Title: Process for extracting the metal in the form of oxide from the pyritic ores
IPC: C22B3/00
Filed: 1920-07-02
Abstract: Pyritic ores are heated under air pressure in the presence of "chloro-nitrous products" with sulphuric or hydrochloric acid. The product is leached with water or with sulphuric or hydrochloric acid, an alkaline earth chloride is added if sulphuric acid was used, so as to obtain chlorides, and if iron is present it is oxidized and precipitated.  The metals are precipitated in succession by electrolysis or as carbonates by an alkaline or alkaline earth or ammonium carbonate, the carbonates being separated and, if desired, calcined to yield oxides.  When magnesium carbonate is used, the magnesium chloride obtained as a residue is calcined to obtain hydrochloric acid for use in the process; and when ammonium carbonate is employed a slight pressure of carbonic acid is used in the precipitation which may be effected with the chloride or sulphate solution, and the ammonium salt solution is either boiled with lime or calcium carbonate, or is electrolyzed hot in a closed apparatus, carbonic acid being supplied when necessary for the regeneration of ammonium carbonate.

Title: Improvements in and relating to means for indicating at a distance electrically
IPC: G08C15/10
Filed: 1928-07-02
Abstract: 293,459. British Thomson-Houston Co., Ltd., (Assignees of Franklin, C. S.). July 7, 1927, [Convention date]. Tell-tale apparatus. - Relates to methods of indicating at a distance the readings of meters &c. 4, 5, 6 in which the moving parts are associated with frequencyvarying means, such as condensers, which are successively connected, as by a distributor 20, to an alternating current source 3 to control the frequency thereof, and at the indicating station a single indicator, or a corresponding series of indicators, is supplied in succession with currents having a frequency dependent on that of the source 3. The currents may modulate a high-frequency current at 1 as described in Specification 291,092. In order that the accuracy of the frequency-determining circuits may be ascertained, a current of predetermined frequency is periodically transmitted to the indicating station. Variable condensers associated with the meters 4, 5, 6 are connected to contacts 11, 12, 13 of the distributor 20, intermediate contacts 23, 24, 25 being connected to a fixed condenser 19 which determines the frequency of the generator 3 during these intervals. The keying circuit 26 of the high-frequency generator 1 is controlled by the distributor arm 20', which engages a series of long contacts 12<1>, 13<1>, 14' corresponding to the contacts 11, 12, 13, and a series of divided contacts 23<1>, 24<1>, 25<1>, &c. which interrupt the keying circuit two, three, four, &c. times and so determine the position of the selector arm 61 at the indicating station and thus the indicator 33, 34, 35 connected to the output circuit 31, 32 of the detector 30. As the arm 20<1> passes over the divided contacts 23<1>, say, the keying circuit is interrupted three times, say, these interruptions being repeated by relay 42 to the stepping magnet 38 of the selector 60 which closes the circuit of a self-locking relay 43 to connect up the corresponding indicator 33. The selector 60 has considerable inertia so that it is not restored to normal by its spring during short interruptions of the circuit of the magnet 38. While the arm 20' is passing over the divided contacts 23<1>, 24<1>, 25<1>, the intermittent energization of the motor magnet 38 causes a slow-release relay 55 to connect a special indicator 36 to the detector, in order to check the normal frequency of the source 3 as determined by the condenser 19. Instead of using a series of indicators 33 - - 36, a single indicator 68, Fig. 3, may be permanently connected to the detector circuit and a. series of lamps 70, 71, 72 connected up in turn by the selector to indicate which of the meters 4, 5, 6 is in circuit, a special lamp 69 being connected up by the slow-release relay 55 during the test periods. Specification 293,027 also is referred to.
