Title: Spacer for fuel assemblies
IPC: G21C3/334
Filed: 1965-06-02
Abstract: 1,100,706. Fuel elements. ALLM€NNA SVENSKA ELEKTRISKA A.B. 2 June, 1965 [3 June, 1964; 31 Dec., 1964], No. 23465/65. Heading G6C. A fuel assembly for a nuclear reactor comprises a plurality of parallel fuel rods spaced apart by means comprising a rigid spacer body formed of tubular elements surrounding the fuel rods and spacer springs fastened to the tubular elements and arranged to bear against the fuel rods. The tubular elements which may be either circular or rectangular in cross-section are arranged in parallel rows and soldered or welded to each other and to an outer frame. In one embodiment (Figs. 3 and 4, not shown), four spacer springs are mounted on the outside of each tubular element with bent portions of the springs extending through apertures in the tubular element to support the fuel rod within. The bent portions have a mushroom-like shape making them resilient in both the axial and radial directions. In an alternative embodiment (Fig. 8, not shown), the tubular elements are formed by two groups of parallel intermediate walls intersecting at right angles, each tubular element so formed surrounding two fuel rods. Wave-shaped spring strips are fastened to both sides of the intermediate walls of one group and to the inner walls of the outer frame, and bear against each fuel rod at four points. Preferably the intermediate walls of the other group are lower than those of the first group so that they do not reach up to the spring strips. When inserting or removing the fuel rods, the spring strips are engaged between the fuel rods by pinching devices so that the fuel rods can be freely displaced in their axial direction. In order to fix the spacer body in the axial direction in relation to the fuel rods, some of these are divided and the parts joined together on each side of ring-shaped fixing discs arranged in the spacer body. In a further embodiment (Fig. 10, not shown), spacer springs with free-bearing tongues which bear against the fuel rods are fastened to both sides of each of the intermediate walls and to the inner walls of the outer frame. The middle portions of the springs are fastened to the walls and the freebearing tongues extend in opposite directions from these portions.

[Class 81 (ii).] In a stunning and casting pen of the type comprising a receptacle for the animal closed at one end and having closure means such as a hinged bar or doors at the other, the receptacle having circular end rails resting on supporting rollers, the receptacle is held in a vertical position by a detent engaging behind a projection on one of the rails whereby, when the detent is held out of the path of the projection, the pen turns under the action of the weight of the animal until stopped in a position such that the animal falls out, or in an intermediate position. A receptacle A, closed at one end and having a hinged bar at the other, is of V-shaped crosssection and is mounted by means of cross members C<1> and brackets D in two metal hoops B<1> running on rollers f<1>. The receptacle is located to one side of the centre so that there is a tendency to tip. Tipping is prevented by a stop g on the rail B<1> encountering a detent H which is moved by a lever h into or out of its path. A spring plunger acts as a buffer. After slaughtering the animal, the detent H is moved out and the pen turns until stopped by the top frame member E engaging a stop M. The carcass slides out down a slope K. A second stop g<1> is provided so that the pen can be stopped in an intermediate position, when the animal lies horizontally and can be slaughtered by the Moslem or Jewish method. After ejecting the carcass, the pen is swung back and is stopped in a vertical position by a stop g<2> encountering one of the pulleys f<1>. Specification 361,180 is referred to. According to the Provisional Specification, a stop on the end rail acts in place of the member E to stop the pen in the ejection position. The stops may be provided on one or both end rails.

