Abstract: A system for navigating among resources includes a target detection module detecting whether a first resource has been branched from to two other different resources and a backward navigation module operable to detect selection of a backward navigation button and cause navigation to the first resource. A method includes designating a target resource accessible via a backward navigation button in a first browser session, detecting selection of the backward navigation button in a second browser session, and navigating to the target resource in the second browser session. The method can involve detecting hovering of a pointer icon over the backward navigation button and responsively presenting a thumbnail of a resource associated with the backward navigation button.

Abstract: A method includes storing one or more resource identifiers identifying one or more associated resources visited using a browser application, and presenting the resource identifiers in an order designated by one of a plurality of history presentation settings and resource navigation context specifications. The history presentation setting and navigation context can be selected by a user. Exemplary history presentation settings include chronological and domain-name grouped. Exemplary navigation context includes resource identifier, such as name, URI, or domain of the currently viewed resource. The method may further include presenting a thumbnail when a pointer icon is positioned over one of the resource identifiers.

Abstract: Apparatus for rectifying the tendency of a fuel assembly (1) to incline from the perpendicular has a top nozzle support (19) and a base assembly (18) for supporting, respectively, a top nozzle (7) and a bottom nozzle (2) of the fuel assembly. Incorporated in the base assembly is an elevating device (78, 79) which is operable to raise the fuel assembly. When raised, a grinding assembly (62) in the base assembly is able to remove material from the lower surfaces of the bottom nozzle so that they lie in a horizontal plane. The elevating device comprises a gimbal mounting arrangement which includes a gimbal (94) movably supported on a gimbal mount (88) by means of cooperating male and female spherically-shaped bearing surfaces. The grinding assembly includes a grinding wheel (66) which is mounted on a rotor (43) arranged for rotation about an axis along which the elevating device raises the fuel assembly so that material can be removed from each of the lower surfaces during one revolution of the rotor.

Abstract: An apparatus for handling nuclear fuel rods, which include a mixed oxide fuel material, and for constructing fuel assemblies from the fuel rods, includes a store (9) constructed from radiation shielding material. The store includes a number of channels (10), each of which is adapted to receive a magazine (2) containing fuel rods. Removal and insertion of magazines from and into the channels is effected by a handling machine (29) which is remotely and automatically operated. Each of the channels is closed by a plug (11) which can be removed and inserted by the handling machine. The handling machine is able to remove a magazine from a selected channel and to deliver the magazine to either of two fuel assembly lines (16, 21). Each assembly line constructs a different type of fuel assembly from that of the other assembly line, and each assembly line is arranged in a separate shielded enclosure (15, 24).
