Patent GB-668269-A (GB)
Title: Improvements in and relating to the manufacture of triple-superphosphate
IPC: C05B1/04
Filed: 1947-09-22
Abstract: Triple superphosphate is produced by intimately mixing ground phosphate rock with phosphoric acid, preferably of 34/40 per cent strength, until a slurry is formed, which is passed to a slowly moving inclined surface whose speed of movement is so adjusted that the slurry, retained thereon until after passing through a porous mass phase, is disrupted into particulate form by chemical and physical action.  The slurry may thus be delivered to an inclined endless belt conveyer, the inclination of which is adjustable, the granules from the discharge end passing to a dryer in which they are hardened.  Alternatively, the slurry is fed to a slowly revolving rotary conditioner whose wall constitutes the slowly moving inclined surface, and thence to a second faster moving rotary conditioner wherein granulation of the disrupted product is completed.  Fines from the usual screen apparatus may be returned to the discharge end of the mixer.  The ground phosphate rock employed may be subjected to differential air separation, the finer fraction passing to the reaction mixer and the coarser fraction to the phosphoric acid production plant as described in Specification 620,590. Specifications 503,352, 559,482, 596,782, 625,863, and U.S. Specification 2,070,582 also are referred to.

IPC: C03B23/213
Filed: 1925-10-15
Abstract: 241,890. Jenaer Glaswerk Schott & Gen. Oct. 21, 1924, [Convention date]. Welding and jointing.-A device for facilitating the attachment of an extension to a glass vessel, such as the fusion of an exciting tube on to the bulb of a rectifier, comprises holders for the vessel and for the extension, means for rotating the holders in unison with one another about the same axis, and means for inclining the vessel to the axis of rotation. Construction. The device comprises a base a on which is cast a bearing a<1> for the journal b of an arcshaped guide c. A semicircular carriage d slides in the guide c and is thus free to move about a centre e which lies in the axis of rotation of the guide c. The glass vessel u is supported on the carriage by means of a seat hand by a spring-pressed hood g<1> on one end of a tube g. A flexible pipe k<1> connects the tube g with an axial boring b<1> in the journal b, and this communicates in turn with a supply pipe k<2>. The carriage d may be held in various positions relative to the guide by means of a latch i. The glass extension v, which is to be attached to the vessel u, is supported by a tubular holder t journaled in a bearing o<2> and so arranged that its axis is in line with that of the journal b. The bearing o<2> is mounted on a carriage o which may be traversed along a guide table a<10> by means of a hand-wheel p, the movement of the carriage being parallel with the axis of the journals b, t. Both journals are geared with a shaft i in such a manner that rotation of the shaft rotates both the journals in unison with one another. Operation. In use, a rectifier bulb, say, is mounted between the seat h and the hood g<1>, the carriage being so positioned that a glass tube in the holder t is normal to the surface of the bulb. The bulb is heated at the point of fusion by means of a burner held in the hand, and the hot glass is expanded and burst, to form an aperture in the bulb, by means of compressed air supplied through the pipes k<2>, k'. The carriage o is now moved to bring the tube v into contact with the bulb, and the joint is completed by rotating the bulb and tube while heating the joint with the blowpipe. When the joint is completed. the carriage d can be moved around the centre e to enable the tube u to be set at any predetermined angle to the bulb.

Filed: 1971-04-19
Abstract: 1323251 Treating molten metal C F NIEHAUS 19 April 1971 [13 April 1970] 25967/71 Heading C7D  Molten metal is treated continuously in a tilted reaction vessel which is rotated to produce surface and sub-surface mixing in the bath. Molten metal and a treating ingredient are continuously added to the top of the bath and treated metal is withdrawn from the top portion of the bath adjacent the upward facing inner wall at the front of the reaction vessel at a position spaced from the position at which untreated metal is introduced. The invention may be applied to continuous desulphurizing or recarburizing of molten iron, continuous refining of copper matte to form copper, production of alloys and refining and mixing of copper alloys. Apparatus shown is useful in the oxygen converter refining of pig iron to produce steel. Molten pig iron is introduced through inlet spout 13 to vessel 10. Fluxes such as lime and fluorspar are added to the top of the bath and oxygen is blown in through a lance 19. As shown in Fig. 5 the inner surface of the vessel has diametrically opposed plane portions 30, 31 connected by curved wall portions 32, 33 and has opposed inclined lower portions 34, 35. This conformation produces strong downward currents 50 and upward currents 51 when the planar portions are at the back and front of the tilted vessel. Treated metal overflows at the front, i.e. lowermost part of the vessel rim through a spout 14 which extends round the rim, and is removed for further treatment through a spout 16 connected to hood 21. Two or more such vessels may be operated in series to perform separate operations successively on metal flowing therethrough.

[Class 74 (ii).] In knitting fabrics with solid diamond or like patterns on Cotton's or other straight-bar machines two carrier rods C<1>, C<2> each carrying a set of yarn guides are used to each breadth. The guides on the carrier rod C<1> may be threaded alternately with different colours. By having an extra guide on the carrier rod C<1> for each breadth and shogging accordingly the colours may be alternated vertically and horizontally. The guides on the rod C<2> make the ground diamonds D and may be threaded with the same colour throughout. The triangular areas D<1>, D<2> are made by selvedge carrier rods C<3>. C<4> the inward traverses of which are variably controlled by a band of pattern cards. These with others controlling the rods C<1>, C<2> pass over cylinders mounted at one end of the machine on a common shaft E<2>. The cards operate on pins G<9> carried by bell cranks G<3>, G<4> to which are pivoted droppers G<1>, G<2>. The lower ends of the selected droppers form stops for controlling the traverses of the carrier rods. The inward traverse only of the rods C3, C<4> has to be variably controlled and this is done from a single band of cards. Two bands are required for controlling the rod C<1> to obtain colour alternation. The rod is passed from the control of one band to the other by cam wheels which lift the right-hand droppers and stop corresponding to the left-hand band out of action when the left-hand droppers and stop for the right-hand band are in action and vice versa. The rocking of the cam wheels is controlled by one of the card bands, which also puts in an idle or drawback course after a row of diamonds with colours crossed has been knitted.
