Abstract: 1498318 Gasification of carbon- and/or hydrocarbon-containing substances EISENWERK GES MAXIMILIANSHUTTE mbH 7 May 1976 [9 May 1975 10 May 1975 (3) 4 Feb 1976] 18728/76 Heading C5E Solid and/or liquid carbon-containing and/or hydrocarbon-containing substances are continuously gasified in a bath of molten iron in a refractory-lined reaction vessel, by passing them together with oxygen or a free-oxygen-containing gas into the bath through one or more nozzles which are mounted in the refractory lining of the vessel below the surface level of the bath, and which thereby wear away at an equal rate with the lining. Fig. 7 shows a suitable reaction vessel in combination with an installation for desulphurizing the slag formed during the process. Vessel 21 contains molten iron 22 through which is passed via nozzle 23 most preferably oxygen and particulate coal. The slag 24 that is formed flows through an outlet passage 25 in which is incorporated a settling chamber 26 for separating out droplets of iron, into the desulphurizing vessel 27. The iron flows back into vessel 21 through a passage 28. Oxygen or oxygen-containing medium is fed into vessel 27 through a nozzle 29 to convert the sulphur in the slag to sulphur dioxide, which is removed. By means of gas lift 30, the slag is pushed back to the main vessel 21 through a passage. A proportion of the slag can be continuously withdrawn from the circuit. The gas obtained consists largely of carbon monoxide and hydrogen and may be used as reduction gas for metallurgical purposes.

Title: Circuit changing arrangements and fuses incorporating such arrangements

Filed: 1966-04-29
Abstract: 1533971 Setting fuzes DEFENCE SECRETARY OF STATE FOR 27 April 1967 [29 April 1966] 19070/66 Heading F3A In an electrical fuze for a shell, rocket or missile, the igniter is operated by output voltage from a circuit adjusted in a predetermined manner. The circuit parameters are selected to the present required output voltage, by means of a network of electrical fuzes which are selectively blown. The required fuzes are blown prior to firing the shell, but the circuit is sensitive only following the action of an inertia switch operated after firing the shell. In one embodiment, the resistance network, which controls an amplifier in a proximity fuze, is short-circuited by parallel connected electric fuzes which are selectively blown by the application of preparatory signal voltages. The preparatory circuit is subsequently broken, and the fuze armed, by an inertia switch. In a second embodiment, a capacitive network is provided with series electric fuzes which are selectively broken, as in the first embodiment, so as to vary the circuit time constant, and hence the fuze timing delay. A third embodiment comprises a clock fuze timing selector. The selector contacts required to operate the igniter, and specified time after firing are released by operation of a fused network prior to firing. After firing, both inertial and centrifugal forces arm the fuze and release the clock mechanism.
