Title: Improvements in and relating to photographic cameras
IPC: G03B17/02
Filed: 1959-01-27
Abstract: 909,456. Photographic cameras. VOIGTLANDER A.G. Jan. 27, 1959 [July 4, 1958], No. 2934/59. Class 98 (1). A photographic camera, preferably a reflex camera, comprises a manual adjusting member for two trains of transmission gearing to be adjusted simultaneously and in a related manner; one of the trains has parts coupled together by meshing teeth so that there is play, while the other is constructed free of play but with an adjusting device by means of which play equal to that of the other train can be introduced. In the embodiment shown, adjustable rings 4, 5 for exposure time and stop value are adjustable simultaneously in the same direction by the rotation of a shaft 20 acting through a movable ring 23 and pinion 25 rotatably mounted on ring 23, or in opposite directions by rotating ring 4. The shaft 20 is connected through tooth wheels 29-32 to a wheel 45, projections 46 of which rest in notches 38 of a cylinder attached to wheel 32. A disc 50 couples a film sensitivity disc 58 and a cam disc 41 to the wheel 45. The follow-up pointer of an exposure meter is connected to a spindle which can be rotated indirectly by the cam disc 40. A tooth 53 can be disconnected from teeth 47 of wheel 45 and when disc 50 is then rotated the film sensitivity indicator 58 moves with respect to index 60 and the follow-up pointer is also moved to a position corresponding to sensitivity. When tooth 53 engages teeth 47, rotation of wheel 45 rotates both the follow-up pointer and the rings 5, 4 by a corresponding amount. In order to introduce the desired extra play into the cam 40 and follow-up pointer train, prongs 54 of disc 50 which move in aperture 55 of cam 41 are bent outwards or inwards by a requisite amount to delay rotation of said cam, if a light filter is used. After the shutter has been adjusted disc 45 is rotated further using reference marks 43 on cam 41 and a scale on the camera housing.

Abstract: 688,233. Rolling. MASCHINENFABRIK MEER AKT.-GES. Feb. 8, 1951, No. 3129/51. Class 83 (iv). In work-rotating means on a feed device of a step-by-step hot rolling mill for tubes with a rotatable pawl holder, the holder is driven from a constant speed motor through an infinitely variable gear. A twist spindle 1 carries a ratchet-wheel 3 with which co-operate pawls 5 on a carrier 8 rotated by a worm 12, through bevel gears 15, shaft 16, bevel gear 17, and infinitely variable reduction gear 20 comprising two oil hydraulic pumps, the primary pump 23 being driven from a constant-speed motor 21. At the commencement of rolling, with no axial movement of the work between passes, the hydraulic gear 20 is set to rotate the spindle 1 and hence the work through 90 degrees between passes, but as rolling progresses and axial movement is imparted to the work to cause rotation thereof through relative movement with the spindle 1, the hydraulic gear is set to progressively reduce the oscillation of the pawls and so maintain a constant oscillation of the work between passes. In a modification the motor 21 and gearing 20 are arranged on the movable feed device 10, or the motor and primary pump 23 may be stationary while the secondary pump is mounted on the feed device and oil-fed through telescopic tubes or the like. Other forms of infinitely-variable gearing may be employed.

Title: Improvements in the hydration of acetylene to acetaldehyde
Filed: 1930-01-31
Abstract: In the hydration of acetylene and acetaldehyde by means of a mercury catalyst in acid solution containing ferric sulphate as an oxidizing agent, the latter is regenerated by maintaining a circulation of the acid liquor through the hydration vessel, withdrawing a portion of the liquor preferably continuously to a separate vessel in which it is treated with substantially pure molecular oxygen, thus reoxidizing the ferrous sulphate formed in the hydration to the ferric state, and returning the treated liquor to the main circulation.  Preferably at least one third of the hydration liquor is withdrawn, so that by the complete reoxidation of the ferrous iron contained therein the ratio of ferric to ferrous iron in the hydration vessel may be maintained above 1 : 2.  It is desirable to maintain a sufficient concentration of ferric iron to prevent the formation of metallic mercury.  The hydration of the acetylene and/or the oxidation of the liquor may take place either in a packed tower, or with vigorous agitation in a suitable container.  The stream of oxygen gas used for the regeneration may be made up to the required strength and recirculated, inert gases being removed by withdrawing a portion of the gases continuously or periodically. The temperature of the liquor in the oxidation process is preferably maintained between 20 DEG  and 70 DEG  C.  The whole process may be carried out at pressures above or below atmospheric, but atmospheric pressure is preferably employed.ALSO:In the hydration of acetylene to acetaldehyde by means of a mercury catalyst in acid solution containing ferric sulphate as an oxidizing agent, the latter is regenerated by maintaining a circulation of the acid liquor through the hydration vessel, withdrawing a portion of the liquor preferably continuously to a separate vessel in which it is treated with substantially pure molecular oxygen, thus reoxidizing the ferrous sulphate formed in the hydration to the ferric state, and returning the treated liquor to the main circulation.
