Title: Buoyant electric cable
Inventor: GARSHICK ALFRED
IPC: H01B7/12
Filed: 1964-10-07
Abstract: 1,044,738. Buoyant cables. BOSTON INSULATED WIRE & CABLE CO. Oct. 7, 1964, No. 40829/64. Heading H1A. A cable is made buoyant by the provision of a number of braided openwork sleeves which provide voids to reduce the specific gravity of the cable to less than one. The cable shown comprises two different types of cores. The first has a central copper wire 14, which may be stranded, surrounded by a foamed polyethylene sheath 16 which has a specific gravity of about 0.5. Surrounding this shield is a braided silverplated copper jacket 18. This jacket is encased in flotation sleeves each made of an open construction of braided polyethylene filaments 20, 22. The second type comprises a central stranded polyethylene filament 26 surrounded by cores 24 each comprising a wire with an extruded polyethylene jacket. Over all the cores is a wrapping of aluminium-backed plastic tape 30 the metallic side facing outwardly and in contact with it an openwork metal braid 32, the two forming a screening layer. Next follow four flotation layers, each of openwork polyethylene braiding, a layer of tape of polyethylene terephthalate and a waterproof buoyant jacket 42 which is made of rubber. Layer 40 acts to separate the braiding from the rubber in case of incompatibility. The cable is completed by an armouring sheath of flat stainless steel strip and an outer flotation jacket of foamed polyethylene 46.

Title: Process and equipment for producing triethyl aluminium
Inventor: SIMON ATUR
IPC: C07F5/06
Filed: 1962-10-29
Abstract: Pure triethyl aluminium is produced from pure ethyl aluminium sesquichloride by reacting firstly with triethyl aluminium in the absence of any solvent to yield pure diethyl aluminium chloride and then reacting this with molten sodium.  Molten sodium may be added in the form of fine drops to the diethyl aluminium chloride or the diethyl aluminium chloride may be added to the molten sodium. A portion of the triethyl aluminium produced is recycled to the start of the process, which may be continuous. Solvents are not used in the process.

In a steam generator comprising an upright furnace chamber 1 and a lateral gas pass 5 containing superheating surfaces extending rearwardly from the top of the chamber to parallel downpasses 7, 8, respectively, containing superheating and reheating surfaces, the downpasses terminate in a gas turning space 12 from which branch two auxiliary downpasses 14, 15 each containing economizers 31 and respective air heaters 16A, 16B and flanking a space at the rear of the furnace chamber, the space housing the ducting for combustion air for fluent fuel burners 78 disposed in the rear wall of the furnace. Two fans 84 disposed at either side of the furnace chamber supply air through ducts 86 to the heaters 16A, 16B and thence to a tapered distribution duct 88. A pressure equalizing duct 87 connects the two ducts 86. Six fans 96 draw controlled quantities of heated air from the distribution duct 88 via ducts 93, 94 and cold air from the pressure-equalizing duct 87 and discharge the mixed air through ducts 99 to six pulverizing mills 82. The mills 82 receive fuel from a hopper, 83, and discharge through pipes 81 to four rows of nine fuel burners 78 disposed in the rear wall 3 of the furnace chamber. Secondary air for the burners is drawn from the tapered duct 88 through three upright ducts 105, each of which branches into three ducts 102, 104, 103, which supply burners in the upper, middle two and lower rows respectively. The waste gases from the unit are led through ducting 91 to a chimney, not shown.

Each group of leaf springs comprises four in the embodiment shown, each pair 4, 5 and 6, 7 engaging in a respective axial groove 9, 10 of hub 11 with clearance to permit a restricted passage of damping fluid. In alternative embodiments there may be six springs per group, in two groups of three (Fig. 4, not shown) or spaces may be arranged between springs 4 and 7 and elements 12 which separate the groups, to increase the degree of torsional movement possible (Fig. 3, not shown) or two pairs of springs of different thicknesses may be provided, with the thinner springs acting before the thicker springs due to clearance provided between the thinner ends of the thicker springs and the edges of the axial groove in the hub 11 which receives them.

