Title: Improvements in or relating to a process of recovering alumina from aluminous silicious material containing a substantial proportion of silica
IPC: C01F7/22
Filed: 1936-06-20
Abstract: In a process for the recovery of alumina from aluminiferous materials high in silica such as clay, siliceous bauxite, coal ash, blast furnace slag, or feldspar, a portion, say from 5 to 15 per cent, of the initial material is first sintered at say 900--1200 DEG  C., with an alkali metal chloride in the presence of steam to form silico-alkali metal-aluminate and liberate hydrochloric acid, and the remainder of the initial material is then sintered, say at 1100--1400 DEG  C., with an alkaline-earth metal compound, the silico-alkali metal-aluminate, and an alkali metal compound to obtain sodium or potassium aluminate and calcium or other alkaline-earth metal silicate.  The alkali metal compound for the main charge is recovered from the spent lye when alumina is precipitated from the solution of alkali metal aluminate obtained by leaching the furnace product, and the amount of silico-aluminate is calculated to be sufficient to replace losses of alkali in the furnace processes, whilst a substance high in alumina may be added to the charge for the second furnacing operation in order to remedy any deficiency of alumina.  In the first furnacing operation, the proportions are so chosen that 1 to 2 mols. of Na2O are present for each mol of Al2O3, and in the second, that 2 mols of CaO are present for each mol. of silica, and 1 to 1,7 mols. of Na2O are present for each mol. of alumina.  Alumina may be precipitated from the solution of sodium aluminate by the Bayer process, and a portion of the spent lye may be used to dissolve sodium aluminate from the furnace product.

Title: Improvements in method of and apparatus for directive sound transmission
IPC: G01S1/72
Filed: 1920-06-25
Abstract: 146,189. Steward Davit & Equipment Corporation, (Assignees of Hayes, H. C., and Mason, M.). June 25, 1919, [Convention date]. Subaqueous audible signals.-Sound is transmitted in any desired direction by means of a number of sources which are spaced apart and operate in a definite controllable phase-relationship to one another. In the form shown in Fig. 1, electro-magnetic transmitters 1 - - 12, constructed as shown in Fig. 3, are fed from a common supply alternator 20 through time-lag circuits 21, 22, &c., consisting of inductances in series and capacities in parallel, by means of which their relative phases can be controlled. For example, the transmitter 1 is fed through the left-hand branches of circuits 21, 22, 24; the transmitter 2 through the left-hand branches of circuits 21, 22 and circuit 28; the transmitter 3 through the left-hand branches of circuits 21, 22 and the right-hand branch of circuit 24; and so on. The switches 46, 49, &c., which determine the points at which the .current branches through the different circuits, are connected so as to move in unison. When these switches are in their central positions, the current arrives at all the transmitters in phase, and sound is propagated in a direction at right-angles to the line of transmitters, but when the switches are moved to one side or the other progressive phase-differences are introduced between the different transmitters and sound is propagated obliquely, as indicated by the dotted lines. To minimize reflection in the circuits, the impedance of each branch is arranged to be approximately equal to that of the branched circuit into which it divides. The switch 46 is of a two-contact type, arranged to open the time-lag circuit between the two contacts. This is of advantage when the installation is used for directional reception; by throwing a switch 42 the telephones 70, 71 of a headset are connected in place of the alternator 20, and the direction of a received sound can be determined by both the maximum-intensity and binaural effects. The transmitters may be on board ship or on a shore station; they may be in a circle instead of in a line, and may be separately excited instead of from a common alternator ; they may be of non-electric type, the sounds being transmitted through air-columns of variable length. Specifications 146,188 and 146,193 are referred to.

IPC: B65H23/038
Filed: 1952-07-11
Abstract: 731,833. Hollow rollers. KODAK, Ltd. July 10, 1953 [July 11, 1952], No. 17591/52. Class 34 (1). [Also in Group XVI] A roller, for maintaining a web of material in a predetermined lateral path, comprises a cylindrical member mounted for rotation about its axis on bearing means eccentrically mounted with respect to the roller axis on means permitting universal movement of both ends of the cylindrical member. As shown, a cylindrical member 1 forming part of a roller is rotatable about the inner races of ball races 2 having their outer races secured in recesses 3 at opposite ends of the roller. The inner races fit on bushes 5, each bush having a bore 8 disposed eccentrically with respect to the axis of the member 1. The bushes 5 are retained, against flanges 6, by locking-rings 7. Each bore 8 houses a self-aligning ball-bearing 9 clamped against a shoulder 10 by a ring 11 surrounding a stub-shaft 12 secured to the inner race of the bearing 9. If the force applied by the web is uniform along the length of the roller, the roller is rotated about the ball races 2. However, if one edge of the web is under greater tension than the other, the web applies a greater pressure at the corresponding end of the roller, thus causing the bush 5 at that end to rotate about the stub-shaft 12 to equalize the forces applied to the two roller ends by adjusting the inclination of the roller. The two stub-shafts 12 are parallel to, but offset from one another. In a modification, the bearing 2 may be replaced by a sleeve and/or the ball-bearings 9 by a pair of ball-bearings connected to the stub shafts by universal joints to permit tilting of the roller. Alternatively, the shafts 12 may be secured directly to the bushes 5 and be mounted in selfaligning bearings supported by a machine frame.
