Title: Improvements in or relating to Ore Extraction.
Inventor: BAETZ HERBERT BARCLAY
IPC: C01F7/04
Filed: 1966-02-17
Abstract: 1,180,912. Extraction of Fe, Ti, and Al. H. B. BAETZ. 14 March, 1967 [17 Feb., 1966], No. 7069/66. Headings C1A and C1N. Iron is extracted from a material of high silica and low iron content by treating it with gaseous sulphur and chlorine (elemental or intercombined), at a temperature below which Si chlorides or oxychlorides are formed, to vaporize FeCl3, then converting the FeCl3 into Fe2O3 and recycling the Cl2. The material may be a laterite ore containing Fe, Ti, and Al, which is precalcined e.g. at 500 C., or a steel slag containing Fe and Ti. The Ti and Al are also vaporized as chlorides and may be separated by admitting Sand Cl2 at increasing temperatures, e.g. 320 C. for Fe, above 450 C. for Ti, and above 550 C. for Al. Alternatively, the S and Cl2 may be admitted at 600 C. and the gas mixture passed through a sublimator at 300- 305 C. where FeCl3 and S condense, and then through a liquid TiCl4 scrubber where the TiCl4 liquefies and the AlCl3 condenses as a precipitate. The FeCl3 is separated from the S by passing Cl2 through at 100-150 C. to form SCl2. The FeCl3 and AlCl3 are roasted in air to form Fe2O3 and Al2O3; the TiCl4 is vaporized, mixed with air, and oxidized in a flame at 800-900 C. to form anatase, or at 1000 C. to form rutile 0À25-3 Á in size. The residual gases after chloride separation (SO2 and Cl2), the exhaust oxidation gases (Cl2, O2, CO2 and N2) and the SCl2 are all passed into a S scrubber where the Cl2 reacts to form SCl2 and possibly S2Cl2 (which are recycled), and the remaining gases are passed to an H2SO4 plant. Reference is also made to the recovery of Hf, Ga, and Zr if present.

IPC: H01H35/14
Filed: 1952-03-19
Abstract: 727,034. Inertia switches. PYRENE CO., Ltd. March 19, 1953 [March 19, 1952], No. 7113/52. Class 38 (5) A crash-sensitive device for fitment to aircraft and operable only in response to rapid change in acceleration comprises two fluid-filled chambers defined in part by a resilient wall and joined by a restricted connection, the change in pressure at an end of the connection due to a rapid change in acceleration being detected by a pressureresponsive member to operate a switch. The device, Fig. 1, comprises two liquid-filled chambers 2, 4 each defined by a rigid tube 6 and cup 8 and a resilient diaphragm 10, the chambers being connected by a narrow bore 12 in a plug 14. A weight 16, slidable in guides 18 is connected to one of the diaphragms 10. Bellows 24, 26 connected to the chambers 2, 4 at opposite ends of the connection 12 operate a contact-carrying lever 28 pivoted at 30. If the device is moving in the direction 22 and suddenly brought to rest pressure builds up in the chamber 2 but decreases in the chamber 4 due to forces acting on the liquid 15 and the weight 16, and the flow of liquid through the connection 12 not being sufficient to balance the pressure at the two ends thereof. Hence the greater pressure in the bellows 24 causes the contact 32 to engage contact 34. A second fixed contact may be provided beneath the contact 32 to enable the device to be fitted facing either towards the front or rear of the aircraft (Fig. 2, not shown). The plug 14 may alternatively comprise a number of fine parallel bores- (Fig. 3, not shown), may be fitted with a spring-loaded valve which closes the bore when the pressure attains a certain value (Fig. 5, not shown), or (Fig. 6, not shown) may have a normally-closed spring-loaded valve which, after cessation of a rapid acceleration, opens a connection in parallel with the restricted bore to permit easy equalization of the pressure. Each diaphragm 10 may have a weight 16. In an alternative construction (Fig. 7 not shown) the weight 16 is omitted and the diaphragms constitute side walls (not end walls) of the two chambers. According to Fig. 8 the two chambers 62, 64 are bounded by a common diaphragm 66 loaded with a weight 68. In other arrangements (not shown) the diaphragms may be replaced by pistons, and the bellows 24, 26 by diaphragms, pistons, or Bourdon tubes. According to Fig. 9 (not shown) the contact-carrying lever 28 is supported solely by pivotal connections with the ends of the bellows 24, 26. In Fig. 10 the chambers 72, 74 comprise bellows 76 and the switch contact 78 is operated by a single bellows 80 influenced by the pressure at one end of a connection 82 formed by an orifice in a plate. A gas filling may be used instead of liquid. Specification 681,847 is referred to.
