Abstract: 424,273. Extracting iron. JACKSON, L. MELLERSH-, 28, Southampton Buildings, Chancery Lane, London.-(Klockner-Werke Akt.-Ges. ; Castrop-Rauxel, Westphalia, Germany) Aug. 15, 1933, No. 22831. [Class 72] Pulverulent unsintered spongy iron is obtained by mixing 6-12 per cent of fuel with iron ore and then treating the mixture in known manner with reducing gas, preferably a mixture of carbon monoxide and hydrogen, the content of the latter gas being at least 30 per cent. The reduction may be carried out in the tiltable pan apparatus shown in the drawing in which the mixture of ore and fuel is placed in the pan 10, and is heated up to the reducing temperature by the combustion, below the pan, of reducing gas admitted from a pipe 18 and air from a pipe 19. The products of combustions are led away by a pipe 13 in a hood 11 to a preheater 20 for the reducing gas. The supply of gas and air is now cut off and hot reducing gas admitted by a pipe 12. This gas passes through the ore and is sucked away through a pipe 17 by a fan 22 whence it is passed through a second pipe 18 to be burnt below a second pan 10. Gas from the cooler end of the heater 20 is passed through pipes 14 into the hoods 11, and gases from bunkers 15 below the pans 10 are withdrawn through pipes 16.

IPC: F22B1/14
Filed: 1971-04-19
Abstract: 1292236 Vapour generator BABCOCK & WILCOX CO 19 April 1971 [2 March 1970] 22883/71 Heading F4A A vapour generator includes an upright pressure vessel 11 containing a bank of heat exchanger tubes 18 for primary fluid, a shroud 51 defining a flow path 52 for secondary fluid, there being an annular space 55 between the vessel and the shroud, means supplying secondary fluid to the space 55, from the lower end of which it flows into the path 52, from which some fluid may be mixed with fluid entering the annular space, and auxiliary means arranged to discharge secondary fluid into the shroud. The main supply of secondary fluid, from nozzles 30 connected to header 32, which comprises two arcuate tubes (Fig. 3, not shown) is discharged into the space 55 at or near the top of cylinder 19, which constitutes the lower part of the shroud 51, and passes into the interior of the cylinder through openings 22, where it is vaporized by heat from the primary fluid, which may be coolant from a nuclear reactor, passing down the tubes 18. Some vapour passes into upper cylinder 24, where it is superheated, into the upper part 26 of annular space 55, and is withdrawn through outlets 38. Some vapour however passes through opening 28 between the cylinders 19 and 24 and preheats the fluid entering from the nozzles 30, so that thermal shock to the metal is minimized. In the event of a plant shutdown, with the cessation of supply from nozzles 30, auxiliary secondary fluid is supplied directly into cylinder 24 from nozzles 33 until the primary fluid in the tubes 18 has cooled. In the event of a hot restart, vapour from the auxiliary secondary fluid is mixed with the cold fluid entering from nozzles 30 in order to preheat it.

A compound of the first formula above in which X is >CHOH, is produced by reduction of a 4-oxo-piperidinopropyline derivative obtained as above, with a complex metal hydride in an inert solvent.  Compounds of the first formula above in which X represents >NH are prepared by treating a compound in which X is >N-CnH2n+1, and n is 1, as prepared above, with a chloroformic acid lower alkyl ester, and splitting off the carbalkoxy radical from the resulting 3-(4-carbalkoxy-piperazinyl) propylidene derivative by boiling with potassium hydroxide in n-butane.  The product may then be converted to a compound of the first formula above where X is >N-CmH2mOH, by reaction with ethylene oxide, propylene oxide, or chloropropanol. Compounds of the second general formula above are obtained by hydrolysing the reaction product of a compound of formula <FORM:1102685/C2/3> in which Z is as defined above, with a Grignard compound of formula <FORM:1102685/C2/4> in which X1 is as defined above, and Hal signifies a chlorine, bromine or iodine atom.  Pharmaceutical compositions having sedative and neuroleptic properties, and which may be administered orally, enterally, or parenterally, in the form of tablets, dragees, or injectable solutions, contain a compound of the first general formula above as the active ingredient.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 2, 1946.]. [Class 135] In a pilot-controlled pressure relief valve, the discharge of fluid from a pressure chamber 12 through passages 56 to an exhaust chamber 14 is regulated by a main valve 72 integral with a piston 74 sliding in a control chamber 36, which is in communication through restricted passages 80 with the pressure chamber and through an axial bore 78 with an adjustable spring-loaded ball valve 62, adapted, when open, to relieve pressure in the control chamber and thus to open the main valve 72. A piston 82, integral with the main valve, is subjected on one side to the exhaust pressure and on the other to control chamber pressure, so that in the normal or closed position the fluid pressure forces on the main valve 72 and the pistons 74, 82 are substantially balanced. A post 92, opening into the control chamber may be connected to a manually actuated exhaust valve, so that the valve 72 may be actuated independently of the pressure in the chamber 12.

Abstract: Multi-colour paints comprise a dispersion or emulsion of particles of paint, the majority at least of which have a longest dimension not greater than 50 microns, in an aqueous medium free of pigment in the aqueous phase to provide, when applied as a coating, a tough water-resistant film.  The paints may be prepared by adding to an aqueous medium, which is stirred at high speed and may contain a dispersion stabilizer, a first paint of one colour, and subsequently adding to the dispersion so produced a second paint of a different colour, or an aqueous emulsion thereof.  The paints may be applied by spraying.  In Examples, multi-colour paints are prepared by (1) adding to an aqueous medium containing hydroxyethyl cellulose and sodium pentachlorophenate a white paint comprising polybutyl methacrylate, titanium dioxide, organophilic bentonite, white spirit and butyl alcohol and a black paint comprising vegetable black in place of titanium dioxide; (2) adding various proportions of vinyl acetate copolymer emulsions to the multi-colour paint (1) to provide semi-matt and satin finishes; and (3) adding to an aqueous medium containing bentonite a blue paint and subsequently white, yellow and pink paints, said paints comprising polybutyl methacrylate, white spirit, hydrogenated castor oil and titanium dioxide, tinted where appropriate with blue, yellow and red pigments.ALSO:Substrates such as metals, wood, fibre board, asbestos cement sheeting, concrete, plaster, masonry fabrics and paper may be coated with multi-colour paints comprising a dispersion or emulsion of paint particles, the majority at least of which have a longest dimension not greater than 50 microns, in an aqueous medium free of pigment in the aqueous phase to provide, when applied as a coating, a tough water-resistant film.

In a system for stabilizing the frequency of a voltage 13 against a standard frequency 36, a feed-back current derived from a network 37 in the anode circuit of a discharge tube 21, controls a saturable reactor 32 which is biased from a D.C. source 44 and is included in a phase-shifting network 27 which is connected in the grid circuit of the device 21 and is supplied from the source of standard frequency 36. The arrangement is such that upon variation of frequency of the voltage 13 a lowfrequency swing of the anode voltage is produced in phase with the phase swing between the voltages 13, 36 and a 90 degree lagging current is derived from the network 37 to adjustthe grid signal and thereby neutralize the tendency to hunt. In the arrangement shown the frequency of the network 13 is controlled by a rotary transformer 11, the rotor of which is driven by a series motor 19 which tends to maintain the desired frequency in the network 13. In a modification an A.C. generator, the frequency of which is to be controlled, is driven by a D.C. motor, the field windings of which are supplied from a bridge circuit controlled from a discharger device 21 and networks 27, 37 arranged as in Fig. 1.
