Title: Nuclear fusion reactor
Inventor: NIBLETT GEORGE BRYAN FRANCIS
IPC: H05H1/04
Filed: 1958-06-19
Abstract: 861,185. Pulse-generating circuits. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 16, 1959 [June 19, 1958], Nos. 19736/58. Class 40 (6). [Also in Group XL (a)] A circuit for generating a pulse with a fast rise time for operating a thermonuclear reactor comprises a condenser which discharges through a spark gap to the load, the spark gap being triggered by the discharge of a further condenser. In Fig. 2 condenser 15 is charged from D.C. source 13 until spark gap 19 breaks down thus causing the condenser 15 to discharge through cable 22 and break down spark gap 26 which allows condenser 34, previously charged from source 30, to discharge through cable 5 to the load (not shown). A condenser 41, precharged by source 30, and the associated plate of spark gap 26 prolong the discharge. In Fig. 2 a second identical circuit is shown, and in practice about a hundred identical circuits would be used. Specification 826,071 is referred to.

Title: Method of separating fatty alcohols
Inventor: RUSSELL HAROLD
IPC: C07C33/025
Filed: 1963-05-21
Abstract: Saturated and unsaturated fatty alcohols are separated from a mixture of such alcohols by dissolving the mixture in a normally liquid organic solvent, reducing the pressure of the atmosphere adjacent to the solution under essentially adiabatic conditions to cause evaporation of a substantial quantity of the solvent, so causing a rapid chilling of the solution so that the normally solid saturated fatty alcohols form interlocked agglomerations of crystals and the unsaturated alcohols remain in solution, filtering off the saturated alcohols and subsequently removing the solvent from the remaining solution of unsaturated alcohols.  The process is particularly applicable to those alcohols having at least 6 carbon atoms in the molecule, e.g. the alcohols obtained by the saponification of whale oil and those obtained by the reduction of fatty acids and their derivatives such as commercial oleic acid, tallow fatty acids and soyabean fatty acids.  Suitable solvents are, for example, methyl alcohol, ethyl alcohol, isopropyl alcohol, acetone and methyl ethyl ketone.  The solvents are preferably used in anhydrous form.
