Title: Handling apparatus for gas-cooled nuclear reactor installation
IPC: G21C19/18
Filed: 1963-10-15
Abstract: A gas-cooled reactor enclosed in shielding 12 has a space 10 above the core receiving the fuelling apparatus A, the space being separated from the core by a shield wall 14 having openings 16, closable by plugs, for gaining access to the fuel element channels, the fuelling apparatus being connected to drive means situated outside the shielding 12 by drive cables extending through an aperture in the shielding. The fuelling apparatus A comprises a beam B supported for rotation about its central vertical axis by an annular bearing 18 fixed beneath the roof of the shielding 12. A tube 20 fixed to the centre of the beam extends through the shielding roof and serves for the passage of the drive cables. A carriage C having wheels 36 movable along rails 30 on the beam B supports a fuel element grab D and a lifting device E for fuel element transport containers 92. The beam B and a pressurized chamber 48 are rotated synchronously by motors 28 driving four shafts 26, pinions 24, 241 on the shafts meshing, respectively, with toothed concentric annuli 22, 221, annulus 22 being fixed to the beam and annulus 221 being fixed to the chamber. The pressurized chamber 48 is on the exterior of the shielding 12 and contains the various winches comprising the drive means for the drive cables for the motions of the parts C, D & E, these cables passing over pulleys situated at the upper and lower ends of the tube 20. The cable system is described in detail with reference to Fig. 2 (not shown). In operation, the grab D is brought over the desired opening 16 by movement of the beam B and carriage C, the plugs from that opening being first removed and then the fuel elements handled. The containers 92 are used for receiving spent fuel elements from the grab D or for introducing new elements through a passage in the shielding 12, these containers normally occupying storage stations situated around the periphery of the wall 14 and having claws 88, 90 engageable by claws 84, 86 on the lifting device E. In a modified arrangement, Fig. 5, the beam B has three trackways 30, 106, 108, the upper trackway 30 supporting the carriage C and grab D, the middle trackway 106 supporting a carriage F and the lower trackway 108 supporting a fuel element container G which may be moved from a storage station 112 on to the trackway 108 by claws 114 carried by the carriage F co-operating with members 116 on the container. To facilitate controlling the apparatus a replica of it to the same or a smaller scale may be arranged outside the shielding and controlled by cables operating synchronously with the cables of the apparatus. Specification 953,298 is referred to.

Abstract: A device for cleaning a diamond impregnated lap comprises a casing 11, a shaft 16 rotatably mounted and free to move axially in the casing, a wheel 25 fixed to an end of the shaft which projects from the casing, the face of the wheel being at right angles to the axis of the shaft and having grooves 27 to contain lapping paste, a handle 23 for rotating the shaft and a spring 22 urging the shaft in the direction to project the wheel from the casing. The wheel 25 is of synthetic resin and has a central cavity 28 to receive dirt removed from the lap. A base-plate 13 attached to the bottom of the casing 11 by screws has a spigot 14 received in a recess in the casing when the plate 13 is in the full-line position shown. For cleaning a lap rotating about a horizontal axis the casing is placed on a magnetic support plate with the end face of the wheel 25 close to the lap periphery. The handle 23 is pulled compressing the spring 22 and the casing pressed towards the lap the handle 23 is then rotated, the spring 22 exerting feeding pressures towards the lap. After removal of the device a spring 21 recentres the shaft 16. For cleaning the lap of a machine as described in Specification 1,010,409 the base-plate 13 is reversed and the spigot 14 which now projects is secured in a hole in the tilt bracket, a turret carrying tabs to be lapped having been removed from the tilt bracket.

Title: Slide-fastener assembly and method of making same
IPC: H02K1/32
Filed: 1967-03-03
Abstract: A sliding clasp fastener comprises two stringer tapes 1 each having a longitudinal row of perforations through which pass teeth 4, formed with enlarged interlocking heads 3, constituted by successive turns of a respective interlocking element 5 made from a filament of plastics material, each stringer tape having been made from a material possessing the ability to shrink in the transverse direction and having been shrunk behind the enlarged heads 3 of the teeth of the interlocking element to restrain the interlocking element from movement in one transverse direction with respect to its tape, the material between the perforations providing support for the teeth, there being means 13 e.g. or 'core to prevent relative movement in the opposite transverse direction between the element and the tape, whereby the element is held to the tape without the use of sewing threads. The shrinkage can be in the transverse direction only or in both the transverse and longitudinal directions and if the tapes are made of cotton it is carried out by a chemical treatment or by a hot wet treatmint if the tapes are made of synthetic threads they are shrunk by heating. When the teeth of the elements have been passed through the perforations for each tape a marginal portion is bent back so that it lies on the element overlying the main portion of the tape when the threads of the tapes are of synthetic materials the marginal portions can be heat treated so that they, are made springy so that they tend to remain in place on the teeth. The weft threads can be provided with enlargements at each end where they define the perforations to prevent the warp threads moving.

Title: Brake cable operating means
IPC: B60T11/08
Filed: 1968-09-25
Abstract: The invention relates to a foot-operated mechanism employing an overcenter toggle to actuate a brake cable. As described, a pedal 12 pivotally mounted at 10 drives a copivotal elliptical gear 14 meshing with a second elliptical gear 16, pivoted at 18 and provided on either face with a plate 20 connected to a cable operating yoke 26. To produce a quick take up of slack in the brake cable, the elliptical gears 14, 16 provide initially a low mechanical advantage which increases as the pedal is depressed and the toggle pivot 24 moves overcenter of the gear pivot 18 to lock in the "brake-on" position. The brake is released by a second pedal 50, pivoted at 18 and provided with a projection 50a which contacts the toggle pivot 24 to move it overcenter.

Title: Butterfly valve seat
IPC: F16K1/228
Filed: 1969-05-27
Abstract: A butterfly valve has a closure disc 13 formed as a segment of a conical surface which, in the closed position co-operates with a flexible seat formed from, e.g. a fluorine-containing polymer, having a portion 15 which is deflected by fluid-pressure to form a seal, and is arranged so that it deflects more when the pressure acts from the top in Fig. 3, than when the pressure acts in the opposite direction, so that the seat can seal on to the disc whatever side the pressure acts up to a maximum limiting design pressure of the valve. In Fig. 3 the difference in deflection is achieved by placing pivot points 30b and 31 at different radial distances from the centre of the disc but it can also be obtained by forming the seat with a graduated stiffness from one surface to the other. The valve has a motorized operator 11a.
