Title: Improvements in or relating to photographic roll film cameras
IPC: G03B19/04
Filed: 1949-06-27
Abstract: 677,135. Photographic roll film cameras. S.C.A.T. SOC. COSTRUZIONE ARTICOLI TECNICI. June 27, 1949 [June 26, 1948; Nov. 9, 1948], Nos. 16996/49 and 16998/49. Class 98 (i). A photographic roll-film camera, having a lens and a shutter and provided with a device for controlling both the film feed and shutter operation, is characterized by a manuallyoperable circular plate adapted to rotate about an axis perpendicular to the axis of the lens and carrying diametrally-disposed projections, one of which is a pawl resiliently connected to the plate and adapted to advance the film when the plate is rotated in one direction, and the other is fork-shaped and integral with the plate and arranged to operate the shutter when the plate is rotated in the opposite direction. As shown, the film is fed and the shutter actuated by a plate 16 secured to a knob 13 rotatably journalled in a frame 17 within the camera body. A lever pivoted eccentrically of the plate and urged anticlockwise by a spring 22 against a stop 23 on the plate, has a tooth 21 which engages in the film perforations to effect feeding when the knob is rotated clockwise, a supporting plate 18 for the film being slotted at 19 to accommodate the tooth 21. Simultaneously with the feeding, a pin 33 carried by the shutter cover-plate 24 and engaged in the forked end 32 of the plate 16, is moved to cover the aperture 36 in the shutter-plate 25. On then rotating the plate 16 anti-clockwise, the longer arm 38 of the fork 32, which is bevelled to slip over the lug 34 on the plate 25 during the clockwise movement of the plate, engages the lug and the fork thus moves the two plates 24, 25 in capping relation across the aperture in the shutter supporting plate 27, while the film feeding tooth 21 trails across the film feed perforations. When the plate 16 approaches its extreme anticlockwise position, fully tensioning the shutter driving spring 37 (Fig. 8, not shown), the arm 38 slips away from the lug 34 so that the plate 25 is driven across the exposure aperture to effect the exposure, the plate 24 being held stationary by the fork 32. A diaphragm plate 26, having different apertures and slidably movable by a knob 12, is mounted in a plate 28, the diaphragm and shutter mounting plates 27, 28 being attached to the camera body by tongues 30, 31. Two plates, one bearing a field lens and the other an eye lens comprising a view-finder, are slidably mounted on the front and rear walls respectively of the camera and are moved to their operable positions by separate knobs.

Title: Process and apparatus for oxidising hydrocarbons
IPC: C07C51/31
Filed: 1961-05-11
Abstract: A process for effecting the multistage aerial oxidation of hydrocarbons particularly naphthalene to phthalic anhydride is carried out in apparatus comprising a vertical tower and means for feeding a reaction mixture through the tower from the top downwards, the tower comprising a plurality of superimposed units each comprising a permeable stage supporting beds of catalyst, a gas-diffusion grid located above the stage and spaced therefrom and a lateral duct for the supply of air opening immediately below the stage of one unit and above the gas-diffusion grid of the next lower unit.ALSO:A process for the multistage exothermic oxidation of hydrocarbons in general, and naphthalene to phthalic anhydride in particular, by means of air comprises bringing a reaction mixture of hydrocarbon vapour and air in successive adiabatic stages into contact with successive quantities of catalyst at a temperature below the optimum reaction temperature, such that in each stage the heat evolved in the reaction raises the temperature of the mixture above the optimum temperature, and then again cooling the mixture to a temperature below the optimum reaction temperature, the cooling being effected by the addition of an appropriate quantity of air and the final mixture, obtained after the last stage, being directed to at least one heat exchanger for recovering the heat content of the mixture.  Examples describe the oxidation of naphthalene by air in the presence of V2O5 at about 350 DEG C. and the oxidation of o-xylene to phthalic anhydride similarly.  Preferably amounts of additional air increase in a geometric progression with successive stages of reaction.  If desired there may be added to the reaction stages air containing hydrocarbon homogeneously mixed therewith.
