Abstract: 541,414. Synthetic resin compositions moulding. CELLOMOLD., Ltd., DAVIES, D. N., and READ, L. M. May 22, 1940, No. 9073. [Class 2 (iii)] [Also in Group V] A composition of matter comprises a mass of loose substantially dry particles, so that the mass can be conveniently handed and distributed in a mould, and consists mainly of an intimate mixture of a heat hardenable phenolicaldehyde resin with wood sawdust in proportions within the limits 5 to 25 per cent. by weight of resin and 65 to 90 per cent. sawdust, the resin and sawdust amounting to at least 90 per cent. in the absence of any appreciable quantity of water or any more highly volatile substances other than such as may comprise a natural part of the resin or sawdust, the sawdust being in normal substantially non-pulverized condition and having a water content below 35 per cent. The resin may be obtained by condensing cresol, resorcinol or other phenol with formaldehyde or other aldehyde, and may be a solid resol or a novolak; if a novolak is used, hexamethylene tetramine or other appropriate hardening agent is incorporated in the composition ; fillers, lubricants, plasticizers, colouring matter, and oxides of alkaline earth metals, e.g. magnesia or lime, may be incorporated in the composition. The resin, either dry or in solution in a volatile solvent, is compounded with the other ingredients in a mixing machine which kneads but does not disintegrate the sawdust particles. In examples, a cresol-formaldehyde resol, sawdust, magnesia and a lubricant, e.g. olein, are mixed either in a heated Banbury mixer or in a cold ball mill, or a solution of the resol in a volatile solvent, e.g. methylated spirit, is mixed with the other ingredients either in a hot jacketed blade mixer, so that the volatile solvent is removed during mixing, or in a cold blade mixer of the Baker Perkins type, the mixture being then poured into a container and dried in an oven to remove the volatile solvent. The compositions have low flow properties, and can be moulded into sheets, blocks or similar articles of simple shapes in heated platen presses under a pressure of less than 600 lbs. sq. inch the product being removable from the mould whilst hot without blistering. A press comprising platens 3, 4, 5 connected by slotted links 6 may be employed, the composition being placed in a framework 8 of highly compressible material, e.g. strips of fibrous board having a base of sugar cane fibre, the strips being pinned together if desired. The composition and the framework are then compressed by applying a pressure of say 300 lbs. sq. inch hydraulically to the bottom platen 5, heat being applied simultaneously to cure the resin.

Title: Catalytic oxidation of ammonia
IPC: C01B21/26
Filed: 1930-03-22
Abstract: The catalytic oxidation of ammonia to oxides of nitrogen is effected in the presence of a siliceous or non-siliceous base-exchange body, which has been leached with dilute acid to remove part or all of the exchangeable and non-exchangeable basic constituents, and with which a catalytically active component is either chemically combined in exchangeable or non-exchangeable form or is physically associated in the form of a diluent.  The base-exchange bodies may be coated on to massive carriers or admixed with diluents.  Stabilizers, consisting of compounds of alkali or alkaline-earth metals, and stabilizer promoters, which possess catalytic activity but are not specific catalysts for the reaction in question, may be added.  These stabilizer promoters may be catalysts which favour dehydration, or the oxidation of organic impurities, either to unobjectionable substances or to compounds which are easily separated from the final product. Details of the preparation of the base-exchange bodies are similar to those described in Specifications 279,466 and 281,307, [both in Class 1 (i), Chemical processes &c.].  Temperatures of 500 DEG -800 DEG  C. may be employed, and the reaction may be carried out at atmospheric, increased or reduced pressure.

Heading G6C In nuclear fuel elements, cooling of the fuel mass is effected by a coolant fluid which flows along the elements. In certain of the embodiments a proportion of the longitudinal flow is deflected perpendicularly, through orifices, to form small jets. These promote turbulence in the longitudinal flow by producing transverse auxiliary circulating paths which increase the heat transfer from the fuel to the coolant. In other embodiments in which deflecting surfaces promote the auxiliary circulating paths, the surfaces are either separate, inclined, plates mounted across the direction of flow -or are single, helically twisted, surfaces-disposed along the flow axis. The fuel may be in the form of rods, tubes or plates and immersed in the coolant so as to permit the longitudinal and transverse coolant flow over the external surfaces. Each external surface is swept by a number of similar transverse circulating currents. Specification 831,758 is referred to.
