Title: Improvements in or relating to a roll film photographic camera
IPC: G03B19/04
Filed: 1956-12-14
Abstract: 812,744. Photographic roll-film cameras. KODAK Ltd. Dec. 14, 1956 [Dec. 16, 1955], No. 38178/56. Class 98(1) In a roll-film photographic camera having a shutter of the type including a pivotally mounted shutter blade resiliently connected to a pivotally mounted cover plate for an exposure aperture, during rotation of a film winding member a part movable therewith operates on oscillatable member which thereupon first operates the cover plate and blade to tension the shutter and then becomes disconnected therefrom for free movement during further rotation of the film winding member, and the shutter is held in tensioned condition by holding means which when released by operating a shutter trigger, allows the exposure operation of the shutter. As shown in Figs. 1 and 2, a shutter blade 14 with an opening 15 is pivoted at 13 to a support plate 11, in which an exposure aperture 12 is formed. A cover plate 16 is pivoted at 17 to plate 11, and overlies the blade 14. A spring 19 is connected between lugs 18, 19 on the cover plate 16 and the shutter blade 14 respectively. The film-winding shaft 26, which terminates in a knob 27, is journalled in a plate 25 perpendicular to the plate 11 and carries a cam 28, Fig. 6. A shuttle 29, consisting of a flexible plate pivoted at 30 to plate 25, has a flange 32 which is urged against a cam 28 by action of a spring 33. When the film-winding knob 27 is turned, cam 28 causes shuttle 29 to oscillate about its pivot 30, and a flange 37 thereon engages a flange 40 on the cover plate 16, which is moved from its "released" position (Fig. 1) to its "set" position (Fig. 2), carrying shutter blade 14 with its through action of spring 19. A shutter trigger 43 has an arm 45 with. an inclined end 46. As the cover blade 16 moves to "set" position, a lug 47 thereon passes under the end 46 and springs up to engage its inner edge 49 to hold the cover plate 16 and the shutter blade 14 in "set" position. Further rotation of knob 27 does not affect the shutter members. Another arm 41 of the trigger 43 passes through a slot in plate 11 and terminates in a fingerpiece 44. When the finger-piece is pressed, arm 41 is rocked, and with it an extension 55 terminating in a shoe 56, which moves flange 37 out of the path of flange 40. Further movement of arm 41, which is shared by arm 45, results in the release by its end 46 of lug 47, so that cover plate 16 returns to its "released" position under action of a spring 58, uncovering the exposure aperture 12. Spring 19 is tensioned until it passes a dead centre position, whereupon shutter blade 14 quickly follows cover plate 16, closing the exposure aperture again. Actuation of the release 44 before the film wind is prevented by a lever 65, pivoted at 59 on plate 11, and urged by a spring 66 to engage extension 55 by means of a lug 70. In this position the end of lever 65 blocks the path of a lug 74 on arm 41. When the shutter is set, however, an edge 75 of the cover plate 16 engages lug 70 and rocks lever 65 clear of the path of lug 74.

Title: Making filters
Inventor: RUBACK SYDNEY
IPC: A24D3/02
Filed: 1964-09-18
Abstract: Smoke filters for cigarettes are made from a thin web of discontinuous fibres impregnated with particles of a fusible resin by condensing the web to a sliver and heating the fibres of the sliver by direct contact with steam to cause the resin particles to adhere thereto before the sliver is further heated to bond the fibres together.  The sliver can be wrapped and cut into lengths in a conventional plug-making machine and the plugs heated, e.g. in a high-frequency dielectric heater to bond the fibres.  The fibres may be of cotton or regenerated cellulose.  If the resin be nonhygroscopic, the hygroscopicity of the product can be controlled by varying the proportions of fibre and resin. Alternatively, two resins may be employed, one for bonding and the other of low meltviscosity to block parts of the available hygroscopic surface. Suitable resins are polyvinyl acetate, polyethylene, low-melting polyhydrocarbons or polyester.ALSO:Smoke filters for cigarettes are made from a thin web of discontinuous fibres impregnated with particles of a fusible resin by condensing the web to a sliver and heating the fibres of the sliver by direct contact with steam to cause the resin particles to adhere thereto before the sliver is further heated to bond the fibres together.
