Title: Improvements in or relating to nuclear reactors
IPC: G21C3/04
Filed: 1956-07-16
Abstract: 788,284. Nuclear reactors. STICHTING REACTOR CENTRUM NEDERLAND. July 16, 1956 [July 18, 1955], No. 21932/56. Class 39(4). In a reactor, the fuel and a heat distributing material, which may be a moderator, are sintered or heated together with an adhesive to form a porous material, which may be formed into granules, Berl saddles, Rashig rings, hollow spheres, blocks, plates, rods or tubes. The cooling fluid may be a gas, oxygen, carbon monoxide, helium, hydrogen or deuterium; a liquid sodium hydroxide or bismuth; or a dispersion of liquid in gas such as heavy water in water vapour. The fuel may be uranium 235, uranium 233 or plutonium, while heat distributing moderating material may be beryllium oxide, beryllium carbide or carbon. Thorium oxalate may be added as a treating material and the concentration of fissile material may decrease from the surface to the inside. Where the heat distributing material is not a moderator it may consist of compounds of bismuth, magnesium, lead, phosphorus, silicon, zirconium, and aluminium and the moderating material may be arranged separately in the form of blocks or plates. A fine control of the reactor may be effected by regulating the pressure of the cooling fluid where the latter has moderating properties. The sintering process may take place under pressure, but for small bodies, an aggregate of heat distributing material is formed by mixing with an adhesive and applying pressure. This is then soaked in a solution of the fissile material for example uranium oxalate and heated, to decompose the oxalate, and then sintered without pressure. The formation of the entectic mixture is facilitated by the addition of bervllium oxalate to the fissile solution. Alternatively, aggregate of carbon particles with an adhesive are formed, soaked in fissile solution, heated in vacuo or in carbon monoxide and then sintered.

Title: Improvements in or relating to the separation of tin from impure lead-antimony alloys
IPC: C22B13/06
Filed: 1935-12-21
Abstract: In a process for separating tin from impure lead-antimony alloys by the addition of an oxidizing agent such as litharge to a molten bath of the alloy, the dry dross formed in this way above the bath and containing tin oxide with some lead and antimony, is treated with a slagging agent such as sand or silicious slag whereby the lead and antimony pass to the bath beneath and a liquid slag is formed containing tin oxide.  The slag may be purified whilst on the bath by treatment by a reducing agent, such as coal or soft iron, whereby any antimony and lead oxides therein are reduced to metal which passes to the bath beneath.  The treatment with an oxidizing agent serves to remove zinc and cadmium.  In an example, a dross containing 17 per cent of antimony, 20 per cent of tin, and the remainder lead and sodium yielded after treatment, an alloy comprising 12 per cent of antimony, 1 per cent of tin, and the balance lead.

Title: Improvements in screw pumps
IPC: F04C2/16
Filed: 1951-09-21
Abstract: 696,732. Meshing-screw pumps. KAPP, B. Sept. 21, 1951 [Sept..21, 1950], No. 22164/51. Class 110(ii) The pump has two or more pairs of screws 3, 4; 31, 41, in one plane, with screw threads of opposite hand, for balancing purposes, the depths of the inter-thread spaces varying along the rotors. One or more screw convolutions are cut off by slide valves 16, 17; 18, 19, these being preferably coupled together by an endless chain 22, mounted on pulleys 23-26, the pairs of valves travelling in opposite directions when an external chain C is moved. The shafts may be adjusted axially. Fig. 1 shows screws having the same thread pitch throughout their lengths, the depths of the inter-thread spaces decreasing from inlets 12 to a central delivery port 44. The pump may be immersed in the fluid being pumped. The pistons 17, 19 act as fluid seals to prevent valves 16, 18 being subjected to axial pressure. Cylinders 14, 15 communicate with the screws through holes 28, 29 and are connected to each other by a duct 31. Fig. 2 shows the valves in such positions that no fluid will be pumped as the pistons 16, 18 do not quite close the last, smallest, screw convolution. Fluid entering the casing 13 will, owing to continuously decreasing inter-thread volume, be progressively forced away through the ducts 27, 28 into the interiors of the cylinders 14, 15, but will flow back out of these to the fluid reservoir without loading the pump. The further the valves 16, 18 are moved from the pump centre, the greater the volume of fluid pumped owing to the increased depths of the convolutions.' In a second arrangement, Fig. 4, the outside diameters of the threads are constant but the bases of the inter-thread spaces lie on cones. The intermediate shafts are inclined to the outer ones, those for rotors 49, 50 being stub shafts, Bevel gears couple pairs of shafts.
