Abstract: 1,273,719. Fuel elements. COMBUSTION ENG. Inc. 19 April, 1971 [27 March, 1970], No. 25438/71. Heading G6C. A bimetallic spacer grid 10 comprises an internested series of spacer elements including a first series of primary spacer elements 12 aligned in spaced parallel rows and a second series of primary spacer elements 14 aligned in spaced parallel rows oriented transversely to the rows of spacer elements 12. Parallel to the primary spacer elements 12 and positioned therebetween are a first series of parallel rows of secondary spacer elements 16. Similarly, a second series of secondary spacer elements 18 are oriented transversely to the first series of secondary spacer elements 16, being interspaced between the second series of primary spacer elements 14. A unitary structure is assured by welding the points of intersection of the spacer elements. The spacer elements are formed of a strip of a first material having a low neutron capture cross-section, e.g. zirconium. The depth of the primary spacer elements 12 and 14 is less than one-half, preferably approximately one-third, the depth of the secondary spacer elements 16 and 18. Cut-out openings are provided in the secondary spacer elements to reduce the amount of material and to facilitate the flow of coolant through the grid. The secondary spacer elements have a series of arches 32 and 34 which serve as points of support against which the fuel elements are biased by spring ferrules 20. The latter are retained between transversely oriented spacer elements 12 and 14 by being inserted into slots cut in the spacer elements, and are formed from a second material which has better stress relaxation properties, e.g. Inconel, than the material from which the spacer elements are formed. Each ferrule 20 has an elongated rectangular section body with openings in the sides from which spring members project.

Title: A process for the dehydration of water-containing alkali hydroxides
IPC: C01D1/42
Filed: 1931-09-16
Abstract: Water-containing alkali hydroxides are dehydrated, if desired after partial dehydration by known methods, by treating them in a solid or molten condition or in a non-aqueous solution with quantities of alkali oxide equivalent to the degree of dehydration required.  If complete dehydration is required an excess may be added.  It is also advantageous to add an excess of alkali oxide when the caustic alkali is to be employed in water producing reactions; for example condensation reactions which take place under the influence of caustic alkalis.  According to examples, (1) sodium oxide is added to caustic soda in a solid or molten state; (2) solid caustic soda and sodium oxide are ground together in a closed ball mill; (3) sodium oxide is stirred into molten caustic soda at 350 DEG  C; (4) sodium oxide is added to alcoholic caustic soda at atmospheric or slightly raised temperature.ALSO:Water-containing alkali hydroxides are dehydrated, if desired after partial dehydration by known methods, by treating them in a solid or molten condition or in a non-aqueous solution with quantities of alkali oxide equivalent to the degree of dehydration required.

IPC: B27K3/38
Filed: 1957-08-16
Abstract: 814,584. Treating wood &c. DOW CHEMICAL CO. Aug. 16, 1957, No. 25968/57. Class 140. Wood or other natural or artificially formed lignocellulosic material is dimensionally stabilized by swelling and impregnation with a solution of phthalaldehydic acid or a derivative thereof substituted in the aryl group with at least one chlorine or lower alkyl group, and subsequently curing by heating in an oven or with hot vapours to between 95‹ and 160‹ C. to produce a reaction product between the acid or derivative and the lignocellulose, which remains in the material. The solution used may be of about 20-35 per cent strength and may be in water or an aqueous mixture such as a 50: 50 mixture with propylene glycol methyl ether in an organic solvent such as pyridine or dimethyl formamide which has a swelling action, or in a solvent having little swelling action such as methyl isobutyl ketone, followed by curing treatment with the hot vapour of a swelling liquid, e.g. steam. Impregnation may be effected at normal, reduced, or increased pressure, and at temperatures between 15‹ and 85‹ C. When an aqueous solution is used free water may be removed by heating in a high humidity cabinet or treating with hot inert vapours such as those of xylene or toluene, which also effect curing. The material may be pretreated with an acidic material such as sulphur dioxide which is stated to act as a catalyst and substantially reduce the curing time. Suitable derivatives of phthalaldehydic acid referred to are the 5-chloro and the 5- tertiary butyl compounds. Excess of the treating compounds are removed after curing by leaching. The Specification gives figures showing reduced shrinkage on drying of treated as compared with untreated wood.
