Title: Process for electrolytic oxidation
IPC: C01F17/00
Filed: 1968-02-05
Abstract: 1,209,991. Electrolytic oxidation. CINCINNATI MILLING MACHINE CO. Feb. 5, 1968 [Feb. 15, 1967], No.5620/68. Heading C7B. A solution of a thallium (I) or cerium (III) salt, e.g. the sulphate, is oxidized by passing the solution into the cathode compartment of a divided electrolyte cell, removing the cathodically generated hydrogen and passing the solution into the anode compartment of the cell in which oxidation of said metallic ion occurs to form the thallium (III) or cerium (IV) salt, removing the anodically generated oxygen and recovering the resultant oxidized metallic ion solution; the cell being divided by a membrane which whilst it impedes the back-migration of the oxydized metallic ion into the cathode compartment, permits transport of hydrogen ions through the membrane; and the electrode materials being essentially inert and such that the cathode has a sufficiently low hydrogen over-voltage to prevent reduction of the metallic ions, e.g. platinized platinum or platinized titanium, and such that the anode has a sufficiently high oxygen over-voltage to effect the oxydation of the metallic ions, e.g. lead, platinum, platinized platinum or platinized titanium. The electrodes may be supported between pairs of plastic grids. The membranes used may be of reinforced anion or cation exchange resin, microfibreglass matting or microporous membranes of polypropylene or P.T.F.E. Oxidation of the metal ions may result from an oxidizing agent formed at the anode-electrolyte interface, e.g. lead dioxide or activated oxygen. Cells may be assembled to operate in parallel, pumps and surge tanks being provided for passage of the electrolyte.

Abstract: 741,178. Magazine gramophones.. DEYOLA JUKE BOX CO., Ltd. June 2, 1954 [March 2, 1953], No. 5762/53. Class 40(2) In an automatic gramophone, records are stacked in parallel planes perpendicular to the plane of the turntable and are moveable together transversely to their.planes until a selective device causes one record to be moved arcuately in its own plane and then tilted in one or other direction at will to the plane of the turntable. As shown, the holder 17 of each record 18 is supported on a pivot (not shown) projecting radially from its own tooth wheel 12, these wheels being so supported on spindle 20 that by moving arm 25 they can be moved as a whole until the desired wheel is in one of two positions in front of the arcuate rack 14 which is driven through links 27, 29, 76, 75 from shaft 59 when cam follower 71 is over the part of track on cam disc 67 inwardly from its periphery. Shaft 59 also carries a cam disc 66 the non-peripheral part of the track of which causes cam follower 71 to move arm 39 angularly across the path of a set of pins (not shown) simultaneously with the movement of arm 25 causing the axial movement of the record carriers. The number of these pins which may be remote controlled equals the total number of record sides, and the arm 39 moves until stopped by the selected pin whereupon the appropriate wheel 12 will be correctly positioned for rotation by quadrant 14 which'then operates since cam wheel 67 (also 66) has continued to rotate. Each wheel 12 can come to rest in either of two axial positions, e.g. 57 or 58 (dotted) in Fig. 4 depending on which of the two pins per record has been engaged by arm 39 and accordingly the pin 80, will enter cam track 81 or 82 thereby determining which side of the record is uppermost as it turns into the horizontal position, there being one pin 80 per record holder. The arm. 39 has a spring operated dog (not shown) co-operating with cam 47 so that stopping of arm 39 by a pin enabled cam follower 48 to continue to move until it arrives at a medial position along the concentric portion of the cam track at the time the record is placed on the turntable, the followerremaining in this position while the record is being played, the driving motor 65 of the shaft having been switched off when the tone arm mechanism is operated. Further operation of the latter when playing has ceased. restarts motor 59, causing follower 48 to move into part 70 of its track to cause re-engagement of the dog on arm 39 and return that and the record traversing assembly to return to their zero positions.

Abstract: 964,288. Pneumatic conveyers; discharging. hoppers. FAWKHAM DEVELOPMENTS Ltd. Dec. 18, 1962 [Feb. 16, 1962; Oct. 22, 1962], Nos. 6124/62 and 39910/62. Headings B8A and B8S. Material from shoot 13, Fig. 1, is fed into reactor 10 by the vibration of tray 16 effected by vibrating motor 21, and the feed is regulated by a detecting device 39 such that the height of material inside shoot 13 is sufficient to maintain a seal to withstand the difference of pressure between reactor 10 and shoot 13. Detector 39 has air passed continuously through it from source 42 and the pressure within is measured by gauge 44. When the material inside shoot 13 mounts so that it chokes the bottom of detector 39, the pressure within the detector rises and influences the gauge 44 to cause the vibrator 21 to come into action and to feed more material into reactor 10. Any material which falls from tray 16 over its edges is blown into the reactor by an air jet 36. In modifications the vibration frequency may be varied by the detector to control the rate of feed. The shoot 13 may itself be vibrated or the vibration tray 16 replaced by a belt or scraper conveyer controlled from the detector.
