Title: Rapid direct reduction method of iron oxide
IPC: C21B13/14
Filed: 1961-04-19
Abstract: <PICT:0979053/C6-C7/1> Iron oxide is directly reduced by hydrogen gas in a two-stage process comprising a primary reduction of fine iron oxide, e.g. haematite or magnetite, in a low temperature zone of 450-600  DEG C. subsequent to a secondary reduction in a high temperature zone of 700-900  DEG C. to completely reduce the remaining oxide and obtain a fine sponge iron powder which may be sintered to render the iron stable against oxidation.  The oxide may be lateritic ore, converter flue dust or mill scale, and the hydrogen gas may contain up to 20% by volume of CO, N2 and/or CH4.  As shown in Fig. 6, fine iron ore, e.g. of size between 16 and 250 Tyler mesh is fed via a hopper 6 into a preliminary reactor 8 and reduced by 10% at 300-400  DEG C. It is then transferred to a low temperature reactor 10 and reduced by 80%, the remaining ore being reduced completely on passing to a high temperature reactor 11, the temperatures being as above.  The resulting iron is discharged through a waste heat recovery unit 12 where it is cooled to 300-400 DEG C.  The hydrogen gas, initially heated to 900-1100  DEG C. in a gas heater 17, flows countercurrent to the fluidized iron ore through the three reactors via cyclone separators 15, 14 and 13 respectively to a heat exchanger 24 where it is cooled to 150-200  DEG C. before passing to cooler 27. The gas is then recycled with fresh hydrogen added through a refrigerator 28 back through the heat exchanger 24 and unit 12 to the gas heater 17.  Shaft, horizontal or retort furnaces may be used for the reactors.

Title: Improvements in Gyro-compasses.
Inventor: HENDERSON JAMES BLACKLOCK
IPC: G01C19/38
Filed: 1916-10-17
Abstract: 112,636. Henderson, J. B. Oct. 17, 1916. Gyroscopic compasses.-In compasses comprising two mutually interacting gyroscopes, the mutual and relative oscillations of the gyroscopes are damped by means of unequal couples on the gyroscopes produced by power taken from one or other of the rotors and controlled by their relative motions. The general construction of the compass may be as described in Specification 16098/15, as shown in Fig. 2, and may comprise a gyroscope in a casing 2 mounted on horizontal trunnions 3 in a frame 1, and a gyroscope in a casing 4 mounted on horizontal trunnions 6 in a ring 5 carried by trunnions 7 in the frame 1. The gyroscopes are thus capable of relative movements in altitude and azimuth, the movements being limited by means of a ring 9 which is mounted on trunnions 10 in the frame 1, is linked to move in altitude with the gyroscope 2, and has a small hole 15 into which' the spindle 14 of the upper gyroscope projects. Fig. 4 shows in plan one method of carrying the invention into effect. Four holes are provided in the casing 4, and a ring 18 carrying four vanes 20 which may catch portions of the jets of air issuing from the holes is secured to the ring 9. Four extra vanes 22 may be carried on' a spider 21 attached to the casing 4. In a modification, Figs. 6 and 10, the casing 4 is fitted with a vertical nozzle 24 from which air passes to tubes 26, 27 having their outlet ends bent as shown. Relative movement of the gyroscopes in altitude causes the jets issuing from the tubes 26, 27 to be unequal and the consequent production of a couple causing the lower gyroscope to follow the upper one in altitude. A nozzle 25 in one of the trunnions 6, and tubes 29, 30 similar to the tubes 26. 27, cause the lower gyroscope to follow the upper one in azimuth also. The nozzles and tubes may be rearranged so that the lower gyroscope follows the upper one in altitude, and the upper one follows the lower one in azimuth, or vice versa. In a further modification, Fig. 8, the nozzles 24. 25 are secured to divided tubes 31. 32 and 33, 34 respectively, which are bent as shown, so that, when relative displacements occur between the gyroscopes, jets of air impinge on one or more of the vanes 35. 36, 37, 38 and produce couples which cause the lower gyroscope to follow the upper one. Specification 100,490 also is referred to.

Abstract: 382,907. Organs. COMPTON, J. H., Chase Road, Willesden, London. May 27, 1932, No. 15147. [Class 88 (ii).] Relates to organs of the kinds wherein a single flue-pipe yields two or more notes, or one note in two or more degrees of loudness. To equalize the quality and the strength or the pitch, the area of the mouth of the pipe is varied automatically in accordance with the wind pressure applied. In Fig. 1 a motor G, spring-loaded at H and connected by a tube U to the throat C, controls a slide J and a pivoted beard L. The requisite wind pressures applied to the throat C through the valves B, F, O, when sounding the different notes produced by the pipe with and without the pallets P, Q in operation, control the position of the slide J and equalize the quality and strength. When the pipe is adapted to sound the same note but with different strengths by changing the valves B, F, O operated, the slide J moves to maintain the quality, and the pitch is corrected by the beard L. In the construction shown in Fig. 2, wherein also a beard L is provided if the pipe is to sound the same note in different strengths, normal pressure is applied to the throat C through valve W, increased pressures being obtained through additional valves W<1>, W2 with restricted openings Y<1>, Y<2>, these valves operating motors G<1>, G<2> which by means of stops V<1>, V<2> independently actuate the slide J to different predetermined extents.
