Patent GB-762469-A (GB)
Title: Process for the production of ferromanganese
IPC: C22B4/06
Filed: 1953-05-11
Abstract: A two-stage process for the reduction of manganese-bearing mineral products containing oxides of manganese, iron, calcium and silicon comprises subjecting a charge containing the mineral and a carbonaceous reducing agent to a first stage smelting treatment at a temperature sufficiently high to effect reduction of a portion of the manganese oxide to produce a molten mettalic manganese-bearing product and a slag containing unreduced manganese, separating the slag and treating it in a covered open-arc electric furnace with added basic fluxing material and sufficient reducing material to reduce the remainder of the manganese and iron oxide, the temperature of reaction being maintained by combined arc-resistance and slag-resistance heating, the positions of the electrodes being maintained between 1/2 inch above the slag bath and 2 inches below it.  In the first stage ratio of moles of basic oxides, excluding manganese oxide, to moles of silica should be in the range of 1.7-2.2 and should be above this range if manganese oxide is included as a basic oxide.  Preferably the slag product from the first stage should contain 2.0 moles of total bases to 1.0 mole of silica. The amount of carbonaceous reducing agent used is preferably such as to reduce the iron oxide and sufficient of the manganese oxide to leave a slag having the required composition, i.e. containing its manganese oxide in the form of manganese silicate.  Iron or iron oxide may be added to the starting materials of the first or second stage to control the iron content of the metal product. Any addition of iron to the first stage aids the removal of impurities such as phosphorus, arsenic, lead and copper and the production of a purified slag for the second stage reduction.  In the second stage the reducing agent may be non-carbonaceous, or calcium oxide and carbonaceous material may be used whereby a small amount of calcium carbide is formed ensuring complete reduction of manganese.
Patent GB-131336-A (GB)
IPC: C01B21/26
Abstract: 131,336. Gros et Bouchardy, F., (Assignees of Guye, P. A.). June 16, 1917, [Convention date]. Nitric acid.-In the production of nitric acid of about 98-100 per cent. strength from liquid nitrogen peroxide, oxygen, and water or aqueous nitric acid, the nitrogen peroxide is employed in such excess as to maintain the liquid saturated throughout the operation, that is, the ratio of nitrogen peroxide to water is at least 15:1. The action of the oxygen is continued until the lower layer consists of nitric acid of 98-100 per cent, strength containing nitrogen peroxide and the upper of nitrogen peroxide containing a little nitric acid of the same. strength. The oxygen may be employed under pressure, for instance 20 atmospheres, and a somewhat raised temperature not above 30‹ C. may be used. The mixture is agitated during the reaction. The operation may be effected intermittingly or continuously. In the former case, the two layers which form may be separated and the nitric acid layer may be distilled to recover the excess of nitrogen peroxide, while the other layer which is mostly nitrogen peroxide may be used again; or the whole mixture may be distilled together. In the latter case, water, liquid nitrogen peroxide, and oxygen are introduced at B, C, and A respectively in the necessary proportions. The product flows out through S, and the excess of oxygen carrying nitrogen peroxide escapes at F. By heating the lower part E to 50-60‹ C. the peroxide is expelled from the acid and is condensed by cooling the part G. Specification 4345/15 is referred to.

[Also in Division C2] A sheet film cassette has a pair of flexible side panels at least one of which transmits the radiation used to make the exposure and between which the film is clamped during exposure, the side panels tending, when the cassette is open, to assume the general shape of part of the curved surface of a cylinder, being hinged together so the hinge is substantially at the line of contact of the two parallel cylindrical surfaces formed by the side panels when the cassette is open and the side panels deform on closure of the cassette to grip the film in a rolling action progressively away from the hinge being held in a closed position by a latch means to maintain a film under substantially uniform pressure and protected from leakage of light into the space between the side panels. As shown in section in Fig. 4, flexible side panels 10 are supported in channels 21 of frame 20 which frame is adapted to form a latch means, e.g. 26, 28, a hinge 23 and shaped so as to interact when closed to prevent light leakage into the cassette. Preferably pads 39 are secured to the facing surfaces of the side panels so as to be compressed when the cassette is closed, and the pad may be a foam material having a mid-range modulus of elasticity between 0À1 and 9À2 1b./sq. in., the foam being compressed between 20 and 80% when the cassette is closed. The natural curvature of the side panels may be 36 inch in radius, the uncompressed thickness of the pad being 0À3 inch. The pads are preferably of uniform thickness but may also be thicker in the centre. It is preferred that in the closed position the side panels are spaced apart by a distance which is approximately equal to the uncompressed thickness of one of the pads. Intensifying screens 40, may be attached to the pads so they lie adjacent the film 34 when the cassette is closed. The sheets 10 may be fitted with a " back-up " lead foil 37 to prevent back scatters of X-radiation. Alternative latching means are given in Fig. 6 (not shown). As shown in Fig. 3, the frame 20 may be fitted with a slot 30 adapted to permit the insertion of a plug member carrying identifying information to be impressed on the film.
