Title: The manufacture of pure carbonic acid
IPC: C01B32/50
Filed: 1932-03-30
Abstract: Pure carbon dioxide as obtained by reacting basic compounds or carbonates or bicarbonates at an elevated temperature with chromium oxide or substances containing the same or with metallic chromium or alloys thereof.  The process may be carried out in the absence of oxygen with the formation of combinations containing chromium such as chromites, by a dry process in a furnace with an oxidising atmosphere with the formation of mono- or di-chromates or by an aqueous process under pressure in an autoclave provided with an oxidising atmosphere with the formation of aqueous mono- or di-chromates.  The carbon dioxide is separated from the resulting gases in known manner. According to examples, (1) a mixture of chromium oxide and solvay soda is heated in flowing nitrogen or hydrogen to 800 DEG  C., carbon dioxide being formed together with sodium chromite which is decomposed by water into caustic soda, and chromium oxide for return to the process; (2) chromium oxide, sodium carbonate and water is heated to 150--250 DEG  C. with flowing air or oxygen in an autoclave, carbon dioxide escaping and sodium mono-chromate forming; (3) ferrochromium also containing carbon, sodium carbonate and water are heated with flowing air or oxygen in an autoclave, carbon dioxide escaping and sodium dichromate being formed.

Title: Photographic apparatus
IPC: G03B31/02
Filed: 1966-03-04
Abstract: 1,094,280. Recording and playback. EASTMAN KODAK CO. March 4, 1966 [March 8, 1965], No. 9500/66. Heading G5R. A mechanism for use with a sound projector or camera enables the film guiding arrangement, on which a sound transducing assembly is mounted, and which holds the film in engagement with a drive member, to be moved so as to disengage the film from the drive to permit threading operations &c. to be performed, and enables the transducing assembly to be pivotally moved independently of the guiding arrangement so that when the drive is engaged, the transducer may be set to either a sound or silent operating position. The mechanism incorporates a plate 34 which is mounted and spring biased relative to a mounting plate 37 so that it may be moved vertically downwards when a cam 65 moving in an aperture 62 and rotating on a spindle on the plate 37 is rotated through 180 degrees (relative to the position shown in Fig. 2). The plate 34 carries mounting spindles for the wheels 16, 18 which engage the film with the sprocket drive wheel 17. When the cam 65 is fully rotated, the whole mounting plate moves downwards and the drive wheels are disengaged from the film to enable threading &c. to be performed. Mounted on the plate 34 is a magnetic transducing assembly 70 incorporating an erase head 85 and record playback head 94. The assembly is pivotably mounted at right angles to the plane of the plate 34, so that when a nose 60 on an arm 56 engages the top of the head assembly 70, the heads are tilted away, out of engagement with the film sound track. The arm 56 is operated by a cam 66 on the same control shaft as the cam 65. Thus a first rotation of the shaft turns the heads from a sound to silent operating position, while further rotation disengages the whole guiding and holding system from the drive sprocket 17. The assembly 70 incorporates a number of adjusting screws which enable the heads to be aligned laterally with respect to the sound track on the film, and also adjusted for azimuth, parallelism and tangency.

Abstract: 753,751. Rectifying. FKG F. KESSELRING GERATEBAU AKT.-GES. April 2, 1954 [April 2, 1953], No. 9807/54. Class 38 (2). [Also in Group XXXVII] An electromagnetic switching arrangement for synchronously switching A.C., e.g. for rectifying, comprises a combined armature and current bridge 8 co-operating with fixed contacts 12, 13 and has circuit closing and opening assisting electromagnetic systems 15, 16, the current bridge being held in its unenergized position at less than 0.1 mm. from the fixed contacts, and the circuit opening assisting magnetic system being energized not later than the instant at which the alternating voltage across the contacts reverses to cause the distance of the armature from the fixed contacts to increase by an amount at least proportional to the magnitude of the reverse voltage. In a three-phase rectifying circuit having switching chokes 4 associated with each switch 7, the contact 8 is held in the unenergized position by spring 9 on which it is mounted optionally in conjunction with a constant magnetic force. The switch is closed when winding 15 is energized upon occurrence of a forward voltage across the switch and choke, it is held closed by the load current passing through winding 14, and it opens to take up its unenergized position when this load current falls to zero. The reverse voltage now developing across the opened contacts energizes proportionally the winding 16 connected across contacts 12, 13 at P, P1, which moves contact 8 to a position beyond the unenergized position. If winding 16 is connected across the switch choke 4 as well as the switch at P1, P2 it is energized before the start of the current breaking stage so that it assists the actual opening. In the constructing of switch shown in Figs. 2, 3, the contact bridge 33 co-operating with fixed contacts 30, 31 is mounted in armature 32 carried by a spring 35 fixed at its ends to insulators 36, 37 mounted on the fixed contacts. The opening magnetic system comprises two limbs 38, 39 spaced by insulation 40 and carrying respectively opening winding 46 and the holding, load current winding 45. Permanent bias for setting the unenergized position of the armature may be provided by a permanent magnet 55. The breaking E.M. system comprises a core 49 carrying the winding 16, associated with which may be a winding 53 which damps the armature movement in both directions, or one only if a rectifier 54 is provided.
