Title: Process for the industrial extraction of the constituents of natural and artificial silica compounds
IPC: C01F7/24
Filed: 1934-02-12
Abstract: In extracting natural and artificial silica compounds containing alumina, such as leucites, blast furnace slags, alkaline-earth aluminium silicates obtained from bauxites, clays, laterites, or copper and lead water jacket slags, with nitric acid, the acid is added gradually to the mass of material to be treated, and the material is subjected to crushing and mixing and if desired raised temperatures during reaction, whereby the silica is obtained in the amorphous state.  The total amount of acid used is such that the final solution is neutral to methyl orange. After separation of the silica, the solution may be treated with magnesia to precipitate alumina, and iron and manganese oxides, or first with lead peroxide to precipitate iron and manganese and then with magnesia to precipitate pure alumina.  Alumina may be extracted from the mixture of oxides by treatment with caustic soda and precipitation with carbon dioxide, or the mixture of oxides be dissolved in sulphuric acid, and iron and manganese be precipitated with lead peroxide, to obtain a solution of aluminium sulphate.  The solution obtained by precipitating the oxides with magnesia may be treated with dolomite to remove calcium and obtain a magnesium nitrate solution from which nitric acid and magnesia for re-use may be obtained.

Title: An automatic control system for electrical vibrating apparatus
IPC: H02P25/18
Filed: 1943-03-22
Abstract: 573,177. Automatic control systems for electrically vibrated mechanisms. TRAYLOR VIBRATOR CO. March 22, 1943, No. 4669. Convention date, March 28, 1942. [Class 38 (iv)] Weight.-A system adapted to maintain constant the loading of a conveyer, actuated by vibrating apparatus, comprises a magnetic member 33 movable in relation to a magnetic core 30 in accordance with the loading and adapted to control the current supplied to the coils 15 operating the vibrating apparatus. Coils 31, 32 fed with alternating current generate voltages in coils 35, 36 which are normally equal, but vary in opposite senses as the member 33 moves from its mean position. These voltages are applied to the input circuits of amplifiers 23, in pushpull, which, through similar amplifiers 24, produce on the primary winding of a transformer 43 a voltage which is normally nil, but is of reversible phase and variable amount in accordance with the position of the said. member. The coils 15 of a vibratory motor or other control therefor, such as a saturable reactance or transformer, are supplied through a rectifier 13 having a control grid to which is fed an A.C. voltage normally lagging 90 degrees on the anode voltage, and condensers 58 in series in the grid circuit are adapted to introduce a D.C. voltage varying with the position of the member 33 to shift the phase of the ignition instant in each cycle of anode voltage of the rectifier 13 so that the loading of the conveyer may remain constant. A transformer 48 supplies current through rectifiers 25, 26 in opposing senses to resistances 51, 52 so that normally the voltage across their series connection is nil and the transformer 43 superposes on them through the same rectifier, its aforesaid variable voltage. An adjustable resistance network 60 having a tapping 59 is connected in series with the resistances 51, 52 in a shunt circuit charging and discharging the condenser. The effect may be to apply to the grid an instantaneous increment of voltage when the member 33 changes its position or a gradual change in that voltage according as the tapping is to left or right of the network 60 ; both effects are combined in intermediate positions of the tapping. Specification 487,099 . is referred to.

Title: Improvements in or relating to means for locking goods containers on transport vehicles
IPC: B60P7/13
Filed: 1936-02-17
Abstract: 456,401. Vehicles with removable bodies. KELLETT, W. P., 16, Hilltop Road, Bronxville, New York, U.S.A. Feb. 17, 1936, No. 4790. Convention date, Feb. 28, 1935. [Classes 103 (iv) and 108 (i)] The type of apparatus described in Specifications 275,982, [Class 103 (iv)], 356,598, and 390,431, for securing castor-mounted load-containers in position on flat vehicles by means of members swung up from recesses in the floor of the vehicle and adjusted to abut against the ends and sides of the container, is modified by the provision of complementary socket members on the containers into which the turned-up members engage so as to lock the containers positively against vertical, lateral and longitudinal movements. In the form shown the members 4 in the folded position lie under the hinged covers 5 and are completely below the level of the floor while the raised covers also fold down again and hold the raised members in their acting position. Screws 16 in the upper ends of the members 4 are adjusted until their tapered ends 24 abut firmly against the complementary socket members 22<1> on the container 20. Flanges 23 guide the screws into the correct position, and have one side cut away so that the screws can be swung downwards into the non-acting position without excessive axial retraction. For adjusting the screws, a lever 14 is rotated with a ratchet-like action. On the forward stroke, a projection 15 on the lever engages one of a series of notches in the screw and thus rotates the latter. On the return stroke, the lever is swung about the pivot 13 so as to disengage the projection 15. When not in use the lever is passed over a lug and is secured by a padlock passed through the hole 19, thus locking the screw against turning. Similar double-ended appliances 32, Fig. 1, without the screw-adjustment are used between two containers when they are placed end to end on the carrying vehicle.
