Title: Process for reducing the ferric oxide content of ferruginous ore materials
IPC: B03B1/02
Filed: 1948-10-06
Abstract: <PICT:0658199/III/1> At least the major portion of the ferric oxide content of a ferruginous ore is reduced to magnetite by repeatedly circulating through a re-entrant circuit containing the ore, a mixture of nitrogen, carbon dioxide, water vapour and carbon monoxide of specified carbon monoxide-dioxide composition, discarding a minor fraction of the gas which has passed through the system and has become depleted in its carbon monoxide content, adding a gas rich in carbon monoxide to maintain the above composition, the amount of carbon monoxide so added being from about 0.6 to a little in excess of 1.12 cu.ft. per lb. iron content, and maintaining the ore at 500 DEG  F. to the liquidus point, partly at least by heat generated and transferred by said mixed gas, the volume of mixed gas being adjusted, between 5 and 30 cu.ft. per lb. ore material to have a heat capacity sufficient for adequate heat transfer. The said gas composition is such that the CO2/CO+CO2 ratio falls within the Fe3O4 stable area in the equilibrium diagram of the ternary system Fe-C-O, the said ratio and temperature being the co-ordinates.  A suitable apparatus comprises a reversible blower 1, regenerative stove 3, reactor 5, regenerative stove 7.  With a gas circulation as depicted, reducing gas is fed through line 10, draft air and fuel gas through lines 14 and 16 respectively, and bleed gas from line 13. In the reverse flow, reducing gas, draft air, fuel gas and bleed gas traverse lines 11, 15, 17 and 12 respectively.  The fuel gas may be identical with the reducing gas, although natural gas or fuel oil may be used.  Stove 3 is originally preheated to 600-2000 DEG  F. Reactor 5 may be a multiple hearth, rotary or vertical shaft furnace. The apparatus of Specifications 647,490, 652,098 and 658,200 may also be used.

Filed: 1926-10-23
Abstract: 264,454. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Butcher, C. A.). Jan. 16, 1926, [Convention date]. Cut - out arrangements; electromagnetic switches.-In order to obtain finer selectivity in the operation of the circuit-breakers of a number of parallel-connected D.C. circuits so as to ensure that only the faulty circuit is cut out, the circuit-breakers 21, Fig. 1, in the circuits 10 - - 15 supplied by the generators 3, 4 are lock controlled by a relay 28, Fig. 2, which closes the tripping circuit in accordance with both the current value, and the rate of change of the current in its parallel feeder. The rate of increase of current is greatest in the faulty feeder and in consequence this is cut out first; the removal of the fault causes a decrease of current in the remaining feeders and this produces a countertorque in the remaining relays, which are therefore positively held from closing. The relay comprises a core structure 29 magnetized by a winding connected across a series resistance 26 in the feeder 10 and a moving coil 30 (wound on a metal former which produces a retarding action) controlled by two centralizing springs and energized from the secondary of a current transformer 25 so that it carries a current which depends upon the rate of change of the current in the feeder. With excessive change as will occur on fault, a contact-arm 31 on the moving coil engages one or other of the fixed contacts 32, 33 and completes a local circuit for the coil of a self-maintaining relay 34 which through the back contacts 36 on the circuit-breaker completes the circuit from the local supply to the trip coil 35. Very heavy overloads bring out the circuitbreakers 17, Fig. 1, and introduce the resistances 18.

Abstract: 506,986. Moulding vehicle doors synthetic resin articles. AUTO UNION AKT.-GES. Sept. 12, 1938, No. 26634. C'onvention date, Sept. 11, 1937. [Class 103 (ii)] [Also in Groups IV and V] A process of manufacturing a vehicle door consists in first forming a partially hardened self-supporting shell comprising a thin-walled panel portion and a peripheral rim portion of synthetic resinous substance containing disintegrated undirectionally arranged fibres, then positioning thereon reinforcing members of a material saturated with synthetic resin and finally subjecting the assembly to heat and pressure to unite it and complete the heathardening. The reinforcements may be preformed of material similar to that of the shell or may consist of laminated material (e.g. superposed strips of plain or crÛpe paper) saturated with synthetic resin. The shell is formed by suspending a mixture of disintegrated waste paper and synthetic resin in water over a sieve mould contained in a vat and then creating a partial vacuum in the bottom of the vat so that a layer of the mixture is deposited on the sieve. The deposit then undergoes a felting action and, after removal of the sieve, is subjected to preliminary heat and pressure to exclude moisture and moult it to the shape of the shell. As applied to the door shown, the shell is formed as a panel 1 and rim portion 2-5, the rim 5 being formed with recessed 16, 17 for receiving rubber buffers, the rim 2 with screw holes 22, 23 and the rim 3 with a screwhole and a recess (shown dotted) along its centre portion. Laminated reinforcements 6-11, which may engage recesses, are positioned so as to radiate from parts 12, 13 of the rim 3 adjacent the door hinges. A strip 14 of laminated material is then placed in the recess in the rim 3 and is covered by a plate 15 of laminated material or of synthetic resin containing fillers in irregular distribution, recesses being left for the door hinges. Laminated reinforcements 24, 25 and 26 are applied adjacent the screw holes, and sharp corners are rounded off by quantities of material 18, 19, 20, and 21 of synthetic resin containing fillers in irregular distribution. The whole is then subjected to considerable heat and pressure in a hydraulic press. The sieve marks in the outer surface of the panel 1 may be covered by a layer of pure synthetic resin.

The inter-register U.F. signalling system disclosed in Specification 1,122,141, where each digit is transmitted only upon the acknowledged receipt of a digit prefix signal, is modified so that in the event of the first digit being transmitted before the receiving register is seized due to an imitation of the signal acknowledging the first digit prefix signal, the receiving register upon being seized recognizes the situation and requests the transmitting register to begin the first digit signalling sequence again so that it may be properly conditioned by the first digit prefix signal; previously the receiving register in this situation would have been rendered impotent and timed out. With reference to the drawings, if the acknowledgement has been imitated, receiving register B on being seized immediately receives the U.F. digit signals on two of receiving relays RA to RF, but without relay FP having previously been operated by the abortive prefix signal. The corresponding transfer relays TA to TF operate and via their contact tree TA2 to FT2, to check the exclusiveness of the two digit signals, and unoperated contacts FP4, DOK5 extend earth to two signal relays SX and SZ which cause transmission of the repeat dialling request signal. At register A the receiving relays then set transfer relays TX and TZ which operates relay AOK over the contact tree TU2 to TZ2. The subsequent release of relay B, which had previously been operated by the bogus prefix acknowledgment signal, operates signalling relays SE, SF to retransmit the prefix signal which after valid acknowledgment by register B is followed by the first digit signal once again since as the request signal had not been stored in relays ASX and ASZ due to the modified contacts TX1 and TZ1 and therefore the setting of the digit controller DSCE had not been effected. The digit transmission can now proceed normally.
