Patent GB-361903-A (GB)
Title: Process of treating materials containing iron in combination with sulphur
IPC: C22B1/08
Filed: 1930-05-22
Abstract: <PICT:0361903/III/1> Materials containing iron in combination with sulphur are treated in a finely divided condition with dilute chlorinating gases to form ferrous chloride, liberated sulphur is removed as vapour substantially free from heavy metal chlorides, the ferrous chloride formed is oxidized with preheated air with formation of ferric chloride diluted with nitrogen which is returned to the chlorination step, and the chlorinating and oxidizing reactions are carried out at such temperatures that no bulk fusion of the solids present takes place.  The material to be chlorinated may be supplied in a finely divided state, or be brought into such state during the treatment, for instance by effecting the reaction in a drum loosely filled with pebbles or balls, such as that described in Specification 348,651; preferably also the material is moved countercurrent to the heated chlorinating gases.  The chlorinating and oxidizing reactions may be carried out in separate kilns, or as shown in Fig. 1, ore preheated to 300-350 DEG  C. may be fed in at X to a single kiln and dry air and chlorine, preheated say to 300-350 DEG  C. be supplied at Y.  After passing a preheating zone A, the ore is chlorinated by residual chlorine (sulphur chloride) in the zone B1, and by ferric chloride coming from zone C in zone B2. Sulphur free from heavy metal chlorides, but containing possibly arsenic, antimony, and bismuth chlorides, and nitrogen from the air, exits at X.  In zone C ferrous chloride formed in zone B2 is oxidized by the air in the gases to ferric chloride and oxide, the former passing to zone B2 and the latter being discharged with gangue and unaltered chlorides such as those of copper, nickel, zinc, and lead at Y.  Manganese if present is discharged as oxide. The kiln is jacketed to ensure uniform temperatures, and with preheated ore and gases external heating is unnecessary.  The permissible temperatures are such that no ferric chloride appears in the gangue, and no substantial amount of ferrous chloride is included in fused chlorides of other metals present.  In zone C a temperature of 280 DEG  C. is necessary to volatilize all ferric chloride, and in zones B2, B1 ferric chloride and sulphur must remain in the vapour state.  Make-up chlorine may be introduced as chlorine, sulphur chloride, or ferric chloride, but when copper, nickel, or cobalt are present, the presence of free chlorine in the oxidizing zone is advantageous as it protects their chlorides from oxidation.  When a separate kiln is used for the oxidation step, chlorine is mixed with the heated air for oxidation, and the ferric chloride vapours together with make-up chlorine, if necessary, are passed into the chlorinating kiln.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter:--the air for oxidation is not necessarily preheated, nor is the sulphide material necessarily finely ground.  This subject-matter does not appear in the Specification as accepted.

Filed: 1964-04-16
Abstract: 1,023,978. Arresting aircraft. AMERICAN ENGINEERING CO. April 16, 1964, No. 15779/64. Heading B7G. [Also in Division F2] In an aircraft arresting installation comprising a cable 14 extending across a runway A and connected at its ends to tapes 10 wound in a single flat spiral on each of two drums 61 of respective energy absorbers B, C which are braked hydrodynamically, the tapes 10 are of varying thickness such that the radius arm at the point of unwinding of the tapes reduces in accordance with a predetermined programme to suit the landing speed and weight of a particular aircraft, whereby on selection of an appropriate pair of tapes any aircraft whose arrester hook engages the cable 14 may be brought to rest in a given distance with approximately constant deceleration, i.e. the tape tension is substantially constant since as the aircraft speed decreases so does the radius arm and the rotational speed of the drums is controlled accordingly. The energy absorbers are offset so that the drums are unwound in the same direction. Each drum 61 comprises upper and lower discs 64, 65 and is keyed to a hub portion 57 of a shaft 42 carrying a rotor 43. Blades 44, 45 on the rotor