Title: Method and apparatus for controlling a process for cleaning or concentrating ore and carbonaceous materials
Inventor: WHELAN PATRICK FRANCIS
IPC: B03D1/02
Filed: 1952-01-01
Abstract: 720,189. Automatic control systems. NATIONAL COAL BOARD. Jan. 1, 1953 [Jan. 1, 1962], No. 68/52. Class 38 (4). [Also in Groups II and XL (b)] In a method of controlling an ore- or coalcleaning process the output of the process is irradiated with either light or X-rays or radiation emanating from radio-active material, the rays reflected, transmitted or diffused by the output being used to control the process. As shown, Fig. 1, in a froth-flotation process for cleaning coal, the tailings from the flotation machine pass to a tank 2, a thin layer being picked up by the surface of a rotary vacuum filter 3 and dried by an electric heater 4. A beam of light 5 is reflected from the surface of the filter to a photo-cell controlling an electric motor 10 which drives a pump 11 feeding the fine coal to the flotation plant. Thus if the proportion of coal in the tailings is too high the reflected light is reduced and the coal feed is also reduced. Fig. 2 shows an arrangement for controlling a froth-flotation process freeing coal from iron pyrites. A frothing agent, e.g. cresylic acid, and a depressing agent, e.g. lime, are used. Excess of the former or deficit of the latter allows too much pyrites to enter the clean coal. As shown, a continuous sample of the froth is filtered in a wide-mesh cone 12 and the finest particles are removed by a fine-mesh cylinder 13, dried by burners 15, and issue from a cylinder 14 as a dry stream 16. The stream is irradiated by X-rays, the intensity of the transmitted beam indicating the amount of pyrites present since iron disulphide is relatively opaque to X-rays. The transmitted beam controls through a detector 19, amplifier 20 and speed control 21 a motor 22 driving a belt which feeds the lime to the process. Fig. 3 shows an arrangement for controlling the recovery of lead and zinc ores from an ore containing pyrites. A sample of the lead ore froth is contained in a vessel 26 'n which travels an endless metal gauze belt 27. The belt picks up some of the froth and carries it past an electric drier 29. A beam of X-rays is directed at an angle to the belt and a detector 31 is so located as to receive rays scattered from an angle appropriate to the presence of zinc. If the intensity of the scattered beam becomes too high the dosage of sodium cyanide is increased by means of a motor-driven belt 38 controlled by the detector.

Title: Improvements in or relating to Motor Power Plant.
IPC: B63G8/10
Filed: 1916-01-05
Abstract: 100,013. Westinghouse Machine Co., (Assignees of Smith, TV. w.). Jan. 9, 1915, [Convention date]. Motor power plunt.-Motor installations adapted particularly for submarine propulsion and designed to operate efficiently under a wide range of loads include an engine or turbine and an electromotor capable of operating as a generator for charging storage batteries from which it receives current when driving; and the gearing and detachable couplings are so arranged that the propeller shaft may be driven by the engine or by the electromotor, or by both engine and motor; moreover, the engine may drive the motor as a generator either when driving the shaft or not. A number of modifications are described having one or two propeller shafts, each of which is connected through gearing to one or two engines or turbines, which may or may not work in series, and is further connected directly or through gearing to one or two electromotors. Two constructions are shown in Figs. 3 and 10 by way of example. By suitable operation of the detachable couplings or clutches 21, 24, 25, Fig. 3, each propeller shaft 19 may be driven by the turbine 15 through gearing 22, 18, or by the electromotor 16 through gearing 23, 18, or by both turbine and motor; and the turbine may be used to drive the motor as a'generator to charge the storage batteries. The exhaust headers 27 leading to the condensers 28 may extend upwards, Fig. 4, or downwards from the turbine 15. In a modification, the pinions 22, 23 are of different diameters, giving different speed reductions for the turbine and electromotor. In Fig. 10, the electromotor 32 is shown directly coupled to the propeller shaft, and the turbines 31, 42 have pinions 43, 44 gearing with a large gear 18, which is geared to a pinion 45 connected to the motor 32 by a detachable coupling 35, With this arrangement, the propeller shaft may be driven by either or both of the turbine elements (which may be high and low pressure turbines) or by the motor, and the normal speed of each driving-agent may be different. Specification 10374/11 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification, Fig. 8 (cancelled), wherein each propeller shaft is connected on each side to a turbine 31 and an electromotor 39 through gearing 18, 36. The turbines may be connected in series by a pipe 30, and exhaust through a port 34 to a condenser 28. An inlet 41 for astern driving is provided. In another modification, two turbines and one electromotor are associated with each propeller shaft, the turbines being connected to the shaft through detachable couplings and gearing while the electromotor is directly connected to the shaft through a detachable coupling. In a third modification, the propeller shaft is connected through a coupling to a large gear in mesh with three pinions which are respectively connected through couplings to two electromotors and one turbine or engine. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to methods of producing silica sols and aerogels and thecompounds resulting from said method
IPC: C01B33/145
Filed: 1948-01-06
Abstract: Stable silica organo-aquasols are obtained by forming a silica aquasol by the reaction of an acid upon an inorganic silicate and adding a water-miscible organic liquid whereupon the inorganic salt formed in the production of the aquasol is precipitated and removed. Specified organic liquids are methyl, ethyl and isopropyl alcohols, acetone and the methyl, ethyl and butyl monoethers of ethylene glycol.  If a pure aquasol or pure organosol is desired, the organic liquid or water, depending upon which has the higher boiling point, is removed by distillation, preferably under reduced pressure.  Pure aquasols are also obtained by preparing an acetone-aquasol as above and then adding butyl or ethyl acetate when a clear aquasol separates as a lower layer.  Silica aerogels may be prepared by heating the organo-aquasol in an autoclave and slowly releasing the vapours.

