Title: Improvements in or relating to arrangements for winding wire at high speed
IPC: B65H54/82
Filed: 1960-06-10
Abstract: 877,319. Winding and reeling wire. GODDERIDGE, J. June 10, 1960, No. 20509/60. Class 83 (4). Apparatus for winding wire into circular turns at high speed comprises a rotatably mounted capstan, a rotating head for winding several turns of the wire around said capstan, and a pressure device for pressing said turns in a downward direction, the pressure device comprising rotatably mounted pressure members located around said capstan just above the upper turn of wire, and means for cyclically displacing said pressure members downwardly parallel to the axis of the capstan by a distance equal to the diameter of the wire, each pressure member being returned to the upper position and occupying said position at the moment when the wire is applied to the capstan facing it. Wire 6 led down a hollow shaft 2, rotated by a pulley 3, to pass over guide pulleys 4 and 5 is laid by the latter, which is carried by an arm 21 on the shaft 2, around a capstan 7 rotated at a speed different from that of the arm 21 through gearing 9 and a shaft 8 carried by the shaft 2. The turns are held on the capstan 7 by flat springs, Fig. 1 (not shown), or by plates 15 urged by springs 16. An inclined ring 12 is rocked around the capstan 7 without rotation relative thereto by an inclined triangular plate 19 with a roller 18 at each corner which supports the ring. The plate 19 is rotated by the arm 21. The ring 12 is guided by a cup point 17 and has an inner spherical peripheral surface engaging a spherical surface on the capstan 7. The arrangement is such that the highest part 13 of the ring is always at the point where the wire is fed on to the capstan and the wire turns are pushed down a distance equal to the diameter of the wire as the ring rocks around the capstan. In modification, Fig. 6, the ring 12<SP>1</SP> is divided into six segments 25 urged inwardly on to the capstan 7<SP>1</SP> by springs 26 and is inclined by rollers 18<SP>1</SP>. In another modification, Fig. 9, the ring 12 has a castellated edge 35 interfitting with a castellated upper part of the capstan 7. Instead of the castellated ring individual elements 36, Fig. 10, of the same shape as the castellations may be used, being vertically slid relative to the capstan 7 by an adjustable roller 37. The elements 36 may be replaced by flexible lever members 40, Fig. 11.

Title: Canning for a nuclear fuel element
Inventor: BOUDOURESQUE BERNARD
IPC: G21C3/20
Filed: 1965-05-04
Abstract: 1,087,497. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 14, 1965 [May 26, 1964], No. 20520/65. Heading G6C. A fuel element can made of Mg-Zr alloy having a Zr content less than 1% by weight is provided on its inner surface with an antidiffusion layer of MgO and/or MgCOa and free C for preventing the diffusion of Pu through the can. Where the irradiation exceeds a threshold of some 1000 MWd/t, Mg-Zr alloy cans have reduced strength, in particular owing to the diffusion of the Pu formed when the fuel element is irradiated. This Pu diffusion also causes a disturbing contamination of the reactor fuel channels. The anti-diffusion layer of this invention is formed by heating the can in CO 2  gas at a pressure of from 1 to 60 kg./cm.<SP>2</SP> and at a temperature between ambient temperature and 550‹ C., for a period of from 10 to several hundred hours and long enough for the MgO and/or MgCO 3  to form but without effecting the structural and dimensional stability of the Mg-Zr alloy. Simultaneously there is a slight deposition of carbon. The working conditions determine whether the layer includes MgO, MgCO 3 , or both. The thickness of the layer is preferably between 0.1 and 25 microns.

Title: Process for the separation by extractive distillation of cyclopentane from neohexane
IPC: C07C7/08
Filed: 1956-07-12
Abstract: Cyclopentane is separated from hydrocarbon mixtures which also contain neohexane by submitting the mixture to extractive distillation using, as extractant, a lower monoalkyl ether of ethylene glycol or an aqueous solution thereof; a solution of cyclopentane in the extractant is withdrawn from the base of the distillation column.  In an example, a technical isohexane fraction obtained by fractional distillation of Venezuelan crude oil was distilled, and an azeotrope of cyclopentane and neohexane was collected.  This azeotrope was fed as a vapour to the middle of a distillation column; and the monomethyl ether of ethylene glycol was introduced at a higher level in the column.  The ratio by weight between the quantity of ether and the quantity of cyclohexane/neohexane mixture was 10 : 1.  The overhead vapours comprised about 70 per cent neohexane and about 30 per cent cyclopentane by volume.  A solution of cyclopentane in the ether was drawn off as bottom product which, on simple distillation, yielded cyclopentane having a purity of more than 99 per cent.
