Title: Self-fluxing synthetic iron scrap and method of preparing the same
IPC: C21B13/00
Filed: 1957-02-19
Abstract: A method of preparing a self-fluxing iron ore for use as a substitute for scrap comprises at least partly reducing a finely divided ore by gaseous reduction in a fluidized bed, agglomerating the reduced ore without reoxidation, and coating the agglomerates with lime, the final composition of the agglomerates being 1-30% lime, up to 10% gangue, and the balance reduced or partly reduced iron ore.  From 1-20% of lime, which may be as limestone or dolomite, may be mixed with the ore before the latter is added to the reducing vessel and preheated to 1600 DEG  to 1900 DEG F., or it may be added to the reducing vessel.  The reduced ore is cooled, agglomerated, and coated with lime, which may be moistened with water or oil, by tumbling. The product is stated to be satisfactory as an addition to the charge in steel making.

Abstract: 1,248,803. Selective signalling. OWENSCORNING FIBERGLAS CORP. 3 Feb., 1969, No. 5704/69. Heading G4H. [Also in Division G3] Apparatus for linking a data processing unit with a condition to be controlled, includes means for converting an input signal indicating the status of the condition to a data signal, and for transmitting the data signal to the data processing unit, and for receiving and storing an information signal from the latter and generating a control signal in response to it, means for generating an independent back-up signal, means for comparing the back-up and control signals, means for adjusting the back-up signal to enable transfers between back-up and control signals without substantially disturbing the condition being controlled, and means for selecting one of these two signals to control the condition. A digital computer, controlling a process in accordance with a programme, receives the outputs of thermocouples, selected by a multiplexer, amplified, and digitized in an analogueto-digital converter, and produces digital control signals which are converted to analogue form in a first digital to analogue converter and if the converter output, amplified and stored, agrees with the converter input, the converter output is passed by the multiplexer to a selected capacitor store. If they do not agree, a second digital to analogue converter is switched in as a replacement (this also has similar checking arrangements), or a lamp may be lit to warn the operator to switch in the replacement. The outputs of the two digital to analogue converters can also be compared as a check. Each capacitor store can control a respective valve positioner via a field-effect transistor and a 4-position multi-bank switch. This switch selects either the capacitor or a back-up signal generator (comprising a potentiometer and a transistor) to control the valve positioner, and also either of them to feed a meter to indicate the control signal magnitude. A lamp is lit when the backup signal generator is in control of the valve positioner.

[Class 49] Foodstuffs such as meat, fish, eggs, and vegetables are preserved by treating first with hydrogen peroxide and then with carbon dioxide or other preserving gas An aqueous solution containing ¢-30 per cent preferably 5 per cent by weight of hydrogen peroxide may be used, the length of the immersion depending on the strength of the solution. Other solvents may be added to the solution. With the more delicate foodstuffs, the air therein may be at least partially removed by evacuation prior to supplying the gas or the gas may be supplied under pressure, e.g. 2-5 atmospheres, which is maintained for 1-24 hours. The temperature is kept low but above freezing. With other foodstuffs, the air may be displaced from the container by the preserving gas. As shown, the food is placed in a container 1 which is next sealed by a cover 2, a packing 3 being inserted between and held compressed by screws 4 bearing on the upper side of the cover 2, and screwing into rods 6 inserted in eyes 5 on the container. The hydrogen peroxide solution is poured in through a funnel 8 and an opening 7 which is finally closed by a screw 9. A cock 10 in a pipe 11, the lower end of which extends inside to near the bottom of the container, is then opened and preserving gas is supplied from a vessel 15, through a drying &c. apparatus 17 and a pipe 14, and displaces the liquid through the pipe 11, the container being finally sealed. The foodstuff is supported on a perforated plate above the residue of liquid in the bottom of the container. A glass &c. window allows inspection of the contents. The foodstuffs may be stored in a container separate from that in which it is treated, and if the surface of the foodstuff is unable to retain the preserving gas the food may be enclosed in a porous wrapper prior to the treatment and transferred in this wrapper to the tin, impregnated carton, impregnated paper, cellulose foil or other final enclosure.

