摘要： A sports racket has a handle and a multi-frame. The multi-frame includes a primary frame defining a throat connected to the handle and a hoop-shaped head connected to the throat and encompassing an open region. The head has a plurality of stringing holes defined therethrough for attaching stringing to the head and across the open region. The multi-frame also includes supplementary frames and ribs. The supplementary frames are disposed in spaced relation and adjacent to opposite sides of the primary frame. The supplementary frames are coextensive with all or a portion of the primary frame head, plus all or a portion of the primary frame throat. The ribs are spaced from one another and extend between and rigidly interconnect the supplementary frames with coextensive portions of the primary frame. The ribs and supplementary frames serve to increase the stiffness of the primary frame, reducing axial and torsional deflections thereof upon striking a ball by the stringing across the open region of the head. The multi-frame further includes supplementary bracing interconnecting portions of the supplementary frames alone or with the primary frame in the region of the throat thereof.

摘要： A fixture for inserting and removing locking tubes into and from locking positions in a top nozzle includes a lower traveling plate and an upper traveling plate disposed above the lower plate. The lower plate has hollow flexure tubes attached to and projecting downwardly therefrom. Each flexure tube has an axially segmented sleeve portion which terminates in a lower segmented rim, with the rim being expandable to a first outside diameter greater than an inside diameter of the locking tube and collapsible to a second outside diameter less than the inside diameter of the locking tube. The upper plate has actuating rods attached to and projecting downwardly therefrom through the flexure tubes. Each actuating rod has a shaft portion which terminates in a lower enlarged nose disposed below the segmented rim of one flexure tube such that movement of the plates away from one another forcibly inserts each enlarged nose into one segmented rim sufficiently to expand the same to its first outside diameter size wherein the segmented rim will engage the lower end of each locking tube, whereas movement of the plates toward one another withdraws each enlarged nose from each segmented rim sufficiently to allow contraction of the same to its second outside diameter size wherein the segmented rim will fit through the locking tube.

摘要： A tool for removing a locking tube from a locking position in the upper end portion of a guide thimble inserted within a passageway in a removable top nozzle of a reconstitutable fuel assembly includes an inner tubular member attached at its upper end to a bail assembly and at its lower end to a tubular extension having an expandable and collapsable lower end. Also, an actuatable shaft assembly of the tool is mounted for axial movement within the inner tubular member and lower tubular extension and has a conical nose disposed on its lower end which extends beyond a rim formed on the lower end of the tubular extension and an actuating knob coupled to its upper end. Rotation of the knob in one direction causes insertion of the conical nose into the lower end of the tubular extension and thereby increase in the circumference of the rim such that it will engage a lower edge of the locking tube when the tool is forced in an upward direction. An outer tubular member of the tool is disposed about the inner member and mounted for slidable movement therealong. The outer tubular member is manually moved in a reciprocating manner to deliver a series of forceful impacts to the bail assembly of the tool which impacts are, in turn, transmitted via the inner member to the lower end of the tubular extension. When the latter is expanded into engagement with the lower edge of the locking tube, the force of each impact will displace the locking tube in an upward axial direction to remove the tube from its locking position.

摘要： A method of reconstituting a nuclear reactor fuel assembly having a top nozzle subassembly attached to the upper end of its control rod guide thimble wherein the subassembly includes an upper hold-down plate, a lower adapter plate, and a coils spring interposed between the two plates. A force is applied on the hold-down plate to compress the coil spring and transform the subassembly from its operation mode to a reconstitution mode. The wall of the thimble is severed just below a first attaching retainer mounted on the end of the thimble which defines the upward limit movement of the hold-down plate during the operation mode. Containing fingers are placed on the subassembly for removing it as a contained unit. The top nozzle subassembly or a new replacement subassembly is then replaced on the severed thimble in its reconstitution mode and a second attaching retainer is mounted on the upper end portion of the severed thimble in redefining the upward limit movement of the hold-down plate. The force is then released from the hold-down plate whereupon the top nozzle subassembly is transformed from its reconstitution mode to its operation mode.

摘要： A modular in-core flow filter for capturing potentially harmful debris during cold hydrostatic and hot functional testing of a nuclear reactor. Since testing is carried out before fuel assemblies are placed in the reactor, multiple filters, each being of the same size and configuration, are temporarily installed on the reactor lower core plate. They fill the space which later is occupied by fuel assemblies when the assemblies are installed in an operating position. Each filter includes a square metal base having a single axial opening which desirably covers four holes in the core plate. Fine mesh and coarse mesh screens are secured in the axial opening and the unit is removably attached to the core plate by brackets which extend through the metal base and engage the underside of the core plate but are actuated into position from the upper side of the core plate. When functional flow testing of the primary coolant system has been completed, the filters are removed for subsequent use in other reactors. Any debris caught by the screens and in the bottom of the presssure vessel is removed and the fuel assemblies are then loaded into the reactor.
