Title: Nuclear fuel assembly
IPC: G21C3/324
Filed: 1969-01-16
Abstract: A fuel assembly adapted to be vertically positioned between adjacent fuel assemblies or other structural parts (such as moderator bricks) of identical shape to constitute a reactor core, and to be inserted/withdrawn by vertical displacement, has a central portion A of polygonal cross-section and two end portions B, C of relatively short length, the lower end portion B having a smaller cross-section than the central portion A and being provided with lugs 32 which each terminate in a bevelled tip and which lie on the lines of extension of the edges of the polygonal cross-section, and the upper end portion C being provided on each lateral face with a V-shaped ramp for abutment with the bevelled tips of adjacent fuel assemblies or other structural parts and guiding the lugs 32 of these fuel assemblies or other structural parts towards the edges of the polygonal cross-section. The central portion A comprises a casing 10 occupied by fuel pin bundles (not shown). The bottom portion B comprises an end connector 12 pierced by a central coolant duct and welded at 16 to the casing 10. A cylindrical extension 24 at the lower end of the connector 12 is intended to engage in a support grid (shown in chain-dotted lines in Fig. 1). Each lug 32 has a longitudinal ridge which forms an extension of the corresponding ridge of the casing 10. The lower end of each lug 32 has two bevelled facets, the ridge 36 between them being preferably rounded and inclined to the axis of the fuel assembly in a direction such that a thrust exerted on the ridge tends to centre the fuel assembly. The top portion C comprises an end connector 18 pierced by a central coolant duct 20 and welded at 22 to the casing 10. An annular groove 26 in the duct 20 is intended to accommodate the claws of a grappling device (shown in chain-dotted lines in Fig. 2). A ramp formed by two facets 38 and having the shape of an inverted V is provided at the extremity of each face of the end connector 18. In order to prevent two lugs 32 from coming into contact with two ramps at the same time and thus jamming the inserted fuel assembly, the ridges 36 of the lugs 32 are at different levels. When the fuel assembly is lowered into position, the ridge 36 of one of the lugs 32 comes into contact with a facet 38 on an adjacent fuel assembly or other structural part and as it slides over the facet 38, the inserted fuel assembly is caused to rotate. Each lug 32 is in turn brought into contact with a ramp and the rotation continued until the ridges 36 are in line with the edges of adjacent fuel assemblies or other structural parts.

Title: Process for relaxing internal tensions of textured synthetic yarns
IPC: D02G1/02
Filed: 1969-02-08
Abstract: A process for equalising the internal tensions in synthetic textile yarns which have been textured by temporary high-twisting and heat setting in the highly twisted state comprises subjecting the yarn to further temporary high twisting in the direction opposite to that in which it was previously high twisted but without a heat setting treatment in the high twisted state, the yarn being subjected to a heat treatment either before or after the said further temporary high twisting. In a preferred embodiment, a multifilament yarn 2 is fed from a bobbin 1 via feed rollers 3 and a heater 4 to a false twister 5. The heat set highly twisted yarn then passes through feed rollers 6 to a heating device 7, to equalise internal tensions in the yarn, and is taken off by feed rollers 8 rotating at a speed 10-15% slower than that of the feed rollers 6 to allow the yarn to contract. The rollers 8 feed the equalised yam to a second false twister 9, which rotates in the opposite direction to the false twister 5, and the yam is fed to a takeup package 11 by feed rollers 10. The yam is preferably slightly stretched during the second false twist treatment. The heaters 4 and 7 are preferably heated contact surfaces but may be hot air heaters. In an alternative embodiment, the yam after the first false twist and heat setting treatment is wound into a package which is steamed in an autoclave to equalise internal tensions in the yarn. The yam is then taken from the steamed package and passed through a false twister so that a twist is imparted in the opposite direction to the first applied twist, and the yarn is wound into a package. In a further embodiment, the heat treatment to equalise internal tensions may be combined with subsequent necessary yarn treatment processes. Yarns specified are multifilament polyamide or polyester yarns of 100-200 denier.

IPC: B60Q1/26
Filed: 1969-04-10
Abstract: In a signal light device for automobile vehicles comprising a lamp 1, 2 of a signal light adapted to be temporarily connected to an electrical source when a signal is to be emitted and a photo-sensitive element 8 controlling the intensity of the lamp 1, 2 as a function of the level of the ambient illumination, the lamp 1, 2 is connected in series with the emitter-collector circuit of a transistor 6 to the base of which the ', photo-sensitive element 8 is connected and an auxiliary lamp 9 having a resistance which varies in a non-linear manner as a function of its energizing voltage is connected between the emitter and collector of the transistor whereby a decrease in luminous intensity of the signal lamp 1, 2 takes place only below a predetermined ambient illumination. The signal lamps 1, 2 may be the vehicle stop lights or trafficator lights and the auxiliary lamp 9 may have a tungsten filament with a nitrogen, hydrogen or argon atmosphere. The photo-sensitive element 8 has a maximum resistance in darkness so that transistor 6 is biased OFF and the intensity of illumination of the signal lamps 1, 2 is controlled by the auxiliary lamp 9. As the ambient light increases to a point intermediate darkness and daylight the resistance of the photo-sensitive element 8 decreases and transistor 6 conducts to increase the intensity of signal lamps 1, 2. When maximum daylight occurs the photosensitive element 8 is at its minimum resistance and the transistor 6 is.fully conducting, making the voltage drop across the auxiliary lamp 9 zero to give maximum intensity to signal lamps 1, 2.
