Abstract: 958,650. Moderator structures. HEAD WRIGHTSON & CO. Ltd. Aug. 29, 1960 [Aug. 29, 1959], No. 29521/59. Heading G6C. A nuclear reactor core structure is built of graphite blocks mounted vertically end-to-end in columns and having axial coolant channels, and tiles arranged in layers between the adjacent blocks in each column, the tiles in each layer being of two thicknesses, one set of tiles being double the thickness of the other, the tiles of double thickness being arranged with their axes of extrusion extending in a vertical direction while the tiles of single thickness are arranged in superimposed pairs to alternate with the tiles of double thickness in each layer, the tiles of each pair being set with their axes of extrusion horizontal and at right angles to one another, each tile of the pair being of reduced length perpendicular to the axis of extrusion as compared with its length parallel to this axis. As shown in Fig. 5, pairs of single thickness tiles 5, 6 placed (and keyed) one on top of the other with their axes of extrusion mutually at right angles alternate with double thickness tiles 7. As a consequence of their rectangular shape, the tiles 5, 6 contact adjacent tiles 7 on two opposing sides only. The result of the above tile arrangement is to minimise the effects of Wigner growth and shrinkage, or shrinkage alone. The manner in which the graphite blocks A and the tiles 5, 6 and 7 are keyed together is seen from Fig. 7.

Title: Utilization of proton recoil energy in neutron irradiated vapour phase organic reactions
IPC: C08F10/00
Filed: 1959-09-02
Abstract: <FORM:0883768/IV (b)/1> The conversion of organic compounds in the vapour phase is effected by passing the vapours through a reaction zone containing fibres or strips of hydrogen-yielding material which have at least one dimension not greater than 20 microns and which on bombardment with fast neutrons yield recoil protons and irradiating the zone with fast neutrons having an average energy above 100 e.v.; energy is imparted to the reactants by recoil protons from the fibrous material.  The conversion is preferably effected inside a nuclear reactor which may contain fixed fuel elements 2, preferably solid though they may be liquid or gaseous, cooled by a liquid coolant entering through pipe 3 and leaving by pipe 4 or may be of the type in which the fissile material is suspended or dissolved in the coolant, e.g. liquid bismuth or water containing dissolved uranium or systems based on molten fluorides.  Uranium 235 and 233 and plutonium 239 may be used as the fissible material as the element or as compounds or alloys and may incorporate elements of the same atomic number and moderators such as carbon, beryllium or ordinary or heavy water.  Liquid sodium is the preferred coolant, and heat is extracted in an external heat exchanger, water, biphenyl, terphenyl or fused salts may also be used. Conversion zone 5 is filled with fibres having a diameter of 0.5-20 microns and made of organic polymers such as polyethylene of molecular weight 10,000-200,000, nylon, polyisobutylene or polystyrene which may be cross-linked or of inorganic hydrides such as lithium-7 hydride.  The fibres have a true density of 0.5-2 gm/cc., a hydrogen nuclei to other nuclei ratio greater than 0.9 and occupy 1%-80% of the volume of the conversion zone so that the average density is 0.005-1.6 gm/cc.  The conversion zone 5 acts as a moderator and, maintaining a flux of 109 to 1016 neutrons per cm2/sec., may contain an average 1020-1023 nuclei per cc.  The material for conversion enters by pipe 6 and leaves by pipe 7.  Conversions referred to are isomerisation of paraffins, alkylation of paraffins with olefins, hydrogenation, cracking and polymerisation such as the conversion of cetane to lubricating oil at 100 DEG F.-900 DEG F. and 1-1,000 p.s.i. which latter reaction is exemplified.

Title: Process for the preparation of aromatic isothiocyanates
IPC: C07C331/28
Filed: 1937-11-02
Abstract: Aromatic isothiocyanates are prepared by reacting dithiocarbamates with heavy metal salts, characterized in that the reaction mixture is treated with an oxidizing agent before, during or after the reaction. If the reaction is conducted in this manner it is stated that the expensive heavy metals such as lead and copper may be effectively replaced by inexpensive heavy metals particularly iron.  In examples: (1) commercial alpha-naphthylamine, carbon disulphide and ammonia are reacted and an aqueous suspension of the product treated with a solution of lead nitrate in the presence of chalk.  The filtered product is crumbled and exposed to air oxidation for a considerable time before being extracted with acetone to give an 80 per cent yield of isothiocyanate; (2) alpha-naphthylamine, carbon disulphide and ammonia are reacted as in example (1) and the product treated with an aqueous solution of ferric chloride.  Extraction of the precipitate with acetone gives a high yield of isothiocyanate; (3) p-phenylenediamine, carbon disulphide and ammonia are reacted and the product treated with a solution of ferrous sulphate and sodium carbonate.  The precipitate is dried and air oxidized before extraction with acetone; (4) the dithiocarbamate prepared in example (3) is oxidized by treatment with hydrogen peroxide; (5) the dithiocarbamate prepared as in example (3) is treated with ferric chloride and the precipitate extracted with acetone.  The residue from the reaction filtrate contains the iron in the divalent form, and this after treatment with chlorine may be used again; (6) as in example (5) using a slightly smaller amount of ferric chloride; (7) aniline, carbon disulphide and ammonia are reacted and the dithiocarbamate oxidized with ferric chloride. The phenyl isothiocyanate is purified by extraction with ether and steam distillation; (8) the dithiocarbamate prepared as in example (7) is treated with ferric chloride and then with hydrogen peroxide and the product purified by steam distillation; (9) the same as example (8) using a slightly modified procedure.
