Patent GB-631180-A (GB)
Title: Improvements in or relating to photographic shutters
IPC: G03B9/22
Filed: 1946-08-30
Abstract: 631,180. Photographic shutters. KODAK, Ltd. Aug. 30, 1946, No. 26172. Convention date. Sept. 1, 1945. [Class 98 (i)] In a photographic shutter of the setting type in which a single manually operable member is mounted to move in two opposite directions through a fixed arcuate path in the shutter casing, movement of said member in one direction tensioning a shutter blade master member which is maintained in its set position by a pivoted latch, and movement in the opposite direction releasing the latch so that the master member actuates the shutter blades, the master member is pivotally mounted at one end of said path of movement and the pivoted latch includes an arm extending across the other end of said path and carries a pair of spaced pins which alternately engage a radial arm on the blade ring, the first pin moving the arm to cause the shutter blades to open and the other pin subsequently moving the arm and hence the blades in the opposite direction to close the shutter aperture. As shown, the shutter which has an upstanding flange 2 on its casing 1, includes a mechanism plate M apertured at 3 and cut away at 4 to expose an arcuate grooved track 5 in the base plate 9 for guiding the operating member or slide 6 which is movable by a handle 7 extending through a slot 8 in the flange 2. To set the master member 18 the slide 6 is moved clockwise so that a pin 32 on it engages an edge 31 of the master member and rotates it on its pivot 19 against a spring 23 until the tip 16 of a latch 14 pivoted at 15 on the plate M and urged anticlockwise by a spring 35 engages a latch element 17 on the master member, the bevelled edge 27 of a pin 26 on the master member sliding beneath the blade ring arm 38. On releasing the handle 7 the slide is returned to its rest position by a spring 10. Movement of the slide anticlockwise causes a pin 11 on it to trip the arm 13 of the latch 14 so freeing the master member which rotates rapidly under its spring 23 so that the pin 26 drives the blade-ring arm 38 anticlockwise and thus opens the shutter blades 55 pivoted on the plate M at 56 and pin-and-slot connected as at 57, 58 to the blade ring 40. When the shutter is open the bevelled edge of the pin 26 slips past the rounded end of the arm 38 and a second pin 28 on the master member by engaging the edge 39 of the arm then drives the blade ring clockwise closing the shutter. For longer exposures the master member is retarded by a projection 60 on it engaging the tail 61 of a gear segment 62 geared to a star and pallet-wheel device 71, 72, the amount of retardation being determined by the disposition of the tail 61 controlled from a speedsetting member (not shown). Specification 578,971 is referred to.

Title: Animated figure toy
IPC: A63H13/04
Filed: 1956-08-29
Abstract: 792,445. Targets for games; toys. ARMSTRONG, R. E. Aug. 29, 1956, No. 26355/56. Classes 132(2) and 132(3) A toy comprises a base, on which a figure is mounted which includes a movable body pivotally supported to swing downwardly and incorporating a striking implement in an attitude to strike a weight - elevating lever, and a retractable impact receiving device mounted on the base and yieldably held in a projected position, and connecting means between the movable body part and the impact receiving device and operative to cause the movable body to swing downwardly in a striking operation when the impact receiving device is caused to retract. When the button 24 is hit by a disc thrown by hand, the member 27 pivots about 28, and the chain 30 pulls the body part 15 of the figure down about the pivot 17 and the mallet 16 strikes the lever 8, sending the weight 5 up grooves in the stand 3 hitting a gong 4. The distance the weight travels up the stand depends on the force and the angle of application on the button 24. The figure returns to its normal position by the action of a weight 35 and the button projects outwards again by the action of a spring 32. The legs of the figure are cut away to allow free movement of the body part and a rod 33 prevents the member 27 from turning too far when returning to its normal position. The base is provided with friction grip devices 20 to prevent sliding on the support 19 along which the discs are thrown. Alternatively, the base may be integral with the support.

Title: Apparatus for detecting the presence of foreign bodies in or on transparent vessels
IPC: G01N21/90
Filed: 1933-09-25
Abstract: 425,602. Photometric apparatus. STOATE, N. P., 24, Gloucester Court, Kew Gardens, Surrey. Sept. 25, 1933, No. 26416. [Class 97 (i)] [See also Group XL] To detect the presence of foreign bodies on the bottoms of transparent vessels, a light-sensitive cell receives light passing through the bottom of the vessel and an apertured screen moving relatively thereto, the aperture being small compared with the area of the cell. As applied to the examination of milk-bottles, the bottles are fed from conveyers 11, 12 and carried round a table 2 by a rotating plate 6 onto discharge conveyers 13, 14. The table is apertured at 17<a>-17<h>, the apertures being successively radially displaced so that every portion of the bottom of the bottle in its passage round the table is viewed by cells 18<a>-18<h> disposed beneath the apertures. Each cell, e.g. 18<e>, Fig. 3, controls a separate valve 36 whose anode circuit is interrupted by a contact 43 co-operating with a toothed disc 144 rotating with the disc 6. The teeth 144a are such that the anode circuit is only completed when the bottle is fairly over the aperture, to prevent spurious effects due to the thickness of the side walls of the bottle. Each valve co-operates with a separate interrupter except when there are an even number of apertures, when one interrupter may interrupt two anode circuits. The presence of a foreign body on the bottom of the bottle causes actuation of a relay 39 controlling a further relay 48 which steps the motor driving the conveyers and also locks-up over contacts 52. In a modification, interruption of the anode circuits of the amplifying valves is achieved by the use of a second cell 57, Fig. 5, associated with each cell 18 and receiving light via prisms 55, 56 from two apertures 217, 117 radially displaced from the aperture 17. Illumination of the cell 57 causes actuation of relay 62 whose contacts 63 complete the anode circuit of the valve 36 controlled by the testing cell 18. The interruption may also be produced by mechanical trips actuated by the bottles in their passage round the table. A. single cell may replace the cells 17<a>-17<h>, reflectors associated with each aperture projecting the light onto the cell. The light may be derived from one or a number of sources and may comprise extreme red or near violet radiation.
