Title: An improved method for the reduction of iron ore
Inventor: CLEMENT CLAUDE
IPC: C21B13/14
Filed: 1960-07-29
Abstract: Iron ore is reduced in the liquid state by means of reducing gases, such as hydrogen, carbon monoxide, producing gas, water gas, but preferably natural gas or hydrocarbon vapours, in two stages: the first stage enabling the degree of oxidation of the ore, e.g. initially at a value 1.37 after preheating and melting in a furnace to be brought to a value of between 0.7 and 1.2, e.g. 1.01, the value being defined as the ratio, in a given weight of ore, of the total number of oxygen atoms over the total number of iron atoms; the second stage permitting the final conversion of the partially reduced ore into liquid iron.  Each of these two stages comprises one or more phases of reduction, the residual gases of at least one phase having a given degree of oxidation being used to effect the reduction of an ore in a previous phase having a greater degree of oxidation. Preferably, the reducing gases are preheated to above 500 DEG  C. and are bubbled through the molten ore to effect contact therewith. Either all of the successive phases are effected in the same reactor by means of gas having an increasing reducing power or the different phases are effected simultaneously, each in a separate reactor, each of which contains an ore having a degree of oxidation different to that contained in the other reactors and which is fed with the residual gases coming from the reactor in which is treated ore of the immediately lower degree of oxidation except for the final phase reactor to which is fed fresh preheated reducing gas, preferably methane, together with oxygen or air to supply the necessary heat. The oxygen may be introduced in a molecular proportion less than the quantity of methane for treating pure iron oxide, temperature initially at least 1590 DEG  C. to finally 1400 DEG  C., or at the most 0.5 times the quantity of methane for treating ore containing gangue, temperature initially above 1550 DEG  to 1600 DEG  C. to finally above 1520 DEG  C.  Fine particles of carbon or coke may be used suspended in the reducing gases.

The recess may be formed directly in the conductor of the lead and the spring may be moved independently of the reception of the lead.  In an embodiment, Fig. 4, the transverse ridge 4 of spring 5 presses against either one of the recesses 3 of end 2 to give an electrical contact between the leads 1 and the sides 11 of a screw socket terminal 18. The recesses may be diametrically opposed or annular. In another embodiment the terminal is replaced by a U-shape contact (11, Fig. 3, not shown) with both limbs of the U in contact with ends 2, one of the limbs having a protrusion (17) for a recess 3. Another variant makes contact to a single lead (Figs. 1 and 2, not shown). A different form of end piece 23, Fig. 5, may be used having holes 28, 29 for receiving one part of the ridge which is divided into three parts (46, 47, 48, Fig. 6, not shown). The edges 40, 41, of the holes are chamfered at different angles to accommodate the ridge more accurately. The outer parts of the ridge are used in conjunction with an end piece having two pairs of notches (Fig. 7, not shown). Alternatively the ridge is sufficiently narrow to enter wholly the aperture in the end piece (Fig. 8, not shown). Another embodiment (Fig. 9, not shown) has the end-piece turned on its side and having two notches on opposite sides, one (70) for the ridge (57) of the spring and another (68) for a detent in the housing floor.

Abstract: 1,156,331. Casting kerbs. JOHN LAING RESEARCH & DEVELOPMENT Ltd. 24 June, 1966 [26 June, 1965], No. 27186/65. Heading E1S. [Also in Division G3] Concrete from a mobile carriage is layed at a desired level along a route by automatically controlling the height, relative to the carriage, of a gate, tamper and smoother in dependence on signals derived from means detecting the position of a taut wire stretched along the route to provide a datum level. In the arrangement described, a mobile carriage, adjustably mounted on a pair of endless track units so that the tracks may be run at different levels, is driven by hydraulic motors supplied from pumps driven by an internal combustion engine which also drives an electric generator for the control system. Mounted at the front of the carriage is an adjustable hopper 42, Fig. 12, having an opening 43 through which concrete is deposited between adjustable slip forms 44. Also mounted on the carriage (not shown) is a sub-frame 49 having damped feelers 76, 77 spring-urged into contact with the underside of a wire 78 which is stretched between posts 79 along the route to be followed, so that its height corresponds to the desired level of concrete. As the carriage, which straddles wire 78, follows undulations of the ground, angular movements of feelers 76, 77 magnetically actuate switches in units 74, 75 so that reversible electric motors 61, 62 are operated to maintain sub-frame 49 at a height corresponding to the desired level of concrete, which is then obtained by virtue of a vertically reciprocated tamper 47 and a vibrated smoothing plate 48 mounted on the sub-frame 49. A vertically adjustable gate 45 with an automatic wiper is associated with the outlet of hopper 42 and mechanically coupled to sub-frame 49 in such a manner as to maintain a constant compaction ratio. Steering of the vehicle, which is by coarse and fine differential speed control of the track units, may be manual or automatic by feelers, similar to feelers 76, 77, detecting the route of wire 78 instead of its height. A pendulum controlling a reversible electric motor may be arranged to keep the sub-frame level transversely when laying wide strip.
