Title: A process of producing alumina from clay and other aluminiferous minerals
IPC: C01F7/24
Filed: 1928-01-13
Abstract: 309,621. Buchner, M. Jan. 13, 1928. Aluminium nitrate and oxide.-Clay, bauxite, and other aluminiferous materials not containing appreciable amounts of potassium or other alkali metals are digested in nitric acid, if desired after preliminary calcination at say 400-800‹ C., aluminium nitrate is separated from associated impurities in the solution so obtained by precipitation by means of concentrated nitric acid or oxides of nitrogen, if desired with simultaneous evaporation of the solution, and the nitrate decomposed by heat to obtain. alumina and oxides of nitrogen which are used in the separation of the nitrate, the acid liquor thereby obtained being used for digesting more raw material. The precipitated nitrate may be washed with concentrated nitric acid. Alternatively the solution of aluminium nitrate obtained may be evaporated, if desired under reduced pressure, or cooled to obtain a solid or pasty mass of crystals which are then washed with gaseous or concentrated nitric acid to remove impurities. The alternative method of purification may be applied advantageously to a solution of basic aluminium nitrate obtained by using a deficiency of nitric acid, or by adding bases such as alkalies, alkaline earths, or alumina to the nitrate solution, or by evaporating the latter to remove nitric acid. Raw materials such as bauxite containing impurities such as iron may be pretreated with dilute or concentrated acid, for instance with hydrochloric acid, to remove such impurities, and solution of the aluminium content of the material may be facilitated by first making up a paste with nitric acid and allowing it to stand at a low temperature with or without stirring prior to heating with addition of more nitric acid. The solution step may be effected under pressure in vessels made of acid proof alloys, such as alloys of iron, chromium, and nickel or alloys of tungsten, and the solution obtained be subjected to pressure, if desired after concentration thereof; in each case the temperature aud pressure may be increased step by step. Decomposition of the aluminium nitrate may be effected in the solid state or in solution, if desired in two stages, preferably in vacuo and with the introduction of water or steam. Alumina may be added to the nitrate to be decomposed, or decomposition be effected in a melt or liquid; for instance, in salts such as sodium or calcium nitrate, or a mixture of sodium and potassium nitrates, and with the introduction of air, oxygen, steam, or other gases.

Abstract: 1,057,102. Air cushion vehicles. D. K. WARNER. Jan. 13, 1964. No. 1399/64 Heading B7K. A ground effect machine for operation over water has stabilizers ahead of its centre of gravity, one on each side of the longitudinal centre line, each stabilizer comprising a V- section strut connecting the body of the machine to a larger hydrofoil (42) (Fig. 2, not shown) and a further V-section strut depending from the larger hydrofoil to which is fixed a smaller hydrofoil (43). In operation the water level is between the two hydrofoils, and if the lower one leaves the water or the upper one enters it, the change in lift provides a sufficient restoring force. Each hydrofoil has two steps, and ram air may be directed to the space behind each step. The further strut may be retractable within the upper strut, and the upper strut may be pivotable forwardly and upwardly to avoid damage by grounding, and may be turned for steering. The air cushion is formed by ram air pressure, but when starting, auxiliary rockets (18) (Fig. 2, not shown), retractable within the body, may be extended into the cushion space and fired. The machine has front and rear aerofoils (24, 39) extending between sidewalls (25) within the cushion space, and in another embodiment (Figs. 13 and 15, not shown) the rockets are replaced by steam ejectors (48a) within the front aerofoil (24), the steam being produced in a liquid oxygen-aviation fuel fired boiler (32). The aerofoil (24) has front and rear flaps (50, 55) in its top surface which are raised to form a passage through which air is drawn by the ejector. The aerofoils (24 and 39) also have lower surface flaps (23, 64) to reduce leakage from the air cushion until the cruising speed of the machine is reached, and these are urged against the air cushion pressure by pneumatic actuators (28, 68 respectively) (Fig. 6, not shown) supplied by air reservoirs (29, 69). Further flaps (37) (Fig. 13, not shown) may be extended from the body to contact the upper surface of the rear aerofoil (39).
