Title: Process for the production of hydrogen from sulphur-bearing carbonaceous fuel
IPC: C01B3/02
Filed: 1969-10-31
Abstract: 1,240,915. Hydrogen. BLACK SIVALLS & BRYSON Inc. 31 Oct., 1969 [1 Nov., 1968], No. 53597/69. Addition to 1,225,206. Heading C1A. [Also in Division C7] Hydrogen is generated from a sulphur bearing carbonaceous fuel by reacting the fuel with oxygen and steam beneath the surface of a molten iron bath to form hydrogen and other gases, introducing brine (as defined in the Specification) on the surface of the molten iron bath so that slag and calcium sulphide are formed, removing slag and calcium sulphide from the molten iron bath, removing hydrogen and other gases from the molten iron bath and separating the hydrogen from the other gases. The hydrogen may be separated by dehydration, adsorption and cryogenic fractionation. The calcium sulphide contained in the slag removed from the bath may be converted into elemental sulphur by granulating and then treating with steam and air or alternatively with carbon dioxide to form hydrogen sulphide which is then converted to sulphur. The steam for the process may be obtained by heat exchange of the offgases with water. The fuel may be crushed coal, pyritic refuse, lignite or peat. " Lime " is defined as CaO, CaCO 3 , CaO/MgO, or CaCO 3 / MgCO 3 .

Title: Pulse generator

Filed: 1971-11-19
Abstract: 1368614 Permanent magnet generators J R WIEGAND and M VELINSKY 19 Nov 1971 [19 Nov 1970] 53865/71 Heading H2A A pulse generator comprises a wire 20 having two layers of different magnetic properties, the two layers initially being magnetized in the same direction, the direction of magnetization of one layer then being reversed, this latter change producing a pulse in a sensor. The rotary pulse generator disclosed comprises a rotatable plastics support 13 having on its periphery a plurality of equally spaced wires 20, each wire having a core of coercivity and retentivity lower than those of an outer shell portion. A stator unit 40 comprises a coil 54 mounted on a magnetic core 46 disposed between two permanent magnets 60, 62 which are arranged to produce magnetic fields of opposite polarity on opposite circumferential sides of the core. When each wire enters one field its core and shell are magnetized in the same direction and when the wire leaves that field, the shell remains permanently magnetized and uses the core as a flux return path, this change in direction of magnetization of the core producing a flux change in the magnetic core 46 which produces a pulse in coil 54. The other of the two magnetic fields adjacent the core 46 is effective for the other direction of rotation of support 13. The shells of the wires may additionally be premagnetized by a permanent magnet 80 or 82 (depending on the direction of rotation of the support).

In the arrangement shown the need for regulation is detected by a sensor 36 in the outflow line 17 from the sump. The sensor acts to partially close dampers 19m in the duct outlet and at a predetermined closure (e.g. from 50 to 80%) a switch 29 is actuated to open the valve 31 located in by-pass 32 so allowing some of the water from pump 33 to be recirculated through the by-pass. Hence, the water supply to the sprays is reduced and as a consequence the injected air flow is also reduced. In a further arrangement (Fig. 2) there are no adjustable dampers at the duct outlet and regulation of the spray head water supply is by a valve (45) in the line 13, said valve being actuated directly by the sensor 36. 34 is a heat load which may comprise, e.g. a cooling tower or a surface condenser.

The insulated conductor or conductors may be the centre core of the rope; the centre core of at least one strand of the rope; or be located in the outer valleys between strands. In the latter instance the rope may be stress relieved before the insulated conductors are placed in the valleys. If the rope is sheathed in insulating material the melting point of the insulating material around the conductor or conductors should be greater than the melting point of the insulating material of the sheath. When the sheath is included before the cable is stress relieved it is of a kind that will retain some plasticity when subjected to the stress relieving temperatures, for example radiation cross linked polyolefin; tetra fluoro ethylene; fluorinated ethylene propylene; and cross linked poly vinylidene fluoride.
