Title: Process of Obtaining Alkali Metal Compounds from Mineral Silicates and other Materials containing Alkalies.
Inventor: MOND ALBERT
IPC: C22B26/10
Filed: 1916-09-05
Abstract: 109,105. Mond, A., (Schmidt, W. A.). Sept. 5, 1916. Alkali-metal compounds.-Potassium and other alkali-metal compounds are separated from mineral silicates such as felspar and from other potashbearing substances, by roasting in presence of lime or other alkaline earth and preferably also in presence of sulphurdioxide and oxygen, and cooling the fume to obtain the volatile potassium &c. compounds as condensed particles which are separated in an electric separator. The process may be used in connexion with the manufacture of cement. Clay, lime, &c. are roasted in a kiln 1 heated by a burner 2 in which preferably an oil containing sulphur is burnt. The fume passes by a flue 4 into an electric separator 5 containing collecting electrodes 8 in the form of plates or screens earthed at 16 and discharge electrodes 7 consisting of wires connected to thesecondary winding of a transformer 12 through a rectifier 13. Dust is separated from the fume and falls into the earlier bins 11 and potassium compounds condensed owing to the cooling of the fume are collected in the later bins. The products may be leached to separate potassium compounds or may be passed again through the kiln. The process may be carried out by heating the materials in an ore-roaster kept at about 1000‹ C. and passing through it the vapours from a pyrites burner, or a smelting or other furnace in which sulphur dioxide is formed. Dust &c. may be separated from the vapours before they enter or after they leave the roaster. The vapours which leave the roaster are passed through a tubular cooler and through an electric separator comprising tubular collecting electrodes with axial discharge electrodes.

[Also in Groups XXVII, XXIX and XXXV] An hydraulic or other variable-ratio gear 2 driven from a synchronous or asynchronous motor generator 1 for starting an aircraft gas-turbine engine 3 through reduction gear 18 and a one-way clutch 16, and subsequently being driven as a generator by the engine 3 directly through a one-way clutch 17, is controlled automatically according to the supply current when operating as a motor, to maintain substantially constant the output torque of the motor. In Fig. (Prov. 12735/57), the motor generator 1 has D.C. excitation s2, and its three-phase armature supply s1 passes in series through the stator winding of a power meter 4, the rotor winding of which is energized directly by the supply, whereby an arm 5 on the rotor, biased by a spring 6, moves in accordance with the power absorbed by the motor generator 1 and, through a control 8 adjusts the variableratio gear (which preferably includes zero output speed) to maintain a constant output torque of the motor generator 1, until the engine 3 drives whereupon the motor load becomes zero, the variable gear 2 moves to the end of its range and is subsequently controlled by a governor. In Fig. (Prov. 5442/58) the electrical power absorbed by the motor generator 1 is compared with that of a fixed reference supply 30, 31 and any deviation therefrom is used to operate the control 8 (such as a valve) of the variableratio gear 2 to maintain a constant output torque of the motor generator 1 during engine starting. Current and voltage transformers 23, 22 are used, the former supplying a fixed resistor 24, connecting a centre-tap of the transformer 22 to the junction of two transformers 25, 26 which feeds through bridge rectifiers 27, 28 a resistor 29 in circuit with the reference supply 30, 31. As the current in the resistor 29 rises above or falls below the reference current a polarized relay 210 or magnetic amplifier is actuated in the appropriate direction to operate the variable-ratio control 8 to adjust the motor load. Specification 814,217 is referred to.
