Abstract: 1282204 Reducing lateritic ores INTERNATIONAL NICKEL CO OF CANADA 31 March 1970 [28 March 1969] 15058/70 Heading C7D Lateritic ore containing one or more of Ni, Co and Cu as well as Fe e.g. limonite is selectively reduced in a rotary kiln by passing it countercurrent to reducing gases successively through a pre-heating zone, a strongly reducing zone in which the atmosphere is maintained at a ratio of reducing to oxidizing gases equivalent to a CO:CO 2  volume ratio of at least 1À5:1 by supplying reducing gases thereto through the kiln wall and supplying heat by burning fuel or part of the reducing gases therein, and a moderately reducing zone in which the atmosphere is generated to have a ratio of reducing to oxidizing gases equivalent to a CO:CO 2  volume ratio below 1.5:1 by partially burning fuel at the adjacent discharge end of the kiln, the latter also supplying up to half the total heat required in the kiln; combustion is controlled in both reducing zones to maintain the temperature throughout between 538 and 760C. The balance of the heat required may be provided by burning fuel introduced through the kiln wall. The fuel and reducing gases may be hydrocarbon oil and producer, water or other synthesis gases, or H 2  and CO. Up to 5% powdered coal, for supplying further fuel for combustion in the pre-heating zone, and up to 1% sulphide e.g. pyrites, to catalyse subsequent conversion of Ni to Ni carbonyl, may be mixed with the ore feed. A lateritic ore containing 38-46% Fe, 1-3% Ni and 0À05-0À3% Co, with MgO and SiO 2 , can be so reduced that all the Ni and Co, but e.g. less than 15% of the Fe content, are reduced to metal.

Title: Modulating systems for carrier wave signalling systems
IPC: H03C1/06
Filed: 1935-05-24
Abstract: 440,993. Modulating systems. STANDARD TELEPHONES & CABLES, Ltd., 63, ALDWYCH, London.-(Assignees of Ferrell, E. B. ; P.O. Box 212, Oakhurst, New Jersey, U.S.A.) May 24, 1935, No. 15211. Convention date, June 9, 1934. [Class 40 (v)] Relates to modulating systems in which distortion is reduced as described in Specification 421,013 by deriving a signal-frequency component from the modulated output which is fed back to oppose the modulating signal ; and consists (a) in deriving this signal-frequency componentfrom the plate current of a modulator valve or a subsequent amplifier valve which is biassed back to a point of little or no plate current or (b) in rectifying the modulated output by a pair of diode valves and applying the rectified voltage to the grids of a pair of push-pull signal amplifiers. As shown in Fig. 1, the modulating valve 13 has the carrier source 12 coupled to its grid circuit which also includes one arm A of a bridge circuit 6. The signal voltage from a microphone 4 is applied across one diagonal of the bridge 6, and the other diagonal is occupied by a choke 18 in the plate circuit of the valve 13. The grid is thus influenced both by the original signal voltage and by the distortion-compensating signal voltage arising across the choke 18. In a modification (Fig. 2, not shown), the signal voltage and the compensating-voltage are applied in series to the outer grid of a tetrode modulating-valve which has the carrier applied to its inner grid. In another form (Fig. 3, not. shown), the compensating voltage is derived from the plate circuit of a power amplifier valve and is combined with the original signal voltage by a bridge circuit as in Fig. 1. The combined voltage is, however, amplified by an auxiliary valve before being applied to the modulator. A carrier amplifier preceding the modulator has a choke coil in the cathode lead giving negative feedback for the suppression of accidental noise modulation which may be present at that stage. In Fig. 4, the signal from a microphone 4 is applied to two pushpull amplifiers 23, 24, the output of which is fed from a transformer 27 to the plate circuit of the modulator valve 13, which has the carrier wave from a source 12 applied to its grid. The modulated output passes to the aerial 2 and also energizes a tuned circuit T connected to a pair of diode rectifiers 9, 29, the load circuit of which comprises bridge resistances 25, 26 in the grid circuit of the amplifiers 23, 24; compensating voltage is thus fed back to the signal amplifier.