Title: Improvements in or relating to electromagnetic relays or shutter indicators
IPC: G08B5/28
Filed: 1929-07-31
Abstract: 316,880. Telefonaktiebolaget L. M. Ericsson. Aug. 4, 1928, [Convention date ]. Single indication or two-position indicators.- Relates to electromagnetic relays wherein an electromagnet has a U-shaped core, the poles of which co-operate with an armature which forms an indicator, operates contacts or fulfils both functions. Fig. 1 shows a number of indicators associated with the jacks of a telephone switchboard. Each indicator comprises an electromagnet 2, Figs. 1 and 3, having a U- shaped core 3 the polar extensions 9, 10 of which co-operate with a plate armature 4. The armature is pivotally mounted at its inner side which comprises a sharp edge engaging grooves in wings 19 formed on a member 18 bridging the poles and held in position by a pin 21. The armature 4 has an arcuate extension 5 which forms the indicator shutter and also co-operates with the ends of the poles. The armature is held normally in the position shown against abutments on the member 18 by a spring 22 which is secured between the shutter and the fan 21. When the electromagnet is energized, the armature 4 is attracted against the upper sides of the pole pieces and the shutter is displayed through an aperture 6. The extension 5 also operates contacts 26, 27 when the armature is attracted and the armature is maintained in the attracted position by the spring 22 which during operation reverses its effect upon the armature. The armature is restored to normal position by a spring- controlled cam 31 which is pivoted on one pole piece and is operated when the associated plug 28 is inserted in the jack. When the plug is removed the cam is restored to its inoperative position but the armature remains in its normal position under the action of spring 22. The cores of the electromagnet 2 are fitted into an insulating plate 14 which also carries the contact springs of the jacks. In a modification the armatures are restored to normal position by the springs 22 upon de-energization of the magnets 2, the jacks and associated plugs being omitted. Specification 316,875 is referred to.

Title: Improvements in method and apparatus for moulding rubber endless belts and the like
IPC: B29D29/00
Filed: 1947-08-28
Abstract: 636,142. Moulding and vulcanizing rubber belts, gaskets, quoits &c. UNITED STATES RUBBER CO. Aug. 28, 1947, No. 23812. Convention date, Nov. 14, 1946. [Class 87 (ii)] Apparatus for curing rubber endless belts, gaskets, quoits, or the like, comprises a hollow mould member provided with a series of moulding grooves for receiving the uncured belts &c., a metal pressure band wrapped round the mould member and contacting the exposed surfaces of the belts, and means for building up a differential pressure between the external surface of the pressure band and the belt contact face therof to force the uncured belts into intimate contact with the moulding grooves. A wheeled carriage 2, Fig. 1, on rails 5 has a rubber or fabric cover 21, and a number of openings 20 each connected to a manifold 22 which in turn connects to a pipe system 23 exhausting to the atmosphere. The mould member may consist of either a single hollow cylinder suitably grooved, or an assembly of mould rings 7 stacked to form a series of moulding grooves 8, a mould 13 having a pressure area 14 being placed at the top. The mould rings and belts are assembled as shown in the right hand part of Fig. 1, the exhaust 20 opening into the interior of the chamber formed by the nest of mould rings and the pressure surface. The pressure band 16 of flexible sheet steel &c. having overlapping tapered ends 18 is placed around the nest of rings so as to contact the slightly oversize belt carcasses 9, and a shim 19, Fig. 3 (not shown), is placed between the edges 18 and the belts. Spiral springs 17 are then snapped over the band to hold it in place. The carriage, with the assembled rings, is then pushed into the vulcanizer 3, and cured by steam under pressure. The steam passes down a passage way 25 between the band 16 and the mould rings and belt carcasses, through the bleed holes 15 to the exhaust opening 20, heating and softening the belts and at the same time building up a differential pressure, since the interior of the chamber of the mould rings is maintained at substantially atmospheric pressure. As the differential pressure increases the overlapping ends 18 of the band slip over one another to force the belts into the mould grooves 8. The pressure also acts on the surface 14 of the mould 13, forcing the rings and band on to the sealing surface 21 so that there is no appreciable leakage of steam past the mould ring into the chamber. The differential pressure may be controlled by varying the steam pressure. The exhaust outlet 20 may be closed midway of the curing time, allowing the pressure to build up in the chamber and speed up the process. After vulcanization is complete the carriage 2 may be removed and the assemblies dismounted and re-stacked for a further operation. The differential pressure may be increased by creating a vacuum in the chamber.
