Patent GB-506855-A (GB)
Abstract: 506,855. Hydrocarbon polymer compositions. KABELWERK VACHA AKT.- GES. Feb. 14, 1938, Nos. 4597, 4598, and 4599. Convention dates, Feb. 13, 1937, May 31, 1937, and July 6, 1937. [Class 2 (iii)] An electrical insulating-material consists of a mixture of polystyrol and polyisobutylene, the polyisobutylene being in the proportion of 10 per cent to 95 per cent of the mixture, with or without an addition of bitumen. The ingredients are mixed in a kneader at an elevated temperature, e.g. 100-200‹ C. and are worked up by extruding or calendering while hot. The shaping operation may be effected under pressure either in air or water vapour. When the mixture is to be extruded, a suitable solvent, e.g. carbon tetrachloride, or monomeric styrol may be added, the styrol being polymerized during the subsequent shaping. The feed of the plastic material to the extrusion mouthpiece is effected by means of a piston which exerts essentially a thrusting force without resulting in any relative displacement of the particles of the mass. The material may be worked up into flat pieces, or foils or into other shapes by profiled rolls, may be extruded on to a wire or conductor, or formed into insulating bodies for high frequency air-space conductors.

Title: Improved self locking threaded elements
IPC: B21K1/70
Filed: 1964-12-24
Abstract: 1,045,520. Making nuts. M. HATTAN, A. H. GOERING, and W. P. GREEN. Dec. 24, 1964, No. 52507/64. Heading B3A. [Also in Division F2] A filamentary element 12, e.g. of stainless steel, is coiled to the general form of a helix so that the inner surfaces 21, Fig. 5, form a female screw-thread, a portion 28 of the coil being deformed radially inwardly to lock on a bolt screwed into the coil and the remaining portion 27 of the coil having its turns secured together by brazing or an epoxy cement material 41 between the turns and/or (if the element is used with a surrounding housing 11) between the coil portion 27 and the inner surface 13 of the housing. The coiled element 12 may be used alone, as a nut, or secured in a housing 11 to form a composite nut which could be externally of polygonal section, Fig. 1 (not shown), or of circular section, Fig. 7 (not shown), but with a tubular extension 47 which can be peened outwardly to anchor the nut in a plate aperture 50. It can be used to provide a thread in a bore in a large body. The housing 11 is cut from tubular stock and reamed or honed to increase the internal diameter slightly. Tapering spaces 30 between the turns of the coil are present because the surfaces 25 of the element are caused to converge outwardly by the act of coiling. The portion 27 of the coil 12 when its turns are secured relatively to one another is of frusto-conical form, being almost entirely expanded on a frusto-conical male portion 34 (which may bear a taper thread) of a jig 31, Fig. 4, in which the coil is held for brazing or cementing. Alternatively, the conicity is achieved by making the internal surface 13 of the housing 11 conical. Most of the lowest turn 35 of the portion 27, extending out of the housing into a jig recess with a helical base 132, is ground or cut off, after securement of the coil 12 in the housing 11, to form a flat bearing face with the bottom 16 of the housing. In Fig. 7, the lowest turn is within the housing 11a and abuts a member 42 (with a helical surface 44 and a shoulder 42a) located between the coil 12a and extending member 47.

Title: Nuclear Reactor Fuel Elements.
Inventor: SAUNDERS ALAN CHARLES ANTHONY
IPC: G21C3/28
Filed: 1966-11-29
Abstract: 1,154,618. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 26 Oct., 1967 [29 Nov., 1966], No. 53465/66. Heading G6C A fuel element comprises a stack of ceramic pellets of fissionable material contained within a sheath having an end closure joined to an end face of the sheath by a butt weld, the ceramic pellet adjacent the butt weld having a lower fissionable isotope content per unit volume than the majority number of the remaining pellets. In the fuel element shown, a stack of UO 2  pellets 1, 1a is contained within a Zr alloy sheath 2 having end closures 3, 4 joined to its end faces by electrical resistance butt welds 5, 6. A compression spring 7 serves to consolidate the stack to prevent damage to the pellets during transportation of the fuel element. The lowest pellet 1a of the stack is of natural UO 2  whilst the remaining pellets 1 are enriched in the isotope U-235 to the value of 3À25 C 0 . The pellet 1a has a chamfer 8 at the end abutting the end closure 3 forming a peripheral recess encircled by the butt weld 5. The outside diameters of the pellets 1, 1a and the inside diameter of the sheath 2 are such that the pellets freely enter the sheath on assembly. During operation, the enriched pellets 1 expand to fit the sheath 2 closely, but because the lower pellets are subject to lower neutron flux, the end pellet 1a, being of lower fissile content, generates less heat than the enriched pellets 1 and remains freely fitting of the sheath. Axial force caused by extension of the stack can thereby be accommodated by ductile extension of that part of the sheath 2 which extends over the freely fitting end pellet 1a instead of concentrating tensile stress on the weld 5, and hoop stress on the weld is eliminated. The chamfer 8 provides a clearance between the pellet 1a and any welding flash thrown up on the inside of the sheath, thus avoiding the imposition of axial force on the flash with subsequent localised stressing of the weld. In an alternative construction in which the weld is disposed intermediate the ends of the end pellet, the clearance is provided by a circumferential groove instead of an end chamfer.