co-operate with stator blades 25, 35 in a easing 23 filled with liquid, e.g. water or antifreeze solution, to cause hydrodynamic braking of the shaft. The numbers of rotor and stator blades are different to prevent heating. The liquid is cooled by passing via an outlet 68 and pipe 70 (Fig. 4, not shown), to a heat exchanger containing a pump and thence via pipe 71 back to the casing 23. The pump is driven only during rewind of the tape which is effected by an I.C. engine D driving the pump and, via a disconnectible clutch 82 and gear-box 83, a drive sprocket 85 connected by a chain 86 to a sprocket 87 secured to the drum disc 65. The tape is detachable from the drum 61 for replacement by a differently programmed tape by removal of pins 62a securing a looped end portion of the tape together with a core 62. When the tape is being rewound a sector-shaped guide member 75 is mounted in the position shown to guide the tape. Also a friction member (Fig. 9, not shown), is pressed against the edge of disc 65 to prevent unwinding when clutch 82 is disengaged after rewinding, thus establishing a desired pretensioning of the cable 14. In a modified embodiment (Fig. 11, not shown), the drum is mounted on a horizontal axis in a concrete box 91 disposed below ground and the tape is guided by a rub block 95 on an arcuate front wall 93 (Fig. 13, not shown). The drum is enabled to swing in a horizontal plane by mounting the energy absorber unit on a hinge pin 96. In a modification (Fig. 12, not shown), the rub block 95 is replaced by a roller 107 carried by an arm 106 mounted on the axis of the drum. In a further modification, Fig. 13, the rub block 95 is replaced by a series of rollers 113 mounted at closely spaced points around the wall 93.

Title: Improvements in and relating to the production of aromatic bodies
IPC: C10G35/06
Filed: 1941-04-23
Abstract: Natural petroleum oil fractions of which substantially the whole boils within the range 150-250 DEG  C. are converted into a liquid mixture of aromatic substances by subjecting the starting materials to a heat treatment within the temperature range 500-750 DEG  C. in the presence of a hydrogenation and dehydrogenation catalyst, at a space velocity of 0.1-0.5 litres of starting material per litre active catalyst volume per hour. The preferred catalysts are those selected from the group consisting of chromium, cobalt, copper, iron, manganese, molybdenum, nickel, platinum, palladium, silver, tungsten and vanadium, their mixtures and alloys.  The products consist largely of aromatic hydrocarbon including benzene, toluene, ethyl benzene, styrene or mixtures thereof and xylenes.  Gaseous products are also obtained which contain methane, ethane, propane, butane, ethylene, propylene and butylenes.  The catalyst may either be in compact form or on a carrier such as asbestos, pumice or bentonite. The reaction may be carried out in one pass, or where an incompletely aromatised product is first formed, this may be returned to the system and recirculated.  The aromatised product of boiling range 145-180 DEG  C. obtained according to the invention may be further treated by the same or a different hydrogenation catalyst whereby higher and lower boiling aromatics especially chrysene are obtained. In examples: (1) gasoline of boiling point 150-250 DEG  C. is passed through a steel tube containing as a catalyst a mixture of fine copper and iron turnings in the ratio of 5 : 1.  The products are passed through a tower filled with spindle oil to extract light products and separate them from the non-condensable gases.  The liquid product is fractionated to isolate benzene, toluene, ethylbenzene, higher alkyl benzenes and heavy aromatics.  The alkyl benzene fraction can be separated into isopropyl benzene mesitylene, tert.-butyl benzene, 1 : 2 : 4-trimethylbenzene sec-butyl benzene and indene. This fraction resembles the solvent naphtha from coal tar. This fraction (140-150 DEG  C.) may be subjected to catalytic cracking with the catalysts used in its preparation to give lower aromatics and also naphthalene methyl naphthalenes, ethyl naphthalene, di- and tri-methyl naphthalene, anthracene, 2-methyl-anthracene, 2 : 7-dimethyl anthracene, chrysene, pyrene, di-hydro pyrene and 1 : 2 - (21 : 11 - naphtho) - 7 : 8 - benzophen - anthrene.