Abstract: 1447546 Pyrolysis of carbonaceous materials OCCIDENTAL PETROLEUM CORP 14 Sept 1973 [28 Sept 1972] 43380/73 Heading C5E Particulate carbonaceous material 10 is passed through a first pyrolysis zone 22 in a turbulent stream of conveying gas 18 and heated, e.g. at 675-900‹ C. for 0À01-3 seconds by a particulate solid heat carrier to produce a gaseous pyrolysis product which contains C 1-4  hydrocarbons, the pyrolysis products are cooled at 26 to prevent appreciable thermal decomposition of the gaseous hydrocarbons, separated at 27 into gaseous products 28 and solids 34, the solids 34 are introduced into a second pyrolysis zone 38 in a turbulent stream of conveying gas and heated, e.g. to 760-980‹ C., by a particulate solid heat carrier to generate carbon monoxide and hydrogen. A portion of the CO + H 2  product of the second zone can be recycled to the two zones 22 and 38 as the hot conveying gas. As shown, in the treatment of a bituminous coal 10, steam 21 and 47 can be introduced into the pyrolysis reactors 22 and 38 and a portion 62 of the solid product 52 from the zone 38 is subjected to partial combustion at 68 to produce hot char which is recycled as the stream 76 to the pyrolysis reactors. Liquids 80 are separated from the gaseous products 32 and 56 from the two pyrolysis reactors and recycled as the stream 88, after removal of thermally stable components 86, e.g. benzene. The gas 82 is combined with a CO 2 +CO+H 2  stream 120 produced by reacting hot char with hot steam in the synthesis vessel 116, e.g. 815-1370‹ C. and 300-600 p.s.i.g. The combined stream is hydrogenated at 94 at 315-510‹ C. and 50-150 p.s.i.g. using a cobalt molybdate catalyst to react propylene, ethylene and butylene with hydrogen contained in the stream. The hydrogenated gas is subjected to a shift reaction at 96 at 315-510‹ C. and 50-100 p.s.i.g. using a chromium-promoted iron oxide catalyst. H 2 S and CO 2  are removed at 104 and 106 and any hydrocarbons having 5 or more carbon atoms are removed by adsorption with activated carbon at 110. The gas is then heated at 112 to 260-480‹ C. and subjected to methanation at 128 to convert carbon monoxide to methane and steam using a nickel catalyst such as Raney nickel. Water is removed from the gas at 140 after cooling at 136 to 27-50‹ C. and compression at 138 to 900-1100 p.s.i.g. The product gas 134 is interchangeable with natural gas and typically contains 95% by volume of methane, 3À7% ethane and 1À3% hydrogen.

A fluid-cooled terminal for a cable in which the conductors are disposed in two groups of different polarities has an elastically yieldable sealing element 7 formed as an extension of the insulator 3 separating the groups of conductors and either integral with it or glued to it. The sealing element 7 is provided with openings 23, 24 into which rigid spacer members 21, 22 are inserted, such that when the terminal halves are tightened together the thickness of members 21, 22 which is less than that of element 7 limits the amount by which the latter can be compressed. The terminal is in two semicylindrical parts 6, with flattened ends, the sealing element 7 being disposed between the plane faces of the two parts, the parts and cable being cooled by fluid which is admitted via orifice 10 to channels 13, 13a, 12, and thence to the cable. The outer insulating sheath of the cable (17, Fig. 1) is a force-fit over the assembled terminal and is held tight by a clamping collar (not shown) and grooves 18 on the outer face of the terminal. An alternative form of seal has a plate (15, Fig. 3) of rigid insulating material whose thickness is locally reduced wherever sealing element (26, Fig. 3) is bonded to it, so that plate (25) limits the amount by which sealing element 26 can be compressed.
