Title: Process for reducing a non-magnetic iron ore to magnetite
IPC: C21B13/00
Filed: 1962-06-06
Abstract: <PICT:0989548/C1/1> Non-magnetic iron ore is reduced to magnitite by a process comprising contacting said iron ore in particulate form and in fluidized state in a reduction zone into which a reducing gas having a composition such that reduction beyond magnetite cannot occur is introduced, withdrawing a gaseous effluent from said zone and contacting the withdrawn gaseous effluent with particulate iron ore to be passed to the reduction zone, the temperature of the reduction zone being maintained between 800 DEG  F. and 1400 DEG  F. and the gaseous effluent withdrawn from the reduction zone being heated to between 1000 DEG  and 2000 DEG  F. by contact with hot combustion gases prior to being contacted with the iron ore.  As shown, ground haematite is introduced through conduit 10 and is brought into contact with hot reactor effluent gas obtained from cyclone 12 and withdrawn through conduit 14.  The resulting mixture is transferred via 16 to a cyclone 18 when the solids and gases are separated.  The gases are withdrawn through 20, the separated solids being withdrawn through 22 and 24 where they are contacted with hot effluent gas from reactor 26 via 28 and re-heated with the gaseous combustion product from the re-heater 30. The effluent gas from 26 is at 1100 DEG  F., and is re-heated by combustion of natural gas and air in 30, from which combustion gases at 3600 DEG F. are withdrawn via 32.  The mixture of solids and gases in 24 is separated in cyclone 12, the hot reactor effluent gas being used as described above and the solids passing via 38 to reactor 26.  This reactor is of the fluidized bed type and is provided with a perforated grid 40, and an internal cyclone 44 for separating solids and gases equipped with a dipleg 46 for return of fines to the fluidized bed.  Reducing gas, a mixture of air and natural gas which is produced in a partial oxidation furnace 48 is introduced into the reactor 26 via conduit 50, and the haematite in 26 is reduced to magnetite. The magnetite is withdrawn via 56 and its heat extracted in suitable steam generation apparatus 68 to produce steam for use elsewhere in the process.  The exit gas from the reactor is separated in cyclone 18 and passed through conduit 20.  Part is vented to the atmosphere via 21 and the remainder is passed to gas scrubber 60 where it is scrubbed with cooling water.  The aqueous phase is withdrawn from the system, and the gaseous phase, free of entrained material and water vapour passes via 66, part serving as fluidizing gas in the steam generator 68, the remainder being transferred to partial oxidation furnace 48 for mixture with the reducing gas.  If desired, additional trains of cyclones in parallel may be employed to increase the capacity of the system.

Title: 5-nitro-2'-deoxyuridine and the preparation thereof
Inventor: MURTH YELAHANKA KRISHNAMURTHY
IPC: C12R1/225
Filed: 1964-05-27
Abstract: An enzyme is produced by fermenting Lactobacillus leichmannii ATCC 7830 in a culture medium containing an assimilable carbon source and nitrogen source and mineral acid salts. The fermentation may be carried out by incubating the micro-organism at 30-40 DEG  C. for from 6 to 24 hours.  At the end of the fermentation, the cells of the micro-organism are isolated, e.g. by centrifugation, and subjected to disintegration in order to free the enzyme contained in them.  The disintegration may be effected by subjecting a buffered suspension of the cells to the action of an ultrasonic disintegrator; the enzyme goes into solution and can be stored, after separation of the cellular debris, at low temperatures in frozen condition.ALSO:The novel compound 5-nitro-21-deoxyuridine are prepared by subjecting 5-nitro-uracil to the action of the enzyme produced during the fermentation of Lactobacillus leichmannii ATCC 7830, in the presence of thymidine.  Therapeutic compositions having antiviral activity, which may be administered topically, orally or parenterally, contain 5-nitro-21-deoxyuridine as active ingredient.

[Class 40 (i)] [Also in Group I] A machine for hoeing between rows of growing plants is provided with tools 4, the operation of which is controlled by feelers 5 which contact the plant, thereby completing an electric circuit operating the tools. The feelers are mounted straddling the plant row A and each feeler is provided with separate relay circuit 7 which operates a motor 11, upon the earthing of the feeler by a plant, to traverse the tools in such a direction as to break the contact between feeler and plant. Additional electrodes 14 are provided at a higher level to ensure the destruction of tall weeds, the earthing of these electrodes being arranged to prevent traverse of the tools. The circuit (Fig. 2) includes a thyratron 13, the grid of which is negatively biassed by the potentiometer circuit 15, 19, to which the feeler 5 is also connected. Earthing the feeler 5 short-circuits the potentiometer and causes the thyratron to " strike," thus operating the relay 7. This action is prevented when the earthing of the electrode 14 through a tall-growing weed short-circuits the resistance 20. The anode is connected to a tuned circuit 16, 17, forming part of the relay 7 and supplied with unsmoothed direct current by a rotary converter 22, the thyratron arc, once struck, being extinguished when the anode potential next reaches zero.

