Title: Improvements in and relating to apparatus for operating electric discharge tubes
IPC: H05B41/24
Filed: 1933-09-23
Abstract: 430,821. Supply systems for highfrequency vacuum &c. lamps. FODOR, J., Mount Park, Harrow-on-the-Hill, Middlesex, and NORTH, V. B., Boldshaves, Woodchurch, near Ashford, Kent. Sept. 23, 1933, No. 26315. [Class 38 (iv)] Apparatus for energizing a number of similar or different luminous electric discharge tubes with high-frequency current comprises a high frequency transformer the secondary side of which comprises several circuits, characterized by each of the secondary circuits feeding a different tube and comprising suitable inductance, capacity, or resistance, or combinations of these whereby the natural frequency of that circuit is adjusted to supply the tension, whether constant or varying, required by its corresponding tube. In one form the invention comprises a high frequency transformer 3, Fig. 1, with a number of separate secondary windings 4<a>-4<c> each feeding a separate discharge tube 5<a>-5<c> through circuits 6<a>-6<c>. The secondary sides are all tuned according to the tube requirements and, in order to correct asymmetric distribution of tension caused by the tube or the leads thereto, the secondary winding of the transformer may be earthed at its tension symmetry centre. Alternatively an adjustable condenser may be connected in the lead to each end of the tube. These devices may also be employed to impart a higher tension to one end of the tube than to the other and, by providing means to vary periodically the earthed point or the value of the capacities, the tension may be varied periodically. Condensers 7<a>-7<c> shunted across the leads to the tubes 5<a>-5<c> are of such capacity that they eliminate capacitive variations which may occur either in the leads or the tubes, and constitute a factor in the initial timing of the tube circuit. Alternatively capacitive variations may be neutralized by a small condenser in series with the secondary winding and tube. Fig. 12 shows one tube 5 of a series including a shunt capacity 7 together with ohmic resistances 15, 16 which are connected in the tube leads to produce an aperiodic circuit. In a modification the secondary side 4, Fig. 2, of a high frequency transformer 2 is constructed as a potential divider by tappings 4<a>-4<c> which permit of adjustment for the voltages required by the tubes 5<a>-5<c> and also the selection of the values of the self inductance influencing the natural frequency of the circuits 6<a>-6<c>. Separate pairs of tappings may be taken for each tube. Further modifications comprising ohmic and capacitive potential dividers are described.

Title: Preparation of uranium compounds
Inventor: BOURGEOIS MICHEL
IPC: C22B60/02
Filed: 1961-07-20
Abstract: Uranium compounds are prepared from an alloy containing uranium and molybdenum, e.g. an irradiated nuclear fuel, by p  treating said alloy with a gaseous mixture containing hydrogen halide and molecular oxygen, the alloy, at least initially, being at a temperature from 100 DEG C. to 300 DEG C. in order to initiate the desired reaction. The preferred hydrogen halides are HCl and HF, and the molecular ratio of these halides to the oxygen in the gaseous mixtures used is from 0,5 to 10.  The products are said to be oxides of uranium when the HCl-oxygen containing mixture is used, and uranium oxyfluoride and uranium fluoride when HF and oxygen are used.  The product obtained which is substantially free of molybdenum can be fluoridized by treatment with fluorine or a halogen fluoride and then distilled to obtain substantially pure UF6, or alternatively, the uranium can be extracted from the oxide product by any suitable method.  In addition to oxygen and hydrogen halide, the gas mixture may contain one or more gaseous diluents, e.g. up to 73% by vol. of nitrogen.
