A diagrid 10 for supporting all the fuel assemblies of a reactor core is formed by a pair of upper plates 8a, 8b and a lower plate 8c, between which plates the support tubes 9 extend. The end-fitting 1 is provided at its lower end 14 with a guiding device comprising a spherical bearing 15 which is applied in leak-tight manner against an annular shoulder 16 formed on the internal wall of the support tube 9. Below the shoulder 16 a nut 17 having a cylindrical head 18 is fixed in the support tube 9, the head 18 engaging in a recess in the lower end 14 of the end-fitting 1 to provide a restraining latch, the purpose of which is to permit the positioning of the fuel assembly only in the location for which it is specifically intended. The coolant which is at low pressure is admitted through apertures 11 in the support tube 9 located between the upper plates 8a, 8b of the diagrid 10 as indicated by the arrows F.

Title: Process for the preparation of a salt of optically active lysine
IPC: C07C59/68
Filed: 1968-12-14
Abstract: The invention comprises the mono salt of lysine and phenoxyacetic acid, preferably the optically active salt. The salt is prepared by conventional salt-forming methods, e.g. by reacting racemic lysine with phenoxyacetic acid in aqueous solution, followed, if desired, by resolution into the D-and L-antipodes by seeding a supersaturated solution with the desired optical antipode, the remaining antipode may then be racemized by heating in aqueous solution and the resolution repeated. Alternatively, the solution containing the remaining antipode may be saturated with the racemic salt of lysine and phenoxy-acetic acid, whereupon the remaining antipode separates out, since the D- and L-forms are insoluble in a saturated solution of the racemic salt.

Title: Cationic polyurethanes
IPC: C08G18/32
Filed: 1974-12-16
Abstract: Cationic polyurethanes are prepared by reacting a monomeric, aliphatic dihydroxyl compound containing a maximum of 7 atoms between the two hydroxyl groups and containing an aliphatic radical having at least 10 carbon atoms on one of said atoms with a polyisocyanate to give a preadduct containing NCO end groups, chain-extending the resultant preadduct by means of an aliphatic monomeric diol containing tertiary nitrogen, and converting the chain-extended product into an ammonium compound. These polyurethanes are particularly suitable as the active component in paper sizes. The sizes can be employed both in bulk sizing and in the surface sizing of paper and give sized papers having a high degree of sizing and a low Cobb value. Sizing in a relatively broad pH range is possible, and the polyurethanes can be processed very well together with products usually used for sizing.
