Patent GB-1103142-A (GB)
Title: Process for selective extraction of a metal from aqueous chloride solutions containing two or more metal chlorides
Inventor: GRAVENOR CONRAD PERCIVAL
IPC: C01G1/06
Filed: 1964-02-14
Abstract: At least one metal chloride is precipitated from chloride solutions by (a) generating HCl gas in a reducing zone by the H2 reduction of a metal chloride to metal form, (b) utilizing the off gas mixture of HCl + H2 as a source of HCl for introduction to the chloride solutions and (c) utilizing the chloride solutions as a scrubber for the H2 of the off gases and returning the scrubbed H2 to the reducing zone.  Iron chloride present in the solution can be oxidized to increase the ferric content of the solution and to retain ferric chloride in solution during precipitation and separation of the other metal chlorides.  The iron chloride and other metal chlorides may form a complex in the solution with the HCl.  Iron or organic matter can be introduced into the solutions to establish a ferrous content. Metal chlorides precipitated may be reduced in the reducing zone. One or more precipitated metal chlorides can be dried in oxygen to provide oxides of the metals, the remaining metal chloride(s) can be separated by dissolving in water.  The examples relate to the precipitation of chlorides of Fe11, Mn, Ni, Pb, Sn, Cr, Co, Mo, Al and Cu from solutions containing some of these compounds and chlorides of Fe111 and/or Co.  The remaining FeCl3 solution can be hydrolysed in a hot gas stream to give Fe2O3 and HCl gas.  The Specification indicates that the solutions may contain Ti, Ca, Zn and V.  The chloride solutions may originate from mineral ores, waste or scrap materials, e.g. tin cans.

Title: Improvements in or relating to electrically driven remote position indication or control arrangements
IPC: G08B9/00
Filed: 1952-03-12
Abstract: 717,346. Control of D. C. motors. GODWILLMAN, A. March 10, 1953 [March 12, 1952], No. 6432/52. Class 38(3) A remote control system comprises a reversing switch S which, when moved from neutral contact N to forward contact F, completes a circuit from battery B over cam-operated switch G to energize solenoids 1, 3. An electric motor M is thus started with its armature connected in series with field winding W and resistor R. After a predetermined period, the resistor R is short-circuited by means of a time-delay relay P. A motor-driven cam C eventually opens the switch G to disconnect the motor which continues to rotate however due to inertia, thereby closing switch H and operating solenoids 2, 4, for reversing the drive. The switch H is re-opened to stop the motor before the load begins to reverse, the resistor R being included in circuit during the oscillating period. When the switch S is returned to the contact N a circuit is completed over switches J, K, to connect the motor for return to its neutral position in which switch J opens to stop the drive. Operation of the motor in the reverse direction is effected by actuation of the switch S to engage contact A. The arrangement described may be extended to provide a system having seven positions of the switch S for controlling the operation of the cam to a corresponding number of positions, Fig. 7 (not shown). The cam C may be circular or in the form of a rack driven by a pinion. The application to forward and reverse control arrangements for ships is referred to.

[Also in Group XIX]  Data characters, each of which consists, in adata-processing system, of a certain number of binary digits, are translated into a different code using a greater number of binary digits for serial storage, so that the number of consecutive like digits in any sequence of characters may be reduced, hence limiting the required low-frequency response of reading and writing circuits and obtaining more frequent cross-over pulses for maintaining the accuracy of a self-clocked read-out system such as disclosed in Specification 875,374. An example is given in which 63 data characters are each represented in the first code by six binary digits (111111 not being used) plus a check digit to make the bit total odd, and in the second (magnetic storage) code by eight digits of which four are 1's and four 0's (allowing a check) and no more than three successive digits are the same, so that in no sequence of characters will more than six consecutive digits be alike.
