Title: Preparation of organic silicon derivatives
IPC: C07F7/18
Filed: 1962-05-25
Abstract: Compounds of the general formula RnSi(OR1)4-n, wherein R is a hydrocarbon radical, R1 is a phenyl radical optionally substituted by one or more alkyl groups, and n is 0, 1, 2 or 3, are prepared by reacting a chlorosilane of formula RnSiCl4-n with phenol or an alkyl subsiituted phenol in presence of from 0.05 to 1.0% by weight of dimethylformamide based on the total reaction mixture. R may be methyl, ethyl, isopropyl, vinyl, allyl, cyclopentyl, cyclohexyl, cyclopentenyl, cyclohexenyl, phenyl, benzyl or tolyl.  Substituted phenols used include cresols, xylenols, butylphenols and octylphenols.

IPC: H01F36/00
Filed: 1961-06-06
Abstract: 982,686. Transformers. INTERNATIONAL RESEARCH & DEVELOPMENT CORPORATION. June 6, 1961, No. 20357/61. Heading H1T. In a superconductive transformer the primary and secondary windings comprise a plurality of coil layers, the layers of one winding being interleaved with the layers of the other winding to mimimize the magnetic fields linking the coil conductors there being a critical value of flux beyond which the superconductive state is destroyed. The windings are of wire or foil and may be in concentric cylindrical helical coil layers as Fig. 3 or interleaved disc coils (Fig. 15, not shown). The primary and secondary conductors may be of the same gauge and have the same number of layers, the coils of one winding being connected in series parallel and of the other in series (Fig. 4, not shown). The coils may be wound on phenolic plastic former and the conductors may be insulated with " Teflon " (Registered Trade Mark) and may be of tin, niobium or lead. The windings are enclosed in a heat insulation jacket connected to a refrigeration system and the core is outside the jacket (Fig. 7, not shown). As shown sectionally in Fig. 10, the jacket is in the form of a toroidal shaped double Dewar vessel comprising an outer vessel having an outer glass wall 26 separated by a vacuum space 27 from an inner glass wall 28 and an inner vessel having inner and outer glass walls 29, 31 separated by a vacuum space 30. The middle volume between walls 28, 29 is filled with liquid nitrogen 32 and the volume between the wall 31 and the windings is filled with liquid helium 33, and the vacuum space walls may be silvered. A method of forming the Dewar vessels around the preformed coils is briefly described. The leads to the transformer winding, which may be of copper, nickel or aluminium, pass through a ducting into the Dewar vessel jacket and in order to reduce the power required for the refrigeration of the windings the leads may be subjected to several stages of refrigeration before entering the jacket (Fig. 13, not shown). The application to single and three phase transformers is suggested and some design details for a 10MVA transformer are given.

Patent GB-763932-A (GB)
Title: Manufacture of ethanolamines
Filed: 1951-08-31
Abstract: Di-ethanolamine admixed with tri-ethanolamine is prepared by continuously passing a substantially anhydrous mixture of monoethanolamine and ethylene oxide containing at least 2 mols. of the amine per mol. of ethylene oxide present and less than 1 per cent by weight of water under a pressure which maintains the mixture in the liquid state through a reaction zone initially heated to 50-110 DEG  C. and thereafter maintained at 50-150 DEG  C., the contact time within the reactor being such that substantially complete reaction of the ethylene oxide takes place.  Preferably 5-7 mols. of monoethanolamine are used per mol. of ethylene oxide with pressures of above 20 atmospheres, temperatures of 80-120 DEG  C., and contact times of 30-300 seconds.  The ethanolamine may contain up to 10 per cent by weight of di- and tri-ethanolamines. In examples, monoethanolamine and ethylene oxide, respectively, containing 0.2 and 0.03 per cent of water, are separately and continuously fed by proportionating pumps to a mixer from which the mixture passes through a 75 foot stainless steel tube of bore 0.154 inches immersed in a bath of refluxing liquid, e.g. water or methanol to control the temperature at desired level, a needle let-down valve on the tube outlet being adjusted to establish the required reactor pressure. The product passing the valve flows to a continuous still operated under reduced pressure to remove unreacted monoethanolamine for re-use and the residual mixture of di- and tri-ethanolamines is withdrawn for fractional separation. The mono-ethanolamine starting material may be prepared as described in Specification 760,215. U.S.A. Specification 2,373,199 is referred to.  According to the Provisional Specification, ethanolamines are prepared by continuously passing a substantially anhydrous mixture of an ethanolamine having at least one hydrogen atom directly attached to the nitrogen atom and ethylene oxide, containing not more than 50 per cent, preferably not more than 35 per cent, by weight of the oxide, under a pressure which maintains the mixture in the liquid state through a reaction zone heated to from 50 DEG  to 120 DEG  C. and maintained within the range of 50 DEG  and 300 DEG  C., the contact time within the reaction zone being such that substantially complete reaction of the ethylene oxide takes place.  A further example is given.

Title: Removal of certain fission product metals from liquid bismuth compositions
IPC: G21C19/50
Filed: 1959-06-18
Abstract: Metallic fission products which form chlorides less stable than UCl3, particularly Pd, Ru, Rh, Se, Te, Nb and Zr, are removed from liquid Bi or solutions of U in liquid Bi by agitation with small amounts of zinc in an inert atmosphere preferably in the range 400-500 DEG  C. and removal of the solid phase containing zinc and fission products which forms.  To separate Zr, it is necessary to cool to 270-300 DEG C., but the other metals are almost completely removed at 350 DEG  C. The solid phase may be removed by skimming or by filtration through a porous inert material such as graphite.  Residual Zn may be removed by vacuum distillation. Loss of U by oxidation may be minimized by the addition of small amounts of metals, e.g. 100-300 parts per million of Mg, which form oxides more stable than uranium oxides. Fission products forming chlorides more stable than UCl3 may be removed from the solution by extraction with a fused chloride salt mixture which may contain an oxidizing agent.  Exemplified is the ternary eutectic NaCl-MgCl2-KCl containing BiCl3 as oxidizing agent.