Filed: 1924-09-20
Abstract: 233,589. Case, W. G. Sept. 20,1924. Air supply, regulating.-In a boiler furnace of the kind in which the air supply damper is controlled by a thermostat immersed in the water of the boiler, the rod of the thermostat is independent both of the bellows of the capsule and of the lever connected to the damper, this arrangement preventing damage to the capsule by any displacement of or shock to other parts of the apparatus. As shown, the air supply damper b is connected by a chain J and adjusting device J<1> to one arm of a pivoted lever H, the other arm of which engages beneath a pin f in a slot formed in the upper end of the thermostat rod F. The latter is mounted loosely in the bellows D of the capsule C and is guided by a boss d, formed on the bottom of the bellows, and a rod d<1> which engage in bars f<1>, f<2>, respectively. In operation, on contraction of the bellows D, due to rise of temperature in the boiler and consequent expansion of the liquid in the capsule C, the rod F is raised and allows the damper b to move, by its 'own weight, towards the closed position; on fall of temperatura in the boiler, the rod F is moved downwardly, and the damper b consequently opened, by a spring G which is enclosed between a flange f<3> on the rod F and the top of a chamber e formed in the casting E which is screwed to the fixing ring A. In the modification shown in Fig. 4, the rod F, slotted to receive the end of the lever H is extended upwardly to operate a thermometer K, the upper end of the rod contacting with the lower end n<2> of a frame N adapted to move vertically in guides n<3>, n<4>.

Abstract: 846,762. Low water alarms for boilers. SULZER FRERES S. A. July 12, 1957 [July 12, 1956], No. 22225/57. Class 123(1) An alarm and safety device for the boiler 1 of a hot water heating system which gives a warning and shuts off the fuel supply when steam instead of water is present in the boiler outlet pipe 3 comprises a hollow body 8 having a connection 17 to the pipe 3 and locating in its upper part a temperature sensitive member 11 connected by a pipe 111 to a thermostat 10. A vent duct 7 including a siphon which prevents a flow of water through the body extends from the top of the body to a point 9 on the pipe 3 downstream of the connection 17. Whilst water is present in the pipe 3, the body 8 is filled therewith and cooling fins 15 on the body dissipate sufficient heat to prevent the member 11 reaching the response temperature of the thermostat. If the pipe 3 contains steam, due, for example, to a failure in the water circulation of the system, the steam replaces the water in the body and the member 11 is heated to above the response temperature. The thermostat 10 then opens contacts 12 to break the supply of current to a solenoid valve 13 which shuts off the supply of fuel to the boiler burners 14. The thermostat also gives a visual or an acoustic warning of the low level by actuating warning lights or sound signals.

Abstract: 886,826. Photographic cameras. VOIGTLANDER A.G. July 14, 1958 [July 12, 1957], No. 22492/58. Class 98(1). A diaphragm, one leaf of which is shown at 21, can be adjusted by two setting members 23, 27, one of these being coupled to a diaphragm-setting ring 11 and the other to the shutter-speed setting ring 10, the latter coupling being such that a constant lightvalue obtains; the ring 10 has an index mark 12 which reads against a fixed scale 13 (giving the shutter-speed value) and another index mark 17 reading against a movable scale 18 (which gives the diaphragm value). Scale 18 is movable by virtue of its being on the ring 11, which also carries a light-value scale 19 reading against a fixed indicator 20. The rings 10 and 11 are retained in any set position by means of respective locating devices 30, 29. The diaphragm 21 and setting members 23, 27 are arranged between the lenses, as shown. Member 23, which has a cam slot engaging the driving pin 22 of diaphragm leaf 21, extends upwards, through apertures in the lens housing 1, 6, terminating in a lug 24 which moves in a slot 25 in the ring 11, said slot running parallel with the optical axis. Thus as the lens housing 1 moves axially under the action of the focusing ring 4, the lug 24 moves in slot 25, so that member 23 and the diaphragm setting ring 11 remain coupled together. Similarly the other setting member 27, connected to the diaphragm leaf by pin 26, is coupled by a long pin 28 to the shutterspeed setting ring 10. The length of pin 28 ensures that coupling is still maintained when the whole of the housing 1, with the lenses and shutter, moves axially as a unit.
