Title: Production of alkali metal fluotitanates
IPC: C01G23/00
Filed: 1953-05-28
Abstract: Sodium, potassium and ammonium fluotitanates are prepared by heating a titanium dioxide containing material with an oxidic compound of calcium, barium or strontium to at least 1200 DEG  C. to form an alkaline earth metal titanate, incorporating the titanate in 20-50 per cent. sulphuric or hydrochloric acid and heating the mixture to at least 90 DEG  C. in the presence of an added source of fluoride ions and alkali metal ions, separating any insoluble phase while maintaining the temperature and subsequently cooling to crystallize the desired fluotitanate.  Starting materials include ilmenite, brookite, rutile, titaniferous slags or sands. Of the oxidic alkaline earth compounds, calcium sulphate is preferred, but the nitrate or carbonate may be used.  If the silica content of the raw titania is in excess of 5 per cent., a 10 molar excess of the alkaline earth compound should be used. If it is desired to remove iron and silicon during the pyrolytic treatment, an added carbonaceous reducing agent should be present and treatment effected at fusion point to remove the impurities as ferrosilicon.  In the acid treatment of the so formed titanate, the added fluoride and alkali metal components may be present from the start of the acid treatment, but if the silica content is high, an intermediate separation of insoluble silicon and iron compounds can be effected and the fluoride and alkali metal added subsequently.  The fluoride reagents may be in the form of fluorspar, hydrofluoric acid or the fluorides of the alkali metals. The alkali metals may be introduced as sulphates, chlorides or nitrates, in addition to introduction as fluorides. According to examples (1) calcium carbonate and pigment titania are treated at 1300 DEG  C. for 1 hour and the ground titanate sinter is treated with sulphuric acid at 90 DEG  C.  To the mixture is added fluorspar and potassium chloride and the whole digested at 90-100 DEG C., then filtered hot.  On cooling and the addition of a potassium fluoride solution, potassium fluotitanate crystals are formed.  (5) A mixture of ilmenite ore and precipitated calcium carbonate are heated as in (1) above and the ground sinter reacted with 50 per cent. sulphuric acid, followed by digestion at 50-75 DEG C.  On dilution and a short further digestion calcium sulphate and iron hydroxide are separated by filtration. Potassium fluoride is then added and after boiling and cooling, potassium fluotitanate is crystallized.  (8) Calcium titanate, prepared as in (1) above, is reacted with hydrochloric acid and fluorspar, potassium chloride, potassium sulphate and sodium sulphate are added; the function of the sodium sulphate is to hold the calcium sulphate in solution.  After dilution and digestion at 95 DEG C. the solution is filtered and the potassium fluotitanate crystallized.

Abstract: 1,014,854. Control of D.C. motors. ENGLISH ELECTRIC CO. Ltd. April 19, 1962 [April 25, 1961], No. 14908/61. Heading H2J. [Also in Division G3] A flying shear 12 is driven by motors 25, 26, supplied from mercury arc rectifier 27 having grid control gear 28 associated with pattern generator 29 which receives signals from mixer circuit 31 and a current-limiting feedback signal from D.C. transformer 36. The mixer receives a control signal X representing the position of the shear, a signal Y representing the shearspeed, and a signal V responsive to the speed of billet 11. The signals X and Y assist on another and oppose the signal V. A reference control signal P, which is dependent upon the displacement of a predetermined point on the billet from the work-position, opposes the signals X, Y, and assists the signal V. Application of the signals P, V to the mixer commences operation of the shear motors, the signal Y then being generated and also applied to the mixer. Under the control of signals Y, V the shear would be accelerated until the difference between the signals is such as to maintain the rectified voltage at the correct level. However, if the shear is displaced from the exact position required for the cut, signals X and P become unbalanced and the speed of the shear is modified in a corrective manner. The distance that the shear travels during acceleration is allowed for by starting the shear when signal P is exceeded by the signal X plus a portion of the speed signal KV, K being a constant attenuation factor. Amplifier 33 responds when the signal X + KV is greater than signal P so operating switch 34 to connect signals P, V, to the mixer to start the shear motors. At the instant of cutting, the signal P returns to its maximum value, so exceeding the signal X+KV. The amplifier 33 then responds so that switch 35 connects signal S to the mixer, this signal being a fixed voltage which causes slowing down and stopping of the shear blades in a predetermined starting position. The signal P is derived from a digitalto-analogue converter 19 connected to counter 18 receiving pulses from pick-off 16 which are subtracted from a digital number set by length reference source 17. Each pulse generated by the device 16 represents a length of billet passing roller 13.

Abstract: 1399056 Electric selective signalling; label reading system ELECTRONICS CORP OF AMERICA 29 March 1973 [31 March 1972] 15149/73 Headings G4H and G4M A machine-readable coded label (e.g. for identifying articles in an automatic sorting system comprises code marks 20 each disposed in the left or right half of a digit space 22 to represent binary 1 or 0 respectively. The code marks are sensed as the label moves past a scanner which outputs a pulse train 32, Fig. 4 (11011101) which can be applied to a logic circuit such as that of Fig. 3. Pulse 32-1 causes a timer 50 to produce an output 54-1 after time T 2 : since pulse 32-2 is a 1 gate 60 is enabled and a ONE signal 74-1 is output. At the same time, a flip-flop 70 is set: its output 76 causes timer 50 to produce its next output 54-2 after time T 1 . Pulse 32-3 is a 0, so 54-2 and the output from an inverter 64 enable a gate 66 to set a flip-flop 68: when 32-3  arrives it enables a gate 62 and a ZERO signal is output. Flip-flops 72, 70 are set, reset respectively, and timer 50 is caused to produce its next output after time T 0 . This procedure is then repeated for pulses 32-4 ... 32-8. In the logic circuit of Fig. 5 (not shown), a ramp generator (100) establishes the width of a digit space 22 so as to allow for the relative speed of the label and the scanner. A voltage divider (120-124) establishes the “- and ¥-diigt space points, and a generator (102) produces a sawtooth waveform which is compared with the voltage levels set by (100), (120-124) to generate data sampling pulses: a 1 or 0 is shifted into a register (156) according to the sampling result.