Title: Improvements in and relating to the production of complex metal carbonyls
Inventor: CHATT JOSEPH
IPC: C07F15/00
Filed: 1960-02-18
Abstract: A complex carbonyl of a metal of Group VIII of the Periodic Table excluding platinum and iridium is obtained by reacting an alcohol with a complex chloride, bromide or iodide of said metal having the metal linked with a plurality of molecules of a hydride of phosphorus, arsenic, or antimony in which all the hydrogen atoms are replaced by hydrocarbon groups which may be alkyl, aryl, aralkyl or alkaryl groups. The process is particularly applicable to the production of complex carbonyls of rhodium or ruthenium. The complex metal halides may be represented by the empirical formula MXy(ER3)3 wherein M is a metal as defined above, X is Cl, Br or I, R is a hydrocarbon group, y depends on the valency of the metal and E is P, As or Sb, for example, [RhCl3(PEt2Ph)3] and [Ru2Cl3(PEt2Ph)6]Cl wherein Et is ethyl and Ph is phenyl. The complex metal halide may be obtained by treating a solution of the corresponding metal halide in water or an alcohol with a hydrocarbon substituted hydride of phosphorus, arsenic or antimony. The alcohol used to form the complex carbonyl product is preferably an aliphatic monohydric alcohol, e.g. methanol, ethanol, propanol or allyl alcohol, and the reaction is preferably carried out in the presence of an alkali, e.g. sodium carbonate or caustic potash.  The reaction temperature may range from room temperature to 100 DEG C. or higher and is preferably near the boiling point of the reaction mixture which may be subjected to elevated pressure. The product is a complex metal carbonyl in which the metal is linked with at least one carbonyl group, at least one halogen or hydrogen atom and a plurality of molecules of the hydrocarbon substituted hydride of phosphorus, arsenic or antimony. If the product contains hydrogen atoms linked to the metal they may be replaced by halogen atoms by treating the complex with a halogen acid, e.g. hydrochloric acid. Examples are given for the production of complexes having the formulae: RhCl(CO)(PEt2C6H5)2, RhI(CO) (PEt2C6H5)2, RhBr(CO)(PEt2C6H5)2, RuHCl (CO)(PEt2C6H5)3, RuCl2(CO)(PEt2C6H5)3, RuCl2(CO)2(PEt2Ph)2, RuCl2(CO)2(PEt3)2, RhCl(CO)(PEt3)2 and RhCl(CO)(PEtPh2)2 and the invention includes said specified products as new compounds. The products are useful as catalysts in oxidation and carbonylation processes.  According to the second Provisional Specification the metal may be any transition element having an atomic number of 21 to 30, 39 to 48, 57 to 80 or 89 to 100 including copper, silver, gold, mercury and rhenium and the halogen atoms attached to the metal atoms may be the same or different. Also, the compound RhH (CO)(PEt2C6H5)2 is specified as product.

Title: Improvements relating to the extraction of nickel and iron from lateritic ore
Inventor: ILLIS ALEXANDER
IPC: C22B23/06
Filed: 1957-02-21
Abstract: In a process for extracting nickel and iron as carbonyls from a lateritic nickel-bearing ore by subjecting the ore to reduction and to subsequent treatment with CO at atmospheric pressure between 25 and 75 DEG C., the reduction is carried out between 500 DEG  and 850 DEG C. in a selectively reducing atmosphere containing CO and CO2 in the volume ratio 3:2 to 1:3 and the temperature and composition of the reducing gas is so correlated that the subsequent treatment with CO yields a mixture of volatilized nickel and iron carbonyls in which the weight ratio Fe:Ni is 2:1 to 1:7.  H2 and H2O may wholly or partially replace the CO and CO2, the equivalent ratio being determined from the equilibrium constant of the reversible reaction CO+H2O\sXCO2+H2.  The iron oxide type ore (i.e. the high ferric oxide-low silica content final product, containing over 40% Fe, of leaching magnesia and silica from the ore by atmospheric water in a warm humid climate) should be reduced at 500-650 DEG C. so that Fe:Ni in the carbonyl mixture is not less than 1:3.  Silicate type ore (i.e. the high silica and magnesia content initial product, containing less than 25% iron, from leaching) should be reduced at 650-850 DEG C. so that Fe:Ni in the carbonyl mixture is not greater than 1:1.  The reduction gas may be CO, CO2, H2, and H2O mixture produced by combustion of fuels, e.g. coal, oil, natural gas, or water gas, in contact with the ore.  The carbonyls are separated by liquefaction and fractionation and are heated to form the metals. The residue from the CO reaction may be leached with ammoniacal ammonium carbonate to extract cobalt and remaining nickel, which may be precipitated as sulphide.  Before leaching, it is preferred to separate the finest powder fraction, e.g. less than 10m , by gas elutriation.

Filed: 1950-03-09
Abstract: 668,792. Venting containers. ARMSTRONG CORK CO. March 9, 1950. [March 26, 1949] No. 5947/50. Class 125(iii). Gas which may develop pressure within a stored container is vented past the screw threads of a closure cap 2 while the container remains sealed against leakage of liquid by means of a packing 3, comprising a thin facing layer 13, an intermediate layer 8 corrugated to provide channels 11, 12, and a backing layer 7. The upstanding ribs of the channels are rendered less rigid either by placing the liner in a flat press or between press rolls. Figs. 3, 4 show liners treated respectively in these two ways. Excessive gas pressure forces the facing layer up into the channels 12, even around the periphery of the liner when the cap 2 is tightly screwed on to the container, the gas escaping by way of channels 12 to the screw threads 6, 24. The backing layer 7, which may be omitted in cheaper constructions, may be made of pulp board, or paper, as may the intermediate layer 13 which may in addition be made from resilient plastics or vulcanized or synthetic rubber. The latter may also be used in making the facing layer 13 as may vinyl resin when it is applied to a sulphate paper carrier. The liner may be stuck to the closure cap which may be moulded or made of metal.
