Abstract: 1228781 Stud and socket fastenings AVDEL Ltd 1 Aug 1968 [9 Aug 1967] 36589/67 Headings F2H and H11B A blind rivet of resilient material comprises a plug 12 and a shell 15 the shell having a radially enlarged head 14 at one end of the shank and the plug 12 at the other end of the shank, the rivet having a central longitudinal bore which extends completely through it, the arrangement being such that on drawing the plug into the shell by means of a suitable mandrel 31 with a radially enlarged head 36, which passes through the bore in the stud so that the plug expands at least the tail end part of the shell and is retained in the shell. In the construction shown the plug is connected to the shell by means of a thin annular web portion 18 which breaks when the mandrel starts to draw the plug into the shell. Adjacent the web 18 the plug has a flange 28 which extends into the bore and the head of the mandrel bears against this flange to draw the plug into the shell. The opposite end portion of the plug also has a flange 27 which extends outwardly and which limits the movement of the plug into the shell. The exterior surface of the plug is formed with a number of circumferential corrugations 21 which start at the shell end of the plug and after the corrugations, the plug is formed with four longitudinally extending ribs 23 which have sinuous crests, the ribs being formed by providing grooves which extend into initially circumferential corrugations. The ribs are thin and fairly easily deformed and the bottom of each groove between the ribs is a thin web 24. When the mandrel has pulled the plug into the shell so that the end of the shell engages the flange 27 of the plug a further pull on the mandrel pulls it out of the rivet'through the restriction in the bore caused by the flange 28 and this distorts the plug and causes a permanent set which is allowed for by an enlargement of the bore in the head of the rivet. The corrugations of the rivet distort the wall of the shell when the plug is drawn into the shell and cause the wall to expand to completely fill holes 45 through two workpieces joined together by the rivet. The part of the shell beyond the workpieces is expanded radially but the tailmost part curls radially inwards beyond the ribs 23 to engage the flange 27.

A composite polyurethane foam is prepared by introducing into an open-pored polyurethane foam a liquid composition comprising one part of a polyurethane foam-forming mixture and subsequently a vapour comprising the complementary part of the polyurethane foam-forming mixture, the vapour comprising at least one ingredient necessary for the polyurethane foam reaction, and the liquid composition and the vapour being allowed to react or the vapour being allowed to function as a catalyst, to form a polyurethane foam within the open pored foam. The open pored foam may be a flexible foam which may be reticulated before or after the composite foam has been produced. The preferred vapour is steam but it may be an amine catalyst such as triethylamine or N-methyl morpholine. It is preferred to use the liquid composition comprising one part of the polyurethane foam forming mixture in the form of a polyurethane prepolymer. This prepolymer is usually spread on the surface of the open pored foam which is passed through rolls to secure uniform distribution'and then supported or suspended in a vessel in which the vapour is present. The foam may be compressed during the introduction of the vapour. Both the foams can be either a polyester or polyether based foam.

Fig. 1 shows a 2-pole concentric winding having two parallel paths designated 10, 11 and 12, 13 respectively. Under steady state conditions corresponding points, such as 32, 33 on the end portions of the winding are at the same potential and these points are linked by connection 31. Other connections are shown at 34 ... 36 and 44 ... 47 and all are cylindrically arranged on the end faces of the rotor. Such connections, together with the portions of the winding in the slots form concentric turns on the quadrature axis of the rotor through which current circulates under fault conditions. Fig. 2 shows a two-layer, two-pole lap winding having two parallel paths again designated 10, 11 and 12, 13. Equipotential connections are made at the points 60, 64 ... 70 and 71 ... 78 between the two tiers of end connections resulting in the production of sets of short turns and long turns, the latter linking the quadrature axis. In another embodiment, Fig. 3 (not shown), a two layer lap winding with four paths is employed. The paths are connected either in parallel or pairs of parallel paths are connected in series and the paths are wound such that each of the two paths of a pair linked to the direct axis is also linked with the quadrature axis.

Abstract: 1296554 Fuel elements NUCLEAR POWER GROUP Ltd 12 June 1970 [19 June 1969] 31126/69 Heading G6C A fuel element stringer includes a spring, the force of which prevents separation of the fuel elements which might otherwise occur during on-power loading of the stringer due to coolant gas forces being sufficient to separate adjacent fuel elements, thus allowing coolant gas to bypass some of the elements with resultant overheating. As shown, a graphite sleeve 3 is located beneath the lowermost element 2 of a plurality of fuel elements assembled end-to-end on a tie-bar 1, and a steel sleeve 4 supported by the tie-bar 1 is located within the graphite sleeve 3. In an annular space 5 between the two sleeves is located a spring 6. When the stringer is being lowered into the reactor core, the spring force prevents separation of the fuel elements by tending to push the fuel elements upwards and the tie-bar downwards. Expansion of the spring 6 is limited by pins 7 which come up against a lip 4b on the sleeve 4 at the limit of spring movement. When the stringer is in position in a bore in the reactor core the weight of the fuel elements is sufficient to fully compress the spring 6 so that a lip 3b on the sleeve 3 abuts the upper surface of the lip 4b.
