Title: Coal gasification plant gas for iron ore reduction - is divided into partial reducing, heating and sulphur-generating streams
Inventor: HEINRICH PETER DR
IPC: C21B13/00
Filed: 1979-02-23
Abstract: Ores, esp. Fe ores, are reduced directly with coal gasification plant gases worked up by a low temp. treatment. Novelty consists in dividing the crude gas into 3 partial streams by low temp. treatment and fractional distn. The streams consist of (a) a partial stream (A) contg. H2/N2/CO/A, which is subsequently mixed with recycle gas (K), heated and used as reducing gas; (b) a partial stream (B) contg. CH4/C2H4/CO2/C2H6, used for heating partial stream (A) and a recycle gas (K) to reducing temp.; and (c) an H2S- and COS-contg. partial stream (C). (C) is further worked outside to elementary S, but small measured (C) quantities can be admixed to partial streams (A) and/or (K) before heating, to avoid soot formation. Division into streams (A,B,C) presents no difficulties, because the 3 gas gps. condense at different temps. at a given pressure, e.g. H2/N2/CO/A at 30-118 degrees K, CH4/C2H4/CO2/C2H6 at 164-242 degrees K and H2S/COS at 272-292 degrees K, at 10 bar. (ii) Fe sulphurisation during redn. is prevented.

Title: Magnetic coupling for rotating shafts - with shaft axes at right angles or other large angle and disc with segments arranged in concentric rings
Inventor: IWATA SEIICHI
IPC: H02K49/10
Filed: 1979-11-16
Abstract: The magnetic coupling employs a permanent magnet disc on both the driving and driven shafts. Each disc (1, 2) has a number of magnets arranged in alternating polarity. A small gap separates the discs. Typically the input and output shafts are at 90 deg. but any other angular relationship can be used without the need for elaborate and accurate machining of the parts. The driving disc (1) may have the magnet segments arranged in a series of concentric rings (5, 6, 7, 8) and the driven disc (2) on a sliding shaft. Then, depending upon the position of the driven disc relative to the driving magnet rings the transmitted torque can be varied although the speed is fixed by the number of poles. Alternatively the magnetic ring arrangement may be on the driven shaft.
