.g. waffles or biscuits 2, the articles are placed vertically next to one another, but not precisely aligned, in U-shaped containers 1 which are moved by a conveyer chain (not shown) step-by-step in the direction of arrow (A, Fig. 2, not shown). Push-bars 4 secured to two endless chains 5 push individual groups of articles 2 along a track 3 and an endless chain 7 having pushers 12 transfers groups of the articles from the containers 1 on to the track 3 in the zone of operation of the push-bars 4. The pushers 12 are carried by levers 10 which are pivoted to the chain 7 at points 11, and each lever 10 is connected by a link 14 to a further point 16 on the chain 7. The speed of this chain is greater than that of the chains 5. As a pusher 12 begins to push a group of the articles on to the track 3, a push-bar 4 moves upwardly through a slot 15 in the track and takes over the pushing of the articles. Since the pusher 12 moves quicker than the push-bar 4, the articles are moved towards the preceding bar 4 and become aligned by the latter. Due to tilting of the lever 10 as the pivot point 11 moves from the lower run of the chain 7 around a pulley 8, the absolute conveyance speed of the pusher 12 is retarded such that the articles are not crushed between the pusher 12 and the push-bar 4. The pusher 12 is then raised from the articles and the bar 4, which is following, takes over the pushing.
