Title: Improvements in the Extraction & Purification of Thorium Compounds.
IPC: C01F15/00
Filed: 1919-03-14
Abstract: 127,555. Lindsay Light Co., (Assignees of Ryan, L. W.). May 29, 1918, [Convention date]. Thorium oxide, fluoride, sulphate, and carbonate.-The purification or recovery of thorium compounds is effected by first producing the fluoride and then converting this into the anhydrous sulphate by digestion with sulphuric acid at a high temperature. The acid thorium-containing solution resulting from the digestion of, say, monazite sand with acid, is treated, preferably after a preliminary concentration of the thorium, with hydrofluoric acid or a soluble fluoride in the proportions required to precipitate the thorium as fluoride without bringing down any substantial amount of the rare-earth metals present. The filter-cake is heated at 300-400‹ C with concentrated sulphuric acid. The resulting sulphate of thorium may then be separated from admixed sulphates of the rare-earth metals by treatment with a solution of sodium carbonate or bicarbonate to dissolve out the thorium as carbonate, or by interaction with sodium, potassium, or ammonium hydroxide the resulting thorium hydroxide being purified by conversion into a crystallizable salt such as the sulphate.

Abstract: 844,088. Automatic control systems for jet engines. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Feb. 28, 1958 [March 5, 1957], No. 6571/58. Addition to 769,101. Class 38 (4). [Also in Group XXVI] A ram jet unit as claimed in the parent Specification comprising means for controlling the position of the inlet shock wave so that the fuel supply to the combustion chamber or chambers is decreased when the shock wave moves upstream of its prescribed position and vice versa, and in which the inlet shock wave is maintained between two static pressure tappings has the pressure tapping devices of the control means mounted on a member movable parallel to the direction of flow so that the prescribed position of the shock wave may be varied. In the arrangement shown, Fig. 1, the forward tapping point A of the control means is located on the upstream side of the central body of a ram jet in a position unaffected by the position of the shock wave. The tappings B and C, which are arranged together with the tapping A to control the fuel supply so that the shock wave is between the points B and C are formed in a slide 29 positioned by a threaded rod 30 and support 35. The rod 35 may be rotated by hand or by a device responsive to a variable associated with the conditions of operation of the ram jet e.g. altitude speed of flight, pressure of the fuel supply. The threaded rod may be replaced by a piston in a cylinder operated by the delivery pressure of the fuel suitably regulated by a needle valve. The most favourable positions of the shock wave for different conditions of operation are determined experimentally and marked on a graduated dial 38. The rod 30 is adjusted until the pointer 37 is over the position for the desired conditions of operation. The fuel supply is controlled in the manner described in the parent Specification. A visual indicator of the shock wave position formed by lamps controlled by switches operated by the air pressures is also described. A pneumatic, hydraulic or electric system which may be used to position a second pointer on the dial 38 may replace the visual indicator.

Feb. 28, 1930, No. 6673. Convention date, June 8, 1929. [Class 57.] The flow of mixture to an internal-combustion engine is controlled by a valve situated in the induction pipe between the manual throttle and the engine, and provided with auxiliary closing means arranged between the manual throttle and the governing valve. The valve 10 is of the butterfly type, pivoted at 16 to a housing 11 adapted to be bolted in the induction pipe. The valve is unbalanced so that the flow of mixture tends to close it and the closing is resisted by a spring 30 acting upon a crank 24 on the pivot 16. One end of the spring 30 is attached to a lever 28 pivoted at 28<1> and provided with a cam face 27 contacting with the crank pin 25 such that the spring exerts a force, in any position of the valve, which exactly balances that tending to close the valve. To prevent the valve 10 fluttering it is connected to a dashpot comprising a piston 33 arranged in the cylinder 34 attached to the induction pipe so that one side of the piston is subjected to the induction pressure and the other to atmospheric pressure through throttling passages 41. When the carburetter throttle is nearly closed owing to increased suction on the piston 33, it aids to close the valve 10.
