Title: Process for obtaining chlorides of the cerium group free from thorium
IPC: C01F17/00
Filed: 1933-03-09
Abstract: Hydrated chlorides of the cerium group free from thorium are precipitated by passing hydrogen chloride into a solution of the rare earth metal chlorides containing also thorium chloride cooled to about 0 DEG  C. or below, say to - 5 DEG  C., or by the addition of chlorides such as of calcium or magnesium, with or without hydrogen chloride, the said chlorides being more soluble than cerium chloride and not precipitated by hydrogen chloride at room temperature.  In the latter method, it is unnecessary to cool the solution, a temperature of 20 DEG  C. being specified.  The precipitated chlorides are washed with cooled concentrated hydrochloric acid.  In an application of the process, a reaction melt obtained by decomposing monazite sand in any desired manner is dissolved in hydrochloric acid, the major part of the chlorides of the cerium group precipitated as above, and the filtrate treated to precipitate the metals of the yttrium group, the remainder of the cerium group and the thorium as oxalates, from which thorium is separated in known manner.

The collector of an electron beam tube, e.g. a klystron or a travelling-wave tube, which is fluid stage cooled-i.e. which has two or more coolant conduit systems, each cooling a different part of the length of the collector and each having its own coolant inlet-has its internal surface so shaped that the region between one stage of cooling and the next is subjected to a substantially reduced intensity of electron bombardment, whereby the formation of a hot-spot in this region is prevented. The collector shown has two stages of cooling provided by sets of coolant conduits 1 and 6, respectively, each provided with water inlets 2 at their lower ends and steam draw-off pipes 5 at their upper ends (shown only for conduits I). Electron impact on the region 11 between the two stages is reduced by making its surface tangential to the path of the electron beam, which diverges from the collector entrance 3 with a cone angle of α, the two cooled regions 9 and 10 being shaped, in accordance with a quoted formula, to ensure substantially uniform power input per unit area. Substantial departure of the surface 11 from the tangential condition is permissible.

Class 37 Tn a liquid level gauge using an immersion type measuring condenser 1, at least one reference condenser 2 is connected in series with the measuring condenser across an A.C. supply derived, e.g. from an oscillator 4 through a transformer 3, and the output voltage of the oscillator is so controlled, e.g. by a voltage regulator 5 that a constant voltage is maintained across the reference condenser 2 the junction of which with the measuring condenser is earthed. Under these conditions the potential across the measuring condenser is, assuming a constant value for the reference condenser, inversely proportional to its capacity, and after amplification at 6 is compared with the constant voltage output of regulator 5 to indicate the liquid level at 7. The reference condenser 2 is preferably wholly immersed in the liquid in which case changes in the liquid dielectric strength are substantially compensated. A second reference condenser having as dielectric the fluid above the liquid in question may be connected in parallel with the reference condenser 2 to give absolute independence of the dielectric constant of the liquid at one predetermined depth.
