Patent GB-1032747-A (GB)
Title: Manufacture of ferro-silicon
Inventor: ROBIETTE ALFRED GORDON EVANS
IPC: C22C32/00
Filed: 1962-05-21
Abstract: Ferro-silicon e.g. containing 14 to 95% Si is made by pelletizing or briquetting a finely divided mixture of coking coal with iron ore and silica, and coking or carbonising the pellets or briquettes partially or completely to produce a cellular coked structure holding the components of the charge together e.g. interstitial partially reduced finely divided iron ore containing silica, until final reduction to Fe-Si in an electric smelting furnace. Preferably only water is used as a binder for the pellets (or briquettes) but binding agents such as bentonite, sulphite lye or starch may be added to increase the strength of the "green" pellets. Also anthracite, charcoal or coke may be included, and the total amount of carbon may be in excess to provide the requisite amount in the final alloy.  The iron ore may be partially replaced by comminuted steel or iron or other forms of iron oxide such as rolling mill scale, and the silica may be in the form of tailings from dressed siliceous iron ores or sand. The pellets may be dried e.g. at 100-300 DEG C. before the coking or carbonising step, which may be performed at 800-1300 DEG C. either within the smelting furnace or outside, e.g. on a grate or in a charging hopper, using the heat provided by combustion of at least part of the combustible gas (mainly CO) produced in the final reduction and/or of part of the coal in the pellets and/or of volatiles produced in the step.ALSO:Ferro-silicon, e.g. containing 14 to 95% Si, is made by pelletizing or briquetting a finely-divided mixture of coking coal with iron ore and silica, and coking or carbonizing the pellets or briquettes partially or completely to produce a cellular coked structure holding the components of the charge together, e.g. interstitial partially reduced finely divided iron ore containing silica, until final reduction to Fe-Si in an electric smelting furnace.

Title: Improvements relating to tubular nuclear fuel rods
Inventor: SWANSON KENNETH MACGREGOR
IPC: G21C3/10
Filed: 1965-05-11
Abstract: 1,135,235. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 4 May, 1966 [11 May, 1965], No. 19913/65. Heading G6C. A tubular nuclear fuel rod has inner and outer sheaths, one of which has a termination free to move axially of the other and defining with it a clearance through which fission product gases can be vented, the sheaths being rigidly fixed together only in the region of the rod remote from the termination so as to allow differential thermal expansion of the sheaths in the axial direction of the rod. In the embodiment shown in Fig. 1, a fuel rod has stainless steel inner and outer sheaths 11, 12, the annular space between which contains pellets 13 of breeder fuel at the upper and lower ends and a length of particulate enriched fissile fuel 14 extending between the breeder sections. The fissile fuel 14 is a ceramic, e.g. a mixture of UO 2  and PuO 2 . The breeder sections and the particulate fuel length are separated by molybdenum end spacers 15 brazed to the inner sheath 11 but slidably engaged with the outer sheath 12. A top end cap 18 at the upper end of the outer sheath 12 connects the sheath to a stainless steel tubular extension piece 19 which embraces the inner 11 whilst leaving a small vent clearance 20. Interposed between the top breeder section and the top end cap 18 is a stainless steel knitmesh filter 22. A terminal portion of the inner sheath 11 protruding beyond the extension piece 19 has a hood attached to it which enshrouds the extension piece like a skirt and at its lower end carries a fitting 25 which engages the extension piece at circumferentially equispaced locations. The spaces between these locations provide openings for coolant entry. The length of the hood is such that the distance between the above openings and the top of the extension piece 19 gives, when taken in conjunction with the radial spacing of the hood from the extension piece, a sufficient volume to ensure that the coolant in the hood does not enter the clearance 20. A cluster of such fuel rods may be tightly packed on a triangular lattice within a stainless steel hexagonal wrapper having a bottom fitting with spaced cylindrical bearing surfaces for fitting into a socket of a core support structure of a reactor, e.g. a sodium cooled fast reactor. A stainless steel knitmesh filter between the bearing surfaces enables coolant from an inlet plenum in the core support structure to enter the wrapper. A wire 36 wrapped in a helix around each of the fuel rods maintains the spacing in the cluster. The helix has a long pitch so that the spacer wires of adjacent rods abut the opposite outer sheaths. The fuel rods are supported only at their lower ends by means of parallel bars which pass through slots 38 in locating tubes 17 secured to the lower ends of the fuel rods. The bars are in turn carried by a ring which is riveted to the wrapper.

Filed: 1950-08-11
Abstract: Aromatic hydrocarbon radicals are introduced into an alkyl-polysiloxane by heating the siloxane with sodium, magnesium or an alloy of sodium and magnesium, and with an aromatic halogeno-hydrocarbon, and separating the substituted polysiloxane so produced.  The reaction is preferably effected in the presence of a diluent, e.g. dibutyl ether or xylene, and at a temperature from 80 DEG  to 250 DEG  C.  The reaction with magnesium may be activated by the addition of iodine and/or bromobenzene.  In examples (1) dimethylpolysiloxane is heated under pressure with chlorobenzene, magnesium and dibutyl ether, iodine and bromobenzene being used as catalysts.  The reaction product is treated with hydrochloric acid and the non-aqueous layer fractionated; (2) a mixture of chlorobenzene, sodium, dimethylpolysiloxane and xylene is heated under atmospheric pressure, with subsequent separation of the substituted polysiloxane as in (1).  Other aromatic halogeno hydrocarbons specified are dichlorobenzene and chloronaphthalene. The compounds are suitable as oils in vacuum technology.