Title: Improvements in or relating to electric alternators
IPC: H02K19/26
Filed: 1947-01-06
Abstract: 633,091. Automatic regulation. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S. Jan. 6, 1947, No. 438. [Class 38 (iv)] The output frequency of an alternator is maintained substantially constant irrespective of the speed of the alternator by compensating speed variations by rotation of the exciting field in one or other direction at a speed corresponding to the difference-frequency between the speed frequency and the constant frequency of a master oscillator. In the arrangement shown in Fig. 1, an alternator having a single phase stator 3 and a two-phase rotor 2 drives a tachometer generator 10 having a D.C. field 11 supplied from a master oscillator at 14 through rectifiers 12 and four stator windings 15-18 which generate voltages 90 degrees phasedisplaced. These voltages are independently added in a transformer 32 to a voltage on winding 27 derived from the master oscillator and the resultants are rectified by rectifiers 19-22. The pairs of resultant voltages which are phase-opposed are then applied to the grids of pairs of amplifiers 23, 24 and 25, 26 to produce in the supply lines to the rotor, twophase voltages of difference frequency, when there is lack of synchronism between the alternator speed and the correct output frequency. Thus, when the speed is correct, the rotor field rotates at the same speed as the rotor but any change of speed causes relative rotation of the rotor field so as to maintain the output frequency constant. In a modification, a three-phase rotor is provided, the supply to the rotor being derived from the difference currents from the master oscillator and a three-phase exciter driven from the' alternator. Comparison is effected through phase-shifting networks and mesh-connected grid-controlled rectifiers. The phase-shifting networks are also subject to bias voltages dependent on the ratio of the circulating currents in the rectifiers and the alternator field currents, so as to ensure that the circulating current is greater than the peak amplitude of the field currents to keep the rectifiers output above zero. Specifications 589,526, 597,882, 602,870 are referred to.

Title: Production of zirconium sulphates
IPC: C01G25/06
Filed: 1956-01-05
Abstract: A soluble basic zirconium sulphate is produced by heating under superatmospheric pressure zirconium dioxide, sulphuric acid and water, the molar ratio of said mixture being from 2:3:0.7 to 2:3:3. By adding sulphuric acid to dissolve said sulphate and make the resulting solution strongly acid, and allowing the solution to stand, Zr(SO4)2.4H2O operates as a crystalline precipitate.  The reaction of the oxide with sulphuric acid preferably is carried out at 300-380 DEG  C. and the autogeneous pressure is normally employed, in examples by the use of a bomb. Pressures of 2-80 ats. are mentioned. After treatment of the basic product with concentrated sulphuric acid and separation of the hydrated sulphate, the resulting liquid can be diluted and reused to form more of the basic salt and thus avoid loss of zirconium material.  Unconverted ZrO2 can be recovered by refurnacing.  Examples of the invention are given, and a comparative example discloses the use of a ZrO2:H2SO4:H2O rati of 1:2:2.
