Title: A method of recovering tantalum and niobium from oxidic mixtures containing impurities
IPC: C01G35/00
Filed: 1956-10-25
Abstract: Tantalum and/or niobium are recovered from mixtures containing their oxides together with other oxides by extracting the tantalum and niobium in the form of fluorides by means of a ketone containing hydrofluoric acid.  The ketone is preferably methyl isobutyl ketone or methyl ethyl ketone.  The process may be carried out either by passing the ketone containing HF through the mixture, or by stirring the mixture into the ketone containing HF, or by dispersing the mixture in the ketone and then adding HF. The ketone extract may then be treated with water, which may contain HF, in order to obtain an aqueous niobium-rich phase and a ketonic tantalum-rich phase.

Convention date, Nov. 28, 1929. [Class 56.] Rolling.-Relates to the method of making plate or sheet glass in which molten glass is poured from a pot on to a lower rolling-member which may consist either of a table or a roller. According to the invention, the backward flow of the glass, after being poured, is limited by a stop bar e, Fig. 1, having its front face, which comes into contact with the glass n, made concave towards the mass of glass. The position of the stop-bar may be adjusted, towards or away from the rolling- pass f, in accordance with the volume of glass to be rolled. The bar is also moved up to the roller c during the progress of the rolling operation, and its inclination is varied during the progress of the rolling, as shown in Fig. 2, in order to modify the contact of its front wall with the mass of glass. Fig. 3 shows the invention applied to a doubleroll machine. The axis of the upper roll c may be swung about that of the lower roll b, as described in Specification 346,601. The bar e is also rotatable about the axis of the roll b in order to bring it nearer the roll c. It is also rotatable about its lower edge in order to vary its inclination to the surface of the roll b.

Abstract: 175,111. Wylie, H. N. Nov. 25, 1920. Frame components, applying and combining; sheet-metal frames.-A girder, strut, or other member, applicable to motor vehicles and the like, is composed of thin sheet-metal members, such as A, B, connected longitudinally near their edges, each member being bent in longitudinal oppositely-directed curves, which meet at an angle to each other or run into each other by other curves of small radius. This angular junction, as shown at E and C, or the small radius connection, as shown at D, is stated to resist crinkling. The structure may be further strengthened by transverse stiffening-frames, such as G, and, where these are riveted together, a longitudinal groove may be formed in the sheet metal to prevent crinkling near the rivets.

Title: Aerosol detection
IPC: G01N21/53
Filed: 1971-07-15
Abstract: 1342266 Photo-electric aerosol detection TELEFONAKTIEBOLAGET L M ERICSSON 15 July 1971 [24 July 1970] 33378/71 Heading G1A In an aerosol detector including one measuring chamber 11 arranged for rapid and another 12 for slow entrance of aerosol from the surrounding air a photo-cell arrangement 51/52 receives radiation beams that have travelled through the respective chambers to produce a signal indicating comparative aerosol concentration in the two chambers. The light path from a constant or fluctuating source 3, e.g. a glow-lamp, halogen lamp, gaseous discharge tube or light-emitting diode, includes crossed polarizers 6, 7 and a photo-cell 5. In the absence of aerosol, plane-polarized light resulting from polarizer 6 does not pass through polarizer 7 and hence there is no photocell output. If an aerosol, caused e.g. by a fire in a building, enters the light path through apertures 2 in the casing, the polarization state of each beam is changed and some radiation falls on the photo-cell. The two beams terminate on respective concentrically-arranged photo-cells (51, 52) connected in a bridge Fig. 5 (not shown). An aerosol penetrates to the outer path more quickly than to the inner one (through openings 9) and hence the bridge becomes unbalanced. An alarm is actuated if the unbalance signal exceeds a pre-set threshold. A plurality of the aerosol detecting arrangements may be provided in a single building.

Title: Process and apparatus for separating and collecting carbon black
IPC: B04C9/00
Filed: 1957-10-28
Abstract: <PICT:0824749/III/1> In the separation of carbon black from hot gaseous suspensions, by passage of the suspensions through a series of separating chambers, carbon black collects in hoppers attached to the lower ends of the separating chambers from whence with one exception it is removed together with sufficient reaction gases to carry the carbon black as a gaseous suspension, by a common conduit leading to the one separator chamber not connected to the common conduit, from whence it is collected.  A carbon black furnace 1 supplies a hot gaseous suspension of carbon black to a cooler 2 provided with water-sprays 3 whereby the suspension is cooled to about 500 DEG  F. The cooled suspension passes through 5 into an agglomerating chamber 6, which is an electrostatic precipitator, from the upper end of which the suspension passes through 7 to a cyclone separator 8 connected in series with cyclone separators 10 and 12 by conduits 9 and 11.  Residual gases from the separator 12 may pass through 13 to a bag filter 14 where gases are freed from final traces of carbon black and are then discharged through 15. Portions of carbon black collect in the hoppers attached to the bottoms of the agglomerator the cyclone separators and the bag filter if used. Carbon black is sucked into the common conduit 16 by fan 17, through conduits 16, 18, 19 20 from hoppers 6, 10, 12, 14 together with sufficient reaction gases to produce a gaseous suspension.  The reaction gases released into 16 are controlled by adjustable orifices 24.  The gaseous suspension is pumped by 17 through conduit 21 to the cyclone separator 8, where carbon black is deposited in the hopper which is provided with gas lock valve 22 and discharge conduit 23 for removal of the carbon black. Operations of the process in the absence of an agglomerator, with feeding of the gaseous suspension to a separator other than the first for separation of the carbon black, or with incorporation of an additional cyclone separator before the agglomerator are referred to.  Specification 742,187 is referred to.

Title: Improvements in heat treatment processes employing fused solids as heat transfer media
IPC: C21D1/48
Filed: 1937-12-04
Abstract: 512,771. Heating systems and apparatus. SEAILLES, J. C., and SYLVANY, R. Dec. 4, 1937, No. 33642. Void. Convention date, Dec. 4, 1936. [Class 64 (ii)] Apparatus such as tunnel ovens are heated by. direct radiation from the surface of a fused solid. The heating medium may circulate by thermo-siphon, or by impulses derived from the induction of electric currents in it, or by injection of gases, or by the movements of a refractory body dipping into it. The medium, e.g., a metal, alloy, or a salt, may be fused by a burner or electric arc. If the furnace atmosphere is oxidising, the metal may be one whose oxide is easily reducible, and a reducing agent may be present in the metal-heating chamber. Cast iron may be used since the contained carbon is oxidised before the metal and it may be recarbonised in the heating zone. To avoid the presence of carbon gases, copper, tin or bismuth may be used. The combustion products of a single furnace may be used, at successively lower temperatures, to fuse cast iron, tin, and bismuth-lead-tin alloys. The metal 4 is fused by an electric arc employing electrodes 5, 6. The metal circulates through a heating chamber 1 in a stream 9, 10 around a refractory block 2. Leakage of metal is prevented by employing walls of sufficient thickness to ensure solidification of the metal before reaching the outer side, or by cooling passages 11. The surface of the molten metal may be protected by a layer of slag or a refractory slab, and a neutral gas may circulate between the metal and the slab.
