A spliced conveyer belt assembly having a belt which includes: first and second belt ends; a load carrying ply which is coextensive with the full length of the belt; first and second reinforcing plies spaced from the load carrying ply, the first and second reinforcing plies being disposed adjacent to the first and second belt ends, respectively; and a hinged joint having a plurality of first belt end fasteners and second belt end fasteners, each belt end fastener including first and second apertured plates disposed respectively adjacent to the respective sides of the belt at the respective first and second belt ends, and a bight capable of connecting the first apertured plate to second apertured plate; at least one securing device which is capable of extending through the apertures in the first and second apertured plates and through the belt; and a hinge pin extending through the bights of the first and second belt end fasteners.

Spliced conveyer belt assembly

A gate valve apparatus which includes a housing having a passageway defined therein for a fluent material, a generally planar gate, and apparatus for supporting the gate within the housing. The apparatus for supporting allows movement of the gate in opposed first and second directions that are generally parallel to the generally planar gate. The apparatus also includes an annular seal carried on the housing around the perimeter of the passageway and apparatus for moving the gate in a direction substantially perpendicular to the generally planar gate. The apparatus for moving includes a first and second shafts, the shafts have a first and second axial portions that is disposed in eccentric relationship to other axial portions of the shaft, a roller is carried on each of these eccentric portions. A roller including a bearing allowing free rotational movement is carried on each of these eccentric axial portions. The apparatus may include structure for rotating the first and second shafts to urge the rollers against the gate and move the gate to compress the seal. This apparatus may include at least a first pneumatic cylinder and a mechanical over-center linkage coupling the first pneumatic cylinder and the first and second shafts. The linkage may have a locking position which the linkage will maintain after once been attained followed by a failure of the pneumatic supply to the first pneumatic cylinder. The linkage may include an S-shaped arm fixed to the first shaft and a second arm fixed to the second shaft. Each of the various embodiments of the invention may use bearings that are needle bearings.

Gate valve for fluidized particular material

A remote control apparatus for removing from one of a number of filter pits, and loading for protective storage in a disposal drum, radioactive filters used in nuclear power generating stations, and for replacing spent filters. The apparatus includes a transportable base adapted to be placed adjacent the respective filter pit and a hoist mechanism mounted on the base. The hoist mechanism includes a vertical tower or mast mounted on the base, a generally horizontal boom mounted on and extending outwardly from the top of the mast, a grab mechanism for engaging various specially adapted articles, including spent filters to be removed and new filters for replacement, means for operating the grab mechanism from a remote location, a lift mechanism for supporting the grab mechanism from the outer end of the boom and for raising and lowering it in a vertical path, and means for operating the lift mechanism from the remote location. A drum turret is mounted on the base for rotary movement about a vertical axis spaced from the vertical path, to and from a filter receiving position wherein a storage drum carried thereby is placed in the aforesaid vertical path to receive a removed filter to be lowered therein by the lift mechanism. The drum turret is adapted to be operated from a remote location. A second turret is mounted on the mast intermediate the base and the boom for rotary movement about the aforesaid vertical axis and has preferably two radially extending platforms adapted to be positioned selectively in alignment with the vertical path of travel to receive from or locate for the grab means a spent or new filter or other article to be supported by the second turret. The second turret is also adapted to be operated from a remote shielded location.
